As I was driving on the straight highway at about 70 MPH I let off the accelerator due to a car ahead of me driving under speed limit as I put pressure on the pedal it sped up but felt a slight hesitation, I thought not much of it until I see a 18 wheeler coming up fast , I put a little more pressure on accelerator to by pass the slow car in the right lane as I did this I felt my gas pedal wobble to the side w 18 wheeler still behind me I tried to speed up and make it to safety because I knew something wasn't right , just as I get back in the right lane I felt the pedal give as if it just broke off ... I kept driving to catch the next exit and to get off of the two lanes and get myself to safety but it wasn't catching speed I panticked pushed my energy lights on and kept pushing the pedal for it to go still not much help .. So I just held down the pedal ,( by this time it's almost on the floor board swinging left to right I finally get a break when an exit came up I took the exit prayed to god and looked at the pedal , to my shock it was hanging on by a few wires ...plz see to it that this gets checked that was the most scariest situation that has ever happened to me while driving thank god he was with me, I usually never complain but this I just couldn't pass up it is scary and could of been fatal .

Anytime I go to accelerate after coming to a complete stop at a stop sign, red light, or etc the car hesitates and then jerks forward. The car hesitates and loses power. While driving down a busy city road the car turned off. I had to try and steer the vehicle to the side of the road. The steering wheel would barely turn.

When coming to a stop my ABS service stability traction control service brake lights all come on then my 2011 hesitation to stop when braking. Even if I go slow or just stopping at a stop sign. It pushes my foot from the brake. A cranking noise sound. I have gotten brake, tire rods, roaders and new tires. I don't know what else to do. This happens specifically when on the highway when having to come to a sudden stop. I almost crashed several times not being able to stop. Mind you my car only has 65000 miles on it. This is just too soon.

I hear a horrible grind when making a left hand turn after a stop, car also felt like it did not want to go forward causing hesitation in left hand turn - very dangerous with oncoming traffic. Have had it to mechanic many times, either they couldnt find the problem or would fix this or that and then problems right back within days if not hours. Occasionally get service stabilitrac and/or ABS lights, usually lights would clear by next day when I took to mechanic and again they'd either find no problem or try a fix -still a problem. I believe they're going to try to replace wheel bearing next but from all forums I've read this doesn't seem to help people either, problem comes right back, recently rack and pinion had to be replaced costing $700 to fix, within 2 days I heard the grind, had hesitation on a left hand turn, noticed fluid under my vehicle upon return home, hoped it was A/C condensation, within days the power steering is going out again - turns out new rack and pinion is leaking and car is completely out if power steering fluid again after 2 weeks. I can't help but wonder if the sound and grind isn't what's causing my rack and pinion issues as well? Have owned 2 years now with this problem continuously throughout ownership of the vehicle. Approx. 68k miles on it when purchased now almost 90k have to be very cautious making left hand turns that there is no oncoming traffic as hesitation may cause you to get hit if vehicle can't turn in time. Have to completely let off gas and try again sometimes still grinds if so repeat is all you can do. Becoming very scary and costly with no fix found so far!!! Please investigate! Multiple posts regarding same issue some on newer models, very much a safety issue I can't even teach my child to drive in the car as I am afraid for their safety in it, as well as my own safety ever time I try to make a left hand turn.

We own both a 2011 and a 2013 chevy impala. Both vehicles grind and hesitate. They both act this way while taking off from a light, backing out of the driveway and then putting it in drive and any other time it feels necessary to do so. Except while being checked by the mechanic. We owned a 2007 impala that did the same thing. Our remedy, push the traction control button to the "off" position. Stopped making the noise and no longer hesitates after putting it in drive. Of course, we have to do this each and every time we get in the car. No more buying chevy's for us.

2/17/2015 was the second event. I was driving approx- 65 MPH up a mountain when my electronic display panel showed stabilitrack/service traction control/vehicle in reduced power. As the power suddenly reduced I lost power steering control and brake function. Since I was traveling at a up hill grade, I was barely able to jerk the steering wheel enough to roll across the lane of traffic beside me to the side of the road. I wasn't able to get out of the road completely and was almost hit by a logging truck. After removing the keys from the ignition for a few minutes, I restarted the car without any hesitation. The engine light still remains on at this time. I did contact onstar and have them run a diagnostic test which revealed a problem with supposed fuel system. I have not taken it to a dealership yet. After so many complaints on various sites that I have reviewed, looks like gm would do a recall and investigate the problem before someone loses their life.

While driving along a curvy river road my check engine light , my traction control and the stabilize light came out. Then the engine reduced power. Barely made it home. Waited for a few minutes restated the car and it ran normal but still feel the car hesitate. Every time I drive it I worry that its coning to do it again. I live in the part of the county that gets snow and am worried its going to happen during a storm, this needs to be addressed.
