Most reported GMC Yukon problems
A clicking noise may be noted from the turn signal flasher after the turn signals are switched off. This is commonly cause by a faulty turn signal switch which will require replacement.
One or more fuel injectors may become stuck closed causing an engine misfire and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.
The steering may develop a clunk type noise from the upper intermediate steering shaft. Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.
Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.
The steering wheel position sensor may fail, resulting in the service stability message being displayed.
The rear window defogger may stop working due to a wire terminal broken off of the rear glass. Our technicians tell us that terminal can be reattached using a special glue or silver solder.
The air conditioning compressor may develop an abnormal noise and require replacement. We recommend that whenever an AC compressor is being replaced for a noise condition, a filter kit should be installed to prevent any metal particles in the system from damaging the new compressor.
The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.
Units with 4 wheel disk brakes may develop at situation where the park brake does not hold as it should. Our technicians tell us this can be caused by worn park brake shoes located inside the drum section of the rear brake disks. The worn shoes should be replaced and properly adjusted to correct this issue.
The CD player may fail due to an internal fault with the radio. Our technicians tell us that in most cases, the radio unit will need to be sent to a specialty repair shop to correct this issue.
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
