This is an extremely common issue and needs to be addressed. Poor quality sealant was used and we weee never issued a fix from the manufacturer. Just told to fix it by paying over $2000 for an issue that the manufacturer caused.

Oil leaking from the engine on the driver side is a safety hazard.
Hopefully this gets addressed.
