THIS POST IS ABOUT MAKING THE PUBLIC AWARE OF A POTENTIAL PROBLEM. ALTHOUGH THE MANUFACTURER DID NOT STEP UP AND DO THE RIGHT THING, I'M CONCERNED OTHERS MAY HAVE DEALT WITH THIS PROBLEM OR IT MAY HAPPEN IN THE FUTURE. ON AUGUST 29, 2018, MY TRUCK WAS PARKED ON MY DRIVEWAY BY 4PM AFTER RUNNING ERRANDS FOR A COUPLE OF HOURS. AT 6PM MY HUSBAND WENT OUT TO GET SOMETHING OUT OF IT AND SAW IT HAD CAUGHT ON FIRE. NOTHING WAS LEFT PLUGGED IN AND THERE WAS NOTHING FLAMMABLE IN THE TRUCK. THE FIRE DEPT WAS CALLED AND UPON INSPECTION STATED THE FIRE HAD STARTED IN THE CENTER CONSOLE AND SPREAD TO THE FRONT PASSENGER SEAT. THE CAUSE OF THE FIRE LOOK TO BE WIRING THAT OVERHEATED INSIDE THE CONSOLE WHERE THE WIRING CONNECTED TO 2 USB PORTS. GM INSPECTED THE DAMAGE AND FOUND THERE WAS NOT A MANUFACTURER DEFECT AND THE CAUSE OF THE FIRE WAS FROM AN EXTERNAL SOURCE. IRONICALLY, THEIR 3RD PARTY "EXPERT" FIRE INVESTIGATOR WAS NOT AWARE THERE WAS A WIRING HARNESS LOCATED BEHIND THE USB PORTS AND HAD TO BE SHOWN THEIR LOCATION. MY INSURANCE COMPANY IS NOW INVESTIGATING THE INCIDENT. I'M ASKING THEM TO LOOK INTO THE 12V POWER OUTLET POSSIBLY OVERHEATING AS I KNOW OF SOMEONE WHO HAD THEIRS OVERHEAT IN THEIR 2018 CHEVY SILVERADO. THE DAY AFTER THE FIRE I SENT PHOTOS TO THEM AND THEY COULD NOT BELIEVE THE DAMAGE. WHEN I TOLD THEM THE OUTCOME OF GM'S INVESTIGATION THEY WERE DUMBFOUNDED. I'M FORTUNATE NO ONE WAS HURT, BUT AM AFRAID THIS MAY HAPPEN TO SOMEONE ELSE. I MADE A 40K + INVESTMENT WITH GM AND LITERALLY "WAS BURNED". I WANT OTHER TO BE AWARE OF THE POTENTIAL FIRE DANGER. I DID EXPECT GM TO STEP UP AND TAKE CARE OF THEIR LOYAL CUSTOMER (I'VE BOUGHT 8 GM VEHICLES), BUT IT APPEARS THE ALMIGHTY DOLLAR WON OUT. THANKFULLY, IN MY CASE, NO ONE WAS HURT.

AC CONDENSER UNIT STARTS LEAKING AND VEHICLE AC STOPS BLOWING COOL AIR. THIS MAY ONLY SEEM LIKE A INCONVENIENCE, BUT HERE IN THE SOUTH SUMMERS ARE UNBEARABLE WITHOUT AC. OCCUPANTS OF VEHICLES COULD EASILY SUCCUMB TO HEAT EXHAUSTION. IT COULD BE DIFFICULT FOR THE DRIVER TO KEEP SWEAT OUT OF HIS OR HER EYES. THIS INCONVENIENCE COULD LEAD TO DISTRACTED/DISGRUNTLED DRIVING. THERE ARE ACTUALLY A NUMBER OF REASON THAT THIS COULD POSE A SERIOUS SAFETY RISK. GM IS WELL AWARE OF THIS ISSUE AND HAS FAILED TO PROPERLY ADDRESS THE SITUATION. I DIDN'T NOTICE THAT MY AC WASN'T WORKING UNTIL MY VEHICLE HAD 37,000 MILES ON IT. I'M POSITIVE THAT IT TOOK LONGER THAN THE FEW DAYS BETWEEN ME BEING AT 36,000 AND 37,000 MILES FOR THE REFRIGERANT TO COMPLETELY EXIT THE SYSTEM AND THE AIR TO NOT WORK. GM HAS OFFERED A HALF-HEARTED GOODWILL REPAIR THAT IS STILL JUST SHY OF $600. THIS HAS BEEN A KNOWN ISSUE FOR GM FOR YEARS AND IS NOT ONLY NEGLIGENT, SELLING ME THIS VEHICLE IN NOVEMBER OF 2015 ESSENTIALLY CONSTITUTES FRAUD.

AT 50,000 MILES, AND 24 MONTHS AFTER PURCHASING IT NEW, THE AIR CONDITIONING STOPPED WORKING DUE TO A FAULTY CONDENSER. AFTER INVESTIGATING THIS PROBLEM I FOUND OUT THAT THERE IS AN EXTREMELY HIGH FAILURE RATE OF GMC TRUCKS FOR THE SAME EXACT PROBLEM. IT IS A WELL KNOWN DEFECT PER SEVERAL GM DEALERS WHO ARE LEFT TO DEAL WITH THE PROBLEM. A BRACKET TO SECURE THE A/C LINE WAS NEVER INSTALLED WHEN VEHICLE WAS BUILT, CAUSING MOVEMENT IN THE LINE WHICH EVENTUALLY CAN RUIN THE CONDENSER, AC LINE AND COMPRESSOR. I ASKED GM DEALER TO FIX UNDER WARRANTY BUT WAS TOLD THAT THE BEST THAT GM WAS WILLING TO DO WAS TO PAY 40% OF THE REPAIR BILL. THIS IS UNACCEPTABLE, AS THE DEFECT IS WIDESPREAD IN MANY OF THEIR LIGHT TRUCKS

2EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
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.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

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.
