2026 Chevrolet Silverado 1500 driver assist problems

FORWARD COLLISION AVOIDANCE: WARNINGS

I purchased this vehicle brand new and have experienced a recurring issue when coming to a stop. The forward sensors activate indicating I am too close to an object (even though nothing is in front of the vehicle), and the engine stalls. Everything shuts off except the driver information screen, which displays the prompt "Shift to Neutral and Press Start Again." Following this prompt does nothing; I have to shift into park and press the ignition again to restart the vehicle. I have taken the truck to the dealership multiple times. After the first two visits yielded no solution, the maintenance team contacted Chevy engineering, and a hard reset was performed. However, today (8/24), a similar issue occurred. While at a complete stop with a full car length between my truck and the vehicle ahead, the sensor warnings activated. The engine did not stall as it had before, but the issue seemed entirely random.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

While using the adaptive cruise on the highway the truck will rapidly slow down as is there is something in it path even though nothing is there. This has happened multiple times on the expressway now and I can no longer use adaptive cruise for fear of what it will try and do.

FORWARD COLLISION AVOIDANCE: WARNINGS

The forward collision warning is excessively sensitive to vehicles and pedestrians. I've had the alert go off recently for something so simple as pulling into a parking spot. It goes off frequently just driving past pedestrians and throughout what I consider to be normal driving where I am not coming close to a collision with a vehicle. It is very unsettling and startling when the alert goes off indicating that I am coming close to a collision with a vehicle or a pedestrian. I had a 2023 Silverado 1500 LT/2.7 Turbomax engine and it was not this sensitive. I fear that this may actually cause an accident at some point or if the emergency braking were to activate with another vehicle behind me.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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
