2025 Chevrolet Silverado 1500 Transmission Problems

Your truck's wheels locked up and the engine shut off while you were entering traffic. When you restarted it, the vehicle went into a reduced power mode with the check engine light on, and your dashboard and app both showed transmission and electrical problems. The anti-slip system also engaged automatically when you restarted. This issue will likely require diagnostic scanning to identify the specific transmission and electrical fault causing the shutdown.

Your truck started lurching and limiting acceleration with a "reduce acceleration" error message while driving normally. The next time you started it, a check engine light appeared and the truck won't shift into reverse, showing a "conditions not correct to shift" error and engaging the parking brake. The truck continues to lurch and limit acceleration, making it unsafe to drive, despite having only 21,000 miles.

Your transmission warning light came on, indicating a potential shifting problem may develop soon. The dealer has your truck but is backed up and can't diagnose it for about a week. This will likely require transmission fluid analysis, filter replacement, or internal transmission service depending on what the diagnostic reveals.

infotainment center and navigation and Bluetooth with phone problem started on the way home from the dealer same day it was purchased , 3.0 diesel engine failed at 7000 miles

Shifting thru lower gears was irregular in lower gears 12/02/2025. Made appointment with dealer on 12/04/2025 they could not duplicate. 12/16/2025 Reverse would not work. Tried to take to dealer and couldn't go over thirty mile per hour without transmission jerking. was towed to dealer on 12/17/2025. it's been there since.

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.

There is a reoccurring issue where vehicle will stop functioning bring up a error to service every component on the vehicle and is completely random when it occurs and dealers have not been able to replicate it after 4 visits

On the evening of August 27, 25, when exiting the highway ramp, the vehicle's engine suddenly stopped and stalled, the gear automatically shifted to neutral, and the hazard lights could not be turned on. After about 2 minutes, it restarted normally and turned on the hazard lights.

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.

when coming to a stop, the truck idols high before slowly going down. Seems unsafe as if is not wanting to stop. I am also hearing a chirping coming from under the hood.

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. After a GM engineer gave the mechanics permission, they dropped the transmission to find that it was completely seized and had also seized the engine, though the engine was reportedly not damaged. The entire transmission was replaced and the truck was returned to me with about a month of downtime. This was a clear safety issue as the truck stopped working while on a highway. Luckily, I was in a heavily populated area where help was available. The transmission was returned to GM for further inspection and the repair was fully covered under warranty. Prior to the incident, there were no warning lights/messages, but only appeared after the issue.
