   "Engine maintenance required" light is coming up constantly, only when i turn on the AC and doesn't let me view my dash at all. Ive determined it's the Engine coolant bypass valve. Many models have had this same exact issue and there needs to be a recall/repair at no cost to the owners.

   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”.

5. Filed Jun 15, 2026CAWheels & Tires

   Over the past year and a half I’ve had to deal with unknown reasons for at least 13 tire problems. And one of those problems was a complete blow out on the highway.

I called the dealership and they said they don’t do that (meaning they don’t provide the car with a spare). I was very confused and stressed. I felt played and wasn’t made to feel confident in this purchase. That…
