Air bags
53 reports12 crashes1 fire1 related recall
“On May 22, 2026, I got off work and started my 2021 Toyota Corolla LE when I noticed the SRS airbag warning light was on. The warning light has remained on ever since. I am concerned that my airbags may not function properly in the event of an accident. I recently contacted Toyota corporate because I learned about a possible airbag recall from 2024. Toyota opened a case under my name, but I was never notified about the recall. I would like this issue investigated to determine whether my vehicle has an unresolved safety defect related to the airbag system”

“"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”. 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”
Power train
19 reports
“The contact owns a 2021 Toyota Corolla. The contact stated that while driving in third gear, the vehicle failed to shift into a lower gear and became stuck in Neutral. The vehicle was towed to an independent mechanic, where it was diagnosed with a defective slave cylinder, which was replaced. The manufacturer was not notified of the failure. The failure mileage was 89,023.”
Visibility/wiper
15 reports
“During the lower interval settings, wipers will not work in proper order. Sometimes you may get three quick wipes and them the wipers will stop in middle of windshield for about 5-8 seconds. Sometimes the wipers are inconsistent with proper timing and will not properly work all the time.”
Seat belts
8 reports2 crashes
“Within a week of buying my vehicle in May of 2021 I went to Clearwater Toyota where I bought the vehicle from and complaining about the three seat belts in the back malfunctioning. When nobody is sitting in the backseat they sound off as if somebody is sitting there. I know that there is a recall on the front seat belt sensor doing this same issue for the Toyota Corollas but everyone I have spoken to that owns a 2021 Toyota Corolla complains about the back seats doing it as well the sensors misfire or sound off every hour as I'm driving at least once an hour. As an Uber Lyft driver I am concerned about my passengers in the backseat wearing the seat belts and the seat belt malfunctioning due to the sensors malfunctioning since I bought the vehicle in May of 2021. Any of the above questions I would have to stay unknown.”
