Follow-up to the federal safety agency complaint #11659972. On 12/10/2025 at 14,808 miles, under warranty, I brought my 2024 Silverado ZR2 (engine replaced May 2025 under recall 25V‑274) to Paramus Chevrolet for hard shifting, sputtering, severe fuel economy loss and oil leaks. The dealer opened a case with GM, drove it about 214 miles logging data, and sent the data to GM. GM refused to repair it. The truck was returned 12/16/2025 at 15,022 miles unfixed and unsafe; an engine failure at highway speed could kill the driver, passengers and others.

Follow-up to the federal safety agency complaint #11659972. My 2024 Silverado ZR2's 6.2L engine was replaced in May 2025 under recall 25V‑274. Around 13,800-14,000 miles the same symptoms returned: hard shifting, severe loss of fuel economy, sputtering, and the engine leaking oil every time I added more. The truck is unsafe to drive; an engine failure at highway speed could kill the driver, passengers and others. Service scheduled at Paramus Chevrolet for 12/10/2025.

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 days undergoing this high-voltage and chassis teardown.

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

This vehicle is a 2024 Chevrolet Silverado 1500 featuring a 6.2L V8 engine and a 10 speed transmission, currently at 58,136 miles. The vehicle was experiencing a severe shudder. An official GM Technical Assistance Case (TAC) engineering case was opened on July 30, 2026 confirming a verified DFM cylinder deactivation or valve train malfunction. However, on August 21, 2026 the dealership falsified the repair log by printing ‘Concern Not Duplicated’ to the manufacturer, while physically installing an unapproved aftermarket Range Technology DFM Eliminator module into the vehicle’s engine harness to artificially override the factory emissions and cylinder deactivation programming to mask the mechanical failure. This vehicle is part of the active the federal safety agency Engineer Analysis EA26005, and the manufacturer’s dealer network is actively using unapproved third party hardware shortcuts to evade mandatory warranty repairs before the vehicle’s 60,000 mile factory powertrain limit expires. I called GM to report and request a warranty freeze and regional field engineer to go to a different dealership and was told they can’t freeze a warranty because the TAC was closed on August 28, 2026 as resolved even though it was not resolved.

In reference to 2024 Chevrolet pickup, 6.2L engine, 10 speed transmission. The vehicle is available for inspection upon request. I believe the transmission is going into "partial lock-up" at full/highway speed. When traveling on highway with cruise control engaged, the vehicle suddenly acts as though the brakes are being strongly applied, slowing the vehicle at a very rapid rate, down as low as about 40 MPH. The vehicle slows quickly enough that the driver and passengers are thrown forward to the extent allowed by the seat/safety belts. The issue terminates itself at various times. The vehicle has been inspected by GM mechanics several times, but they cannot find the problem. There were no warning lamps, messages, service engine lights, etc. This has occurred on at least five (5) different occasions. The first occasion was at approximately 7000 odometer miles. The vehicle now has 25,100 miles. All incidents have been reported to GM dealership mechanics.
