Vehicle performed poorly over 35 mph on highway with the rear of the vehicle swaying excessively during snowy or wet conditions. The tires on the back of the vehicle wore prematurely on the inside. I purchased four sets of new back tires in a span of 4 months and had to have two alignments done at separate times because the first didn't initially fix the problem. It came to a point that I was frightened to drive my vehicle during snowy or wet conditions in fear of causing a major accident. I have spent roughly $700 on this issue and believe it could have been resolved if GM would have addressed the consumer's vehicle problem initially.

Steering knuckle in 2007 Impala...strange noise when turning wheel all the way to the right.

- Wayland, MI, USA

I purchised this car in April of '08 and it has been failing since I bought it. There is a vibration while riding in the car that makes your body bounce. The dealer states they don't feel it, but I have cronic back pain from it. I have had it at the dealer several times and no fix. I took it to an alinement shop they told me that the stuts were set out from the factory so the tires don't hit the grond flat like they should. The problem causes my tires to slip out of balance constantly making the vibration worse. My windshield and dash both make craking noises now from all the vibration in the car. It makes for a very uncomfortable ride. I am on my 3rd set of tires at 28.300. The brakes don't work properly, the dealer has turned the rotors twice for warping. Now they are grooved and they tell me that "it's normal" and I don't have the normal stoping power I should. The power stering squiels, but they can't hear it. The front end has a banging noise when going over bumps, "they don't hear",but I can feel it in the floor board when it happens. The car is sluggish when excelerating, "no problem found". the fuel econemy has decreased as well. While on an incline the car roles backward like a standard, "it's normal" I have never had a car do that without the trany being bad. When stoped at a light the trany takes a couple of seconds to reengage for take off. Tps repeated problems not working poperly. The cars handling is very poor in the rain, snow, or ice. The muffler system has a leak as well.

Dear NHTSA, please investigate the following serious concerns that have affected my vehicle safety in addition to other Chevy Impala drivers: Vehicle: 2007 Chevy Impala. 65,000 miles, 1 owner, Impala ls 3.5 L V6 safety concern # 1- intermediate steering shaft - GM refuses to acknowledge the seriousness of this problem. My vehicle's steering wheel clicks during driving & temporarily jams causing a feeling of disconnection from the road. It has caused a momentary loss of steering control, and I feel this is a serious safety concern to be addressed. This is an ongoing design problem for many GM models(as per my google search), GM refuses to make corrections to the design nor issue a recall. --------------------------------- safety concern # 2- power steering pump- power steering pump loosing effectiveness & turning performance, meaning pump may be failing at any time. This too is another common problem with Chevy models. Please encourage GM to expand power steering pump recall to include Chevy Impala models. ---------------------------- safety concern # 3- rear back seat center seat belt looses tension when used in conjunction with infant car seat. When vehicle goes around 30 mile/hr turns or mild turns, seat belt locking mechanism(the one that holds the seat belt tense during braking) disengages & permits the seat belt to loosen causing child seat to move across the seat & or in one serious case with my son flip sideways(luckily my wife caught the seat as it tipped sideways). I have followed all safety instructions as per car seat manufacturer (evenflow aura travel system). This is a concern, since the tension only stays firm in abrupt stops, this leads me to question the safety in a roll over scenario. I have since used the seat level car seat hooks since the past few events( this greatly reduces the ease of sharing the car seat between vehicles). My other vehicle(Nissan Altima) has no such problem, the tension mechanism on the Altima remains firm

When pulling out of a parking lot, I felt a "clunk" and my car became very hard to steer. I contacted GM and they stated that there was no recall on my vehicle, but I could contact the dealer and he might be able to repair my vehicle. The vehicle had just passed the warranty mileage by 400 miles. I did contact the dealer's service manager and he stated that the steering column had broken at the weld. He repaired the vehicle at no charge..

My car is a 2007 Chevrolet Impala,4dr, white. I bought it new from a dealer in pickens SC, who went out of business soon after I bought it. I had no trouble with it until the incidence described herein. On January 10, 2010, I was going down rutherford road in greenville SC to the laurel baye healthcare home in greenville SC. I turned into the road to laurel baye from rutherford road. This is a sharp right turn into a road that goes uphill. Halfway through the turn my car's steering wheel locked completely. I could not turn my wheels at all. The car was running fine, and all other systems in the car worked, but my steering wheel could not be moved. I put on my brakes, which worked, and drove to the other side of the narrow road. I turned off the motor, and waited a few seconds. Then I turned my car back on. The wheels were still locked. At that time another car drove up, and the driver got out and tried to get my car wheels to move, with no success. In turn, a policeman, and my neighbor tried to make the car wheel turn, but no success. In the meantime my neighbor got the car to release the wheels, and I drove it home, and it appeared to be ok again. The next day I took the car to a Chevrolet, Buick, Cadillac dealer in greer SC. I reported what had happened, and they said they would examine the car. The service man said they could find nothing wrong with the car. The next day I called and threatened to write letters of complaint. So they took the car again, and kept it for 11 days testing it, and still reported they could find nothing that had caused the wheels to lock. In the meantime I searched the internet and found many reports of GM cars with this same problem. There have been class action suits, and suits which have been settled by GM. Now I feel my car is unsafe to drive, and I feel uneasy driving it. I would like to report this incident and hope that GM will be forced into a recall of all affected vehicles.

I hit a 6 inch curb at approximately 30 mph. When the car hit the curb the steering knuckle broke causing the left front tire assembly to come off the car rendering me in no control of the vehicle. I personally feel this broke too easy and should have been able to withstand the impact of a 6 inch curb. If the knuckle would not have broke I would have been able to stay in control of the car and not have caused as much damage that did occur from the tire coming off the vehicle. This situation could put people's lives in danger as such a small impact causes the wheel to come off taking control away from the driver.
