Service stabilitrak warning, followed by reduced engine power, then car starts jerking.
I own a 2011 chevy Impala 4 door that has a very serious engine issue. I was on my way home and suddenly the service stability trac, and check engine light came on, then the message center displayed reduced engine power and low oil pressure then the engine shut off. I tried to restart the vehicle and it would not restart. I got it towed to a parking lot where it sat over night then it would restart but only for a few minutes. Once I got a scanner hooked up it had a p0642 code lost 5 volt reference circuit 1 and a cam sensor code I worked on this vehicle for two days and still have not found the issue. This vehicle needs a recall since this is a recurring issue with a few different model years of this vehicle and its always the same issue word for word, check engine light comes on, service stability trac, reduced engine power and low oil pressure lights come on the same p0642 lost 5 volt reference circuit 1. This is a very dangerous situation when going down the road and you lose engine power, steering and braking power. Gm needs to correct this issue too many people have had this same issue.
This problem has happened for many many years. Made appointments @ fuccillo chevy dealer, by then it’s gone off & they don’t know! well, just occurred again when getting new tires @dunn pulling in. 2011 Impala stabilitrak, engine power loss, then check engine light! thank goodness the mechanic printed me the codes & what they mean!! so- p2138 throttle/pedal pod sensor voltage correlation dtc p0523 engine oil pressure sensor/switch high input same complaint of loss of power as I’ve now seen others write about!! voltage referring to throttle ‘s ability to open/close properly.

It's like tires shifting make the vehicle slow moving an feel a grinding when feet on gas. . . Recently look an it says its 2 recalls chevy 2011 Impala.
Service stabilitrak warning light goes off and on intermittently when this happens the traction control light comes on when hooked up it shows no codes everything I’ve read on line is that it’s a electrical issue to replace wheel bearings or gas pedal or other list of sensors shouldn’t this be something that you should investigate to let owners know what to fix it seems to be a issue on several different models of chevy autos if forums are correct next step is it will go into limp mode or shut off completely that one would think would be a serious safety issue as you loose power steering as you have to fight to get to shoulder of the highway.
Today, 6-12-2022, driving on us highway 80 at 65 mph headed toward phenix city, al from columbus, GA, the the engine shuddered, then the "stabilitrack service light" came on, along with the check engine light, and a message for "reduced engine power. " then, the engine suddenly cut out as I was going uphill between the riverchase exit and the summerville exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under zero power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the summerville exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this model, the chevy Impala. I'm sure Chevrolet knows about this. . . The company should be forced to recall this car model and fix it before folks start getting killed due to total engine failure. . . Especially at a high speed like I was driving.
When driving the abs light illuminates, w/accompanying message: "service stabiltrak" followed by 'service traction control". Car grinds when turning left. Today the gas pedal felt like it was pushing back when pressed then it felt like it locked up for a second.
I was driving and a cop was behind me and he turned on his lights when I noticed his I tried to move into the right lane, and when I started to change lanes my driver wheel locked and it sounded as if I hit my brakes and the cop hit me my car spin out of control and I hit a tree.
There dashboard cracks really bad and apparently this has been an ongoing situation with chevy and gm vehicles. There's lots of static and I get shocked all the time which shutting my vehicle off or starting. I have had no off market work done to my vehile so its all as it was when original purchased.
When someone sits in the passenger seat the air bag light comes on. This has been going on in the both of the Impala's that we have had. This is the second one different year.
The rear defogger on my vehicle stopped working. Investigation lead to a video on the internet showing a melted connector on the passenger side fuse box. Following the steps in the video I found the exact same burned up connector under the carpet of my vehicle. Photos included. The connector was clearly not designed to handle the current the fuse was allowing to flow through. This is a fire risk as well as an inconvenience as now my rear defogger is inoperative. I never smelled the burning part but lost clearing ability about three weeks ago when driving in cold weather.
While driving on a city street, the door locks cycled several times, the radio went off and on, the engine seemed to stall as if a bad relay or faulty ground strap. Weather was clear and dry.
On 1/29/16 my car died and towed to dealer where I was told I need a transmission. The car only had 69000 6months ago dash board lights lit traction control, reduced engine power service stabilitrack abs. When I would step on the accelaretor pedal it would make a winding noise go to the floor and pop back up again. As I was driving down the highway all of a sudden I had no acceleration car had died. L pulled to the side of the road a few minutes later started up again this happened numerous times I told my son he couldn't drive the car because I felt it was unsafe. I called the gm they gave me a coupon to have the a diagnostic check on it. In sept I went to the dealer and he scanned my car for codes I was told I needed a right front hub part number 13582664, a right wheel speed sensor harness, 10340314, accelerator pedal, 84018392, and a vent valve 2085252. I can't believe a car dealers would let a person leave not informing the customer what a safety issue this is. I drove the car for a day because I couldn't afford to fix it and was trying to come up with the money again the car died on me as I went to accelerate now the car is sitting in my yard dead as a doornail. I called the dealer and explain the situation to the dealer at lannan Chevrolet in woburn and I spoke with the owner and the only response I got was what do you want there's a hundred thousand miles on the car I have been doing lots of research on this particular vehicle and I'm appalled between a 2008 and a 2011 there has been hundreds of complaints about the same issue. These are safety issues where people can get killed. Out of all these safety issues there's not one investigation that has been opened in regards to the issues. Nhtsa or gm needs to open an investigation immediately on these cars. There is a major safety issue and a recall is necessary. VIN number. .

Recall n140299, I have been having problems with no starts, stuck ignition keys, I received notice of recall, took vehicle to hessert chevy at 6301 e roosevelt blvd. Phila. Pa 19149, they played with the keys, said my car was done. Put key in ignition no start tried again it started. Dealer wanted 149. 00 to look further. Help.
Driving at about 70mph my check engine light came with with the reading service stability track, engine reduced power an disabled started, service throttle instantly I loss all rmps an my steering wheel almost fully locked while the car was still on motion. Luckily I was able to jus barley veer off the road into safety. Why would a car company have something like this in thier vehicles. That would lock the steering wheel while going at accelerated speeds.
Tl the contact owns a 2011 Chevrolet Impala. While making a turn, the vehicle completely lost power. Also, the stabilizer track and engine service indicators illuminated. The vehicle coasted as it regained some power, but the contact pulled over to the side of the road. The vehicle was able to slowly be driven to its destination. The dealer and the manufacturer were not contacted. The vehicle was not diagnosed or repaired. The failure mileage was 124,000.
Upon starting stabilitrak needs service. Redused engine power and check engine light all came on and car ran rough. Reatart and car runs but check engine light satys on.
This vehicle is under active recall. I have sold (traded-in,) the vehicle to a licensed car dealer. I informed the buyer verbally of the safety issue, but I wish to be certain gm is aware of the sale. Unfortunately, the gm website recall section has no way for me to register the sale, and therefore there may be a risk to the eventual buyer of the car, should the seller fail to mention to the buyer/end-user that there is an active recall. Gm is derelict in not having a way for recalled vehicle sellers to simply register the sale with the new owner's information. The gm recall site also does not accept any emails or any other online contact. Calling gm via telephone results in transfers, delays, and recordings.
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.
Wife and daughter were driving in car when all of a sudden warning lights came on and the vehicle lost all power in the middle of traffic. No brakes, brakes or steering,thanks god there was no accident.
Why is there not a recall on stability traction control? I see thousands of complaints on the internet for gm vehicles. It seems to me that gm just doesn't care enough after the sale. I just bought 2011 Impala and now the stabalitrack service light keeps coming on while going down the road. It will do this for no apparent reason but happens mostly when accelerating. Using the cruise control on level road and dash warning light comes on and throws car out of cruise, decelerating while gages flip around all over the place. Power loss and lack of acceleration are definitely safety issues. Pulling out of my driveway onto michigan highway and I get halfway across highway and car stops. This highway is 55 mpg and while I would have had plenty of time to cross the lane, car looses all power. Looking on the internet gives no help for a fix. I turned the stability traction control off, but the problem does not go away. I see on the internet that many people have taken there vehicle to the dealer garage only to get charged exorbitant prices for "possible" that do not seem to help. Gm should get this figured out and not let every dealer garage do their own guessing on what will fix this very dangerous problem that is not limited to single model or year but spans many years with many models. My first vehicle was a gm but this may be my last gm. I would like to give a date below but this has been happening since I bought the vehicle about a month ago and getting steadily worse. I have had it checked out but nobody can give me any useful answers.
Constant clicking from behind dashboard the blender something having to do with air/heat runs all the time even when car is not being used. It kills my battery life and since this is a malfunction from chevy I shouldn't be burdened with constantly replacing batteries. Its loud and lasts from 30 seconds to 3 minutes.
Service stability trac and reduced engine power lights came on. Car started jerking and making noises when starting car.
Wire supplying power to rear window defroster was found burnt at harness connector located on passenger side of vehicle near lower fuse panel.
Elay switch on driver side for air conditioner clicks for several minutes and blows hot air. The passenger side currently blows cold but now the clicking has been happening there also. This is obviously a common defect in Chevrolet Impalas that should be taken care of. This happens everywhere all the time moving and parked.
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.
While driving the traction control,stabilizer,engine power warning all come on and the check engine light comes on and sometimes the engine turns off. Pull off road, will not start then minutes later it starts. Check engine light stays on. After multiple starts the check engine light goes out . I have read multiple complaints about this ,yet the nothing is being done. To repair this problem. The effects of this is the same as the ignition turning off. Pending on traffic. This could be deadly. This has happened alot.
I begin noticing issues when taking off from a complete stop where the vehicle would lunge forward like it couldn't shift into first gear. I had that checked and nothing showed as an issue, so the mechanic said it had to be electrical. This weekend I am driving it and after 25 minutes in the car the check engine light comes on, as does the notice that my engine power has been reduced, and to service the stability traction control system. I was coming to a stop light when it came on and I pulled off to turn off the car and restart it as that would work when it failed before to reset the system. It didn't reset and I had to drive it with reduced power the rest of the way to my destination. I had this fixed a couple years ago. I did get a notice from gm about the issue and the ability to be reimbursed or getting it fixed if there was a current issue and I was able to get reimbursed for it. Now it is happening again, but my mileage is too high to get it fixed under this repair notice because the letter says that the mileage coverage is only up to 120,000. If this is a known issue and I have already dealt with it before, why should I have to pay for it to continually fail when it has nothing to do with normal wear and tear, which I would have no issue fixing as a part of maintaining the vehicle?! this should be something that gm would fix every time it goes out because it is clear the issue is a malfunction of the overall system and not linked to anything that the driver does or doesn't do to maintain the vehicle properly. In addition what if it has to be replaced multiple times as is the case with mine. I have always been a devoted gm customer, but honestly I am not sure I will ever buy another gm after this issue. It is unsafe and provides anxiety when driving, because it might fail at the worst time and could need fixed again even if I fix it this time.
Rear defroster not working. Discovered burned-up connector in a plug under passenger footwell fuse box. Internet research indicates this is a common problem affecting Impalas and other models over several years. This would therefore appear to be a design defect. Outcomes include reduced visibility due to inability to defrost/demist rear window and fire hazard due to overheated connector.
