  Summary

  This Service Alert provides information for the following symptoms. Although Battery State of Charge (SOC) is full, Maximum Driving Distance Display shows 1 mile (1 km). Although Battery SOC is full, the vehicle cannot drive using EV mode (using electric motor power only) and will use HEV mode (using both electric power and a gas engine. This is caused by low ambient temperature and low battery temperature. EV mode is suspended until the battery warms up to protect it from degradation and the gas engine will power the vehicle. This is normal operation. If the battery pack is able to warm up, EV mode will start and the display will change to show the correct Maximum Driving Distance Display for EV mode.

  Summary

  Some customers may complain that the driver’s side outer mirror glass vibrates when driving at high speeds at approximately 60 mph (100 km/hour ) or more on bumpy roads such as road joints, coarse-grained paved roads or rough roads. This is caused by insufficient hardness of the adhesive tape between the outer mirror glass holder and the mirror glass. To eliminate this concern, the material of the adhesive tape between the outer mirror glass holder and the mirror glass has been improved and the tape location has been modified.

  Manufacturer:

  MAZDA

  Summary

  Some vehicles may exhibit a high-frequency noise from the fuel pump. When the fuel temperature is high, vaporization may occur in the return fuel from the pressure regulator valve assembled on the fuel pump unit. In that situation, the spring in the pressure regulator causes self-excited vibration, resulting in the high-frequency noise. To eliminate this concern, the shape of the pressure regulator valve in the fuel pump has been modified to control self-excited vibration by reducing pressure differences in the valve path.
