The 2018 Acura TLX received a styling refresh and uses the K24W 2.4L 4-cylinder with an 8-speed DCT, or the J35Y6 3.5L V6 with the ZF 9HP 9-speed automatic. The ZF 9-speed in the V6 is the well-documented weak spot; the 2.4L+DCT combo is much more reliable. Watch for 9-speed harsh shifts, infotainment dual-screen lag, and minor electrical items.
The 2.4L 4-cyl with 8-speed DCT is one of the more reliable luxury sedans sold. The 3.5L V6 with the ZF 9-speed inherits the same hesitation and harsh shifts as the Jeep Cherokee and Range Rover Evoque.
9HP 9-speed has hesitation, hard 1-2 shifts, and occasional limp mode. Multiple Acura software updates over the years. Severe cases needed valve body replacement.
