2023 Chevrolet Silverado power train problems

“As I was exiting the exit ramp, you could here a noise from the suspension. Then a bunch of smoke came out and there truck seized up and stopped. I got out there was fluid/oil leaking everywhere. There was a trail of fluid following the car down the exit ramp. The truck was telling me to restart but I didn't not due to safety concerns. We had the car towed to the local Chevy dealership where it is being diagnose. There were no warning lights prior or any notification that there was an issue.”

“The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving, the vehicle failed to decelerate properly while the brake pedal was depressed. The brake pedal was firm. The ABS, Emergency Brakes, and Brake warning lights were illuminated. The vehicle was towed to a local dealer where it was diagnosed and confirmed to have a transmission failure. The vehicle was repaired under warranty; however, while driving at approximately 50 MPH, the vehicle was shuddering, and while the transmission was shifting into a lower gear, the vehicle jolted. The same local dealer was contacted. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 58,800.”

“I drive a 2023 Chevrolet Silverado 1500 3.0L Diesel with the 10-speed transmission. The transmission control software failed to monitor/detect valve body wear or trigger a 5th-gear 'limp mode' safety net, resulting in three separate instances of sudden rear-wheel lockup at speed. The dealer was unable to replicate the issue during a service visit from 6/10 - XXX. The issue was raised as the transmission was shifting increasingly badly leading up to this service visit. The first full lockup occurred a few days after receipt of the vehicle on XXX driving eastbound on [XXX]. Off the gas, coasting downhill. Once everybody started speeding up, I increased the throttle gently and the truck shook violently. I initially thought I had been hit by another vehicle but realized it was the transmission. Speed was noted 24 mph. The second incident occurred XXX while traveling to [XXX]. Driving southbound between [XXX] and [XXX] at approximately 50 MPH in a coasting condition. Went to pass a slow vehicle and the vehicle jerked violently an locked the rear wheels. Initial assumption was that I had been hit. Was able to regain control and continue. The third incident…”

“This truck and hundreds, if not thousands of others has many issues with the electronic shifter. Not only do they frequently fail, but Chevrolet does not have any parts available to the dealerships for weeks. These Duramax 3.0 diesel engines are also a huge problem with the emission system and DEF. They constantly fail and we are spending thousands to repair. My truck is stuck at a dealership in [XXX]. I had to rent a vehicle to drive back home to [XXX]. The dealer has no idea how long it will take to get a shifter from Chevy. Is there any help available. Why aren't these shifters under a major recall? I am literally stranded after paying $65,000 for a truck!”

“While operating at highway speeds this truck lost all engine power and would not start back up. Vehicle was towed to local dealer and determined to be a catosrophic failure of the crank shaft. Repairs are being made as covered under warranty.”

“The engine in my 2023 Silverado ZR2 (6.2L L87 V8) failed. It is available for inspection at Rick Hendrick Chevrolet ([XXX]). On XXX at about 67,000 miles, and the days leading up to it, the truck repeatedly struggled to start due to metal on metal contact, almost leaving me and my family stranded multiple times. Driving the vehicle produced a loud rattling noise at 2200 to 2700 rpm, and felt unsafe to drive. Especially with my family. The problem was reproduced and confirmed to be an engine failure by the Rick Hendrick Chevy dealership a week after being dropped off with an appointment. I have been told the engine needs to be replaced under the special coverage program (N252494003). The L87 recall inspection and oil change was completed on XXX also by Rick Hendrick Chevy. There were not warning lights or other symptoms leading up to this engine failure. The symptoms of struggling to start and the ticking noise as 2200 to 2700 RPM started that weekend before I brought to dealership. They got progressively worse. Dealership has said I will receive a new engine under warranty but no timeline for completion. Additionally I have not been furnished with a service…”
