What owners report

The contact stated that the vehicle was previously involved in two car crashes, where the vehicle rear-ended other vehicles due to the brakes failure. The air bags did not deploy. A police report was filed after the second crash, but the information was not available.
From the reports Iâve read since my accident last week, thousands of people have experienced similar or worse accidents from a Sudden Unintended Acceleration in their Toyota vehicle. Also, I read in an excellent well-researched and independent report t
The air bags did not deploy. There were no injuries and a police report was not filed. The vehicle was towed to an independent mechanic where it was in the process of being repaired. The dealer was not contacted. The manufacturer was made aware of the failure and did not assist.
Halfway through parallel parking, right rear of car by curb, foot lightly on brake, was about to shift to d and was looking around for any pedestrians short-cutting in front of car before shifting, when car accelerated, not stopping in spite of brake, until smashing into tree.
The dashboard currently displays multiple warning indicators: ABS light, Traction Control light, and the Brake System Warning light (Master Warning "!"). Symptoms: Mechanical Failure: The internal high-pressure accumulator is failing to hold pressure.
Last month, the engine light came on, so I took it to a dealership. They diagnosed the issue and provided the codes P0302 and P0304. After consulting multiple shops, all confirmed that coolant is leaking into the engine, which means I either need to repair the head gasket or replace the engine entirely.
8/2025 Car stalled on freeway. Went to dealer. They said nothing wrong. Then on a trip north, car stalled again on freeway. Went to the nearest dealer. They too said nothing wrong. This time same thing. There is a recall for the exact symptoms of the exact car yet they say the repair was done.
The contact stated that while driving approximately 35 MPH, the brake light, tire pressure, traction control, battery, and other warning lights were illuminated. While attempting to depress the brake pedal, there was more resistance than normal, making it difficult to slow the vehicle.
