First problem started with the brain in the transmission area. Hesitating, lunging forward and tachometer jumping when taking off and during driving down the roads/highways. Had diagnostics tests done (March 3, 2016. ) replaced brain and it stopped the hesitation, lunging and tachometer jumping=$2700. 00. Next problem came along when we started hearing a ticking sound when it was started in the driveway(may 16, 2016. ) come to find out the engine was blown which is now going to cost $6700. 00. We have always maintained our vehicles with proper care and attention, but how can all these major things go wrong at only 108000 miles???.
The truck make a horrible ticking noise when you start it up. It will do this until the oil gets thru the motor. Ford states that it is the nature of the motor for normal wear and tear. It is embarrassing to say the least, as it sounds like a ticking time bomb that is waiting to go off. After the truck has been running for a few minutes than the noise goes away, seems that if I spent this much money on a vehicle, it wouldn't sound like an old cluncker.
