    04/2010 Freeway road was uneven at end of bridge. I hit dip going 60 mph. Truck bottomed out and I nearly lost control. Check engine light came on. I spent $100 to have problem diagnosed as broken fuel cap.

    03/14/12 Happened again. 13 reported problems? I think the dealer should refund me the $200 I spent to diagnose this problem.
