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.
