2024 Chevrolet Silverado power train problems

“Conditions: Night, Raining, apx 50*F. Traveling on the highway apx 70 MPH with a loaded 18ft enclosed trailer (within the advertised towing limits of the truck). I accelerated to pass a tractor trailer. the transmission attempted to downshift, resulting in a loud bang and shudder. I attempted to accelerate once more. This time the transmission tried to shift, the rear wheels stopped turning for a second or two, resulting in a slide and requiring steering input to maintain the vehicle traveling straight. The rear wheels unlocked and began turning again. I coasted down to apx 55mph and attempted to maintain a lower speed until the next exit. While trying to maintain a safe speed for surrounding traffic, the transmission attempted to downshift. This time resulting in apx 4-6 seconds of the rear wheels stopping and skidding, resulting in a slide situation requiring steering input to remain in control of the truck/ trailer while the rear tires slid. I stopped on the shoulder, locked the truck into gears no higher than 4th gear and drove to the nearest dealer without further issues.”

“Driving down interstate about 65 the light on dash came on stated low engine oil stop engine at same time could smell smoke and saw smoke coming from under hood. I pulled over as fast as I could and by that time the smoke was pouring out from under hood. I turned engine off and I popped hood got out and slowly opened in case was on fire. It was not but I saw oil all over my engine and dripping from under vehicle. The front tire was covered with oil as well as down side of my truck. I saw where I pulled over a long oil streak. Oil kept leaking oil and large puddle formed under engine on side of road.”

“While operating the vehicle, the front electric drive motor suffered a failure, triggering reduced propulsion warnings and rendering the primary electric powertrain inoperable. The vehicle was towed to an authorized GM dealership service center, where the defect was confirmed. To replace the failed front drive unit, technicians had to drop the front subframe cradle and completely dismantle the front suspension and steering assembly. During inspection of the disassembled components, severe mechanical galling and metal scoring were documented on the cast aluminum front steering knuckle mounting boss. Reinstalling suspension and steering hardware against structurally compromised, gouged aluminum presents a severe safety hazard of metal fatigue, stress fracture, or joint failure under dynamic loads. This vehicle is factory-rated to tow heavy loads. Dynamic cyclic forces transferred through a compromised front knuckle assembly—particularly when towing on a weight-distribution hitch—create an acute risk of structural failure and loss of directional control at highway speeds. The vehicle has remained grounded and out of service at the dealership for over 50 continuous…”

“Got my truck back yesterday from in shop for 2 weeks from being repaired. Got to red light just stopped my engine shuts off. Dash shows engine/transmission problems. Exact same thing happened two weeks ago. Had to get towed into dealer again this am”

“2024 Silverado 3.0 Rst turbo replacement, followed by engine replacement at 80K miles. Advised the dealership about the transmission at about 85k miles. At 103,000 miles the transmission failed. GM is denying any responbility. This is already a known issue yet GM keeps denying it. Major saftey issue from the beggining of the purchase. Every complaint has been noted by the dealership.”

“from a stop during fast acceleration made a left turn and rear section or rear axle sounded like it went over a speed bump or wheels locked up, then transmission felt like it was in high gear, did not want to move , or very slowly , i accelerated rpm was 2k or 3k still moving very slowly, this was in heavy traffic. I notice that check engine light went on with TC, parking brake service , some pad lock ( dont know what the ped lock is). 2nd time this happen the parking light service light went on and the brakes locked up again in traffic. 0”
