Engine coolant bypass valve malfunctioned at 34xxx miles, causing -??engine maintenance required-?? this could cause the engine to get too hot or not hot enough and affect the internal components of the engine. After speaking to others with the same model and even other models, it seems to be a ongoing issue for many people.

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.

I have been taking my Toyota to Sun Toyota for routine maintenance and inspections. Upon today-??s inspections they are claiming the battery looks like it leaked on the axial, some of the undercarriage components look broken and rusty. Possibly needing replacement. The overall car is less than 60k in mileage so that seems odd to me. I also brought the car in at 45k and they made no mention of these issues during that vehicle inspection. I asked about my brakes and braking issues. I do not slam on my brakes and the technician said I should stop braking too hard. There is noticeable wear now on them. I asked them to change them at the previous visit and they refused saying it did not need it. I am concerned for my safety and lack of care at this sun Toyota.

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.

When I was driving on the freeway on January 21, 2022, I had my iPhone X plugged into the car's infotainment system via USB to enable Apple CarPlay and navigate using Google Maps. In the middle of driving, the navigation system lost accuracy of my precise location. It continuously kept rerouting, as it believed that I had exited the freeway and was now on the side street. GPS precision is unreliable when the connected phone is not unlocked and on the Google Maps app (sometimes it works, sometimes it doesn't). This is obviously a safety hazard, since I have to exit the Google Maps app on my phone, reopen it, and reroute to the location so the software accurately picks up my location (luckily, the car has lane-trace assist). Another issue is when using Google Maps (an issue with all navigation app, really; here I use Google Maps as an example, but I've had an issue with all maps apps I use, including Apple Maps) navigation with Apple CarPlay and the iPhone locks itself or the driver exits the Google Maps app on the phone. Sometimes, when the phone locks itself from idle usage (as it should, since the driver is focusing on the road) or when the Google Maps app is exited (but not closed), the navigation interface on the car's infotainment system freezes. It shows the current location of the vehicle as stationary when it really should be moving. The intended functionality is the navigation software should continue running and updating as the car moves, regardless of whether the phone is locked or if the Google Maps app is only running in the background. This issue happens sporadically, but poses a significant risk of a collision, as it forces the driver to use their phone and reroute their navigation instead of paying attention to the road. Toyota needs to coordinate with Apple to address this issue on Apple CarPlay and subsequently release a software update to drivers.

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.

After bringing my 2021 Corolla into a certified mechanic that I personally trust is the most skilled and talented for Toyota brand, as a specialist for asian make vehicles. I was told that my unit was given a old battery despite the year of my vehicle. The safety of starting the engine was discovered 3 days ago. When I couldn't start the Car. I brought it to mountain view auto mechanics, in mountain view, CA. The mechanic I spoke with visually scans the engine and said that everything was not tampered with, but requires a replacement battery, by the Toyota dealership; any of the locations. Because the car is a 2021 it falls in the category of standard brand new warranty. A diagnostic fee has been said by Toyota of Stevens creek of the amounts of 230.00$ to find the issue. Even though I in with in warranty. I work at Quiktrak inc. as Field Inspector/authorized inspector my id# is CNP995 I perform inspection audits for vehicles and vessels all in the northern areas of California. I am complaining about my vehicle being un-safe for long term use, because of contraindications of how my car is. For the record. I have not modified any thing that would void my vehicles basic warrenty. Nor the CA emissions warenty

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.

1.experienced sudden acceleration problem at a signal light 2.to control sudden acceleration, need to push brakes harder than a non hybrid car 3.in the reverse direction, it goes too fast without pushing the gas, this may cause a crash missing extra tire and the accessories (jack, lug wrench, other tools etc) even though there is a slotted place holder there. (shame on Toyota for doing this, to order a new kit this will cost approx $1,500 per missing kit, if you were to order individually, this can potentially be a serious personal safety issue if you're in a bad neighborhood and waiting for tow truck vs quickly change the tire and leave) 4.cheap soft tires, got a screw within 2 months? called Toyota, towing is free, but you must pay for the flat repair or buy a new tire (about $250) every time there is flat as you do not have extra tire, jack, lug wrench. (this can be racketeering - shame on Toyota for doing this) 5.2nd car (2021 hybrid) came with the low brake fluid levels, close to the low/middle vs brand new car with new brakes, fluid level should be close to maximum. (shame on Toyota for doing this and playing cheap, besides safety issue) 6.to repair flat tire, the air pump and glue kit is a joke, this doesn't work - Toyota should provide non-flat able tires before this genius mickey-mouse invention. (shame on Toyota for doing this)

On 4 occasions, after engaging cruise control (65mph) the steering wheel went hard and it appeared that the wheel alignment was off and the vehicle veered left and it would create to small amount of torque on the steering wheel. Again, only when I engaged the cruise control. VIN: [xxx] (there is no "Y") (change "Y" to "T". sorry :-( information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
