Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.

The module that operates the power window and lock switches can allow moisture in, causing corrosion that can lead to a short circuit. This results in window and lock functions not working, and creates a fire risk. Dealers will inspect and replace affected modules free of charge to resolve the concern.
