My car's engine power was severely reduced suddenly when I was driving on interstate highway 275 north in tampa, FL. A message showed on the dash: " reduced engine power, service traction control" and the check engine light was on. This happened today around 7 pm on oct 30, 2016. My car is a chevy Impala 2009. I searched online and found thousands of messages about the same error message of reduced engine power on many models of gm cars including Impala, malibu, trailblazer, silverado. This worries me very much as so many same error messages and engine problems happened on so many gm cars. My research shows that gm has done nothing to resolve this problem yet. So this irresponsibility of gm on this specific issue put the lives of hundreds of thousands of drivers in danger. I hope NHTSA looks into this problem and pressure gm to issue a recall if possible to take care of this serious problem. Thank you!.

The check engine light comes on and it says service stabilitrak reduced power engine. Then the car slows, it may jerk, or stall. This has been an ongoing issue. I've taken it to be looked at least 2 or 3 times. I've been told they don't see anything and I should bring the car in to get serviced the light comes on. It usually last a few days but it will come back on. I've also received a letter from Chevrolet about fixing it but when I took it to get serviced I was told that it had to be under a certain amount of miles. This is a safety hazard and could cause a potential car accident or even death if traveling at high speeds and then all of a sudden your car engine reduces power. I know this because I've almost been in an accident twice due to this issue.

Major safety issue! while driving on the expressway hours from home reduced engine power/service traction control/check engine lights came on. Cruise control disabled as well. Car stopped on the expressway, steering wheel locked up. Luckily we were able to coast to the side otherwise this could have been a disaster! vehicle was towed to a nearby service station where it is currently located. There are several complaints out there like this. Gm needs to recall and fix this problem!.

Car is currently at 134k miles and just gave me a "reduced power engine", "check traction control", and a check engine light. I googled around and came across a lot of chevy Impalas around the same year (07-10) are having the same problem. It seems to be something with the "accelerator pedal positioner pedal sensor. Also reading into it, it claims that this problem can cause the car to suddenly stop from 60mph all the way down to 20 or zero. This is extremely dangerous and needs to be looked into before someone is hurt or killed.

Got a message on my dash a few months ago about "service traction control" while driving. Traction control light lit up also. Parked car and turned car off then on. . . Message gone. Took it into service. . . Showed no error codes. Today (5/2/16), it did it again with the traction control light and the check engine light simultaneously lighting up. "service stabilitrak", service traction control", and "engine power is recuded" are the messages I got today along with the check engine light and the traction control light being on. I had just gotten off the highway so I wasn't going fast when this happened. I was close to work so I parked it at work. Turned the car off then on again and the messages were gone and traction control light was off but check engine light stayed on. Turned car on again at lunch 1. 5 hours later and the check engine light is off now so I doubt anyone will be able to diagnose or fix anything today. Taking it to service to see if it threw any error codes a little later today. I've researched this issue and found that this has happened to a lot of people while on the highway. If it happens to me and I'm in an accident because of this, I will sue the s**t out of gm. I have two small children and if any of us gets hurt or killed, there will be h**l to pay. This issue should absolutely be recalled. It is not due to my key/ignition issue. Already handled that recall. Losing power in the middle of the highway randomly is absolutely dangerous and I'm now very afraid to drive this vehicle. Will never buy another Impala again.

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.

Service traction control and check engine lights came on this morning. Then a message saying my engine power is reducing. I just bought this car 3 weeks ago. I called gm customer service and they told me there was nothing they could do, even though there was a recall regarding this because it was over the 120000 mile warranty (but I just bought this car 3 weeks ago!!!).

When your at a complete stop vehicle gives a hard jerk like someone has rear ended you. All of the Impala's have a failed transmission pressure control solenoid which can cause accidents when it jerks very hard causing someone to run into the back of another vehicle. No check engine light or anything will come on letting you know the problem. Years 2000 to 2015 all have the same problem. Needs to be recalled before someone seriously gets injured.

Takata recall. The contact owns a 2009 Chevrolet Impala. The contact had not experienced a failure with the vehicle until it was repaired per NHTSA campaign number: 14v355000 (electrical system).

In addition, the key fob failed to lock and unlock at different points in time. The contact notified the dealer and they were unable to provide a solution for the various electrical failures. In addition, the brakes were slow to respond and the dealer replaced the rotors, which did not prevent the failure. The contact was informed that the brake actuator needed to be replaced. The repairs for the brake system did not prevent the failure. The contact later received notification of NHTSA campaign number: 16v507000 (air bags, electrical system). The parts were not available.

I was driving on the highway and all of the sudden check engine light and traction control light come on. Warnings service traction control and reduced engine power are displayed and all but shuts my car off in the middle of the highway causing cars to slam on their brakes and swerve barely missing me. I get over to the side of the road and turn the car off. Then turn the car back on same messages and won't go no where. Do the same thing again only waiting longer and no messages but check engine light still on. I drive home. Next day no warnings or lights. Couple weeks go by does the whole warnings and lights and slows car down again but doesn't completely shut it down. I was in regular street traffic this time about 35mph. And now it's more frequent sometimes a couple times a day to once every day or two. This needs to be looked at. I'm reading about this problem on a lot of Impalas causing major problems and wrecks.

Driving on interstate vehicle suddenly lost all power and would not accelerate & quickly decelerated with any prior warning. 18 wheeler almost rear ended me. Instrument panel displayed “engine power reduced”, “service traction control,” “service stabilitrak”, and “check engine light. ” finally exited interstate safely and shut down engine thinking it was going to blow up and after 2-3 tries to restart messages disappeared and vehicle seemed to be ok. Took vehicle to mechanic & found codes evidencing the loss of communication between the tac and or the app units causing vehicle to go into limp mode but could not get the condition to reoccur. Mechanic had to remove codes to permit to duplicate problem, could not duplicate and told me to wait until reoccurred. While looking for repair shop was scared it would happen again received letter from gm stating if the above condition had occurred they would fix. Called gm dealer mentioned letter they refused to repair unless the messages were present on panel, refused to look at the vehicle. Called gm customer service referencing letter, explained gm dealer refused to repair. Was told by angela issue was safety related problem but gm would not admit to safety issue. Gm agreed to pay for one hour of diagnostic time to determine if vehicle qualified for repair, dealer was unable to duplicate problem, refused to repair. Called gm and was told no repair would be made even though the problem had occurred as stated in the letter and to wait until situation occured again then not to start engine and tow to gm dealer. Was told gm would not pay for tow or inconvenience and if they could see codes they might repair problem. This is definitely a safety issue since when this occurs the vehicle loses all power and basically shuts down and will not accelerate beyond 5 mph if at all. Leo nelson 937-554-9778 noslenlsn@gmail.

I own a 2009 Chevrolet Impala. I was driving on the highway at 65 mph when the check engine light, traction control light and engine power reduced light came on. A few minutes later, in heavy traffic it said engine shutting down and there was a short countdown displayed before the engine died completely. This is very dangerous and I am lucky to have been able to get over to the shoulder without getting hit.
