This is an ongoing problem. Whenever I hit a pothole or a bump and I hit my brakes to slow down, the car makes this really loud grinding sound and the car does not stop at all and keeps accelerating. The only way I can get the brakes to engaged is by taking my foot off the brake completely and stepping on it again.

I have just filed a complaint and have since found my VIN number. I would like to provide that to you now as an addendum to my complaint. My car surged forward even while I was applying the brakes at the intersection of hwy 1604 and I-10 at 4:45 P.M on January 14, 2010. I crashed into the car in front of me smashing badly the front of my car but barely scratching the other car's rear bumper. The other party didn't want a police report. I have his name and phone number for verification of the incident. I will be in komaki, Japan until July 2010 so please contact me through E-mail until then.

My 2002 Toyota Camry failed to stop at an intersection in san antonio, Texas not far from my home. It surged forward and plowed into the car infront of me smashing the front of the Toyota but barely scratching the other car's rear bumper. This happened at 4:45 P.M on January 14, 2010 at the intersection of hwy 1604 and hwy 10. I know I was pressing the brakes when this happened. I will be in komaki, Japan until July 21, 2010. Since I'm not home now with my vehicle, I can't provide my VIN number until I return to the United States, but I will then.

2002 Camry le was parked in large mall parking lot. When started and put into drive, car began to accelerate as I pressed the accelerator pedal. As I applied the brake, the car continued rapidly accelerating by itself even though my foot was off the pedal. Brakes did not function at all; car continued to increase speed. I downshifted to neutral and car suddenly stopped with a jolt. I drove the car to local Toyota dealer where it was tested. Result:"could not duplicate concern. Vehicle operating as designed." This happened only once. Car now has 51,000 miles on it.

When I drive over rough road or a grate, my vehicle appears to not stop immediately. It seems to accelerate instead. It is very scary when there is a vehicle in front of you and you don't know whether your vehicle will stop. I drive very slow when I see rough road or a grate. I do not feel safe in this vehicle.

My 2002 Camry began "lurching" approx. 2 years ago. We have taken it for service 5 times, to no avail. We replaced spark plugs, a sensor and were told by one dealer that it was jumping from cylinder to cylinder, but they could not find the source of the problem. Two other visits to 2 separate dealers were unsuccessful in experiencing the problem during test drives. They even had a regional manager come and check it out. They said they have never seen this problem before and could not diagnose it. It happens inconsistently when cruising at lower speeds and again at higher speeds. Sometimes it is worse than others and then it goes days without happening. I am now concerned that it may be a safety issue connected to the gas pedal and would like to know what the problem is and have it corrected. I have also experienced issues when braking when going downhill on a bumpy surface. This has happened since I had the car. When I reported it to the dealer, they told me it was just the way the disc brakes work, but it was scary - feels like you don't have control over the car. We have been loyal Toyota owners for many years due to their history of quality, reliable cars, but have concerns now. Please let me know what can be done to help us with these issues. Thank you. Approx. Incident dates below are not accurate. It has been an ongoing problem for 2 or 3 years.

My 2002 Camry, purchased new, did not stop when I applied the brakes while riding over road bumps and engaging the antilock brakes. I had a dealer check for proper antilock brake function in 2002 and was told they could not find a problem. This condition is similar to that described for the Toyota prius.
