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

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 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.

Both brake lamp assemblies are non-op, no warning in dash and no fuses. GMC #SCA N182180270 stating that 2015 and 2016 Yukon. Extended warranty to 6 years or 72,000 miles. We are out of warranty as of last month. $2,500 to replace the tail lamp assemblies. No letter was sent to owners regarding this safety hazard. This should be a RECALL

I was driving with a trailer that has brakes. A warning system light came on “trailer brake system” service came on blind the digital speedometer. Brakes would not engage. A couple of day later same thin came on now with out a trailer. The warning would not go away and kept on chumming every 10 seconds.

The trailer break service light is coming on. There is not a way to dismiss the sound and comes on every few seconds, it's very distracting a HUGE safety risk. I have contacted GMC Valencia California and they have have several vehicles with the same issue / hazard. This has apparently been going on for years yet GMC refuses to put a recall on the vehicles nor take action on correcting this on this critical issue. This is very upsetting and with all the complaints / concerns it appears nobody cares for the lives this defective issue could cause, especially when towing. Thank you.

The contact owns a 2016 GMC Yukon. The contact stated that while driving at approximately 70 mph, the brake pedal was hard to depress and the brake pedal traveled to the floorboard. The contact mentioned that the brake pedal needed to be pumped in order for the vehicle to be operated. In addition, the contact stated the vehicle failed to stop immediately. The vehicle was taken to a dealer where it was diagnosed that the brake line needed to be flushed. The vehicle was repaired however, the failure persisted. The vehicle was taken to an independent mechanic where the failure was undetermined. The contact mentioned while the mechanic was reversing the vehicle the brakes failed to operate causing the vehicle to crash into a person and a vehicle. The contact stated that the lady sustained multiple injuries that needed medical attention. A police report was filed. The vehicle was towed to the dealer where it was diagnosed that the brake vacuum pump needed to be replaced. The vehicle was repaired but the failure recurred. The vehicle was taken back to the same dealer where they informed the contact that the failure was unable to be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage 54,000.

Rear driver taillight assembly does not work all the time! One day it works the next day it does not! I had to have the passenger side replaced about 6-8 months ago & it was replaced by the dealer at that time & there was no cost to me as it was under warranty at that time! I think there may be an issue with the LED bulbs! Now the problem is with the drivers side! This is a safety problem and a recall should be issued!!!!It is no longer under warranty & out of pocket cost may be $600 to $1000!

Vacuum pump loses vacuum, and the brakes are very hard. Occurs when sitting still with the brake applied. Also occurs in reverse at low speeds. My wife refuses to drive her car, due to numerous near fender benders.

I SEE ALMOST 200 COMPLAINTS AND NOTHING HAS BEEN DONE? NOT SURE THE POINT OF THIS WEBSITE, BUT, I'M GOING TO PUT MY 2 CENTS IN. MY 2016 YUKON DENALI PASSANGER BRAKE LIGHT HAS GONE OUT, LIKE MANY, MANY OF OTHER PEOPLE. WHY ISN'T THIS A RECALL? OBVIOUSLY, THERE IS A MANUFACTURING ISSUE THAT NEEDS TO BE ADDRESSED. AFTER MANY VIDEOS I HAVE WATCHED I SEE THAT THE CIRCIT BOARD COMES APART AND CAN'T BE REPAIRED BUT ONLY REPLACED, AT A EXTREMLY HIGH PRICE. I'VE ALSO SEEN MANY TAIL LIGHT ON THESE YUKONS WORK OFF AND ON, SO, RANDOMLY THEY CAN NOT WORK AT ANY TIME AND POSSIBLY GET YOU REAR ENDED. HOW DO I FILE A CIVIL ACTION COMPLAINT TO HAVE GMC ADDRESS THIS COMPLAINT AND RESOLVE THIS ISSUE? PLEASE ADVISE.

THE SERVICE BRAKE ASSIST MESSAGE APPEARS AND THE BRAKING AT SLOW SPEEDS IS VERY UNRESPONSIVE. TO STOP YOU MUST FULLY PRESS THE BRAKE AND THE BRAKES SEEM NOT TO GRAB. TAKES LONGER DISTANCE TO STOP. THIS IS VERY INTERMITTENT, ONE TIME THEY WORK AND THE NEXT TIME YOU CAN'T STOP UNLESS YOU PUT YOUR FOOT THROUGH THE FLOOR ON THE BRAKE.

ON TWO OCCASIONS WHILE IN A DRIVE THRU LINE, I WOULD PRESS THE BRAKES AND THE BRAKE PEDAL WOULD GO TO THE FLOOR. I HAD TO BASICALLY STAND UP ON THE BRAKE PEDAL TO GET THE VEHICLE TO STOP. I HAVE NOT HAD THIS HAPPEN OTHER THAN AT A LOW RATE OF SPEED. I SEARCHED GMC YUKON FOR ANY RECALLS AND FOUND THAT THIS IS A RECALL WITH GMC. WHEN YOU DO A SEARCH OF MY VEHICLE BY VIN, IT STATES NO RECALLS ARE FOUND. I CONTACTED A LOCAL GMC DEALER AND WAS TOLD THAT THEY CAN'T DO ANYTHING UNLESS MY VIN SHOWS THE ACTIVE RECALL.

ONE BRAKE LIGHT WAS INTERMITTENT, NOW BOTH WON'T WORK AT ALL. DOING AN INTERNET SEARCH, MANY, MANY PEOPLE COMPLAIN ABOUT THIS PROBLEM. THE BULB CANNOT BE REPLACED. DEALERS CHARGE $500+ FOR EACH TAIL LIGHT ASSEMBLY AND WILL NOT TAKE RESPONSIBILITY. THIS IS DANGEROUS FOR BRAKE LIGHTS TO NOT WORK.

MY BRAKE LIGHTS WILL WORK ONE MINUTE AND GO OUT THE NEXT. I HAD A FRIEND AND MY HUSBAND TELL ME THAT WHEN THEY WERE FOLLOWING ME THE LIGHT WAS OUT WHEN I STOPPED BUT AT THE NEXT STOP OR AT HOME IT WOULD WORK. THIS HAS BEEN HAPPENING FOR MONTHS. LAST WEEK I TOOK IT FOR STATE INSPECTION AND THE INSPECTOR SAID IT WAS OUT I HAD TO GET IT REPLACED. WHEN I PULLED FORWARD IT STARTED WORKING AGAIN TO PASS INSPECTION. TODAY I TOOK MY YUKON TO THE DEALERSHIP FOR AN OIL CHANGE AND IT WENT OUT AGAIN. OTHERS WAITING TOLD ME THIS IS A RECALL ON OTHER YEAR/MODELS WITH GMC. THERE IS A SHORT IN THE CIRCUIT PANEL.

I PURCHASED MY TRUCK FROM GILROY CHEVROLET IN SEPTEMBER 2019. THE WEEK WE BOUGHT IT MY HUSBAND HAD TO CHANGE THE BREAKS AS THEY NEEDED TO BE CHANGED. SHORTLY AFTER WITHIN A WEEK FROM THAT WE STARTED HEARING A POPPING SOUND FROM THE LEFT FRONT PART OF THE TRUCK. SOMEWHERE NEAR THE AXEL OR TIRE BARING. I CONTACTED THE DEALER AND STATED THEY HAD SOLD ME A CAR WITH NO BREAKS AND WITH THIS MYSTERIOUS NOISE. THEY DIAGNOSED THE CAR, CHARGED ME AND DIDN'T FIX THE PROBLEM I DIDN'T EVEN GET REIMBURSED OR AN APOLOGY FOR BEING SOLD A CAR THAT HAD NO BREAKS. I HAVE TAKEN MY CAR TO A NEW DEALER FOR FURTHER DIAGNOSIS. WHERE THEY ARE ASKING ME TO PAY FOR A DIAGNOSTIC FEE AND DEDUCTIBLE I FEEL THE ORIGINAL DEALER WHO SOLD ME THIS DEFECTIVE CAR SHOULD HAVE TO PAY SINCE I HAVE PAID THESE DUE ONCE ALREADY. ANY TIME THE STEERING WHEEL IS TURNED ALL THE WAY YOU FEEL AND HEAR THE POPPING NOISE.
