One problem related to brake sensor has been reported for the 2004 Nissan Crew. The most recently reported issues are listed below.
While driving at approx. Speed of 30 mph and applying brakes there was a scraping noise and light braking. I traveled approx. 1 mile further and applied brakes with little braking action and scraping noise heard again. Turned engine off and checked vehicle. Re-started engine and all function appeared normal. A week later same action accrued again. I took vehicle to dealership where the abs system was found to be bad. Replaced delta stokes sensor and reprogrammed ecu.
