The 2001 Acura MDX has 4 recalls, the most serious being a driver's airbag inflator that can rupture in a crash and send metal fragments into the cabin, striking the driver or passengers.
This airbag defect appears in two separate recalls: one covering vehicles with their original factory airbag module, and one covering vehicles where the driver's airbag was previously replaced as part of a repair. In both cases, the inflator can fail the same way during deployment, so owners whose vehicles have had airbag work done in the past are not necessarily protected.
The remaining two recalls both involve the front suspension coil springs and describe the same underlying issue: these springs can corrode heavily, particularly in states where road salt is common, and a spring that breaks under corrosion can puncture a front tire. A sudden front tire failure while driving raises the risk of losing control of the vehicle. Rubber sleeves applied to some springs to reduce noise can trap salt water against the metal, accelerating the corrosion and increasing the chance of spring failure.
