Coolant bypass valve

- Sacramento, CA, USA

My engine maintenance light will not shut off due to a engine coolant bypass valve circuit short to battery. I also have warm fluid dripping on my feet when ac is on. The dealer says water under the dash is from from recalled roof rails. There has been a recall for code that pops up on my mechanic Toyota number20TA04. Dealer says he does haven't code so toyota hasnt issued any issues or re all for engine bypass valve. Toyota now has a class action law suit for this part. I can't afford $700 repair, can't see the messages or my speed due to the engine maintenance required on my screen which can't be reset. This is dangerous and can cause the need to have engine replaced, start engine fires. Toyota has known this issue for 5 yrs and needs to be held accountable.

A message popped up on my dash "Engine Maintenance Required - See Dealer". After further research this is a known issue with the Toyota Rav4s. The coolant bypass valve gets stuck open/closed. I took it into Toyota and before they even looked under my hood, he read the message on the dash and said "I know what it is". After paying $742.16, it was fixed. My local mechanic was not aware of this issue, so I had to go through Toyota directly. If someone cannot afford $700-$1,000 repair, they risk their engine overheating. Toyota is aware of this issue and they have not recalled this part in their vehicles that is consistently failing.

Toyota RAV4 2019, Coolant Bypass Valve issue. The car began displaying the message -??engine maintained required visit dealer-??

- Murfreesboro, TN, USA

my Toyota RAV4 2019, At around 44500 miles a messaged started to showing up, message was "Engine Maintenance Required" "Visit your Dealer", the message cannot be disregarded, it blocked important part of the dashboard. No other warning light or failure lights were on. Upon taking the vehicle to the Dealer, agent mentioned it could be a non reseted counter for the regular 5000 miles next service reminder, however such maintenance wasn't due, after check by additional person, technician and scan, it turned out to be the bypass valve sticking, code found P268115 and suggested repair for around $900, since vehicle is no longer under the limited warranty cost would have to be covered by the client. Agent told has to be done other wise cooling system for the engine could be at fault causing overheating, and ended up on a mayor engine failure by overheating. It doesn't seem to be a normal failure found on the users manual, hence could be a possible manufacturing fault which Toyota is not covering.

"Engine maintenance required" warning light came on and unable to bypass at all, leaving driver unable to read odometer or speedometer while driving. Had to go to the dealership 2 days in a row before they finally addressed the warning. Service staff informed this is indicating the coolant bypass valve is damaged or has failed. Also informed that this is a very common issue regardless of location, mileage, or usage of vehicle and will happen to all RAV4 owners of certain years eventually. A quick google search will show this is an extremely common issue and a result of using inferior quality parts in manufacturing. Toyota should recall this issue asap and reimburse drivers as many people have had the same problem. Had to pay over $600 at dealership to address issue that Toyota's manufacturing caused and to be able to have full usage of vehicle again. This is a dangerous issue if drivers without financial means to address this problem are driving without being able to use their vehicle display tools among other issues regarding the engine.
