| Brakes had to be fixed three times under a defect. no notice was received by dealer. a local dealer let me know to bring the car back to dealer to be fixed. by the last time the brakes were fixed, warranty was out. brakes should have been fixed for free due to defect in rotors. now there is a problem with the steering and no safety recall notice has been received, but read about it online. *tr | |||

| Speedometer said i was doing 87 mph when car was shut off and in park. took car to dealer, had instrument cluster replaced. also had them check pop in the steering( made noise when i bought it from dealer with less than 31,000 miles on it. dealer replaced instrument panel cluster, steering shaft and cruise control sensor. ( cruise control would just shut off and work periodically.) it was really just an adjustment on the brake sensor switch that needed adjustment. had to take car back for the adjustment to brake pedal sensor. *tr | |||

| My chevy impala began shaking when i attempt to slow down on the freeway from speeds of 55-65 miles an hour. i have replaced the tires, brakes, and balanced, aligned, rotated and the shaking has not stopped. this is very dangerous when you need to come to a quick stop because when your car shakes like it's falling apart your first instinct is to let go of the brake. i have researched this problem and have come to discover this is a common problem with chevrolet impala's. i can not afford to keep dumping money into a temporoary solution. | |||

| No events appear to lead up to the problem. it occurs randomly without warning, especially during backup operations. the abs seems to come on whenever it likes during braking, causing heavy loss in stopping power. this can occur regardless of road conditions or speed. similar to this, the traction control system appears to come on during acceleration at random times, especially at low speeds or in reverse. this occurs on dry roads frequently and occasionally causes the vehicle to pull heavily to one side as neither side is actually slipping. an accident has not yet occurred but certainly can given the nature of the failures. a tsb is available concerning the abs. this vehicle has a whopping 75 tsbs! service bulletin number : 4615 nhtsa item number : 10023171 | |||

| 3.4ltr 6cyl base model has had multiple defective sensations for some time now; among those are steering, transmission shifting from a standing stop, braking and odd noises. this vehicle's 5 y/o with only 20k mi, owned by elders & used locally, i've been driving them, & now i have this car. the left outter tie rod end had to be replaced with less than 20k mi. the steering still has an unstable feel when turning and make a metal to metal clinking noise from a defective (& as told by my mechanic & nhtsa reports, repeatedly reported) intermediate steering shaft. there should be a total recall because of this defective gm engineering problem. there is also a clinking noise occasionally when accelerating from a standing stop; can not tell if this defect is from the steering or something else like the engine mounts. have not yet discovered this source. from a standing stop, the transmission will occasionally shift abruptly, either from a neutral disposition into 1st gear or from 1st to 2nd gear; the car lurches forward & the occupants heads are whipped back. this is similar to other reports of defective power train functionality i've read about with this model. braking, when just starting a trip, has an improper feel and sometimes sounds like it's grinding, as if the brake pads or rotors are cracked/worn; this is a sensation i've had with vehicles having 100,000 miles, not on a car like this with only 20k miles. the center arm rest's pad support is flimsy/cheap plastic & has broken simply upon entering & shifting in the seat. i now see why so many police departments have discontinued the impala's in favor of the charger's, crown vic's, taurus's and escapes. the us government should be severely fining gm for marketing this car. >>>this car needs to be recalled for many reasons<<< | |||

| Traction control system failed on my vehicle. the failure turned off my anti-lock brake system and my traction control system at two inopportune times. this failure has twice in the past few months. it first occurred at the end of december during a snow storm. the second failure occurred a few weeks ago while driving through a rain and hail storm. both times the vehicle was taken to the dealership to be fixed. the dealer replaced a faulty speed sensor. my car is about a year old and two speed sensor have already failed. i'm upset at the fact that we purchased the car based on its safety features and twice now they have failed, as i mentioned earlier, at the most inopportune moments, where we were relying heavily on said safety features. *nm | |||

| I have a 2005 chevy impala, currently with 22,320 miles. at my oil change and tire rotation, (~20,500) i was informed by repair place that they would not perform the tire rotation as i would be needing to replace the tires soon. i asked why they were wearing so fast- i was told, they noticed it on many impalas- premature tire wear between 18,000-25,000 miles. ~ 15 months ago, with only about 13,000 miles, when i had an oil change done i was informed me the engine was leaking oil from the rear of the engine, i should take it to the dealer for repair. the dealer had to replace (under warranty) several seals/gaskets- oil pan, drain plug, oil filter, plus replace the drain plug. the car is sometimes hard to start and have to hold the key in the start position, and/or lightly press the gas pedal to start it. about two weeks ago, i grinded the starter. sometimes the car will start roughly and immediately stall, or will stall the first few seconds as i am backing out the drive way. dealer about this they told me i was using cheap gas and to use a better brand, but i always use brand gas, i even use fuel injector cleaner dealer later told me i needed to have the fuel injection flushed with their system for $199, plus tax and charges, hearing it was not good for the vehicle, i declined. i have also noticed a clunking/bumping/banging noise when turning, especially hard turns. my brakes need to be replaced, the front brakes are starting to make a thump when braking, and yesterday when braking hard, i heard a squeal noise, (rear?). fuel gauge sometimes rapidly fluctuates, when driving, and at times when accelerating,(though not concurrent) i hear a swoosh/gargling sound. i was accelerating too hard. the fuel gauge will swing as much as a 1/4 tank when driving before recovering to the correct position. gauge shows low fuel level, low fuel light comes on, i only needed 10-12 gals to fill it (~16 gals). *tr | |||

| We purchased a 2005 chevrolet impala from a dealer on march 16, 2006. on march 21, 2006, we were traveling down a 2 lane highway at 45 mph. the traffic in front of us stopped suddenly. i applied the brakes and heard a loud pop. the brake peddle then went to the floor and i hit the van in front of me twice before i was able to turn down a side street and let the car coast to a stop. our insurance adjuster came out the next morning and took pictures. the car was sent to a body shop to be torn down. gm was notified of the problem with the brakes. the body shop was told not to touch the car until gm could send an inspector to take a look at it. the inspector finally came out and retrieved the information from the black box and took pictures of the brake linkage system. he asked if we had found any parts in the floor under the steering column after the accident. we told him no. gm then took 5 months to finish their investigation. we were not allowed to allow anyone to touch the vehicle until they were done. they came back to us and told us that they were not responsible and that the brakes had been tampered with. we were all set to go after the dealer when my husband decided to look at the brakes himself. when he did, he found the missing part the inspector had asked about. the part was visibly broken. gm has laughingly offered us $2,000.00 for this incident. my husband and i sustained more than $2,000.00 in medical bills. this is a complete joke. in addition to the brake failure, neither one of our air bags deployed even though we hit the other vehicle straight on twice. there has been no recall on this brake part or air bags. *nm | |||
