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.

Car cut off at speed in curve after quick dash warning: stabletrack.....reduced engine power..... Then cut off. No power brakes, no power steering, engine stopped running. If traffic had been in opposite lane would have been head on collision. This needs to be a recall. My wife will not drive her impala any longer. This is my 14th chevrolet - possibly my last!!!!!

I was driving home from work and I was doing 55 MPH,and the car started to hesitate,and the dashboard info read stabilitrac, engine safty mod, and reduced power. Then the car started to slow down,and when I tried to give it some gas the engine started to knock,and the temperature gauge went all the way up to the top. I pulled over and shut the car off,and opened the hood, and it wasn't even over heating. After letting it sit for a few minutes I started it up and went about five hundred feet and it did it again.

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.

My chevy impala when in motion has signals for service stabilitrac, the check engine comes on and the a message that says reduced engine power shows up. It seems like alot of impala owners are experiencing this and something should be done! The stabilitack goes off and the check engine ligts stays on but usually goes off, and then a few days later it will happen again.

#1 every time I move the drivers seat my airbag light comes on saying that the airbag is disabled. #2 the car's traction will act like I'm on ice (even on a hot 90 degree july day). The traction light comes on and the engine will gear down, to the degree of loss of engine power, power steering, and power braking. This has happened several times while driving long distances on the highways I found recalls pending for these problems and my VIN # is not on the list. Well I'm telling you now this is very dangerous and very scary. Someone is going to get injured or killed!!

Service stabilitrak indicator showed up and the vehicle does not run properly (engine seemed to want to stall, loss of power, rough idleing, transmission 'kicking'. This problem should be repaired by the dealership and not the consumer since the costs of repair are (can be) extremely high. Manufacturer should ensure the parts they use for stability and safety will last for the life of the vehicle.
