2025 Chevrolet Silverado 1500 Transmission Problems

Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2025 Chevrolet Silverado 1500 owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the vehicle was stalling. The message "Transmission Service" was displayed on the instrument panel. The dealer was contacted and diagnosed the failure as a shifter assembly failure. The vehicle was not repaired because the part was not available. The manufacturer was not made aware of the failure. The failure mileage was approximately 15,000.

My 2025 Certified Pre-owned, 10 day old truck with approx. 6200 miles, was parked and I was unable to shift into reverse (as if in neutral). I put the truck in drive and entered the highway. About half a mile later, multiple warning lights appeared and the truck slowed, unable to shift out of gear. Luckily, there was a dealership a few miles away so I drove the truck there slowly and on the shoulder as much as possible. Upon inspection at the dealership, they told me that the valve body needed to be replaced. After the repair, which only took a few days, the dealership was test-driving the truck when the powertrain completely seized. They attempted to restart the truck but burned out the starter and fuse block which was also replaced. …

while driving down the freeway at 80 mph, in my 2025 Chevy truck with 6000 mikes , the truck suddenly locked up, almost throwing myself and my daughter into the dash, thank goodness the semi truck behind us was paying attention of we would be dead! I was able to steer it to the shoulder of the road where I unhooked the battery hoping to reset the system to no avail. Waited on the side of the road till the tow truck got there. towed the truck to my local Chevy dealer where they confirmed the engine was blown, I want Chevy to do a buyback on the truck as I have zero confidence in the truck, do not feel safe in it anymore, my daughter swore to never set foot in it again after such a dramatic event. i now have to wait a month for the dealer to install a new motor, at which time they will not give me a loaner truck, very disappointing. 1-Total engine failure. …

My truck (2025 Chevy Silverado Trail Boss LZ0 Duramax 3.0l) started to have problems when driving. At a stop light, I started to accelerate at about 2000-3000 RPM. While doing so, there was a loud ticking/grinding noise coming from the transmission/Bell housing area. On June 2nd, I dropped the truck off with the dealership. I didn't hear back from them until about a month later (July 3rd) and when I did they said the technician confirmed I needed a new 'axle actuator'. About a week and a half later, they said it did not fix the issue and started to become more of a problem to where they will need an "engine technician" to see if I need a new engine due to the "crank shaft thrust bearing". The advisor said he will call me on Wednesday, July 15th to update me on what I will need. …

Purchased new and after 3 weeks (about 600 miles) I was on highway between 60-70 MPH truck started to shutter like it was losing power and would not accelerate. I complained to the sales person and he stated it ran a little rough when purchased first day - I was told it just needs to warm up. Took truck to dealer and they determined at this time it was a misfire and lifter bank issue. There seems to be an issue widespread - I am not comfortable with car and if on the highway i am not able to accelerate properly or becomes unreliable at the time to accelerate I am worried about safety.

I was driving under normal conditions and the vehicle began lurching, limiting acceleration, with an error saying "reduce acceleration". Was able to get home but the next time the truck was started there was a check engine light and the vehicle was unable to shift into reverse gear. When attempting to put it into reverse, it gives the error "conditions not correct to shift" and turn on the parking break. Trying to drive it with this issue is unsafe. The truck will lurch, limit acceleration, and overall not safe to drive. The truck only has 21k miles on it.

Transmission would not engage reverse gear. Then forward drive gears hard shift and surging. Truck delivered to dealer, inspection revealed a bad valve body. Parts availability unknown. No warning lights or caution lights. Just broke in a parking garage in Aspen Co. I live in south Texas. Truck and travel trailer in Colorado. Truck has 16000 miles. Had this failed two days before we would have been on pikes peak mountain. And the danger of transmission failure going up or down the mountain would have been very dangerous.

Leased a 2025 Chevy Silverado in late 2025. On June 13th 2026 driving home my vehicle all of a sudden had very little power, check engine light went on and thankfully I was at my driveway. Pulled into my residence, shut truck off and called the dealer I leased the truck from at 1:00 pm Satuarday, June 13th. They set me up with a loaner vehicle. I called for a tow truck Monday the June 15th and had truck delivered to dealership. Ive been told, they are looking into? Beyond that, nothing more.

While driving on the freeway with my family in the middle of a snowstorm, my 2025 Silverado 1500 with 8,000 miles on it, suddenly dropped gears down to 1st without warning. The check engine light went on and I later found out it was the valve body that caused it. This could have cause serious harm to my family had I not maintained control of the vehicle. The dealership fixed the problem only for it to happen again a month later. The truck is still in the shop.

Violent shuddering, as if vehicle does not know what gear to be in. unpredictable harsh and delayed gear changes. Many repairs have been made, including transmission replacement, but issue still remains. Newberg Chevrolet dealership that did all previous repairs has denied to schedule an appointment for follow up diagnosis and needed repairs. This shuddering vehicle is unpredictable and unsafe to drive, yet GM has refused to help.
