The contact owns a 2010 Chevrolet Impala. The contact stated that while driving at various speeds, the front-end of the vehicle would lower and the front end was unstable. In addition, the check engine warning light would remain illuminated. The vehicle was also consuming an excessive amount of engine oil. The engine fan had failed and the transmission was faulty. No further information was available. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 120,000.

The car can have moments of power loss where the speedometer suddenly, erratically spikes while the tachometer slightly lags. It almost stalled my vehicle while transmission was in drive while stopped. It feels like dragging when the power loss occurs. This has occurred randomly for the past month, mostly during interstate driving with cruise control operating. It has happened the last six times I have driven, but the previous several times it did not occur. It also occurred in a similar random fashion for the prior two weeks. When it does occur it feels like power drain and deceleration that can last a second and this will occur several times during a twenty minute drive at 70mph. Mechanics at two shops seem confused and don't know where to begin except for a transmission fluid flush. That was completed and the problem has persisted. There are no related error codes. To lose power suddenly and unexpectedly could cause an accident especially if a system failure shuts off the vehicle while driving. This vehicle has had an oil consumption/burning problem since I bought it with around 60,000miles. It needed 2 quarts of oil added between the last oil changes. I have spent $1400 in July of this year on gasket replacements and that did not stop the leak. More gasket heads and an oil pan are going to be need to replaced and the estimate is another $1400. This is too much to be spending on possibly related issues in a short time span that may not resolve the problem.

Sometimes when driving an "engine reduced" warning will pop up and when it does so, the car limits the amount of power applied when accelerating. I have to turn it off and sit a few minutes before it goes back to normal.

- Indianapolis, IN, USA

The diagnostic revealed that there are 11 codes in the vehicle system. These codes ranged from passkey system failures to evap codes to transmission. Suspected failure of wiring harness altogether with possible BCM/cam failure as well. During battery test there was a regular drop in voltage while connected to the scanner reflecting a drain in the electrical system that could further be causing an issue. Codes are P0513, P0523, P0700, P2122, P0411, P0449, P0455. When driving stabilitrack, engine power reduced, and stabilitrack traction control. Sometimes the car shuts off while driving and the steering wheel will lock, I'd w ok old have to pull over on the side of the highway or street and pop the hood just to get the car started again.

My car has worked fine scince I bought it with no check engine codes.I pulled into parking space and put car in park, all of a sudden it stalled out and will not crank anymore but has power.key will not come out of ignition and battery will not shut off.the ignition switch is a very common problem with Impala and is very dangerous.it locks people out of there cars, gets stuck in gears, wont let key release, wont start, sets off anti theft signal which cuts power to door locks, trunk, starter, fuelpump, and more.I have read hundreds of forums of this problem with Chevy Impala that has been going on for years without the problem being fixed.elderly women breaking down on highway or car just shutting off and not restarting.it is soooooo common with Chevy that they can diagnose the problem just over the phone.this is very unacceptable and has to be dealt with.please recall this problem.

Driving uphill & the service stabiltrak & the serice traction control words came on followed by reduce of engine power & the service engine light & traction control light came on. We could still drive at about 20 mph uphill & 45-50 on flat roads. We shut the car off 4 about 2 hrs 2 cool down. But then as soon as we headed up a hill it started all over.

I was sitting in the parking lot with my engine running for about 10 mind. All a sudden 'reduced engine power' came across my dash and my service engine light came on. I turned my car off. About an hour later I turned it back on and the message was gone. Then as I was driving down the road my service air bag light came on. It only comes on when the passenger seat beat is clicked on. And my driver side back door auto lock stopped working.

2010 Chevy Impala only has 58,000 miles on it. I've already had been having issues with the car not starting all of the time and now after putting new tires on it, I am driving down the road and get "service stabilitrack, " "service traction control, " and "engine power reduced." I was on a major highway going about 60 mph and was almost rear-ended due to the sudden loss of speed. I was able to move into a turning lane and get to a parking lot without getting myself killed. I still, however, have to figure out how I'm getting home from work! I had noticed when I first went out that it seemed to be shifting hard, but the roads were wet, so I thought perhaps it was the stabilitrack kicking in, not going out! I have two small children, who thankfully were not with me. The car has been nothing but trouble since I've purchased it. With such low-mileage, I figured I was good to go for awhile. I have a 2003 Chevy Tahoe with almost 200,000 miles and have not had this many issues out of it!! contacted Chevrolet, but am told no recalls have been made. Why not"!"!

2nd air injection check & shut off valve has failed for the 3rd time on this vehicle. I contacted a friend of mine at GM and a global technical specialist in the exhaust manifolds/heat shields/sai division of the General Motors global propulsion systems stated that there was a corrosion durability concern with this part that resulted in elevated warranty. There is now a improved service pn available that replaces the pn that have been used in my vehicle. I feel that GM should recall these bad parts and refund us for them. Each time this part needs to be replaced the cost is over $400 to me. My first replacement part went on 1-30-13 at 46737 miles. The 2nd replacement part went on 7-8-14 at 71368 miles. Now the 3rd replacement part needs to go on at 115429 miles. The 1st replacement part cost me $567 to replace at the dealership. The 2nd replacement part cost me $478 to replace at an independent shop. It will cost me the same or a little more to get this replaced for the 3rd time. Is there anything that you can do to help me?

I have a 2010 Chevy Impala lt with 90K+ miles on it. I originally bought the car in 2011 used with 40K+ miles on it, so the car is no longer covered through warranty. Engine power reduced, service stabilitrac, etc. I'm a full time college student, and a full time uber driver. Last night I was with a passenger on [xxx] towards O'hare airport. My car reduced speed and suddenly dropped speed from 70mph down to 50mph. As I turned on the emergency light and start steering to the right to get onto the shoulder I was in the third lane to the right (the expressway is 4 lanes) as I was turning to the right to get onto the shoulder and to get to safety my steering locks, and there was a reckless driver going 100mph trying to cut off traffic. The lanes to the left were blocked so he had to cut me off by overtaking me by going onto the shoulder. He damaged his right rearview mirror and probably scrapped the right side of his car pulling off that reckless stunt. Had I delayed the breaking for a second I wouldn't be alive making this post today. Luckily I turned the car off, waited for a few minutes, turned the car back on and took the nearby [xxx], and waited with my passenger at the nearby target parking lot for the next uber driver to pick up my passenger and get her safely to the airport. Had I not acted quickly, my uber passenger would have missed her flight.
