2026 Toyota Corolla problems

Filed Oct 16, 2026 · Tires · MO

This 2026 Toyota Corolla equipped with Dunlop Enasave 01 A/S size 205/55R16 tires has experienced three (3) catastrophic tire sidewall failures/blowouts in 13 months, despite full tread depth remaining. Two of these blowouts occurred within the last 30 days alone. Repeated sudden sidewall blowouts create a severe, life-threatening risk of loss of vehicle control at highway speeds. Dealer service departments have repeatedly replaced failed tires without diagnosing or resolving underlying suspension clearance, wheel alignment geometry, or mechanical defects causing these recurring structural failures. During an October 14, 2026 service visit, dealership staff refused to answer technical safety questions and withheld the failed tire evidence from inspection. Toyota Corporate Case # 261012001478 is open regarding these ongoing safety hazards and potential vehicle defect.

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 federal safety agency 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.

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.

I own a 2026 Toyota Corolla purchased in November 2025. The recurring problems began on December 8, 2025, when multiple warning lights appeared on the dashboard along with the message “System Malfunction – Visit Your Dealer.” The warning indicators involved several vehicle safety and driver-assistance systems. The vehicle was taken to an authorized Toyota dealership for inspection and repair. On June 16, 2026, the vehicle experienced another serious malfunction, including a “Transmission System Malfunction” warning. The electrical and operational problems continued despite dealership visits and repairs. The battery was also replaced, but this did not permanently resolve the recurring failures. During a later incident while the vehicle was being driven, multiple warning lights appeared and the vehicle lost power or shut off. There was no crash or injury, but the unexpected malfunction while driving created a serious risk to the driver, passengers, and other motorists. The dealership has also addressed an issue involving the shift lever position sensor and corrosion or water intrusion. I do not know the exact component responsible for all of these failures. However, the problems have occurred repeatedly since December 2025 despite multiple dealership visits. Toyota was notified and corporate Case No. 260630000224 was opened. I have not received a permanent explanation or resolution, and I am concerned that the vehicle could unexpectedly malfunction or shut off again while being driven.

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.

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.
