PURCHASED MY 2014 CHEVY SILVERADO AT THE END OF JUNE 2014 AND BY JULY 2014 WHILE TRAVELING TO WORK MY TRUCK EXPERIENCE A SEVERE VIBRATION THAT SHOOKED MY ENTIRE INTERIOR AND ESPECIALLY MY CENTER CONSOLE. TOOK MY TRUCK TO TWO LOCAL DEALERSHIPS AND THEY SAY MY TRUCK DRIVES AND HANDLES NORMALLY. AFTER READING OTHER COMPLAINTS BY OTHER OWNERS, I DECIDED TO WRITE MY OWN COMPLAINT. CHEVY CORPORATION NEEDS TO INVESTIGATE THIS MATTER BEFORE ANY TRAGIC INCIDENT HAPPE NS LIKE THE IGNITION SWITCH RECALL THAT INNOCENT PEOPLE DIED AND NOW THEY ARE PAYING MEGA BUCKS. ALSO REQUESTING OTHER OWNERS TO FILE A COMPLAINT SO OTHER TRUCK BUYERS WILL STAY AWAY FROM CHEVROLET AUTOMOBILES ENTIRELY. MY NEXT PURCHASE WILL PROBABLY A FOREIGN BECAUSE I AM HAVING TO MANY PROBLEMS AND NOTHING IS GETTING DONE. THANKS ALOT CHEVY, FROM SOON TO BE EX-CHEVROLET OWNER. *TR

THE VEHICLE WAS PURCHASED ON AUGUST 27TH 2014 AND HAD A BAD VIBRATION ON THE DRIVE HOME. IT HAS A WOBBLE SENSATION AT 35-45 MPH FELT STRONGEST AT 43 MPH THAT FEELS LIKE IT HAS A BENT WHEEL BUT IT DOESNT. WHEN YOU GET TO 65-70 MPH THERE IS A STRONG VIBRATION FROM THE TRUCK FELT STRONGEST AT 68 MPH AND IT ONLY OCCURS ON SMOOTH LEVEL ROADS AND EVEN CHANGING LANES DOES NOT CHANGE THE VIBRATION AT ALL SO IT IS NOT RELATED TO THE ROAD CONDITIONS OTHER THEN BEING FLAT AND SMOOTH. THE DEALER HAS MADE FIVE UNSUCCESSFUL ATTEMPTS TO FIX IT ALREADY AND CANNOT FIND THE PROBLEM AND CANNOT FIX THE PROBLEM AND HAS REFUSED TO TRY TO FIX IT ANYMORE. AFTER RESEARCHING THIS ISSUE I HAVE FOUND THAT ONE OUT OF FIVE GM TRUCKS (CHEVY & GMC) HAVE THIS SAME ISSUE EVEN THOUGH THERE ARE NOT MANY PEOPLE REPORTING THIS YET. DO NOT BUY OR LET ANYONE YOU KNOW BUY A CHEVY & GMC TRUCK IN THE 2014 OR 2015 YEARS, 1 IN 5 ARE LEMONS THE VIBRATIONS ARE SO BAD THAT IT WILL MAKE YOU CAR SICK AFTER A FEW MILES AND CAN AGGRAVATE EXISTING CONDITIONS SUCH AS PEOPLE WITH BACK ISSUES. THIS PROBLEM ALSO GREATLY REDUCES THE TRADE-IN OR RESALE VALUE OF THE VEHICLE AND WILL MAKE SELLING IT YOURSELF VERY PROBLEMATIC IF NOT IMPOSSIBLE. IF YOU LOOK ON YOUTUBE YOU WILL SEE PEOPLE ARE STARTING TO POST SOME VIDEOS TO SHOW THIS VIBRATION PROBLEM. *TR

THIS TRUCK WAS PURCHASED AT 8 PM ON 9/22/2014. WHEN DRIVING ON 9/25/2014, THE TRUCK VIBRATED AS THOUGH I WAS DRIVING OVER RUMBLE STRIPS AT APPROXIMATELY 40 MPH, 55-75 MPH. IN HI-2 MODE IN DRIVE, THE TRANSMISSION DID NOT SHIFT SMOOTHLY, SHIFTING WITH A MILD CLUNK AT LOWER GEARS. WE CALLED THE DEALERSHIP AND DESCRIBED THE ISSUES TO A SERVICE PERSON AND MADE AN APPOINTMENT TO BRING THE TRUCK IN FOR SERVICE ON 9/29/2014. THE DEALER STATED THAT THE PROBLEMS WERE PROBABLY DUE TO ALIGNMENT ISSUES. ON 9/28/2014, I DROVE THE TRUCK AND EXPERIENCED THE SAME SHIFTING AND VIBRATION ISSUES. I PULLED OFF THE FREEWAY NEAR MY DESTINATION AND STOPPED AT A LIGHT. WHEN I ATTEMPTED TO ACCELERATE FROM THE STOP, THE TRUCK WOULD NOT MOVE AND "REVVED". IT HAD SWITCHED INTO NEUTRAL WITHOUT ANY INPUT FROM ME. THE TRANSMISSION SHIFT LEVER STILL INDICATED THAT I WAS IN DRIVE MODE. I DRIFTED INTO THE INTERSECTION, UNABLE TO GET THE TRUCK TO MOVE. I WAS ABLE TO SHIFT INTO PARK, THEN NEUTRAL, AND THEN DRIVE. THE TRUCK BEGAN TO DRIVE AND THEN I FELT A STRONG "THUNK" THAT FELT AS THOUGH I HAD BEEN REAR-ENDED BY A CAR GOING AT LEAST 25 MPH. THE TRUCK THEN DROVE NORMALLY FOR APPROXIMATELY 150 FEET. I HAD TO STOP AT THE LIGHT ON THE OTHER SIDE OF THE UNDERPASS AND THE SAME THING HAPPENED AGAIN, LEAVING ME DRIFTING INTO AN INTERSECTION. I WAS AGAIN ABLE TO GET THE TRUCK GOING AFTER A MINUTE OR SO, WITH THE SAME STRONG "THUNK". I CALLED ONSTAR TO HAVE THE TRUCK TOWED TO THE DEALERSHIP BECAUSE IT IS UNSAFE TO DRIVE. ON THE FOUR OTHER DAYS THAT WE HAVE OWNED THIS TRUCK, IT WAS DRIVEN ONLY A FEW MILES EACH DAY, AT LOW SPEEDS. I AM EXTREMELY CONCERNED. THE TRUCK IS UNSAFE TO DRIVE AND HAS LESS THAN 300 MILES ON IT. ADDITIONALLY, SOME OF THE ISSUES I HAVE EXPERIENCED ARE SIMILAR TO THOSE ADDRESSED BY A RECALL, BUT THIS TRUCK'S VIN IS NOT LISTED IN THE RECALL. *TR

WHEN THE TRUCK REACHES A SPEED OVER 35 MPH THE STEERING WHEEL, THE SEAT, AND THE ENTIRE TRUCK HAS A VIBRATION. I LIVE IN EAST TENNESSEE. I PURCHASED THE TRUCK IN GEORGIA. IT IS ABOUT A THREE HOUR DRIVE FROM WHERE I PURCHASED THE TRUCK TO MY HOME. ON THE DRIVE HOME I NOTICED THE VIBRATION RIGHT AWAY. I THOUGHT IT MAY BE A TIRE BALANCE ISSUE SO I CONTINUED THE TRIP HOME. THE NEXT DAY I TALKED WITH THE LOCAL DEALER AND WAS INFORMED I NEED 500 MILES ON THE TRUCK BEFORE THEY WILL WORK A VIBRATION ISSUE. WHEN I TOOK THE TRUCK FOR SERVICE A FEW DAYS LATER I WAS INFORMED THAT SEVERAL TRUCKS HAVE THIS SAME ISSUE AND GM DOES NOT KNOW WHAT TO DO ABOUT THE ISSUE. THE DEALER BALANCED THE TIRES AND TOLD ME THAT IS ALL THEY CAN DO ABOUT THE VIBRATION. THROUGH SEARCHING THE INTERNET AND TALKING WITH OTHER DEALERS I HAVE FOUND THAT MAY PARTS HAVE BEEN REPLACED WITH NO HELP. DRIVE SHAFTS,AXLE SHAFTS, WHEELS AND TIRES HAVE BEEN REPLACED AND REAR ENDS HAVE BEEN REBUILT. NOTHING SEEMS TO HELP. MOST DEALERS HAVE WORKED THIS ISSUE ON SEVERAL TRUCKS. IF THIS VIBRATION IS COMING FROM ANY PART OF THE DRIVE TRAIN OR SUSPENSION AND THE PART HAS A CATASTROPHIC FAILURE IT CAN CAUSE SERIOUS INJURY OR POSSIBLY DEATH. *TR

MY 2014 CHEVY SILVERADO 1500, LTZ, Z71 STARTED TO HAVE NUMEROUS ISSUES SINCE THIS PAST APRIL. THE TRUCK HAS BEEN IN THE UNETHICAL LANDERS MCCLARTY CHEVROLET IN HUNTSVILLE, ALABAMA SEVEN TIMES WITH ONLY THE SMALLEST OF THE ISSUES BEING FIXED. 1ST ISSUE WAS THE DRIVER SIDE SEAT MOVED WHEN TURNING LEFT OR RIGHT. THE DEALER'S SERVICE DEPARTMENT INFORMED ME THERE WAS NO FIX AND THAT THE SEAT WAS WITHIN MANUFACTURES SPECS. THE SEAT MOVED TO THE POINT THAT THE VENTILATED SEAT COOLER PLUG DISCONNECTED. THE SERVICE DEPT EVENTUALLY "FIXED" THE SEAT AND RECONNECTED THE PLUG. LASTLY THE ISSUE I CANNOT GET RESOLVED THROUGH GM CORPORATE, DEALER SERVICE DEPARTMENT OR THE REGIONAL GM MANAGER. MY TRUCK "SHAKES" FROM SPEEDS OF 65 MPH AND GREATER. THE SERVICE DEPT FIRST TOLD ME I NEEDED AN ALIGNMENT AND HAVE THE TIRE ROTATED AND BALANCED. THE SHAKE STILL CONTINUED, SO I COMPLAINED AGAIN TO THE SERVICE DEPT. THIS TIME I WAS TOLD THAT TWO TIRES WHERE "BAD" DO TO ROAD FORCE AND REPLACED THEM. THE TRUCK STILL SHAKES LIKE A STRIPPER SO I EMAILED THE CEO OF GM ON 11 JULY AND ASSIGNED AN EXECUTIVE LIAISON TO WORK THE ISSUE. SINCE THEN MY TRUCK HAS BEEN IN THE SERVICE DEPARTMENT TWICE. EACH TIME I WAS CALLED A LIAR INDIRECTLY BY THE SERVICE DEPARTMENT MANAGER "[XXX]" AND THE DISTRICT MANAGER "[XXX]" AFTER THEY TEST DROVE THE TRUCK AND COULDN'T REPLICATE THE COMPLAINT. I HAD THE SERVICE DEPT FOREMAN "[XXX]" RIDE ALONG WITH ME AS I DROVE THE TRUCK AND POINTED OUT THE "VERY" NOTICEABLE SHAKE AT HIGH WAY SPEEDS. AFTER NUMEROUS PHONE CALLS TO THE SERVICE DEPT, GM CORPORATE, I FOUND OUT THAT THE SERVICE DEPT CAN UTILIZE A VIBRATION ANALYZER ON THE TRUCK. THIS HAS NOT TAKEN PLACE OR EVEN CONSIDERED. I CONTINUE TO DRIVE THE TRUCK WITH THE SHAKING BECOMING WORSE WITH EACH MILE. JUST LIKE THE IGNITION SWITCH PROBLEM, GM DOWN PLAYS THE ISSUE AND LETS THE PROBLEM COMPOUND. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

AT LESS THAN 2,000 MILES, THE FRAME AND REAR AXLE IS RUSTING THROUGH THE "PROTECTIVE" WAX COATING. WHERE MY DEALER PLACED JACK POINTS WHEN JACKING UP THE VEHICLE DURING PRE-SALE INSPECTION, THERE ARE DISTINCT RUST MARKS IN THE SHAPE OF THE JACK POINT. THE AXLE HAS RUST SPOTS INCREASING IN SIZE EVERY WEEK. THE FRAME HAS RUST SPOTS INCREASING IN SIZE AND APPARENT SEVERITY EVERY WEEK. THE WAX COATING IS OFTEN FOUND IN FLAKES UNDER MY TRUCK IN MY GARAGE IN THE MORNING. I HAD A 2011 SILVERADO THAT, AT 22K, HAD ZERO FRAME RUST AND IT WAS EXPOSED NUMEROUS TIMES TO CHICAGO AND MINNEAPOLIS WINTERS, INCLUDING THE HEAVY ROAD SALT. THIS NEW TRUCK HAS NEVER LEFT GEORGIA SINCE ITS PURCHASE. I AM CONCERNED ABOUT THE STRUCTURAL INTEGRITY OF THIS VEHICLE OVER TIME IF THE FRAME WILL RUST AS MUCH AS IT HAS IN LESS THAN 2,000 MILES. WHAT WILL IT LOOK LIKE AT 50K MI.? *TR

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence & remedy
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017.

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.
