Sudden maximum acceleration accompanied by brake failure, without warnings, occurred on my 2002 Toyota Tundra 4.7L V8 causing loss of control of the vehicle, which ended in a rollover crash, resulting in total loss of the vehicle and injury to me. While departing a 25 mph zone (sign read "END 25 SPEED LIMIT") on a relatively straight section of the road, I very gently accelerated from 20 mph to 30 mph. As soon as the vehicle reached 30 mph, sudden maximum acceleration occurred. Taking my foot off of the gas pedal, first I verified that the gas pedal was not stuck or blocked, but the gas pedal was in the fully up position. I then pressed the brake pedal very hard, but it was locked in the fully up position and the brakes would not engage. I then verified that nothing was blocking the brake pedal underneath it. At that point, around 3 to 4 seconds after the sudden acceleration began, I had entered the first turn of a 30 mph "S" turn at a high rate of speed, while acceleration continued at the vehicle's maximum acceleration rate beyond my control with the brakes not engaging. In order to avoid collision with a camper motor home and a small car following it, I went into the oncoming traffic lane at the second turn of the "S" turn. My truck fish tailed and struck a reflector marker on the left side of the road. To avoid going down a 50+ foot, nearly straight down drop on the left side of the road, I turned right. To avoid striking the motor home, I turned left, then right again to try to gain control. My truck rolled on its left side and landed upright on the right side of the road. It had been accelerating at its maximum acceleration rate with the brakes failing to engage and fish tailing the entire time. The problem appeared to be a catastrophic failure of the electronic throttle control and/or related electronic systems.

The contact owns a 2002 Toyota Tundra. The contact stated that while driving, the accelerator pedal became stuck to the floorboard and the vehicle speeded up out of control and crashed into a shed in his yard and crashed into a tree where it came to a stop. That collision loosened the accelerator pedal and vehicle was able to come to a stop. The dealer and manufacturer had not been contacted yet. The vehicle remains unrepaired in the parked contact's yard. The VIN was not available. The failure mileage was 180,000.

Cruising at 50 mph suddenly vehicle accelerator stops functioning and truck coasts slowly to side of road. Engine seems to be running normally, but no acceleration at all. In heavy traffic this could be very dangerous.

When attempting to put the truck in gear to leave a gas station the entire shifter mechanism broke off at the mount within the steering column. After 1 google search it shows this is very common with my Tundra truck (many postings and complaints-issues). I was in a pickle to move my vehicle and was not safe in doing so.

While accelerating from a turn, I heard a sound from the rear of the vehicle. Upon investigating the noise, I found the rear strap that secures the gas tank to the frame had rusted through. The gas tank was left hanging by only the front strap. What happens if a gas tank falls off a vehicle?

2002 Toyota Tundra. Consumer writes regarding problems with acceleration the consumer stated as he prepared to pull away from a side street onto a major roadway, he removed his foot from the brake and pressed the accelerator. The vehicle moved forward at what he considered idle speed, but did not respond to him pressing the accelerator. The consumer pressed the accelerator repeatedly, but the vehicle did not respond. He then observed the check engine light had illuminated. The consumer took the vehicle to his mechanic who informed him, the accelerator electronic relay switch was bad. The cost to replace the switch was $500. The consumer paid for the repairs. However, months later as the consumer prepared to exit a side street to make a left turn onto a major roadway, he experienced the same failure. The consumer returned to his mechanic and was informed the same relay switch was bad. The dealer would only warrant the part if the throttle body was replaced as well. The dealer stated a defective throttle body could cause the relay switch to burn out. The relay switch and throttle body were replaced at a cost of $ $1000.

Today I was cruising along at 50mph and my truck (2002 Toyota Tundra V8) felt as if the fuel cut out. I let off the throttle and got back into it and the response was very slow. Then there was no response at all as I coasted to a stop. The truck idled, but no response to the accelerator. This problem has occurred twice in the last week. Toyota troubleshooting code says it is a faulty accelerator pedal position sensor. They want $500 to fix.

I was driving in a large parking lot at a speed not more than a walk. I took my foot off the brake pedal and touched the accelerator pedal and the truck surged forward hard enough that the three people in the truck were thrown back against their seats. I immediately braked and the truck came to a stop without further incident. The acceleration was sudden and violent, and the only reason an accident did not occur was that there were no other vehicles or pedestrians in front of the truck when the incident occurred. The truck is a Toyota 2002 Tundra with the V-8 engine.

While driving 70 mph, the transmission stalled. The vehicle was towed. Dealership repaired the problem. The driver heard and felt a loud bump in the rear of the vehicle. The engine continued to run but the vehicle would not move when the consumer applied the gas pedal. There was rear end grease leaking from the right side rear showing on the wheel and tire. The mechanic stated that there was no connection between the rear brake, rear end leaking grease, the drive shaft and the failure of the transmission. The brakes were a major problem, the cruise control never kept speed or smooth, the left lower front ball joint had a catastrophic failure that caused the entire wheel, brake line and all essential components on the left side of the vehicle to come loose. The consumer requested reimbursement. The brakes were a problem on the vehicle, and the drums were replaced.
