Without being there to smell the burning rubber smell from your car while it's driving it can be hard to tell exactly what is causing the burning rubber smell from your vehicle.
Sometimes a burning rubber smell can be caused by a tire rubbing something when it's going down the road or your serpentine belt could be slipping on a pulley.
When I had a burning rubber smell coming from my car one day when driving down the road it turned out to be a serpentine belt idler pulley had stuck because of a stuck bearing and the belt would go around the pulley causing the burning rubber smell.
I had to replace the serpentine belt idler pulleys and serpentine belt as well.
The serpentine belt is made of rubber so it can cause a burning rubber smell.
Your brakes can also cause a burning rubber smell even though the brakes are not made of rubber so check that as well.
Oil leaking onto hot exhaust can also emit a burning rubber smell if you're not used to smelling oil.
