2011 Chevrolet Impala engine complaints
Page 4 of 6: complaints 71 to 100 of 134, newest first, as owners wrote them.
I turned my car on to let it warm up after work, then started driving home. Then some lights popped on. It said service stabilititrak. It said that it was reducing engine power. Service control soon. It was very scary driving home. The car would take off by itself and it felt like it was stalling out. Its a fairly newer car 2011, I shouldn't be having these issues.
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.

Driving 2011 chevy impala in city traffic. Service stabilitrak, service traction control, reduced engine power warning messages received. This has happened several times at intermittent intervals in the two years I have owned the vehicle. In some instances, the engine shuts off and all power steering and power braking is lost making it very difficult to control the vehicle. After research, this is a problem that gm needs to address. I have found that if I pull over when the warning messages display, shut the car off, wait approx 10 min, the car will start again, the messages will be gone, and the car will drive normally. The check engine light remains on and then goes off within a day or two.

My family and I were traveling from newark, nj from the july 4th holiday back home to raleigh nc on 95 south in virginia and going at a speed of 72mph approx. And the car/engine just turned off at that rate of speed with 2 children in the back seat of the vehicle. After we sat on the side of the road for about 45min the vehicle proceeded to start and we made it home to nc. The following business day after the holiday I took it to my mechanic giao auto located on capital blvd in raleigh nc and he could not determine why the vehicle shut off the way it did. So I continued to drive just with precaution. I received a letter on 8/21/2014 regarding the recall and was livid because this has happened to my family while driving on the interstate! I believe that this may happen to my family again and do not want to risk this, so I would like to know what can be done to ensure that my children have a safe vehicle.

Coming off of a freeway, the exit is a wide curve. About half way through the turn (going toward the right) the engine turned off. Lost all power steering and brakes. Fortunately, I am strong enough to be able to muscle the car through the rest of the curve and pull over to safety. The muscling caused minor injury to left shoulder. Car did restart without a problem.
The car keeps running after it is turned off. The fan also keeps running, then the next morning the car wouldn't start. The air won't turn down and sometimes it doesn't work at all. There doesn't seem to be a difference between air and defrost. While I am driving, the light keep getting dim, then brighter, then dim, then bright. It was the next morning then when it wouldn't start! Sometimes when we put the key in, we couldn't get it out. We had to keep trying to turn it on and off, then it finally let us take the key out.
Throttle control shut down,engine power reduced,car shut down on highway without warning.
While I was driving the service stability pack and traction control light came on and immediately after the reduced engine power came on. The car then jerked, and shut off while I was still driving, and wouldn't start again until approximately 30 minutes later. There were no wet nor road hazard conditions that would have caused this to happen. Furthermore, I was driving at 60mph when this occurred in moderate traffic and almost got rear ended. This is a very unsafe issue, and I was told that the gas pedal needs to be replaced. Since then my vehicle has done this several times. This issues needs to be recalled because a lot of individuals have complained about having the same issues with the impala. What is it going to take an injury or fatality for a recall on these vehicles. Moreover, any vehicle that shuts off while driving at any speed because of an issues with throttle body/gas pedal needs to be recalled because this is a major safety issue.
Pulled into 35 mile per hour traffic and lost engine power. Warning lights and message for stabiltrac, service traction control and reduced engine power came on. Experienced reduced engine power with traffic approaching from behind. This happened with 22,000 miles in 7/2013. The engine control module and stabilizer shaft link were replaced. This happened again 2/2014 with 26,000 miles. The throttle body cover and sensor kit were replaced. Just today, 7/23/2014, it happened again with 30,000 miles. Each time it has happened pulling into 35 mile per hour traffic and experienced reduced power.
The A/C motor behind the glove box is making a clicking noise and I have noticed on a lot of gm and chevy vehicles the same defect. I think this should definitely be a recall considering a lot of people I know have the same problem.
I was driving down I-74 outside peoria il and the stabilitrac power reduced popped up on the dash and 3 seconds later it stated the anti-theft engaged and shut my car off. I almost got rear ended by multiple cars on the interstate. I was in the left lane and barely made it to the side of the road. I emailed gm and they have not gotten back to me yet. I emailed them the same day it happened.
The service stabilitrak, traction control, and reduced engine power warnings came on and the car started to lose power going around a curve. I temporarily lost the ability to accelerate nearly causing me to get rear ended by a vehicle behind me. Since the incident occurred the car has been very sluggish and unsafe to operate. I am planning to get this serviced asap. After reading many forum posts online regarding this safety issue, I believe a recall should be issued. I was shocked to see how rampant of a problem this and that it is usually caused by a faulty throttle body that isn't covered in the 100k mile powertrain warranty. Myself and many others from what I have read believe this to be a very dangerous malfunction. If this were to happen at high speeds on the highway someone could very easily be killed if their car loses power due to this.
First incident was on (05-29-2014check engine light, service traction system, and reduced power lights came on. Car took off with a jerk. Had car scanned for codes. Came back as the throttle position sensor. Had that changed today(06-06-2014) and code cleared out. Was doing great unill this evening while I was driving home tonight ,(06-06-2014),on highway doing 56 m.p.h. And car shut off. Check engine light came on, service traction control system, and reduced engine power. I quickly veered off into median and turned flashers on. There were several cars behind me. Car would not start right away. After several minutes it started with only check engine light on. My children and I could have been seriously injured or killed had I not been able to react as quickly as I did. Obviously I am not the only one experiencing this same issues based on the investigations on here. I have also researched on many gm forum posts with many reporting the same issues. Gm basically apologizes in the forums and tells them to take it up with the dealership.

2011 chevrolet impala. Consumer writes in regards to vehicle engine problems. *smd the consumer stated on several occasions, the vehicle stalled without no warning. When the engine power reduced, a light appeared and the consumer was unable to accelerate. The consumer stated he waited several minutes, before trying to re-start the vehicle. The vehicle was taken to the dealer, for an inspection, but they were unable to duplicate the problem. However. A couple of weeks later, the engine service light and engine power reduced light illuminated again.
I was driving and suddenly the car lurched and the check engine light came on as well as messages that said, "reduced engine power, check stabilitrak and service traction control". I made it home and parked the car in the driveway for a day and a half and when I started it again, the messages were gone but the engine light was still on. I brought it to my local dealer and when they checked it, it came up stored code p2122- accelerator pedal sensor. I have had this car 6 months and it only has 42426 miles on it and now I've had to spend over $300 on a repair. It is ridiculous that this sensor failed already. After doing some research, I found that this is a common problem with many people experiencing the same thing. Gm should be forced to fix this issue and reimburse all of us who have had to pay to fix their mistake. They are obviously using inferior parts and their consumers are paying the price. It's no wonder the american car market needed a bailout when their parts don't last 40,000 miles.
