, too! The most common 2012 Acura MDX problems
Let’s start with the good news first. The 2012 Acura MDX was welcomed to the 2012 model lineup with great reviews. It was ranked in 4th place on the J.D. Power 2012 list for best midsize premium SUVs.
At the time of its release—before some of the mechanical problems complicated matters—it was thought to have a pretty good gas mileage for its size and class. And the Acura MDX with a V6 engine
produced a robust 300 horsepower. But the 2012 MDX’s problems can’t be overlooked. There were 61 complaints made to the National Highway Traffic Safety Administration (NHTSA).
The complaints were distributed fairly evenly across four main topics—the engine, powertrain, electrical system, and airbags. The MDX was recalled due to a problem with a component of the fuel tank assembly—the vent shut float valve case—which caused fuel leaks and potentially created a risk of fire.
The 2012 MDX also had transmission problems. Sometimes the issue turned out to be a faulty sensor, but in cases in which the driver noticed rough shifting, the likely cause was transmission failure—an expensive repair that drivers dread hearing of.
