I own a 2009 Vibe. Recall has been completed re: Sudden acceleration. They removed drivers floor mat over a year ago. I had first episode today. Fortunately it was at about 10mph. When I engaged the brake the engine revved and the brake pulsated like the anti-lock feature had been activated. The engine revved for 3 to 4 seconds the car accelerated. When the engine revving stopped the brake engaged properly and the car stopped. Fortunately I was on a street where the speed limit was 25 mph and I had coasted down to about 10-15 mph approaching the stop sign. Had this been a high speed or emergency stop the results could have been deadly. Please contact me about this as this vehicle is not safe to drive. I will also be contacting the NHTSA. The above is a copy of information I sent to General Motors via their Pontiac web site.

When coming to a stop, occasionally the vehicle will lunge forward. I have noticed this on many, many occasions since purchasing the car in July 11. When coming to a fast stop (such as when someone pulls out in front of you or someone suddenly stops in front of you -- ABS is not being used as these are not panic stops) the brakes will work as they should until the car is almost stopped and then the car will lunge forward and I suddenly need to apply more force to the brakes to make the car stop. I suspect that the computer in the car is using engine braking to assist in slowing down the car and when the car hits a certain speed (or some other variable) the engine braking is turned off which causes the amount of pressure that I need to apply to the brakes to suddenly increase which gives the impression that the car is lunging forward. Regardless of what is causing this issue to occur, it is a safety issue. I have grown used to this issue and now can compensate for it, but it is still distressing when it occurs. I have talked to other Vibe/matrix owners and they all state that they have the same issue. I believe that this is a significant safety issue as it could easily lead to an accident.

Driver reported failure of vehicle stability control and anti-lock brakes. Warning lights were flashing on the dashboard. Vehicle was taken to repair shop and repaired at cost of almost $800 to replace the rear wheel assembly where the ABS sensor is located.

I was able to detect this before any accident occurred. While checking the rear brakes I noticed that there is uneven wear of rear brake pads. Passenger side outer pad is positioned in an angle which causes premature wear of that pad while all other pads are wearing evenly. Such defect (caliper position) causes rotor damage and possible wheel lock. This is a second Vibe with the same problem that I've seen. The passenger side rear caliper needs to be adjusted and repositioned.

2009 Vibe had recalls done to my car yet it still accelerated up over 2000 RPM and 70 km without touching gas pedal also the traction control and ABS lights came on at same time. In my opinion it has nothing to do with gas pedal or floor mats..the dealer came and picked it up as it wouldn't stop doing it. They changed cam sensor it didn't work.then they told me they were putting in new comp. System. Its will be a month this wed. And car is still at dealers.
