Error message that said 'drive start control malfunction. Took 6 mos and numerous attempts to resolve. Replaced numerous parts including the fuel pump because the plastic it's made out of was just disintegrating and and cracking. This has cost thousands of dollars in parts and labor. Also getting a msg on info screen 'connected device not supported' now. Apparently toyota did an update and there was a bug in the program yet I have to pay to fix their error to the dcm.

The slave cylinder failed l3aving me stranded in a parking lot. Luckily I wasnt driving down the highway as the slave cylinder is also part of the brake system they use the shared brake fluid reservoir. This is a very common problem and is a 4k plus cost to fix. Not including the time that has to go into fighting the warranty companies and dealers.

I have a 2019 Toyota Corolla Hatchback. The problems started on July 21st, 2025. While driving my 2019 Toyota Corolla Hatchback, I noted white exhaust smoke, even after the engine was warm. One week prior, I had filled the coolant reservoir, but when I checked it, the coolant was almost gone again. There were no visible leaks or puddles under the car. I refilled the coolant, but within days the car began shaking severely upon startup and emitted a coolant-burning smell. 5…

I got a “Engine Maintenance Required” warning message. I check with the dealer and upon diagnosis told me about a faulty coolant bypass valve which is a common problem for Toyota RAV4 and Corolla. The Toyota Mechanic mentioned that this should have been a recall issue. The cost to repair was unbelievable considering it will take only a short time to do. BOught the parts and will have it installed somewhere where the labor is cheaper. Since it is a common problem, the…

The coolant bypass valve failed in my car causing “engine maintenance required” message but no CEL code. Took it to the dealership where they determined failed component and replaced it. The car only had about 71,000 miles and with a engine cooling system failure it could potentially cause further damage.

The alert for the Bypass Coolant Valve came on and cost $800 to replace. As this is a common issue across multiple Toyota models, this should be a recall.

At around 36,500 miles, my Toyota Corolla began experiencing issues with the coolant bypass valve, leading to engine overheating. This malfunction has significantly impacted my ability to drive safely, as the vehicle displays a notification every five seconds, obstructing my view of the digital speedometer and making it difficult to accurately monitor my speed. The issue was not indicated by a check engine light but a persistent "Engine Maintenance Required" message. This…
