SERVICE BRAKES
I have owned this vehicle almost 6 years, 40,000 when purchased used. Since purchase, we have had multiple issues with the trailer brake system randomly going off, dinging non stop, we had the problem serviced under our warranty and is now going off again. We do not tow but a few times every summer which is our jet skis however. This has happened multiple times prior to us using our warranty, the garage says they fix it but it keeps happening. I am very frustrated that I can't drive my vehicle down the road without a continues dinging. I looked up what "trailer brake system" means and found that it can be very dangerous and GMC's are known to have this problem, it is suggested that I lodge a complaint in hopes of getting this problem resolved from the manufacturer before a driver becomes seriously injured when the braking system decides to fail. I have read complaint after complaint. My warranty is now expired as I recently rolled over 100,000 miles, the GMC garage told me the part was around $78 but over $400 with install, ridiculous! I have already replaced this part a little over a year ago, I went to the garage where the warranty work was performed and got all the paperwork. Why has this problem not been categorized as a recall at this point? Something isn't right!

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving on the interstate on a low speed and my SUV came to a complete stop with no notice. Nothing was in the road or close in front of me. Jerked me to the front and seat belt left a red spot on my neck from the seat belt, scared the crap out of me. I thought I was hit from behind. The is a hug safety concern that needs to be recalled and fixed immediately before it causes an accident.

AIR BAGS, SUSPENSION
My 2022 GMC YUKON DENALI has been at dealership multiple time for defective air ride suspension. The message says "service leveling system" once that show's it's a matter of time the vehicle will slump down. The passenger side air bag keeps busting creating a safety hazard for my family and others on the highway.When problem occurs the vehicle slumps down on front suspension and will bounce out of control when driving on highways and over bridges. It has now been in shop 4 times for the same problem. Dealership has been extremely helpful on trying to fix the problem, but there's definitely something serious going on and GM needs to look into making this right before someone get's hurt driving this vehicle.

SERVICE BRAKES
Ambient temp was 100 degrees for reference. Had been driving about 5 hours. Went to stop and had no power assist for brakes. This continued for at least 20 miles. Stopped and confirmed vac hose was connected. I tried to remove vac hose to check for vac at booster but was afraid I might break the part. Electrical plug at vac hose booster connection was secure. Continued driving and it began to work again. Condition: brake pedal took considerable foot pressure to apply brakes. Zero power brake assist was available. My qualifications; a past ASE master teck.

EXTERIOR LIGHTING
Rear brake lights fail due to an issue known by GMC - MULTIPLE GMC YUKON and YUKON XL have this issue. All within the same year. The metal connector in the Brake housing fails and requires it to be soldered or a complete replacement costing consumers $800+ for replacement. A severe safety issue as the Brake Lights quit working!!

FUEL/PROPULSION SYSTEM
The vehicle was not starting and after 3 attempts it started, but a strong smell like gasoline came inside the car, and as I checked, fuel was running all the way to the ground. Major hazard! The vehicle was taken to the dealership and diagnosed with a leak in the High-Pressure Fuel Pump. According to the service advisor NOT COVERED under powerterain warranty. The part just went bad, and needs to be replaced. However, the vehicle has been in the service department since July 3 (Now it is July 18) and the part is in back order and no news as of when my vehicle will be fixed. My vehicle is a 2021 and I do not understand how a part is not available, or discontinued (according to parts department). I need my vehicle fixed!

ENGINE, ELECTRICAL SYSTEM
This complaint is an addendum to a complaint I filed last week regarding the suspension of my same vehicle. 1. Battery: battery died several times without warning and the cause was never found. Took 4 trips to the dealer to get a new battery placed. Dealer blamed various “modules” each time. I believe that electrical system is faulty because the windshield wiper sprayer also stopped working, and the heads up display flickered at times. Issue 2: “low engine oil pressure warning. Turn vehicle off immediately” warning at 17,800 miles while driving on the highway. Had to immediately pull over and per GMC, the vehicle was not able to be driven and had to be towed to the dealership, leaving me stranded at night in a vehicle that I couldn’t turn on while I waited to be picked up.

ENGINE
The lifters failed about two months from buying it from the dealership. The vehicle was new and only had 13 miles when it was bought. The vehicle had about 600 miles when the lifters failed. As he vehicle was being driving on the highway it started making a clicking noise and the engine would pull and lost power. The vehicle was taken to the dealership and was in service for about 3 weeks for repairs. No one other than the dealership has inspected the vehicle. There was no warning lamps, messages or symptoms prior to the failure.

SUSPENSION
We repeatedly received an error saying “Vehicle too high, drive with caution”, at which point, the suspension adjustment controls would not work and I could not lower the vehicle. The service department has had our vehicle for over 2 months now and I am unsure if they were able to duplicate this particular issue, but we did photograph the warning. We have had multiple other electronic issues with this vehicle and feel we were sold an unsafe vehicle.

FUEL/PROPULSION SYSTEM
Fuel pump leak. our cabin fills up with exhaust causing myself and my 3 young kids (1,3,5) to start coughing, eyes and throat burning, headaches & a hard time breathing. confirmed by GMC dealer in concord & separate auto shop. They told us it had a recall and that they couldn't fix it after paying them to diagnose it since it was recall. Now GMC dealer is telling us that the problem and recall exists for other 2015 Yukon models but our VIN # Is not included and that's why they never fixed the problem that I've been complaining about since I bought the truck (dont remember exact purchase date but the vehicle was new and under warranty for years). I've taken it to the dealership 3 times for the same problem (exhaust smell in cabin) and they kept saying it's fine. Now it's so bad that we can't drive it because it makes us feel sick.

It started shutting off at a light for autostop.but when it would turn green it would intermittently just drop out of autostop without restarting. Then may start back up or maybe not, many time after restarting at the light it would died in the middle of the inspection. A parasitic draw kept killing the accessory 12 V battery replaced the 12 V battery but the problem continued. When the truck was running it would run flawlessly,before stalling. The code said to replace the auxiliary fluid pump. I had it a new auxiliary fluid pump installed. After this the vehicle wouldnt crank. They then worked through a service bulliten fixing a list of areas were the harness was chaffed and shorted. The truck has been out of commission the past 10 months and intermittently started twice during this time, it ran rough for 5 mins and died out at the first stop sign and wont crank again. Some times it will crank but not start.
