2018 Chevrolet Silverado 1500

Failed/collapsed lifters associated with known Active Fuel Management (AFM) issues. These issues are documented in Technical Service Bulletins and I believe there are Special Campaigns for 2014-2018 L83 engine, but my VIN does not have a Special Campaign attached to it for some reason. I believe there are also class action lawsuits associated with these known issues, but a recall has not been issued.

Parking brake pad failure has occurred twice. Last month at 31,668 mi, truck was taken in for servicing a warning light due to TPM failure (all replaced), and I asked for parking brake inspection because I was pushing pedal to the floor in order to engage. Mechanic said "Left rear prkg brake shoe has section missing." He had never seen that before and I exclaimed that it happened first in Apr 2021 at 18,770 mi. I am not sure which side it was since it was not written on the service invoice, but I suspect the right side because during a Nov 2021 oil change the invoice included "adjusted rear rh parking brake." OEM replacement pads were installed both times. I have the latest failed pad which shows about 2 in of material missing from the shoe substrate, not the 2021. Kearny Mesa Chevy repaired this in 2021; Walt's Danville Service in 2026. No safety issue, but could have been a problem in event of brake failure an need to stop vehicle by applying parking brake that would not hold. I asked KMChevy if this should be a warranty repair or a recall issue and they refused to consider in 2021. It cannot be coincidence that this happened to Chevy OEM equipment, I suspect to both sides. I paid ~$500 each time and feel that Chevy corporate should compensate me.

We purchased a 2018 Fully Loaded Chevy Silverado LTZ/Z71 ($60,000) in 2019, with the idea it would last. After being super meticulous with maintenance and keeping this vehicle in top condition, we just passed the 110,000 mile mark. I have receipts of all the work/maintenance completed on this vehicle. I began to hear a ticking noise in the engine block, and the check engine light came on, so I pulled the codes and went to a local transmission/engine mechanic to find that I have a bent push rod (manufacture failure) due a failed lifter/AFM system. I opted not to take it directly to the dealer as they charge $179 base rate for diagnosis which could increase depending on the diagnosis needed. After numerous calls, I found this is a very common ($7,500-$11,000+) issue with '18-'21 models. Explored my options only to find the 2021- 2026 engines are worse with issues involving crankshaft, engine seizures and an active lawsuit with the new 6.2L V8 engines. (Silverado, GMC Sierra, Tahoe, Suburban, Yukons) I was then pointed in the direction of speaking to the GM Manufacture directly, again. I had contacted them numerous times and was told the damages, even though are not preventable and are directly due to a manufacture error. I was told I must take my vehicle to a licensed service dealer to be diagnosed. I informed them, that I was already told my vehicle would not be covered so I did not feel the need to endure additional cost only to be told the cost would again, not be covered. I'm not seeking full payment; I even mentioned Goodwill assistance of which they denied; however, I'm without a vehicle and have received very little to no communication in resolving this issue, which is an issue I'm finding is happening to many others alike and General Motors Corp, is not taking any responsibility or accountability in this matter.

My transmission failed at around 69,000 miles. This was confirmed by the dealership. I bought my vehicle from and was covered under warranty. I purchased my vehicle in 2019 from a Dodge dealership and it came with a 10 year hundred thousand mile warranty for the powertrain. The tech indicated that the torque converter failed sending metal fragments through the transmission, coolant lines and transmission cooler. There were no warning indicators only hard shifting clunking when shifting and shuttering at different speeds.
