I have about 5500 miles on our '11 V8 Overland and I keep getting a burning smell when the engine is under a load. Normal day to day driving everything is fine. However if I tow my boat or accelerate hard I get a burning smell inside the cabin. It doesn't matter if I have the windows open or closed or if the AC is on or not, I get the burning smell. I've mentioned it to the dealer and they just look at me with a clueless look. Then again, they look at me like that every time I talk to them. Clueless. Anyone else experience this?
