They put a new clutch on my truck. The service engine light came on after I picked my truck back. I took the truck back 2 times to find out what was causing the light to come on. Both times I was told it was nothing. I finally had the Chevy dealer check the truck. The Knock sensor wiring harness was pinched between the transmission bell housing and the engine block. Kirkwood tire refused to compensate me for the damage they did to my vehicle while it was in their care. The manager also was very rude and used a loud hostile voice when I stopped by to discuss the issue with him. DO NOT TRUST THEM WITH YOUR VEHICLE!!!!
