chevrolet avalanche Problems

chevrolet avalanche 2011 Complaints

POWER TRAIN

when i am slowing down to a stop the transmission will suddenly make the vehicle surge forward quickly. if i not just as quick to apply a firm brake i risk hitting the car or pedestrians near me which has happen on several occasion. on one occasion, as i was turning into a parking space the vehicle suddenly surged forward so forcefully that it cause the front left bumble to travel outside the planned path and hit a brick column. this problem only occurs in situations when i am slowing down, i.e. making turns, traffic lights, parking, etc. it can be frightening when it occurs unexpectedly. recently took into local chevrolet dealer. they acknowledged the problem and said chevrolet engineers are working on a fix where the transmission's computer is altered. but they didn't seem confident in the outcome.

POWER TRAIN

at times when my avalanche is slowing down (close to a stop) the truck will lunge forward. it feels like it's something with the transmission (downshifting?). almost like a surge of energy unexpectedly pushes the truck forward. it does catch me off guard at times, but luckily i have not struck anything when it has happened. it does not do it all the time, but rather intermittently. i am hoping that gm can figure out why this is happening and possibly issue a recall to fix the problem.

VEHICLE SPEED CONTROL

i have began to notice when slowing down (foot off the gas and coasting with foot on brake, or brake applied) at any area where my speed decreases to less than 15 mph that my avalanche will seem to sort of lunge forward. the first time i experienced this i believed it was related to me and ignored it. the next couple of times i experienced this i thought there may be something wrong with the gas or engine. i have spoken with several other owners (who own the same year model avalanche and suburban - the suburban and avalanche are made from the same frame/body/parts) and they state experiencing the same issue. i must be cautious to ride my brakes and be read to heavily apply them now when taking an off/on ramp and vehicles are in front of me as my vehicle has lunged forward before with vehicles in front of me. i noticed here that (at the time of this submission) that two other users have reported the same incident. i am hoping that my report here will help open an investigation with chevrolet on this issue.

ENGINE

i own a 2011 chevrolet avalanche ltz and at times when the truck down shifts it will lunge forward. i really need to have my foot firmly pressed on the brake to keep the truck from possibly hitting something or someone in front of me. it does not do it all the time and it's rather random. i feel that is worse then it happening all the time because i don't know when to expect it. i have not received any notification of a recall, but i feel a fix is definitely in order. something is not right and it could result in a crash.
