Platform Heritage

The Acura MDX is a mid-size luxury crossover SUV with three-row seating produced by the Japanese automaker Honda under its luxury Acura division since 2000. The alphanumeric moniker stands for "Multi-Dimensional" luxury. It has ranked as the second-best selling mid-size luxury SUV after the Lexus RX in the U.S. The MDX was introduced on October 5, 2000 as a 2001 model, replacing the slow-selling U.S.-only body-on-frame SLX, based on the Isuzu Trooper. In Japan, it was made to replace the Honda Horizon (also based on the Trooper) which was discontinued in 1999. In 2003, the vehicle went on sale in Japan and Australia as the Honda MDX; sales with Honda badges ended with the introduction of the second generation three years later.

Vehicle health varies wildly by individual history. Aggregate recall and complaint data cannot tell you whether the specific car on the lot had its monitors cleared or its odometer rolled back. Verify the physical or digital scan before you sign a bill of sale.
