The failure pattern owners describe
2013 Azera owners describe a pattern of electrical and safety system failures. The most serious is an anti-lock brake system defect causing internal brake fluid leaks that create electrical shorts and engine compartment fires. Hyundai issued a recall in October 2023 warning owners to park outside away from structures, but as of April 2024 provided no remedy—one vehicle burned completely while parked; another caught fire while driven with the owner's wife at the wheel.
Airbag and occupant classification system (OCS) failures are widespread. Multiple owners report SRS warning lights staying on, triggered by diagnostic codes B1490 and B1763. The OCS sensors malfunction inconsistently based on passenger weight and position. One owner's vehicle fell just outside a recall window despite matching symptoms exactly.
Engine start intermittency affects multiple owners—pushing the start button produces only a soft buzzing or clicking under the hood; restarting 3–5 times eventually works. Owners found this is a known 2011–2013 Hyundai issue, but the dealer acknowledges no recall or technical bulletin exists.
Additional complaints include dashboard brightness problems, missing seatbelt warning chimes and turn signal sounds, and smoking while parked. Service departments have documented some issues but cannot or will not repair them, citing lack of bulletins or parts coverage.
