Two problems related to instrument panel have been reported for the 2006 Ford F-250. The most recently reported issues are listed below.
Speedometer would no longer go below 26 mph, even with vehicle stopped and ignition turned off. Driving vehicle would indicate a speed constantly 26 mph faster than actual speed. Brought to dealer where dealer ordered and later replaced entire instrument panel. Second problem involved passenger side wiper arm fell off while in operation driving during rain. Dealer replaced wiper arm.
Purchased vehicle 5 weeks ago. Have 5k miles on it. Speedometer started sticking at 30 mph and continued to vary. Parked with power off it still reads 20 mph. I am at work out of town (5 1/2 hours from home) have not taken to dealership yet.
