Car gets service stabitrack, traction control and ABS warning on dash. Replacing wheel hubs with sensors does not fix this issue. Sometimes the car will want to apply brakes while driving or reduce engine speed. I have been through many forums with people reporting the same issue on the same car and through multiple years of manufacturing. From the research I have done in the last few days it looks like hundreds of owners have reported this issue but chevrolet is not doing anything to correct it. Not sure at this point if it is the wiring harness causing the problem or if this could be something with the computer that controls the stabitrack, ABS and traction control. If cars are loosing power and or the brakes are being applied with out driver control this can lead to dangerous driving conditions for the car owner passengers and everyone else driving on the same road. With how many people are reporting this I do not see why the car owner should need to pay thousands of dollars to diagnose and maybe fix the issue. From what I have read some people have had to pay for multiple service events and the issue still not resolved.
2011 Chevrolet Impala brakes complaints
Page 2 of 2: complaints 11 to 39 of 39, newest first, as owners wrote them.
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.
When taking left turns the car makes a loud grind noise then the stability controll will turn on. Now the check engine light and stability controll light popped on while driving while also having engine power reduced which then applied my brakes causing me to almost go off the road.
I continue to have problems with my front left hub after replacing. I have replaced the wiring harness as well. Wondered if there are service bulletins with this same issue. While driving the car it makes a horrible grinding noise described to me as the hub adjusting the speed of one tire to match the other. It also flashes brake assist and stabilitrack issues as well as anti lock alert. This happens mostly turning left but most recently even while driving straight down the road.
My service stabilitrack, reduce engine power light came on while I was exiting the freeway. When this happened I had almost no brake pedal. I couldn't stop at the light at the end of the exit, luckily no other cars were around. If I had been on a main street at 45mpr and had to stop for a red light I would have never stopped on time. I'm very lucky no cars were at the light waiting or coming in a different direction with the green light. I see this problem all over edmunds and on you tube and as far as I can tell it's 100% chevrolet. How can this not be a recall. There are dozens and dozens of the same complaint on edmunds and you tube. It seems like every you tube video has a different fix for the problem....from pulling out the fuse to the stabilitrack to over a thousand dollars in repairs. Does there have to be a death to get the attention of chevrolet. The light had come on a few times before but this was the first time it happened while I was driving. Usually it came on and I would turn the car off for a few minutes and it would be fine......so how could this be anything but a malfunction if it goes off and on at any whim. They must know about this problem as it seems to be very prevalent and again from what I have read it's always a chevrolet.
Front brake calipers binding on my 2011 chevy impala lt. New rotors and ceramic pads installed 2,000 miles ago and now warped again. I have $275.00 invested and was told by my mechanic that there may be a factory recall on the calipers. There is 56,000 on my 2011 impala now. The vehicle was in motion while this was happening and got worse after a few hard stops. Also check stability control system warning came on and vehicle went into reduced power mode which is very dangerous in traffic.
Bought car 4 days ago. Now the warning light and message keeps coming on about service brake system assist and traction control system needs service. The car bogs. It does this while driving and when at start. The tcs iimblim stays on at all times. Shouldn't this be a recall or under warrenty?????
Tl* the contact owns a 2011 chevrolet impala. While the vehicle was parked on an incline with the contact's foot on the brake pedal, the vehicle was started and proceeded to shift from park to drive. The vehicle started to roll backwards and struck the vehicle in its rear. There were no injuries and a police report was filed. The manufacturer was notified of the failure. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 77,595.
Today our 2011 impala displayed msgs for "service traction control, service stabilitrack, engine power reduced". We started to pull over as it dramatically slowed. The engine then died. We were on a 6 lane highway going 45. This could have been deadly. We received a recall letter for the throttle position sensor. The dealer did not repair it because they could not reproduce the error.
While driving down the highway, my car shut down. This was very dangerous. I pulled over on the shoulder and every light was on stating engine power reducing. I have had this same part replaced twice in 1.5 years and there is something serious wrong with the impala.
G.m. Replaced my ingintion switch on a national recall. I was hit in left rear qtr. Panel. I lost all power and could not stop or steer the car. I careened across highway and ran into a house. No air bags deployed either. G.m. Sent a team to recover computer info and has now told me there is no problem.
The vehicle is always shaking when braking the vehicle makes weird sounds when turning the vehicle jerks all the time or something when trying to step on the gas the vehicle won't go
I was driving down the highway going 70mph when my service engine light came on and a message stating the stablitrak is on and the engine is reducing speed! Acceleration pedal wouldn't do its job
Tl*the contact owns a 2011 chevrolet impala. The contact stated that while approaching a stop sign, the brake pedal was depressed but the vehicle failed to stop. As a result the contact crashed into a curb and an embankment. The air bags failed to deploy. The contact sustained shoulder and right hip injuries but did not require medical attention. The front passenger sustained ankle injuries that required medical attention. A police report was filed. The vehicle was not diagnosed or repaired and the contact was unsure if the vehicle was destroyed. The manufacturer was not notified of the failure. The VIN was included in the federal safety agency campaign number: 14v355000 (electrical system). The failure mileage was unknown. Updated 7/23/15*cn updated 11/9/2015
My wife was driving home from work going 65 down a very busy highway. All of a sudden the reduced engine power light, check engine, stability control off, and traction control lights came on. The car begin to loose speed. Luckily she was able to get over to the right shoulder without anyone hitting her. When she got to the shoulder the car was running really rough. She turned it off waited a few minutes and restarted it. It then ran fine but the check engine light remained on. She made it home and was scared to drive it again. I took it to work last night and made it about halfway to work and it did the exact same thing except I was able to get it to maintain 45mph. When I came to a traffic light though the engine was running so rough the car was very hard to stop. I made it to work. When I came out to go home the first stop light I came to it started acting up again. From the light I was barely able to get it to go 25mph. I pulled over and shut the car off waited a few minutes and restarted. Everything was fine again. I made it about 5 miles and all the lights came on again but I was able to maintain 45mph in the 55mph zone I was in. I took it to my repair shop and they said it needs a throttle body. They also said gm has had allot of issues with these. I called my gm dealer to see if it would be covered under 5 year 100k mile warranty and they said that it isn't. If there hasn't been an accident caused by one of these throttle body issues yet I would be surprised. It's very dangerous in heavy traffic and all of a sudden you can't go.
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.
Reduced engine signal came on shortly after service traction, brakes, steering, came on then car shut off no power to anything. Brakes, steering nothing worked. Put car in neutral to try a restart nothing. Got car to a complete stop took the key out. The dash made a weird noise almost like something reset. I put keys back in turned the key car started no problem only thing the check engine light was on. Took vehicle home went back later that night. Started it up and check engine light was off. This happens almost once aweek. 2nd issue heater blower going down the road just shut off weather -2 plus a wind chill. Had it serviced they replaced a module blower ran fine for 4 days, weather advisory windchill temp is -10 45 miles away from home heater blower not working again.
Traction control light came on and immediately afterward the stabilitrac light came, engine power was reduced and I was barely able to get vehicle home as the engine had no power, barely enough to get the vehicle to move forward.this is a very dangerous condition and could cause someone to panic and crash may occur. My wife and I own a collision appraisal business and have processed approx 60,000+ claims for various national insurance companies. I also believe that this same condition has possibly been the cause of some of those claims as I think back about insured complaining about brake issues, loss of eng power and now I see that same condition and issue on my own vehicle. I really believe that this should be investigated and fully checked into as this is a very dangerous problem.
My service traction control system light keeps coming across the dash board. It seems to reset itself, but there has been a time when turning....my dashboard lights came on and didn't reset for about a week. If this isn't a problem, then what is it?

Tl* the contact owns a 2011 chevrolet impala. The contact stated that the ABS sensor and traction control sensor illuminated each time the contact made a turn or applied the brake pedal. The failure was getting progressively worse. The contact stated that the vehicle made a loud noise upon pressing the brake pedal and when making a turn. The vehicle was taken to an authorized dealer. The technician indicated that further diagnostic testing was required to determine the failure. The vehicle was taken to an independent mechanic who diagnosed that there was a loss of the signal from the ignition to the ABS system causing the brakes to lock. The contact was referred to an authorized dealer to have the repairs performed. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 42,000.
Dec 2013 vehicle hit pot hole while braking at approaching intersection, after that warning lights started flashing ABS brakes/tract control/stab control, I was unable to brake, then shut down. Since then temp gauge went bad n was replaced. The 3 above dash warning lights continued intermittently, worse when it rained. At take offs n turns car would jar n ABS brake system would pulsate(grabs). Hub/speed sensor was replaced, this did not help. Accessory outlets, when contained w a charger, doesn't maintain contact w power source (such as disconnection/loose connection), causing power surge resulting in 2 iphones to have bad aux ports. May 2014 blower motor started intermittently not working for seconds, then minutes until today sept 6th, 2014 when something under-dash (near blower motor) overheated filling car with smoke, then car shut down while moving once again, car smells awful from the burning! Car has been a lemon and not covered under power train! Seems like auxiliary elect fuse box(passenger rt foot board), and harness is shot as well as whichever harness is sending power to speed sensor, among many other things I could not mention (problems/defects) due to so many other issues w this 2011 impala which is now worth 7000 as trade at chevy, I paid 13500 on oct14, 2014! I've checked several ground connects n they seem okay.
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.
I was driving 25 MPH when a dodge ram 5500 made an impromtu stop and my car an impala 2011 didn't stop therefore I crashed behind the dodge ram 5500. The impala was totally destroyed and the dodge didn't have any damage at all.
Tl - the contact owns a 2011 chevrolet impala. The contact stated that the ESC, service traction, and engine power reduce warning messages illuminated. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure. The vehicle was not repaired. The VIN was not available. The failure and current mileage was 52,000. Klmj
The malfunction indicator (page 5-17 in my manual) came on and the message was to prevent serious damages, go to your service station immediately. I was in the parking lot of a grocery store, and made my way to the interstate heading to our service station when my car stopped dead in the middle of interstate 485 about 3 miles away maybe ( about 7 miles from home and our service station). I was in the far left lane of a major hwy that was/is under construction when I felt something unusual. I grabbed the steering wheel as hard as I could between the cars and just made it to the far right side of this major highway. The steering, A/C and brakes were gone and then I realized if I did nothing I would have been run over by the trucks on this interstate. I got close to the guardrail and collected my wits and called both aaa and the charlotte nc police. Fortunately I did not have the opportunity to see if the air bags would have gone off! The nc police were to come immediately but never showed up, but an hour later the aaa driver came and assisted to help me out of my car into his tow truck. He said to sit in the AC and drink some water. It was a hot day in the carolinas. No AC, nothing to drink and could not open my windows. I could not open my door as cars whizzed by me on the driver's side. The car just died. Finally got it towed to the chevy service station and the repairs cost (enclosed) $696.84. After seeing the event on tv I realized I could have been killed!!!! Please do something about his issue, as I hear all the horror stories of the innocent killed upsets me. I was fortunately to be able to get me and my car off the highway while cars whizzed by on a busy highway but how many haven't.
We purchased the impala in april of 2013 with 35,408 miles on the clock, we drove it around town then we took it on a trip to california from las vegas a few months later, when we where on the way to california on a not so steep downgrade we hit the brakes at about 70mph to slow down the steering wheel shook violently side to side like the famous 'death wobble' but we only slowed to about 60mph. On the way back it did it again this time went from 70 to 67 MPH, we took it to the dealer and they said my rotors needed to be turned and gave me the dealer cold shoulder.. I replaced the front rotors and all 4 new tires as of today and it still doing it, went back to the dealer and same thing, this car is unsafe to drive over 50mph but the dealer does not care and is out of warranty... I will never buy a gm product ever as long as I live. I took video of the shaking from 70 to 67mph I will post it on youtube. This car is certified too not that it mean anything to anyone.
Tl* the contact owns a 2011 chevrolet impala. The contact stated that the brake pedal was too narrow and when depressed, the contact's foot would slip off the brake pedal. The vehicle was not taken to the dealer and the manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was 190 and the current mileage was 6, 8000.
Driving downhill a truck pulling a trailer brake suddenly in front of me causing me to have to brake hard. The brake pedal shuddered and felt like I needed to take my foot off the brake but I couldn't! Additionally the steering wheel shuddered horribly side to side. Braking on the remainder of the hill and for a while after had the same chattering, shaking, shuddering, and sort of brake grinding feeling making me feel like I could not rely on the brakes and maybe the steering was having problems too. Scared me and felt terribly unsafe!!!! This happened once before about a year ago with this car in a similar downhill sudden braking situation. I drive to avoid having to brake suddenly but sometimes it is unavoidable and I don't want to drive this car anymore because it feels too unsafe.
