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 temporary 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<<<

The manufacturer advised the contact that the failure potentially was contributed to the fact that he resided in a salt belt state.

I was sold a vehicle from a car dealership that supposedly had a 100+ point inspection including safety equipment. After taking the vehicle to my mechanic, I found that the rear brakes had only 10% brake pad left and the power steering was compromised.

The contact owns a 2005 Chevrolet Impala. When the contact depressed the brake pedal, the contact heard a loud grinding noise. Within a year, the failure progressively worsened. The tires were rotated and the contact noticed that the brake rotors had excessive corrosion and rust. The dealer stated that because the vehicle exceeded the warranty, he would have to assume financial responsibility for the repair. He has not had the rotors replaced. The failure mileage was 30,000 and current mileage was 54,000.
