Collapsible lifter and lift rod failure

An electrical component related to the vehicle's rear sliding glass window and rear defroster malfunctioned and overheated, causing smoke to fill the cabin of the truck as it was being driven down a busy highway. Immediately following the smoke, the rear window violently shattered due to overheating from the malfunction.

This complaint is submitted as additional information related to a previously filed safety complaint for the same vehicle and incident. Since the original submission, General Motors Product Assistance Claims verbally denied responsibility, refused to inspect the vehicle, refused to provide written confirmation of their denial, and ceased responding to emails and calls.

Your engine is making a ticking noise and the check engine light is on due to a bent push rod caused by a failed lifter in the AFM (Active Fuel Management) system — a manufacturing defect. Your mechanic identified this as a known issue affecting 2018-2021 Silverados, but GM has refused warranty coverage and Goodwill assistance despite acknowledging the problem stems from their manufacturing error. Fixing this will require removing the engine valve cover and replacing the bent push rod and failed lifter assembly.

Your truck started shaking abnormally while driving around 60,000 miles, with no warning lights appearing on the dashboard. The shaking suggests a suspension component may be worn or damaged. You'll want to have a mechanic inspect your suspension system to identify and replace the problematic part.

My truck has been into the dealership repeatedly from Aug 2024 to where it sits now to this day because of the engine and the electronic fuel management system. This fuel management system has destroyed my engine by allowing excessive oil consumption to which it turns the oil black. The engine goes from v8 to 4 cylinder to save on fuel which makes the engine work harder.

We bought the truck new 2018 and started having trans issues and leaf springs popping. So, we took back to dealership and all they did was change fluid in trans and pump grease in-between leaf springs. I did get them to finally change passenger side leaf spring out, but that does no good when leaf spring they put on has the same issue.

Transmission is having hard shift and shutter at a speed of 60/65
