车主怎么说
Drove car at reasonable low speeds (30-40mph) parked vehicle and noticed smell of something burning and light smoke. Opened hood and car was on fire. No mods, completely stock, low mileage. All services up to date. No reasonable explanation for sudden fire
To start, on [XXX], I was going through an intersection on a country road and my automatic emergency braking engaged for no reason. My car stopped despite no other vehicle or object being in my way or anywhere close to me.
Part is the coolant bypass valve. Toyota has been taken to court but dealership claims now that I’m over 100k miles I can’t do it. There was also a second part about 10 years but I wasn’t clear on the details of the outcome.
This Toyota Corolla hatchback is experiencing an issue where it is constantly giving an “ENGINE MAINTENANCE REQUIRED” light and when scanned, it says “coolant bypass valve malfunction”.
Notification spontaneously received as Engine Maintenance Required; Visit Your Dealer. Service appointment immediately scheduled for Toyota of Plano for the following day.
A message came on the screen saying “engine maintenance required” and it’s not going away. Upon doing a google search, there is a common failure in the cooling system for these cars reported by a lot of owners.
