I was detailing my car last week and noticed that the shifter knob now, for some strange reason, has developed horizonal cracks. They seem to have spread from the front to the back, 2 on each side. Anyone else had this problem? It is the woodgrain pattern. The knob has not been abused, or hit with anything, so I dont know why they have appeared. Our winters are not that cold, nor has it been hot yet, for a drastic change in cold/hot in the car. The car is a 2004 and these cracks have just appeared in the past month. Any thoughts? :dunno:
