Toyota Corolla Engine problems by year

I was driving the car and expressway. The car was making a sound. The car did not have an engine light on it. Also, the car just switched gears. I pulled over and II was driving the car and expressway. The car was making a sound. The car did not have a engine light on it. Also, the car just switched gears. I pulled over and I tried to park the car, but it wouldn't allow me to park the car. Which it is left in drive with the emergency brake still in place .and if you let the break down the car will roll . . I got it looked at and now they are saying it's the transmission, but it never had a light on to identify what was wrong with the car. There was no codes on the car.

schedule a service appointment at AutoNation Toyota Hayward for October 14, 2026, at 8:40 AM. I arrived before 8:37. At that time, I was told it would only take three hours to complete. The car hadn't moved at 11:37. At that time I asked when it could be completed. I was told there's no estimated completion time. So I've decided to leave. Why was my appointment set for 8:40 if nobody was free to deal with this until 11:37 ?

I am reporting a severe, recurring safety hazard on my 2020 Toyota Corolla. The vehicle suddenly displays 'Drive-Start Control Malfunction' and completely cuts off engine power in motion, leaving the car stranded in active traffic. This happened after accelerating from a STOP sign on a main avenue. This is an inherent manufacturing defect present since delivery. In total, this chronic electrical surge has burned through 6 batteries and 3 Engine Control Modules (ECMs) at different mileages. Within the first weeks...

What component or system failed or malfunctioned: complete slave cylinder failure resulting in loss of braking and ability to shift. Luckily I was traveling at a low rate of speed when this happened, but if this happens to anyone on the freeway or while turning against traffic for example they would have no control of their car and could be seriously injured. I took it to the dealership and they diagnosed it as a slave cylinder failure at only 70k miles. This is incredibly pre-mature. The vehicle has not been...

"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.

My Engine Maintenance light came on around 59,400 miles for my Coolest Control valve !! Needed it to be replaced! Light won't go off just had it serviced for an oil change before this started!!

I am reporting a severe safety defect regarding a failed engine coolant bypass valve on my 2022 Toyota Corolla Apex SE (VIN: [[redacted]], Mileage: 54,700). An authorized Toyota dealership has scanned the vehicle and confirmed active Diagnostic Trouble Code (DTC) P268115 ("Engine Coolant Bypass Valve Circuit Open"). This mechanical and electrical failure triggers an immediate dashboard warning and creates an imminent risk of sudden engine overheating, thermal engine damage, and catastrophic loss of motive power...

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. Toyota has acknowledged this issue in court but failed to do so at the customer level in my case. engine light came on at 97k and now I'm at 104k which is over that 100k mark. Issue is I've only take my car to Toyota for repairs. They have known about this but failed to repair or notify me...

While driving in the middle of active traffic, the vehicle experienced a sudden and dangerous loss of motive power. The first indication of a problem was the A/C abruptly blowing hot air. Immediately following this, the vehicle began violently shaking before the engine stalled completely. The low oil pressure warning light was triggered on the dashboard. Losing all acceleration in the middle of active traffic created an immediate, severe crash hazard. The engine failure occurred after a franchised dealer service department failed. They had said at the dealership that my oil was fine. They didn't even check it.

Notification spontaneously received as Engine Maintenance Required; Visit Your Dealer. Service appointment immediately scheduled for Toyota of Plano for the following day. My service advisor recommended replacing the coolant bypass valve, which amounted to a total bill of $745. My agent informed me of CSP 24TE04, however my service advisor didn't acknowledge any eligibility of VIN pertaining to it. Toyota Brand Engagement Center also did not report any eligibility of my VIN number for secondary coverage reimbursement despite it meeting the criteria exactly.

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". There is already a recall for many Toyota Corolla Sedans experiencing this issue of this bypass valve being defective, but because this is a hatchback, it is not part of the recall when it should be. There is already a recall for vehicles affected with this issue: T-SB-0112-24

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.
