2004 GMC Sierra 2500 Problems

Heating & Air Conditioning -- Verified

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.

Electrical & Lights -- Verified

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.

Drive Train -- Verified

The 4WD transfer case position sensor or the selector switch may fail causing the service 4WD message to be displayed.

A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

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

Body, Interior & Misc., July 21, 2005

RepairPal Expert Overview:

The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.

Brakes, June 18, 2004

RepairPal Expert Overview:

The hydro-boost housing relief valve bore may be out of specification. The seal may fracture as a result, which may reduce braking assist and slightly increase the steering effort while braking. Under certain conditions, more braking effort will be required to stop the vehicle. Dealers will replace the hydro-boost relief valve. The recall began June 18, 2004. The GM recall number is 04004.

Brakes, March 23, 2005

RepairPal Expert Overview:

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.

2004 GMC Sierra 2500 Reviews

bought my GMC 2500 in 2004 new, has 135,000 miles on it, when making turns there is a knocking noise in the steering shaft nobody has ever been able to fix it, interior on drive side had to be replaced, ac blow hot air , have to cut truck off
and restart to get cool air, sometimes it works sometimes it does't, there is a noise that sound like the drive shaft is hitting something, replaced front hubs at 100,000 miles, coatings on rims are peeling off,
sticker price 45,000
can't wait to buy another one and pay 800.00 dollars a month

My sierra was a terrific truck until it spontaniously caught fire while the truck was off and parked in my drivway. If your blower motor stops or electrical things start becoming irratic gages...ect. Keep your truck out of your garage and get it checked. a.s.a.p.

Great truck over all, however mine's AC just stopped working out of the blue one day and even though all the fuses and relays are good the unit is still not getting any power

brakes fail, company dont care, and dealers 2 different ones cant find problem or are just to lazy to give a shit
