| Mar 2025 | POWER TRAIN | Transmission started fluttering around 60k miles. Per GMC Dealer - this is due to water getting into transmission from fluid put in at the factory.

| Mar 2025 | ENGINE | The truck had been parked for about 4 hours, after a 250 mile trip. I cranked it and started driving to return home. I heard an intermittent squealing noise while driving. I had driven only about 2 miles when the engine suddenly shut down in heavy traffic on a four lane divided highway. I managed to get the truck into the median and stop. I was left stranded in the middle of the highway. It turns out the the engine bearing went bad and ruined the engine. I will now have to replace the engine at a cost of about $15,000.00.

| Mar 2025 | ENGINE | I was driving down [XXX] near Harrisburg PA in an active construction zone when the truck shut off, the dash blinked a few things very rapidly then went black. I was barely able to coast to an area large enough to get my truck out of the highway traffic. I was stranded on the side of the highway for 4 hrs and due to the construction hardly able to get out of the truck safely as it was around a bend. I’ve had to have the truck towed to a few mechanics to learn that it has suffered a catastrophic engine failure as all cylinders have lost compression. It made no noise at all. There was no signs this was going to happen, just driving normally then a complete engine failure resulting in no compression in all 8 cylinders with no noise.

| Mar 2025 | SERVICE BRAKES,ENGINE | I was traveling north on interstate 95 and approaching my exit ramp. I was initially in the inside lane of travel. I accelerated to merge into the outside lane, between two other vehicles, and then onto the exit ramp. Once on the exit ramp, I let off of the throttle and the engine suddenly shut down. I noticed a message on driver information center instructing me to shift the vehicle into neutral and press "start again". The engine had shut down without any warning whatsoever. I complied with the instructions to no avail. The truck is over half full of fuel. I was within an hour of home after completing an approximately 8 hour, 500 mile, round trip over 2 days of driving. After this event, I connected an OBD2 scanner and the only code found was P25A2 brake system control module. I placed the truck in park and tried repeatedly to start the engine. It would not turn over, crank or start. I had power to all systems and no other codes. I had to have the truck towed from the scene. The truck's performance had previously been flawless during this entire trip and had given me no warning whatsoever of the sudden engine shutdown. This is extremely dangerous and a safety concern. | Crash: No Fire: No | Unknown |

Suddenly, the dashboard displayed a message indicating "Low Oil Pressure" and instructed me to turn off the vehicle. There were no preceding alerts, such as check engine lights or low oil pressure indicators.

When I tried to slow down the power assist was gone on the brakes, I had a little braking when I pushed the pedal all the way to the floor as hard as i could, when I went to turn the wheel was hard to turn. I have had no issues like this before. After I managed to stop and turn off then on the vehicle everything came back expect for a warning to service the trailer brakes and the check engine light was still on. It all cleared after a few more restarts. I got the truck to the dealer 4 days later and they said it was the battery going bad even though I was not having any problem starting the vehicle, I had them replace the battery. I am unsure if the problem is resolved, time will tell.
