2017 GMC YUKON Complaints

1) LED tail-lights fail intermittently - this is a known problem GM does not proactively address unless customers complain repeatedly. Puts driver and passenger in danger. this began happening at 25K miles. 2) AC condenser fails - GM will not address as part of a broader recall despite extensive late model customer complaints. This put passengers in danger on any road trip across desert terrain. GM has been unresponsive despite numerous calls asking for resolution. This occurred at 36k miles. 3) Electrical failings - numerous electrical failings - from entertainment system (at 10k miles), starter motor and internal lighting - all failing at 36k miles. NHTSA must take a look at these manufacturing defects - they are putting customers at risk!

led lights are malfunctioning on my 2017 Yukon xl. causing my brake lights to flicker and then go out completely. I've been pulled over and almost hit from behind due to these lights not working correctly. they have to be replaced by completely removing and replacing the entire light fixture for the high cost of 800+. they are not built to be fixed, just replaced. What's worse is that replacing them only buys you a little time before those again go out. its unsafe and puts my family at risk daily.

The vehicle is misfiring and rough idling while driving. This vehicle has four of the eight fuel injectors misfiring while in operation. Although the dealership only diagnosed two of them I took it to another shop who diagnosed that 4 and 8 are also misfiring.

The brake lights fail. First the left light failed, and two days later the right light failed. After researching, this is a common problem with GM and these models. The fix is not just a bulb- the whole rear light assemblies (each side) needs replacing with GM price quotes of $900 a side. We were over 1000 miles away from home.

There is a known issue with the GMC strutts leaking. I contacted several GMC dealerships to purchase strutts so that a local mechanic could put fix my truck without the dealership pricing. GMC refuses to sell the parts to anyone other than a dealership. I was informed by several dealerships the part is a national back order for 6 months. The cost that GM is making for each person that purchased a 2017 Denali is between two to four thousand dollars!! While driving my truck myself and my daughter would come out of the seat! This should be a recall. I'm also reporting this to the consumer financial protection bureau. I phoned this in a month ago and have heard nothing.

The contact owns a 2017 GMC Yukon XL. The contact stated while driving at various speeds, the contact noticed that the passenger rear tail light was inoperable. The contact stated no warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed with the tail light unit needing to be replaced. The vehicle was not repaired. The contact was relating the failure to an unknown recall. The manufacturer had not been informed of the failure. The failure mileage was approximately 106,632.

The contact owns a 2017 GMC Yukon Denali. The contact stated that while driving over a bump in the road at various speeds, the vehicle became airborne. The contact took the vehicle to the dealer who diagnosed the vehicle and informed him that the struts failed and needed to be replaced. The vehicle was not repaired due to the parts being on backorder. The manufacturer was made aware of the failure. The approximate failure mileage was 100,000.

Passenger side brake light goes in and out and often time stays out. I have read about numerous other people dealing with same issue as it is a manufacturing/quality issue. This is very dangerous. GMG apparently puts the same faulty brake parts back in car while under warranty then when the issue arises again when not in warranty sell customers a pricey part that actually works. Again, very unsafe and terrible business practice as well.

ABOUT 500 MILES PAST THE ORIGINAL POWERTRAIN WARRANTY OF 60,000 MILES, THE TRANSMISSION FLUID TEMPERATURE SENSOR FAILED. I KNOW THIS BECAUSE AN ENGINE LIGHT CAME ON DISPLAYING P0700 AND P0711 AND THE GAUGE ON THE DASH IS ERRATIC. I DID RESEARCH, AND THE TRANSMISSION FOR THESE VEHICLES MODEL GEAR 2015 AND 2016 HAVE SEVERAL ISSUES INCLUDING THIS ONE AS OUTLINED IN SPECIAL COVERAGE N192291660 WHICH EXTENDS THE COVERAGE FOR THIS ISSUE TO 120,000 MILES. IF GMC HAS THE SAME ISSUE WITH THE PREVIOUS YEAR TRANSMISSIONS AND KNOWS ABOUT IT ENOUGH TO ISSUE A SPECIAL COVERAGE, THEY SHOULD DO THE SAME FOR THE 2017 MODELS.

BRAKE LIGHTS INTERMITTENTLY WORK. WILL COME ON SOMETIMES AND THEN GO OUT. THIS HAPPENS WHEN THE CAR IS STILL AND WHILE MOVING.
