I've had my white 90D X for almost 3 months and ever since the first day I noticed small, greasy black spots on the sides starting at the wheel well and tapering towards the back of the car. It looks like splatter from the front wheels (see pic). The curious thing is that no matter where I drive or how far I drive the spots always appear. I chalked it up to normal road dirt but today I got it back from the detail shop and drove it straight home. The first thing I see when I close the door is the splatter. Always the same type of substance, always almost the identical pattern. It happens on both sides but it is heavier on the right side. A few weeks ago I noticed a big blob of grease right on the spot where the splatter occurs. Has anybody experienced this? I'm starting to think there's something 'dripping' on the wheels and thus shot out to the sides. I don't know if it is normal or something I need to have checked.
