Got a G.M. owned 2018 ZR2 diesel that was from the Las Vegas Auto show with 98 miles on it. Driven for a little over a year with 13,000 miles on it, haven't had a problem. In fact this diesel is a little jewel, it's very fuel efficient and is unbelievably smooth. I would recommend the 2.8 engine choice to anyone interested in a diesel.

Hey Bob, neighbor here... got my 2017 Z71with the 2.8 diesel from same dealership had just under 18k miles on it.. so far so good, the truck is great! i though i had a DEF issue in that the indicator reads "OK" level but the sliding gauge just to the right stays at the bottom end..but I seen others with the same indications.

"Don't delete your pickup" AGGRESSIVELY NODS lol, love it. Great videos.

Ok man your almost correct! I’m a cummins engine tech, though I’ve worked for ford, gm and cat. All of them except cat (cat has only the cgi / EGR system, diesel exhaust fuel injection, doc and dpf) use the following aftertreatment system. Components vary in size and manufacturer, but they all go in a specific order. Sensors can be mounted either in the component or in the exhaust pipe as well. Here’s the order: engine control module, oem ecm connector, EGR exhaust temp, EGR exhaust pressure, turbo vgt, diesel fuel inj, exhaust gas temp, inlet NOX, doc intake temp, inlet dpf temp, inlet dpf pressure, dpf differential pressure, outlet dpf pressure, dpf particulate matter, dpf outlet temp, def controller, def temp, def pressure, def quality, def heater, def filter, def doser valve / inj, scr catalyst inlet temp, scr catalyst outlet temp and outlet NOX. The following is the order of the exhaust components: exhaust manifold, Exhaust gas recirculation cooler, EGR valve, turbo, diesel oxidation catalyst, diesel particulate filter, diesel exhaust fluid decomposition tube (def comp tube may be integral to the exhaust pipe), supplemental catalyst reduction canister (scr cat), muffler / resonator and tailpipe. These sensors and components are in a specific order and only function in that fashion. They are divided into 6 systems: exhaust gas recirculation, aftertreatment system controls, diesel exhaust fuel injection, diesel oxidation & particulate filtration, urrea / def injection, supplemental catalyst reduction. These aftertreatment systems are controlled by the engine control unit via the oem body controller and wiring harness. Simply put they’re supposed to make your engine more fuel efficient for more efficient power and less ozone polluting. That the theory, but it doesn’t mean that’s the way it actually is. More money for more crap that will eventually be replaced by god only knows what in the distant future.

While compact truck shopping in 2018 I narrowed my choices down to a Tacoma TRD Pro and the Colorado ZR2. I went with a 2018 ZR2 diesel and the truck has been problem free. Great explanation of the sensors and such on the exhaust system.

When you see brand new semi trucks broken down on the side of the highway its probably a emissions issue. Major problem in big trucks.

TFlorida1 ....all the information I have is from actually haven driven after treatment equipped Freightliners, Volvos and Internationals since DEF became federally mandated. My personal experience is that emissions related shutdowns have been quite frustrating. I’ve had multiple breakdowns related to after treatment systems. The only other breakdown I’ve encountered, over the last several years, was a broken clamp on the charged line from an intercooler. I’ve had multiple failures to regenerate, low DEF dosing, clogged DPF filters, and coolant leaking from the DEF tank heater into the DEF itself. In fact, thanks to a problematic DEF system, I spent a Christmas at an International dealership instead of with my family.

Nice video! I appreciate your showing all the sensors and fuel injector. Your video ended an argument, as there are a lot of people who do not believe me when I tell them the 2.8 has a 5th "indirect injector". You saved me a trip onto my dirty cold garage floor to photo it. Sending a virtual beer your way sir. The actual injector is the same part as the big Duramaxes by the way. From what I have seen, the Diesel particulate filter sensor is the most common issue, followed by the DEF injector. My Canyon has 38K miles on it, no problems to date knock on wood. It has a GDE emissions system intact tune, which limits speed to 124 MPH in the event of a DEF code - LOL. The final version of that emissions system intact tune (before the EPA storm troopers moved in) reactivated DEF injection, which I prefer as it seems likely the injector is less likely to crystallize into a non functioning lump if it is being used and not dormant. That and running the DEF system negates having to drain stale DEF out of the tank - one could still get a bad DEF message even with the tune. All versions of the intact tune turn off EGR, which is a great thing as the 2.8 runs a lot of EGR. I recommend everybody install a catch can. I have a Provent 200, it catches probably 8 oz of oil between changes. Taking the oil mist out just leaves dry EGR soot for stock engines. Mist plus soot = intake clogging goo... Of course, no dry soot and no PCV oil in the intake is best, that is what the combo of catch can and tuning gives you. Averaging 27.5 MPG lifetime over 28K miles with the tune (stock was 25.1, and it has stock sized but knobbier Cooper AT3s on it since tuning, which reduce mileage), breaking 34 MPG cruising on the highway at 70 MPH is not uncommon. The truck is a 4x4 long box. The tuned 2.8 hardly ever has to rev past 2,000 RPM. Stock it had good low end, tuned it has, so much low end torque it is kinda ridiculous. Also have the GDE transmission tune, it shifts a lot earlier and firmer to take advantage of the torque. They are gonna have to pry this particular Canyon from my clutching fingers :)

Great video. As a GM dealership mechanic who works on these systems. I cant stand the DEF system. Thanks for showing some of the sensors and explaining what they are. Most customers dont believe anything we say when trying to tell them what is wrong when they are upset. Hopefully they watch videos like this to get a little more informed.

Its the nature of Urea to form crystals, ever hear of gout.?

Thanks for info. Well explained reality on DEF systems.

I had a similar issue w/ my new 2019 ZR2. It took 2 different Chevrolet dealerships to find/fix the DEF problem. It was NOT related to an obstruction in the fluid system, but simply a wiring harness coming loose and burning the insulation on the exhaust pipe causing a "short" in the harness-to-computer circuit. Since correction, I have had excellent performance and am very happy with it.

Your mention of DEF crystallizing is kind of what I suspected happened when DEF sits for extended periods of time. Sounds like that is exactly what caused the DEF injector to plug up. The fact that I don't drive my 2009 Duramax much is why I haven't traded it towards a newer truck. Sounds like leaving a DEF equipped truck sit around for months on end is a bad thing for the DEF system. I've had my 2009 since August of 2009 and it just hit 56,000 miles last week. Nope, I don't drive it much. I'm starting to research a Colorado Duramax as a daily driver, which is how I found your channel. I binged watched a bunch of it today.

Thanks for showing all the part in the exaust system. I'm about to change the DEF hose because the DEF fluid FROZED or something. Temporary repair.......

I had similar issues with my ZR2 too. Had to go to the shop three times. First time was for the DEF injectors being clogged. Second time was for a NO2 sensor and the third time was for a DEF module or something related to the DEF system ECU. I still enjoy the truck and hopefully these issues have been resolved but you're right about most of the issues we're seeing being DEF related. The powertrain I know is solid.

I was thinking of getting a Diesel for my next truck but after doing the calculation I changed my mind. I found that Diesel cost more plus the cost of repairs and then the def fluid. I just didn't feel comfortable at the point so I went with a 5.7 V8 gas engine. Thank you so much for explaining this so clearly.

The only plus side to a diesel you may not have factored in is the resale value. Typically diesels have higher resale. Usually enough to cover the cost of the diesel option.

Had my def pump replaced at 15k miles. Sold the pos 2.8l Colorado at 38k miles with other engine/transmission problems

Had this problem multiple times, .have replaced injector . Used only GM Def still get this code. Usually goes away on its own. Love this truck but am glad still have a 2011 ram cummins to drive when this one is in the shop.

I had the problem as well , 12000 miles, the warning was general engine light , pur DEF in the tank but was still full , the dealership took care of the problem in 2 hours sweet , My highest mileage is 26 average 22 around town !!

Good video man. Higher RPM's and engine loads are the only way to avoid (but on a majority) of the exhaust issues. Tier 4 final equipment has similar exhaust, but has far less issues because the exhaust runs so much hotter. DEF when left to sit gets pretty nasty, so the faster it flows through the better the components survive.

If I ever have any problems related to the exhaust system, it's getting deleted.

Thats a complex exhaust system, I just don’t know how all of those components will hold up long term, especially if you off road. I’ll stick with gas for now.

Had the same message, “Bad DEF” on a long trip. Luckily I got to a small town and a service station had some DEF. Put a new gallon in and the message finally went away after 15 miles of driving. The truck had just been serviced by a dealer and the only DEF put in it was from GMC. Have had a couple other issues....On last regeneration I was driving on a freeway for 45 miles and the light wouldn’t go off....Drove it to the dealership and was told that my “average speed” while driving was too low and this was causing issues...I drive it like I do any other vehicle and couldn’t find anything in the manual about operating speeds. Love the truck, but not sure I’d buy it again.

If you're ever back at the same dealer I'd love to know what their specification for average speed needs to be. Like you said the owner's manual lists nothing. That answer from the dealer is BS. How can a diesel UPS or FedEx truck stop and start all day long? I'd buy DEF from a truck stop. It's usually about $2.79 a gallon near me. Nobody goes to the dealer to buy DEF and chances are it's been sitting around a while. Sounds like they are selling you old DEF and blaming your driving habits. As long as the truck can get to full operating temperature speed shouldn't matter.

Thank you for sharing your personal owner's experience ! Looking forward to more videos on living with it. I want a Diesel powered vehicle, I really do . . . BUT . . . all this Bull Crap with the EPA and their unrealistic emissions level standards and stupid high MSRP does not help. At the end of the day the owner is left to deal with all the aftertreatment system's WOES and nightmares. It even makes me think there's an "invisible force" behind the EPA doing everything in it's power to not let light duty diesel vehicles gain a stronghold in the USDM and discourage would be owners from even considering the VERY FEW available today. And I, just like you, do not judge and criticize anyone who deletes their vehicle . . . well, OK, sometimes I do . . . but only the Assholes in their Brodozers rolling coal giving a bad rap to Diesel. Those people don't see they are digging their own "graves", singling themselves out for all the wrong reasons and getting all kinds of unwanted attention from Big Brother. 👎😔💩

They definitely don't want people to own a economical diesel engine they can't abuse with diesel prices as they do with gas prices

I've dealt with a similar problem with a Ford system. Assuming they operate under similar principles, the def system does not stay primed between injection cycles. It is purged and remains dry from the pump to the injector when not in use. Given that info, I could imagine that residue or pooling anywhere in the system could generate crystalization that would get picked up and pushed forward to the injector. This is speculation but could provide a possible cause in your situation. If this becomes a reoccurring issue I would assume an engineering flaw in the system. If it does not then it could have been environmental and a one off situation. Good luck and I hope the problem is sorted for the Long haul.

Just 1 issue? You are lucky my friend. My 2018 has had many issues since i purchased it new including a new rear end at 800 miles. I wont be keeping at past the warranty.

I have a 2017 GMC Canyon and I find it interesting that yours used only 1 1/2 gallon to fill. Mine, when it says low uses nearly 5 gallons. So I think you are spot on with the DEF having crysalized in the tank.

It wasn't showing low. I topped off the DEF in case the DEF quality in the tank was actually bad to try and delute it. The tanks are about 5.5 gallons.

I had the Z71 DuraMax. Just Loved it. I never had an issue with the Engine... I turned the Truck in before the Lease was up for another issue. The Truck would eat up every Radio the Truck had. It was frustrating that GM refused to troubleshoot the problem and fix the Short it had in the dash. Instead they would switch out the Radio after each one died on me.

I got a 2019 ZR2 extended cab long bed and it's already got 20k on it. I run 51 psi in the tires, use Mobile 1 5w-30 Dexos2 oil changed every 6,500 miles, always carry around 850 pounds of cargo in the bed for my work and set the cruise control to 55 mph on highways doing 75/25% hwy/city driving most of the time. Since I live in southern CA I spend a lot of evenings in traffic on my 1.5-2 hour commute home. I haven't reset the trip #1 odometer since I got the truck and over the 20k span the average mpg is 27.9. The best mileage I have ever got using the trip #2 odometer was 31.5 mpg over a 610 mile trip before refueling. It was mostly 55 mph highway driving with little traffic. I have been extremely pleased with the truck especially the interior comfort, electronics and noise isolation. The only thing that bugs me which I have not addressed is that sometimes when I turn the blower fan on the a/c kicks on even though the a/c switch is off. My dad has a 2012 Mercedes E320 Bluetec diesel with 75k miles on it which is a fun car to drive but he had the heating element in the def tank go bad twice. The first time at 35k the dealer replaced it for free. The second time at 60k the stealer wanted a whopping $3k for the repair. He declined the repair and now drives it with the check engine light on. Luckily the computer didn't derate the engine into limp-home mode or anything but you're absolutely right in that these complicated exhaust systems are the death of modern diesels and will be the first thing to break down. BTW, i also have a 1987 Mercedes 300TDT station wagon with hydraulic self-leveling suspension, a 3 liter inline 6-cylinder diesel that gives 29 mpg average overall with conservative driving even with 431k on the odometer! I've owned the vehicle since it had 120k on it . .Only had the head gasket replaced once, head fully reconditioned, replaced injectors, a/c compressor, alternator brushes, glow plugs several times and nitrogen spheres for the rear suspension. Also suspension and brake components that wore out. I do all the work myself on that engine as it is very archaic and lacks computer control.

The newer system with the exhaust fluid is way more sensitive to fluid/fuel quality issues. Buying DEF from truck stops I make it a habit of dumping the nossle downward before bring it to the fill in the truck. Seem the nossle aways has fluid in it being stored upward. I have even run into issues with fuel in far Western States being that it is some sort of alternative bio fuel.

It's an ok engine and I have 154k on it but it has no after treatment system. I'm eventually going to replace it but not with another diesel. I'm going to go with the Tacoma too.

Thanks for the transparency. I was hellbent on getting a colorado diesel but the scr scared me away. We use way too much salt up here. Ended up with a full size gas truck. The diesel would fair better in Texas or California.

@@RepairGeek yeah but spraying FF on all those sensors isnt going to make much of a difference because they're all attached to the hot exhaust system. I can imagine the bolts holding them on will rust and seize and likely have to get cut off. Seems like too many possible points of failure.

Those bottles with the built in accordion type funnels cause issues. Residue lays in the crevices. Use your own funnel and clean it afterwards.

The price we pay for cleaner air. But agree absolutely to the frustration.

Don’t have to worry about DEF in Australia, or the EPA, thankfully . 14000km so far its been good. Did a 6000km pulling a camper trailer trip to Queensland last year and the only problem was hitting a kangaroo on the return trip. We have the SUV version called a Holden trailblazer, and it’s been awesome. I think the EPA has broken your diesels, sad, that’s so sad.

Hey so I'm pretty new to the diesel world, deleting is getting rid of all the epa exhaust crap including the def stuff? Aside from ease of use does this give performance gain too? And since those sensors are gone does it take away that epa required 65mph down to 5mph when there is an issue?

just a thought, your just getting into cold weather, could that have something to do with your problem ?

Yep the crystals dissolve in water. I work on Cummins and soap and water is an authorized way to clean the injector.

I have the same problems, many times 1st day of vacation, replaced cpu, reset itself 5 or 6 times even after it started limiting the speed. always seems to start when it gets about a gallon to gallon and a half low on def. all they seem to do is reset the error. getting ready for a change. My jeep grand cherokee 3.0 never had any problems.

I had the same issue, z71 2.8. I live in a cold state, the diesel heater went bad and the DEF crystallized because it wasn’t heated properly. It was under warranty and GM fixed it for free. I don’t have anymore issues now.

As a former service advisor, getting the wrong part is a generic excuse for the repair taking long and is almost never true. It’s just to buy time, provide the customer an update and shift blame.

Def fluid caution make sure what your putting in Def tank is not expired read up on how to Decipher Expiration codes . When gen starts keep driving till it regenerate is complete . Wipe def nozzle before pouring in to prevent crystals from dropping nozzle . In others wards be neat .

DEF and DPF systems are the Achilles Heal of all modern diesels. I’ve driven commercial trucks with over 2 million miles on the OD without incident. Since I’ve been driving newer tractors, all I’ve come across is problems. The DPF system tends to not regenerate properly, causing the DPF to become clogged and requiring replacement, The DEF system tends to be finicky and the Urea tank isn’t designed to resist freeze up in extremely cold weather. It isn’t manufacturer specific, as I’ve seen it happen in Mack’s, Freight liners, Kenworth’s and Internationals, running Cummins, Detroit’s and Paccar’s drive train. My personal opinion is that DEF/DPF systems are an after though. That is why Glider Kits have become so popular, why company’s tend to keep older tractors for longer and why you see so many newer trucks on the side of the road with their hoods up.

I’ve got over 23,000 on my 2017 Chevy Colorado with the 2.8L Diesel engine. Mix of highway and city driving and the truck runs great. No problems at all.

Love my Duramax 2.8 starts and drives even at -20 outside temp then it warmed up to +19 thats when i had an issue def pressure regulator went out 13,000 miles on my truck so local dealer fixed it under warrenty. Just passing it along.

The way it does that is the injector dribbles a little and it crystallizes. Over time it builds up and clogs the tip of the injector. This is a very common failure on def equipped trucks.

My work van is a MB Sprinter...to open the DEF cap i need slip joint pliers...the crystals seize the cap on. Diesels are nothing but trouble...hard to start in the cold and the cost of the engine makes it cheaper to burn gas.

I think the diesel adds a lot of character to the truck. I've never driven a gas Colorado. I just wanted a diesel small truck. The diesel feels slow when you're going highway speed and floor it but, quick acceleration from a stop or slow roll feels much quicker. Plenty of people have had zero issues at all with the diesel engine and hopefully this is my last issue but, either way I'll document it.

@@RepairGeek if you want better throttle response, then check out the Pedal Commander which is a plug & play unit that does not make any changes to the truck's computers so it does not risk voiding the warranty. There are plenty of videos on KZread showing them on a bunch of different vehicles - once you have it you will never want to drive without one installed.

The 8L45s in the gas Colorados have issues. I wouldn't be surprised if it's found to be "adaptive learning" code related and an indirect result of EPA fuel economy regs.

I cannot fathom that truck exhaust system in a New England ( NaCL) winter! OMG

@@arnehurnik def is for NOx and has nothing to do with soot... Its active sabotage for resale and overall efficiency.

Welcome to the world of every semi truck driver. I am an owner operator. I own a 2012 Volvo 780. The aftertreafment systems are all junk. I've spent over $15k on my truck in the past year. Currently my check engine light is on. It's a great truck. Great engine. After treatment system is another story.

I have a 2016 Z71 diesel with a bit over 168,000 miles on it. The only real problem I have had are with the NOx sensors. Having worked with industrial NOx control systems I can tell you that this technology is the same as used on power plants for their NOx emissions and is well proven. Instead of urea (DEF) solution they use straight ammonia, but this is needed to work with the catalyst to reduce the NOx to N2, which of course makes up 79% of our air. The problem with DEF is that the urea is not super stable and over time will oxidize, which is what the initial code is setup for. I never let my truck sit idle for more than a day or so, which eliminates that as a possible issue for me. I agree with you and everyone else that the "step-down" program the motor is programmed with is a safety issue. Last year I drove from Atlanta to Cincinnati and 60 miles before I got there that same fault message came up on my display. I ended up spending the entire weekend at a local dealer getting this resolved and never did attend the trade show I went there for in the first place. What is worse however, is if you are in a remote area like the Grand Canyon, or out in the desert somewhere with no cell service, there is a real reasonable probability that you could be stranded in a place where your safety is compromised. My opinion is that the program needs to allow you one day's worth of driving before shutting down so you can get home. For me a total of 700 to 750 miles would do it. All I know is I was over 400 miles from home when my NOx sensors last failed, and that is not right. I otherwise love the truck.

All thanks to the EPA.

Just remember what Pittsburgh looked like in the 1930s - 1940s; "the Smoky City." Also look up what Los Angeles still looked like in the 50s - 60s; Smog haven. Not commenting on the reliability or lack thereof for strict emission controls, just saying remember the air hell that's being avoided.

i had the exact same problem with my colorado too.

Temperature will cause it to plug! I run several Peterbuilts that did that! Change DEF filter ever fall when temp drops below 32!

So is the diesel worth it with all those additional failure points? Have a 2500 Ram 6.7 with a bad Cat system. Its about 5' long and $8000. Luckily it was replaced under warranty.

Seafoam or fuel additives is a must to protect those sensors and prevent dpf complications later on!!

These problems usually occur from idling around all the time, very simple

i have always loved diesels but never owned one, just drove them in work trucks. but thats the same mpg as my 4 cylinder Tacoma hauling my tools around town...i really dont even want that much torque and horsepower...id gladly have no turbo if it meant no need for DEF. in fact an 8 speed manual with a gutless engine would be fun to drive, you plan for the hills and keep your rpms up...just like the old trucks but with better transmissions

So overall, how satisfied are you with the ZR2. I've been looking at the Orange Crush ones and would have to get the longer bed but unsure if it will hold all I need. I have a GMC Sierra now but would love to have an orange Chevy. Go Browns!

I really like the truck like I said in the video I can get 30mpg if I turn the AC off and drive conservatively. It's easy to park, comfortable, rides well, this truck is a much more useable size for my needs. I had an 2010 F150 before this and unless I was hauling building materials the size just felt unnecessary. At that time, a ranger was the same price as an F150, and got worse mileage, no backseat, and 100 less HP. I've had this truck loaded with firewood halfway up the back window and I barely noticed it was there. I've towed my snowmobile on a utility trailer and it was the same way. I didn't notice. I don't really have a use for a truck that tows 12,000 lbs. My dad has a Z71 Colorado duramax and the ZR2 has probably a 1 or 2mpg mileage penalty compared to a standard truck. The leather seats in the ZR2 have more cushioning than the cloth in the Z71. Leather is optional in the Z71 I believe. If you need bed space you may want to look at a Z71 crew cab long box truck. The ZR2 is only available with an extended cab and a long box. The back seat in the extended cab is tiny. My only complaint is the truck is slow at high RPM. Merging onto a highway in heavy traffic usually requires wide open throttle and a prayer. Around town and normal driving it's fine. The engine makes enough torque down low that it feels faster than what it is in normal driving. I'm from Akron so yes, GO BROWNS.

My mileage warning would drop dramatically over a few days. 900 then 3 days and 120 miles later, drop to 200 miles, then 25 miles later drop to 60 miles. My 2015 GMC 3500 had 149,xxx when I bought it in January 2018. These problems came up in my first 7000 miles. It would just eat through def fuild! I switched to GM DEF and within 1000 miles it started running better. I now have accurate warning messages and reduced fuild consumption. 15,000 miles later and no issues.

I depend on my vehicle so much. The fuel economy would be nice but one screw out like that would pay for a lot of gas.

Engine Regeneration? It knows where it stands. Did you Fac w the intake?
