GMC Yukon XL Reliability by YearBest & worst years, problems & recalls — NHTSA data

Engine failed, no check engine lights turned on. Needed to have the truck towed to a dealer

The car was purchased on 8/15/2026. On November 6th 2026 with 3051 miles on all the gauges, electronic dashboard, gps , climate controls, heads up display failed while car was in driving. There was no way to tell what speed the car was going, the gas level, rpms, engine temperature, etc. Navigation failed, Cruise control failed, I was unsure if the emergency braking system failed. The dealership responded there was over 27 error codes on the car computer. There was no way of knowing if the signal lights were working. There was no prior warning to this failure. The GMC service department at the dealership confirmed the failure and said it needed to replace the radio control module. It took 70 calendar days for a replacement module to be provided, and a new software patch was uploaded after several attempts. After the vehicle was repaired the dealership acknowledged that they have been seeing this problem. GM has failed to provide any other assistance.

The infotainment and instrumentation cluster will reboot while driving. This has happened multiple times while on the express way and while using super cruise. When the event happens the infotainment and instrument cluster will turn black for multiple minutes rebooting. At times they do not successfully reboot and forces the vehicle to pull over stop and force a system reset.

Starting at around 1300 miles, we noticed jerking upon acceleration. We took it into the dealership at 1500 due to a check engine light. They replaced the coil in cylinder 1. Then again at 3200 miles, we took it back in for the jerking sensation. They could not replicate the problem. At 4380 miles, we took it back to the dealer for the same issue. They drove it 580 miles and found the lifter valves in bank 1 to need replacement. The repair was performed and then on Saturday 1/17/2026, the car started giving check engine lights every time we accelerated. It would jerk non stop. The car hesitates during acceleration and feels like someone is pressing on the brake as we are accelerating, causing a jerking motion. Coming from a stop, the car feels like it has a hard time accelerating, almost like it is moving against a hard force to try to come up to speed. The car is at the dealer again today for this issue. It is unsafe to drive due to the hesitation during acceleration.

Vehicle Status: Brand New Current Mileage: Approximately 10,000 miles Incident Description On 1/8/26, while operating the vehicle on the interstate at highway speeds with cruise control engaged, the Check Engine light began to flash. Simultaneously, the vehicle’s warning system issued an alert stating that the engine oil was excessively hot. Immediately after these warnings, the engine began to emit a loud knocking sound and lost all power, shutting off completely while in motion. I was able to safely maneuver the vehicle to the shoulder of the road. Post-Failure Observations Upon inspection under the hood, I noted the engine was radiating extreme heat. I allowed the engine to cool completely before attempting a restart. While the engine attempted to turn over, it failed to start. Diagnostic Alerts Following the mechanical failure, I received multiple critical notifications via the GMC mobile app citing various engine failure errors. Summary Given that this vehicle is brand new with only 10,000 miles, a catastrophic engine failure of this nature is unacceptable. The vehicle was being operated under normal highway conditions when it became inoperable, posing a significant safety risk. I am seeking a full diagnostic review and a permanent resolution under the manufacturer's warranty.

The image module system has completely failed and never worked in the Yukon. Then it would brake while still accelerating.

I purchased this vehicle in May of 2025. It currently has 9840 miles on it. While driving in October the vehicle shut down and locked up. After getting it towed to a dealer I was told the diesel motor and the fuel system were blow and seized and need to be replace. The vehicle is still currently in North Carolina while I live in Virginia. Supposedly parts are in for repair for 3 weeks now and I still don't have my vehicle nor any info on when I will get back. Davenport GMC of Rocky Mount and GM have been rather useless in this process. I cant believe I am going through this with a $90,000 car that was four months old.

Reduced engine power warning light came on at approximately 7600 miles on our new 2025 Yukon xl. Dealer inspected and ultimately decided the engine needs to be replaced due to crankshaft end play out of spec. This is a know GM issue. Incorrect thrust bearing was installed from the factory. Gm did not inform us of this issue. This could have resulted in catastrophic engine failure and cause to be stranded on the road. Not ideal when it is -20 degrees in my hometown. Dealer finally replaced engine then had lane departure unavailable and lane assist unavailable warning lights. Dealer claimed this was unrelated but all safety equipment worked when we dropped it off. Now it doesn’t.

My brakes stopped working randomly. Alarms started going off in the car. Thankfully I was able to quickly turn right instead of rolling into traffic. This was terrifying and could have caused a very serious wreck.

DuraMAX 3.0L LZ0 engine with defective crankshaft thrust bearing caused catastrophic engine failure requiring engine replacement. The event occurred at about 1,000 miles. There is a GM TSB that addresses this issue. This failure displayed all of the symptoms as described in the Technical Service Bulletin (TSB) 25-NA-307. The engine has been replaced by GM. There was only one cryptic dashboard message that "acceleration may be reduced", that briefly appeared and then disappeared, three days before the incident. With no check engine light, the mysterious message was chalked up to possibly a DEF low warning. DEF was added. The vehicle displayed no problems during those three days -handling normally. Then while at interstate speeds approximately 90 miles later, the warning that "acceleration is limited" flashed and the vehicle went into limp mode, shortly thereafter the check engine light illuminated. OnStar read the code - P06DD. The email from them stated the recommended action: "Service within 7 days." The following morning the vehicle was presented to a GM dealership service department. Loud "knocking" noises were originating from the rear of the engine compartment at that point in time. The service department reported the engine needed replacement and did so.

I am writing as the owner of a new 2025 GMC Yukon XL AT4 VIN: [XXX] , purchase date: 01AUG2025, from Elizabeth City GMC, Elizabeth City, NC. This vehicle, equipped with the 3.0L Duramax diesel engine and Super Cruise hands-free driving assistance, was purchased for safe family travel, including space for my wife, our 21-year-old daughter, and our family dog(s). At approximately 4,300 miles—well within the 3-year/36,000-mile bumper-to-bumper warranty—this truck suffered a catastrophic right-rear brake failure directly attributable to a dealer-installed GMC-approved Brembo Performance Brake Upgrade Package, resulting in a near-fatal highway incident and profound emotional hardship for my family. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The rear view camera is not sufficient for full time use. The camera is positioned too low and during times of dawn/night/dusk if a truck of similar size pulls up behind you, your camera is completely blinded by headlights. Leaving you unable to see anything in the rear view camera. This is a serious safety concern as you are unable to see if anyone is approaching your vehicle to cause you harm. The low camera placement also does not allow for an acceptable/comparable view as using the rear view mirror. The zoom does not pull out far enough to see multiple lanes of traffic and even during the daylight, if someone is approaching the vehicle to cause you harm, it would not be visible. The camera placement only allows you to view the front grill or hood of the vehicle behind you.

Transmission malfunctioned 4 separate times. Engine and service transmission light came on. Vehicle shifted hard and became immobile at certain times. 4 tropes to a dealer for repair. Latest repair was replacing ECM and problem still persists.
