I have a 2008 Chevrolet Impala. I purchased 4 new tires for the vehicle. Within a few months, I noticed that both rear tires had a strip approximately 2 to 3 inches wide worn completely bald. The strip was on the inside of the tire, moving towards the center of the tire. The wear strip was so bad that the tires were useless and needed to be replaced. This defect was not a tire issue, nor a driver issue. The vehicle is driven by adults.

The contact owns a 2008 Chevrolet Impala. The contact stated that he had to repair the front end alignment excessively due to the rear spindle. The failure caused the rear end of the vehicle to move. The contact replaced all four tires at 17,000 in September 2009. The dealer advised the contact that the tires had worn, and that the front end alignment could wear easily as well. The manufacturer was aware of the failure. The current mileage was 40,000. The approximate failure milage was 10,000. Updated 08/22/11 updated 3/06/2012

The contact owns a 2008 Chevrolet Impala. While driving approximately 5-25 mph, a loud thumping noise emitted from the rear end of the vehicle. The failure occurred when driving at low speeds. The vehicle was taken to the dealer where the four tires were rotated and the failure continued. The technician advised both rear tires would need to be replaced. The contact stated the inner tread on both rear tires exhibited an uneven premature wear due to defective spindle rods. The manufacturer was not made aware of the defect. The approximate failure mileage was 20,000.

The contact owns a 2008 Chevrolet Impala. The contact stated that the rear tire had excessive wear due to a faulty rear suspension. The contact took the vehicle to the dealer, which stated, the bearings on the rear axle needs to be replaced as well as a wheel alignment. The contact had the bearings replaced and a wheel alignment but that did not remedy the problem. The contact stated the vehicle was unsafe to drive during inclement weather. The failure mileage was 30,000.

I am experiencing excessive inside tire wear on my rear tires and apparently it is a common problem with 2008 Impala. I spoke with customer service obviously not in this country, and was told I would have to pay to inspect my car. I then spoke to a service manager who denied any known problems. He then let it slip that a modification of the struts was necessary to achieve proper alignment of the rear and that GM would not cover it. They will however repair police Impala at no charge. I declined to pay only to be told I would have to cover the cost of repair anyway, kind of like adding insult to injury. When will action be taken to prevent accidents due to blow outs; which apparently have occurred? not everyone looks under their car to inspect the tires and this wear is not visible otherwise. Customer service was not fazed in the least that I might buy elseware, her comment that is your choice, so much for service.

Severe inner surface tire wear on rear wheels of 2007-2008 Chevrolet Impala vehicles. Technical service bulletin 08032 is on file with General Motors, acknowledging the problem, but willing only to pay for necessary repairs to police vehicles, when in fact the flaw exists with all 2007-2008 Impala vehicles. We purchased the car as a demo model in 2009 and were not made aware of the problem. We believe the dealer was honest, and also not aware of the problem at the time. We believe this to be a safety issue as well, since handling on wet roads is effected due to the fact the rear tires are contacting the road surface only on 1-2" of the inside surface of the tires.

Had to replace rear driver's tire at 17,000 miles due to wear down to the metal. Took the vehicle into the dealer to check wheel alignment and found the rear so misaligned that the adjustment struts had to be elongated. Spoke with GM customer service rep and was told this was not a warranty issue.

I own a 2008 Chevy Impala which I had new tires installed. I also had an alignment done. At my first tire rotation (6000 miles) I was told of excessive wear on the inside of the rear tires. The wear is very obvious. The tires are a 60,000 mile tire(uniroyal) after contacting the place that aligned my wheels.(ase certified) they did some investigating during which they found GM recalled "police package) vehicles with VIN#S falling in a specified range. Which my car also falls in this range. They had defective spindle rods in them, however as a consumer and not a "police" vehicle GM tells me I am responsible for having the proper work done to have my car fixed. Upon searching myself I have found numerous "consumer" complaints regarding premature tire wear on these vehicles. I see this as a considerable safety concern that the manufacturer should be held accountable for regardless of whether it is a civilian or police vehicle.

On 2008 Chevy Impala, the insides of all four tires were worn to the cord. The tires had been rotated regularly. The car was returned to the dealer who claimed the tires had not been rotated and that he had never heard of any defect.. we printed information from this website showing that this problem had been reported several times. The dealer still denied any defect even though one of the workers said he had replaced tires with the same problem.

2008 Chevy Impala was shipped from the factory unaligned causing premature tire wear. There may be a camber related issue causing premature wear on the inner edge of the rear tires. Problems start at about 10,000 miles. I replaced the rear tires twice in one year.

Started having issues with my 2008 Chevy Impala with what I thought was a tire balance problem. Did required tire rotation as recommended at 6000, 10,000 and then again at 13,500. Dealer said tires may be out of round and suggested road force balancing at 16,500 miles. This did not change the issue, so went to Goodyear dealer and found out that the inside 2 inches of all four tires were wearing excessively with the rear two less that 2/32 inches of tread left. Goodyear shot the alignment and showed that the alignment was way off and tires could not be warranted with an alignment issue. Took back to Chevy dealer to inform them of the alignment issue. They said alignment was not warranted after 7,500 miles and also would not replace the 4 tires. I did get the dealer to gratuitously do a 4 wheel alignment that also showed the camber and toe, especially in the rear was "out of tolerance and exceeded cross-tolerance" on their machine as well. The camber could not be adjusted without extra work (elongating the bolt holes or a chamber alignment kit). Contacted GM complaint line for resolution to no avail, saying I had to prove that there is a defect on the vehicle. This is an inherent safety problem with 2007 and 2008 Impala that has fostered numerous complaint to you including 5 already this year. GM issued a tsb #08032 for police Impala that are on the same platform and suspension, but never extended that to the public. Seems to me that the rear suspension has an severe defect that can cause tire blowout without warning. No tires should wear like that with less than 17,000 miles without a rear suspension and alignment problem that needs to be recalled for repair and replacement of the parts and tires. I saw at least 12 complaints in the first 24 pages of 2007 Impala complaints to the ODI. Please investigate this problem before someone is seriously injured or killed as a result of this continuing Impala issue.

During any damp, wet or snowy roadway conditions, my 2008 Chevy Impala ss handles dangerously poor. This occurs even if the car is put into neutral driving down the road. The rear-end keeps wanting to go sideways. I took it to a Chevy/GM certified dealer and they said that there was no problem with it.

My 08 Impala ss has been going through tires excessively. I replaced the back tires almost 4 months ago and new tires are needed again. The rear tires are wearing on the insides of the tires. I brought this to the attention of my local GM dealer who "assured" me that nothing is wrong with the rear suspension and that I need to rotate the tires every 6000 miles that was what was wrong that I wasn't following the owners manual. So I thought it really was my fault so I spent the $500 to buy two new tires and now almost 4 months later the same thing is happening. I have only put about 6000 miles on the new tires and the cords are already showing on the insides of the rear tires.

GM issued a letter to 2007 and 2008 Impala police vehicle owners concerning a condition that leads to rear wheel misalignment, resulting in excessive wear to the inboard side of the tires. My 2008 Impala ss is exhibits the same problem, but GM will only fix police vehicles. My complaint is that the problem effects more that just the police vehicles because the rear suspensions and setups are identical. GM should fix any Impala experience the alignment issues because they were never right to begin with.
