Equipment Problems of Toyota Corolla - part 1

Windshield-visibility: description of safety defect & incident: I am reporting a severe, life-threatening factory manufacturing defect internal to the windshield glass of my 2026 Toyota Corolla w approximately 1200 miles. I noticed this defect shortly after taking possession of the car, although the daytime sun was higher and I though that windshields might be made differently. It was a confusing situation. Under specific lighting conditions, the defect caused catastrophic light scattering, resulting in an instantaneous and complete loss of forward driving visibility. On 9/22/26, while driving up a hill at approximately 6:30 pm (sun low during sunset), the vehicle reached the crest of the hill where the sun struck the windshield directly. The defect caused the entire windshield to instantaneously "white out," blasting intensely scattered light across my entire field of vision. I was completely unable to see the road, and there was oncoming traffic, I couldn't see the lane markings either. I immediately and blindly pulled to the shoulder, and after a few minutes (to adjust my eyes back to normal) I inched forward until the angle of the sun shifted and I was able to see again. During nighttime driving, the defect distorts light from oncoming vehicles - headlights are bent and stretched into blinding, very large "cross" shapes and starburst halos that blur my vision and make nighttime driving also dangerous. I attempted to clean the glass and even tried a little scrape with no effect. Where and at what angle the daylight shines on the windshield determines the severity of the effect. Oncoming lights at night are worse with bright led's. I request that the NHTSA investigate before this defect causes a fatal collision. The car was delivered to the dealership first thing the following morning on 9/23/26 and the dealership shop manager witnessed the defect in the morning light. I offered to take a drive but the shop manager declined. The car is available for inspection.

The air bag light stays on at all times when there is nothing on the passengers seat. This has stayed on for the past two weeks. I am afraid that the airbag might fail and cause an injury.

The defrost no longer works. When I put on defrost it doesn't blow out of the defrost causing me not to be able to see out of my windshield. I have found other people online with this same issue. My heat and air conditioner work fine.

My door actuators are going out on all my doors started with the driver door then the passenger rear door and now my driver rear door. This poses serious safety concerns, for example when class vehicles are involved in vehicular accidents because the occupants may become entrapped when the door actuator defect prevents an occupant from unlocking the doors. Furthermore, this defect jeopardizes the safety of vehicle occupants given that not all doors are capable of being manually unlocked from the exterior. Also another thing I would like to add is that when I try to unlock the doors my only two working doors are my passenger front and back driver rear door but like I said it is starting to go out but I have to unlock them first then I have to use the key to the driver door just to get in cause if I do it the other way the car alarm will go off.

I pulled into xxx drive way at 6:53pm xxx. By 7:12 pm we were on the phone with 911. My car alarm when off. I went over to my car. It was smoking had a bad smell it smelt like it was about to explode. It wouldn’t let me unlock the car. Finally after 5 minutes it finally unlocked there is literal flames on the driver side dash and floor board. We used a fire extinguisher it was still smoking so we put water on it. When the fire department finally showed up the dash was still 182 degrees. They used their high water power fire extinguisher. The battery was also unplugs before the fire was completely out. And state farm called a tow truck to take it to pohanka in salisbury MD.

Purchase car at the end of July 2 weeks later heard a not a rattling sound while driving the vehicle. Took the vehicle for a service appointment at the dealership. I purchased it from. I was told by service as well as the sales manager that the rattling sound was found in both my car and another car with zero mileage. The sales manager stated I would have to put up with the rattling and the rattling has gotten progressively worse. The sales manager stated he could not help me any further. I bought the new car and traded in my old one that had a rattling sound and now drive a new car that rattles and that is what I told the sales manager and he stated I would have to wait to turn it in. The sales manager then stated that he stated that is the way that the car drives and that I’m sensitive to the noise. I then told him that the service man stated that something was wrong with the car and that they could not pinpoint it and that the car came that way from the manufacturer, and that I would have to wait until something went wrong with the car in order for them to be able to help me. The rattling sound is loud and the sales manager and my husband drove the car together and he stated that it was loud. That it could possibly be the transmission and if something were to go wrong while I’m driving and it’s a defect, we would have to wait until something happened. I am very displeased with the outcome of me purchasing this new car from this dealership and there, laza fair attitude towards my safety. The car has an obvious problem and I feel the car dealership and Toyota sold me a car that could potentially either breakdown or cause me harm.

While driving in the middle of active traffic, the vehicle experienced a sudden and dangerous loss of motive power. The first indication of a problem was the a/c abruptly blowing hot air. Immediately following this, the vehicle began violently shaking before the engine stalled completely. The low oil pressure warning light was triggered on the dashboard. Losing all acceleration in the middle of active traffic created an immediate, severe crash hazard. The engine failure occurred after a franchised dealer service department failed. They had said at the dealership that my oil was fine. They didn’t even check it.

Vehicle emissions out of the dashboard defroster vents deposit a sticky, chemical film onto the inside front windshield, causing severe driver vision impairment. The chemical vapor triggers immediate respiratory irritation and dizziness, presenting an imminent risk of a motor vehicle crash. Defect / nonconformity: the vehicle suffers from a severe hvac or interior component material failure causing toxic off-gassing. An official Toyota fts report (ro #116504) documented dangerous tvoc levels of 9. 455 mg inside the vehicle. The manufacturing defect substantially impairs the safety, use, and commercial value of the vehicle. I did not have car seats in trunk, the time completed on report is changed, they will no longer inspect car. Specialist (fts) report explicitly logs tvoc levels at 9. 455 mg (3 ppm) inside the cabin. The film on my front windows is not coming from the trunk this is a known hazard . Literally told you.

I also wanted to add the mold. . From the hour test was performed on this car. Ac in high flow. Within 12 hrs growth appears.

The glass on the instrument panel has an extreme glare in the sun. I have tinted all my windows including the windshield, but the issue persists. The hood on the instrument panel needs to be longer or the glass needs to be non glare. There is nothing on the market that will fix this issue.

I have mcas/ cirs this new car triggered chest pain, muscle weakness, swelling, etc fts report confirmed high off gassing. I'm in 3 mast cell stabalizers a day. I'm w out a car I put down 3500 a month ago. They left me, knowing all this. I'm 9 miles from a bus stop, from shopping, can't make money w out a car. 40 min from drs. I already have lung nodules. Single mom, just want a safe reliable car odi xxx, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My brand-new 2026 Toyota Corolla le is venting toxic chemical, burning plastic, and acetone-like fumes directly through the dashboard hvac vents and interior materials. Exposure to the cabin air causes immediate, severe systemic injury, including acute respiratory distress, throat and vocal cord inflammation resulting in a lost voice, uncontrollable sweating, and severe neurological muscle weakness. I have a critical pre-existing medical condition consisting of two lung nodules, making this chemical inhalation an immediate, life-threatening hazard to my health. This exposure has previously left me physically incapacitated for five days. The manufacturer (Toyota motor north America) has been formally notified of the defect and my documented medical injuries. However, the manufacturer is refusing to provide emergency alternative transportation or safe loaner transport and is delaying the vehicle safety inspection for a full week (until June 29). The vehicle is currently parked and completely undriveable due to the active chemical or thermal hazard it presents to vehicle occupants.

When I purchase this vehicle in 2022 the emergency parking break does make a noise when going on d or parking but it wasn't loud about a week ago, and today is June 10th, it started making a loud noise and the Toyota dealership in lebanon PA does not want to fix it.

System or component that failed: heating, ventilation, and air conditioning (hvac) / climate control system. Description of incident: the vehicle's hvac system emits a severe, persistent chemical odor / volatile organic compound (voc) smell directly into the passenger cabin. Nail polish remover, burning plastic after driving forth 20 min, was not addressed. This toxic-smelling odor causes immediate physical discomfort, chest pain, neck stiffness, including headaches and respiratory irritation while driving, creating a driver distraction and safety hazard. Dealer status: the vehicle was taken to a Toyota dealership on June 13, July 29th, refused any further investigation. Under warrantybut the defect could not be permanently resolved by the service center. Now seeing the chip in car was messed with after getting it towed back.

The vehicle's infotainment system, specifically when utilizing android auto, is subject to recurrent, unprompted ui freezes and interface crashes while the vehicle is in motion. These malfunctions are induced by a persistent server-side enterprise management policy ('disabled_by_admin_policy') applied to the connected mobile device. The resulting software-induced failures cause the vehicle's display to freeze or become unresponsive, creating a severe and unpredictable distraction to the driver while operating the vehicle. Despite documenting these incidents, the manufacturer’s support team has refused to remediate the software conflict, instead instructing the user to power down the device during operation. The interface failure persists across multiple driving sessions, presenting a continuous risk of operator distraction and loss of critical navigation/safety data.

Replace heater control valve - diagnostic code p2681 indicates an internal electrical failure within the heater control valve assembly, a condition commonly seen on Toyota vehicles. Testing showed the electrical portion of the valve is open and no longer maintaining proper circuit continuity, requiring replacement of the heater control valve assembly.

This complaint is not about a specific incident, but about excessively-brilliant (blinding) headlights. In the flow of traffic, the blinded drivers far outnumber the vehicle using blinding headlights. The area those headlights cover spreads out so wide, the blinded driver is not able to see the side of the road. Insurance companies may say this problem does not cause accidents; but, I believe that is because many drivers do not dare risk driving at night. Excessively-brilliant, blinding, headlights should be banned and recalled. Those headlights are a terrible safety concern and should have been banned years ago.

Airbags did not deploy in at crash where we were hit head on and car is totaled. I do not know the rate of speed the gentleman was driving, but the speed limit in the area was 45 mph and the gentleman ran the red light and hit us as we were waiting to make a left turn. Every responder, police, wrecker, medical personnel, and tow yard remarked that the air bags should have deployed after witnessing the extensive damage. Car is currently in tow yard. Insurance has offered payout but we have not accepted as of today. I keep trying to speak with Toyota but the wait times are extensive.

The "engine maintenance required" signal keeps coming on when I start my vehicle and the a/c is on. It is a fault of a code for the bypass coolant valve, which is in perfect condition. I just took my vehicle for the regular maintenance over the weekend. The regular "maintenance required" signal went off after picking it up. After an hour or two, the "engine" signal reappeared. This is a common issue in the Toyota's and I shouldn't have to be financially responsible for a faulty code.

Car shows the below message when a/c is turned engine maintenance required visit your dealer.

I received a "do not drive" recall for my vehicle in the mail because of defective air bags. The recall letter claimed that there have been twenty-eight confirmed deaths in relation to this recall. I entered priority Toyota of chesapeake, va to address the issue. That was on Monday, April 6th, 2026. Even though there was a "do not drive" order on the recall, priority Toyota of chesapeake refused to give me a loaner vehicle. It is now Monday, April 13th, and priority Toyota of chesapeake has claimed that they are still waiting on an email to begin repairing the vehicle, which I need for transport. This is a formal complaint that priority Toyota of chesapeake, va has failed to repair the recalls to the vehicle in a timely manner.

After the car is warmed up after driving for a few minutes, I stop at a red light and the car's rpms dip from 700 rpm idle to 500ish rpm, when it starts shaking. Then the rpm would go back up to 700 rpm. This only ever happens when in drive and foot is on the brake. If I shift to neutral or park it goes away and idles normally at 700 or higher rpm. A/c on or off has no effect on this. Oddly enough, if I turn on the drls or full headlights, the rpms don't dip. I feel like it will only be a matter of time before the rpm will dip low enough to the point where the engine will die on me. This is a safety concern. No check engine lights. I have cleaned the maf sensor, changed engine air filter, cleaned throttle body, changed pcv valve, cleaned injectors, run fuel injector cleaner through the gas tank, replaced my engine mounts. Still, the issue persists. I have no idea why.

The factory-applied super white (paint code 040) paint on my vehicle has peeled down to bare metal on multiple exterior body panels. The peeling is not the result of any collision damage, scratches, or external trauma — it is consistent with the known factory paint adhesion defect that Toyota itself acknowledged through customer support program zkg, which covered this exact vehicle model, year, and paint color. Toyota's own program documentation states the defect occurs when sunlight degrades adhesion between the factory paint primer coat and the base metal electrodeposition layer. With paint peeled to bare metal, the affected panels are now exposed to moisture and the elements, creating a risk of structural rust and corrosion over time. I purchased this vehicle used in 2023 and was never notified of the customer support program. By the time I discovered the program existed, the coverage had expired. Toyota has declined to provide any assistance. Toyota acknowledged this as a manufacturing defect affecting approximately 1. 74 million vehicles under program zkg. Owners of 2016 Corollas who purchased their vehicles used were not adequately notified, and coverage has now lapsed for recently expired vehicles despite the defect being identical to those Toyota previously covered. I am requesting that NHTSA investigate whether Toyota's customer support program zkg adequately covered all affected vehicles and owners, and whether an expanded or extended remedy is warranted.

Coolant water control valve short circuit. Causes dealer message that won't clear and dealer wants $600 to replace a $30 part. Part is extremely difficult to get to and should not be a wear item.

Unknown—he only performed the inspection, as I am a lyft driver and my account was suspended due to a recall issued by the NHTSA.

While I was driving during the evening time on March 7, 2026, my rear passenger window exploded, for seemingly no reason, as I stepped out of the vehicle I noticed no one around and I called the police and I was given a report number which is 26–01784 and that is with the westminster police department!.

My 2010 Toyota Corolla is experiencing progressive paint failure due to a known manufacturer defect involving factory-applied blizzard pearl or super white paint. The affected component is the factory paint system, specifically the adhesion between the topcoat and primer, which is failing and causing the paint to peel off in sheets from exterior body panels. The defective paint is available for inspection upon request. This condition creates a potential safety concern, as sections of paint may detach while the vehicle is in motion, creating debris that could pose a hazard to surrounding motorists. In addition, exposed underlying surfaces may become more susceptible to corrosion over time, which could affect the integrity of exterior body panels. The issue was previously confirmed by an authorized dealership during inspections conducted under the manufacturer’s customer support program for paint peeling on vehicles equipped with blizzard pearl or super white paint. During the active coverage period, only certain visibly affected panels were refinished, while other factory-painted panels were left untreated. Since the program has expired, the previously untreated panels are now exhibiting the same paint peeling and failure that the program was intended to address. The paint deterioration developed gradually over time and was not the result of external damage. No warning lamps or messages were present prior to the failure.

Today I noticed that both of my door front locks passenger and driver side do not even actuate to have the door locked and unlocked by key of by the alarm. They completely stopped working. Even I contacted Toyota corporate several times about this issue (800) 331-4331 and got ignored. This is a safety issue that needs to be addressed immediately. This is a safety concern for me and family.

I purchased a vehicle that was represented as having approximately 92,000 miles. I have since discovered the actual mileage is approximately 260,000 miles, which indicates odometer tampering. This is a violation of both federal and California law. I have documentation supporting this claim.

“engine maintenance required, see your dealer” light comes on the dashboard with a warning bell. Did a diagnostic test, and the code is the coolant bypass valve malfunction. This seems to be a common issue among 2020-2021 models. This has been inspected by professional mechanics.

On the morning of January 7, 2026, while I was on my way to work, I experienced a dangerous incident involving my vehicle. As I arrived at the first stop on the street, I suddenly heard a loud explosion. Immediately afterward, pieces of glass began falling onto my windshield. I pulled over and exited the vehicle to assess the situation. Upon inspection, I discovered that the sunroof of my car had completely shattered. Glass was scattered across the roof, windshield, and interior of the vehicle. Prior to the explosion, there were no visible signs of damage to the sunroof. The incident occurred without warning and posed a serious safety risk. I am submitting this complaint to formally document what happened and to request that the matter be investigated and addressed appropriately.

The paint on my 2013 Toyota Corolla, super white (040), is peeling extensively down to the primer on the roof, hood, trunk, and door frames and pillar areas. Toyota previously acknowledged this issue as a manufacturing defect affecting 2008–2017 Corollas and issued a warranty enhancement program to address it. My vehicle’s claim for assistance was denied solely due to the program expiration, even though the defect persists. The peeling is widespread, severe, and not consistent with normal wear or environmental exposure. The metal surfaces are exposed, increasing the risk of corrosion. I am submitting this complaint to document the defect and Toyota’s refusal to assist despite prior acknowledgment.

I traded in my 2022 Corolla le for a 2026 Corolla se and I got my car on December 19th, 2025 and ever since I got it, the wireless charger hasn’t been working not once. I turn it on, it charges and the light is green and after a few seconds, it stops charging and flashes orange repeatedly. I tried it with different phones, without a case, and brought it to the dealership where they replaced the wireless charger but the issue continued with the new charger, so they put back the original one. The dealership told me it’s a defect issue and that other people had similar issues.
