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 brake pedal. My brakes 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!!!

Driving a rented Chevy Impala with 7,000 miles on the odometer in reno, nv, I was on a moderate downward slope at 65 miles an hour when I used the brakes to slow the car. There was an immediate shaking in the front end and steering wheel, enough to believe that I had a flat in a front tire, or had some other substantial mechanical problem. Releasing the brakes, the shaking stopped. This shaking occurred several more times on the hill as I slowed the car. I immediately returned the car to the rental company and reported the problem. I was told that this commonly occurs with Impala and was due to the poor brakes installed on the car. The shaking was severe enough to, in my opinion, cause drivers to lose control of the car in a situation where they were required to brake and maneuver simultaneously. I won't be renting any more Impala.

Brakes began pulsating rapidly while going down steep decline. This resulted in extreme difficulty to control car. Car was taken to dealership and rotors were turned down. The car began doing the same thing 2 months later. Dealership said there was nothing they could do and handed me papers stating to just gear car down when driving down mountains. Unfortunately, this doesn't correct the problem.

We were driving through the mountains in our 2009 Chevy Impala when we came upon a steep grade. I applied the brakes to prevent from accelerating too fast downhill. About halfway down the front end of vehicle violently shook as I applied the brakes. The longer I applied them, the worse the vibration. If I were in an emergency braking situation, I know that my stopping distance would be severely affected. Luckily, I wasn't put in that situation this time, but next time I might not be that fortunate. This problem is nothing new for Chevy - I had the exact same problem with a 1995 Chevy cavalier I owned some years ago. It appears Chevy has done nothing to fix the problem on its vehicles. Why did my tax dollars go to this car company"!"

Lose control of vehicle on wet roads. Brake rotors needed replacement at 12,000, 22,000 & 33,000 miles. Tires also replaced 3 times because of excessive wear on inside of back tires. Car out of alignment causing rearend to "push" car in wet weather. Dealer can't get car aligned properly. Vehicle sits at dealer because it is unsafe for my family to drive dealer cut rotors 1st time replaced 2nd and cut 3rd time. Each time they replaced the brake pads. At 12,000 dealer replaced tires after complaints that vehicle almost killed our entire family going 35 mph on interstate 80 in rain. GM recalled police Impala for same issue but refuse to recall consumer Impala please help before more innocent people are killed.
