2023 GMC Yukon owner complaints (15)

• UNKNOWN OR OTHER

  I was driving over the Cooper River Bridge and a loud explosion occured, almost like a loud gun shot. The entire first window of my sunroof exploded. Nothing hit it, no cars were around and it was around 9pm at night

• POWER TRAIN,ELECTRICAL SYSTEM,ENGINE

  I have a 2023 GMC Yukon that has been to the dealership 3 times in a weeks time, and as of today, 8/31/26 will be the fouth time. On 2 occasions, the SUV has entered Limp Mode while driving. I had the SUV towed for the first limp mode, and the dealer claimed it needed recalibration modules. I picked up the car and drove home eight miles, and the check engine light came on. I returned the next day for readings and TCM P0700, P1789, U0101, U220F. The dealer's solution was to recalibrate the gateway module this time. I drove the car about 20-ish miles, and at highway speeds on the freeway, I got limp mode again. Off to the dealership, having the SUV towed again. The dealership has claimed the electrionic car codes clear themselves and because of that they can't re-create the codes to find a solution. I am scared to drive my SUV, I do not feel safe in it let alone my children.

• ENGINE

  Recall notice received, went to dealer to have inspected and was told it passed the recall inspection. Oil changed from 0w20 to 0w40. Motor locked up less than 3000 miles later. My wife was 2 hours from home on the interstate on a Saturday night. Was forced to the left shoulder of the road pinned between concrete dividers and the fast lane. Had to wait 2 hours for a tow truck, $500 later the Yukon was delivered back to our driveway. Mind you, the electronic transmission can’t be shifted so it was dragged on and off a rollback in park 4 times. Dealer had it towed to their shop where they discovered the blown motor. 2 months later the replacement motor was installed.

• POWER TRAIN

  My vehicle previously experienced engine problems severe enough that the engine was replaced. Despite the engine replacement, the vehicle is continuing to experience an engine misfire, and the check-engine light has been flashing. A flashing check-engine light and active misfire are a serious safety concern because the vehicle may experience rough running, reduced power, hesitation, or potential loss of power while driving. The fact that the misfire continues after an engine replacement raises concerns that the underlying problem was not resolved or that another component or system is malfunctioning. The exact cause of the current misfire is UNKNOWN at this time. The vehicle and/or affected components are available for inspection upon request.

• ENGINE

  At approximately 58,565 miles, my 2023 GMC Yukon Denali equipped with the 6.2L L87 V8 experienced an internal engine failure. The vehicle had previously completed the applicable L87 engine recall remedy earlier in 2026. The vehicle developed a thumping noise and was inspected by an authorized GMC dealership. The dealer confirmed metal contamination in the engine oil and diagnosed a main thrust bearing failure. The condition was confirmed by the dealer and required complete engine replacement rather than a minor repair. The vehicle was out of service for approximately 31 days while the engine replacement was completed. GM authorized and covered installation of a complete factory replacement engine. The failed engine is available for inspection if requested. The failure created a significant safety concern because an internal engine failure of this type can result in loss of motive power while driving, potentially creating a hazard for the occupants and other motorists. I am aware that NHTSA is currently investigating L87 engine failures occurring after recall remedies. I am submitting this complaint because my vehicle experienced a documented internal engine failure after the vehicle had already received the applicable recall remedy and subsequently required a complete engine replacement. The replacement engine has not currently failed, and I am not reporting a failure of the replacement engine. However, I am concerned about the effectiveness of the remedy and whether the replacement engine incorporates updated or revised components intended to address the underlying failure condition. I have requested documentation from the dealership regarding the exact replacement engine assembly and whether it incorporates engineering or production changes related to the original bearing failure. That information has not yet been provided. No crash or injury occurred as a result of this failure.

• POWER TRAIN

  The powertrain malfunctioned and it at the dealership for an engine replacement. The vehicle lost propulsion on a 2-lane road while passing another vehicle. It cut off completely and started to decelerate. There was no warning or indication that this would happen and was dangerous in that I was accelerating to pass another vehicle when the event occurred. I was able to safely pull into a driveway, but the vehicle would not crank as it could not detect what gear it should be in. It was towed to a GMC dealership locally who confirmed 2 days later that the engine would have to be replaced. It is under warranty and will take 3-4 weeks.

• POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM

  My 2023 GMC Yukon AT4 with the 6.2L V8 has experienced multiple serious engine-related failures. The original engine previously was making a whining / knocking noise, then seized and required complete engine replacement under a GM recall/campaign involving 6.2L engine failures. The replacement engine later developed a lifter/valvetrain failure and required lifter replacement. The vehicle is now again exhibiting a pronounced rhythmic mechanical knocking/tapping noise, primarily during cold starts after sitting for an extended period. The noise occurs on most cold starts and has been documented in multiple videos. The vehicle is currently at a GMC dealership for inspection. I provided the dealer with several videos clearly demonstrating the noise. The dealer has stated that it has not yet been able to reproduce the condition and is attempting additional cold-start testing. The exact cause is currently UNKNOWN. No consistent warning lights or dashboard messages have appeared with the current knocking condition. My concern is that this vehicle has already experienced a catastrophic engine seizure, followed by internal valvetrain/lifter failure in the replacement engine, and is now again exhibiting abnormal mechanical engine noise. I am concerned this may indicate another developing internal engine failure that could potentially result in engine seizure or sudden loss of power while driving, including at highway speeds or in traffic. The vehicle and engine remain available for inspection, and multiple video recordings of the recurring cold-start knocking are available.

• ENGINE

  Vehicle became disabled. GM service center determined that the crankshaft failed and lifter rods bent causing total engine failure. GM service center unable to determine cause and the engine is being replaced at a significant out of pocket cost.

• ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM

  On August 22, 2026, I was driving my 2023 GMC Yukon Denali with the 6.2L V8 at highway speed when the vehicle began struggling to maintain power while climbing a hill. The engine then developed a noticeable knocking sound. Shortly afterward, the engine shut off completely while the vehicle was moving, causing a sudden loss of propulsion. I was able to bring the vehicle to a stop, but the engine would not restart. The electronic transmission also would not shift into Neutral and displayed a message indicating that the conditions required to shift were not met. Because the vehicle could not be shifted out of Park, the towing company had difficulty loading and unloading the vehicle. The failure occurred during normal highway driving and created a significant safety concern because the engine shut down without warning while the vehicle was in motion. I am aware of NHTSA Recall 25V-274 / GM Recall N252494000 involving certain GM vehicles equipped with the 6.2L L87 engine, as well as NHTSA Engineering Analysis EA25-007 concerning engine failures and loss of propulsion. At the time of this complaint, the dealership has not yet confirmed the specific mechanical cause of my vehicle’s failure. The vehicle is being taken to an authorized GMC dealership for diagnosis. I am submitting this complaint because of the sudden engine failure and loss of propulsion while traveling on a highway.

• ENGINE

  This car was subject to the GM Recall N2524940000 – This is related to engine failure in the vehicle. My Yukon Denali received the recall service on XXX at Liberty Buick GMC in XXX. It was determined that my engine would not fail and the car needed the heavier oil and a new oil filter. The car also received a 10 year warranty on the engine as part of the recall. XXX We were traveling down XXX Southbound on XXX headed to Atlanta to see family for Easter Break. My wife, son CJ (Age -XXX), XXX (XXX), and our English Cream Golden Retriever , Goose. We were traveling at 75 MPH on cruise control when a car came out in front of me. The car slowed down to adjust for the car moving out in front of us and then the engine completely shut-off and the car shifted into neutral. The car electronics turned off briefly, then came back on, with the dashboard saying “Push Start to turn on”. I hit the start button and nothing happens, I pushed the button several more times and still nothing happened. This occurred between 1:45 - 2:00 At this point, I begin to move into the right lane as we are approaching Exit XXX in [XXX]. I pull off on the exit, go about half way down and pull to the side, stopping the car. I place the car into Park and then push start on the car, nothing happens. I attempt to do this for about 5 Minutes and the engine still will not start and the car will not shut off completely (All electronics are still working). There were no warning signs that the vehicle would fail. The vehicle was inspected by GMC who determined that the engine had failed and would require full replacement.

• ENGINE

  While driving down [XXX] in [XXX] engine had a major failure causing the loss of power and control of the vehicle going interstate speed. Luckily no accidents and no injuries or fatalities. All the these vehicles using the 6.2L engines made by GM should be bought back by GM at full purchase price. A few months ago my vehicle underwent the recall procedure and passed. So the recall process is incomplete and shows no real problem solving procedures, These vehicles are a ticking time bomb to all the owners and fellow motorists.

• ENGINE AND ENGINE COOLING

  The contact owns a 2023 GMC Yukon. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal clunking sound. The contact pulled over and inspected under the hood. The vehicle was restarted, and the engine revved six times with smoke coming from under the hood. The contact stated that the transmission was previously replaced. The vehicle was towed to the dealer, who discovered that Jiffy Lube had used an incorrect engine oil during an oil change. The contact was informed to contact Jiffy Lube and file a claim. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 36,000.

• ELECTRICAL SYSTEM

  I have a 2023 GMC Yukon AT4. The OnStar/telematics system stopped working. The blue OnStar button does not function and the vehicle no longer communicates with the myGMC app, resulting in loss of connected and OnStar services. A GMC dealership diagnosed a failed OnStar/telematics module and advised that the module must be replaced at a cost of approximately $1,200. I am concerned because this failure affects access to OnStar communication and emergency-related services. I have found reports from other GM owners describing similar telematics/OnStar module failures, and GM has issued service information addressing K73 telematics-module communication faults. I have also opened a case with GMC Customer Assistance. I am reporting this because I believe the repeated failure of a system used for emergency communication warrants investigation.

• POWER TRAIN

  About 6 times during higher speed operation 80+km/hr during a downshift, the rear wheels lock up causing panic from screeching tires and sudden deceleration. Extremely unsafe. The vehicle is in with the dealership and as suspected, they can't find any issues with codes or transmission pressures. We even have a sound recording of the tires locking up. Typical symptoms of the valve body failure. Hopefully there's parts available soon.

• ENGINE

  2023 Yukon with 6.2; was "tested" at a local dealership in November 2025. Engine passed. Was given oil change with new oil/oil cap. In June of 2026, engine seized despite passing test in November & running the new oil since then.
