POWER TRAIN

Potential Consequences:

While driving down the highway pulling a trailer the truck started to slow down rapidly. We were able to pull to the side of the road before the truck came to a complete stop on its own. From that point forward, we could not get the truck to move forward even in 4WD. Ended up towing the truck back and a repair shop determined the transmission needed replaced. About 4 months later, we received notice of a recall describing a similar scenario. I submitted the invoice and documentation to GM, but my claim was denied because the codes and symptoms did not match the criteria for the recall.

EXTERIOR LIGHTING

Potential Consequences:

The front left headlamp assembly low beam light unexpectedly began to flicker repetitively until the vehicle was turned off. In addition, the left front turn signal was failed, but an indication of the failed turn signal was not always present. The headlamp assembly was taken in for replacement at a local GMC dealership promptly due to safety concerns of operating the vehicle on public roadways with this condition. The safety of others was at risk due to the strobing effect of the flickering lights and not being able to drive the vehicle during conditions where headlights are necessary. The flickering/strobing condition of the headlamp was highly distractive and puts other drivers are risk. In addition, due to the natural height of the vehicle the cast of the beam is closer to the rear view mirror height of the majority of vehicles. The problem was confirmed by a local GMC dealership and was identified as a faulty headlamp assembly. The vehicle was not inspected by any other party besides the dealer who performed the diagnosis and repair. There were no symptoms of warning messages prior to the failure.

ELECTRICAL SYSTEM

Potential Consequences:

On 11/21/24 noticed passenger headlight day light running light flickering. On 11/22/24 right turn indicator intermittent fast blink, dash message stated turn indicator failure. Once home, inspected passenger headlight assembly. Found DRL, turn signal, and low and high beam head lights were inoperative. On 11/25/24 went to GMC dealer/service. Staff seemed aware of issues and stated they are common, that they carry the $1,400 sealed assebly in stock. Vehicle is 4 months over warranty, but only has 29,000 miles. There is no visible damage to the assembly, but there is visible condensation inside the lens. GM has a published service bulletin, 01-08-42-001P, that specifically addresses this issue for my vehicle. The earliest date the issue could be diagnosed/service date is 12/10/24. A complete failure of this non-servicable headlight assembly is an absolute safety issue. Decreased daytime visability with the loss of one of two Daytime Running Lights, the lose of the front turn indicator to alert other drivers of my intentions, the lose of a set of low and high beam headlights. As mentioned, there assembies are a sealed LED light assembly. If any one of these lights fail, the only remedy is the replacement of the entire unit with a $1,400 part. GM has had multiple recalls of this same issue among their vehicle, but continues to produce the same failing pieces.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Potential Consequences:

I purchased a 2021 GMC Denali 2500 in December 2023. A couple days after purchasing the vehicle I received a message on the dash saying the front camera was not working. I took the vehicle into the dealership where they said they reset the computer and nothing was wrong with the vehicle. One month later I was involved in a collision where a vehicle turned in front of my vehicle and the Automatic Emergency Braking failed to activate. I applied the brakes but due to my delayed reaction time 1.5 seconds, I broadsided the small vehicle with my large truck. Luckily the speed was only 20 mph and no one was hurt or killed. At this time I did not know my vehicle was equipped with AEB. In October I discovered through GM and a different dealership that my vehicle was equipped with Automatic Emergency Braking. I have had several occasions when the AEB including the crash where the AEB should have activated but never did. In 11 months I have never had the AEB activate. I took the vehicle into the dealership where I bought the vehicle and they said their computer said everything was operating correctly. The tech never drove the vehicle where the AEB should have activated. I have driven many cars and even the same model vehicle as mine, so I know what the AEB feels like and my vehicle the AEB is not working. The dealership told me to take the vehicle they checked everything GM told them to check. When I talked to GM they told me to immediately take the truck to the dealership and the dealership did nothing.
