Hot Burning Smell

[Idaho Red Rocket 3]

Thanks for the responses.
Three cars so far have had burning smells. Yes all at dealers. No PPI yet. Nothing like antifreeze smell. Not like an oil burn smell either. All with manual trans.

1) 2002 S with 72k miles. Strong hot burning smell reminds me of an electrical burn smell but not quit exactly. The more it is driven the stronger the smell. Car had very stiff steering. Heavy in my hand. Can smell in cab with top down at stop lights. Strong smell all around car when finished test drive.

2) 2006 Base with 27k miles. Strong hot burning smell reminds me of a rubber smell but again not quit. Strongest on standing at the right rear fender. But still pungent standing at the left side too.

3) 2006 Base with 35k miles. Faint hot burning smell on left side but stronger on the right. Similar smell as car 2 but not as heavy.
