Automatic Emergency Braking problems of the 2026 Chevrolet Silverado 1500

While driving my truck returning from a camping trip I received the following warnings in the dash: service esc, service traction control, forward collision system unavailable. Check engine light was flashing. I made the assumption that the check engine light was due to the warnings listed above. I continued to drive the vehicle until I began to feel a very noticeable shudder at idle, at low speeds, and also loss of power at higher speeds. The truck has the 5. 3 ecotec engine with dfm. After researching the symptoms, I found that these symptoms are identical to the know lifter problem with that engine. The truck is a 2026 Chevrolet silverado trail boss with approx. 3454 miles on it. It's currently at the dealership waiting for them to "diagnose" the problem. I was told that it may just be a "faulty sensor", but after reading other people's experience with this engine I believe that the real problem is a damaged lifter/lifter pin due to the poor design and engineering of the dfm system.

I suspect the automatic emergency braking suddenly activated while backing into my driveway. The truck abruptly stopped as if I crashed into something. The driveway was completely empty there was no reason for the vehicle to activate that system if that's even what happened. The dealer was no help I figuring out the issue they made no attempt to even try and diagnose it. I've since deactivated automatic emergency cross traffic braking and it has not happened since.
