NHTSA Complaint #11487141 — 2012 CHEVROLET SILVERADO 1500

Oil consumption on 2011 to 2014 Chevy Silverado engine related issues on the 5.3 liter v8 flex fuel engine. Vehicle produced a service engine soon light on 9/27/2022 so I took it to the local Chevy dealer mechanic. They inspect it and determine that it was a misfire in cylinder 7. They went to run it through my warranty that I purchased when I baught the vehicle 2 years ago. They advised that it would not be covered so to it being an oil consumption issue. They advised that to fix the issue permanently it would cost $3,600 to fix. Being that this is a known issue GM should be issuing a recall to correct this. I only have 60000 miles on the vehicle and the engine is basically junk without the fix. I do not have the repair invoice at the this time as it is currently in the shop with the local Chevy dealer The mechanic advised that this is a known issue with all Silverado’s between 2011 and 2014 and that GM knew this was an issue and that eventually the engine will sieze if you don’t have the pistons and rings replaced. This is a country wide problem and appears there is a possible class action lawsuit due to GM knowing this was an issue and in 2014 GM re-engineered the 5.3 vortec to correct this issue. In addition it is a known issue another problem is the rear wheel wells rusting on all Silverado’s. This should also be looked into Thank you for your time and consideration!
