Engine 6.0l, check engine light on, code p0299, 'underboost", car owned since new, odometer now has 12,100 mlesi ford dealership reporting that engine turbo-compressor may need replacement
As I'm driving, the horn will sometimes just start blowing by itself for no reason. This is an extremely unsafe as when I'm driving and this happens, it's will scare me completely and usually those around me. I have to quickly pull over and bang on the horn to get it to quit blowing. It seems to be in the airbag area. Thank you.
Had 8 broken exhaust bolts on this 6.8 v10 only 54687 miles on the truck.
The truck stalled when I was going 70 mpg on the interstate in traffic and would not restart until it sat for 3 minutes.
Engine,6.0 diesel was loosing water. Took the vehicle to the dealer and was told that the head gaskets were blown and that the head bolts were soft and had stretched. This is a known fault with this engine according to the dealer. If it is a known fault, why hasn't there been a recall to fix this. I have never known an engine to have blown head gaskets at 104,551 miles. There are numerous service bulletins on this problem.
Brake line failed catastrophically due to corrosion resulting in loss of all brakes after only 9.5 years and 67000 miles.
Lack of power or runs rough condition, and/or the malfunction indicator light on with egr related diagnostic trouble codes (p0401, p0402, p0403, p0404, p0405, or p0406). Engine and engine cooling:exhaust system:emission control:gas recirculation valve (egr valve).
Right front wheel bearing and anti-lock system failed, crossed the center line in the town .stepping on the brakes only made matters worse; because now it pulled harder to the left. Crain ford after replace every part on the right side. Shortly after that it again the truck pulled to left and the brakes had to be replace because of a bent caliper. There was steering joint replaced,u joint, and wheel bearing then after brake pads and a caliper on the right side.
Driving truck down road I hear the radio shut off, then all dash board lights are off. Look at the dash board gauges and they are going nuts fuel , battery , temp gauges, and speed o would pin below 0 the tach gauges would pin as high as it would go then start moving up and down fast. . Last a few mins then go back o normal. I pulled the truck in the driveway it started all over again and this time it was dark out and all the out side light were off with everything above and the windows would not go down or now if they are down the wouldnt go up.
