Burning Rubber Smell After Driving or at High Speed
A burning rubber smell after driving or at high speed in a 2020 Ford Explorer typically indicates a component overheating or rubbing. Common causes include a slipping serpentine belt, a stuck brake caliper, or an oil/coolant leak onto a hot exhaust manifold. This issue should be inspected promptly to prevent further damage or a potential fire hazard.
Diagnosis Details
Possible Causes
Slipping or glazed serpentine belt – The belt may be worn, misaligned, or tensioned incorrectly, causing friction and a burning rubber odor, especially after high-speed driving.
Stuck brake caliper or dragging brake – A caliper that does not release fully can cause the brake pad to overheat and produce a burning rubber smell, often noticed after driving.
Oil or coolant leak onto exhaust manifold – A small leak dripping onto hot exhaust components can create a burning smell that mimics rubber, especially after the engine is hot.
