Recalls and investigations

  1. Seat belts, frontApr 8, 2021

    General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.

    A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.

    GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.

  2. Service brakes, hydraulic, antilock/traction control/electronic limited slip, wheel speed sensor/tone ringOct 24, 2019

    General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.

    Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.

    GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

    General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

    As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.

    GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.

These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

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.

    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.

    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.

  1. Power train, Sep 29, 2022

    My truck goes into “neutral” or doesn’t have power while driving at times and can cause a car crash.

  2. Power train, Engine, Apr 20, 2022

    My vehicle recently started "shuttering" while driving. Service report says it is a "common GMC issue with the Torque Converter", $3200. They also reported a "substantial leak" in the radiator, and again, says it is a very common fault of GMC Trucks. And another $2700. If these conditions are as common as they indicate, why are there no corrective measures?

  3. Power train, Mar 30, 2022

    I was driving and was almost home when I heard a pop and started getting jerked back and forth and then just slowed down almost to a complete stop with vehicles approaching quickly almost causing a multiple vehicle pile up I’ve heard multiple people complain about the particular transmission that is put in these gmc and chevy 1500s and am just confused with all of the problems I see on the internet and hear from peers in person why it has not been recalled yet if need be I will make a survey of gmc and chevy owners to let it be known that the transmissions on these vehicles were poorly built and need to be recalled before anybody has this problem that I had today

    From time to time the vehicles power system will surge, blink, and generally act up. The priblem is intermittent. The check engine light will come in then go off, the engine has completely cut off several times while driving, the transmission acts up, radio will turn off, 120v outlet will turn off, occasionally the vehicle will fun for 5-15 seconds after being turned off and then sputter off. And 95% of the time the truck is absolutely fine.

    2014-2015 GMC SIERRAS WERE PRODUCED WITH A KNOWN FAULTY A/C CONDENSER WITH A BAD WELD THAT CAUSES AN A/C SYSTEM LEAK REQUIRING REPLACEMENT. THERE HAS BEEN AN OVERWHELMING FAILURE OF THE PRODUCT ACROSS THE COUNTRY, SO BAD SO THAT IT EVEN MADE THE NEWS. GM BECAME AWARE OF THIS ISSUE AND SENT NEW (PROPERLY PRODUCED) CONDENSERS TO THEIR PRODUCTION LINES FIRST, LEAVING HUNDREDS OF GMC OWNERS WITHOUT A/C OVER THE SUMMER. THEY PUT OUT A "SPECIAL RECALL" ON A VERY SMALL NUMBER OF VINS SAYING IT "MAY" HAPPEN IN OTHER VINS. THERE IS AN OVERWHELMING VOLUME OF COMPLAINTS ONLINE (INCLUDING MYSELF) WHERE GM IS ACKNOWLEDGING THIS ISSUE BUT REFUSING TO COVER THE REPLACEMENT COST OF THEIR FAULTY PART FOR HUNDREDS OF OWNERS HAVING THIS ISSUE. THIS REPAIR COST ME A LITTLE OVER $1300. IN THE SAME SERVICE VISIT FOR MY AC CONDENSER IT WAS IDENTIFIED THAT MY RADIATOR WAS LEAKING. THIS WAS DUE TO A FAULTY THERMOSTAT CAUSING STRESS FRACTURES IN THE RADIATOR CAUSING COOLANT TO LEAK. THIS ISSUE HAS ALSO BEEN IDENTIFIED BY GM HOWEVER ONLY A SELECT FEW VIN'S RECEIVED WARRANTY RECALLS. MY TOTAL REPAIR COST TO FIX BOTH ISSUES WAS IN EXCESS OF $4000. BOTH PROBLEMS ARE KNOWN TO GM YET THEY HAVE NOT REMEDIED THE ISSUE FOR EVERYONE.
