2015 GMC YUKON XL Complaints

BRAKE PEDAL IS STIFF AT LOW SPEEDS. THE PEDAL LOCKS UP AND STOPPING IS DELAYED 2 TO 3 FEET. IT MAKES OPERATING THE VEHICLE UNSAFE. I HAVE DONE RESEARCH ON THIS ISSUE. OTHERS ARE EXPERIENCING THE SAME DANGEROUS DELAYED STOPPING DISTANCE AND STIFF BRAKE PEDAL AT LOW SPEEDS.

MY REAR TAIL LIGHT WENT OUT 1 MONTH AFTER WARRANTY ENDED. THIS HAPPENS TO ALL MANY AUTOS IN THIS CLASS. PLEASE DO SOMETHING OR I WILL STOP BUYING GMC AUTOS.

MY PASSENGER BRAKE LIGHT INTERMITTENTLY DOES NOT WORK. THIS IS CLEARLY A COMMON PROBLEM WITH THIS MAKE AND MODEL. HERE IS AN EXAMPLE OF ONE OF MANY FORUMS : HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963 THIS IS A SAFETY PROBLEM AND GMC SHOULD OFFER A RECALL FOR THEIR FAULTY LED LIGHTS.

THIS IS THE SECOND COMPLAINT THAT I HAVE MADE TO NHTSA. THE FIRST TIME, THE VEHICLE WAS SPONTANEOUSLY TURNING OFF AND SHUTTING DOWN DURING BACKING IN AND TURNS CAUSING A SAFETY ISSUE. THIS RESULTED IN A RECALL, AND A "SOFTWARE UPDATE" THAT WAS DONE TWICE TO CORRECT THE ISSUE. RIGHT AND BACK PASSENGER LIGHTS BEGAN TO BLINK ON AND OFF AND WATER GETS INTO THE BRAKE LIGHT. THE DEALER TOLD ME THIS WAS M ISSUE. THIS TIME THE 4WD SERVICE LIGHT CAME AND THE CAR APPEARED TO BE STUCK IN "4WD LOW" MAKING IT "DRAG" AT A REDUCED SPEED WHEN DRIVING. ALSO, THE "SERVICE TRAILER BRAKE" LIGHT CAME ON REPEATEDLY. I HAVE NEVER USED THE TRAILER BRAKE. I TOOK IT INTO AN AUTHORIZED DEALER, SELLERS GMC IN FARMINGTON HILLS, MI. THEY TOLD ME I NEEDED A NEW "MODULE", SO I PAID TO HAVE THAT DONE. WITHIN ONE DAY THE SAME SERVICE LIGHTS CAME ON AGAIN. "SERVICE 4 WD" AND "SERVICE TRAILER BRAKE." I IMMEDIATELY TOOK THE VEHICLE BACK AND AM NOW BEING TOLD IT NEEDS ANOTHER SOFTWARE UPDATE AND A NEW TRAILER BRAKE TRANSFER SWITCH. QUITE FRANKLY, I BELIEVE THAT THIS MODEL HAS SIGNIFICANT, UNADDRESSED COMPUTER SOFTWARE ISSUES AND THE DEALER DOES NOT KNOW WHO TO FIX IT. THE CAR IS UNSAFE BECAUSE IT SPONTANEOUSLY STOPS WORKING APPROPRIATELY DURING DRIVING. THE CONCERNS HAVE BEEN VARIOUS AND ALWAYS SEEM TO AFFECT STEERING, WHEN TURNING OR BACKING IN. I AM BEING CHARGED FOR VARIOUS CONTROL PANELS AND MODULES. I AM REQUESTING THAT THIS CONCERN GETS ADDRESSED BEFORE THERE IS A SERIOUS INJURY. I WOULD LIKE MY VEHICLE FIXED AND RETURNED TO A SAFE CONDITION. I WAS NEVER TOLD UPON PURCHASE, THAT THIS MODEL WOULD REQUIRE SO MANY "SOFTWARE" UPDATES TO REMAIN SAFE. THIS SHOULD NOT BE A BURDEN PLACED ON A CONSUMER FOR A VEHICLE TO OPERATE SAFELY. THIS IS DANGEROUS.

FROM TIME TO TIME BRAKE PEDAL BECOMES HARD WHEN BACKING UP OR GOING FORWARD MAKING THE VEHICLE HARD TO COME INTO A COMPLETE STOP.

I AM EXTREMELY DISAPPOINTED AT GENERAL MOTORS AT THE LACK OF QUALITY DESIGN IN THE REAR TAIL LIGHT LED ASSEMBLY. MY WIFE AND I HAVE OWNED GMC VEHICLES ALL OUR LIVES AND HAVE NEVER BEEN MORE DISSATISFIED WITH THE LACK OF QUALITY DESIGN IN THE REAR TAIL LIGHT LED DESIGN AND DESIGN LIFE. IN CONDUCTING RESEARCH THE LAST FEW DAYS, THIS HAS BEEN A CONSISTENT AND WELL DOCUMENTED DESIGN FLAW THAT GM STILL HAS NOT ADDRESSED. LED LIGHTING WHEN DESIGN PROPERLY IS SUPPOSED TO FUNCTION PROPERLY MUCH LONGER THAN STANDARD BULB INCANDESCENT LIGHTING. THIS CREATES A SAFETY ISSUE WITH OUR VEHICLE BECAUSE WE HAVE NO REAR LIGHTING AND THEN WE RECEIVE THE ESTIMATE FROM OUR DEALER "ROYAL BUICK GMC" AT OVER $1500. OBVIOUSLY, I AM FEELING SUCH FRUSTRATION BECAUSE MY REAR TAIL LIGHT ASSEMBLY'S ARE NOT FUNCTIONING PROPERLY ON MY WIFE'S **** GMC YUKON XL SLT. OF COURSE AFTER THE INITIAL WARRANTY HAS EXPIRED. COINCIDENCE, OR NOT VERY DISPLEASED? I WOULD LIKE SOMEONE CONTACT ME AT ***-***-**** OR BY EMAIL AND OFFER ASSISTANCE TO REPLACE THESE TAIL LIGHT ASSEMBLIES DUE TO THE QUALITY OR LACK THERE OF, IN THE PART. **SINCERELY DISGRUNTLED GM CUSTOMER!!! *TR

THE BRAKE LIGHTS ON MY 2015 GMC YUKON XL HAVE BOTH GONE OUT. I HAVE BEEN PULLED OVER AND QUESTIONED ABOUT IT SEVERAL TIMES BY MY LOCAL LAW ENFORCEMENT. I BELIEVE THE MANUFACTURER STATE THAT THEY HAVE A LIFE OF 40,000 HOURS OF CONTINUOUS USE BUT, ONLY FUNCTION FOR A FRACTION OF THIS AMOUNT & THEY ARE $600-700 TO REPLACE.

WHEN COMING TO A STOP, THE BRAKE PEDAL BECAME STIFF AND DID NOT ENGAGE. THIS HAS HAPPENED ON MULTIPLE OCCASIONS IN THE PAST, AND HAPPENS WHEN THE VEHICLE IS TRAVELING AT SLOW SPEEDS (LESS THAN 5MPH). THE ISSUE IS A FAULTY POWER BREAK PUMP.

TODAY, WHILE COMING TO A STOP, THE BRAKE PEDAL BECAME STIFF AND DID NOT ENGAGE. THIS HAS HAPPENED ON MULTIPLE OCCASIONS IN THE PAST, AND HAPPENS WHEN THE VEHICLE IS TRAVELING AT SLOW SPEEDS (LESS THAN 5MPH).

THERE IS A KNOWN ELECTRICAL ISSUE WITH THE YUKON TAIL LIGHTS. THE ENCLOSED LED RUNNING LIGHTS AND BRAKE LIGHTS WILL GO OUT AND NOT OPERATE. THIS IS A HUGE SAFETY CONCERN AS THERE IS NO BRAKE LIGHT THAT WILL ILLUMINATE AND NO RUNNING LIGHT. BOTH OF MY TAIL LIGHTS HAVE GONE OUT ON MY VEHICLE. DURING A RECORD CHECK I HAVE LEARNED THAT THIS IS A COMMON PROBLEM WITH THE YUKON'S. GMC HAS FAILED TO TAKE ACTION ABOUT THE KNOWN PROBLEM. THE PROBLEM IS PERSISTENT WHILE BEING STOPPED AND DRIVING. SECONDLY THE BRAKING VACUUM SYSTEM WILL GO OUT UNEXPECTEDLY. THIS CAUSES THE ASSISTED BRAKES TO FAIL CAUSING THE BRAKING SYSTEM NOT TO TAKE AFFECT AND STOP THE VEHICLE PROPERLY. THIS IS A HUGE SAFETY CONCERN AS YOU WILL NOT BE ABLE TO SAFELY STOP YOUR VEHICLE IN A TIMELY MANNER AND WILL CAUSE SEVERAL ACCIDENTS. I NOTICED THAT THE BRAKES HAD FILLED WHILE BEING STOPPED AT A STOPLIGHT AND ALSO WHILE BEING MOBILE AND DRIVING.
