Two problems related to ignition have been reported for the 2005 Chevrolet Suburban. The most recently reported issues are listed below.
A/c system would randomly blow hot air; then fan would run with ignition off; then fan speeds would quit working; finally blower quit altogether. Gm has 2 service bulletins out with exact problem description, but they claim my vehicle not covered.
My daughter was driving down the road and speedometer began acting erratically. At a stop light speedometer reads 25 mph. Ignition was turned on/off with no results.
