On three occasions this car was parked in an attached garage and remained running when parked resulting in potential CO exposure. This is a known hazard which NHTSA is aware of in cars with keyless start system in hybrid vehicles. Toyota is well aware of this issue (first acknowledged death in 2016 was in a Toyota Avalon) and was supposed to equip 2020 models with auto shutoff [XXX] I thought my 2020 Hybrid Corolla had this feature when purchased, but it does not. Toyota has not responded to multiple requests to retrofit my vehicle. This is a serious safety issue with many CO deaths reported. Its my understanding this will be required soon of new vehicles but its important that all existing hybrid vehicles be required to be retrofitted with auto shutoff to prevent continuing deaths.

Issue with unlocked driver's door after the collision reported on 6/25/23 # 11528724 Additional concern: After the accident, my car engine was not turned off automatically; even after automatic speaker announced collision and that 911 was informed. After I got out of the car ( # 1152874) I was standing by the car, drivers door I left opened and at one point I realized that my car was still running ( Gear shift was left in P). I manually switched off the car and I removed the key from ignition.

Just bought a used 20 Corolla SE and put less then 500 miles on it and got a "maintenance required return to dealer" notification on the dash and a warning message in my information screen via infotainment system. Dealer said they got nothing via a scan. The issue is the Coolant Bypass Valve. I reset the light on the dash and restarted my car with air off and it did not come back on. The second you turn on the air (the A/C in particular) the light immediately popped back on along with a new warning message. I've looked around and there's literally THOUSANDS of people reporting the same issue all on vehicles between 15k and 100k miles. The dealers also charge at least $600-$1100 to remedy this all too common issue as they will tell you it is not covered under warranty. I'm unsure of what promised damage to the vehicle could be but I know for a fact it's not nothing. Everyone is dumbstruck with how many people have this issue and there is still no Recall on this clearly terribly made Coolant Bypass Valve. It seems to apply of us that this is just a cash grab for Toyota

As a driver I was involved in frontal collision with my Toyota Corolla LE 2020 properly serviced. ([XXX]) . Air bags were deployed followed by smoky air that made me difficult to breathe. I opened the windows, but I could not open the door to get out; it was locked. A passer -by could not open the door from the outside either. He told me to move gear shift to P; I did that and he was able to open the door and I got out. There was on loud automatic message informing about collision…. Certain safety steps must be automatically activated after collision. I am very surprise to experience that the driver’s door could not be opened after collision from inside or outside. I had to move gear shift from D to P myself for the door to be opened. I could not breathe properly inside the car even with open windows with air bags deployed. The door should be automatically unlocked after the collision. Driver may be unconscious, the car is in the fire or may be nobody to help the driver.

I was driving on the road and I heard something like an explosion, I turned the emergency lights on and stopped to find out what had happened. I saw the sunroof completely broken, fortunately I didn’t get hurt but I got so scared and I don’t know if I will feel comfortable driving my car again.
