| The first instance i was driving and the service brake system flashed on the display. i had all brake pads replaced at dealer on 1/3/2013. 2/7/2013 i was in traffic and the car suddenly slows to about 10 mph and would not accelerate the dash then displayed reduced engine power and the check engine light came on. on 2/14/2013, i had the throttle positioning sensor replaced and at the same time had the rear defrost wiring repaired because that had not been working for over a year. on 3/4/2013 the car would not start by the factory remote start, so went out and started the car with the key, when i returned to the car the vehicle would not start at all the chime would sound the lights on the dash flashed but no start. i waited a few minutes then tried again, the car started briefly (50 seconds) reduced engine power appeared on the dash then it shut down completely. i looked under the hood saw the battery attachment was loose, tightened that up and then the car started up. however, the car radio (factory radio never replaced), the chime, or the ticking of the turning signals no longer work. i have an appointment with dealer on 3/14/13, but the car seems to be failing all around. in reading chevy/gm forums, there are thousands of chevy owners experiencing these same issues, chevy/gm needs to take ownership and investigate these vehicles to determine the root cause of the problems. nearly 3000 dollars later in dealer repairs is not getting to the bottom of the issue. i was nearly in a crash due to the reduced engine power issue and that was scary enough to make me not want to drive this car or an at all. | |||

| I have not had an incidence but very concerned about the malfunction that is going on with my vehicle at this time..i noticed a scrubbing/grumbling noise when i would turn the wheel either way left or right. after vehicle being put on machine for testing it was discovered that the upper strut mounts and bearing were worn and noisy on front struts......also my abs and traction control light both came on at the same time and would not go off, the information system in vehicle recommended brakes be service.....the results from car being tested showed both front hubs have slack and both front wheel speed sensor harness are coming apart inside wire installation. the codes for abs/traction control is...c0040 00.c0040. *tr | |||

| I purchased the vehicle with 704 miles on it in february 2008. in may of 2008, the traction light came on and the traction control and abs were disabled. i took the vehicle in to the dealer where i purchased it, and they told me i had water in the fuel. as i was leaving the dealership, the transmission stopped shifting, and the car went into limp mode. i left the car to have the transmission control module replaced. i received the car back 5 days later and the light came on again, and the abs and traction control where disabled. i took the car to another dealership in the hopes that they could find the trouble. after 14 days in service, they determined that rust has clogged the fuel system of the vehicle. the vehicle currently has 9,800 miles on it. the car is now undriveable. they have yet to address the root cause of the safety issue that was the catalyst for the service visit. *tr | |||

| I will not drive this car down any steep grade. going down cuesta grade and applying brakes, the steering wheel shakes uncontrollably. we had the car checked out at a dealer and they said it was probably the rotors. we then had them turned front and back and got a front end alignment. that did not change anything. we then had a four wheel alignment done and replaced the brakes. no difference. that is when we were told we needed to replace our tires. the rear were wearing out at very fast. they lasted under 20k miles. we are now on our third set. it's too bad gm will not recall 2007/2008 impalas. only the police version.this is not right. our rear spindles and front upper/lower control arms should be replaced at no cost to us. if not who would bother buying this car when we sell it? *tr | |||

| I own a 2007 impala lt 3.9 l. purchased from sunset chevrolet in sumner, wa 1/03/10. not even 3 months after buying the car, the engine oil started leaking, the transmission started leaking, the power steering started making an abnormal noise, and the car needed a brake job. (front and back). took car to dealer (burien chevrolet in burien, wa). was told that the needed repairs were not covered by warranty. we declined repairs as we could not afford out of pocket cost. contacted general motors. was told that at the time the vehicle was taken to the dealer, that relevant components were indeed covered by the warranty. gm was unsure of why dealer had told us they were not covered by warranty. but that the warranty was presently expired, and even though it wasn't when we took car to dealer, there is nothing they can do now that the warranty is expired. also, the tech at burien chevrolet said that he could see no signs of the symptoms that we described were wrong with the transmission, even though there was a service bulletin issued by gm on 10/15/09 (06-07-30-023c) which describes the symptoms exactly as we told the dealer. it also contains information neede to repair the problem. now the transmission is on the verge of breaking down and the engine is leaking oil more than ever. | |||

| Have had issues with warping rotors on a 2007 ltz with only 50,xxx miles on it. this is a safety issue as the inferior product (gm brake rotors) make the car shutter and shake, which causes the driver to almost lose control. this has been going on for too long gm. my 2003 silverado has the same issues with the brakes. gm - read your customers reviews and fix this problem! i for one like to buy american, but have since considered a different route since my family's safety is being compromised with the inferior brake components that gm has in their vehicles. | |||

| I noticed that all of a sudden when i would try to stop my car would shake or hesitate to stop. i thought it was my brakes. after trying to park and the brakes not stopping at all. i took the car to repair shop to be fixed. first i was told it was the master cylinder after replacing that the car still would not stop. so i was told it was the hydraulic abs system and that all the brakes and rotors needed to be replaced. the dealership doesn't have the part it is on backorder due to the high volume of the part. that says to me there is a problem that checy needs to be responsible for and correct before a serious accident happens. | |||

| Severe vibration from the front brakes of my 2007 chevrolet impala. occurs at speeds above 50 mph, particularly sever when stopping ~70 mph. car did this at 40,000, replaced front rotors. again at 80,000 miles, again replaced front rotos, now again at 100k miles. | |||

| I have a 2007 chevy impala with brake and tire issues. i have owned this vehicle since it was 2yrs old with about 32,000 miles on it. in the first year of owning it i had to replace brakes rotors due to warping four times and tires due to pounding three times. after filing a complaint with chevy on their web site and getting no response and seeing other web based complaint site with similar complaints, i am sending this to you. chevy tells me that these probelms are caused by hard braking which isn't the case, i have been driving the same way for over 25yrs and have never had this problem. after spending thousands of dollars to try and correct the problem i gave up and have been driivng the vehicle the way that is for awhile now. recently because the tires were pounding so much and the brakes shaking so much at highway speed, it was hard to control the vehicle. i had to replace the rotors again which started pulsating again within a thousand miles or so. i have talked with other impala owner and have heard similar complaints and chevy doesn't seem to care. this can be a real safety issue at highway speeds and replacing tires and brake is only a temporary cure. chevy says that i should do a road force balance, at $70 per, every 3,000 mile to correct the tire pounding issue. they have no solution for the brake issue other than to not use the brakes i guess. | |||

| I own a 2007 chevy impala that when brakes are applied the steering wheel sudders. this happens after moderate to heavy braking or during down-hill braking. the driver gets a sense of losing control of the vehicle and tends to reduce braking which may lead to an accident. | |||

| Front rotors are warped at 22,000 miles on the car. it appears that the rotors are either undersize, made of poor steel, and or imported from china. there is no reason for the rotors to have failed and be resurfaced. as a mechanic this condition caused a significant safety issue under highway speed braking to a stop. my wife thought it was the road but instead it was a rotor shimmy. i thought the car was going to shimmy apart and brake steering tie rod links at the time it happened. there was no way i was going to let up on the brake or i would have hit the car in front of me. instead i rode out the violent shimmy and grinding sounds coming from the front end. the concern i have is that other people would not identify the shimmy for what it is like my wife did and think it was the road. i feel that if the road was wet i would have lost control of the car. *tr | |||

| Front disc brakes make a grinding noise when applied especially going downhill. rotors and pads are in perfect condition. dealer said that they are noted for this problem yet they will do nothing to correct as there is plenty of pad left. noise is very bothersome. it sounds as if the pads are worn out and starting to grind into the rotors. this is definitely a factory defect and gm should offer a new type of pads to eliminate the noise! these are the factory original pads on the car. *tr | |||

| Shaking from front end when brakes applied. can be very violent when going downhill. seems to be common amongst impala's, dealers refuse to cover the brakes. i just bought it second owner at 25,000 and it even went through gm certified with this shaking brake problem. *tr | |||

| The brakes were applied while descending a steep grade. the front end of the vehicle started shaking violently. when the dealer was contacted they stated it was probably warped rotors and they probably need turned. this will be the second time those rotors will be turned. this is always the manufacturers cure for this problem. it's just a delay until the vehicle runs out of warranty in another 5,000 miles. i've had this problem with warped rotors on various vehicles before and my experience has been that it never fixes the problem. because this is a known on going problem which occurs on all makes and models of vehicles and also because it happens to one of the vehicles most critical systems, the practice of turning rotors to solve rotor warping or rotor shudder problems should be banned for all vehicles. *tr | |||
