2019 Toyota RAV4 Hybrid XSE with 42000 miles on it. Engine light with message came on. -??Malfunction in the electronic control of the engine, throttle or automatic transmission has been detected-??. Toyota dealership said it was Code P0128. Seems like this is prevalent in the RAV4 when checking forums and owner sites. Why is there not a Recall for this matter for my VIN number. Toyota has other -??engine coolant-?? recalls and I believe this one should be included! I am being charge almost 600$ for this repair!

Coolant Bypass Valve went out. Causes the car to overheat if coolant leaks from the valve. HVAC system will not properly work if valve is bad. This is a common problem and should be addressed.

"ENGINE MAINTENANCE REQUIRED, VISIT YOUR DEALER" Message came up on dash display. Took it to the dealership for diagnostic inspection. They informed me that the coolant bypass valve needed to be replaced. After much research, I found that this is a common occurance on newer model Rav 4s. If the component is not replaced, I was informed that it could cause overheating and other engine problems. Price to replace plus diagnostic check is around $650. I have read other complaints about this same issue on the NHTSA website. Will there be a recall issued on this component?

In my Rav4, I had a message pop up that said "Engine Maintenance Required" and it wouldn't go away. I couldn't get rid of it. So I took it to the dealership and they immediately said that I needed my engine coolant bypass valve replaced. They also said it has been a constant issue with other Rav4 vehicles, but there has not been a recall yet. So I paid $650 to get the valve replaced and the continuous message taken off.

Engine maintenance repair light came on and it ended up needing the coolant valve replaced. Cost over $700 out of pocket when part alone is less than $100. After research, this seems to be happening to many newer models of RAV4 when warranty is expired.

Engine Maintenance Required light on due to a faulty Coolant Bypass Valve. After doing research online, there are many 2019 and 2020 RAV4 that have been having this problem. The dealer said the same thing. Would like to put this on the record in hopes that a recall will happen in the future.

2019 RAV4 experienced a check engine light and was overheating due to a faulty Coolant Bypass Valve made by Toyota. If unchecked and not replaced it could cause catastrophic failure to engine due to overheating. Toyota charges between $600-1100 for replacement and it is not covered under warranty because Toyota claims it is not part of power train. Had to be replaced at dealer who explained that it is a common issue with this vehicle.
