2006 with 68K miles.
So far,
replace all brakes - $700

intake gasket leak - $1200
front wheel bearing units replaced because kept activating traction control - $1000
replace all gas lines and brake lines due to rust - $750
replace brake line distributing valve - $1200
replace rear bumper due to rust - $300
still broken and not fixed yet,
driver butt heater shorted out, causes driver seat heater control on door to turn itself on and off randomly
front speakers(doors and pillars) randomly work and don't work
front bowtie looks like it is half full of water, needs replaced
clear coat coming off front left fender
Update...replace muffler and header pipe $500
Ok, update again. Have metal welded in to repair both sides rocker panels rusting from the inside out and repaint front left fender. First they get a few "dots" on them, then the dots turn into finger sized holes. $3200
Replace both headlights due to fogging. $125
Replace tailgate latch mechanism because tailgate would no longer latch on either side and have temp control recalibrated because air conditioning stopped working. $300
New bowtie. $50
I guess I should have also included the new "take off" wheels that had to be put on it because the stock ones started corroding. That was about the first thing that got replaced on the truck. That was about $400 off ebay. Still have not replaced the shorted butt heater though.
Oh, up to almost 76,000 miles now.
