Purchased Truck in 2019 - 2 weeks after purchase the truck gave a Code and started to stall while in motion. We took into dealership and they did a complete review. They discovered and documented the following: Removed transmission fluid pump and disassembled to inspect- found a large piece of manufacturing metal flashing - that got stuck in valve bore preventing full movement etc. we kept up on all of our maintenance oil changes. We had the transmission flushed just near the end of the warranty as they recommended it. Shortly after, we started experiencing the same issue. Per the dealership, no recalls for this. The power would completely shut down while driving. Took to dealerships, now telling us we need new transmission $12,000 and is the reason for the power shutting down. They are saying GM will offer us $2,000. We feel this is all due to the flushing and maybe having particles from the flushing,
My 2019 Chevrolet Silverado 1500 with the 5.3L engine developed a severe tick, misfire, and rough idle at only 93,000 miles. This was diagnosed as a collapsed AFM lifter on Cylinder 2. GM 5.3L AFM lifter failure is extremely common in these trucks and causes sudden loss of power, misfires, and unsafe driving conditions. This is a known widespread defect, yet GM has not issued a recall. The failure happened without warning and required major engine disassembly. This should be investigated as a safety and reliability issue.
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.
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.

When driving normal speeds to work on a county road, engine light comes on, service light comes on. There was a tapping noise and reduced power. Luckily, there was a sports field parking lot that I could pull into to get out of traffic. We had the truck towed to our house through our roadside assistance program so that we could determine what to do. If we had not been able to pull off the road as quickly as we did, we probably would have been hit by the semi that was barreling behind us. The truck had reduced power.
Truck lost power and began to shake while on the interstate traveling at 75 mph. The check engine light came on. The screen also displayed a message to service the ESC system and the parking brake system. The truck has been maintained at the recommended service intervals. The dealership said the lifters needed to be replaced as well as the electronic brake control module. With a cost of over $8000. The truck has 108,000 miles on it.
The 6.2 Eco tech V8 is failing. Chevrolet new car of Lowell Massachusetts reports that motor needs to be torn down due to component failure. Also transmission is whining and will need replacement transmission shifts hard between gears and lunges forward while down shifting.
Was driving on the highway, heard loud bang followed by a violent metal-on-metal slapping or knocking sound, and a sudden loss of engine power. Came to find it was crankshaft/connecting rod issue that is common in these vehicles. Have a picture of the broken rod and am waiting the get it repaired.
GM know about the problem they are having with there L90 transmission. I did what they recommended. Had the dealer flush 3 times. It's only a temporary fix until the warranty runs out. That's why they changed there warranty to 5 years 60000. Now a few months later the shifting hard is back and now shuttering hard. I drive a lot of highway and a little nurvise of something happening. I only have 63000 miles on my 2019 Chevy Silverado.
The transmission failed at 100,000 miles and the engine failed at 130,000 miles. Available for inspection. Yes the dealer confirmed both failures. No warnings. Immediate failure with engine light. Barely made it home with the transmission and the engine just stopped out of nowhere due to the dynamic fuel management system and oil consumption starvation.
I have been hearing noise coming from the rear of the engine or front of the transmission. I took it to my local shop and they said it appears to be coming from the transmission and that I should take it to a Chevrolet shop because their is a service bulletin (PIP5996A) that describe what I am experiencing. They gave me a copy of the service bulletin and it covers many models and years of the Silverado. I called to make an appointment with Chevy and they said my Silverado is not associated with any recall, so this service bulletin does not apply. I don't understand how it does not apply when my make and year is listed on the service bulletin.
