Hi, sorry for the wait. My name is***** battery compartment underneath the passenger seat should be inspected for water intrusion. When water leaks into the front of the car it winds up filling the battery compartment and shorting out modules in the compartment. Any modules that have water intrusion will most likely need to be replaced. Water can enter through the sunroof drain hoses or the front cowl area. The roof drains and the cowl should be checked for proper drainage. Water can also intrude into the cargo area and wet the rear signal acquisition module. The rear module is located underneath the rear fuse box. It should also be inspected for water intrusion.

Let me know if you have any questions.
