Summary
The Hyundai Azera has 7 recalls spanning the 2006–2013 production run, with the most serious affecting 2006 models where road salt corrodes the rear crossmember until the control arm separates at its mounting point, allowing the rear wheel to swing off-axis and causing loss of vehicle control.
The next most relevant issue for late-production owners involves 2012–2013 vehicles, where the passenger seat sensor can misread the front passenger as an adult, child, or empty seat when it is not. In a crash, this causes the airbag to fire with more or less force than the situation calls for, raising the risk of injury to whoever is sitting there.
Going back to mid-production years, Recalls 4, 5, and 6 all share the same underlying defect: on 2006–2009 models, the wiring harness for the right front seatbelt tension sensor can wear through with repeated seatbelt use, disabling the sensor. When that sensor fails, the front passenger airbag may not deploy in a crash.
The 2007 model year has a separate seat-related issue where a short in the driver's power seat switch can send the seat moving forward, backward, up, or down without any input from the driver. This same unintended seat movement, attributed to a broader electrical fault, also affects certain 2007–2008 vehicles and carries the same consequence: a driver who suddenly finds their seating position changed while in motion has reduced ability to control the vehicle.
