FAULTY, POORLY MADE TAIL LIGHTS THAT NEED TO BE ENTIRELY REPLACED (NOT JUST THE BULB) AT MORE THAN $700 EACH. WHEN SPENDING SO MUCH ON A CAR, THIS IS LITERALLY INSANE NOT TO BE COVERED UNDER ANY WARRANTY. GMC DRIVERS DESERVE MORE THAN THIS POORLY MADE LED LIGHT SYSTEM. THE PLASTIC WINDOW TRIM PIECES ALSO DETACH DUE TO CHEAP PLASTIC CLIPS. I'VE HAD TO LITERALLY USE DOUBLE SIDED TAPE AND GLUE TO STICK THEM BACK ON A $70K+ CAR. IT'S HUNDREDS OF DOLLARS TO REPLACE PIECES THAT ARE LITERALLY PART OF THE BODY OF THE VEHICLE.

MY GMC YUKON XL VIBRATES BADLY AT ALL SPEEDS BUT INTENSIFIES AT SPEEDS BETWEEN 40-55. THE VIBRATION CAN BE FELT THROUGH THE WHOLE FRAME OF THE CAR. THE CABIN CREATES A THROBBIING SOUND, LIKE A HELICOPTER INSIDE THE CAR. THE STEERING WHEEL VIBRATES. THE CAR CONSUMES OIL AT AN ALARMING RATE WITH NO VISIBLE LEAKS OR NOTICABLE EXHAUST. THE CAR SURGES UNEXPECTEDLY SOMETHINES AROUND CORNERS OR BACKING OUT OF PARKING SPOTS. AND THE REAR "CLUNKS" WHEN ACCELERATING FROM A SLOW SPEED SUCH AS ONTO A HIGHWAY ENTRANCE RAMP. THE REARVIEW CAMERA A IS TOTALLY WORTHELSS IN LOW LIGHT LEVELS AND CANNOT BE USED FOR SAFE BACK UP OPERATIONS. DEALER HAS HAD THE CAR FOR OVER 50 DAYS AND HAS REPLACED THE TRANSMISSION, REPLACED THE TORQUE CONVERTER, HAS REPLACED THE STRUTS AND SHOCKS AND HAS CHANGED FLUISD AS PER GM INSTRUCTION. IN ALL THIS TIME AND OVER 6 VISITS, THEY CANNOT FIX AND HAVE TOLD ME THAT GM HAS SAID THIS IS THE "NEW NORMAL". IF THIS IS NORMAL, WHY DID THEY SPEND SO MUCH TO TRY AND FIX SOMETHIG THAT WAS NOT WRONG? THE DEALER ALSO TOLD ME THAT THE REAR VIEW CAMERA WILL NOT WORK PROPERLY BECUASE OF ALL OF THE FACTORY OPTIONS ON THE CAR AND THAT DEGRADES THE QUOALITY OF THE IMAGE. GM HAS NOT CONTACTED ME ALTHOUGH I HAVE REQUESTED THROUGH THE DEALER THAT THEY DO SO. I SEE THIS IS A COMMON PROBLEM WITH GMC CARS OF THIS YEARS MODEL. I WOUL DLIKE TO SEE ACTION TAKEN AGAINST GMC TO CORRECT THIS OR MAKE ME WHOLE.

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.
