March 24th 2023. our 2021 2.7 turbo silverado 4x4 had lost oil and was leaking, dealership repair oil pan & gasket due to defective. Well today July 2nd 2023 engine light came on, looked under truck same oil leak and no oil on the dipstick. I called for appointment in the morning! I believe it's leaking above the oil pan, but they didn't listen to nothing I said back in March. This is ridiculous not even 45,000 miles and this will be 2 times in 3 months it's had same problem not resolved. Looks like last repair made they just put a ton of gasket sealant all around my pan :( ugh this is unacceptable.
