2016 GMC YUKON XL Service Brakes Problems

I have repair the trailer brake system warning light prior. Now again this faulty wiring module is constantly dinging and flashing warning messages while driving. It's very distracting and irrelevant considering I not towing anything. It covers the speedometer and is a complete nuisance.

Driving back from Las Vegas for a family trip, traffic was heavy, a lot of stop-and go. I started to feel the brakes delay to stop. After a few minutes I was able to pick up a little speed and again traffic was built up. This time the brakes failed and got stiff. I had to slam on the brakes and practically stand up on the brakes in order for the car to stop. I barely avoided wrecking into the car in front of me. I was a few hours away from home and had to drive all the way with this problem. When I got home I took it in to the nearest dealer shop to get the brakes checked . I looked online and found out about the recall on the brakes.

I was driving and n the freeway around 70 miles and " TRAILER Brake SERVICE" message appears on the dash board screen We don't pulling nothing on that time and normally we don't use this car for pulling, the other message appears several times is very frustrating. I am the guy in charge for this vehicle.

Truck keeps saying to service trailer braking system and won't start.

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.

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

THE ENGINE MOUNTED MECHANICAL VACUUM PUMP OUTPUT MAY DECREASE OVER TIME DECREASING THE AMOUNT OF VACUUM/ POWER BRAKE ASSIST. AND THE DRIVERSIDE BRAKE STOP LIGHT WAS DEFECTIVE. .ME AND MY WIFE WERE SCARED AND SHOOK UP. .YES. DEALERSHIP. .DEALERSHIP. NO. .

The brake light LED panel stopped working on one side and goes out intermittently in the other side

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.

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.

DUE TO QUARANTINE I WAS NOT DRIVING OR GOING PLACES BUT ONCE OUR STATE RE-OPENED I CALLED THIS DEALERSHIP TO REPORT THE BRAKE CONCERN AND SCHEDULED APPT. A DAY BEFORE APPT, WHILE STOPPED AT A RED LIGHT AS I MOVED FORWARD IN A VERY SLOW CRAWL MY BRAKES FAILED ME AND I COULD NOT STOP. I BUMPED THE CAR IN FRONT OF ME WHICH RESULTED IN DAMAGE TO BOTH VEHICLES. I REPORTED THIS TO MCGRATH AS I WAS SCARED IMMENSELY ABOUT THE SAFETY OF MY VEHICLE.

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.

BREAK PEDAL GETS HARD AT THE TIME TRADE TO STOP THE VEHICLE

MY WIFE WAS DRIVING DOWN A MAJOR ROAD AND A PERSON PULLED NEXT TO HER AT A STOP TO TELL HER THAT HER BRAKE LIGHTS WERE WORKING ONLY PART OF THE TIME. GM HAD JUST SERVICED MY VEHICLE AND DIDN'T CATCH IT, AND UPON RESEARCHING THE ISSUE, IT IS A KNOWN FAULTY DESIGN OF THE TAIL LIGHT ASSEMBLY. THE LED BRAKE LIGHT STARTS INTERMITTENTLY FAILING AT THE 2 YEAR POINT, LEADING TO DRIVERS FOLLOWING DRIVERS TO NOT KNOW THAT THE LEADING VEHICLE IS STOPPING. THIS IS A COMMON ISSUE AND THE ONLY RESPONSE FROM GM IS TO MAKE THE CUSTOMER BUY A NEW $700 BRAKE LIGHT ASSEMBLY. THE ISSUE IS SO COMMON THAT MULTIPLE COMPANIES HAVE STARTED BRAKE LIGHT REPAIR SERVICES AND MULTIPLE YOUTUBE VIDEOS EXIST TO WALK INDIVIDUALS THROUGH THE PROCESS OF REPAIRING THEIR OWN BRAKE LIGHTS. THE COST OF THE REPAIR IS SO STEEP THAT I HESITATE TO GET THE PROBLEM FIXED, AND THOUGH GM REPORTEDLY HAS DEVELOPED A REPLACEMENT LIGHT ASSEMBLY THAT CORRECTS THE FAULT, THEY ARE NOT TAKING RESPONSIBILITY FOR THE DEFECTIVE BRAKE LIGHT ASSEMBLE THAT THESE VEHICLES COME OFF THE ASSEMBLY LINE WITH. THE MAJOR DANGER IS THAT WE DRIVE FROM THE FRONT OF THE VEHICLE AND LIKELY DO NOT KNOW OUR BRAKE LIGHTS ARE INTERMITTENTLY FAILING--SINCE GM CANNOT EVEN CATCH THIS WHEN THEY DO SERVICE ON VEHICLES (MINE HAD BEEN IN THE SHOP FOR AN OIL CHANGE A FEW WEEKS BEFORE THE BRAKE ISSUE), THEN THEY ARE LEAVING A LOT OF CUSTOMERS DRIVING WITHOUT BRAKE LIGHTS TO AVOID THE COST OF THE REPAIR EVEN THOUGH THEY APPROVED A FAULTY DESIGN.

OVER THE LAST SEVERAL YEARS, WE HAVE BEEN HEARING THIS CLICKING SOUND IN OUR 2016 GMC YUKON XL. ADDITIONALLY, WE HAD EXPERIENCED OCCASIONAL TIMES WHERE THE VEHICLES BRAKES WOULD NOT FUNCTION PROPERLY MOSTLY IN SLOWER SPEED SITUATIONS. IN THE LAST SEVERAL WEEKS, THE SHORT RANGE BRAKING WAS HINDERED AGAIN AS THE BREAK WOULD 'STICK' AND NOT SLOW THE CAR. SEVERAL CLOSE INSTANCES OF HITTING EITHER ANOTHER CAR OR FAMILY MEMBER. I THEN LOOKED UP ON NHTSA IF ANY RECALLS, AND I NOTICED A RECALL WHICH DESCRIBED EXACTLY WHAT WE HAD BEEN EXPERIENCING. WE TOOK THE VEHICLE INTO THE DEALERSHIP YESTERDAY AND THEY TOLD MY WIFE IT WAS FIXED AND SENT HER ON HER WAY TO PICK UP MY 5 CHILDREN FROM SCHOOL. A FEW HOURS LATER, THE CAR JUST WOULDN'T BREAK AND MY WIFE CALLED ME TO ACTUALLY GO TO THE LOCATION ON MY CHILD'S PRACTICE SO I COULD DRIVE IT HOME AS SHE DIDN'T TRUST THE VEHICLE ANY LONGER. I TOOK THE VEHICLE BACK TO THE DEALER THE NEXT DAY. UPON THEIR INSPECTION, THEY SAID THE VACUUM PUMP WAS FAULTY AND WOULD COST $500 TO FIX. THEN I STARTED TO INVESTIGATE FURTHER, AND TO MY SURPRISE, THERE APPEARS TO BE A LONG STANDING ISSUE WITH 2014-16 GM VEHICLES THAT HAVE HAD FAULTY VACUUM PUMPS. HOWEVER, THESE HAVEN'T BEEN RECALLED YET. THE REVIEW ALSO LED ME TO THE CONCLUSION THAT THE CLICKING SOUND WE WOULD HEAR APPEARS TO BE RELATED TO THIS FAULTY PART. UNFORTUNATELY FOR ME, MY MILES ARE BEYOND THE WARRANTY PERIOD BUT THIS HAS BEEN A PERSISTENT ISSUE FOR A LONG TIME. BASICALLY, IT FEELS AS IF MY FAMILY'S SAFETY WAS SECONDARY WHILE THIS KNOWN ISSUE WITH THE VACUUM PUMP REMAINED 'SILENT'. WE BOUGHT THIS VEHICLE FOR THE SAFETY, DEPENDABILITY, AND PLANNED TO USE IT UP TO 200,000+ MILES. I AM DISAPPOINTED THAT A SAFETY ISSUE LIKE THE BRAKES WOULD EFFECTIVELY BE UNDISCLOSED TO ME AS A CAR OWNER. I AM HOPEFUL GM WILL DO ALL THAT IS NECESSARY TO RECTIFY OUR DISCOMFORT AND LACK OF TRUST.

LED BRAKE LIGHTS FAILED AND CANNOT BE REPAIRED. I CANNOT REPLACE BULBS EITHER. GMC WANTS $600+ TO REPLACE THE LIGHT WITH ONE THAT HAS RISK OF FAILURE, SAME AS THE ORIGINAL! NO GUARANTEE!

I HAD THE RECALL (N192268490) APPLIED TO MY YUKON ON 12 SEP. I ONLY EXPERIENCED THE PROBLEM DESCRIBED IN THE RECALL 2X PRIOR TO THE RECALL. SINCE THE RECALL I HAVE HAD MULTIPLE INCIDENTS MUCH WORSE THAN THAN THE ORIGINAL PROBLEM. TONIGHT THE BRAKES WERE SO BAD I OVER SHOT MY PARKING SPOT AND DROVE INTO SOME BUSHES. IF A HARD STRUCTURE WAS THERE I WOULD HAVE DAMAGED THE CAR. THIS PROBLEM IS REPEATABLE. NO WARNING LIGHTS COME ON BUT THE "GRADE BREAKING ON" LIGHT WILL COME ON. THE BREAK PEDAL WAS VERY SOFT AND SHUTTERED. I EMPHASIZE THIS IS NEW SINCE THE RECALL WAS IMPLEMENTED.

A CAR BRAKED IN FRONT OF ME GOING AROUND 40 MILES PER HOUR. I WAS UNABLE TO STOP IN TIME AND REARENDED THEM. THIS CAR IS PART OF THE GM RECALL FOR BRAKES

ATTEMPTED TO SLOW DOWN BY STEPPING ON BRAKES BUT THE PEDAL WAS EXTREMELY STIFF AND THERE WAS NO STOPPING ACTION. HAD TO ALMOST STAND ON THE BRAKE PEDAL WITH ALL MY FORCE TO GET THE VEHICLE TO STOP BEFORE ALMOST HITTING THE VEHICLE IN FRONT. WE HAD THE VEHICLE TOWED TO A DEALER AND THEY SAID THE BRAKE BOOSTER PUMP HAD FAILED AND NEEDED REPLACEMENT

Mileage: 41,000

THE RIGHT REAR TAIL LIGHT BRAKE LIGHTS HAVE GONE COMPLETELY OUT. THESE ARE ONE SOLID HOUSING AND HAVE TO BE REPLACED TO SIMPLY FIX THE BRAKE LIGHT. REVERSE AND TURN SIGNAL LIGHTS ARE OK. THE HOUSINGS COST 600-700 DOLLARS EACH TO REPLACE WHICH IS A LUDICROUS AMOUNT TO HAVE TO SPEND. IN ORDER TO BE WITHIN REGULATIONS FOR INSPECTION, THESE HAVE TO BE WORKING. WE FEEL THERE SHOULD BE A RECALL AS THERE ARE LOTS OF COMPLAINTS ONLINE ABOUT THESE HOUSINGS.

Mileage: 92,000

BRAKES DO NOT WORK AT LOW SPEEDS. GMC TOLD ME THAT THE PARTS HAD BEEN BOUGHT BACK BY GM AND THERE WAS NO WAY TO FIX IT 8 MONTHS AGO AND NOW THEY STATE THERE IS A SPECIAL WARRANTY ADDED EXCEPT MY MILEAGE IS OVER THE WARRANTY! BRAKES EITHER ARE HARD AS A BRICK TO PUSH OR/AND DON'T WORK AT ALL. I WAS TOLD TO REV THE ENGINE WHEN GOING SLOW OR BACKING UP IN ORDER TO MAKE THE BRAKES FUNCTION PROPERLY. THAT WAS THE ADVICE FOR A MOTHER OF 4 CHILDREN. AC IS ALSO BLOWING HOT AIR.

MY 2016 GMC YUKON XL RECENTLY BEGAN HAVING A HARD BRAKE PEDAL WHEN REVERSING OUT OF PARKING SPOTS, OR WHEN ROLLING DOWNHILL. A COUPLE OF TIMES, WHEN ROLLING FORWARD DOWNHILL IT MALFUNCTIONED CAUSING ME TO RUN INTO A DITCH. . THE HARD BRAKE PEDAL HAD CAUSED ME TO NOT BE ABLE TO STOP THE VEHICLE SEVERAL TIMES. IT WOULD ROLL BACKWARDS (OR FORWARDS) UNTIL I SHIFTED IT IN TO GEAR OR GAVE IT GAS. A FEW TIMES I ALMOST HIT VEHICLES AND PEDESTRIANS IN MY SON'S SCHOOL CARPOOL LANE. THERE IS NO WARNING. NO CHECK ENGINE LIGHT. JUST THE HORRIBLE ROCK HARD BRAKE PEDAL WHICH TURNS OUT TO BE A FAULTY VACUUM PUMP PER NAPA JIMMY VASSER CHEVROLET, THAT HAS NOW COST ME $711.00 BECAUSE IT IS NOT COVERED UNDER WARRANTY. MY CAR HAS 54,000 MILES ON IT. THIS IS UNACCEPTABLE.

Mileage: 54,000

BRAKES GET VERY HARD TO PUSH AND DO NOT WORK WELL WHEN GOING SLOW SPEEDS OR BACKING UP. UNABLE TO EVEN FIX AS I HAVE BEEN TOLD THE PART IS ON NATIONAL BACK ORDER! SO I'M STUCK TRYING NOT TO CRASH WITH FAULTY VACUUM BRAKE PART! LEFT REAR SEAT MOTOR WORKS, BUT SMALL PLASTIC PART BROKE SO SEAT WORN MOVE AND IS STUCK IN ONE POSITION.

Mileage: 92,000

THE VEHICLE HAS EXPERIENCED AT SLOW SPEED OR BACKING A SOLID/STUCK BRAKE PEDAL THAT WOULDN'T MOVE. THE PEDAL WAS BASICALLY STUCK, NOT MOVING AT ALL. THIS OCCURRED COMING TO A STOP AT LIKE AN INTERSECTION OR AS STATED BACKING OUT OF A PARKING SPOT. IT FELT AS IF THE TRUCK WOULDN'T STOP AND NO MATTER HOW HARD THE PEDAL WAS PUSHED IT WOULDN'T MOVE FOR A FEW SECONDS.

BEGINNING AROUND 70K MILES, MY WIFE COMPLAINED OF BRAKES NOT WORKING AT LOW SPEED IN PARKING LOTS, ESPECIALLY IN REVERSE, WITH VERY HARD PEDAL, OCCASIONAL OCCURRING. WHILE I WAS DRIVING, OCCURRED MULTIPLE TIMES AT GAS STATION AT VERY LOW SPEED DURING STOP OVER ON A LONG ROAD TRIP AT 80K MILES. UPON TAKING TO GM DEALERSHIP FOR ANOTHER ISSUE, GM SERVICE TECHNICIAN VERIFIED THE CONCERN. VACUUM PUMP REPLACED ON 12/14/18. FEW MILES SINCE BUT TEST DRIVING HAS NOT HAD ANOTHER OCCURRENCE. VEHICLE FAILURE CONFIRMATION AND REPAIR DONE AT JOE BOWMAN CHEVROLET IN HARRISONBURG, VA.

Mileage: 70,000

LOW SPEED BRAKE FAILURE: AT LOW SPEEDS THE BRAKE PEDAL BECAME FIRM AND THE VEHICLE DID NOT STOP IN AN APPROPRIATE TIME. THIS LED TO TWO NEAR ACCIDENTS. BOTH TIMES THE VEHICLE WAS IN A LINE OF CARS THAT WAS STOP AND GO PICKING UP CHILDREN AT AFTER SCHOOL. SERIOUS CONCERN THAT THE VEHICLE WILL NOT STOP AND INJURE CHILDREN TRYING TO LOAD OR UNLOAD. THE PROBLEM APPEARS TO OCCUR ONLY AT LOW SPEEDS ONLY.

Mileage: 75,000

DRIVING AT LOW SPEEDS (5 MPH OR BELOW) THE BRAKES FAILED TO ENGAGE. THE BRAKE PEDAL WAS STIFF AND OFFERED LITTLE PRESS. PRESSING THE PEDAL EXTREMELY HARD BROUGHT THE VEHICLE TO A STOP. THIS HAPPENED MULTIPLE TIMES IN A SINGLE DAY, ALMOST CAUSING AN ACCIDENT IN TRAFFIC AND DID CAUSE ME TO BUMP INTO OUR GARAGE WALL. WHEN A I TOOK THE VEHICLE IN TO BE SERVICED, THE VACUUM PUMP HAD TO BE REPLACED. OUR VEHICLE AS 39,800 MILES. THIS APPEARS TO BE A KNOWN DEFECT: TECHNICAL BULLETIN PIT5361B EXISTS A CLASS ACTION LAWSUIT HAS RECENTLY BEEN FILED (HTTPS://WWW.CARCOMPLAINTS.COM/NEWS/2018/GM-BRAKE-VACUUM-PUMP-FAILURES-LAWSUIT.SHTML) A QUICK INTERNET SEARCH REVEALS MULTIPLE SIMILAR ISSUES. COST TO REPAIR IS OVER $900 AT GMC DEALER.

Mileage: 39,000

ON 9/25/18 WHILE APPLYING BRAKES THE BRAKE PEDAL BECAME EXTREMELY HARD TO PRESS AND VERY HARD TO STOP THE VEHICLE. THANK GOD IT WAS IN MY DRIVEWAY THIS OCCURRED. MY SIGNIFICANT OTHER CAME HOME FROM WORK ON 9/27/18 AND CHANGED PADS, LUBED CALIPER SLIDERS, AND VERIFIED PROPER CALIPER OPERATION. SPENT 9/26/18 TALKING WITH THE DEALER AND CHECKING RECALLS. ALL THESE REPAIRS WERE SUGGESTED BY THE LOCAL DEALER, BY THEM OF COURSE. UPON TEST DRIVE AFTER NEW PADS WERE INSTALLED, THE SAME ISSUE HAPPENED. DRIVING FORWARD THE BRAKES OPERATE AS THEY SHOULD OR AT LEAST FEEL NORMAL.

Mileage: 63,756

WHEN STARTING AND STOPPING (DEPRESSING THE BRAKE PEDAL MULTIPLE TIMES) SUCH AS AT A LEFT TURN (WAITING FOR TRAFFIC) OR A DRIVE-THRU WINDOW, THE BRAKES STOP WORKING AND THE CAR ROLLS FORWARD EVEN WHEN THE BRAKE IS DEPRESSED. IF YOU PRESS REALLY HARD IT WILL USUALLY STOP- BUT IT DEFINITELY ROLLS FORWARD WHEN YOU ARE TRYING TO STOP. THE DEALERSHIP SAYS THAT A VACUUM PUMP IS FAULTY BUT THIS COULD RESULT IN AN ACCIDENT AS I ALMOST ROLLED INTO ONCOMING TRAFFIC WHILE WAITING IN LINE TO TURN LEFT AT A "LEFT TURN YIELD ON GREEN LIGHT".
