I was driving 65mph down the freeway when the truck suddenly turned off and the dash told me to put in neutral and start again so I did just that. Made it about another mile and the truck completely turned off and wouldn’t turn back on there was nowhere to pull over or get off the freeway in that time frame so I was stopped in the middle of the highway with my family in the truck. Luckily a guy in another truck was able to push me over to the shoulder with his vehicle where I sat and waited four hours for a tow to the dealership. Two days later they called me and told me it’s spun a bearing and threw two rods and needed a new engine. I’m anal about servicing my vehicles they told me it just happens, but it was a brand new truck with only 35k miles. Ever since I got the new engine installed it’s constantly squeaking and they can’t seem to pin point the issues I feel like it’s going to happen again and this next time I’ll probably be out of warranty and it’ll be out of pocket for me to fix.

- #11636690January 18, 2025ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
While driving down a major, extremely dangerous highway [XXX] in Pasco County, FL) my truck randomly shut off (with zero warning, no check engine lights, nothing) Thankfully, i was already in the right hand lane and managed to coast into a gas station. At 60, 375 miles on my 2021 truck I was 352 miles outside of the powertrain warranty, so I had my truck towed to the closest chevy dealership to see if they would good-will the warranty. They (Chevy) reported to me that there was a rod-knock with an estimate of $17,203.52 to rebuild the motor. I would also have to pay approximately $2000 (10 hrs of labor) for tear down of motor to even see if GM would POSSIBLY pay out anything on warranty. I am the only owner of this truck since day 1. I have every oil change record that was done as specified by the manufacturer. I have no means of transportation at this time. My truck is available for inspection. I am also unable to take out any other vehicle loans while I am forced to pay for a truck that now, has no motor. Also, I went in for a recall of a software update for the forward collision system. Previous to the dealerships update, the system was working fine. After the update, the collision system no longer works. This is greatly affecting my ability to work, and function as a member of society. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. The automatic tailgate opens by itself randomly. It appears to be malfunctioning. I am unable to open it from the tailgate now. When it’s open it continues to attempt to unlatch making the noise. It’s opened while driving. 2. So far I lost a cooler on the highway due to this problem which would cause a road hazard to other drivers. 3. I brought it to the dealer they said it’s not there problem due to my vin not matching the recall even though there’s a recall for this problem with same year trucks. 4. It has not been inspected due it not being an official recall. 5. No warning lights regarding this issue.

Vehicle has less than 35k miles. Vehicle started and operated normally Attempted to turn onto main thoroughfare from a stop. While still in drive, vehicle engine rev’d up but transmission did not engage. Attempted to cycle through gear selector with same result. Reverse is the only gear that allowed vehicle movement. Serious safety concern if this were to happen while traveling at any significant speed or if trying to merge or cross heavy traffic. Vehicle has not had an official diagnosis, but I believe this is a transmission valve body problem known to the manufacturer. There was no indication prior to this event of any mechanical or electrical problems with the vehicle. This issue could easily get someone killed.

Engine Code P10D9. Electrical harness to the DEF tank melted. My truck was not part of the GM recall but clearly effects more vehicles than they believe. See NHTSA report N212342980. Spoke with Chevy customer service today and they stated the wiring harness melting is not covered under warranty. This is a fire hazard that GM should remedy. The recall is clearly larger than 38,000 vehicles. Are we supposed to drive the vehicles and not know if they will catch fire or not? I spoke with a technician at Milnes Chevy in Imlay city today and he stated that he sees so many of these trucks that were not under the recall having the same issue with melted wiring harness.

When putting vehicle in PARK and releasing the foot brake it rolls back an excessive amount of space sometimes it rolls back so much we begin to get scared thinking we are still in DRIVE and jump back in vehicle just to learn we are in PARK. We have had this issue since the day of getting truck in August of 2024 and how much it rolls back is never consistent on the length of the roll back. Sometimes it feels like it make even slip out of gear and just keeping rolling. It’s very scary and we have almost knocked ourselves out when it happens trying to jump back in to stop it.

The 8-speed automatic transmission (8L90) has been failing. It has put me in my passengers safety at risk because my truck can lurch forward without warning due to delayed downshifting and RPM surge. Yes, the dealership has confirmed this issue multiple times. The component has been inspected by the dealership multiple times. Yes, check engine light came on and yes there was symptoms before the failure such as lurching jerking, surging harsh and erratic shifting. They first appeared at 55,000, MI. It continues to happen to this day. I have an appointment scheduled for today at 9:20 a.m. for the dealership to look at it again but this is a legitimate concern.

On January 6 and 7, 2025, the broken transmission valve body was subjected to inspection by a Chevrolet dealership. The vehicle exhibited faulty gear shifts, which resulted in reduced speeds and triggered the activation of "limp mode." This malfunction occurred while driving under severe winter storm conditions, posing a potential risk for serious injury. The issue was methodically diagnosed and documented for parts replacement. Furthermore, the transmission service indicator activated via the associated application, and the check engine light illuminated alongside a blinking "D" mode indicator at the time the warning lights were activated. The initial signs and symptoms of the issue were first observed at 11:00 PM on January 5, 2025.

Push-button tailgate electrical failure. Tailgate opens on its own while driving and while truck is off. This is a known issue that has already been recalled by GM but my truck was not included in the recall, even though the problem and repair are exactly the same as the currently recalled vehicles. I had to pay a GM Dealership to make the repair as the vehicle was unsafe to drive due to potential for flying debris from the bed while driving.
