WAS DRIVING ABOUT 7-10 MPH IN A WAL MART PARKING LOT WHEN THE STEERING ON MY 2015 GMC YUKON DENALI COMPLETELY GAVE OUT WHICH CAUSED ME TO SCRAP A POLE ON THE BACK DOOR BEHIND DRIVER. FINALLY WHEN VEHICLE CAME TO A COMPLETE STOP THE STEERING WHEEL WOULD FREELY SPIN AND NOT IN GAUGE THE TIRES TO ROTATE. HAD THE VEHICLE TOWED TO THE NEAREST GMC DEAR SHIP TO HAVE THEM ASSES THE PROBLEM AND TOLD THEM THIS HAS TO BE FROM THE ROOT CAUSE OF A RECALL THAT A SENSOR WILL LOSE TEMP CONNECTION WITH STEERING AND MAY CAUSE AN ACCIDENT. WHICH DID AS WELL AS INJURY TO MY WIFE WHO WAS DRIVING. NOW THE VEHICLE IS AT THE GMC DEALERSHIP GIVING ME A RUN A ROUND THAT THE STEERING COLUMN MAGICALLY SNAPPED AND NEEDS TO BE COVERED THROUGH EXTENDED WARRANTY. I HAVE AN OPEN COMPLAINT WITH THE DEALERSHIP AS WELL AS GMC IT SELF. PLEASE IF YOU OWN THIS YEAR VEHICLE BE VERY CAREFUL THIS COULD HAVE BEEN A REALLY HORRIBLE SITUATION.

DRIVERS AND PASSENGER BRAKE LIGHT GO OUT INTERMITTENTLY. PASSENGER STAYS OFF FOR LONG PERIODS OF TIME. LOOKED INTO REPLACING NO IDEA IF IT WILL FIX THE PROBLEM. COST AT LEAST $500. EACH PARTS ONLY. I HAVE SEEN SO MANY OTHER VEHICLES LIKE MINE SAME PROBLEM. HEADLIGHTS ALSO GOING OUT, WATER INSIDE OF COVER. LED AND TURN SIGNAL WENT OUT ON DRIVERS SIDE REPLACED FOR A COST OF $900.00, (JUST FOR THE HEADLIGHT) AGAIN NO GUARANTEE IT WILL KEEP WORKING. ALSO BATTERY WENT DEAD REPLACED BATTERY. NEW BATTERY ALSO WENT DEAD. CAR ALARM WENT OFF THE NIGHT BEFORE BATTERY DEAD IN THE MORNING. HAS BEEN IN THE SHOP 3 WEEKS NOW. SAME THING HAPPENS ALARM GOES OFF KILLS BATTERY. SHOWS MASSIVE DRAIN AND SET ABOUT 32 CODES. THE DRAIN DOESN'T REGISTER AFTER THAT. RECHARGE BATTERY CAR IS NOT RUNNING WHEN THIS HAPPENS. PROBLEM REPEATS EVERY TIME AFTER CHARGING THE BATTERY. SOMETHING IN THE WIRING IS SHORTING OUT. TESTED BOTH BATTERIES THEY BOTH TEST GOOD. AFRAID OF WHAT WILL HAPPEN NEXT WITH THE ELECTRICAL ON THE VEHICLE. NOT SURE IF THE LIGHTS HAVE ANYTHING TO DO WITH THIS OR NOT. WHEN ORDERING HEADLIGHT AND ASKING ABOUT BRAKES TOLD BY DEALER PARTS THEY SURE ARE SELLING A BUNCH OF THESE. I HAVE HAD PEOPLE DRIVING DOWN THE ROAD STOP ME TO TELL ME MY BRAKE LIGHT IS OUT. I DID NOT KNOW THAT THE TURN SIGNAL ON THE FRONT WAS NOT WORKING UNTIL A CAR PULLED OUT IN FRONT OF ME WHILE WAITING TO MAKE A LEFT TURN. I GOT OUT AND LOOKED AT THE LIGHT AND IT WAS NOT WORKING. I CANNOT DRIVE THE VEHICLE AT ALL BECAUSE IT KEEPS DRAINING THE BATTERY. I HAVE A ASE CERTIFIED MASTER TECHNICIAN WORKING ON THE VEHICLE IN A REPUTABLE SHOP.

2015 GMC YUKON DENALI, BREAK LIGHT MALFUNCTION, DRIVING, PARKED WITH NO INDICATION WHEN IT WILL WORK OR NOT. DEALERSHIP AND GMC SERVICE CENTER CLAIMED THERE WERE NO OR VERY FEW COMPLAINTS HOWEVER I HAVE FOUND HUNDREDS ALREADY. THEY REFUSED TO EVEN LOOK AT THE LIGHT STATING I CAN GET IT REPLACED FOR AROUND $775 BECAUSE THEY CANNOT CHANGE BULBS ON THAT TYPE OF TAIL LIGHT. DEALERSHIP TOLD ME THAT THIS WAS NEW FEATURE STARTING WITH MY YEAR MODEL AND SINCE GMC WENT WITH ENCASED LED LIGHTS THEY NO LONGER CAN FIX THEM UNDER WARRANTY. THIS WAS NEVER DISCLOSED ANYWHERE AND GMC DOES NOT STATE THAT ANYWHERE I COULD FIND AND WILL NOT COVER IT UNDER FACTORY WARRANTY EVEN THOUGH IT IS OBVIOUSLY A WIRING ISSUE SINCE THE LIGHT DOES WORK SOMETIMES. I ALSO HAD PROOF WITH PICTURES THAT THE TAIL LIGHT DOES WORK SOMETIMES BUT NOT CONSTANTLY AND THE DEALER REFERRED ME TO GMC SERVICE CENTER. THE GMC SERVICE CENTER BASICALLY EXPLAINED THE SAME THING, THAT THEY HAVE NO RECORD OF COMPLAINTS AND THOSE WOULD NOT BE COVERED BECAUSE THE LIGHT IS ACTUALLY BROKE OR OUT, AND THAT IS NOT COVERED. THEY ACTUALLY SUGGESTED I GO BACK TO THE PURCHASING DEALERSHIP WHICH IS THE ONE THAT SENT ME TO THEM, JUST GOT THE GO AROUND WITH NO ACTION. THIS IS A SERIOUS SAFETY ISSUE IF THE LIGHTS STOP WORKING SUDDENLY, ESPECIALLY AT NIGHT BECAUSE THE WHOLE LIGHT GOES BLACK. NOW I CANNOT GET MY VEHICLE REGISTERED DUE TO THE LIGHT AND WILL NEED TO FIX OR REPLACE A FACTORY ISSUE WITH THE LIGHT JUST TO GET MY VEHICLE INSPECTED AND REGISTERED.

I GIVE!!! NOW BREAK LIGHTS NOT WORKING!!! RIGHT BREAK LIGHT IS OUT AND LEFT DRIVER IS INTERMITTENT. VEHICLE HAS 37K ON IT AND WAS JUST PICKED UP FROM THE DEALER AFTER HAVING 1 OF MANY ISSUES THROUGH THE PAST YEAR RECTIFIED AND NOW THIS! THIS IS A SIGNIFICANT SAFETY HAZARD AND COULD TREMENDOUSLY INJURE SOMEONE. RIGHT NOW MY CAR CANNOT EVEN PASS INSPECTION DUE TO THE FAULTY EQUIPMENT INSTALLED BY THE MANUFACTURE THAT IS A DANGER TO MY SAFETY. I HAVE OWNED MANY GMC'S (6 TOTAL) THROUGH THE YEARS AND THIS BEING THE WORST!! THE LATEST, I HAVE HAD THE TORQUE CONVERTER REPLACED IN AUG 18 - DUE TO SHUDDERING AND VIBRATION. THEN THE STEERING COLUMN REPLACED DUE TO POPPING , BACK HATCH HINGE REPLACED DUE TO POPPING AND MALFUNCTION, BACK GLASS DOOR RUBBER GASKET REPLACED DUE TO LEAKING, SHARKFIN ANTENNA REPLACED DUE TO LEAKING, SUNROOF GASKET REPLACED DUE TO LEAKING, NEW TIRES AT 500 MILES DUE TO EXCESSIVE VIBRATION. BACK DOOR ADJUSTED DUE TO SLAMMING, AND ADDITIONAL SLIGHT ISSUES. THE RADIO HAS A CONSTANT GLITCH ON THE SCREEN SINCE DAY ONE THAT AFTER BEING TAKEN IN NUMEROUS TIMES, OF COURSE THE DEALER CANNOT REPLICATE THE PROBLEM AND KEEPS PERFORMING A FLASH UPDATE WHICH NEVER HELPS AND AS SOON AS I DRIVE OFF IT GLITCHES AGAIN. I HAVE CONTACTED GM REGARDING THE BRAKE LIGHTS, RADIO, AND NOW MY PASSENGER STEP IS MALFUNCTIONING NOT TO MENTION A RECALL WAS JUST RELEASED ON THE POWER STEERING. WILL THE REPAIRS EVER END? GUESS ONCE I TRADE IT IN ON ANOTHER MANUFACTURE AS THIS WILL MOST LIKELY BE THE LAST GMC I WILL EVER PURCHASE!! I DO NOT HAVE TIME TO LIVE MY LIFE AT THE DEALER FOR A HIGH END PURCHASE THAT IS THE WORST MISTAKE EVER!! NOT TO MENTION BEING A SAFETY HAZARD!!!

THE REAR LED TAILIGHT GOES IN AND OUT, WHILE DRIVING THE CAR. THE DEALER WILL NOT FIX THE PROBLEM UNLESS THE LIGHT IS NOT WORKING, BUT BECAUSE IT IS INTERMITTENT, WE CANNOT GET IT TO FAIL AT THE DEALERSHIP. WE HAVE HAD THIS PROBLEM FOR 2 YEARS AND IT IS A SAFETY ISSUE AS THE TAIL LIGHT WILL NOT WORK.

BRAKE LIGHTS ARE FAILING INTERMITTENTLY. DEALER HAS RECOMMENDED REPLACING BOTH TAIL LIGHT HOUSING ASSEMBLIES AT A SIGNIFICANT COST OF $750 EACH. DEALER HAS ALSO STATED THIS IS A "COMMON PROBLEM" OF THE 2015 GMC VEHICLES WITH AN LED BRAKE LIGHT DESIGN; NO EASY OR AFFORDABLE SOLUTION OUT THERE.

PE18012 · Brake Vacuum Pump Failure
Opened Nov 20, 2018 · Closed Apr 10, 2022
Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Hydraulic; Service Brakes, Hydraulic:power Assist:vacuum
On November 20, 2018, the Office of Defects Investigations (ODI) opened PE18-012 to investigate instances of sudden onset of a hard brake pedal that could result in extended stopping distance due to an issue with the brake assist vacuum pump in model year (MY) 2014 through 2016 GMC Sierra 1500 and Chevrolet Silverado 1500 series pickup trucks and MY 2015 through 2016 Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon SUVs.If the brake assist vacuum pump fails to operate as intended, the amount of brake power assist supplied to the driver can be significantly reduced, extending the subject vehicle stopping distance. GM stated that the root cause of pump failures was due to foreign debris such as oil sludge in the engine oil. GM stated that this debris can become trapped by the oil inlet filter screen. Under normal operation, this screen allows a small amount of oil into the brake vacuum pump. The foreign debris can, over time, clog the pump which can cause a loss of lubrication and a reduction in the amount of vacuum produced leading to a hard pedal and extended stopping distance.On December 13, 2018, GM issued a Special Coverage (N182202780) for the brake vacuum pump issue in MY 2014-2017 trucks and 2015-2017 SUVs on the K2XX platform for 6 years or 72,000 miles. Special Coverage repair includes the replacement of the vacuum pump and vacuum pump belt. Consumers received notification of the coverage via mail. On September 6, 2019, GM notified NHTSA that it was conducting safety recall 19V-645 which reprograms the electronic brake control module (EBCM) and included approximately 3.5 million trucks and SUVs. In October 2019, GM extended the terms of special coverage N182202780 to 10 years or 150,000 miles as well as now including the entire scope of recall 19V-645. In October 2020, GM expanded the scope of coverage N182202780 to include the MY 2018 Escalade and 2019 Tahoe.The remedy implemented in GM recall 19V-645 appears to be sufficient in addressing the safety-related concerns of this issue. Loss of vacuum assist now occurs at a progressive rate as well as there being a more timely warning of a brake problem to the driver through the driver information center (DIC). In view of the recall action and revision to the special coverage, this Preliminary Evaluation is closed. The agency reserves the right to take additional action if warranted by new circumstances. The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.
