Two problems related to instrument panel failure have been reported for the 2005 Chevrolet Silverado. The most recently reported issues are listed below.
The speedometer one morning just went to 110 mph when I was driving 55 and then stayed. It would work one minute and then not the next. Finally after two days it stayed at 160. There was no way to drive it and tell what speed I was going. I have received a speeding ticket recently and wonder if the speedometer was malfunctioning then. The failure speedometer was 63,000 just 2,000 out of warranty. I went to the dealer who showed me the special bulletin on the 03 and 04 but since mine was an 05 I had to pay $501. 30 to have it repaired. I placed an incident w/ gm who had the guts to tell me that there was not an instrument panel failure on the 05 (kinda funny since I have a 05 that failed) and that since my vehicle was not an 03 or 04 that it couldn't be happening. Even though the dealership that fixed it knew right away the problem and admitted I wasn't the first 05 he had seen. The entire instrument cluster was replaced.
The contact owns a 2005 Chevrolet Silverado. The contact stated that the vehicle failed to start accompanied by the illumination of the check engine warning light. The failure was recurring and sporadic. Additionally, the instrument panel failed and the head lights would sporadically fail. The contact also stated that the rotors needed to be replaced on a regular basis. The vehicle was taken to an authorized dealer, who was not able to diagnose the multiple failures.
