Only repairs I've done on my 07 V6 2WD is update the engine/trans software, replace the fan motor controller (see in Projects) and replacement of the rear axle boots. However, I bought it used nearly three years ago at 32K (now at 65K), and previous owner had done nothing other than oil changes, so I started getting this car "caught up" on maintenance items like Bob C mentions. Changed all driveline fluids to AMSOIL synthetics, coolant, fuel/air filters, alignment, serp belt, spark plugs, brake fluid. Changed brake pads at 61K though could have gone longer. I had an aviation ops career, so I spend a little extra money along the way prospectively so that my cars run well and don't break down. Keeping maint records organized has also helped me sell a car quickly, by the way. Free AMSOIL "MyGarage" will help you.
