Cause 1 (for Symptom 1): Water may accumulate around the touch sensor in the outer handle, resulting in temporary lower sensitivity of the capacitive sensor. Also, if car wash foam gets inside the outer handle while washing the vehicle, the foam may disturb the touch sensor detection. Mazda is still working on a mass production change for this concern. Cause 2 (for Symptom 2): Improper soldering in the production process may disturb the touch sensor detection. To eliminate this concern, the production process has been modified. Customers having this concern should have their vehicle repaired using the following repair procedure. REPAIR PROCEDURE 1. Verify customer concern. 2. Repair the vehicle depending on the experienced symptom(s). Symptom 1: Follow the \"Procedure to waterproof a touch sensor” below to make the touch sensor waterproof.
