I have that exact car... even color. I'm having the exact issues and the dealership can't seem to find the problem after I spent money on a full diagnostic. I went back after I found the code and they replaced the water pump. At nearly $900. A month later, the problem is back. Now you show me this and I'm sure that's the issue. Thank you so much!!!

Brightest smile on you tube. Explains complex mechanical "stuff" very clearly. In a word...Great.

Thanks for taking time out from your "billable hours" to show this problem.

Thank you sooooo much sir. This really really helped explain whats going on woth my 17 prius. I have 250k on it and its always ran perfect...but now, it all of a sudden needs work. I love this car so much, its been so good to me. Now its time to give back and tune her up like new. Going to bypass my heat exchanger for now....but eventually replace that part. Cheers buddy

HI!Great video and details what is going on, when you mysteriously loosing coolant, that is not leaking or not going into the engine. Just dropped off my 2018 Prius Prime at the dealer with exactly the same problem. The person accepted the car at the register said is "a known issue" for these cars and yet I didn't find almost anything online until I got across this video. I got this car as a Toyota Certified Vehicle and I am just hoping that this is covered by that or there is a recall on it. Thank you for the great video.

Thank you Peter

good to know. muchas gracias

Yes, I had this problem on Prius v 2012. I notice when it dam on rainy or snow day engine went into shaking mode. So what I did was to losing the coolant engine reservoir cap. It help stopping engine shaking but I will have to refill engine coolant.

Thank you so much for your video…I would love to see a video showing the hoses bypass of the heat exchanger

How is it going?

Can this happen to the Prime version? I’m assuming both version has the same set up except for the larger battery.

So why did they have three hours of diagnostics when they could have added UV dye and sent him away and checked it a few days later?

I had this happen 6 months after buying new…apparently coolant is routed to cat converter for quick engine warmup…it was covered under warranty…but that was a $9k warranty claim😮

Petr, Is this 2017 no longer under warranty?

It should be noted that the gasoline engines for the hybrid vehicles that Toyota produces go through an exponentially higher number of hot and cold cycles compared to a full, 100% gas drive engine. So, you will see a Prius engine, mainly from 2009 to 2014, have a head gasket failure between 120,000 and 150,000 miles. So, the newer ones are better engineered and, while this particular car was obviously used for some sort of delivery or taxi type service, we don't expect to see head gaskets failing at the rates that the previous generation suffered from. The heat exchanger is a unique element to the gas hybrid vehicle. It is an efficient use of heat and is wonderful engineering. Considering how easy it is to total a Prius, or any hybrid or vehicle with radar sensors in the front and back by any manufacturer, after an accident, those heat exchange systems should be readily available at junk yards at an extremely good deal. It's the catalytic converters that they demand all the money for.

Hi Where is your garage located?

Please advise. 2014 Prius losing coolant, easy fix, bypass heater exchange in catalytic converter?

Hi, is it save to bypass the pipes?

You should show changing a Toyota wheel bearing. How you deal with the circlip?

Thanks 🙏

THANK YOU. Totally correct! Same for my 2017 Toyota Prius (Canada)...the part is not available here but should be a recall and warranty. Hope to find out what happened after you made this video. Driving without heat and either replacing coolant (without a bypass) or burning gas. This is known issue by Toyota...how to get the part (1,700 in Canada AND some compensation?...help!) Have a great independent brilliant mechanic who figured this out after a lot of guesswork you know where.

Hello, I have a 2017 Prius with 120k miles and suddenly I see that the engine coolant reservoir is empty while the inverter coolant is full. I didn’t find any driving underneath and the engine doesn’t overheat. Why is it happening and what should I do? Thank you!

My 2016 Toyota Prius has a refrigerant leak. I fill it up every day and it runs empty a few hours later. I don't see any signs of leaks on the chassis. I've driven it for about 270,000 miles. Toyota Longo 4s said it would cost $4,800 to repair it because they found water in the engine with a probe. Is this crazy? Such an expensive repair bill!

Being ICE doesn't run alot, coolant is piped thru heat exchanger so the interior of car heats quickly in sub degree weather.

I have a 2015 with coolant leak from bad heat exchanger. you mention that there is a 2013 Toyota TSB which says the coolant heater can be bypassed. Any idea why my dealer is unaware of this? When you say bypassed, do you mean I can connect the hoses together, or simply block them off. I assume you mean connect together, this is a $2700 back ordered part. Thanks!

So I had this problem & did the bypass- it worked for about -6 months or so - I drive about 800-miles per wk Later I found out that my overflow coolant was leaking into my engine & of course blew the engine- ques - how long so we do the bypass for like only -a wk or 2 ? I’m told I still need to fix the heat exchanger - I did replace the engine?? Thanks from CT

I'm hoping to rule this problem out, but I can't tell where the leak's coming from yet. We had about 2 tablespoons of coolant that dripped down from the front passenger wheel-well onto the garage floor. The engine reservoir only needed a splash to bring it up to the FULL line. Inverter is full. Don't see signs of any leak poking around the top of the engine, trying to look around the sides, and under the car the best I could without raising it. No coolant signs around the tailpipe. Needs an oil change this weekend, so we'll be lifting it, and looking further.

Because it's mostly new kids just out of tech and they have little experience and some are ashamed to ask for guidance.

I noticed in the last video the new highway 101 sign. I wonder if that is a hint for us for something or perhaps a gift from a fan.. Anyway Pete, this Japan built Prius is one owner at 104 thousand miles. About 21k/year.. makes me wonder if he is an ubershare worker. Anyway. You asked me about recalls. This unit has possible faulty locking parking brake, hybrid PCU connection could short out to the box, and also if purchased from Gulf States dealers the spare was not set properly at PDI. That's all I see for recalls. Toyo unfortunately does few recalls and only if absolutely necessary as you maybe know from the service writers. Some people were denied oil ring repair if it did not drink over a quart of oil for the 2.4l-4 bangers of ten years ago.. maybe it was a TSB but I didn't care to look through them this morning. Peace to you crocodile.
