Owners have filed 186 complaints
about the 2004 GMC Yukon with NHTSA between 2004 and 2025.
The largest single group is the electrical system.
Across this model's run it ranks 17 of 34 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 49
Against the median year of the GMC Yukon. 50 means typical for this
model; 100 means roughly double.
Severity — 42
8.1% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 34
20% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.
Odometer readings owners gave when they filed. About half of all
complaints include one.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2004 GMC Yukon
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 2011074190,310 units in Canada
Heater And Defroster
On certain vehicles, the interface between the electrical terminals of the Heating, Ventilation, and Air Conditioning (HVAC) blower relay resistor module and the wiring connector (which powers the module) may be incapable of conducting higher current levels for sustained periods of operation. In addition, moisture and other contaminants (such as road de-icing materials) may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals. These conditions may cause the relay resistor module or wiring connector to overheat, causing various symptoms such as: the HVAC blower may not function on certain or all blower speed settings; a burning-plastic smell or smoke may be present in the vehicle, or; the HVAC blower may run continually with the ignition in the OFF position. These warning signs could, in certain instances, be leading indicators of an impending vehicle fire, which could result in property damage and/or personal injury. Correction: Owners will be provided with additional warranty coverage for the blower motor resistor module/wiring connector overheating condition. Under this "special warranty coverage", should this condition occur within 10 years or 240,000 km from first vehicle registration, dealers will install a replacement blower motor resistor and resistor module connector.
Recall 200511973,473 units in Canada
Seats And Restraints
On certain vehicles, the 2nd row centre occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants. A lap portion of the seat belt routing that is not low and snug on the hips can allow unfavourable occupant kinetics in the event of a crash. Moreover, the higher routing allows the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal and internal organ injury. Correction: Dealers will modify the guide loop.
Recall 20040374,075 units in Canada
Brakes
On certain vehicles, the relief valve o-ring seal within the brake hydro-boost module could fail. If this happens during braking applications, the driver may be able to hear an engine compartment noise similar to the sound that occurs when the steering wheel is turned to a full stop position. The driver could also experience a slight increase in steering efforts while braking and parking. Under certain driving conditions, a slight increase in the applied brake pedal effort may be required to achieve the same vehicle deceleration rate as prior to the seal failure. Correction: Dealers will inspect the hydro-boost module, and replace it, if necessary.

Odometer Fraud. The contact purchased a 2004 GMC Yukon. The contact stated that while attempting to trade the vehicle in, the dealer discovered that there was a mileage discrepancy, per the Carfax report. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 165,563. The actual mileage could not be determined because the Carfax report displayed that the mileage had drastically fluctuated over the years. No other agency was contacted.

The contact owns a 2004 GMC Yukon. The contact stated while driving 45 MPH, the vehicle started losing motive power. The check engine warning light and another unknown warning light were illuminated, and a message was displayed that the gas port was reducing power. On a separate occasion, the vehicle started to lose motive power and then the vehicle started to shake. The vehicle was losing power and shaking until the vehicle was turned off. The vehicle was restarted and drove normally for six months without failure. The vehicle was taken to an independent mechanic where it was diagnosed with throttle body failure; however, the failure persisted. The vehicle was repaired but the failure persisted three more times with different diagnoses. The vehicle was taken to other independent mechanics however, the cause for the failure was not yet determined. The vehicle was not repaired for the most recent failure. The dealer was not made aware of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 123,000.

My kids and I was on the interstate and all of sudden my yukon reduce engine power.Dropping to 30 in a speed zone of 70.I was very afraid for our safety and appreciate there concerns for reducing engine power to save the truck,but that's very dangerous. So I paid to replace the throttle body and gas pedal cause that was the codes for the problem. But it's still doing the same thing and I don't have money to keep buying parts.Plus it a gm problem and I really need some help with the fixture..

WHILE TRAVELING AT HIGHWAY SPEED AND ROUNDING A BLIND CURVE THE TRAFFIC AHEAD HAD STOPPED DUE TO A CRASH. I HAD TO BRAKE HARDER THAN NORMAL AND THE BRAKE PEDAL JUST KEPT DEPRESSING FURTHER AND FURTHER UNTIL IT WAS ALL THE WAY TO THE FLOOR. I WASN'T STOPPING NEAR FAST ENOUGH AND HAD TO VEER TO THE LEFT INTO THE MEDIAN TO AVOID MAKING CONTACT WITH ANYONE ELSE. IT WAS RAINING AND AS I LOOKED UNDER MY TRUCK TO LOOK FOR WHY MY BRAKES WERE INEFFECTIVE BUT COULDN'T SEE ANYTHING AT THAT TIME. I CHOSE TO TRY TO DRIVE HOME NOT SURE WHY I HAD THE PROBLEM STOPPING. THE NEXT DAY WAS DRY AND I HAD MY BROTHER PUMP THE BRAKES WHILE I LOOK UNDERNEATH AND FOUND NUMEROUS PLACES WHERE THE BRAKE LINES WERE RUSTING AT AN ALARMING RATE AND ONE LOCATION WHERE THE RUSTED LINE FAILED. I REPAIRED THE LEAK I HAD FOUND AND WHEN I TRIED TO BLEED THE BRAKES FROM THAT REPAIR I WOULD BEGIN AN UNENDING RUN OF LEAKS UP AND DOWN THE METAL BRAKE LINES FOR BOTH THE FRONT AND REAR. THIS YUKON HAS AROUND 260K MILES BUT THOSE BRAKE LINES SHOULDN'T BE RUSTING THROUGH LIKE THEY ARE. I HAVE HAD MORE THAN 15 TAHOES, YUKONS, YUKON XLS, SUBURBANS, AND PICKUP TRUCKS FROM GM AND NEVER HAVE I HAD SUCH A RUN OF BRAKE FAILURES AS THIS 2004 MODEL YUKON WAS NOW GOING THROUGH. GM SAYS THIS IS NORMAL MAINTENANCE BUT HOW CAN ONE EVEN SEE IF A FAILURE IS OCCURRING AS MANY OF THESE LINES ARE CONCEALED BY THE FRAME, CHASSIS, AND BODY. I HAVE SPOKEN TO OTHER OWNERS OF SIMILAR VEHICLES, BE IT PICKUPS OR TAHOE'S OR SUBURBANS OF THE 2000 TO 2006 MODEL YEARS AND NEARLY ALL HAVE COMPLAINED OF CHRONIC BODY RUST ISSUES BUT MORE IMPORTANTLY BRAKE FAILURES FROM BRAKE LINES RUSTING AND THEN BLOWING OUT WITHOUT WARNING. MANY ALSO CITED THAT OF THE LINES THAT ARE VISIBLE TO INSPECT THEY WOULD APPEAR TO BE OK BUT JUST OUT OF VIEW ONE WOULD HAVE A SUDDEN BLOW OUT WITH NO WAY TO SEE OR KNOW THERE WAS A PROBLEM SINCE THE LINES ARE CONCEALED.
