Tl- the contact owns a 2008 Chevrolet Impala. While the vehicle was parked the contact inspected the rear tires and noticed the tread was excessively worn. The vehicle was taken to the dealer for diagnostic testing . The technician was unable to diagnose the failure. The contact stated the failure was caused by the rear suspension and stated the manufacturer voluntarily recalled police vehicles only for the same failure. The vehicle was not repaired. The approximate failure mileage was 71,000. Rvk.

I have a 2008 chevy Impala, at 23,000 miles the tires are bald. I rotated them every 5000 miles. I bought this car brand new in late 2007. From reading the other forums on line, it's not the tires. It's the rear end alignment from the factory. This tires are going to cost $1,400. 00 to replace and I'm being told the new one's will wear out just as fast as the old one's. I see there's a class action suit agains't gm for 2007 & 2008 Impala's. They fixed all the Impala cop cars but not the general public!.

Purchased 2008 Impala ss factory demo car with 3000 miles and at 15000 miles a rear tire blew out at 65 miles an hour and almost wrecked us. Rear tires were wore out on inside. Down to the cord which at 15000 miles seemed impossible. Replaced tires and dealer said alignment was not the problem but was normal for the model car and now at 23000 miles rear tires are wore out again on inside and front tires are the original and still look new. Why can't the dealer repair the problem instead of selling tires every 10000 miles? I think they just want the extra cash flow during this time the economy is slow .

My family was traveling to a funeral driving a 2008 Impala at 75mph. Tires were properly inflated and visually checked for wear by general observation. Tires appeared to have plenty of tread and no cupping. Left rear tire detonated sending tire tread/belts/debris into wheel well area. This ripped fuel filler assembly loose and sent it below car where it trailed with no remaining fuel cap and frayed sensor wires exposed. Car was brought to a safe stop beside interstate. When trying to make temporary repairs it was noticed that opposite rear tire had wear down to steel belts on inside two inches. The remaining tire appeared almost new from exterior view. It was replaced along with blown tire as this tire was just as deadly. Repair by insurance exceeded $4,000. Contacted Chevrolet dealer where vehicle was purchased and have not received a response. I believe this is a potentially deadly service issue that needs to be addressed so that repairs to rear suspension can be made. Most people are driving around totally unaware that their tires only appear safe. Unless the car is put on a lift rack the wear issue is not obvious to the average automobile owner.

I have experience rapid tread wear on the inside of my rear tires. Last set of rear tires were worn down to the steel after approx. 18. 000 miles. Current set of rear tires have approx. 12,000 miles on them and are showing significant wear on the inside. A day ago I was driving on a rain covered interstate early in the morning. The rear end of the car swung out to the left and I lost control and spun around 2 times ending up in the grassy median. Luckily, no one else was near me when this happened and no damage was done to the vehicle. Currently, I am trying to get gm to repair the problem which I believe is the same problem that the 2007-2008 police vehicles were recalled for.

2008 chevy Impala has premature loss of tread on both rear tires front tires do not show any noticable tread wear but rear tires have lost all of inboard tread. This is a defect in either the wheel mounting or suspension system causing unsafe operation of this vehicle.

I am experiencing excessive inside tire wear on my rear tires and apparently it is a common problem with 2008 Impalas. 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 Impalas 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.

The contact owns a 2008 Chevrolet Impala. The contact stated that both rear tires were wearing excessively. The vehicle was taken to an authorized dealer where the tires were rotated. The manufacturer was made aware of the failure, but offered no assistance. The failure mileage was 23,000 and the current mileage was 26,000.

Purchased new 2008 Impala, had to replace tires at 35000. Always rotated and balanced and kept proper pressures. Now at 56000 and am being told by chevy 1800. 00 to repair rear alignment. Car is driven 99% on the interstate. Again need new tires whats up??? chevy denies any problems but the web is full of issues surrounding this. Is there no other recourse????.

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.

We have a 2008 Impala, we had to have new rear tires at 24,000 miles and realigned. My tires were so bad it almost did not pass inspection. That is how I found out about the tires being bad. And now I hear that others are having the same problem. I have the before and after measurements.

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.

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 Impalas that has fostered numerous complaint to you including 5 already this year. Gm issued a TSB #08032 for police Impalas 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.

I own a 2008 chevy Impala and have had extensive work don on the car to reapir the alignment of my rear tires. I first noticed the issue when after roughly 7000 miles I took my car in to have the tires rotated and I was informed that my rear tires had the steel belts showing. This was a shock because I had purchased 80000 mile tires. I then took my car to my local mechanic who fixed the problem to the best of his ability and this plus the cost of the tire ran me roughly 1000 dollars. Prior to me getting the car in to the shop I had noticed extremly poor handling in the snow, bassicly it felt as if the rear of the car was constantly slidding out.

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.

I own a 2008 chevy Impala ss, I bought the car in October 2008. Since buying the car, I have had to buy 3 sets of back tires due to excessive wearing on the tires. I have had my tires re-aligned everytime I have had to put new tires on the back, yet they continue to wear out extremely fast. The first set of tires I had to put on the car was in March 2009, then again in may 2010 (of which I needed new back tires prior to then but could not afford to buy them until that time), then I had to replace them again December 2010. I am now on my 3rd set of back tires, and am needing to replace them yet again. I have just recently learned that there is a law suit currently filed against gm, stating that there is a defect in the rear alignment spendle causing excessive wearing on the rear tires. Per the news reporst on the law suit, it is requested to become a class action law suit as gm issued a letter for the police Impala's to be repaired and for the owners to be reimbursed for any tires bought, however they neglected to inform the public who own 2007 & 2008 Impala's with the same problems.

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.

Previously filed complaint in 10/2009 gm offered $1000 voucher for the problem. Turned vehicle into dealer in sept 2009. Told gm that I would make payments until Jan 2010 and to provide a solution to making our 2008 Impala safe to transport my family. They refused to address the problem and the car sat at dealers until may 2010 when a collection company called my home and I tolld them the story. They asked where the car was and I told them. They put me on hold and called the dealer to confirm. That day they went and picked up the vehicle and started sending collection notices. I told them car was unsafe to drive. They sold at auction and sent me to a collection agency for the balance of $9700. The car resold to an unsuspecting customer in nh. Gm is still trying to collect the balance and has offered a compromise $4800. These vehicles have killed unsuspecting comsumers but documentation does not exist?? I am sure if a study was done on all highway /accidents/deaths connected to 2007 & 2008 Impalas, rear tire wear would be well represented. Gm should smell the coffee and recall these dangerous vehilces. It appears to be a specific frame run and not every chevy and Buick frame manufaxctured in those years. All police vehicles have been recalled and retrofitted to correct the rear alignment issue please help protect american consumers and force gm to make this problem right!.

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.

Tl - 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.
