This is the from the ownership estimate of a TL 2012. Found nothing on the TLX. Doesn't look right to me.

Used 2012 Acura TL: True Cost to Own | Edmunds

 

If you take a look at the definitions:
"This is the estimated expense of the two types of maintenance: scheduled and unscheduled. Scheduled maintenance is the performance of factory-recommended items at periodic mileage and/or calendar intervals. Unscheduled maintenance includes wheel alignment and the replacement of items such as the battery, brakes, headlamps, hoses, exhaust system parts, taillight/turn signal bulbs, tires and wiper blades/inserts. Estimated tire replacement costs are supplied to Edmunds.com by The Tire Rack, Inc."

Seems nuts to me. I checked a couple Lexus models I've had--same $2k+ figures, all I had to do was pay for oil and filter changes. Year one on my TLX--same.
