The 2007 Acura RDX has 3 recalls, the most serious being a Takata airbag inflator defect where the driver's frontal airbag can explode and send metal fragments into the cabin, potentially causing serious injury or death.
The airbag issue stems from a known inflator problem that affects a wide range of Honda and Acura vehicles from this era. When the airbag deploys in a crash, the inflator can rupture rather than inflate normally, turning the airbag housing into a source of sharp metal shrapnel directed toward the driver and other occupants. There is also a structural concern for vehicles equipped with a dealer-installed accessory trailer hitch: the hitch welds may not have been applied correctly, meaning the hitch can fail under load and allow a trailer or towed unit to detach from the vehicle while in motion.
