Burning Rubber Smell After Driving or at High Speed
A burning rubber odor in a 2020 Honda CR-V, especially after driving or at high speeds, often indicates a mechanical issue such as a slipping serpentine belt, a seized pulley, or a dragging brake component. This should be inspected promptly to prevent further damage or fire risk.
Diagnosis Details
Possible Causes
Serpentine belt slipping due to wear, misalignment, or a failing tensioner, causing friction and rubber smell.
Seized or failing accessory pulley (alternator, power steering, AC compressor) causing belt to overheat.
Dragging brake caliper or parking brake not fully releasing, causing brake pad/rotor overheating.
Oil or fluid leak dripping onto hot exhaust components, burning and producing a rubber-like odor.
