I have a 2006 RL that I bought 6 1/12 years ago with 105K miles. Now has 150K. I am curious what you experts think I may have to replace/repair during the next 50K miles (150K to 200K miles). Here is the list of repairs so far (not including oil & filter change, fluids, filters, wear items like brake pads, tires, wiper inserts - which are done at or before recommended intervals).
1. 2/08 24K Power steering hose leak (TSB repair)
2. 9/10 50K Battery
3. 12/10 52K Master cylinder (TSB repair)
4. 6/11 68K Stroke Sensor
5. 5/13 105K Timing belt, pulleys, tensioners, drive belt, coolant, water pump, spark plugs
6. 10/14 119K 4 wheel alignment
7. 7/17 135K arm rest latch
8. 8/17 136K Left tail light

Needless to say this car has been quite problem free. I will need to replace tires next summer and do the timing belt service (which I do myself) in 2020 also. The strut may be getting a little weak but do not leak or bounce abnormally. The car uses NO oil and the transmission shifts like new. Air conditioning works well. What about the expected life of alternator, starter, radiator, air conditioning compressor, wheel bearings, etc.? Thanks for your help.

 

The main things outside the normal wear items would be the TB/WP and all the belts in the engine bay. Other than that, if it's not broke don't touch it. Most major items should last the life of the car. Fresh fluids would be a great idea if you haven't done so in a while i.e brake fluid, coolant, PS fluid, and transmission/differential. Fuel filter might be a good idea if hasn't been done as well.

In regards to the suspension parts, if you have signs or symptoms of something wearing down, address it, otherwise I wouldn't bother. But if you have extra funds laying around, I would personally overhaul the suspension. I made an excel of all the parts I want to replace to make the car feel nice and tight again.

 

I have an '06, similar miles to yours. Most recent stuff has been an A/C compressor ($1,400 to do it right, unless you can turn a wrench, which would save you nearly half) and an alternator, which failed with only about 30 minutes' warning. Apparently both of these are fairly common items. If your headlight bulbs/ballasts have never given you trouble, either they've been replaced once already or they're candidates too. But all the other basic stuff on this car can go forever.
