2003 GMC Yukon XL Problems

What owners report

Owners of this model year most often write about a faulty instrument cluster — speedometer needles that read high or stick while parked — and about corroded steel brake lines that let the pedal go to the floor. The speedometer complaints cluster in the 40,000-80,000 mile range, while the brake-line reports mostly come in past 90,000 miles and often on vehicles driven in road-salt states. Smaller groups describe steering-shaft noises, tire wear and blowouts, and occasional stalls or reduced-power events.

1. 1
   Electrical system

   Speedometer reads high or sticks (instrument cluster)

   • 32 complaints (31%)
   • median 73,760 mi at 4.8 yrs old (26 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2003–2016

   Owners describe the speedometer needle jumping to 60-120 mph while the vehicle is stopped or moving slowly, sometimes dropping to zero, and often not resetting after restart. In several cases the whole gauge cluster or the odometer was affected, and the oil pressure and fuel gauges also read wrong. Dealers typically diagnosed the instrument cluster and quoted several hundred dollars to replace it; several owners said the repair was declined or only partly covered because the vehicle was past a special-coverage mileage or time limit. Mostly reported between roughly 40,000 and 85,000 miles, with some at higher mileage; a few owners mention it acting up more in cold weather.

   What to check: With the engine off and then running, watch whether the speedometer needle sits at zero and moves smoothly. Ask whether the cluster was ever replaced or reprogrammed and keep a record of the repair, since replacement clusters can need odometer programming.

   “Instrument panel inoperative recall notice for 7 years/70,000 miles, received after 71,000 miles even when problem started at 64,000 miles, all gauges go out at random and is interment. A call to general motors and an hour of time I was told nothing can be done I was out of recall notice mileage and I was out of luck and had to pay for the repair myself. *updated 12/12/07 updated 12/12/07”

   NHTSA complaint #10204818, filed 2007-10, 64,000 miles

   “Speedometer stick and jams. Reads incorrect speeds,off my as much as 100 MPH!. This I have found to be a common problem with Gmc's, and they know about it.”

   Brakes

   Rusted brake lines, pedal goes to the floor

   • 18 complaints (18%)
   • median 124,000 mi at 11.4 yrs old (16 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2011–2019

   Complaints describe the brake pedal sinking to the floor with little or no warning, usually traced to steel brake lines rusted through above the rear axle or along the frame rail, where fluid leaks out. Owners often say the visible section of line looked fine while the corroded area was hidden, and that all lines were eventually replaced. Dealers generally replaced the lines at the owner's expense; some owners also reported spongy pedal feel or intermittent ABS/alarm warnings without a line failure. Mostly reported from about 55,000 miles upward, with many past 90,000 miles; several owners mention road-salt climates.

   Recall 04V045000

   What to check: Have the steel brake lines inspected along their full length, especially above the rear axle and near the fuel tank, not just where they are easy to see. A recall (04V045000) covers an out-of-specification brake hydro-boost valve bore, which is a different part than the lines, so ask what has actually been replaced.

   “Brake line popped causing my 2003 Yukon Xl to rear end a car stopped at a light at 30 MPH glad I am not seriously injured scariest thing that ever happened in my life not being able to stop and had plenty of room. Time for a class action suit if not one already in place. This is lives people!”

   NHTSA complaint #10536619, filed 2013-08, 157,000 miles

   “Brake lines under drivers seat are completely rusted through. Vehicle is garage kept and seems to be experiencing excessive rust on brake lines. While driving vehicle brake pedal went to the floor almost causing me to have an accident. My family and I own and have owned numerous GM products and we're very disappointed with this safety hazard not being addressed by GM. Maybe it's time to shop elsewhere...”

   Steering

   Steering clunk or squeal from the intermediate shaft or

   • 7 complaints (7%)
   • median 13,838 mi at 1.9 yrs old (6 state mileage, few)
   • filed 2004–2007

   Owners describe a clunking, popping or squealing noise when turning, accelerating or going over bumps, sometimes with a vibration felt through the steering wheel. Repairs mentioned include packing or replacing the intermediate steering shaft and replacing the steering gear box; one owner reported loose intermediate-shaft bolts. Some dealers said nothing further could be done or declined the repair before another dealer replaced parts. Mostly reported at low mileage, from a few thousand miles up to about 46,000 miles.

   What to check: Turn the wheel slowly while parked and listen for clunks or squeals, then drive over a bumpy surface and feel for play through the column. Ask whether the intermediate steering shaft or gear box has been replaced.

   “At 32,652 the intermediate shaft had to be replaced. We have had lots of problems with this vehicle and have not owned it for a year! Between the monthly truck payments and repairs we could have put a nice down payment on a second house and kept the reliable truck we traded this one for!!”

   NHTSA complaint #10151751, filed 2006-03, 32,652 miles

   “While driving up a mountain intermediate steering shaft bolt became loose, and was just 3 turns from falling off. Consumer contacted the manufacturer, and they listened, but did absolutely nothing. Consumer later filed a complaint with the bbb. Vehicle was equipped with 4 ply tires which was unacceptable for this type of vehicle.”

   Engine cooling

   Stalls or sudden reduced engine power

   • 7 complaints (7%)
   • median 65,600 mi at 8.1 yrs old (6 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2004–2013

   Owners describe the engine dropping to idle with a reduced-power message while driving, sometimes after towing, and other cases of the engine quitting at speed and restarting after a short wait. Diagnoses mentioned in complaints include the throttle body and throttle actuator circuit, the ignition switch and the fuel pump; some owners report the symptom returning after repairs, and one owner was told the reduced-power behavior was normal protection and not covered. Reported from about 54,000 to 130,000 miles in the sample, with several in the 70,000-90,000 mile range.

   4 related service bulletins

   What to check: Ask whether the throttle body, ignition switch or fuel pump has been replaced and whether any stored codes were read. A service bulletin describes an intake-valve decarbonizing kit for rough idle, extended crank or misfire, so it is worth asking if that maintenance was done.

   2 excerpts from owner complaints in NHTSA records

   “Reduced engine speed warning light comes on and drops truck to an idle. I feel this is very dangerous in traffic and on highways. My mechanic has not been able to locate problem. All forums and online help has brought me to dead ends. This is my last resort, I believe GM knows what the problem is and am hoping they will do the right thing and recall before someone is seriously hurt or killed from this issue.”

   NHTSA complaint #10438674, filed 2011-12, 120,000 miles

   “This vehicle displayed a message thet the engine was running at reduced power. The vehicle's engine slowed to idle speed while we were driving on a public street. We had been pulling a travle trailer just prior to this happening. This created a possible danger to us as well as other drivers on the street since we could hardly get the vehicle to power up so we could get off the street. I called the local dealer in beaumont, tx. I was told that this was a commom operation to protect the enging from damage and that there is no recall for this problem. …”

   Tires

   Tire wear, tread separation and valve stem failures

   • 9 complaints (9%)
   • median 31,000 mi at 4.2 yrs old (6 state mileage, few)
   • filed 2004–2013

   Complaints describe uneven inside-shoulder cupping and wear, tread and belt separating from the carcass at highway speed, and valve stems failing and causing repeated flats. Owners often note that rotations and alignments were done and that dealers or tire shops offered little assistance. Reported from about 27,000 to 73,000 miles, with one early report near 35,000 miles.

   4 related service bulletins

   What to check: Check tire date codes, look for uneven inner-edge wear and cracking, and inspect the valve stems. Confirm the alignment was recently checked and ask about any tire size change, since a service bulletin notes calibration support is limited to factory-sized tires.

   “I own a 2003 Yukon Xl. Purchased 4 michelin tires from ntb in april 2007, $700.00. New tires have 18,000 miles on them. Jan 2009 valve stem failed and was replaced by ntb, no damage to tire. May 2009, second tire went flat doing 70 miles an hour with my kids driving on the highway home from college. Tire went flat, immediately pulled off to the side of the road. Tire was damaged and had to be replaced, $225.00. Cause of damage was valve stem, tr 413. One week later, third tire went flat going back to college. Immediately pulled off of highway. …”

   “The firestone wilderness tires on my Gmc yukon are failing to perform properally. Cupping and improper inside wear are a sever problem. The tires have been maintain and rotated for 35,000 miles. Alainment has been checked by 2 different sources 1 being the GM dealer. Tire ware is a very serious saftey matterwhich could cause serious injury.”

Buying note. Check the speedometer and other gauges carefully and have the brake lines inspected end to end before purchase, since both are the most frequently reported problems and the brake lines can be severely rusted in areas that are hard to see. Service records showing cluster work, brake-line replacement and steering-shaft repairs are useful evidence that the known issues were addressed.
