My vehicle has the 3.9 l ltz package. It uses 2 to 3 quarts of oil per oil change. I am currently working with the dealership to monitor my oil consumption every 1,000 miles. So far we have used 1/2 quart in 2,000 miles. The dealership does not seemed concerned but frankly my car should not be using any oil. Gm should do something. We have a 10 year/100,000 mile warranty. I hope gm doesn't try to squeak out of fixing this issue.

Intermediate shaft in steering shaft failed. It caused a clunking or knocking feel and sound. Chevy dealer said it was a "chronic problem" with the impala. Fixed under warranty. Otherwise it would have cost about $300.00. Also rotors in front warped prematurely. Another "known problem". Power steering unit or serpentine belt squeals. Chevy dealer said it's" normal" ?

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.

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.
