NISSAN issued a recall on the FRONTIER and XTERRA models

On certain four wheel drive vehicles, water may enter the rear axle housing due to inadequate sealing of the ABS sensor in the axle housing. This may result in corrosion and eventually failure of the wheel bearing. If this occurs, the wheel assembly could separate from the vehicle. Correction: Dealer will inspect the rear axle for water intrusion and replace any affected components. The ABS sensor will be resealed to prevent water intrusion.
