Do your homework
Models to Research Carefully
Not deal-breakers — but they reward a careful buyer.
MDX / TLX (2016–2018, 9-speed ZF)
The early 9AT calibration was rough. Software updates and later production years improved shift quality dramatically. Verify calibration and fluid history.
RLX (2014–2020)
Fine flagship but limited sales mean parts and dealer familiarity are more variable. SH-AWD is complex when it needs service.

Ownership
Maintenance Costs
Acura service is a small premium over Honda service — and most Honda-familiar independent shops handle Acuras identically. Parts are cheap and plentiful.
The V6 engines rarely need major work. Timing belt service on older J35s (every 105k) is the main scheduled expense.
