Came across this thread and figured I would tell what maintenance I have had done. It is a 2010 with the 5.4 L and 130,000 miles. So far I have replaced...
Passenger temperature door actuator at 50,000 miles for $170
Blower motor resistor and HVAC door at 95,000 miles for $600
Radiator/hoses/serpentine belt at 105,000 miles for $1,200
Spark plugs at 115,000 miles for $500
Fuse relocation kit at 116,000 for $600
Replaced the alternator at 128,000 for $500
Other than those issues it has been very reliable. I am needing some new or rebuilt shocks badly as they are still the original ones, but I am on a tight budget currently so trying to find some used ones for cheap. Does anyone have some suggestions for preventative maintenance that I should get done?
