2021 Toyota Corolla Other Problems

Your check engine light comes on with a warning bell, and diagnostics show a coolant bypass valve malfunction. This appears to be a recurring issue affecting 2020-2021 models. The fix will likely involve inspecting and replacing the faulty coolant bypass valve.

-coolant bypass valve -it risked my safety by possibly destroying my perfectly good car -yes my toyota dealership confirmed the faulty coolant bypass (which many people have had this exact issue with these toyota models) -no -yes about a week before it was serviced

Data communication module activation failed message at start of car. It's loud and my baby gets woken up by this..

I was coming to a stop and the clutch slave master cylinder just sank to the floor and wouldn’t activate the clutch. There were no symptoms of the clutch failing or having trouble changing gears prior to its failure. It was inspected by the Toyota tech and he couldn’t give me a reason for its premature failure.

The horn has failed to work now for the second time. I first had this problem at approximately 97000 right before my warranty was up, and toyota had to replace the entire horn assembly they said that the wiring got wrapped up behind steering wheel and they weren't sure how . Now it started intermittently working the day I was going to let my daughter take her dmv drive test so she was not able to use my car it was sounding sick when I pressed it. Now it will not work at all . My car currently has 140k on it . Complete Safety hazard when someone pulls out of a parking space and you can't alert them to not hit your car! YOU PANIC!!!! . This is A Safety Issue!!!! And I have had no warning lights that came on, nor any messages on my system warning screen on my radio. I've checked all my fuses they are fine. Nobody should have to worry about replacing an 800$ horn assembly every 40k that's ridiculous i have never had a horn failure. I feel this needs to be investigated I may not be the only one with this problem. I think they should be required to fix something of this nature just as they should all air bag and seat belt issues . It SHOULD NEVER FAIL!!!!

I was sitting idle in my car. The two cars crashing icon came on even though I was in the parking lot doing nothing. There was also issues with the other indications where I would use the back arrow on my steering wheel to clear the issue and it would not clear. Seems unsafe and scary.

At 61,000 miles I got an engine maintenance required light. After doing research on the Internet, I see that many people with the corolla similar years have had this issue. It is an engine coolant bypass valve.

Coolant bypass valve needs replaced. Car states 'engine maintenance required visit dealer.'

After x amount of miles a random service light will come on that states “engine maintenance required, visit your dealer “. It’s nerve racking for your every day drivers.

A crack appeared in my windshield on the passenger side. Ther is no damage from a rock and we haven’t had extreme temperature changes. It is growing and will soon be on the drivers side.

The rear back up camera continues to adhered road salt and sand debris that blocks the camera's ability to project a clear view in the dashboard monitor every winter season here in upstate New York from early November through last snow in Spring (April-May). I addressed with Toyota office ( I 800-331-4331) at least four times and told to go back to the area Toyota dealer as I previously had done that previous 3 years. I get strange looks as to why their going to resolve this safety concern as the maintenance manual on page 240 of the owner's manual states on right top page,: "If dirt or foreign matter ( such as drooletsz,snow, mud etc.) is adhering to the camera, it cannot transmit a clear image. In this case, flush with a large quantity of water and wipe the camera lens clean with a soft and wet cloth." This cleaning procedure doesn't work in subfreezing temperatures and only causes the water to freeze to this area of the rear hatch area and to the floor or driveway! This is a serious safety flaw having to rely on a dirty camera monitor when backing up which every time I leave my single lane driveway going directly to the avenue I reside. Besides with water and wet soft cloth leaving road grit debris on the camera will further risk to scratching up the view lense cover! So where's the safe solution to this repeated issue every winter now for the 3rd year?

I was parked in my parking space I reversed into the space. I left the car running in park to dispose of trash. When I come back to my car to retrieve my cell phone and key out of the ignition. When the car turned off, the car began to roll down as my space is at a slight decline and the result of this was me bumping into a motorcycle who is parked directly across from my spot. I attempted to brake and I wasn’t able to steer as I had vehicles to my left and right and this happened in a distance of maybe 20-25 ft. The other party was notified no one was hurt but both my vehicle and his bike took damage. I have damage to my front grill because of this malfunction. This has never happened before but as this is a new car, this concerns me greatly and has been brought to Toyota’s attention. I wanted to file a complaint as I know others have my same vehicle and they may have had or might end up in the same situation as I was in. I believe it is the parking brake that was the issue.

Every thing is good

WHEN I PARKED MY CAR THE MORNING ON MARCH 22, THE TEMPERATURE WAS AROUND 50F. THERE WAS NO WINDSHIELD CRACK AT THIS TIME. WHEN I WENT TO GET MY CAR IN THE AFTERNOON ON MARCH 22, A FOOT LONG CRACK HAD FORMED ON MY WINDSHIELD. THE TEMPERATURE AT THIS TIME WAS AROUND 70F. HAD THIS HAPPENED WHILE I DROVE, IT WOULD HAD BEEN A SAFETY HAZARD. A WINDSHIELD SHOULD NOT CRACK THIS FAST. A FOOT LONG ON THE FIRST DAY? THE CAR WASN'T EVEN MOVING WHEN THIS HAPPENED. IMAGINE HOW FAST THE CRACK WOULD CRACK IF THE CAR WAS MOVING. THE CAR HAD LESS THAN 500 MILES AND WAS LESS THAN A MONTH OLD WHEN THIS OCCURRED.
