This has happened on numerous occasions. While driving my vehicle will turn off. Sometimes me vehicle will have trouble starting. Turning the key will not engage the starter, there will be no attempt of the motor to turn over. This continues to happen even after the removal of all key rings from the ignition key. Today (11/18/14), my Impala died while driving and the engine light turned on. The code stated that there was a faulty ignition switch.
Driving on highway when check engine light came on followed by alternating "service stabilitrak" "service traction control" "reduced engine power" messages. Additionally, while driving the transmission began to shift hard from first to second. By the time I got home and parked in the garage (approximately 3 miles from start of incident), the vehicle was making a loud clanging noise. Vehicle delivered to kool Chevrolet in grand rapids Michigan on 11/4/14. They have had the vehicle since. The only thing they have found is that the computer indicates the codes went off while the car was parked. Otherwise, they cannot duplicate problem. I am worried about driving the vehicle and this incident happening again. I do a lot of highway driving and the sudden reduction in speed is a hazard and could lead to an accident.

I was driving down the street and suddenly I heard a popping sound and I noticed the car wasn't accelerating normally so I made it to my destination and I started the car up went to put it in drive and it wouldn't accelerate is was though the car was in neutral so I put it in reverse and it went into reverse put it 3rd gear wouldn't accelerate the I tried 2cd gear and it drove kind of ruff so I then tried 1st gear and and I was able to make it home at 15 mph so I took the car to the Chevy dealer I bought it from and to my surprise they say there were some defective parts in the transmission and they could rebuild the transmission for 2100 dollars and I would have to pay 850 to have it fixed because my car is out of warranty as 7/23/14 the car has the airbag service light and tire sensor light that appears on the dashboard.
Loss of power, service stabilitrac, service traction control started flashing...the car lost all power, shifted extremely hard and would only go about 5 to 10 miles per hour. I was on a main road with a lot of traffic when this happened, extremely dangerous situation. I took the vehicle to the GM dealer the first day, they could not find the code and the car ran fine on my way home from work. The next morning it did it again, took it back to the dealer and they had to replace the throttle body which costs almost $700. That was in February, I am now 400 miles from home and it is doing the exact same thing again....going to call a dealer today and hopefully it will be taken care of at no cost. I called GM about this issue and their response was that there is no recall on this VIN# at this time, yet I know there are recalls out due to the throttle body.
1) airbag light intermittently has gone on and off for months. I asked dealer about it, they said it would be expensive to diagnose because they would have to trace the wiring harness, removing seat and dashboard. Labor would be expensive. I complained to GM on a couple of occasions and was given a case#. I was told car is out of warranty, therefore, it would be my expense to have this diagnosed and fixed. Dealer said airbag would not deploy if light is illuminated. This a major safety defect. Fall 2013. 2) the rear window defroster stopped working last fall 2013. I had to pay for total repair as it was not covered under warranty. They said it was a wiring issue. Impala's have been known to have issue. Oct 2013. 3) the gas pedal fell off while I was driving. Dealer said they never experienced anything like that before, but would have to replace the entire assembly. Not covered under warranty, therefore, entire cost was mine. Safety issue. Sept 2013 4) the evap vent valve and solenoid had to be replaced. System leak pressurized evap would not hold. Apr 2012 other issues have been reported/repaired, however, do not have paperwork at time of this complaint.

While driving, reduce power in engine. Check stability trac, and lost acceleration. The car shut off in the middle of the freeway. Restared after a 10 minute wait. Check engine light was on, but now off. Happen from time to time.
I own a 2010 Chevrolet Impala. I have had my housing gear replaced and other suspension items in the last year. Since my last major job (housing gear), the car has been making a click when turning the wheel and when going up hill. When the car is going uphill and shifting gears it make a click/pop sound. I have taken my car to the Chevy dealer and they constantly act as though they can not hear the sound, which makes it so easy for them to not repair. I have taken my car in for this over 5 times and leave with the problem still being. On two of those occasions they found other issues which resulted in the warranty paying for the problems. My warranty includes a $100 deductible. So I have paid a deductible to get one problem fixed and it has not been repaired to date. I am truly frustartaed, as I am not a mechanic and need my car fixed. I drive a toddler around daily. I feel insecure with my cars driveability. My car needs to be fixed.
Trying to pull into heavy traffic the transmission slipped and had to let off accelerator to get transmission to shift. This left me half way out into traffic for just a second.
While driving on the highway and accelerating to merge, the car felt as if it dropped a gear or two and the power was noticeably reduced. The service light on the dash came on and the error message "service stabilitytrac- service traction control" came across the dash. Now the car when it accelerates "jerks" as if it's having trouble making it to the next gear when moving between 20-30mph on the speedometer. The power in accelerating after 30mph is dramatically reduced the faster you wish to go.
[xxx] I have attached this link as a reference so that you can see that I am not the only one going through this. I have been experiencing the same problems as alot of these people as far as the car jerking and with the car reducing its speed (service stabilitrak warning). I have been to the dealer 3 times already, which I had to replace transmission lines and an accelerator sensor (which they replaced the whole accelerator). Please note my complaint is no reflection to the service dept at that dealer for they were extremely courteous and as helpful as they could possibly be. I was very happy with the dealer, but I am not at all happy with the way GM is not handling this. As you read through the comments on that link, this is a very dangerous problem and it needs to be recalled asap. I travel on major expressways 4 days a week with my mom and don't want to end up in a bad accident because of this. I have photos of the dashboard messages if needed. As of today, they are not on but the car is jerking again. Please consider action on this. -- thank you.

Driving home Friday night 12/26/12 on cruise set at 65, bang, car dropped power drastically, kicked off cruise, and the three rotating messages appeared on dash, 1)service stabilitrak, 2)service traction control, & 3)engine power reduced. Both orange placards lit up on dash, service engine and traction. Pulled out of traffic and re started the car. Was able to drive at normal speeds but codes still rotating and placards still lit. Couldn't get it into the shop until Monday 12/31/12. When I started it up to take it in, codes were all cleared and car ran just fine. Dealership told me it was the pedal sensor and would cost me $275 to repair. How can we get GM to do a recall on this on going issue? this is a 2010 Chevy Impala lt with 45000 on it. This repair should be covered under warranty and I was told it is not. There have been numerous individuals with this same sensor failing at about 45000 miles. A sudden drop in power to a speed of 25 while driving at highway speeds is very dangerous. It is amazing with as many failures as have been reported to GM on just the edmunds car form site alone that there have not been any serious crashes. Please take a good look at this issue and see if you can't get GM to recall these sensors and get them replaced with better ones.
I was driving to work, nearly at the end of a 50 mile trip, the car was functioning normally with no abnormal noises or indications of problems. I drove the car into the parking lot and was making a slight right turn, traveling at about 15 mph, when suddenly the car screeched to an immediate halt and stalled the engine. The sudden stop was violent and threw me against my seatbelt. I moved the gear selector lever from drive to park and restarted the engine without any trouble. The engine ran smooth and without any unusual noise. I put the car into drive, but it would not move and it made loud grinding and clunking sounds. I put the car in reverse, but still it would not move and again made loud noises. I put the car in neutral and a friend came over to help me push the car to a more safe area, but still the car would not move. Apparently the drivetrain was locked up and would not move, no matter what gear position the transmission was in. The car was later dragged on to a flatbed truck and taken to my local auto service center, where they determined the transmission was bad. The vehicle was then towed to my local Chevrolet dealer to be fixed under the GM 100,000mi/5 year powertrain warranty. I am very shaken up by this incident and fear what would have happen if the vehicles front wheels would have violently locked up like this at highway speeds. I fear the result would have been a total loss of control of the vehicle and possibly severe injury or even death to myself and others. I hope GM and the NHTSA investigate this incident and find the cause of the transmission failure with the goal of preventing this from happening again before someone gets hurt or killed.
