GMC Sierra 1500 HD Problems

Speedometer or Other Instrument Panel Gauge May Work Erratically

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.

Instrument Panel Lights Flickering and Exterior Lights Intermittent

The headlight switch used on the GMC Sierra 1500 HD is known to fail through normal operation. Since the headlight switch is also integrated into the interior lights, a malfunctioning switch can cause issues with interior lights as well.

  • Symptoms of a failed headlight switch include:
  • Headlights and taillights failing to turn on or off
  • Interior lights flicker, or fail to turn on or off
  • Gauge cluster lighting off or flickering with headlights on
  • Parking light malfunctions  

This issue is well known with General Motors Trucks and SUVs, and is solved by testing and, if needed, replacing the headlight/dimmer switch. Bad grounding wires at the tail-lights, and dirty/corroded tow package wires can also lead to some of these issues. 

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

GMC Sierra 1500 HD Recalls

Passenger Frontal Air Bag Inflator Ruptures On Deployment

The passenger frontal air bag inflator may rupture on deployment, causing metal fragments to come through the air bag and injure occupants. Dealers will replace the passenger frontal air bag inflator free of charge to resolve the concern.

Possible Under Hood Electrical Fire

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

Possible Under Hood Electrical Fire

The wiring to the washer system heater may overheat due to a failure in the heater module. This could cause other electrical features to malfunction, smoke to develop, and an electrical fire could result. Dealers will install a wire harness with an inline fuse to protect the washer heater module. This recall is expected to begin on September 12, 2008. The General Motors recall number is 08048.

GMC Sierra 1500 HD Reviews

Pretty nice truck to drive. Great for mountain trips and towing. Cons: had a few things break down, fuel pump x2, water pump, alternator, transfer case replacement. Overall I like the truck, but it's not real practical due to gas mileage.
