Open the full vehicle complaint log (all categories)Cracked cylinder head requiring full engine replacement at ~80,000 miles. Out of warranty. This is one of two vehicles, purchased at the same time from same dealer in 6/2021 with the same engine failure at ~80,000. Second vehicle is [XXX] . It is likely that these two vehicles came off the assembly line fairly close to each other, during covid and all the issues that that brought to supply chains and manufacturing. One I could have chalked up to bad luck. Two is just too much of a coincidence to believe that there isn't something wrong with these engines.

Engine oil leak at the oil filter. The oil filter monting surface has a defect (not flat) allowing oil to push out. It is currently available for inspection, but it is scheduled to been seen by the dealer to be replaced under warranty. Safety - issue was noticed before enough damage was done to be unsafe. The leak was substantial, so I imagine it would lead to a safety issue due to abrupt engine failure. Oil filter was properly installed, verified by independent repair facility. Leak was reproduced / verified by independant repair facility. No warning indicators for the issue.
