2024 GMC Yukon Problems

What owners report

Owners of the 2024 GMC Yukon most often report sudden loss of engine power, often at highway speed with no warning, on vehicles with the 6.2L V8; many complaints describe the engine being replaced after internal damage, and some involve vehicles that had already been inspected under a related recall. Other recurring reports involve the automatic emergency braking system engaging when nothing is in the way, transmission and drivability symptoms such as stalling or harsh shifting, and intermittent electrical and software faults.

   Sudden engine shutdown / stalled engine

   • 83 complaints (78%)
   • median 21,116 mi at 1.8 yrs old (11 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2024–2026

   Complaints describe the engine quitting without warning, frequently at highway speed, with the vehicle going into neutral and losing power assist for steering and brakes. Some say it restarted after a pause and then failed again, while others were told the engine was damaged internally and needed replacement. Several owners say the vehicle had already been checked under a recall remedy and passed before the failure occurred, and some mention long waits for replacement engines. Reported from a few thousand miles up into the 30,000-60,000 mile range, often at highway speeds.

   NHTSA complaint #11711801, filed 2026-01

   “Was driving on the interstate when the engine stopped running. My screens went off and came on saying to press the start button to turn on as my car is still moving. Once pulled over couldn’t get the car to turn off or shift out of park. Engine never started since then. Mechanics looking at the Yukon have verified that my engine did seize up. My car is less than a year old.”

   Engine noise, oil loss and check-engine light after recall

   Mentioned in 8 of 60 sampled complaints

   Owners describe knocking or rattling from the engine compartment, oil consumption or leaks after service visits, and a check-engine light that comes on or flashes intermittently. Some complaints mention that an oil change to a heavier grade oil and an engine inspection were performed, and that symptoms continued afterward. Others report the dealer replacing a filter or gasket and the concern returning. Mostly reported between roughly 10,000 and 45,000 miles, often shortly after a recall inspection or oil change.

   What to check: Check the oil level and look for a fuel or burnt smell on the dipstick, and ask what oil grade and filter were used at the last service. Have any stored codes read before purchase.

   “The SUV has 46,000 miles on it. Recently, the check engine light illuminated, prompting me to take it to the dealership for servicing. The diagnostic codes retrieved were U0285 and U1345. I was informed that the aero shutter required replacement. There was no physical damage; it merely ceased functioning. The dealership confirmed the active check engine light and conducted a diagnosis. …”

   • 2 mention a crash, fire or injury
   • filed 2024–2026

   Complaints describe intermittent total audio loss including chimes and warning tones, infotainment screens going blank or freezing, and occasions where the vehicle appears dead and then starts after several minutes. Some owners report water entering near the rear wiring harness with a mildew odor, and repeated dealer visits that did not resolve the concern. Reported from roughly 15,000 miles upward, often intermittent and hard to reproduce at the dealer.

   5 related service bulletins

   What to check: Test every audio source, warning chime and screen function, and check the cargo area and rear wiring for dampness or odor. Ask whether any modules or harnesses have been replaced.

   “I constantly get the frontal crash not available warning the navigation picks up on conversations stereo freezes navigation screen has been blank no map data visible screen will not change from daylight to nightime anymore (I have taken the vehicle twice to the dealership and have it repaired then it happens again) when driving the vehicle will randomly brake and says something is near when there is nothing close”

   NHTSA complaint #11643353, filed 2025-02

   “Vehicle shut-off while driving on the expressway, around 70-75mph. Upon vehicle turning off, I had no option but to coast off to the left side, which thankfully, freed me from traffic for the most part. If anyone who have been a foot over, they would've hit me. I have had numerous electrical issues with this vehicle and have taken it to the dealership but they have been unable to duplicate the issue. Vehicle was immediately taken to the dealership (and they still have as of this incident report submission). …”

   Transmission and drivetrain

   Stalling, harsh shifting and loss of drive

   • 13 complaints (12%)
   • median 17,500 mi at 2.0 yrs old (2 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2025–2026

   Owners report the vehicle stalling at stops or while accelerating, messages about gear selection not being available, and the transmission shifting into neutral on its own. Some describe harsh shifts, shudder or delayed throttle response, and dealers either could not duplicate the concern or pointed to a software or cooler line issue. A service bulletin describes checking transmission cooler lines for a twist when these symptoms are reported. Mostly reported between roughly 10,000 and 25,000 miles.

   3 related service bulletins

   What to check: Ask whether the transmission cooler lines were inspected and whether any transmission software updates were applied; pay attention to shift quality and hesitation when accelerating from a stop.

   “This report documents two separate safety incidents involving the same vehicle that occurred on different dates. Approximately one month prior to the most recent incident, while driving my young children to school, the vehicle experienced a sudden and severe loss of braking effectiveness while in motion. I was unable to stop normally at stop signs and had to roll through and roll to a stop. …”

   “I had just backed the truck out of a parking space (while turning) and shifted the transmission into 'Drive' with my foot pressing the brake pedal (not the gas pedal). When I took my foot off the brake pedal in order to transfer it to the gas pedal the vehicle suddenly accelerated forward without my foot ever pressing the gas pedal. The vehicle traveled forward about 20 feet before I was able to stop it by pressing the brake pedal. …”

   Forward collision avoidance

   Automatic emergency braking activates with nothing ahead

   • 10 complaints (9%)
   • typically at 1.9 yrs old
   • 1 mention a crash, fire or injury
   • filed 2024–2026

   Complaints describe the vehicle braking hard on its own when no obstacle is present, including at highway speed, and adaptive cruise control slowing or stopping unexpectedly. Some owners report the system disengaging with a warning message on the dash, and that dealer visits did not reproduce or resolve it. A service bulletin asks dealers to use a customer concern verification sheet when taking these reports. Reported across a wide mileage range, including under 20,000 miles, in clear weather and on open roads.

   1 related service bulletin

   What to check: During a test drive, note whether the forward collision warning or automatic braking triggers without cause, and ask whether any related software updates or sensor repairs have been done.

   “1 Adaptive cruise stopped me several times for no reason as there was nothing on the interstate and the weather was clear. This was very jarring at 80 miles per hour on the interstate created a hazardous and dangerous driving condition as cars were all around, almost was rear-ended. 1a Adaptive cruise started all the sudden when I was stopped at an intersection almost caused a wreck, as soon as I took my foot off the break it speed up, but I was able to veer off and break several more times. …”

   NHTSA complaint #11613262, filed 2024-09

   “As I was driving the automatic emergency brakes went off and stopped me so hard and fast that I feel like I got whiplash. The seatbelt yanked me backwards, smacking my head against the headrest, I have an instant headache from it and my neck and shoulder still hurt 20 minutes later. It scared me and my child half to death, my heart was pounding and I could have been rear ended. I was driving about 40mph and was in no way in any harm/needing to break (specially this hard) for anything when this happened. …”

Buying note. Ask for documentation of the 25V274000 engine recall inspection and any subsequent engine work, since many complaints center on the 6.2L V8 losing power. A pre-purchase inspection that includes reading stored codes and checking oil condition is worthwhile on this model year.
