The Belt-or-Chain Question Nobody Explains Well
This one catches a lot of Acura owners off guard, and it's worth understanding on its own before anything else. It depends entirely on the engine.
Four-cylinder Acuras, like the ILX, run a timing chain. A chain is built to last the life of the engine and isn't a scheduled maintenance item, it only needs attention if something actually goes wrong with it.
V6 Acuras, including the MDX, TL, TSX, and RLX, run a timing belt instead. A belt is a wear item with a hard interval, typically around 105,000 miles or seven years, whichever comes first. These are interference engines, which means if the belt lets go, the pistons and valves collide. That's not a repair, it's an engine.
The honest version of that math: a timing belt service runs a few hundred dollars. Ignoring it and losing the bet costs thousands. We track your specific engine and interval so you're never guessing which one applies to you.
VCM Oil Consumption
Acura issued a technical service bulletin covering certain 2010-2013 MDX, 2011-2012 RL, 2009-2014 TL with SH-AWD, and 2010-2013 ZDX models for oil consumption tied to the Variable Cylinder Management system. Carbon deposits can clog the oil control rings enough that the engine burns more oil than it should. If your Acura needs oil added between changes, the right first step is an oil consumption test, not just topping it off indefinitely.
The 9-Speed Transmission
Acura moved the MDX from Honda's long-proven 6-speed automatic to a ZF-sourced 9-speed starting with the 2015 model year, and early versions had a documented tendency to shudder or shift roughly, especially from a stop. A software update resolves it in some cases; the fluid condition and torque converter are worth checking in others.
NSX: A Different Animal Entirely
The second-generation NSX isn't really comparable to the rest of the lineup. It pairs a twin-turbo V6 with three electric motors in a hybrid all-wheel-drive supercar layout, and it deserves the same specialized respect any hybrid performance car does. If you own one, the routine and diagnostic side is something we can speak to honestly, and we'll tell you plainly if a repair falls outside what makes sense for us to take on.
