Chevrolet
Silverado

The 8-speed transmission has been a problem from day 1 of owning this truck. It has a bad vibration, slips into gear and hard shifts. I have maintained this truck to the fullest and have done all service to the fluids as requested by the manufacturer. I have never pulled a trailer, and I want The NTHSA to make all Chevrolet products that have this 8-speed transmission recalled. GM should make this right. These vehicles aren't cheap.

The transmission consistently fails to shift properly, hanging between Drive and Overdrive. The dealership initially diagnosed the issue as a faulty torque converter & lines, then a tow/haul switch, and replaced it; however, the failure persists. The transmission now requires full replacement. I believe this is a known manufacturing defect present prior to the vehicle's release. Additionally, the lifetime powertrain warranty originally attached to the vehicle has been removed from GM's records. This hesitation causes unpredictable acceleration and loss of power, creating a significant safety hazard when merging onto highways or navigating heavy traffic. It is available for inspection upon request.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving approximately 45 MPH, there was an abnormal knocking, popping, and rattling sound coming from the engine compartment. The contact stated that without shifting to park(P), the vehicle turned off unintendedly. The contact had not attempted to restart the vehicle. The vehicle was then towed to a dealer, where it was diagnosed, and it was determined that the lifters on the right side of the engine needed to be replaced. The contact stated that the camshaft was possibly replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

During the first transfer case fluid service on a 2019 light-duty 4WD truck equipped with an Autotrac two-speed transfer case, the drained fluid was bright red and consistent with automatic transmission fluid rather than the required GM Auto-Trak II blue/green fluid. The transfer case had never been serviced since new, so the fluid appeared to be the original factory fill. Before the discovery, the vehicle occasionally hesitated when shifting between drive modes and sometimes felt as if the system was binding or briefly locking up during transitions between 2WD, Auto, and 4WD modes. These symptoms were intermittent and no warning lights appeared. Using the wrong fluid in this type of transfer case can affect clutch-pack operation and may cause premature wear or loss of proper torque transfer. The system has now been refilled with the correct fluid, and the drained fluid is available for inspection. The issue has not yet been inspected or confirmed by a dealer.

“2019 Silverado 5.3L – engine knock + oil leak post-warranty install = fire/breakdown risk”

"The vehicle has developed a recurring ticking/knocking noise in the engine, worsening under acceleration, accompanied by excessive oil consumption. This is a repeat issue after a warranty repair on June 6, 2022, where all 8 lifters on the right bank were replaced due to AFM/DFM lifter failure. I believe the current problem is caused by metal debris from the initial failure scoring cylinder walls, rings, and bearings, leading to lower-end damage. GM denied coverage under Special Coverage Adjustment N242498000 despite the prior repair and matching symptoms in bulletin PIP5623. Johnson Motor Sales quoted $14,893.89 for engine replacement. The noise and oil loss pose a safety risk of sudden engine failure or loss of power while driving, potentially causing a crash."

I own a 2019 Chevrolet Silverado 1500. While driving 35 MPH entering the flow of traffic, the vehicle lost power with the engine misfiring. The messages "Service Parking Brake" and "Service ESC" were displayed. The check engine warning light was also illuminated. I drove to the nearest dealership the vehicle was diagnosed that cylinder #5 lifters had collapsed. The dealer informed me that the cylinder lifters needed to be replaced. Additionally, the camshaft would be replaced as necessary. The vehicle was being repaired. The manufacturer will be notified of the failure. The failure mileage was approximately 88,000. and I was informed that my service contract had expired less than 2 months ago
