“The contact owns a 2015 GMC Yukon Denali XL. The contact stated that while driving at an undisclosed speed, gasoline would leak out of the fuel tank. The vehicle was taken to the dealer; however, the vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure. The contact related the failure to TSB Number: 14858 (High-Pressure Fuel Pump). The failure mileage was approximately 126,000.”Owner report · Fuel System, Gasoline · Feb 2022
“Faulty brake-light and costly fix. Dealership has taillight on back order so a replacement isnt even available. Dealership wants $675 just for the part that cant even be ordered. Dangerous to drive the vehicle with no solution available.”Owner report · Electrical System · Jun 2019
“My yukon makes very hard shifts when accelerating and decelerating. The tcm was reprogrammed after vehicle shut off on the high way last november. Now the truck shudders between 25 and 45mph especially when climbing or filled with passengers. Vibration can be felt through the cabin.”Owner report · Power Train · Jun 2019

“The wheels have corrosion and sharp edges have started to form. These sharp edges are putting pressure on the the tires causing them to lose air. We were required to purchase new wheels as the only solution. Wheels should last the life of a vehicle, not four years.”Owner report · Wheels · Jun 2019
“We have had both our taillights fail. The blinkers still function but because they are led they say they must replace the whole unit. Each side cost $672. That is outrageous for a taillight. There needs to be a way to replace each piece.”Owner report · Exterior Lighting · May 2019
“Vehicle has under 45,000 miles and both headlights need to be replaced due to malfunctioning led's from water intrusion. This happens after washing my car and now it will not pass state inspection due to driver side daytime led not turning on, and passenger side drl not turning off. I can not get this fixed because the passenger side light is on backorder, yet my local dealer said this isn't a known problem. Take a look on the internet and it's clearly a manufacturing issue (hence backordered headlights)”Owner report · Exterior Lighting · May 2019
“Tl* the contact owns a 2015 gmc yukon denali xl. While attempting to shift the vehicle from park into drive, the transmission made a hard clunking sound. Also, while driving between 30-50 mph, the vehicle vibrated abnormally. The vehicle was taken to lewis chevrolet buick of liberal (located at 202 n grant ave, liberal, ks 67901, (620) 624-2584) where it was diagnosed that the transmission fluid needed to be flushed and refilled. The vehicle was serviced, but the failure persisted. The manufacturer was contacted. The failure mileage was unknown.”Owner report · Power Train · May 2019
“Both rear light assemblies have had issues. Drivers side was first, brake light stopped working. Replaced under warranty. Passenger side brake light and parking light have now stopped working, just out of warranty. Problem comes and goes depending on temperature. I would think this would be considered a safety issue and be the subject of a recall since it is wide spread.”Owner report · Exterior Lighting · May 2019
“Approximately 51,000 miles on vehicle: rear passenger tail light is inop. We were on a trip when we noticed, if you tap the side of it the light would come on for just a second. Led strip for brake light is defective. Replacement cost is about $800 dollars. Lots of complaints and online forums regarding this issue. Gmc really need to resolve this isssue. These rigs cost way to much for that poor quality!”Owner report · Exterior Lighting · Mar 2019
“Led brake lights failed in both tail lamps. Led is supposed to be a longer lasting alternative to standard lights. Unfortunately the way gm designed these you cannot service or repair them like you can with a traditional bulb. After much research it appears that there is a thin strip that breaks in the circuit causing both taillamps to loose functionality, there is no bulb out warning so the driver is not alerted. And with no brake lamps this could result in a crash or injury.”Owner report · Visibility/Wiper · Mar 2019
