2006 Cadillac DTS Luxury III 4dr Sedan (4.6L 8cyl 4A)
Bought mine gently used with 23,000 miles. Just off lease. Has everything but distronic style cruise. My wife loves the cooled seats and massage. Just had heated windshield fluid option disabled due to recall. Worked well. Got $100 back from GM. I replaced the third brake light on trunk lid. LED's were going out and I discovered issue as I replaced it. The first screw, of seven, was over torqued during manufacture and let water into the led housing. You must replace entire unit. About $125.00. I see lots of DTS's with same issue. New one works well. Only other repair was front wheel hub/bearing. Rough winter/potholes in Ohio. A great car, fantastic ride and the last of the big ones.
Ride, simple controls. Lots of toys. Tons of room. Looks great and runs great.
Replacing the small light in headlight assembly (not the amber or LED) requires removal of front bumper fascia and splash guard(s) and wheel well liner to access. Just a bit of Old GM engineering showing. Small light, big bill at dealer or 4 hour knuckle scraping job at home.
