Kestrel Take
A comfortable, well-built near-luxury sedan with Honda mechanical DNA — the 3.5L V6 is smooth and durable. The one caveat is the 9-speed automatic (V6 cars), which drew complaints for clunky, hesitant shifts early on; software updates improved it. A well-sorted TLX is a reliable, refined value; confirm the transmission software and test-drive the shifts.
What we checked
Reconciled against public records, 2026-09-25
NHTSA holds 341 owner complaints for the 2015 Acura TLX V6, and 6 recall campaigns.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 47% of them are about one thing — the transmission and drivetrain. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.
6 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
