ELECTRICAL SYSTEM,ENGINE — Filed 10/08/2025

"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

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.

On December 12, 2025, I was in a head on car accident in my 2021 Toyota Corolla nightshade. I was slammed into the steering wheel which caused injury. My car has over $14,000 worth of damage to the front yet my airbags did not deploy. I have taken my car to Toyota several times over the past few years and every time I’ve asked about a remedy for this recall I’ve been told there is no remedy as early as June or July 2025 I had to bring my car in for a manufacturer defect with the engine that Toyota fixed for free. I asked them about the recall on the airbags. They again told me there was no remedy.

My vehicle was backed into while ì was inside of it in a parking lot. Due to my horn failing., I was unable to alert the other driver to see me. The clock spring is what failed the first time at 95k they replaced it. I'm now at 147k and it failed again . Now I'm discovering that if it does not work, there's an electrical circuit failure and that the airbag will not deploy if I get in an accident. This is a serious safety issue and I feel Toyota should be responsible for it for the life of the vehicle . A horn should never go out. Especially if it not working will keep my air bag from functioning properly . 850 out of my pocket is way steep. The replacement part lasted half as long as the original part did when I bought the car that to me seems like a faulty part this should be obvious and they should just fix the problem cuz I might have to just consult an attorney should they choose not to. The attached photo shows what happens when you can't beep your horn at somebody who's about to back into your car !!! my car still has not turned on any kind of warning lamp for the airbag or any kind of malfunction light, no warnings on my radio. I have noticed that my Lane departure warning seems to work intermittently along with the automatic high beams that like to flash my high beams in people's face for some unapparent reason which also seems like a safety issue. If I had to take my car to an inspection station it would not pass an inspection due to the horn not working ! You cannot take your child to the Department of Motor Vehicles and let them take their drive test if your horn does not work ! which happened to be my case !! Very disappointing to say the least especially when you've paid $30,000 for a car.

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.

STEERING,AIR BAGS,SEATS — Filed 11/07/2022

I was rear ended. During the impact, which was enough to accelerate my vehicle from 9 mph to 36 mph, the steering wheel came completely off of the car and hit me in the head. The steering wheel was in the back seat immediately following the impact and my vehicle was traveling at 36 mph with no way to steer out control it and no airbags in front of me in case of a secondary collision. This happened on a busy interstate with dozens of drivers endangered by my out of control vehicle. Traffic had slowed for construction and it was a miracle I wasn't further injured or caused injury to anyone else. Toyota sent an inspector to look over the vehicle, and it may still be available on the wrecker lot.

EXTERIOR LIGHTING — Filed 11/06/2021

Headlights are defective. There is a "V" shaped dark spot in the headlights of the vehicle when on low beam. The significant unlit "V" shaped area does not allow the driver to see objects in the roadway which come up on a driver rather quickly, resulting in collisions. Toyota is aware of the defect, but will not act on it. Toyota Claim # 220811002276. There have been two collisions involving items in the roadway due to this headlight defect. Total out of pocket costs on the damage have been in excess of $1,500.

WHEELS,SERVICE BRAKES — Filed 12/13/2021

Recently my car was in an accident involving 2 other vehicles. An SUV in front of me rear-ended someone and then I rear-ended the SUV. We were in heavy traffic at a major intersection and were stopped at a red light. The light turned green and we began to move. We were accelerating from a stop and were maybe approaching 10 -15 mph. Traffic started to back up at the next light and so the first car stopped suddenly so as not to block the intersection. Then the driver in front of me crashed into that car. He was on his phone, not looking, and didn't have time to brake. I was about 2-3 car lengths behind when he came to a complete stop. I was also still accelerating, as were most cars, since the light had just turned green. As soon as the vehicle in front of me hit the other car and stopped moving, I immediately applied my brakes. Based on the distance I believe I should have been able to stop. I remember thinking there was plenty of room. Except that the ABS came on and, instead of stopping my car before hitting the object in front of me (because the car is also capable of doing that), it just continued to let my car slide right into the back of the vehicle in front of me. I was then "at fault" according to my insurance company despite my explanation of the details. This led to a $500 deductible for repairs and an increase in my insurance rate. I honestly believe that the ABS should not have activated in that situation. If the car is able to recognize and even stop for objects in front of it, why would it let me slide into another car? I've had similar situations with my other cars in the past and they always stopped quickly, often avoiding this very situation. To summarize, I feel that the antilock brake system in my car failed to act in a safe and appropriate manner, thus causing an increased risk of damage or injury to the vehicle and passengers. In my case it resulted in damage to my car and a lot of extra money to cover those damages. Thank you

While driving the vehicle the brake hold system was activated at a red light. While proceeding through the light within (about) 5 minutes the vehicle indicated a brake hold malfunction. An odor of smoke was also present, at that point I turned off the vehicle and inspected the origin; the trunk. Upon opening the trunk the right side had a sizeable fire growing towards my assets. Police did arrive on scene, an adjuster has examined the damages, however this has not seemed to be replicated. I believe the risks associated with this incident are quite evident. There was no collision.

ELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE — Filed 01/16/2021

AFTER PURCHASING MY COROLLA MY CAR POWERED DOWN. I TOOK IT BACK TO THE DEALERSHIP AND THEY CHECKED IT AND STATED THERE WAS NOTHING WRONG WITH IT. THIS WAS IN NOVEMBER 2020. ON 1/16/2021 I WAS DRIVING ON A HIGHWAY AND THE SAME THING HAPPENED, EVERYTHING JUST POWERED DOWN. I WAS FORTUNATE ENOUGH TO GET THE VEHICLE OFF THE ROAD AND CALLED THE DEALERSHIP. THIS WAS AROUND 6:00PM. I THEN CALLED MY FAMILY AND TOLD THEM WHERE I WAS AND WHAT HAPPENED. A PASSERBY STOPPED TO ASSIST ME AND GOT MY CAR RUNNING BY JUMPING IT OFF. AN HOUR LATER I WAS SITTING IN A PRIVATE DRIVE WAITING ON TRAFFIC TO PASS BEFORE PULLING OUT. THE NEXT THING I KNOW I WAS HIT BY ANOTHER VEHICLE. THE VEHICLE THAT HIT ME THEN WENT OVER TO THE OTHER LANE AND SIDESWIPED A TRUCK THAT HAD A LOW BOY TRAILER ATTACHED TO IT. IT IS MY UNDERSTANDING IS THAT WHEN THE TRUCK HIT THE OTHER TRUCK AFTER HITTING ME THAT IS WHEN THE 3 PEOPLE IN THE TRUCK WERE KILLED. TWO OF THE PEOPLE WERE EJECTED AND THE OTHER PARTIALLY EJECTED. THE PEOPLE IN THE 2ND TRUCK TOLD POLICE THAT I FAILED TO YIELD THE RIGHT OF WAY. THEY NEVER ASKED ME WHAT HAPPENED AND TOOK THE OTHER DRIVERS WORD AT WHAT HAPPENED. THERE WERE NO SKID MARKS FROM EITHER TRUCK ON THE ROADWAY. IF I WAS PULLING OUT I AM SURE THERE WOULD BE SKID MARKS.*DT*JB
