I owned 2017 Sierra 1500 with the 5.3 liter engine and 8 speed transmission. I traded it in at 55000 miles for a RAM 5.7 liter Hemi. The a/c condenser went out at 20000 miles would have cost 3000.00 to fix. (Still under warrantee) The concern I had was the 8 speed transmission. It shifted really hard in 1 to 3 gear. There was an audible clunk and shudder. GM continually denied they have a problem with that transmission, although it is no longer available and if you go internet surfing you will see lots of sites complaining about the same issues I noted above. I will never buy another GM product.

Thank you!!!!! I was really looking into buying a 2018 GMC 1500 Denali. This totally changed my mind.

I'm glad I saw this. I was looking at a white 2018 GMC Denali with 80k miles. It's a shame. These are great looking trucks.

Wow recently became my dream truck totally ruined after this video …

I just replaced my transmission on my 2015 GMC Sierra Z71 4x4. Replaced all 4 shocks as well. Now it drives super. Damn smooth. Like it’s brand new. Shifts are smooth as butter 🧈. I had a super duty transmission installed.

Bruh i just picked up a 16 denali sierra praying hoping wishing it lives up to my 99 silverado😂

I have a 2014 GMC sierra v6 and the oil gauge fluctuates even after the truck is warmed up. Dropped below 40 once but mostly it stays at 40 while idling. When driving it goes between 40 and 70. Any help is greatly appreciated. I’ve had the truck for three days and I bought it for $24,000. I think I messed up after reading these comments.

Wow is this ever a good review for once! This guy knows his trucks.

I own a 2014 Sierra and I approve this message, I can’t tell you how many issues I have had since owning this truck, it has really been a nightmare. GMC is trash and I will NEVER buy another vehicle from them again.

$4500 for shocks? 😂😂😂😂

The radio doesn't work anymore shakes at lights ima try to sell it before the engine lights come on good looking truck though but i think ima get a ford

Tran down shifted hard when goes to 1 st gear only when trans gets over a 145 temperature took it to a dealer ship had it reprogrammed and still having the same problem

I have vibration around 70 mph. Hope, nothing else breaks, Lord willing.

I have 2017 gmc sierra i payed 56k when it was brand new to buy it until now i spend over 30k to fix all this problem ac unit , 2 times transmission,injectors, control arms,diferencial.......ext so who ever around me want to buy new truck i m changing their minds to dont buy sierra

I own a 2018 GMC Sierra. Love the look of the truck and the ride is one of the smoothest ever but it has plenty of problems. Radio went out possibly 2400 bucks to fix. Water pump just got replaced at 100,000 which is pretty shity . The AC randomly doesn't work along with my temperature gauge and the cooling fan stays running after you turn off the truck. Not to mention the transmission does seem like it shifts weird. It has the 8-speed automatic. Really love the truck but what a pain in the butt probably won't ever buy another GMC or Chevy again

Thank you for saving me almost bought a 2018 elevation

It's a shame since these are such beautiful trucks, especially the higher trim models, dang!

Intermittent lose of power during slow turns . ( try steering with no power fun ) I’ve had mines loose power at 45 mph and automatically cruise control came on at 55 mph when power restored. Talk about freaked out..2015 V8 4x4 model yes to A/C and condenser going out yes to transmission failure 4K.. lost of braking at slow speeds. but absolutely beautiful truck .. SMH 🥴

Damn I just got a 2018 sierra z71 4x4 😂😂😂😮😮

Currently waiting on the dealer to get back with me on a 2014 with decentmiles. Im starting think the dealer can just keep it. Not a GM dealer either.

Rebuilt transmission at 5k and 4 lifters with a head gasket set for 6k. 20000 miles later need a new engine for 13k. Any buyers? Lol😮

Wow just saw a 2014 for sale ...I guess it will stay on the lot

Don’t do it, I own one, I wish I would’ve never bought it.

Sounds like any other modern vehicle, especially trucks and anything running a V8 motor. The GM AFM system has been a nightmare since it was introduced. If you ever have to do a top end rebuild due to afm lifters or your regular lifters, just do an afm delete and be done with it. The transmissions in these also suck - that’s really the biggest issue I see with these trucks overall because there’s nothing you can about it other than replace it and the torque converter, and pray it holds on long enough.

Please do not purchase GM products right now. I’ve been a fan of GM forever but I purchased a 2019 GMC Sierra Denali 4x4. Had motor blow out 889 miles and all of the rest of the issues that were covered.

Buyer beware and especially gm dealerships for diagnosis they will dodge ( pun ) actual problems as they have been hushed up and repairs can be false. There are aftermarket better north american made parts and youtube videos to help sort out problems - transmission - there is a valve rebuild kit that improves fluid distribution and works great - billet torque converters not gm original , VVT bypasses to run on 8 cylinders only - these things cost $5k to have done - GM class action law suit should be paying for transmission valve changes and torque converter - my engine is 6.2 in 1500 gmc 2017 and runs great ..... now

I own a 2018 gmc sierra ultimate denali and it's a pc of crap. It's a shame that gm isn't even wanting to ignolage that they built a shitty motor and Trans for a while now. If I could get my money back I would in a heart beat. Still have an 03 f150 lariat 4x4 5.0 that shits on these new trucks and it has 260k on it it's just sad because the truck is so nice
