What component or system failed or malfunctioned, and is it available for inspection upon request? The HVAC system, specifically the electric A/C compressor, has failed. The system produces a loud grinding/buzzing noise and has been diagnosed by authorized Toyota dealerships as requiring full compressor replacement. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? This failure directly impacts the vehicle’s defrost system, which is critical for maintaining windshield visibility. Reduced or failed defrost capability creates a safety hazard by impairing visibility while driving, increasing the risk of an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue has been confirmed by multiple authorized Toyota dealerships, including Sheehy Toyota and Mike Calvert Toyota. Both independently diagnosed a failed A/C compressor requiring replacement. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The issue has been escalated to Toyota Corporate, and a case manager has reviewed the dealership findings. Documentation has been submitted to Toyota for warranty and goodwill consideration. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. A grinding/buzzing noise began when the A/C system was activated and was formally reported to Sheehy Toyota on October 27, 2025, while the vehicle was under warranty.

I am very concerned about potential accidents for my self and others driving this vehicle. I have multiple close call accidents because the left view mirror does't have proper view to see cars on left side especially if they are close. The way seat and the side of the vehicle is shaped its very hard to still see manually with head turned to the left rear side. The mirror or the shape or position needs to be changed for safety to prevent accidents.

Steering system, potentially related to electric power steering (EPS) or driver-assist systems (lane keeping or steering assist). While completing a routine right-hand turn, my husband began to straighten the steering wheel when the steering system suddenly and sharply turned further right without any driver input. This caused the vehicle to strike a curb, damaging both passenger-side wheels and the front tire. There were no warning lights or indicators, and road and weather conditions were normal. The uncommanded steering input appeared to come from the vehicle itself. The incident resulted in loss of directional control and could have been severe had another vehicle, pedestrian, or cyclist been present. This behavior reflects a serious and unexpected failure in the steering or driver-assist system, posing a direct threat to driver and public safety. I reported the incident to my local Toyota dealership. I have since signed Toyota’s EDR (Event Data Recorder) consent form, and an official inspection has occurred but they haven't provided detail. They also did not make me aware the inspection was taking place and did it without coordination. They have not confirmed that this has happened before. A similar, though less severe, issue occurred previously while I was driving on the highway. As I approached a merging lane to my right, the car suddenly pulled sharply to the right, seemingly misinterpreting the lane markings or misjudging its position. There were no vehicles next to me at the time, and I was able to regain control. While it did not result in a collision, it was alarming and appears to have been a driver-assist or steering control malfunction.
