While driving at any speed the car shuts off. It completely loses power. No power steering or brakes. I was going 60 on a highway and it stalled thank god it wasn't rush hour and there weren't many cars around me. This happens at 10mph 30, 40, 50. No matter how fast or slow you are going the car shuts off and leaves you with no brakes or power steering. This is a huge safety issue and should be a recall. It has been diagnosed as a faulty ignition switch. I have had it looked at by 3 different mechanics and they all say that is what it is. Now I have to pay to get a new ignition put in. I have had the car 18 months and new problems occur constantly with it. Chevy should be paying for a new ignition switch to be installed.

Loss of power steering at startup, becomes intermittent after driving for a few minutes, then service stabilitrack notification comes on sometimes while driving. The stabilitrack notification will come on while making a turn, doesn't matter if it is a right or left turn.

Traveling a state highway at the legal speed of 70 MPH, had to break very hard. As the car slowed down the engine shut off and power steering failed.

I was driving on a highway going approximately 55 MPH, the engine light, stability control light, and reduced engine power light came on at the same time. Within two (2) minutes of the dash warning lights coming on, the car completely shut it self off while I was driving in the left lane going 55 MPH. I lost steering, had no power, or braking. I threw the car in neutral, in an attempt to get it started it while I was in motion with no power. The impala didn't even try to turn over. The car wasn't responding because the power steering / braking was not responding. The impala went into "limp mode" without warning. I let the car cost for a while until I could find a safe spot to apply the emergency brake. I really had to muscle the steering wheel with some significant force to get it to turn. I have never had any problems with this vehicle before this issue. It turns out that the "pedalassembly" gas pedal sensor went bad, causing the 2011 impala to go into "limp mode" while I was driving.

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 going to work approx. 6 months ago a deer crossed the road in front of me. I attempted to steer away from the deer only to notice that the steering wheel felt as if it had no power steering. I was lucky that the deer changed its course or I would of ran into it head on due to the steering being so hard. The 2012 impala has the same issue? Gm is not addressing this issue. I have a pi document from gm which is not available to the general public. It confirms this steering issue with the 2011 chevy impala (all models). This pi states to the mechanics to take consumers for a ride in a parking lot and perform parking lot maneuvers at slow speeds.then tell the consumer it is a normal condition if the steering issue is duplicated. My attorney still has possession of my independent technical expert report which states that the steering is extremely hard at low speeds. My case was lost in arbitration and the decision was made in a few hours. I do have the document no. [xxx]. Document id [xxx]. I want all consumers to know what to expect if they purchase a 2011 impala and have this problem. I did note that the federal safety agency has this steering issue documented. However gm states that this is not their bulletin and none exist for this issue. I was given this pi by mistake. *js information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

While driving on thruway my 2011 chevy impala lost power steering went due to a belt broke within the engine compartment. Nearly lost control of car. After getting off the thruway,we noticed that a pulley had come apart. Which caused the belt to disintegrate.
