2009 Chevrolet Traverse electrical system problems

Tl* the contact owned a 2009 chevrolet traverse. The contact stated that various warning indicators illuminated. In addition, the warning indicators for the air bags, service engine, and low beam headlights shorted several times. The contact smelled a burning odor near the front of the vehicle several times. The vehicle was repaired several times by the dealer, but the failure recurred. While driving at an unknown speed, a deer crossed the vehicle's path and crashed into the front of the vehicle.

My 09' traverse started to shudder intermittently on acceleration and then the service engine light (sel) came on. I had the car diagnosed and the code was a p0302 (misfire cyl). I had the car serviced and repaired by an ase certified mechanic. All coils and spark plugs were replaced along with fuel inj service, performance restore (oil, gaskets, etc). No discrepancies were noted with previous coils/plugs. The car appeared to be fixed. No problems were noted during an 800 mile roundtrip.
