general problems of the 2024 GMC Yukon - part 2

Start transmission was replaced by dealer at 75 miles. 2nd transmission was replaced at 175 miles transmission was humming and slipped at around 30 to35 mph this was around April of 2024 August 1 2025 while driving at 45 dash board lit up went flashing and SUV slowed dramatically down to 30 mph got to dealership and they kept the vehicle for about a week and returned it with it being supposedly fixed. About mid October while driving at 60 mph it shut down again almost causing a wreck went to 30 miles per hour again. Hurt my wife’s neck when it reduced speed so quickly. Took back to dealership and I told them this car is dangerous this was with about 20 k miles been in shop was told it is scanning with 22 repair codes we have not had the car for 5 weeks and are trying to work with gm and dealer to get us out of it. But as of this report no progress. On interstate in city traffic this car will hurt or kill many people. I’m refusing to let my family or myself drive it. There is no warning when it will flash lights in dash and reduce speed. Also the front crash sensors went out and are currently not working we have all service records and paperwork that has been done including maintenance records we were given vehicle back with no warnings. I went to nita’s and ran VIN and it still shows issues. We are still making payments but driving a loaner car. The car is dangerous. I advised the dealer the first time it happened. I didn’t want it back. My wife went and got it and it sis it the second time and now she agrees it is dangerous contacted gm and they want to fix it but dealer implies they can’t ?. .

The contact owns a 2024 GMC Yukon xl. The contact stated that while driving at 70 mph, the vehicle lost motive power and decelerated. The contact was able to coast over to the side of the road. The vehicle was towed to the dealer and was diagnosed with crankshaft and rod bearing failure. The vehicle was previously included in NHTSA campaign number: 25v274000 (engine and engine cooling); however, it was determined that the engine was not defective and did not need to be replaced. The vehicle was scheduled for engine replacement, but had not yet been repaired. The manufacturer was informed of the failure, and a case was opened. The failure mileage was approximately 24,000.

My engine ticks, and during the winter, I noticed white smoke coming from exhaust pipes in cold and warm weather. I believe there may be an issue with my engine. My vehicle is not on the list provided, and I’m concerned that the dealership responsible for my oil change package will not identify the problem, possibly because newly hired mechanics may lack the experience to make an accurate diagnosis. I’m afraid my vehicle will be overlooked intentionally.

While driving on the interstate, I felt the engine "slip". Immediately afterwards, I heard a load knocking noise from under the hood, the check engine light came on, and the vehicle lost power. I was able to pull off the interstate. Called a towing company and got the vehicle towed to a GMC dealer. The dealership diagnosed the vehicle and noted a critical issue with the engine and transmission. Dealership recommends engine replacement. Vehicle is less than a year old with 15,400 miles on the odometer. This particular vehicle is not impacted by the GMC recall on their engine, however is has the same engine failure.

It’s been 7 months of the recall and dealers are not sending repair notices/remedy how is gm allows to take 7 months this is an untimely manner yall need to investigate further and issue buybacks I contacted gm saying the engine is making noise they they I have to pay for vehicle inspection…that is illegal.

On 15 Aug 2025, I was driving this vehicle on rte 151 in raccoon township with my 2 children when the vehicle suddenly and unexpectedly experienced a “loss of propulsion” with a corresponding uncommanded shift to “neutral”. Attempts to shift the car back into drive were met with a “parameters not safe” caution. I was fortunate enough that the vehicle behind me was able to slow and an accident was avoided. The thought that this could have happened with my family on the highway, during adverse conditions, or any other scenario is frightening to say the least. Other owners of affected models weren’t as fortunate.

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. I am a retired general motors safety engineer and I know I was not pressing the gas (accelerator) pedal when this sudden acceleration event occurred. I believe this type of event occurred one other time while I was driving this vehicle. However, I am not as clear about the circumstances surrounding this previous event.

I am filing this complaint regarding gm recall n252494000 (NHTSA campaign number 25v274) for my 2024 GMC Yukon xl (VIN: [xxx] ). The issue involves a serious engine defect related to the crankshaft and/or connecting rods, which can result in catastrophic engine failure and loss of propulsion while driving—a clear and dangerous safety risk. I first became concerned when early reports of this issue began circulating publicly. As a father of young children, I became increasingly uneasy that my vehicle could potentially fail while in operation. Receiving gm’s formal recall letter only validated my growing concern for my family’s well-being. It’s deeply frustrating and unsettling. The notice states that parts to repair or replace the engine are not currently available, and offers no clear timeframe for when a remedy will be provided. I feel like we are being strung along while forced to continue using a vehicle that may become unsafe at any moment. This delay is unacceptable. There has been no offer of a loaner vehicle, no proactive communication from the dealer, and no assurance from gm that they are prioritizing driver safety over logistics. I am requesting that NHTSA investigate whether gm is doing enough to provide timely remedies to affected customers. I also urge you to consider whether interim solutions (such as alternative transportation or more aggressive recall execution) should be mandated. Thank you for your attention to this matter.

The engine seized on us. It only has 18,000 miles on it. This could have caused a serious accident! there was no warning, no indication, it just died and would not restart. We had to have it towed over an hour to get to our closest dealer (and don't get me started on how they treated me!). We were stopped at a stop sign at the intersection and it just died. Thankfully we weren't driving down the highway or in the middle of traffic, we just ended up blocking people from using our lane for quite sometime. The cops were called for traffic control, but no police report was filed.

I am the owner of a 2024 GMC Yukon denali/at4-t1, currently subject to gm program #n252494000 for the l87 engine loss of propulsion engine defect that can cause sudden engine failure, loss of power, and safety hazards. My vehicle has approximately 18,000 miles and is my primary mode of transportation. Gm has informed me that I cannot request an immediate inspection and that they are randomly selecting affected vehicles for inspection without a clear timetable. This means I must continue driving a vehicle with a known safety defect that could fail at any moment — creating an unreasonable risk for myself, my passengers, and others on the road. My dealership has confirmed they cannot perform the inspection until gm activates my VIN in their system. No estimated timeframe has been provided. Given the severity of the defect and the potential for catastrophic failure without warning, I respectfully request that NHTSA investigate gm’s phased approach to inspections and determine whether this practice is consistent with the safety obligations under 49 u. S. C. Chapter 301 and related regulations. I also request guidance on how I can have my vehicle inspected immediately to mitigate risk. Thank you for your attention to this matter.

There currently is a serious recall on this vehicle and there is no remedy available. I’ve called the dealership and they confirmed this information.

Engine started making noise no codes no alarms pulled off hwy had to have it towed to dealership. Service told us needed to replace engine had no time frame on when vehicle would be returned.

The contact owns a 2024 GMC Yukon. The contact stated while driving 55 mph, the accelerator pedal was depressed and the vehicle failed to respond, with the vehicle sputtering. The contact stated that unknown warning lights were illuminated, and an unknown message was displayed. The contact pulled over to the side of the road as the transmission shifted into neutral. The vehicle was shifted into park and turned off. The contact then attempted to start the vehicle; however, the vehicle failed to restart. The contact then towed the vehicle to the dealer and a diagnostic test was pending. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 11,000.

The motor is randomly revving at braking so far only under 10 miles an hour. Yesterday it stalled twice on me and cut off braking under 10 miles an hour. I had to come to a complete stop while restarting the vehicle. Definitely has me worried if it happens on the highway or higher speeds.

Driving on highway. The vehicle jerked and started to make squeaking, clunky sounds. Gas stopped flowing to the vehicle. Then the vehicle became inoperable. No warning light or alerts or sounds occurred before or after. It was a complete surprise.

On March 21, 2025 my 2024 GMC Yukon denali's engine died while driving 80 miles an hour down the highway with my family. We were able to coast to the shoulder. The vehicle would not restart. We called a tow truck. When the tow truck arrived the vehicle started but we decided to take the vehicle to closest GMC dealer. They ran diagnostics on the lights that were showing on the dash and nothing was reported. They had no recommendations. We were 3 hours from home returning from spring break so we decided to keep traveling. We made it about 120 miles and again the engine died while traveling 70+ miles on the highway. We were able to safely coast to the shoulder. We called a tow truck and the Yukon was towed to the local GMC dealership. The next week it was reported to me that the Yukon would need a new engine. The 1, 3, 5 rod bearing had spun and the 3rd trust bearing had spun. Since there were no rental cars in the city available we rented a u-haul truck and drove 2 hours home. Almost one month later we are awaiting the new engine to be delivered.

While driving down the interstate the vehicle lost power without warning and gave a command to "press start to resume" tried to do that but nothing happened. Eventually we were able to get over to the shoulder of the interstate which was super busy in atlanta. Once we stopped, we shut off the vehicle and it started back up, and we proceeded to get back on the interstate, when the same thing happened. We stopped again, waiting a few minutes and were able to get back on the interstate and complete out trip without any issues. 3 days later while driving on the interstate again, the vehicle had a weird winding noise coming from it. Once I was able to get off the instate the engine was knocking very loudly and had no power. Got the vehicle to our home and had it towed to the dealership the next day. Dealership gave the diagnoses that a new engine, radiator and engine coolant lines needed to be replaced. The vehicle had 2,248 miles on it and was purchase 2. 5 weeks prior. No eta on when we will have a new engine and our vehicle back.
