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.

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.

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.

I am experiencing ongoing issues with the 6L80E transmission that have significantly affected the performance and reliability of my vehicle. The transmission shifts harshly between gears, hesitates when accelerating, and occasionally slips before engaging. There is also a noticeable shudder during acceleration and inconsistent shifting, especially at lower speeds. These problems have become more frequent over time and raise concerns about the safety and dependability of the vehicle. The transmission does not operate as expected for normal driving conditions, and the issues negatively impact the overall driving experience. I am requesting a thorough inspection of the transmission, an explanation of the cause of these issues, and an appropriate repair or resolution to restore the vehicle to proper working condition.

Catastrophic transmission failure. Original transmission failed at 113,00 miles. I replaced it at the dealership with a factory rebuilt transmission and that transmission failed after only 40,000 miles. Now the vehicle is back in the dealership shop and they want me to replace the transmission a third time. This transmission is the 6L80 which is prone to fail, the torque converter fails and the transmission locks up I contacted General Motors and filed a complaint with them and they said they would not take any action or assist me with the repair.

Within the first week of buying my 2014 GMC 1500 SIERRA, the transmission fluid was black in griddy. I have had it flushed, then filter changed and new fluid put in within 2 week time frame. A week later had to put a new transmission in it. It barely would drive. So a purchase at 2,999 then to a transmission 4,800 and new control arm with ball joint with new axels. They were busted. Another 2,000. Its sicking. Advice

I was driving around a lake with my family. We were fishing. I had no warning at all and my transmission started to sputter and jerk extremely bad and my brakes did not work at the same time. I had to use my parking break to stop my family and I from going into the lake at 40mph. I looked up on many websites and forums and saw multiple people with the same issue. I am afraid that this will happen to a young driver and it be very tragic. Please do a recall. My truck is still sitting at my house broken. I am on disability and can not afford to fix it. I just keep paying my payments with no use of my truck. Please I beg of you.

At slow speeds, multiple times, I have had the truck completely have an electrical failure and the engine shut off. I have replaced the negative battery cable and ensured all connections are good. This has happened on streets when turning and in parking lots. When this happens all of the screens in the truck flicker and the service stabilitrack light comes on and then everything goes out, to include the engine. Myself, my family, and other drivers have been out at risk when the truck completely shuts off on a street. The dealership has not been able to give me an answer. There are many forums online where the 2014-2018 year models of this and similar GM vehicles have had the same problem. We need a specific fix for this before someone gets seriously injured or killed.

Going under 15mph, applying the brake causes the pedal to become stiff and lock up and not work. This has caused me to almost hit someone in traffic. I immediately got off the road and got my vehicle to a safe location off the road . Communicating with a dealer today to confirm possible recall issue or potential repairs.
