I have a 07 Chevy Impala ss. I replaced the tires Sept 28, 2009, had them rotated at a GM dealer in Jan 10 when I got an oil change. My husband was doing some brake work 2 weeks ago and noticed my tires were completely bald on the inside edges. After researching the issue, my car has a manufacturers defect (tsb # 08032) and GM engineers created a camber fix kit for the issue but GM will only pay for repairs if the car is coded as a "police vehicle". I was on hold for over an hour in an hour an a half conversation with Chevy customer service this week. They told me they would document it but basically sorry for your luck. I asked for a manager and after a 3 minute conversation she hung up on me saying she would note my case as "dissatisfied" but there was nothing else they would do. She said all I could do was contact NHTSA and place a complaint. I don't believe GM is standing behind their product as their new tv ad eludes when they know there is a problem, fix it for their fleet customers, but refuse to help the average citizen. From reviewing the complaint site many others have had the same issue with their Impala. GM won't help the average citizen fix this manufacturers defect unless a recall is issued; these were the words of the customer care rep I spoke with. Please review all the complaints on this issue, request GM provide their company stats on the fleet vehicles they've fixed, and issue a recall for this issue. This should have been covered as my car is under full warranty at this time but they look at this issue as an alignment issue not a rear suspension issue (which is what it is) to get themselves out of paying for their mistakes.

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.

There is a rear suspension alignment issue on this vehicle. The rear wheels are kicked-out causing inner wear on the tires after minimal mileage. I was forced to replace all four tires (because they had been rotated) after only 25K miles.

- Tucson, AZ, USA

I am having excessive wear on the inside of both rear tires. I have replaced my rear tires twice in less than 5 months. Both of my rear tires blew out at the same time on 2/24/10 while I was driving on the highway. There has been a recall on the police vehicles for the same issue which turns out to be alignment issues. I am fearful for my safety in this car along with the expenses being incurred due to a poor quality product.

The contact owns a 2007 Chevy Impala. He stated that when snow and ice are on the road the rear end of the vehicle would slide "very dangerously". while driving at speeds of less than 30 mph, the rear end of the vehicle would swing outward whenever he would drive over a sheet of ice, snow or during inclement weather conditions. The dealer stated that the tires needed to be aligned and rotated. No repairs were made to date. The failure and current mileages were under 104,000.

The rear tires are wearing terribly on the inside. Significantly more so than any other part of the tires. I had a rear end alignment done on the car, and it was no help at all. I then replaced the tires at 40,000 miles and the same thing is happening. After researching, I found that many police Impala's have this issue, but mine is having the exact same problem.

Only the inside 1 inch of both rear tire wear out after 15,000 miles down to the cords. General Motors has replaced two sets of tires for me but the second I hit 36,000 mile warranty they refuse to help me anymore. There is a program bulletin from General Motors on this defect (bulletin number 08032) for the police package vehicles only. I looked up the defective part numbers (10329689 & 10329691 -rod & rear spindles) and they are the same part whether they go on police vehicles or the common consumer vehicle. Defective is defective. I have argued with General Motors and they refuse to help the common people who buy the majority of their Impala vehicles. No matter how many times I take it back to the dealer they can't line up the rear end to stop the wear. Someone is going to blow a rear tire and have a fatal crash!

I purchased 2007 Chevy Impala with 32,000 miles. I bought this at a GM authorized dealer. How can they sell a car with an alignment issue. At 40,000 miles the inside of the rear tires are almost bald. I called GM an got a case number of 71-686232146 they stated that I would have to go and pay a dealership $100 to do a diagnostic on the car and they would then at that time do a review if they would cover the repairs or not. Upon researching on the internet I have found several other people with the same problem on this car. GM is admitting this is a problem on the police version of the car. The part numbers for the spindle rod is the same on both cars. I believe GM isn't fixing civilian cars due to we don't have unlimited money and lawyers like the city, state and government. I noticed this on Tuesday December 9th 2008 on an icy road. At 30 mph, it feels like the rear end wants to pass you or like as if you where pulling a trailer that was violently wiping back and forth. When I went from dry pavement to icy pavement the car went sideways. I had made an appointment with country side motors in wellington Kansas 67152 phone 620-326-7433 and spoke with the service manager ron. We made an appointment for the next day. He called me back 15 minutes later after looking at the recall for the police version and said he didn't like my attitude the last time we talked on a different issue "it was about the tire pressure monitoring system being off, he said my tire were over inflated and to not go by what the tire manufacturer says but go by what GM says to inflate to. I told him not so and an example of it was Ford also thought they knew better than the tire companies and they were wrong too." So he told me that country side was washing their hands of me and my issues and hung up the phone. I believe this to be a serious safety issue with the car. A person could involuntarily swerve and hit an oncoming car. The parts are $250 plus install and new tires.

I bought a 2007 Impala with 16,000 miles on from a small dealer in May 2008, it was a previous rental vehicle. Soon after that, someone brought to my attention that the top or the rear tires seemed tilted toward the vehicle and the bottom tilted away, (out of plumb). The vehicle seemed to drive fine so I thought it was normal for this vehicle. At about 25,000 miles I noticed the inner sides of the rear tires showing excessive wear, at 28,000, the tire belts were showing on the inner 2 inches of the tire. The outer treads look great. I contacted the dealer that I bought it from and they said that it was an alignment problem and that I should contact GM as it should be under the factory warranty. I'm now waiting on an appointment with my local GM dealer next week. After researching this on your web site I'm seeing a real problem with this. I too fear for the safety of me or anyone else that might have this problem with their 2007 Impala. I have not confirmed if this is a recall issue or not, but it should be. Please help!

I have a 2007 Chevy Impala. Bought it in Nov 2007 with 13,000 miles. I noticed all winter driving on snow and ice., that it was handling terrible, was swaying all over. Contributed it to the excessive snow. In May 2008 my check engine light was on took it to the dealership and then was told both of my rear tires were worn down on the inside down to the metal. I now have 19,000 miles on it. Rear tires had to be replaced and an alignment. I ask how this could happen with so few miles. I was told " that it just happens" no it does not just happen. The rear wheel spindle rod needed replaced and this caused the tire wear. The dealership would not work with me at all and I had to pay for all repairs. I found out that their was police vehicle that this happened to and GM paid for the tires, because it was a defective rear wheel spindle rod. I contacted GM customer servi ce and was told that they replaced the tires on the police car because it was known to go bad on the police equipped vehicle, .and of course it shouldn't matter, a 2007 Chevy Impala is the same no matter if the police are driving it or if I am. I got no where with GM, in fact I was treated very rudely by the customer service manage. I am still pursuing it. Everyone who has had this problem, should continue to pursue this. It is not right, we should be compensated for this.

A friend a mine told me I needed to check the rear tires on my 2007 Chevy Impala. He stated that he knew of several cases that the inner rear tire had severe tire wear and could cause an accident. I check my tires and found that both rear tires had been worn down until the steel belt was visible on the inner two inches of the tires after only 20,000 miles. The front tires also had worn on the inside two inches of the tire. I contacted the dealer where the vehicle was purchased and told there was no recall or service bulletin and the problem was I did not rotate the tires properly. After calling several other dealers and GM customer service the dealer where it was purchased told me to bring it in to be checked. When I arrived before the service department even looked at the vehicle, I was told there was nothing covered by the warranty and there was nothing they could do. I was told by the service department that my vehicle was not safe to drive home due to the tire wear. I was told by the GM customer service it was not there problem, case closed. I did learn after some research the GM has a problem with the 2007 Chevrolet Impala police vehicle. 'a condition that may cause rear wheel misalignment, resulting in lower tread dept on the inner side of the rear tires'. GM will 'replace rear wheel spindle rods, align the rear wheels and if necessary replace the rear tires at no cost. GM has admitted they have a problem with the police Impala but not any other models of the Impala. Before this causes accidents GM needs to come out with a recall to fix all of the Impala.

Rear end alignment on fleet vehicles. I currently operate a 2007 Chevrolet Impala as part of my employment at a local police Agency (government vehicle). At my last oil change, at 10500 miles, I was shown my tires on the rear (bald on inside) and told I had to bring to the dealership for warrant rear end work. I was told at the dealership this is an issue with all fleet vehicles of this make and model but not a recall. They are supposedly fixing my rear end but are refusing to replace the tires. Tires should not need replacing at 10,000 miles, so it is a defect and should be warranty. Also, due to the type of wear on my tires, it was not visible until removed from my vehicle (outside tires still had tread) which I believe is a safety hazard as the tires could malfunction during a high speed incident and cause harm to me or my co-workers.

- Baton Rouge, LA, USA

Rear alignment not within specs from factory, caused rear tires to wear out prematurely. Front disk brake rotors and brakes unrepairable at 11,000 miles. Chevrolet would not cover repairs under warranty.
