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.

    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.

  1. Power train, Vehicle speed control, Fuel/propulsion system, Sep 13, 2024

    Recently I've noticed that when I try to accelerate or take off from stop it does not pick up speed as use to. My engine rpms rise but speed is getting less and less. I've also noticed my transmission temperature is staying between 190-200 degrees which gm has already had recalls over pertaining to this style transmission having issues due to high heat. Vehicle has always had maintenance kept up with and never abused. Have taken to local shop since warranty ran out several times for inspection of transmission well my complaints in regards and have fluid done. Recently I've noticed fluid is needing to be replaced more frequently due to losing viscosity from overheating and being burnt, has the familiar and similar smell of toast being burnt. This is a 2016 Tahoe ltz w just over 200k, yes in some ways a lot but considering the cost of vehicle new/age/synthetic fluids and everything it seems to me the transmission should last longer especially considering it's been maintained. These new vehicles are outrageous and the transmissions are very expensive as well, considering these same transmissions have had recalls from GM I'm a little aggravated and frustrated on how some can and can't. I'm familiar and aware they say it's per manufacturing plant and particular models but confused as to how if the transmission that has had recalls for overheating doesn't comply to all the transmissions that are same type, I think it's bogus n a way not to be responsible for accepting failures n having to replace all parts so gm says it only happened here n with these parts. I guarantee you if someone would take a look at gm shipping and papers they would see it. If a 2016 4l60e had problems it's more than likely all of them in that year had all same parts so therefore all acceptable to failure, its not like transmission maker chose different parts to send to different plants or this get that no thats just b.s. so there not responsible for all of them so they pick plant with most failures

    I was constantly smelling a strong odor of gas coming from the inside/outside of my 2015 Chevy Tahoe. When I purchased the vehicle in 10/23 everything appeared fine. I researched the internet to determine what the problem could be & found dozens of similar situations. People saying the fuel line rubs the undercarriage of the vehicle causing a pin hole size in the fuel line causing it to leak gas. Currently my vehicle is in the shop and the problem is TBD.

  23. Electrical system, Service brakes, Nov 19, 2023

    On Wednesday, 11/15/23, I was sitting in my vehicle while it was parked and running for several minutes. After a few minutes, the alert chime went off and the message "Service Trailer Brake System" was displayed on the dash notifications. This alert persisted for several minutes. Since this initial incident, the same alert has displayed 3 or 4 more times, but while driving. It repeats persistently, causing a major distraction, blocking my speedometer, and disabling bluetooth features. I nearly wrecked because of the distraction and have not been able to tow my trailer because of the risk of of the trailer brakes not working. I have an appointment scheduled with my mechanic on 11/28/23 to get this repaired, but have recently learned of several incidents of this same alert from other GM vehicle owners. This seems to be a defective wire harness and needs to be recalled as it is unsafe and renders the vehicle useless for many intended purposes.

  24. Service brakes, Oct 27, 2023

    While driving the breaks failed to work. Then when I started pumping the brakes again it took longer than normal to respond and I had to press really hard. I was only going a few miles per hour in a parking lot. Now 5 days later it's happening all the time. It's also making a click noise when I press the pedal.

  25. Fuel/propulsion system, Oct 6, 2023

    The high pressure fuel line from the fuel pump to engine sustained a pinhole leak over the fuel tank. Fuel leaked over top of tank and ran down front drivers side front of tank. Discovered the leak after noticing strong fuel odor inside vehicle. Took to shop. The fuel line is installed as so it will rub undercarriage of vehicle. This is what happened to mine. This is a factory install and the lines are doomed to fail because of this. The excessive contact rubs holes into the lines. This seems to be a common problem with the 2015, according to my research. There are hundreds of these same complaints with this year listed all over repair sites on the internet. I believe this needs looked into, as flammable fuel leaking suddenly can be a hazard.
