What 497 owners told NHTSA about the 2016 GMC Yukon Denali Xl 1500

The fuel injectors have gone out on our vehicle. While driving the vehicle, the check engine began blinking and our vehicle went into limp mode- could feel the engine misfiring and the vehicle was shaking. We had a family of five and two dogs in the vehicle and were lucky to be in cell service. A message popped up on our dash stating “engine power reduced.” The local dealership confirmed it is a fuel injector issue. GMC has a current recall In place, however it only includes certain states.

Left tail light flickers, after reading internet comments learned that tail light board connections are made of very flimsy metal material, they crack with normal vehicle operations. LED lamps are fine but the power connections to the lamps breaks therefore it renders taillights useless. Replacement cost of those lamps are $700-$800 parts alone. On the internet there is some information I’ll attach that pdf

2016 Yukon XL ~ 90,000 miles. This is the second time I get a low speed braking failure when trying to park, followed immediately by a "Brake Assist Malfunction" warning on the dashboard. Both failures have occurred after a long distance travel. The last one being from Detroit to Chicago on 7/30/22. The failure consisted on the SUV not stopping after I had applied the brake pedal at full when backing up for a parallel parking on a street in Chicago. Same happened after I drove forward almost hitting the car in front of me. The SUV continued moving for about a foot on both situations. Before this incident, similar situation happened on a trip from Detroit to Cleveland on March 2022. The SUV continued to move fwd after I had applied the brakes. In this occasion, I was on a ramp down getting into a parking garage. The SUV did not stop for an approximately a foot as well, and again almost hitting the car in front of me.

On our 2016 GMC Yukon Denali we have experienced intermittently working brake lights on our vehicle. We were first informed by a family friend following us that our passenger side was going in and out and now our driver's side brake light is completely out. The turn signal and reverse light still works but no brake light of any indication. No warnings or messages were given it just went completely out. I believe this is a safety hazard to myself and other driver's. It is also against the law to have a break light out. I've read that there was a recall but it was dismissed in 2021 due to faulty break lights. I also read that it was only fixed at no cost for drivers at 72,000 miles and the vehicle couldn't be older than six years.We purchased our vehicle at 73××× . Not everyone can afford the $1600.00 upfront to fix a problem like this. Please reconsider making this a recall as I have been doing my research alot of Gmc Yukon drivers have experienced this. I want my family to be safe.

In my experience of transmission failure with my 16’ GMC YUKON, there was no warning. I had not experienced any issues with the slipping or jerking feel when accelerating or braking as described in the class action law suit. My vehicle had 105k miles, I took it in for regular maintenance including having the transmission flushed as I was told to do so for preventative maintenance. The transmission failed when I was traveling on the interstate with my family and I came upon some traffic so I applied the brake and the whole vehicle bucked and jerked as it shifted into down gear. I was traveling at 30-35 mph in the traffic and the whole time I felt a slipping motion in the car. I made it to a gas station, refueled, and tried to restart my journey. As I leery the gas station accelerating to get back on the interstate, the vehicle would not accelerate above 35 mph and the RPMs we’re to the max. At this point, my vehicle was in drivable. No prior warning, no issues that had been occurring over time, this all happened the same day. I towed my vehicle to a Chevrolet dealer where the problem was identified as a failed transmission in need of replacement and failed ABS braking system. The cost came at $6800.

2016 GMC Yukon. I received a letter that stated my Yukon may have a condition where the brake lights intermittently do not illuminate. In March 2020 the drivers side rear brake light did not illuminate. I brought it to a Chev/GMC dealer that replaced the tail light no charge. Now my passenger rear tail brake light does not illuminate. My Yukon has 68800 miles on it and it is going on 6 years old. I still have my letter I received about this issue. Without my tail/brake light it is unsafe to drive my vehicle until I get that brake unit replaced. Will I still be able to my passenger side brake unit replaced at no charge? I haven’t been able to get it replaced due to I had total knee replacement surgery in February 2022

The suv starts to brake on its own while driving. It came to a complete stop once and almost caused an accident.

My issue pertains to a known problem. The driver's side tail light has failed. GM issued Special Coverage Adjustment N182180270 because of this issue where the part was covered for up to 6 years or 72k miles. Mine failed after 6 years and 4 or 5 months at 66k miles. It's utterly ridiculous that a defective, $800 light is fine to break after 6 years with no warranty assistance.

The driver’s side brake light assembly failure of no brake light when brake is applied. It can be inspected upon request. This may cause another driver to not notice intentions to stop or slowdown and cause an accident. This problem is constant. It has not been inspected. No warnings of the failure has been displayed.

The drivers side rear brake lights stopped working. GM did a warranty extension ( that admits an issue).but ours just expired.. this is an $800 to $1000 repair that owners should NOT have to pay.. GM refuses to cover this expense. This is an absolute SAFTEY ISSUE. Of course, any law enforcement officer will agree as they will write a safety violation ticket (as they should) I understand that owners are responsible for all maintenance of their vehicles, but this issue is a flaw in design. Most owners ( like us) can’t afford to pay this outrageous price for a simple break light replacement. As the entity of government that oversees the manufacture of these vehicles, there MUST be a safety recall!! Honestly, I am disappointed that no safety recall hasn’t been ordered for this issue. This problem is going to result in many many rear end accidents. Please fix this and save lives.

Last month the passenger tail light stopped working. We took it out not realizing that you have to replace the entire unit. So we put the tail light back in and it magically started working again. Then yesterday the driver's side tail light stopped working, so we did the same. Took it out, waited and put it back (since we know we can't just run to the store and get a new one), except this time it didn't start working. I know there's a recall on the tail lights but I can't seem to find anyone to help me. The vehicle is only 6 years old and the tail lights at $800 each, should last a lot longer than that!
