So I went through the car wash today. I have taken my FJ through this car wash no less than a 100 times. I have made no changes to my vehicle and have been leak free for 3 years. I do have wiring going through the rack that has been there for 2 years. Well upon exiting I notice a darker color on my headliner right above the a pillar right above the grab handle. I have removed the a pillar and the handles to get up into the headliner to look for signs of the leak. The inside of the headliner is perfectly dry. It does not look like it is coming from the winshield and I would think it would bet wet closer to the windshield in that case too. I am leaning toward the roof rack. Would it be likely that my rack would start to leak after such a long time?
