Ford Motor Company-there was a service bulletin put out show there was a problem with the cam phasers and cam chain tensioner causing the engine to make noises and then engine failure there has been lots of complaintsto Ford with nothing being done if you where driving onthe road and the engine blew couldcause a accident I contact Ford and they have all most admitted to it that they new there was a problem I have found that there has been 1092 complaints over this problem and nothing done. I contacted Ford and that's how I found out about you they keep saying there sending the complaint to another dept..but this is aproblem that could have been correct before the engine was ruined.

The contact owns a 2005 Ford F-150. The contact stated that she heard a grinding noise while driving at any speed. The noise was heard intermittenly. The dealer could not duplicate the failure. The vehicle later locked into 4-wheel drive while driving less than 55 mph. The vehicle was taken to the dealer and they found that the solenoid and the switch for the 4-wheel drive were defective. The contact paid $185 to have the vehicle repaired. The dealer was unsure if the repair would correct the failure because the electrical switch was susceptible to water damage. The current and failure mileages were less than 37,217. Updated 08/11/09.

While driving, the vacuum solenoid for the 4 wheel drive tries to engage the 4 wheel drive - even at highway speeds- resulting in a horrible sound. The sound was "like I had run over a shopping cart or hit something in the road and was dragging it under the truck". this happened 5 times in two days in less than 30 miles of total driving. The noise is so loud and alarming that it made me immediately apply the brakes and pull to the side of the road because I thought I had hit something/someone. At first I wondered if my muffler or drive shaft or some other part had fallen off of the truck. This "false engagement" of the 4 wheel drive happens without any warning in all kids of driving conditions (slow, fast, breaking or accelerating). A new, redesigned (now has a cover on it to keep moisture out- which was causing the failure) vacuum solenoid was installed on truck - a $27 part. Dealership kept old part. Tech. At dealer told me that this part will go bad at some point and need replacing on all the trucks with the part. He said "not if but when". Ford knew about the problem - hence the redesigned part. Ford has not notified owners of this part and it's impending failure.

Truck will not disengage from 4hi and even though it is turned off it will make a terrible grinding sound, which I think has something to do with the transfer case. The light doesn't come on when for 4hi, so I am also thinking there is something wrong with the relay switch.. also our truck vibrates, but has only done it twice, however the truck only has 68 thousands kilometers on it, it is like a brand new truck. We have had it to the Ford dealer and they say nothing is wrong with it. Are they actually waiting for someone to die in one of these trucks. How many complaints does it take?
