Hi, I recently purchased 2009 RDX with about 75K miles. the car is fun to drive. The problem I'm experiencing is the car stall/turn off while in drive gear stopping at the signal light. This only happens when it's raining or the road is wet. Any help to diagnose and fix the issue is appreciated. Thanks.

 

First thing I would check is your engine air filter. It it's really old/dirty, that extra moisture in the air may be restricting it too much. I think that's not likely, but it takes 2 minutes to check. After that, and probably more likely, check your spark plug coils. If they are cracked slightly, water could be getting on them and causing issues. They sit right under your intercooler, and during a rainy day you'd definitely take in some water through the air inlet for the i/c.
