Vsc, trac off, ABS and brake lights came on while driving. High pitched buzzer/alarm started and remained constant. Brakes became very hard to depress and I lost most braking power.

My 2002 Toyota 4runner has a faulty throttle position sensor (part # 89452-35030) that causes loss of power while driving (at all speeds). This loss of power is very dangerous as the car will be driving along at a stable speed and then suddenly just start slowing down even though my foot stays on the gas pedal. This loss of speed puts me at serious risk to be rear-ended by a car behind me or potentially get hit from the side as I am crossing an intersection. My mechanics and I have diagnosed the tps as the issue. This is a very common problem (there are multiple forums on the web about this). Here are some of them below: www.yotatech.com/F2/throttle-body-sensor-89452-35030-A-239929/ www.ttora.com/forum/showthread.php"T=16753 www.ttora.com/forum/showthread.php"T=13283 www.Toyota-4runner.org/3rd-gen-T4rs/118506-throttle-position-sensor.html please get Toyota to issue a recall for this part. It is something that needs to get dealt with before there are more serious incidents. Thanks.

I have already filed a safety complaint regarding my sudden acceleration accident approximately 4 years ago. I noticed that Toyota has issued a recall for this problem for Toyota 4runners going back to 2003. My vehicle is a 2002. Basically, I'm writing to urge NHTSA to asktoyota what is different about the gas pedal assembly from 2003 to 2002 because there is no doubt there was a major malfunction with my car and if the assemble & parts manufactures is the same from 03 to 02 then the recall should be extended. Also, the other main reason I'm writing you is so that there is a record of me requesting my vehicle be included in the recall so that way if something happens to me again we will have a record of it.

I own a 2002 Toyota 4runner with approximately 94,000 miles. The vehicle primary use is driving less than 10 miles a day off highway. The following alarm lights came on: Brake light, check engine light, vsc light, trac light, ABS light, and the speedometer quit working. The vehicle was taken to mike calvert Toyota in houston, tx to diagnose the problem. Their scanner was unable to identify a code for the problem. The conclusion was that the ads control module (skid control sensor) was at fault and thus had to be replaced. The assistant service manager, grant miles advised me not to drive the vehicle until the ads control module was replaced. The cost for the parts and labor was quoted as $2377.01. It would take 3 to 5 business days for the part to be ordered and replaced. I had to rent a car from the dealership because of the vehicle was deemed unsafe to drive and because of the lengthy repair time. The cost of the rental car is approximately $289. Because of the possible safety issues with the ads control module (skid control sensor-part # 8954035270), I am registering this notification with the NHTSA.

I own a Toyota 4 runner. While driving across country last fall I noticed that the truck would accelerate rapidly when I had cruise control on. The cruise control would kick in as it should have but it would accelerate very rapidly and felt out of control. Once it began the acceleration, it would never stop and level out to the appropriate speed as it should have. It would continue to accelerate. Braking worked in slowing the vehicle down, but it frightened me while I was driving. I do not use the cruise control now as a result of this. I was driving R/T from ca to denver, co and it happened several times during this trip.
