2014 Chevrolet Silverado 1500: sudden loss of power

Filed Jul 9, 2026 · Engine · SD

While driving, the vehicle suddenly developed a severe, loud mechanical ticking noise from the engine compartment, immediately followed by a drastic loss of engine power and violent vehicle shaking. The vehicle experienced an active cylinder misfire caused by a failure within the Active Fuel Management (AFM) system, where a cylinder deactivation lifter collapsed and became stuck.This mechanical failure creates an extreme safety hazard. The sudden drop in throttle response, engine stuttering, and loss of power impair my ability to maintain highway speeds, merge safely, or accelerate away from oncoming traffic. The engine stumbles significantly under load, risking a rear-end collision on public roads. The vehicle remains unrepaired at this time due to the catastrophic nature of the valvetrain defect and the severe risk of complete engine seizure while in motion. General Motors has failed to issue a safety recall for this known structural valvetrain defect, which poses an immediate hazard to drivers on the road.

I own a 2015 Chevrolet Silverado equipped with a GM V8 engine that experienced significant engine failure symptoms consistent with known GM engine defect issues and related recall/service campaign concerns. Prior to failure, the vehicle began exhibiting abnormal engine noises, warning lights, performance issues, and symptoms indicating internal engine damage. The condition worsened and resulted in major engine failure requiring extensive repair or engine replacement. The failure created safety concerns due to the potential for sudden loss of power and loss of propulsion while driving. Based on the symptoms, model year, and engine configuration, I believe the failure may be related to known GM engine issues involving internal engine components, lifter failures, AFM/DOD system failures, bearing damage, or related defects that have been the subject of recalls, special coverage adjustments, technical service bulletins, or investigations affecting GM trucks and SUVs. I believe the vehicle should qualify for coverage, repair assistance, recall-related repairs, or special policy consideration from General Motors due to the nature of the engine failure and the known history of similar failures affecting comparable GM vehicles. I am requesting that GM review the vehicle history, diagnostics, and failure condition to determine eligibility for recall coverage, special coverage adjustment, warranty assistance, or reimbursement related to the engine failure.

Vehicle is experiencing intermittent electrical issues, including vehicle completely shutting off while driving, driver window security warning message appears, radio, outside temp and fuel economy will reset when starting the truck. Last time it shut down while coming to a stop, a message appeared on the driver information screen saying “3 key programmed to vehicle”. Sometimes before it shuts down while driving, the radio and dash lights go out followed by engine stalling and there are different messages that appear briefly, like, service stabilitrac, roll driver window down & 3 keys programmed. The truck has shut down on me while operating 7 times in the last 3 months! This is EXTREMELY dangerous as i lose power steering & brakes! It has happened while in the middle of a busy intersection, in a round about, pulling into a parking spot, driveway and while driving straight on a road. I have cleaned & checked all ground locations, replaced the battery and alternator, cleaned battery terminals and Cables, checked all the fuses and nothing has made it stop!

I am writing to report a significant mechanical failure with my 2014 Chevrolet Silverado, which I believe warrants further attention due to its potential safety implications and its connection to a widely documented defect affecting many GM vehicles equipped with Active Fuel Management (AFM) systems. The engine suffered lifter and camshaft failure. This is a well-known problem with GM trucks using AFM systems and can pose a safety hazard, particularly if the vehicle stalls while driving. Failed Component: The engine’s valve lifters and camshaft failed. The components and repair documentation are available for inspection upon request. Safety Risk: This failure caused loss of power while driving, creating a risk of stalling in traffic, which could endanger both myself and other drivers on the road. Confirmed Diagnosis: The issue was confirmed by the dealership where I service my truck, Team Chevrolet in Las Vegas, NV. They identified the lifter and camshaft failure as the source of the symptoms. Inspection History: The vehicle has been inspected and diagnosed by the repair facility. I reported my concerns directly to General Motors and formally requested goodwill assistance and an extended warranty to cover the repairs. However, GM denied my goodwill and extended warranty request despite widespread reports and TSBs. Warning Signs: These warning signs began to show June, 2025 after picking it up from the service department at Team Chevrolet as it had been serviced. The truck was taken back to the dealership within 30 minutes of picking it up.

The transmission at less then 150,000 miles grinds and causes a vibration through the steering wheel. It is available for inspection if need be. There was no sign of this failure before it happened. It has made the truck unsafe to operate because of it were to fail it would cause a complete loss of power to the drive shaft, and currently is causing intermittent power loss to the drive shaft. It has been inspected by a local Chevrolet dealership as well as an independent transmission shop that both confirmed the torque converter has begun to fail. The local dealership as well as the transmission shop have both stated they have had a large number of trucks with the same issue come in over the last year. The service manager at the dealership even informed me that there should be a recall put out for the issue. I have even put in a complaint to GM and there was nothing done about the issue. I went back and forth with them for months
