GMC Problems
Erratic Fuel Gauge Operation
The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.
On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000...
Loss of One or More HVAC Blower Motor Speeds
The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.
Rear Suspension Low Due to Failed Air Compressor
On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.
Outside Door Handles May Break
The outside door handles are prone to breaking—all doors are affected by this condition.
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 Recalls (Recent)
The Front Passenger Airbag May Not Deploy as Designed
The second stage of the dual-stage passenger airbag will not inflate in a severe frontal impact. Accordingly, the airbags do not meet the federal safety standards. In the event of a crash, an improperly deployed airbag will increase the risk of injury to the seat occupant. Dealers will replace the front passenger airbag to correct this concern. The General Motors recall number is 11302.
GMC Savana 1500, GMC Savana 2500, GMC Savana 3500Seat Belt Warning Light May Not Illuminate as Expected
Certain vehicles may have been produced with a driver's side seat belt buckle electrical connector that does not fit snugly with the connector terminals, causing the electrical connection to be intermittent. This loose electrical connection may cause the driver not to receive a visual or audible warning that the driver's seat belt is not fastened. If the seat belt is not properly fastened in the event of a crash, there is an increased risk of personal injury. Dealers will replace the seat belt buckle electrical connector terminals to correct this concern. The General Motors recall number is 11322.
GMC CanyonWindshield Wipers May Fail
Snow or ice buildup on the windshield or on the wiper restricts the movement of the wiper arm. The wiper arm may loosen and cause the wiper to become inoperative. If this occurs, driver visibility could be reduced, increasing the risk of a crash. Dealers will tighten the wiper arm nuts to correct this concern. The General Motors recall number is 12036.
GMC AcadiaSteering Gear Pitman Arm Can Fail
The steering gear pitman shaft may not have been adequately hardened and could break. If this occurs, a loss of steering ability will result, increasing the risk of a crash. Dealers will inspect the steering gear and replace the steering gear pitman shaft if necessary to correct this concern. The General Motors recall number is 12005.
GMC Savana 1500, GMC Savana 2500, GMC Savana 3500, GMC Yukon XL 1500, GMC Yukon XL 2500The Low Tire Pressure Warning Light May Not Illuminate as Expected
The tire pressure monitoring system is designed to illuminate the tire pressure warning light when the tire pressure in any one tire is 25% below the recommended cold tire pressure. On these vehicles, the light will not illuminate until the tire pressure is more than 25% below the recommend cold tire pressure. Underinflated tires can result in the tire overheating, which could lead to a blowout and a possible crash. Underinflated tires also affect tire wear, vehicle handling, and fuel economy. Dealers will update the Body Control Module software to correct this concern. The General Motors recall number is 11261.

GMC Owners' Stories
Hello my truck runs great but the A/C / Heat control only works on HIGH!! I think I'm going to change out the control unit . How does that sound??? THANKS!! Oh also the turn signals ,when activated left/ right set the hazards off?!?! Spooky
My AC is working but does not blow out of the dash vents-just the floor and defrost vents. I suspect a vacumn hose problem. Does anyone have advice? vpsonofvp@yahoo.com
I have the same problem, that was addressed some years ago, Without an answer that Question is "I have gas going into my exhaust pipe, I have changed spark plugs and wires, Fuel injector, coil pack, pressure tested cylinder number 4, It still has gas going into the exhaust pipe,on cylinder number 4, Someone told me it may be my fuel regulator any other suggestions , I WANT TO HEAR THEM,HAS ANYONE ELSE HAD THIS PROBLEM ON A 2000 GMC Sonoma 2.2 liter motor??
i currently have my 2003 gmc sierra 2500 in the repair shop at a local gm dealer. it has been there over a week and they cannot figure out what is wrong with it. The range shift inhibitor light came on the dash board so they replace the transfer case for $2100 and the light is still on and they cannot figure out why. They said the gears were wore out in the 4 wheel drive but i find that hard to believe as it only has 83000 miles and i never used it for heavy duty 4wheel driving just occasional driving on snow roads and driveways nothing major. If you can figure out what is wrong would greatly appreciate any ideas as the dealer cannot seem to figure it out. I would like my truck back without a larger bill already bad enough. thanks for any help
I have a 2006 envoy so far the fuel level sensor had to be replaced (32800 miles) cost me 527.00$ GMC dealer. 4000 miles later it failed again, replaced n/c. ( now they offer me half the cost ) Air cond. leaks (can't find). Rear hatch struts leaking, front struts leaking. The car has 41000 miles and I do not abuse it, always owned a chevy or GMC vehicle, going sell it before any thing else fails. WILL NOT BUY GMC AGAIN. They treat their loyal customers badly.
