The failure pattern owners describe
The 2008 Azera electrical complaints cluster around safety-critical failures. Power driver's seat malfunctions top the list: seats move forward on their own while driving or even when the car is parked and off, pinning occupants against the steering wheel. Owners report the issue recurs after manual reset attempts and persists despite dealership efforts to clear "seat preference" memory settings.
Airbag system faults are equally serious. The airbag warning light illuminates due to defective passenger seat belt tension sensors, and at least one owner had the sensor replaced under warranty only to see the same warning reappear later. Hyundai has refused to cover sensor replacement costs even though the sensor sits on a previously recalled wiring harness.
Throttle sensor failures cause sudden, complete loss of acceleration at highway speed—three instances reported in one vehicle, forcing the driver to coast to safety. An anti-lock brake control unit failed at 132,000 miles, ejecting white smoke and leaving the vehicle immobilized.
The most severe failure involves engine compartment fires. Two owners report fires occurring while vehicles were parked and off, with keys out of the ignition. One fire destroyed a home and both vehicles. Hyundai's official recall 18V026000 attributes fire risk to water entering the ABS module and causing electrical shorts.
Additional electrical gremlins include stuck ignition switches, doors that unlock randomly during operation, and—in one case—oil leaking from the cylinder head gasket directly into the alternator, identical to a previously recalled design flaw in the Veracruz.

Failure modes owners describe
Power Driver Seat Unintended Forward Movement
Driver's seat with power controls moves forward autonomously while driving or when vehicle is parked and off, pinning the driver against the steering wheel. Issue persists even after clearing seat preference memory and occurs repeatedly during single trips.
When: Occurs while driving on highway and while parked with vehicle off; one owner reported 80k miles on vehicle
Symptoms owners cite: Seat moves forward on its own while driving; Seat pinches driver against steering wheel; Seat repositions forward even after being manually moved back; Seat moves forward when vehicle is parked and turned off; Seat belt tightens uncomfortably during movement; Manual override with seat switch becomes difficult or unresponsive; Seat moves with no one in vehicle
Repairs/costs cited: Dealership attempted to address by clearing 'seat preference' memory; one owner reported vehicle towed to Hyundai dealership for repair but no outcome stated
Airbag System Malfunction—Passenger Seat Belt Sensor
Airbag warning light illuminates on instrument cluster, often accompanied by passenger seat belt warning. Diagnostics reveal defective front passenger seat belt tension electrical sensor or wiring harness issue. Problem recurs after dealer replacement in at least one case.
When: Intermittent initially, then persistent; symptoms noted 2+ years into ownership in one case
Symptoms owners cite: Airbag warning light on dash; Passenger seat belt warning light; Airbag light stays on continuously even when passenger seated or not; Warning lights intermittent then become persistent
Repairs/costs cited: Dealer replaced front passenger seat belt tension electrical sensor (cost ~$500 in one case); wiring harness was object of prior recall; replacement did not resolve issue long-term in at least one case
Recalls/TSBs owners mention: Hyundai declined to cover replacement cost under warranty despite sensor being on previously recalled wiring harness
Engine Oil Leak into Alternator
Oil leaks from front cylinder bank gasket directly into alternator, causing premature alternator failure. Owner notes this is the same failure mode as recalled 2006–2012 Hyundai Veracruz (NHTSA Campaign 14V415000) due to shared engine design.
When: Reported at 80,000 original miles
Symptoms owners cite: Oil leaking from front cylinder bank into alternator; Alternator failure
Recalls/TSBs owners mention: No Hyundai response mentioned in narrative; owner references existing Veracruz recall 14V415000
Engine Compartment Fire
Engine compartment catches fire while vehicle is parked, off, and key is not in ignition. Per NHTSA Recall 18V026000 (issued 1/24/2018), water can enter anti-lock brake module causing electrical short that increases fire risk whether vehicle is on or off.
When: One fire reported 1/10/18 (2 weeks before recall announcement); vehicle sat unused ~48 hours; fire occurred at 3:30 AM
Symptoms owners cite: Fire in engine compartment; Vehicle parked, off, key not in ignition; Fire occurred after vehicle sat unused for approximately 48 hours
Recalls/TSBs owners mention: NHTSA Recall 18V026000 issued 1/24/2018 for 2006–2011 Azera and 2006 Sonata; recall attributed to water intrusion into anti-lock brake module causing electrical short; Hyundai stated repairs would be made free of charge; manufacturer has not accepted responsibility in at least one case where fire occurred prior to recall notice
Hydraulic Electric Control Unit Failure—ABS System
Anti-lock brake hydraulic electric control unit fails suddenly during driving, accompanied by warning light illumination and visible smoke from front of vehicle.
When: At approximately 132,000 miles
Symptoms owners cite: ABS warning indicator illuminated while driving ~60 mph; White smoke from front driver's side; Hydraulic electric control unit failure
Repairs/costs cited: Dealer diagnosed need for hydraulic electric control unit replacement; vehicle was not repaired at time of complaint
Throttle Sensor Failure—Loss of Acceleration
Throttle sensor malfunction causes abrupt loss of engine acceleration while driving, with check engine light illumination. Occurs multiple times during single trip, forcing driver to coast to safe location.
When: Occurs while driving at highway speeds (60–75 mph)
Symptoms owners cite: Check engine light illuminates; No acceleration ability despite depressing throttle; Loss of motive power
Repairs/costs cited: Dealer identified throttle sensor as defective in both reported cases
Ignition Switch Failure
Ignition key becomes stuck and will not turn in either direction in the ignition cylinder. Owner notes this is a common problem for Hyundai and Kia vehicles.
When: After parking vehicle
Symptoms owners cite: Ignition key will not turn in either direction; Vehicle cannot be started or moved
Repairs/costs cited: Dealer determined ignition switch and housing required replacement; vehicle required towing
Driver Door Unintended Unlock
Driver's side door randomly unlocks without user action, occurring most often at idle, during acceleration from stop, or at low speeds. Auto-lock function becomes disabled for several seconds after each occurrence, preventing re-locking.
When: Began rarely, now occurring daily; timeframe not specified
Symptoms owners cite: Driver door randomly unlocks; Occurs most when idling at complete stop; Occurs during acceleration from complete stop or slow speed; Auto-lock function disabled for up to several seconds after each unlock; Door cannot be relocked during disabled period; Frequency increasing over time
