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. 2-Mine, my daughter, the semi truck driver, and many other surrounding drivers safety and lives were put at risk. 3- Yes the dealer has confirmed it was a totally engine loss. 4-no one else has inspected the vehicle 5- No light, sensors or warnings just a loud bang then our lives flashing before our eyes.
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.
when entering traffic vehicle wheels locked up and engine stopped, when restarted vehicle was in limp or reduced power mode, check engine light is on, message on screen and in app identifies transmission and electrical problem. anti slip was engaged automatically upon restart.
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.
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 warning light came on the dash saying may not be able to shift soon. I dropped of at the dealer and they said they were backed up on that department I would have to leave it there and they would diagnose in a week and let me know. Still waiting 6.2 zr2
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.
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.
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
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.
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
