At about 10 mph upon accelerating there is a growling noise and the ABS/traction control light comes on. This lasts for only a few seconds, but the car feels like it may not keep going.

The traction control and ABS keep coming on at random times. When you turn left or right it grinds and the car acts like it don't want to move. And the time that it grinds the traction control and ABS light comes on.

I have not had an incidence but very concerned about the malfunction that is going on with my vehicle at this time..I noticed a scrubbing/grumbling noise when I would turn the wheel either way left or right. After vehicle being put on machine for testing it was discovered that the upper strut mounts and bearing were worn and noisy on front struts......also my ABS and traction control light both came on at the same time and would not go off, the information system in vehicle recommended brakes be service.....the results from car being tested showed both front hubs have slack and both front wheel speed sensor harness are coming apart inside wire installation. The codes for ABS/traction control is...C0040 00.C0040.

My Impala's service traction control and engine power reduced lights came on 05/07/12 and I loss power to my car. I took my car in to a Chevy dealership to have it serviced, I was told after they diagnosed it that I needed a new throttle body so I had it replaced for the cost of $647 1 week later I was driving home and my car loss power and shutdown completely luckily I wasn't in heavy traffic and was able to pull over to the side of the road. I tried to restart it and white smoke came from the tailpipe so I had it towed back to the same dealership they told me after looking @ it that now I needed a new engine which would cost me $6200 I didn't get any lights on the dashboard or any other indication that I was having engine trouble and they cant tell me why it happened. I have my car serviced like clockwork @ the dealership spending good money for supposedly good quality service instead of some rinky dink garage but I guess that didn't matter. This happened just after warranty expired, I have 9100 miles and 3 car payments left.

Intermittent problems with "service traction control" and "engine power reduced". my Impala is starting to rumble and jostle when these warnings appear. However, I can't figure out the reason.

We purchased our 2007 Impala ss on 11/17/09 with 33,003 miles on it. On July 20, 2011 while driving home from work with my wife and stepson on the I-94 freeway in clinton township, mi., the leftside rear tire blewout. We notice that it had broke the inner plastic piece and bent the muffler tip and there was clearly no rubber left on the inside of the tire all you saw was wires. Had to put our spare tire on. Took the car into the tire shop on July 22, 2011 to have that tire replaced, service guy said there was no rubber left on the inside of the left tire in the rear, and the wires were clearly visible and showed us them, which we had noticed when this occurred. He also stated that on the rear rightside the wires were showing too. We had him replace all 4 tires on the vehicle. He also stated that we had been the 4th Impala they had replaced tires on in the past week. While on the lift we noticed that the back tires were slightly leaning out, like (/) left side and (\) right side, I told him that I want the tires back and he gave them to me. We took them home and took picks of them and the back of our car to show how the tires were still leaning out, and also took pictures of where the plastic had been broke in the wheel well. This has happened in less than 20,000 mile since we purchased the vehicle. I went to the dealership that we purchased the vehicle from and told the service guy what had happened, he stated that there was no recall as of yet on this problem but that other people had came in with the same complaints, that I should get ahold of GM and see what they say. He told me that he was aware of the police vehicle that had been recalled but as of yet knew nothing about all others. He stated that he wished he could do something for us but there was nothing he could do. When is GM gonna do something about this?

The 2007 Chevrolet Impala is an extremely unsafe automobile in wet or snow/ice conditions, even sand or salt; this car is the worst handling automobile possibly ever designed by GM. The Impala's rear end slides left or right with only a minimal amount of debris, water, or snow on the road. This is not just a little slip now and again, it is uncontrollable and an extreme safety hazard. Every person that has had any dealings with this type of car will tell you the same thing. Ask any mechanic, dealership, tire sales rep, and most of all, a 2007 Chevy Impala owner and all will attest to the poor design of this car. My wife and I will not, or should say cannot, drive this car when there is any sign of rain or snow in the forecast. Something must be done about this car. Not only is there a handling problem, but tire wear is almost unbelievable. The alignment specifications are at such extremes that tires are ruined in 10,000 miles or less. When looking at the car from the rear, the Impala's wheels tilt in to the point it looks as though they could collapse inward under the car. I have had the dealership and two different alignment shops check the alignment and all say the same; the car is within specs and to be extra careful as that the handling of these cars are unsafe. What gives" does it take a fatality to occur before GM will do anything about this design flaw? please look into this matter, lives depend on it. Anyone, and I mean anyone, who drives this car cannot deny there is something seriously wrong the 2007 Chevrolet Impala. A final note, it was brought to my attention that all police cars of this type were recalled for this very problem, is that indeed the case? if so, what about my family's safety and every other family that owns one of these cars? do we not deserve the same protection"

2007 Chevy Impala absolutely sucks on any amount of snow. Rear end fishtails left and right as if it has a mind of it's own. Absolutely ridiculous and unsafe!!

ABS & traction control service light kept coming on and I took it to dealership for service and they told me it was the hub assembly for the left side driver side that was covered under warranty and that I needed to replace my front rotors and brake pads (I wasn't having any problems with my brakes but because they said they needed replacing I went along with it). After repairs were completed and my vehicle "road-tested", I picked up my car and after leaving the dealership, both the ABS and traction service light came on again and I called and they scheduled me in for an appt. 2 days later. They couldn't find the problem so they called and told me that they needed to dig deeper and keep my car overnight and that I would now be charged a diagnostic fee to diagnose the problem up to $100. My service 2 days prior cost $224.90 so I was a little skeptical but I needed to know what the problem was so I agreed. I receive a phone call today stating that it is a wire in the harness that's causing the problem and it would be another $250 to fix. I check the internet to find out more information and not only has this happened to me but to several others and obviously this is a manufacturer defect and should be covered and how do I know that the dealership didn't cause the problem/defect by digging deeper to find out why the service lights were coming on and damaged the wire.
