Chest Clip, Buckle, Harness
After my child had thrown up all over the car seat her father had taken her inside to clean up and I took the car seat apart to throw the pieces into the washer to clean them. The harness strap did not come out fully clean so I contacted Graco for a replacement piece and I was told that they don’t replace those and that the strap being removed totaled my car seat. It has a woven material tab that goes up through the hard plastic base and locks in by opening itself. It’s essentially a T in the material so it can be folded to go back through the hard plastic base. I was told that since the manual doesn’t provide instructions regarding that piece that I should know it’s not to be removed. No where in the manual, on the car seat or on the strap says it’s not to be removed. I did not damage/break/cut any pieces to get it in or out of the car seat. I was a mom in a panic trying to clean the car seat as quickly as possible so I could tend to my sick child. There were no warning signs telling me anywhere not to remove it. I don’t want other parents to do what I did and have a totaled car seat that they continue to use. I did not have the manual at the time of removing the pieces for cleaning but I have since located the PDF and read through all 96 pages.

ENGINE
I perform all maintenance on my vehicles, I have previously been a ASE Certified Master Technician, so I know engines and vehicles very well. Vehicle is outside of current engine recall window due to the engine build date being July 15, 2024. Engine was over maintained, oil and oil filter changed 6 times in 17,732 miles, first oil and filter change performed at 544 miles, when 5W30 oil was put in engine, installed a magnetic drain plug and installed Filter Mags on oil filter. Ran 5W30 oil for 2 oil changes, then moved to 0W40 oil. Oil analysis performed for each oil change. Results were looking acceptable up until the next to last oil change at 13,801 miles. Changed engine oil and filter on 6/12/2026 @17,732 miles. Found a heavy build up of metal particles on the magnetic drain plug and when oil filter was cut open there was a heavy build up of metal particles where the Filter Mags were located and the filter element had fine metal particles in entire engine oil filter element. The engine has made no noise and is still running, but based on the evidence the engine is currently failing and if I would have continued to drive it, the engine would likely lock up on the highway. CLEARLY GM DID NOT solve the crankshaft problem July 1, 2024 and CLEARLY using a higher viscosity oil like 0W40 will not keep these engines from failing. If I would have continued to drive the vehicle and if I would have not changed oil and found metal in the oil, this engine would have absolutely failed on the highway. This vehicle has over 80% highway use.

POWER TRAIN, ENGINE
My wife and I were traveling to Denver CO to pick up my son and grandson from the airport. The engine started to make a very exaggerated rattle. We found a dealership near our motel where we took the vehicle to and were told not to drive home that the engine needed to be replaced. We had to arrange our own transportation for both us and the vehicle 8 hrs back to our home in Rapid City, SD where our local dealership replaced the engine. The vehicle had approximately 65,000 miles when this occurred. Fortunately we were in a populated area when this occurred as there is a lot of very sparsely populated area between our home and Denver. This malfunction not only cost me a lot of money but also put my family at risk in unfamiliar areas.

ENGINE
2024 Engine failed while moving at 70mph out of state. De-accelerated rapid as I was changing lanes and was almost hit by two vehicles. Once of the interstate, I made it to the shoulder of an exit ramp that was a blind spot. Cars exiting to this ramp almost always had to veer to keep from hitting me. I purchased this vehicle in October 2024, never knew anything about a recall, was never disclosed to me about recalls. To this day, if I enter my VIN, there is no recall and I have never received any communication stating this vehicle was on recall. I complained to the dealer twice about unusual noise from vehicle, which they dismissed. I took it back to the dealer because my oil light indicated I was "low", this oil is too low, my concern was a leak. Took into GMC dealer, they stated we did not see any leak. Now this. Problem, GA law states in order to qualify for buyback, 24,000 miles or under 2 years. Well, I have 24,986...this automatically disqualifies me. SMH The options I was given are all a NO WIN for me! I was almost killed on the interstate, not to mention the level of stress and issues this car nightmare has caused me. $100k vehicle and I still owe 87K

On May 6, 2026 while driving on the interstate, the vehicle automatically shifted into Neutral, and lost all engine power. The vehicle would not shift back into drive or even 4x4 neutral to be towed. The vehicle was towed to Sam Boswell GMC in Mt Dora, FL. The engine had seized up, and there were metal shavings in the oil filter which indicated a catastrophic mechanical engine failure.

ENGINE, SEAT BELTS, POWER TRAIN
While I was driving home from the grocery store with my 4 kids our 2021 GMC Yukon XL (5.3L V8 engine), the vehicle suffered a sudden, catastrophic mechanical engine failure without warning. The engine began violently shaking, lost major propulsion, and dropped into a severe misfire state when we were coming down the highway. This created an immediate safety hazard on the road, as I suddenly lost the ability to safely accelerate or maintain highway speeds while hauling my children.A certified technician diagnosed the issue as a complete failure of the active fuel management hydraulic valve lifters and bent pushrods, a known manufacturing defect explicitly documented in GM Technical Service Bulletin PIP5776F. The internal failure required a total engine teardown and valvetrain replacement, costing over $10,000 out of pocket.General Motors has failed to issue a safety recall for this specific 5.3L valvetrain defect, despite it causing unexpected engine stalls, severe power loss, and immediate traffic hazards for drivers. This defective component poses an ongoing safety risk to families and should be upgraded to a mandatory safety recall. I am afraid to drive it every time I get on the highway in fear it could shut down again.

The engine light came on and started making noise. We drove it to a mechanic shop, and they said the code stated camshaft and other component issues, but the engine ended up failing completely and was rebuilt. We initially checked for recalls and our VIN did not show any; however, we recently became aware that our engine (6.2L) might be part of the ongoing current problems associated with a recall. We are hoping that GMC will cover any remaining repairs and/or reimburse us for the thousands it has cost us.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
While operating the vehicle, I began to hear a metallic grinding noise originating from the center of the engine compartment. The sound was clearly audible within the cabin. Approximately one mile before the vehicle ultimately failed, the engine began to malfunction. As I slowed to a stoplight, the vehicle started to shake before shutting off abruptly and entering a coasting state. All electrical systems powered down and the vehicle would not restart. Shortly thereafter, heavy smoke began to emit both inside and outside the cabin, visibly coming from the hood and through the air vents. There was also a distinct burning odor. I attempted to restart the vehicle multiple times without success. The dashboard displayed the message: “conditions not suitable to shift.” Due to the vehicle becoming disabled on a curve and posing a safety hazard, I contacted the Sheriff’s Office for assistance to prevent a potential collision. Upon their arrival, it was noted that the engine compartment and hood area were exceptionally hot, particularly where the smoke was originating. The dealership has since confirmed they have also been unable to restart the vehicle. The vehicle has been inspected by the GMC dealer and is currently pending further evaluation by a GM-certified mechanic to determine the root cause. Prior to this incident, there were no warning lights, system messages, or other noticeable symptoms indicating an issue.
