The A/C unit had a problem about four years back. It just stopped putting out cold air. The dealer replaced the compressor and within two days, the freon was gone. I was not able to have it fixed again right away and it probably helped cause some more problems. Bottom line, the dealer worked with Mazda and replaced a couple of hoses (expensive) and the evaporator for an additional $100. Effectively got a new system for not too much money.
The Bose radio and CD player stopped performing well and it could be for lack of use. Replaced unit with Panasonic and kept Bose speaker system. Works great.
The auto antenna had broken the plastic lead and will have to be replaced. Wish there was some way to retrieve the part of the plastic tail that is still in the antenna tube. Mazda sells the mast separately.
The rear lifts do not help raise the trunk anymore. They will hold it up fine, but you have to lift. Purchased the new hydraulic lifts, but have not yet installed.
Change oil religiously based on time, not miles as I don't drive it everyday. Use Mobile One synthetic and it seems to work great.
Mileage is about 18 mpg overall now that we live in NC (less traffic) but it was around 15 mpg when we lived in Baton Rouge.
Car has always been garaged and only driven in rain about five times. Paint and interior have held up extremely well. No signs of aging.
Car is comfortable on interstates as long as they are smooth. Suspension is hard which contributes to the great handling.
I'm glad you like your RX. I work for Mazda and it's one of the best looking best handling cars we ever made. On the synthetic oil though, I would be cautious. We don't recommend synthetics because the engine uses a small amount of oil in the combustion process. Here is a link to a FAQ about it from Mazdatrix. http://www.mazdatrix.com/faq/synthetc.htm.
Drive it like you stole it!
