Two problems related to instrument panel failure have been reported for the 2005 Chevrolet Suburban. The most recently reported issues are listed below.
On August 3rd, 2012 my 2005 Chevrolet Suburban 1500 first showed signs of the instrument panel cluster failing. The tachometer showed a reading of 5,000 rpms with the engine idling. This continued for a few days and then seemed to go back to normal. About a week later the speedometer began to indicate incorrect readings. By September 6th, 2012 I had noticed it would sometimes show a speed of 120 mph while going an actual speed 50 mph or sometimes show 29 mph while going 50 mph. For a while it was moving the needle below 0mph. I can no longer rely on the gauges of this vehicle with only 65,000 miles on it.
Instrument panel failure. Speedometer stuck below 0 (zero). Tire pressure readings keep changing in minutes ranging 20-46. Schedule for replacement of the instrument panel cluster and will cost $450-600.
