NHTSA Complaint #11584454 — 2017 GMC SIERRA 1500

The vehicle would shudder when trying to accelerate. I almost was hit by a semi truck trying to merge onto the freeway. Made an appointment with the mechanic then a couple days later I was at a stop sign and the vehicle would not accelerate at all. I placed in park the tried shifting back into drive and still nothing. I had to turn the vehicle on and off twice before I was able to shift it in drive an it actully would accelerate. Even then it would shudder and not accelerate fully. Very dangerous. Just hit 100k miles. GMC Certified Mechanic said the transmission is shot and needs to be replaced. Cost to replace over $6,000.00 Bought the truck in 2020 for $35,500 and just paid it off.
