This bulletin provides information on replacing the Tire Pressure Monitoring System (TPMS) valve stem cap and/or valve stem on 2017 model year Night edition Tucsons. The aluminium valve cap might corrode onto the valve stem making it difficult to remove the cap to inflate tires or check tire pressure.
