When first purchased I had to change accelerator pedal. When I took it to the shop I was told they get a lot of people w Impala same as my year 2008 that needed to have the accelerator pedal changed every so often because they would go out and it would cause the check engine light to go on and off because the vehicle was sending the wrong signals.I would drive on the highway and street it would cause reduced engine to come on and slow my car down almost leading into accidents because I did not know it was about to happen. It would come and go on as it wanted. The electrical part of the car is something in the car continues to drain my battery. I've gotten a new battery and it still drains causing me to have to get it recharged. The suspension I was also told for the year of my car is bad. When purchased I found out that again people that purchased these years of vehicles had problems with the control arms and that I now have to take it to get fixed because one hit to a pot hole can cause the under part of the car to break and cause a bad accident. I did not know Impala had this many problems. I seen the police Impala for 2008 were recalled for suspension, but they all seem to share this common problem as well as the actuator continuously clicking. It seems to be an easy fix, but I shouldn't have to fix something that is a common problem for the Impala.

The stabilitrak is making the car shake and act crazy. I'm barely in control of the car. There are thousands of more people having the same problem. The car reduces speed because of this issue. Many groups and blogs online about this. Why hasn't anything been done about this? no recalls or anything.

I have replaced bushings 3 times, struts front and back, shocks and sway bar pins 2 times. I drive city roads to work only 5 miles from my house. I only have 77,586 miles on my car and a lot of problems for that type of use. We have a 1998 Chevy Tahoe that we love. You should stand behind your bad products that you put out.

One day I was driving my car home making a right turn and my engine started making noise and was acting as if it was going to cut off. So I parked my car called my mechanic he came over and looked at the car I said it could be a possible rocker arm that has gone in the car or I could have something to do with the check engine light coming on giving me a code for a cam positioning sensor / solenoid. Also when I purchase the car not too long after me driving I noticed there was some noise coming from my back tires. I couldn't figure it out for a while until one day I looked at my tires and noticed that on the inside there was a considerable amount of scraping going on wearing away my tread. It would always seem to happen when I got new tires on the car so I thought maybe the tires were too big for the car but I ordered what the manufactor suggested the tire size should be for the car. So I had a tire specialist look at it and an alignment specialist look at it and they told me that the suspension springs may be causing my issue. They said that I should not have to change the size of my tire for them to fit because the manufacturer specifications are correct and the tires were the right size for the car.

2008 Chevy Impala ltz -- I am having trouble with the rear inner tires wearing down to the chords just like all the other complaints on here. I know it's not the tire brand, etc. As I've had a reputable mechanic put on two sets of tires. I found articles on a lawsuit and the fact that GM will fix the police cars with this issue, but not the general public's. I bought this car as a commuter car for my sons that will be college students and I need it to last. I want a copy of the tsb #08032A that addresses this issue. I just want my car fixed so that I don't keep blowing through sets of tires it is getting ridiculously expensive. My last set was supposed to wear out at 60,000 and only lasted 20,000. I am actually on my second set, so basically $1600 into tires alone, not to mention what it's going to cost me for the spindle/cambor/rear tie rods that is associated with the tsb mentioned above. GM should be paying for this and it should be a massive recall. These cars are prolific in society. Lol....we bailed them out in 2008, and they were cranking out lemons the same year....ironic!! GM refuses to take responsibility.

I am informing you of some very serious concerns in regards to parts of the 07 and 08 Chevy Impala that have failed causing accidents as well as injury and grave potential for fatalities.airbags not deploying, seat belts not locking on impact first and foremost I have requested copies of the paperwork that was submitted to the courts in somerset wi. This showed exactly what took place causeing an accident that was considered negligent due to medications I was on and my disability. The mechanic gave me this report along with info stating that this was a huge problem in fleet police vehicals. The info stated that the police vehicals were fixed and checked however this part has no recall or revision to correct the safety issues that we can find. My vehical does have high millage however it has been very well taken care of thanks to erickson oil and mechanic friends. This part snapping after cracking esily resulted in complete loss of control as well as the car locking up and becoming impossible to steer and stop. It is disturbing that these parts were not corrected from a manufactering aspect (this was looked at by a machinest, as well as an engineer and by the qaulity/dimesions/structure this part easily looked defective) the visual as well as skilled aproach to problem solving drove us to look up recalls prior to buying a new part. We could not find any. Just info that this exact make and model were purchased as fleet vehicals in 07 and 08. Problems with many of these cars resulted in pulling all of the fleet/govnt patrol cars in to be fixed/investigated. However we have been unable to find a recall or warning that should have also been issued to the public. I am currently looking into help to investigate and help get this looked at as it caused an accident as well as being unstable and faulty in another minor impact accident potentiaaly increasing fatality/injuries.

Subject: 2008 Chevrolet Impala rear tire wear. Case # [xxx]VIN # is [xxx] we are having a problem with our 2008 Chevrolet Impala. Our rear tires are wearing out twice as fast as the front tires. I went to costco yesterday to have my tires rotated, after looking at the rear tires we had to buy new ones because the back tires were worn down to the metal backing, the front tires were still good. Only one half of the warranty had been used. The tires were Michelin X-radial dt mich passenger S/T P225/60R16 bw mspn 17457 tires with an 80,000 mile warranty. We ended up buying four new Michelin tires for around $600. The costco guy thought that something must be wrong with the car. After I got home I checked on the internet as to what could cause this problem and found out that there was a problem with the 2007 and 2008 Chevrolet Impala's. there had been a service bulletin #08032A sent out in 2011 to replace the spindle rods on all the 2007 and 2008 Impala's that were sold as police cars to fix this problem that they were having with rear tire wear. I would like to see that service bulletin extended all the other 2007 and 2008 Chevrolet Impala's. the part number for the spindle rod is the same on all 2008 Impala, police or non police. This is a major safety problem and people are going to be killed if this problem is not fixed, you just don't expect the tires to wear out so fast. We had just finished a trip were we drove freeway speeds up to 75 miles an hour. After seeing our tires I don't know how we keep from having a blow out on the back tires. I think that lots of accidents have happened with these 2007 and 2008 Chevy Impala with tires blowing out because rear tire wear because the spindle bolts are engineered wrong and every one thinks its the tires fault.. GM needs to fix this problem and replace the four spindle bolts. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

We would like to forward more documentation for assistance as ftc is telling us you can assist hold fowler Chevrolet of tulsa Oklahoma accountable. This is a serious safety issue also if they are repairing cars that should be a total loss besides compensating us for the financial issues related.
