I was stopped at a stop sign on a dry road,when I pressed the accelerator the car felt like the engine was going to shut off and it would barely move. A few seconds later the traction control light and ABS lights came on. After the traction control and ABS lights came on the car went fine.this is not the first time that this has happened. Also sometimes when you step on the brake pedal it feels like there is no pressure on the pedal. When this happens the traction control and ABS lights come on again. This has happened several times in the past 2 years and I have taken my car to several different auto mechanics. I have replaced both front wheel hub assemblies at least 4 times in 2 years. Each auto mechanic will tell you a different diagnosis when I take it to the shop. I have contacted gm about this problem about 10 to 12 months ago and they say they are not aware of any problems with this model of car. I don't know what else to do to resolve these problems with my car. It is starting to happen more often now, and my wife will not even ride in my car anymore because she is scared to. I would really like to see an investigation started into this matter. If you go to some chat rooms on the web you will find many many people having the same problems with their impalas. Thank you for reading this complaint.

The catalytic converter caused the car engine to turn off in the middle of the road. The car was having acceleration problems getting to just 25-30 MPH and while driving it, the engine turned off and took several attempts to restart it. After a couple months, I found online that letters (special policy number 05551) were supposedly sent out to impala owners for an extended warranty for this faulty part. I'm the second owner of this car so I wasn't aware of this and just got it replaced in october. A chevy district specialist said the car was bought 18 days before this warranty coverage and I was 2 years outside of it because I'm the second owner. The car is in great condition and less than 84,000 miles on it as of today. I'm not sure what warrants a recall, but several sites have customers saying they've had to replace this part multiple times on their cars because gm sold a car with a faulty design.

My ABS and service traction control light stays on. When I turn my steering wheel, there's a funny noise and a feeling like my brakes are scrubbing.

When using my cruise control, turning it on and canceling, there is a clunk. Brought it to the dealer under warranty and said based on another chevy impala it was normal.
