What 839 owners told NHTSA about the 2015 GMC Yukon Xl 1500

WHILE OPERATING THE VEHICLE AND ATTEMPTING A STOP THE BRAKING BECAME POOR AND I HAD TO DEPRESS THE BRAKE PEDAL AS HARD AS I COULD. HOWEVER, EVEN AFTER THAT THE VEHICLE DID NOT STOP RIGHT AWAY AND TOOK MORE DISTANCE TO COME TO A FULL STOP. THE BRAKE FELT "SOFT" AND NOT LIKE IT USUALLY DOES. INTERESTINGLY...THE BRAKE WOULD SEEM TO WORK AGAIN IMMEDIATELY AFTER THE INCIDENT. I'VE HAD PROBABLY 3 OR 4 INCIDENTS, OVER THE PAST YEAR, WHERE THIS HAS HAPPENED. NONE OF THE INCIDENTS HAVE RESULTED IN ANY TRAFFIC INCIDENTS, BUT ALL HAVE REQUIRED MORE STOPPING DISTANCE THAN NORMAL. ALL OF THE INCIDENTS HAVE TYPICALLY OCCURRED AT LOWER SPEEDS (LESS THAN 40 MPH).

WHEN MOVING IN A PARKING SPOT THE BRAKE PEDAL BECAME HARD AS IF IT LOST POWER BRAKES, BUT THEN RETURNED. A FEW DAYS LATER ON THE FREEWAY TRAFFIC STOPPED IN FRONT OF US AND IT HAPPENED AGAIN. THIS CAUSED US TO NEED TO SWERVE TO AVOID CAUSING AN ACCIDENT UNTIL WE WERE ABLE TO COME TO A STOP. AFTER SEVERAL MILES THE POWER BRAKES HAVE NOT RETURNED. THERE IS OIL IN THE VACUUM LINE AT THE BOOSTER AND GAS MILEAGE YA BEEN POOR THE PAST FEW WEEKS PRIOR TO THIS. IT ALL POINTS TO A FAULTY VACUUM PUMP. 121,000 MILES ON THE TRUCK.

WHEN DRIVING IN STOP AND GO TRAFFIC OR CITY DRIVING THE BRAKE PEDAL WILL BECOME HARD TO PUSH AND LITTLE TO NO BRAKING POWER. BRAKES ARE FINE AT HIGH WAY SPEEDS.

NHTSA ODI 11150701

BRAKE VACUUM PUMP FAILED. WHILE TOWING A BOAT AND BACKING UP MY BRAKE PEDAL WENT HARD WHEN I PUSHED DOWN AND MY VEHICLE WOULD NOT STOP. I WAS ABLE TO STEER OUT OF DANGER AND EVENTUALLY COME TO A STOP.

MY PASSENGER FRONT LIGHT COVER IS ACQUIRING CONDENSATION WHICH MAKES THE LIGHTS GO OFF AND ON, AND MY DRIVER SIDE BRAKE LIGHT WORKS ONLY INTERMITTENTLY. MY INSURANCE OR WARRANTY WON'T COVER ANYTHING TO FIX THESE LIGHT ISSUES. THESE ISSUES STARTED ABOUT MAY 2018. WE WEREN'T IN A WRECK OR SUSTAINED ANY DAMAGES THAT WOULD HAVE LED TO THESE ISSUES. I HAVE TALKED TO TWO OTHER OWNERS OF THE SAME MAKE/MODEL/YEAR VEHICLE AND WE ALL HAVE SAFETY ISSUES THAT ARE NOT BEING RESOLVED BY GM VWARRANTIES. I WANT TO SEE GM ISSUE RECALLS AND ACCEPT COMPLETE FINANCIAL RESPONSIBILITY FOR REPAIRS. I WOULD ALSO LIKE TO SEE THE REAR LIGHTING SYSTEM REDESIGNED SO THE COMPONENTS ARE NOT DEPENDENT ON EACH OTHER. MY BRAKE LIGHT WENT OUT AND INSTEAD OF BEING ABLE TO REPLACE A BULB THE ENTIRE UNIT HAS TO BE REPLACED AT $1700.00 THAT WE JUST SIMPLY DO NOT HAVE.

DRIVING AT A LOW SPEED THROUGH A DRIVE THROUGH AND MY BRAKES FAILED WHEN I TRIED TO STOP BEFORE PULLING OUT ONTO A CROSS STREET. PEDAL LOCKED, AND VEHICLE CONTINUED TO ROLL. AFTER STEPPING ON THE BRAKES A FEW TIMES THEY ENGAGED AGAIN. SAME PROBLEM HAPPENED AGAIN WHEN I WAS LEAVING A PARKING LOT, ONLY THIS TIME THE BRAKES WOULD NOT ENGAGE AFTER SEVERAL ATTEMPTS. I COASTED INTO A POTTED DECORATIVE TREE THAT STOPPED ME, SHIFTED INTO NEUTRAL AND BACK INTO DRIVE AND THEY BEGAN WORKING AGAIN. NO WARNING SIGNALS APPEARED ON DASH, AND BRAKES AND BRAKE FLUID HAVE BEEN CHECKED AND ALL ARE SATISFACTORY.

THE PASSENGER TAIL LIGHT IS WORKING INTERMITTENTLY. THE DEALER SAID THAT THE ONLY FIX IS TO BUY A NEW BRAKE LIGHT UNIT @ $650. AFTER SEARCHING ON LINE, OTHER OPTIONS ARE TO SEND BRAKE LIGHT UNIT OFF FOR REPAIR, OR PURCHASE AFTER MARKET BRAKE LIGHT UNIT. AS MANY PEOPLE THAT ARE HAVING THIS SAME ISSUE, IT SURE SEEMS LIKE GMC WOULD CORRECT THIS FAULTY BRAKE LIGHT.

BRAKE PEDAL SUDDENLY GOT ROCK HARD WHEN I WAS TRYING TO SLOW DOWN, OUR TRUCK JUST KEPT GOING FORWARD, I WAS HELPLESS IN THAT SITUATION AND REALLY THOUGHT THAT ACCIDENT IS UNAVOIDABLE BECAUSE I WAS GETTING CLOSER AND CLOSER TO ANOTHER VEHICLE, AFTER PRESSING BRAKE PEDAL MANY MORE TIMES I WAS ABLE TO STOP OUR YUKON LITERALLY ONE INCH FROM A CAR IN FRONT OF ME

I WAS TOLD MY A COLLEGUE THAT MY DRIVERS SIDE BRAKE LIGHT WAS OUT. I TOOK IT INTO THE LOCAL MECHANIC AND IT WAS NOT OUT. A FEW MONTHS GO BY AND I AM TOLD AGAIN, THAT MY DRIVERS SIDE TAIL LIGHT IS OUT. I TAKE IT TO A DIFFERENT SHOP AND IT IS WORKING CORRECTLY. THE VERY NEXT DAY A TRUCK TELLS ME AT A STOP LIGHT THAT I HAVE NO BRAKE LIGHTS. I WAS PULLED OVER BY A POLICE OFFICER FOR NOT HAVING PROPERLY WORKING BREAK LIGHTS. HE LET'S ME GO WITH A FRIENDLY NOTICE, BUT AS SOON AS I STARTED MY VEHICLE TO DRIVE AWAY HE IMMEDIATELY PULLS ME BACK OVER TO TELL ME THAT HE WAS MISTAKEN THAT ONLY MY DRIERS SIDE BRAKE LIGHT WAS OUT. THIS HAS HAPPENED INTERMITTENTLY OVER THE LAST THREE TO FOUR MONTHS.

MY RIGHT SIDE BRAKE ASSEMBLY SEEMS TO ONLY WORK WHEN IT WANTS TOO. WORKS ON COLD MORNINGS, BUT AS THE DAY GETS WARMER THE LIGHT ASSEMBLY DOESN'T WORK ANYMORE. NO LIGHTS, OR BRAKE LIGHTS.

DRIVER SIDE BRAKE LED LIGHTING IS WORKING INTERMITTENTLY. HAD IT REPLACED UNDER WARRANTY. PASSENGER SIDE BRAKE LED LIGHTING NOW WORKING INTERMITTENTLY, NEW ISSUE. HAVE NOT HAD REPLACED YET DUE TO OUTRAGEOUS COST($700) FOR FIXTURE REPLACEMENT. ONLY 40,000 MILES ON VEHICLE OBVIOUSLY REFLECTS A SERIOUS SAFETY ISSUE TO FINANCIALLY STRAPPED CONSUMERS.

NHTSA ODI 11111684

REAR LEFT AND RIGHT BRAKE LIGHTS STOPPED WORKING WITH NO WARNING WHILE AT A STOP LIGHT IN THE CITY. APPARENTLY SEVERAL GMC YUKON 2015 OWNERS ARE HAVING THE SAME PROBLEM AND IT'S AN ELECTRICAL DEFECT WITH THE TAILLIGHTS IT'S NOT THE BULBS.

NHTSA ODI 11111096

THE PASSENGER SIDE BRAKE LIGHT ON MY 2015 GMC YUKON NO LONGER WORKS. THE COST TO REPLACE IT IS OVER $500. AFTER DOING SOME RESEARCH ON LED LIGHTS I BELIEVE THE BRAKE LIGHT IS FAULTY OR CHEAPLY MADE AND THAT IT SHOULD LAST A LOT LONGER THAN 3 YEARS AND 66,000 MILES.

NHTSA ODI 11105270

BOTH BRAKE LIGHTS FAILED WITHIN WEEKS OF EACH OTHER - AROUND 60K MILES. FAULTY LED CIRCUIT BOARDS. LIGHT ASSEMBLIES ARE NOT REPAIRABLE BY DEALERSHIP. NEW ASSEMBLY OVER $500 EACH. GM TAKES NO RESPONSIBILITY IN RESOLVING THE ISSUE. UNACCEPTABLE! NO MORE GMS FOR MY FAMILY! .. AND THAT INCLUDES CHEVY.

EARLIER THIS YEAR I PURCHASED A 2015 GMC YUKON DENALI. AFTER DRIVING IT A SHORT AMOUNT OF TIME I REALIZED THE BRAKE PEDAL IS LOCATED SIGNIFICANTLY HIGHER THAN THE GAS PEDAL. I'VE COME TO REALIZE THAT THE ~4INCH GAP IS CAUSING A SEVERE SAFETY HAZARD, ESPECIALLY IN EMERGENCY BRAKING SITUATIONS. MY FOOT, ALONG WITH OTHERS IN THE POST LINKED BELOW, OFTEN GETS CAUGHT IN THE LARGE GAP BETWEEN THE GAS AND THE BRAKE, ESPECIALLY WHEN MOVING QUICKLY. THERE HAVE BEEN MANY INSTANCES TO DATE WHERE THE SOLE OF MY SHOES HAS GOTTEN STUCK UNDER THE BRAKE PEDAL, PREVENTING ME FROM STOPPING IN TIME. I'VE NARROWLY AVOIDED AT LEAST 5 ACCIDENTS, BECAUSE OF THIS. FEARING THAT IT IS A MATTER OF TIME BEFORE IT RESULTS IN A COLLISION I REACHED OUT TO GMC TO SEE IF THERE WAS A FIX. THEY RESPONDED AND SAID THAT THE PEDALS ARE WORKING AS DESIGNED AND SAID THERE WAS NOTHING THAT CAN BE DONE. I'M VERY DISAPPOINTED IN THEIR RESPONSE, ESPECIALLY CONSIDERING THE CLEAR SAFETY HAZARD IT CREATES. IT IS A LARGE CAR, REQUIRING MORE BRAKING DISTANCE THAN MOST. ANY IMPEDANCE TO THE PROCESS SHOULD BE TAKEN SERIOUSLY ESPECIALLY IF IT IS A MANUFACTURER DESIGN FLAW SUCH AS THIS. SIMILAR COMPLAINTS HAVE BEEN VOICED IN THIS ONLINE CONSUMER THREAD. ONE OF MANY THAT I FOUND REITERATING THE PROBLEM. HTTP://WWW.TAHOEYUKONFORUM.COM/THREADS/GAS-BRAKE-PEDAL-DISTANCE.67500/

I JUST COMPLETED A CLAIM FOR MY 2015 YUKON DENALI, NHTSA ID #: 10643049 AND READ THAT ALMOST THE SAME EXACT ISSUES ARE GOING ON WITH THE 2015 CHEVY TAHOE MODELS, SEE: NHTSA ID NUMBER: 10638437, 10633519 AND 10631583. WHEN WILL GM SEE THERE IS A PATTERN AND ISSUE A RECALL FOR THIS TRANSMISSION ISSUE? IN ALL CASES THESE RENDER THE CALLS UN-DRIVABLE AND HAVING TO HAVE THEM TOWED. *TR
