2005 GMC Yukon XL 2500 ProblemsInstrument Panel Lights Flickering and Exterior Lights Intermittent
The headlight switch used on the GMC Yukon XL 2500 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.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
2005 GMC Yukon XL 2500 RecallsFuel May Leak from Fuel Rail
The retainer clip for the fuel rail pulse damper may fracture and allow the damper to come loose from the fuel rail. A fuel leak in the presence of an ignition source may result in a fire. Dealers will replace the engine fuel rail pulse damper free of charge. The recall began August 31, 2006. The GM recall number is 06080.
On vehicles equipped with the Bosch hydraulic brake booster, the boost pressure accumulator may crack and break away from the hydro-boost assembly during normal operation. If this were to happen while the hood is open, fragments from the accumulator could injure people standing in the immediate area. The loss of fluid while driving would cause increased steering and braking effort and a crash could occur without warning. Dealers will test the hydro-boost assembly for function of the two-function valve. If the hydro-boost assembly fails the test, it will be replaced free of charge. The recall began March 23, 2005. The GM recall number is 05006.
707 vehicles may have a missing brake pedal push rod retainer. If the retainer is missing, the brake pedal could disengage from the booster push rod. This could result in loss of braking ability, increasing the risk of a crash. Dealers will inspect the affected vehicles and install a push rod retainer if necessary. General Motors will begin contacting owners by telephone on March 10, 2005. The General Motors recall number is 05039.
