NHTSA investigations into the 2014 GMC Yukon XL

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

1 investigation is still open.

EA21002 Opened 17 Sep 2021 Still open AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

Desiccated Air Bag Inflator Rupture

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.C...

Recalls on the 2014 GMC Yukon XL

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2021028 295,974 units in Canada

Airbag

Issue: On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, may eventually degrade the propellant contained in the passenger-front airbag. This could cause the airbag to deploy with more force than normal. If the airbag inflator ruptures, fragments could be propelled toward vehicle occupants or cause damage to the airbag assembly, preventing its proper function. Safety Risk: If the vehicle is involved in a crash requiring an airbag deployment, the airbag inflator could rupture and create a risk of injury. Corrective Action: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the passenger-front airbag. Note: The Canadian climate results in the propellant degrading slowly. This recall is being conducted as a precaution to address future risk. It is expected that all airbag inflators will be replaced before their function would be affected.

Recall 2019420 5,327 units in Canada

Other

Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.

Recall 2014432 5,071 units in Canada

Electrical

On certain vehicles, the chassis electronic module may have been contaminated at time of manufacture, which could cause an electrical short to occur within the module. This could cause the vehicle's check engine light to be displayed, or cause the engine to fail to start or stall, resulting in a loss of motive power. If the vehicle is equipped to support electric trailer brakes, the vehicle could also lose trailer brake function and display a "Service Trailer Brake System" indicator. These issues could increase the risk of a crash resulting in injury and/or damage to property. Correction: Dealers will replace the module with a revised part.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

ELECTRICAL SYSTEM:IGNITION

The contact's wife owns a 2014 GMC Yukon XL. The contact stated that on several occasions, the vehicle failed to start with the key in the ignition. The failure persisted and a yellow anti-theft warning symbol was displayed on the instrument panel. The contact stated that on one occasion the vehicle failed to start after several attempts and the contact became trapped inside the vehicle for approximately 5-6 minutes and was unable to unlock or open the doors. The contact attempted to use the remote and the key to unlock the doors but there was no electrical functions available. The contact stated that the temperature was very hot inside the vehicle, and he was starting to be deprived of oxygen due to the excessive heat. The contact’s wife who was inside the residence was able to unlock the vehicle from outside after several attempts of pressing and pushing the door handle, the key, and the remote. The contact stated that after the door was unlocked, the contact jiggled the key inside the ignition switch and the vehicle started. Medical attention was not needed; however, the contact stated that the failure could have been fatal if he did not have the cellphone to call for assistance. The contact eventually restarted the vehicle and drove to the dealer. The contact was provided a diagnostic fee and the vehicle remained with the dealer.

AIR BAGS

AFTER SWITCHING TO PASSING LANE AND SEEING TRAFFIC IN LANE AT STANDSTILL I SWIFTLY JAMMED ON BRAKE PEDAL. BRAKES FAILED TO PROVIDE ADEQUATE STOPPING ABILITY AS THOUGH THEY WERE COATED WITH GREASE. DESPITE HAVING WELL IN EXCESS OF 100 FT THE VEHICLE WOULD NOT STOP. REAR ENDED VEHICLE IN FRONT WITH ABOUT 12K IN DAMAGE TO FRONT OF THE VEHICLE. AIR BAGS DID NOT DEPLOY. ORIGINAL ROTORS AND PADS WERE REPLACED AFTER EXPERIENCING SEVERE BRAKE FADING WHEN HOT PRIOR TO ACCIDENT. DRILLED AND SLOTTED RACING ROTORS WERE INSTALLED. AFTER THE VEHICLE WAS REPAIRED AND PLACED BACK ON THE ROAD, I TESTED WITH THE SAME BRAKES WITH A HARD STOP FROM 80 MPH. THE BRAKES WORKED SO WELL THE FORCE OF THE STOP WAS PULLING ME OFF MY SEAT. SEVERAL WEEKS LATER, I WAS CUT OFF BY ANOTHER DRIVER ON THE HIGHWAY DOING ABOUT 40MPH LESS THAN I WAS. I JAMMED ON THE BRAKES AND AGAIN THERE WAS INSUFFICIENT BRAKING LIKE BEFORE EXCEPT NO COLLISION. ONCE MORE I TESTED AT A HARD BRAKE FROM 80 MPH AND AGAIN IT STOPPED EXTREMELY WELL. APPARENTLY THE FAILURE OF SUFFICIENT BRAKING CAME WITH APPLICATION OF ABS SYSTEM OTHERWISE THE STOPPING POWER WAS EXCEPTIONAL. I STRONGLY URGE INVESTIGATION OF GM ABS BRAKING. I AM A PROFESSIONAL DRIVER WITH IN EXCESS OF 4 MILLION MILES WITH ALL CLASSES OF VEHICLES IN ALL EXTREMES. THE WORST DAMAGE I EVER HAD ON THE HIGHWAY WAS A BROKEN HEADLIGHT IN 1975 UNTIL THIS ACCIDENT. THE ACCIDENT SHOULD NOT HAVE HAPPENED AS MY REACTION WAS TIMELY AND THE DISTANCE TO STOP MORE THAN ADEQUATE. THE AIR BAGS FAILED TO DEPLOY DESPITE THE ENTIRE NOSE OF THE VEHICLE BEING DESTROYED AND PUSHED BACK TO THE ENGINE BLOCK.

THIS WILL BE THE 3RD TIME IN THE LAST 4 YEARS I HAVE EXPERIENCED MY YUKON XL 2004 MODEL COMPLETELY SHUTTING DOWN WHILE ALL 3 TIMES DRIVING ON THE HIGHWAY AT A SPEED AVERAGE OF 65 MPH. WITH NO WARNING AT ALL. ALL 3 TIMES HAVE BEEN WHILE DRIVING THIS VEHICLE OVER A 4 HOUR PERIOD FOR FAMILY VACATION. MOST RECENTLY WAS THIS PAST LABOR DAY WEEKEND. WE HAVE REPLACED SENSORS, FUEL PUMP, AND MOST RECENTLY HAD THE ENGINE REPLACED WHICH IS WHY I KNOW FOR CERTAIN IT CANNOT BE RELATED TO ANY OF THE ABOVE. THANKFULLY I WAS NEAR A EXIT RAMP EACH TIME AND WAS ABLE TO PULL OVER SAFELY. ALL 3 TIMES I HAVE WAITED ABOUT 15 MINUTES AND THE CAR WILL START BACK UP -AND NO ONE SEEMS TO KNOW WHAT IS WRONG WITH IT.

UNKNOWN OR OTHER

THERE ARE 2 CRACKS IN THE DASHBOARD, 1 ABOVE THE STEERING WHEEL INSTRUMENT PANEL AND ONE AT THE CORNER OF THE PASSENGER SIDE AIRBAG. THEY APPEARED OUT OF NOWHERE AND WITHOUT ANY ACCOMPANYING MOTOR VEHICLE CRASH OR OTHER PHYSICAL CAUSE. I FOUND THE CRACKS AS I WAS WIPING THE DASHBOARD OFF WITH A MICROFIBER TOWEL. THE CRACK OVER THE INSTRUMENT PANEL GREW APPROXIMATELY 3 INCHES WHILE I WAS DRIVING TO THE DEALERSHIP. I WAS TOLD THAT SINCE MY WARRANTY WAS EXPIRED (EXPIRED ON 12/06/2016) AND I WAS OVER THE WARRANTY MILEAGE (MY MILEAGE WAS 36180, WARRANTY ONLY GOOD FOR 36000) THAT MY VEHICLE WAS NOT COVERED AND I WOULD HAVE TO PAY OVER $1800 + TAX TO REPLACE. I HAVE SEARCHED ONLINE AND FOUND SIMILAR GM VEHICLES HAVE HAD THE SAME PROBLEM, AND WITH CRACKS IN THE EXACT SAME PLACE. THIS IS A VEHICLE DEFECT AND GIVEN THE FACT THAT IT'S SO CLOSE TO THE PASSENGER SIDE AIRBAG PRESENTS A SAFETY CONCERN THAT THE WHOLE DASHBOARD COULD BE DISLODGED AND BECOME A FLYING HAZARD SHOULD THE AIRBAG INFLATE DURING A CRASH.
