When slowing down the vehicle surges forward even when brake is being applied. It does not appear to be related to engine surge as it does with sudden gear change as if the vehicle is speeding up from a stand still. This occurred as I was turning into a parking space which caused the vehicle to veer uncontrollably to the right (was making a left hand turn into parking space) and hit a brick column. It has also happened when coming to a stop and persons were about to walk across road scaring them and me!
2002 chevy avalanche - problems with ABS brakes, truck won't stop as described in NHTSA action # pe05020, called the local dealer where I purchased new in 2002. I was told the recall is VIN # specific, however the NHTSA action describes the recall as state specific( I reside in aurora, ohio-southeastern snow belt of lake erie). The vehicle had brake work done 2 yrs after purchase and the service and repair form stated " rear brakes corroded causing premature failure ".
Tl* the contact owns a 2011 chevrolet avalanche 1500. The contact stated when he applied the e brake, the vehicle suddenly accelerated without warning. The contact mentioned that he was able to maintain control of the vehicle by shifting into neutral and shutting off the ignition. The vehicle was taken to a local mechanic who was unable to diagnose the failure. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and current mileage was 5,500.
I was in line at a drive through at burger king and as I pulled up to the cashiers window to pay for my food the engine started to accelerate. I put my foot on the brakes as hard as I could while the truck was shaking and lurching trying to go forward. I can't say for sure how high the tachometer was, but it seemed to almost peg for a few seconds while this was going on. Finally I jammed the transmission into neutral and the engine returned to normal idle.
Service stabilitrac system indication comes on, with check engine light, and engine power reduced. Happens randomly, cannot find a "common cause" spent lots of money on PCM, bcm, memory seat module, battery cables, battery, brake light switch, etc. Etc. Dangerous condition when vehicle drops into power reduction mode.
