So some of u may remember I had an engine failure at 380 miles on my 2014 z51 manual. I never was informed as to the mode of failure of that engine but the engine was replaced and broken in gently. Last Friday as I was following a Porsche the temp warning came on, oil pressure dropped to zero and engine started knocking and it died. Had the oil changed to mobil one a week before. 1.5 hours after failure there was NO oil on the dip stick. Car was towed to local dealership southern Jersey. They called me initially to say no oil in car then 5 minutes later said they drained 8 quarts. Diagnostics reportedly said engine "came apart" at 60mph. So now I have a rental the car is at a dealership 150 miles from my home. Roadside assistance tells me the dealership has voided my warranty (which they deny) and it would cost me hundreds of dollars to tow to local dealership that changed the engine the first time. The dealership won't touch the car until Chevy tells then it's a warranty issue and Chevy not going to look at the car till Monday. I was not raciing the car but doing a driver's event at track. Local Chevy dealership filled out mechanical clearance paper work for the event. The Chevy customer car person has a call scheduled with me tomorrow and has not answered my voice mail. Looking for thoughts and suggestions. Last time things got very heated on this thread so let's keep it civil and on topic please. Just looking for some assistance with a really bad situation
