| Cost over $483. to have dealer replace brakes on this vehicle. they also said they were replacing rear rotors in the deal. when car was returned we noticed that while going downhill, applying the brakes that the front shook violently. called service mgr at gm dealer who preformed this work, and he told me not to use brakes going downhill to maintain speed, but to gear the car down with the use of transmission. i live in southwestern pa where there are hills everywhere. do i damage the transmission using this process suggested by the gm service mgr, or use brakes? thought that was why cars had brakes on them anyhow?? | |||

| This vehicle is very difficult to maintain control when applying the brakes due to the warping of the rotors. after reasearching information on the rotors to a 2009 chevy impala lt, i see that there are many complaints about constantly replacing them on this vehicle. at first i thought it was my brakes, but after paying that over-the-head price at the dealership to inspect further, my suspicion led me to believe that it could have something to do with my rotors; the findings were that it was indeed my rotors and not just 1, but all four. something has to be done about this because no one should have to constantly replace rotors, due to some poor engineering on certain components. i almost got into 3+ accidents trying to apply my brakes when drivers decided that they were going to engage in poor, life-threatening judgements. applying the brakes to these easily warped rotors, even when coming down from a speed of 50, causes the pedal, steering, and entire car to shake as if there was an earthquake or you are basically like fred flinstone and using your feet on the roadway as oppose to your engine. | |||

| The vehicle traction control system (tcs) - service system warning message appeared ( lit up ) on dash display as the vehicle operator attempted to pull out into traffic, making a left turn onto the roadway.the warning message was accompanied by a grinding noise in area of the left front wheel and a sudden decrease in engine power and self slowing/braking of the vehicle suddenly, causing other vehicle operators on the roadway to take evasive action to prevent a collision. the owner contacted several dealers about this problem as the service traction controll warning activated three times previously but without power loss on those occasions. the vehicle owner was advised by all the dealers that they can only diagnose the problem when the warning light is lit as it is a random problem. this is a life threatening defect that is widely known by impala owners and chevrolet dealers for the past seven or eight years and nothing has been done to effect a safety recall. google { impala traction control problem and you will see many,many complaints about this defect. | |||

| With brake application the vehicle vibrates, shudders, and the steering wheel becomes hard to hold. condition is most evident on down hill braking. after brakes cool the problem is less noticeable. the problem can then happen at any given brake application, without warning. the vehicle is hard to control in this condition and the driver and occupants are startled by the vibrations taking away the drivers focus on driving. | |||

| I noticed some time back that when applying the brakes that i would get a rough vibration, such as with bad rotors. i took the car to the dealer that i purchased it at and they looked it over and stated that everything was fine. since then everytime i hit the brakes the vibrations have only gotten worse, it's to the point now that it violently shakes the entire car and feels as if it's going to jerk the steering wheel right out of my hands. so i made another appointment for this issue and a new one; sometimes my dash lights will flicker and it will tell me it's 102 outside when it's only 70 and automatic tire pressure sensor is way, way off. i have also noticed recently that my front tires have become excessively worn on the outer edges to where there is only tread in the center and this shouldn't be a problem with only 21,500 miles on the vehicle; i should have been able to get about twice that out of the factory tires. at my last appointment they have still said there is no notable problems with my impala. | |||

| We live near mountain drives. on steep descents the brakes warp and chatter to the point that the car shakes violently and is difficult to hold steady. the last trip the shaking was so violent that a cup was thrown from the cup holder in the front of the car. this has happened three times and three times the dealer has not been able to correct the problem. it is extremely dangerous and we no longer take our car into the nearby mountains. we have a car we cannot drive safely in our area. | |||

| While applying my brakes the front end shakes and sterring wheel shakes so badly, it makes you want to not use the brakes and pull your foot off the brake pedal. the brakes appear to have hard spots in the rotor. there are 35,900 miles on this car which we purchased brand new in july 2009. my wife drives this car and she says it has vibrated since 13,000 miles, but has recently been a more almost violent vibration when coming to a stop. this happens when coming off an expressway ramp after driving maybe 20-40 miles and not even using the brakes prior to having to apply on the exit on a gradual slowdown, not a sudden stop. this causes one not to want to drive this car. i was a master tech on trucks for 20 years, and just driving this one time, i knew the probable cause, i was not just guessing. i checked the web and was astounded to see the car manufacturer i had always aligned myself to, in the complaint section responding negatively to customers. i called 2 local dealers today to try and get the car in to be repaired and asked both service reps if it would be covered under warranty, and they both in the cincinnati area said no, it was a wear problem. waiting to hear a response from this complaint. | |||

| In june 2010 i was driving on the interstate 90 west toward denver co. the terrain was steep and winding and due to heavy traffic the pace was fast. the traffic ahead of me began slowing and i began to slow by steady light pressure on the break pedal. my breaks heated up fast and i found myself without breaks for a short period of time due to the rotors feeling as though they were warped and the front end started vibrating. i down shifted to 3rd. gear but that was not enough to slow me enough so i downshifted to 2nd and this still was not enough to maintain a downhill speed to keep from having to use the brakes. finally i shifted to !st gear to maintain the safe speed that i needed. the problem seems to be that the car freewheels so excellent that even on lower grades as experienced in the carolinas in october when we were there the car is almost impossible to gear down so as not to overheat the brakes when trying to maintain posted speeds in mountainous country. i discussed this with solomon chevrolet in dothan where i get the car serviced and the dealer from whom i purchased the car. they had no suggestions but assured me there was nothing they could do dealership wise to help me. i feel it is a very dangerous situation which does not surface unless you drive in the mountains. | |||

| Driving down a steep hill heading from the california coast back to arizona, upon braking car started shuttering and shaking badly almost causing me to lose control. later found out after searching this site and many others that there appears to be a warped rotar problem. after all the complaints on this one item that i have seen online, why is this company not being put to the fire to fix this. my car is now out of warranty so i am going to have to pay out of pocket close to 1k for a fix that might last 20,000 miles? i wonder how many people have lost control or worse their lives because of their new chevy and didn't even know about this. oh, by the way your welcome for the money. at least toyota is fixing their problems!!! | |||
