We bought this truck last October. We change the oil frequently to keep it in good
Shape but yesterday we noticed a burning plastic smell coming from the hood. Its more concentrated in the left side. Starts after you drive about 10 minutes. Doesn't heat up. Oils are still good. It has enough antifreeze. Don't what it could be.

 

If you don't know what it could be, nobody here does either. Could be anything. Maybe you drove over a plastic bag and it got sucked up onto the exhaust manifold. Maybe a plastic electrical connection is overheating. Somebody is going to have to very closely inspect the suspected area and sniff this one out.
