I had first seen a check engine light for a month and it would come on and off and sometimes it would stay off for about a week before it comes back on and do the same thing. I had noticed some slippage within the transmission a week prior to this incident and was looking to take it in for an inspection but money is tight so I couldn’t afford to go in for an inspection, especially a repair. I was driving to work and the vehicle was doing its slippage and I go about a mile or two until I reach an intersection, I came to a red light and stopped, when it turned green, I started pressing on the gas but the car didn’t move, it only revved. I then proceeded to put it in park and turn it off then on, only for it to do the same thing. So from there I had it pushed off into a nearby parking spot and then towed to a wrenchrite where they had confirmed it had nothing to do with the transmission fluid or anything minor. I then had it taken to Emory Services and they had confirmed the transmission its self had been fried.

Seat belts: pretensioner
- What is wrong
- General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. 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.
- Risk
- 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. Owners may contact Buick customer service at 1‑800‑521‑7300, Cadillac customer service at 1‑800‑458‑8006, Chevrolet customer service at 1‑800‑222‑1020, or GMC customer service at 1‑800‑462‑8782.
