engine maintenance required notification popping up. told i needed to replace engine coolant bypass valve. safety is at risk because the notification blocks my speedometer . dealer has confirmed that the engine bypass valve needs to be replaced and this happens with all toyotas around 40k miles. has been inspected by dealership. notification popped up on my car about two weeks ago.
Coolant Bypass Valve seems to have an issue at 60k miles which seems to happen to many people at mileage even lower than mine sometimes! My dad had this issue on his 2021 Corolla at 50k miles.

"Engine Maintenance Required See Dealer" Message on Dash Display Engine Coolant Bypass Valve I see this incident repeated for the recent Corolla SE and RAV 4 multiple times with no recall/resolution other than Toyota customers should be prepared to spend close to $750 to fix and replace this part that only takes about 20 minutes to be replaced. This is not new to Toyota. This a rip off. A lot money was paid for the car. Went to dealer less than a year ago and purchased a 2020 SE with a $23,323 price tag. Including dealer fees, finance charges and extended warranties the total price comes to $39,000+. I feel cheated as a customer. A practically new car comes with a defective part and it is not covered by warranty?? Come on. I've trusted and recommended Toyota for years. Do you no longer stand by your company name? Need a better resolution. Please.
The engine coolant bypass valve has been confirmed faulty at 47,000 due to failure to actuate. Known issues of engine coolant leaking failure have been reported.
The engine coolant bypass valve is coming up as a code. Around 44k miles. Others have had this problem.
The car is showing an engine maintance required which ended up being a faulty coolant valve
"Engine Maintenance Required" sign came on, I took it to the dealership and was told it was the coolant bypass valve and it would be $800. Upon doing some research is see that this is a very common issue for 2020 Toyota Corollas. My car is still under 60,0000 so I'm surprised I need work this experience done already
coolant bypass valve is malfunctioning in 2020 toyota corolla se. upon research this is a known problem in toyota corollas, camrys, rav 4 and prius, and was recommended to report this as a possible recall. "engine matinence required, visit your dealer" message does not go away. takes 5+ minutes to blow cold air.
The car is at 58,125 miles and I’ve had a “engine maintenance required, please take to dealership” message for the past 3 months which will not go away and is just stuck on my dash. An OB2 port scanner shows nothing wrong, but after a diagnosis at toyota it appears I need a new engine coolant bypass valve. As it turns out, many …

The car is at 58,125 miles and I’ve had a “engine maintenance required, please take to dealership” message for the past 3 months which will not go away and is just stuck on my dash. An OB2 port scanner shows nothing wrong, but after a diagnosis at toyota it appears I need a new engine coolant bypass valve. As it turns out, many other corolla, rav 4, and camry owners of the same generation (2020 and up) also receive the message and need to get the coolant bypass valves replaced around 30k-60k miles.
