Component
Electrical system
Summary
Some customers may experience all of following symptoms: The door lock/unlock operation will not work using the remote transmitter button. The door lock/unlock operation will not work using the door lock/release touch sensor. The engine will not start using the ignition switch. This is caused when excess load is applied to the remote transmitter and the electrical terminals in it may be deformed, causing poor contact with the battery. To eliminate this concern, the structure in the remote transmitter has been modified to reduce the deformation of the electrical terminals.

Owners of these vehicles have filed 40 complaints in the electrical category.
