2005 Ford F-150 2dr Regular Cab XL Rwd Styleside 6.5 ft. SB (4.2L 6cyl 5M)
i'll start by telling that i am a ford motor company retiree with over 30+ years on the assembly line. my 2005 f-150 has lived up to the problems common to the 5.4L engine. sparkplug issues, timing and cam phasor issues, and a bad cylinder head to name a few. all difficult and expensive to repair. i have confirmed many of these problems with ford dealer mechanics, and private repair shop mechanics. as a group they all confirm that engine issues are becoming a big problem for 2005-2008 ford trucks, vans, and large suv's. the real problem lies with the manufacturer. ford is not backing up their claims of top quality and reliability. what a shame that they deny their responsibility!!!!
i'll also add that i'm sure most ford products are highly reliable and good quality. i like my trucks comfort, good ride, handling, towing capacity, and space.
ford definitely needs to address the mechanical issues common to the 5.4L engine and drivetrain. better gas mileage would also help a lot.
