2019 Chevrolet Silverado 1500

Third transmission failure in 10 months on this vehicle (8-speed automatic). (1) Oct 2025, 67,885 miles: transmission shuddering; dealer replaced the complete transmission with a GM remanufactured unit under extended warranty (RO 240481, Nucar Lannan Chevrolet of Woburn, MA). (2) Jul 2026, 82,439 miles: vehicle would not shift on the highway while driving; DTC P2824 stored; dealer replaced the transmission valve body under warranty (RO 248929). (3) Aug 3, 2026, approx. 82,500 miles — three days after the valve body repair was returned to me — the transmission locked up and the vehicle would not shift gears while in traffic. Loss of gear engagement while driving creates risk of a crash from sudden loss of propulsion. Vehicle is back at the dealership now for the third repair. This vehicle's 8-speed transmission (8L90/8L45 family) is the subject of known shudder/valve-body defect litigation covering 2015–2019 Silverado models.

Vehicle lost power assist to steering without warning.Very difficult to drive vehicle safely once that happened

At 70,000 miles the engine failed. Dealership said it was due to the current issues with the 6.2 motors but mine was not included in the recall but was being evaluated to be part of the recall so I did have to buy a new engine.

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission and drivetrain system appear to be defective. The vehicle repeatedly experiences hard shifting, transmission shudder, hesitation during acceleration, delayed engagement when shifting into gear, and erratic gear changes. These problems occur during normal driving and have progressively worsened over time. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The transmission hesitation and delayed acceleration create a serious safety hazard. When pulling into traffic, crossing intersections, or changing lanes, the vehicle does not respond immediately when the accelerator is pressed. The delay leaves the vehicle exposed to oncoming traffic and increases the risk of a collision. The hard shifting and shuddering also cause the vehicle to behave unpredictably, reducing driver confidence and making it unsafe to operate in normal traffic conditions. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem is consistently reproducible during everyday driving. The transmission shudders, hesitates, and shifts harshly on a regular basis. Although the condition is intermittent in severity, it occurs frequently enough to create ongoing safety concerns. At this time, the vehicle has not been inspected by police or insurance representatives. The vehicle remains available for inspection. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? The first symptoms were occasional hard shifts and slight hesitation during acceleration. Over time, the condition worsened, progressing to severe shuddering, delayed acceleration, and increasingly harsh gear changes. No warning lights or diagnostic messages appeared when the symptoms first began, making it difficult to identify the problem before it be

I was driving the vehicle and suddenly there was a loss of power and a ticking noise. I was up to date with my oil changes per dealer recommendations. Had the vehicle towed to to Chevy dealer and they said they weren’t able to find what the problem is without further diagnosing. Further diagnosing was estimated to be about $2500. I had it towed to an independent shop, Viking Motorsports, to which the owner/mechanic tore down the engine and deemed it as bearing failure in my 6.2 L87. There was no warning whatsoever, just went from running to engine dead immediately. I proceeded to an engine change that has costed me approximately $15,000 and would like full reimbursement if not partial reimbursement from GM given that this is a known issue for the problem. I did not go with the Chevy Dealership for the job since they quoted me $20,000+ for the engine swap and realistically that wouldn’t make financial sense. I have a High Country and at 102,000 miles when the engine has failed. This has put me in such a financial bind.

Wife was driving on the interstate when the vehicle revved up and then a loss of power. had to drive home while vehicle was popping and still loss of power. I took to an Independent Service Center, and they started a tune up with changing plugs. They checked vehicle and advised that it was possibly a lifter failure, but they couldn't fix it. I took to another independent service person and after a diagnostic check and looking into the engine it was confirmed it was a lifter issue. Vehicle has been in the shop for 3 weeks waiting on parts.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle lost power and stalled in the middle of the road. The check engine warning light was illuminated with the message "Fuel Low" displayed. The vehicle was pushed to the side of the road, and the contact later returned to the vehicle and added a small amount of fuel to the fuel tank. After starting the vehicle, the vehicle operated normally and was driven to the residence and parked. The following day, the vehicle was started, and the fuel gauge indicated that the fuel tank was half full. The vehicle was driven to the local dealer, who diagnosed the vehicle with fuel pump power control module failure. The contact was informed that the fuel pump power control module needed to be replaced. The fuel pump power control module was replaced. The cause of the failure was not yet determined. The manufacturer was not contacted. The failure mileage was 71,969.

The engine malfunctioned then the engine light came on. I finally got home turned it off and let cool down. Tried to restart and same issue
