2016 GMC YUKON XL Complaints

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.

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.

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.

VERY STRONG SMELL OF A GAS LEAK ON THE DRIVER SIDE OF THE VEHICLE. NO MATTER THE FUEL LEVEL, RUNNING OR STOPPED FOR HOURS.

REAR PASSENGER BRAKE LIGHT STOP WORKING, VEHICLE IS ONLY 2 YEARS OLD. WE SHOULD NOT BE HAVING THIS ISSUE SO SOON OR AT ALL, SINCE LED LIGHTS NORMALLY DONT STOP WORKING. I ALSO LOOKED INTO FIXING IT AND ITS GONNA COST $700 DOLLARS. THIS IS RIDICULOUS!

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. WHILE THE CONTACT'S WIFE WAS DRIVING 65 MPH, WATER LEAKED FROM THE HEADLINER CONSOLE. THE VEHICLE WAS NOT TAKEN TO A DEALER TO BE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 62,000.

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.

PROGRESSIVE INTERMITTENT BRAKE LIGHT FUNCTIONALITY THAT EVENTUALLY CULMINATED WITH COMPLETE INOPERABILITY; ONLY THE RIGHT/LEFT BRAKE LIGHT ASSEMBLIES ARE AFFECTED; REVERSE LAMPS OPERATE; UPPER CENTER BRAKE LIGHT FUNCTIONS NORMALLY; THIS IS A KNOWN PROBLEM WITH GMC BRAKE LIGHT ASSEMBLIES PER MULTIPLE FORUMS

DRIVERSIDE TAIL LIGHT INTERMITTENTLY STOPS WORKING. CAR MILAGE IS IN THE 40,000'S. DIAGNOSTIC TEST AT DEALERSHIP WHERE PURCHASED CONFIRMS " DRIVER REAR TAIL LIGHT SHORTED OUT INTERNALLY. RECOMMEND REPLACING DRIVER TAIL LIGHT. RECOMMEND TAIL LIGHT ASSEMBLY $899" . MY SISTER HAS A YUKON XL DENALI 2016 AND HAS THE SIMILAR ISSUE BUT BOTH OF HER TAIL LIGHTS INTERMITTENTLY STOP WORKING POSING A HUGE SAFETY CONCERN. DRIVING IN MY AREA I SEE MANY NEWER YUKON XL WITH THE DRIVER SIDE TAIL LIGHT OUT. LIGHTING IS NOT COVERED UNDER EXTENDED WARRANTY AND COST TO FIX IS EXTREMELY EXPENSIVE, WHICH COULD MAKE THE AVERAGE DRIVER PUT OFF THE LARGE EXPENSE. THE TAIL LIGHT INTERMITTANTLY STOPS WORKING WHILE THE CAR IS ON, DOES NOT MAKE A DIFFERENCE IF THE CAR IS STATIONARY OR IN MOTION. SERVICE REP AT DEALERSHIP STATED THIS PROBLEM IS "COMMON".

BOTH TAIL LIGHTS AND BRAKE LIGHTS STOPPED FUNCTIONING WITHIN A WEEK OF EACH OTHER. NO BULB TO REPLACE AS THEY ARE LEDS AND ENTIRE HOUSING HAS TO BE REPLACED.
