The failure pattern owners describe
Owners report widespread electrical faults hitting multiple vehicle systems. The most persistent complaint involves driver's power seats moving forward, tilting, or reclining on their own—sometimes while driving, sometimes parked, occasionally with the engine off—occasionally pinning drivers against the steering wheel. One owner replaced the power seat wire at 24,000 miles; dealers found shorts in seat switches; in other cases the failure could not be reproduced.
Airbag and occupant detection lights malfunction frequently: airbag warnings stay on or flash on after minor impacts like potholes, and passenger seatbelt lights come on with an empty seat. One owner reports the passenger airbag light stays on continuously, raising the concern that the airbag may not deploy in a crash. Occupancy modules have been replaced at 75,000 miles with no lasting fix reported.
A stubborn no-start condition plagues some vehicles, where the engine cranks but won't turn over—jump-starting doesn't help, and replacing the battery and starter twice, plus the starter wire, only provided temporary relief before the fault returned. All four windows rolling down uncontrolled at highway speed, horn failure, ABS module leaks, and power sunroof/heated seat failures round out the roster. One owner reports engine oil seeping from a corroded head gasket onto the alternator, causing electrical shorts—a defect other manufacturers recalled but Hyundai did not address on the Azera.

Failure modes owners describe
Power seat malfunction (driver's side)
Driver's seat moves forward, tilts forward, reclines, or shifts backward without operator input, sometimes while driving or when vehicle is parked or even powered off. Movement can pin driver toward steering wheel, creating steering and brake interference and airbag deployment safety concerns.
When: Between 24,000 and 160,000 miles; some cases within first few thousand miles
Symptoms owners cite: Seat moves forward unexpectedly while driving; Seat tilts forward on its own; Seat moves when parked and vehicle powered off; Seat reclines without input; Driver pinned against steering wheel
Repairs/costs cited: One owner reports BTS (power seat) wire in passenger seat replaced at 24,144 miles; dealers found short in seat switch; one dealer unable to reproduce failure; repairs appear to vary or unresolved in multiple complaints
Recalls/TSBs owners mention: No recalls or TSBs mentioned for driver's seat electrical control issue; dealership diagnostics performed in some cases
Airbag warning light malfunction
Airbag light illuminates and remains on, sometimes intermittently, or light appears after minor suspension events like hitting potholes. Light does not clear and persists despite recall work performed.
When: Throughout vehicle ownership; one case at 52,000 miles
Symptoms owners cite: Airbag light comes on and stays on; Airbag light comes on after hitting pothole; Airbag light intermittently on for days or weeks then off again; Airbag light persists after recall 172 completion
Repairs/costs cited: One owner reports airbag light persists after dealer diagnostic; some dealers apparently closed recall 172 despite unresolved light
Recalls/TSBs owners mention: Recall 172 issued and performed (stop lamp switch replacement and underbody corrosive protection noted); owners report issue remains unresolved
Passenger seatbelt and airbag sensor false activation
Passenger seatbelt indicator light and passenger airbag light illuminate when passenger seat is empty or unoccupied, suggesting occupancy sensor or wiring fault. In at least one case, passenger airbag light stays on continuously, raising concern that airbag will not deploy in actual accident.
When: Throughout vehicle service life; one module replacement documented at 75,000 miles
Symptoms owners cite: Passenger seatbelt light comes on with no occupant in seat; Passenger seatbelt light comes on intermittently despite seatbelt worn; Passenger airbag light stays on when seat empty; Continuous passenger airbag light activation
Repairs/costs cited: One owner reports occupant detection module replaced at 75,000 miles; repair did not resolve recurring false activation in that case
No-start condition with cranking power present
Vehicle fails to start intermittently at random, though electrical accessories (lights, radio, door chime) operate normally and jump-starting does not resolve the issue. Problem persists even after battery and starter replacement and starter wire replacement. Requires multiple attempts to start (8th to 25th try).
When: Started around 79,000 miles; occurred repeatedly over 10,000-mile intervals
Symptoms owners cite: Engine cranks but will not turn over; Accessories operate but vehicle does not start; Jump-starting does not help; Requires multiple ignition attempts; Intermittent failure recurring after repair
Repairs/costs cited: Owner replaced battery and two starters; wire to starter replaced; repairs temporary (lasted ~10,000 miles), then problem recurred; suggests possible deeper electrical issue in ignition or fuel/spark circuit
Power window uncontrolled operation
All four windows roll down simultaneously while vehicle is in motion at highway speed without operator input. Power window controls do not respond to close command, rendering windows inoperable.
When: At 160,000 miles
Symptoms owners cite: All four windows roll down on their own; Power window controls unresponsive; Windows cannot be closed via control switches
Repairs/costs cited: Owner had to unlatch doors and tape windows closed; vehicle was not diagnosed or repaired
Recalls/TSBs owners mention: Dealer and manufacturer not notified
Horn inoperative
Horn fails to produce audible sound when activated. Both horns required replacement despite no prior horn operation.
When: Timing unclear; noted when owner attempted to use horn
Symptoms owners cite: Horn does not produce sound; No audible output when horn button pressed
Repairs/costs cited: Both horns replaced
ABS module failure with brake fluid leak
ABS module fails due to internal brake fluid leak within the module itself, affecting braking system function and electrical safety. Failure occurred shortly after manufacturer recall 172 was performed.
When: Two weeks after recall 172 performed at 07/03/2020
Symptoms owners cite: ABS module inoperates; Brake fluid leaks inside ABS module; Braking performance affected
Repairs/costs cited: ABS module replacement cost $500 out-of-pocket for owner; dealership initially quoted $4,000, then reduced to $300
Recalls/TSBs owners mention: Recall 172 performed two weeks before failure; manufacturer denied reimbursement claim
Passenger side dashboard cracking (airbag area)
Visible cracks develop on dashboard around passenger-side airbag area, raising structural and deployment safety concerns.
When: Timing not specified
Symptoms owners cite: Visible cracks around passenger airbag on dashboard
Check engine light and engine management issues
Check engine light and ESC (Electronic Stability Control) OFF light illuminate on dashboard. In one case, vehicle fails to accelerate properly upon cold start despite full throttle input, suggesting fuel or ignition system electrical control failure.
When: Timing and mileage not specified
Symptoms owners cite: Check engine light illuminates; ESC OFF light on dashboard; No acceleration response in morning starts despite floored pedal; Vehicle unresponsive to throttle input
Alternator failure from oil seepage (head gasket corrosion)
Head gasket corrosion allows engine oil to seep onto alternator, causing alternator short and engine warning lights. Owner notes other vehicle makes with same engine received recall for this issue; 2007 Azera did not.
When: Timing not specified
Symptoms owners cite: Alternator shorts out; Engine warning lights flash; Oil seepage from head gasket onto alternator
Repairs/costs cited: Repair cost owner $1,500+
Recalls/TSBs owners mention: Other manufacturers issued recalls for same defect; Hyundai did not recall 2007 Azera for this issue
Battery drain
Battery becomes drained, rendering vehicle unsafe to drive.
When: Timing and mileage not specified
Symptoms owners cite: Battery drained; Vehicle unable to start or operate
Cigarette lighter non-functional
Cigarette lighter ceases to operate.
When: Timing not specified
Symptoms owners cite: Cigarette lighter does not work
Sunroof and rear window electrical failure
Sunroof window and back driver-side window stop operating; heated front seats also non-functional, along with persistent airbag lights.
When: Timing not specified
Symptoms owners cite: Sunroof inoperative; Rear driver window inoperative; Heated seats non-functional; Airbag lights stay on

What owners are reporting 4 most recent
About two weeks ago, the back portion of the front driver's side seat began moving forward automatically while I was driving the car. I also noticed that when the car is parked the seat would move forward as well. When the seat moves forward, I am put very close to the steering wheel, which makes it difficult to steer and interferes with my ability to brake quickly. Also, because I am so close…
The air bag light stays on contacted the dealer since a recall was issued before but was told recall has been closed this seems like a safety issue and the recall should not close, also the power seat switch on drivers side will not recline back seat adjusts forward and now is too far forward information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *kb *tr
Check engine light came on along with ESC off light showing up on dashboard. At times when starting vehicle up in morning vehicle would not accelerate, I've pressed the gas pedal to the floor and no acceleration. Sunroof window, back driver window and heated front seats have stopped working and my airbag lights stay on ?
Dashboard has outline airbag crack on passenger side. Driver seat moves forward, tilts forward, moves back while driving. *tr
