The failure pattern owners describe
The 2006 Azera is plagued by a constellation of electrical problems that emerge gradually and worsen over the vehicle's life. Most commonly, headlights and dashboard lights dim drastically when braking or downshifting—a pattern dealers have chased with battery and terminal cleaning for years without resolution, even though owners reference a TSB addressing the issue. Multiple owners report the dealer refuses to apply the TSB fix despite being shown it.
Owners describe a wider voltage instability: radios cut out and reset, door locks stop responding to fobs, rear window shades grind or move unprompted, and the AC temperature changes on its own. One owner's driver's seat back readjusts forward repeatedly while the car is in motion, crushing them against the steering wheel. Another has a chronic no-start requiring shifter manipulation; replacing the transmission inhibitor switch fixes it temporarily—six months to a year—then the problem returns.
Several engines stall while driving or shortly after restart. One case of loss of all electrical power while parked—no lights, no clicking, nothing—has been reported, and at least one vehicle caught fire while parked. A technician linked one stalling case to the cigarette lighter socket drawing too much power, suggesting a weak power distribution design.
Dealers frequently claim they cannot diagnose these issues, refuse to attempt repairs, or admit they've heard of the problem but can't remember the fix. The complaint pattern spans 25 reports across mileage from 20,000 to 135,000 miles.

Symptoms owners cite: Seat back moves forward involuntarily while parked; Seat back readjusts while driver is seated and vehicle is moving; Occupant compressed against steering wheel; Movement cannot be stopped until seat reaches full forward position; Difficult to reach brake pedal
Repairs/costs cited: Dealer could not determine cause; suspected switch. No confirmed repair noted.
Random no-start condition
Engine will not crank despite all dashboard lights and systems appearing normal. Owner must manipulate shifter to achieve start. Transmission inhibitor switch (park-sensing switch) identified as recurring culprit requiring replacement multiple times.
When: 56,000 to 80,000 miles noted; first repair lasted 1 year, second lasted 6–8 months before recurrence
Symptoms owners cite: No engine crank; No ignition noise or clicking; Dashboard lights operate normally; Vehicle appears ready to start but does not; Intermittent; shifter manipulation sometimes triggers start
Repairs/costs cited: Transmission inhibitor switch replaced twice by owner. First repair held ~1 year; second held 6–8 months. Dealer refused to attempt troubleshooting or parts replacement.
Headlight and instrument panel dimming under braking or deceleration
Headlights, dashboard lights, and other exterior lights dim drastically when braking or downshifting. Voltage drop in charging system. Issue worsens over time. Dealers have attributed to battery terminals, dead battery, or offered no solution despite repeated visits and TSB awareness.
When: Starting as early as 2008; reported multiple times per year; mileage range 20,000 to 135,000
Symptoms owners cite: Headlights dim while braking; Dashboard and instrument panel lights dim; Dimming occurs during downshift; High beams needed for adequate illumination at night; Dimming also visible in speedometer and gauge lights during day; Lights may flicker or turn on/off
Codes mentioned: TSB reference mentioned but TSB number not provided
Repairs/costs cited: Battery terminals cleaned; battery replaced; bulbs replaced—all ineffective. Dealers refuse to perform TSB-described fix. No confirmed resolution.
Recalls/TSBs owners mention: TSB exists for this issue (referenced by owner but not described in detail). Dealers aware but refuse to implement recommended repair.
Electrical system voltage instability and load-shedding
Chronic voltage drop causing multiple systems to behave erratically: headlights dim, radio cuts out or resets, dashboard lights flicker, AC temperature changes on its own, door locks malfunction, rear window shade activates unexpectedly. Alternator replacement does not resolve. Multiple unrelated symptoms suggest power distribution or ground issues rather than single component failure.
When: Develops gradually over vehicle lifetime; reported at 56,000 miles and beyond. More pronounced at lower speeds/idle.
Symptoms owners cite: Headlights flicker or dim; Radio loses volume or turns off then resets on restart; Dashboard lights flicker or turn on/off; Door locks do not respond to key fob; Rear window shade activates or operates erratically; AC temperature fluctuates; Speedometer and gauge lights dim; Engine stalls after restart or during driving; ABS warning light illuminates; Check engine light illuminates
