We have a 2017 explorer with 62k on it. It has the 3.5L TI-VCT V6 Engine. We bought it new and have been very happy with it. After the past 4 oil changes, the vehicle smells like burnt oil. We get our oil changed at the Ford dealer where we purchased it. We have gone back to the dealer with the burnt oil smell complaint. They can smell it too but have been unable to find where it is coming from. The smell will eventually dissipate but it take about three weeks for it to go completely away. The smell is like oil spilled on the exhaust and is really strong. If it happened once we could chalk it up as a minor annoyance, but it now happens every time the oil gets changed. Has anyone out here had a similar experience?
