Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Acceleration driving East on us rte. 50 at about 60 mph: Vehicle accelerated for no apparent reason. I nearly ran into the car ahead of me. This car is equipped with radar adaptive cruise control, which was engaged at the time. I turned off the cruise control in time to avoid a collision. Unintended acceleration has sporadically occurred, but it is usually fairly mild. This time it was so powerful that it felt like I had stomped on the accelerator; the engine roared and the car took off at full throttle. Thankfully I was traveling at the max distance of the cruise control. Acceleration was not caused by floor mats. I watched while the dealer service manager checked. Deceleration driving East on I-70: The car ahead of me signaled to exit the interstate and turned smoothly onto the exit ramp. As soon as he was out of my lane my car's cruise control locked on to the that of the exiting car and vigorously applied the brakes. Stepping on the accelerator did no good.

I was pulling into a convenience store in my 2014 Prius. As I was gliding in, I depressed the brake pedal and the car kept going. I continued to press the brake and the car started to accelerate. I could feel the surge of power. I was completely unable to stop the car and I ran into parking posts at the front of the store. All airbags were deployed. I got a cut on my forehead and was bleeding. An ambulance arrived and my husband drove me to the er afterwards and I received treatment. I was coming home from the gym at 9am in the morning. I have never been at fault in an auto accident before. I have a witness that said he heard a chirping sound coming from my brakes right before the crash. I have the pin drive from the car that a representative, supposedly from an outside source, that retrieved it. This is what Toyota used to conduct their "investigation" into the incident. They concluded that it was completely not their fault, not indicating how it could have happened. They are not going to help at all. Someone other than Toyota needs to investigate this problem before someone else gets killed. ( I filed a previous complaint this morning but realized I had entered the VIN number wrong. This is the same complaint with the correct VIN number.

I was coming home from the gym at 9 am I have never been at fault in an accident before. I have a witness that said he heard a chirping sound coming from the brakes before I crashed. Toyota completely denies there is anything wrong with the car, but gives no explanation as to how this could have occurred. They will not help at all. Someone is going to get seriously injured or killed. This needs to be investigated by someone other than Toyota.

While traveling in slippery conditions I attempted to navigate a right hand turn. The car began to slide while braking indicating possible snow buildup in front of tires. I attempted to accelerate out of the slide which is proper in front wheel drive vehicles. The cars dash lights lite up and the slide indicator started beeping. The car became completely unresponsive to the gas providing no power whatsoever. The car slid over the curb and crashed into a highway sign and finally came to rest.
