What owners report
I've noticed since the first month of owner ship back in 2018, that something was wrong with my transmission. I own a 2017 Chevy Silverado with the 8 speed transmission. Not only had it been discouraging, it's disturbing, and possibly even unsafe. From 1st to 2nd gear there is a hard shift in the transmission. And the same problem is from 2nd to 1st gear. The vehicle makes a loud clunk and it jerks simultaneously. The fact I spent $50,000 on this truck brand new and have got nowhere with the problem is outrageous. I always believe it is a safety concern, because the vehicle will move it radically. When I brought it to my dealership they said it was 'left in 4 wheel drive' ridiculous lies. And if that was the case why did they 'update the transmission computer.' regardless, all of these problems from GM have been swept under the rug. The problem has never stopped. …
Tl* the contact owns a 2017 Chevrolet Silverado. The contact received notification of NHTSA campaign number: 19V645000 (service brakes, hydraulic). The vehicle was taken to uftring Chevrolet (1860 washington rd, washington, il 61571) and repaired under the recall campaign. The contact stated that while driving at 27 MPH, the brake pedal was depressed however, the vehicle independently accelerated with the ABS warning light illuminated. The contact regained control of the vehicle and resumed normal driving. The same dealer was contacted and an appointment was scheduled to have the vehicle diagnosed which was still pending.

I was going north when a vehicle suddenly stopped in front of me. I braked as quickly as possible, the 2014 Chevy Silverado that I was driving only slowly came to a stop. Unfortunately, I rearended another vehicle. Thankfully I had not gotten up to the speed limit (30mph) and was only going 20mph. My truck would not brake quickly. No screeching tires, no black marks on the road. The stop was so slow that I had time to turn the steering wheel and only damage part of my front end. The grill, bumper, and hood were smashed in. No airbags came out of the truck, and my OnStar service sensor did not go off. After colliding with the vehicle my 2014 Chevy shut off by itself. I had the brake still depressed & put the truck into park.
