NHTSA Complaint #11608370 — 2018 FORD F-150

The 2-piece oil pan system leaks. On Ford’s 3.5L V6 motor, a two piece oil pan is known for commonly leaking. The source of the leak is between the plastic oil pan and the aluminum upper oil pan. Over time with the oil heating and coiling this causes the pans to heat and expand at different rates causing gasket failure around the attachment bolts. This is extremely common among these motors. The safety of the at risk operators and passengers comes into play when you consider the oil leak is captured by a steal skid plate where the oil accumulates over time. If enough oil is present and enough heat from the exhaust reaches the waist oil, a fire could start. The only way a vehicle owner would know there is a leak is if they do their own maintenance or have a good mechanic that does the oil changes. The skid plate captures the oil and prevents it from reaching the ground where a puddle would be noticed. This issue has been known and a repair process is put out by Ford already due to the number of issues with this. My vehicle has not been inspected No warning lamps are illuminated. I notice the leak when doing my own vehicle maintenance. It took me a while, but I was able to trace the leak back to the mounting bolts and researching the problem confirmed my suspicions.
