I was driving with my wife about to merge into traffic on the interstate when I had a huge power loss. It was a busy part of the interstate where I could have been ran over. There was a lot of traffic and was fortunate the Semi driver was alert and slowed down. I was not aware of any failures of this motor or received any notices from GM. After conducting research I found that this was a know issue that GM failed to report. My truck has been serviced regularly and until that point had not given any signs of a upcoming failure, I have read that GM is looking into other years such as 2019 which mine is. I have had no luck with GM customer care with the only response being I need to crunch the numbers from my claim advisor. I have the 6.2 L87 motor and know of the clip failure do to poor assembly and parts and debris getting into the motor causing the failure. I am looking to report this and request any assistance available. My first stop was the dealership, then GM customer care

Transmission jerks, slams, forces a feeling of being rear-ended, delayed acceleration with sudden engagement causing uncontrolled acceleration. I've had it looked at every time I've taken it into the dealership for regular maintenance. They haven't been able to reproduce it as it only happens once, first time after not driving it for a while. No warning lamps or messages ever appear.
