Redesigned Fog Lamps for 05 GXP.
My car was at the dealer today for a service. While I was there I mentioned that the fog lamps have been going out at a rather frequent rate. The service manager called me in work later to let me know they ordered parts for my car? "For what, it was a service".
The mechanic had noticed the steering was clunking (my wife noticed this but I never did) so they are replacing the intermediate shaft, and also they are replacing the fog lamp modules. Seems they have a different housing for the lamps that will keep moisture out and will replace them if noted as faulty.
So, if you are having a problem with them, there is a permanent fix. You just need to contact the dealer.
