I purchased the 2006 Impala in 11/2006 when stopping the steering and front end shakes and vibrates. 1st the keyless remotes stop working which included my automatic start not working that happened 12/7. I am a trooper so I waited took my car to the chevy dealer 4/08 and they said there was a recall on the system so they fixed that and my tire monitoring system(which went out again on 12/1/08). My seatbelts wont lock in you have to force it hard several times and then still comes out on both the passenger and drivers side. My rear left door stop wrkg 6/08 1st the door would not close now it does not open at all. On 12/21/08 the power steering went out while driving at 55mph on the expressway. Also the heat stop working and the rear defrost 12/16/08 and it is freezing in chicago. Took car to dealership and of course the warranty was expired so I was stuck paying the $300 bill for the power steering. My husband refused to pay the 400. 00 for them to replace the thermostat and thermostat gasket. Well two days later car is back in the shop because now 1/3/09 the water pump is leaking waiting on a callback now from the authorized mechanic with the final report on what all is wrong with this car that just came from the other authorized shop on 12/21. Mind u the car was only driven like 4 miles b4 the other problems started happening. I have had it with this car. I will send in more information when I get the final verdict on the death trap from the authorized mechanic when he calls me back today 1/3/08.
