  • 66,000 miles


The contact owns a 2007 Chevrolet Impala. The contact stated that the all four tires were worn down to the metal after a short period of time. The tires were replaced. The vehicle was taken to an authorized dealer who stated that they were unaware of the problem. A local mechanic stated that the wheels were the cause of the tire wear. The contact called the manufacturer who stated that they would look into the problem. Additionally, there was corrosion on the emissions solenoid which she was alerted to when the check engine light illuminated. The vehicle was taken to the dealer who stated that either carbon was stuck in the valve or the solenoid was full of water. The vehicle was repaired. Also, the cable to the battery was corroded. Two mechanics inspected the vehicle and stated that the failure was not caused by normal wear and tear. The vehicle was repaired. The current mileage was approximately 73,000. The failure mileage was approximately 66,000.

We bought our 2007 Chevrolet Impala 3lt new in February 2007. The car just turned over 50,000 miles. At 38,000, we noticed the passenger seat heating element quit working. Chevy dealer estimates the cost of repairs at about $200. At 48,000 the shifter release switch stopped working, so the shifter could not be moved from the park position. Chevy dealer said a wire broke in the center console and repairs were $137. From about 45,000 miles to present, the transmission occasionally slips when accelerating from a stop at an intersection. The engine revs for about a second or two before the transmission engages. The Chevy dealer has had the car in twice for this problem, the second time for more than a week, and we're told it doesn't happen in the shop. The slip happens about once every two days that we notice. Now, at 50,100 miles, the exhaust has gotten louder and a repair shop said there's a crack on the top of the left muffler. The Chevy dealer says it's not in warranty, and the job will cost $1,152. An independent repair shop says the muffler can be replaced for $160.
