SEAT BELTS
Both second row seatbelt retractors have had issues retracting. We had them checked today while our car was in for other issues. Both seatbelt retractors are broken and need replacing ($1600). Without replacing them, the passengers using those seats would be at grave risk in an accident. We are the original owners of the vehicle, our young children are fastened in their booster seats with parental help. There has been no extreme wear and tear or any abuse to the seatbelts.

POWER TRAIN
The contact owns a 2018 GMC Yukon XL. The contact stated that while her husband was driving 20 MPH in two wheel-drive(2WD), the vehicle started reversing while the transmission was in drive(D).

The vehicle was driven to the grandparent's residence, where it was parked. The check engine warning light was illuminated while the transmission was in park(P). The vehicle was then towed to an independent mechanic, who replaced the torque converter, the transmission, and several other unknown parts. No further information was available. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 102,000.

SEAT BELTS
Both seat belt retractors seem to be failing and something inside the retractor is cutting the seat belt. I had to replace the right seatbelt because it snapped after it was rubbing on the retractor inside the body. Now it seems the left side is having the same issue. The left seatbelt now will not retract and it looks like it's been rubbing also so eventually it will probably break.

SERVICE BRAKES, ELECTRICAL SYSTEM, SUSPENSION
We just purchased this vehicle from Winegardner GMC in Prince Frederick, MD. On [XXX} on our drive home from the dealership, we kept hearing a terrible screeching/ clucking noise coming from the rear when we were braking or applying any pressure to the brake pedal. We instantly contacted the dealership and they had us bring the vehicle back the next morning for them to look at and to make the repairs but unfortunate for us. They do not have the parts in stock, so we have to take it back Tuesday, October 8 , 2024 at 8am and leave it for the day. Hoping it is repaired correctly with the new parts “both rear calipers” As I left the dealership, I was approximately 10 miles away and out of no where my dash displayed “service, trailer, brakes”, constantly along with a loud dinging noise for the rest of the drive home. I contacted the dealership and spoke with the service manager and informed him of the situation. He told me it has been an ongoing issue with GM for years and it’s electrical and because we purchased a used vehicle. It’s not covered to be repaired. We would have to pay out-of-pocket for it to be fixed. This is very upsetting because we just spent $40,000 on a used low mileage Yukon Denali for our family to travel in, but it’s unsafe, because it affects the traction control, and ABS brake system. I would also like to note that I did not have a trailer hooked to the vehicle, so I do not understand how that service indicator would appear unless it was cleared by the dealership during Maryland state inspection. We have asked them several times for a copy of the Maryland State inspection they performed, and we are getting the runaround. As the purchaser of a vehicle, it is all right to have that document, showing what past and what failed Maryland inspection before being resold to us.

POWER TRAIN
Vehicle started accelerating and loosing power randomly on highway traffic in [XXX] . Sudden jerking behavior was very dangerous and unpredictable and non controllable upon investigation at the shop, mechanic found it was transmission issue, clutch was slipping and engaging randomly, had to pay over $5500 out of pocket to rebuild the Transmission As GMC had recall for same issue for different year Yukon but not for 2018. This should be part of recall as it can be very dangerous and life threatening situation specially on highway speed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

SUSPENSION
I own a 2018 GMC Denali, Yukon XL SUV, with 67k miles. While towing our 24’ Airstream (weight 4400 lbs) the vehicle excessively bounced in the air several times on a flat pull on I-80 in Northern Ca. I took it to three mechanics who told me that the front magnetic and rear air shocks had all failed and were leaking oil. The best price that we could secure for replacement is $2500. Each mechanic commented about the frequency of this type of failure with GMC and stated that this should be a recall because of the risk of trailer detachment/failure. I’ve owned dozens of vehicles in my lifetime (age [XXX]) and have never replaced a set of shocks before. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
The air-conditioning (A/C) unit in my 2018 GMC Yukon XL (my vehicle) is not blowing as cold as usual. The dealership (Westpoint GMC) where I purchased my vehicle says their A/C department is backed-up and that I would need to leave my vehicle with them for 2 to 3 days to run diagnostics. I took my vehicle to another General Motors dealership instead, Westside Chevy, and their A/C department or technicians state that my vehicle has a leak in the rear evaporator coil after running their leak detection tests. I purchased my vehicle new on May 4, 2018, and have not any mechanical issues nor heating, ventilating, air-conditioning (HVAC) issues since ownership. This mechanical flaw / malfunction / disruption in the cooling comfort of my vehicle during this extremely hot weather puts the life of other drivers and myself at risk of injury or fatality due to discomfort and inconvenience while driving. There are no alerts or alarms associated with the failure of this mechanical component within the HVAC of my vehicle. This condition first appeared on September 30, 2023. I understand that a possibly similar or related investigation in other GM vehicles took effect in February 2016 under Technical Bulletin 16-NA-046. Is it probable that there is a design flaw within the 2017-2019 GMC Yukon, Yukon XL and other similar builds HVAC?

ENGINE
Engine Valve Lifter for cylinder 3 had failed and Camshaft lobes damaged. Error codes of P0300 and P0303. Vehicle had 67,049 miles when I brought it in to be repaired at Park GMC in Greenville, SC on 12/28/2022. GMC has the lifters (they replaced all 8) and the camshaft. Failure happened while on I40 in the Smokey mountains at night while driving back from Dollywood with my family. Engine produced a gassey sputtering sound and I lost some power but only noticeable under acceleration. Had another lifter failed due to the worn camshaft lobes, we could have easily been rear ended. A year prior to the failure (September 2021), I had taken the vehicle to a Wakefield Buick GMC and Parks Buick GMC to be inspected due to a shake at idle. Both dealerships said there were no codes and they didn't know what was wrong but they could feel the shake/vibration intermittently at idle. In November of 2022, I got the P0303 error code and took this vehicle to a private mechanic (since dealerships previously said nothing was wrong) who diagnosed an issue with the fuel injector for cylinder 3. I had mechanic replace all 8 injectors and he cleared the code. About 150 miles later (while on I40), the code came back. I took this vehicle back to the private mechanic and after several weeks with my vehicle, he refunded me the labor and said it was probably an issue with the lifter but he didn't have time to take apart the engine. I then took this vehicle to Parks GMC in Greenville, SC where they diagnosed a lifter and camshaft failure. Lifters and camshafts should not be failing in vehicles with under 100k miles.

ENGINE
The engine started making a ticking sound a few days after thanksgiving. I made an appointment with the dealership but they couldn’t take it in for 3 weeks. The day before my appointment I was driving on the highway and the lifter broke which caused the camshaft and a few other parts to break causing sudden lose of power and severe shaking. The parts for the repair were back ordered and it took about 5 weeks to get my vehicle back. About 7 weeks later I started the car in the driveway and it again had lose of power and severe shaking. The parts that were replaced in January failed and ruined the whole engine. There is a 6 month back order on this engine. It has been sitting at the dealership for almost 2 months already. Both incidents I believe had the potential to cause an accident if I were driving with cars close behind me.
