I have an 03 LC with 50k miles-after heavy rain, the front passenger floorboard is sopping wet. Also, the check engine light, and other various electrical icons turn on, and the "P" illuminates while in Drive! Sometimes, the P,R and D all are lit up! Once the car dries out, all lights go away. My dealer told me to replace the windshield, which I have done-twice, but it is still occuring. Also, when the car is in this wet existence, the doors continually "auto lock" every few minutes because the car thinks it is in park, but then must realize it is in drive.
