2006 Chevrolet HHR 4dr Wagon

172-horsepower 2.4L I4 5-speed manual FWD

22000 mi   Again addressed occasional dead/no start problem. Corporate involved. Level of attentiveness much improved. Replaced ignition switch. They're not sure this is the fix, but it was best guess. Month has passed, but problem only once every 3 mos on average. 
24500   10/2-10/6 Dealer again tried to repair intermittent problems. Replaced BCM computer. Result was no fix, but new problems. Took car again from 10/9-10/15. Reprogrammed and replaced other module. Results to be determined over period of time. 
26000   Same problems recurred, so October repair also was a failure, and new problem created - mileage down 20%. GM involved again cuz nobody knows what to try. All my dealer contacts fired-again, so starting again with new person. I am pushing for new car. 
27000   New service manager and general manager neither has any idea what to do, so we are negotiating an arbitration for a replacement vehicle. 
28000   Dealer took one last shot at fixing recurring "no-start" problem, but found nothing. Reached agreement to get me into new vehicle. Transaction is complete and I will add vehicle here.
