What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 21 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
ServiceNews Article - The clock shows the incorrect time. This issue is due to a limited GPS receiver capacity resulting in "rollover" of the internal chip memory; the "rollover" will occur on January 1, 2022, at 12:00AM local time. As a result, the navigation date and time will be incorrect.

The failure pattern owners describe
Owners describe two major electrical problems on the 2005 Acura RL that create real safety risks.
The most widespread complaint involves the Active Front Lighting (AFS) HID headlight system. Headlights flicker, cut out during night driving, and sometimes both go dark at once. One owner reports replacing ballasts at a cost of $500–$1,200. The issue happens frequently enough that owners have to repeatedly turn headlights off and back on to regain function. Owners note this problem is widespread among 2005–2006 model-year RL owners they found on forums. The AFS indicator light also illuminates erratically.
The second critical failure is unexpected total electrical loss while driving. One owner lost all power at 30 mph on a city street, unable to open doors, lower windows, or activate flashers—a hazardous situation requiring a bystander to loosen a battery cable. Another owner experienced complete power loss with no steering, engine shutdown, and all dash lights off; power returned after seconds to a minute, but the transmission showed wrong-gear errors and multiple fault messages. That dealer confirmed the car was "extremely dangerous to drive" but couldn't identify the root cause despite a month of diagnostics. A loose battery connection was found in at least one case.
Additional electrical failures include a door handle fire that melted through the exterior panel, keyless door-lock sensors corrupted by moisture, and a blank center navigation/display screen that controls vehicle systems. One owner reports a yaw-rate sensor under the center dash was defective, triggering SH-AWD and VSA warning lights.
Failure modes owners describe
Active Front Lighting (AFS) HID headlight flicker and shutdown
HID headlights flicker intermittently and cut out completely during night driving, affecting one or both lights randomly. Requires repeated on/off cycling of headlight switch to restore function. AFS indicator light illuminates unpredictably. Issue is widespread among 2005–2006 RL owners per owner forum research.
When: Occurs during night driving, sometimes triggered by curves or rough pavement; one owner notes it's unrelated to vehicle speed or conditions
Symptoms owners cite: Headlights flicker intermittently; One or both headlights cut out completely; Require manual off/on cycling to restore function; AFS indicator light illuminates randomly
Codes mentioned: AFS malfunction indicator
Repairs/costs cited: Ballast replacement cost cited as $500–$1,200; dealer suggests replacement of 'all active components' at owner expense
Total electrical system loss while driving
Complete loss of electrical power while vehicle is in motion, causing engine shutdown, loss of power steering, and all dashboard lights extinguishing. Power returns after seconds to a minute, followed by multiple fault codes and transmission gear errors. One incident involved loose battery cable terminal; another defied diagnostic identification after one month of dealer troubleshooting.
When: Occurred at 30 mph in traffic in one case; another case during normal operation
Symptoms owners cite: Engine stops abruptly; All electrical systems shut down; Power steering loss; Unable to open doors or lower windows; All dashboard lights off; Multiple fault codes appear after power returns; Transmission shows incorrect gear after restart
Codes mentioned: SH-AWD warning light, VSA warning light
Repairs/costs cited: One case: loose battery cable terminal; another case: undiagnosed after one month of dealer service
Door handle electrical fire
Electrical fire originating in driver-side door panel melted completely through the outside door handle. Owner found similar incidents reported on forums with no recall issued.
When: Occurred while vehicle was stationary in one case; timing unclear in other case
Symptoms owners cite: Smoke visible from door panel; Exterior door handle melted; Fire in door electrical components
Keyless entry door-lock sensor failure
Door-handle keyless access system fails to lock vehicle when button on driver door handle is pressed. Unlock function via handle pull still works. Owner found service bulletin citing moisture intrusion into door-handle sensors as cause.
When: No mileage given; owner references applicable service bulletin
Symptoms owners cite: Lock button on door handle does not lock vehicle; Unlock via door handle pull still functions; Must use key fob to lock vehicle
Recalls/TSBs owners mention: Service bulletin exists identifying moisture/weather damage to door-handle sensors as known issue
Center navigation/display screen failure
Display screen that controls vehicle electrical system functions goes completely blank (black), rendering vehicle adjustments and navigation inoperable. One owner reports navigation screen 'totally failed' along with yaw-rate sensor defect.
When: Failure occurred shortly after vehicle purchase in one case; no mileage given in another
Symptoms owners cite: Center display screen blank/black; Unable to adjust vehicle settings via display; Navigation system inoperable; GPS display does not work; Clock display does not work
Codes mentioned: Yaw-rate sensor defect (related failure)

Common questions
How serious is the electrical problem on the 2005 Acura RL?
It's a meaningful issue. 16 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $850.
At what mileage does the electrical typically fail?
Across the 12 complaints that reported odometer mileage, most electrical failures cluster between 57,000 and 161,000 miles, with the median around 70,000. A quarter of owners report trouble before 57,000; a quarter make it past 161,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
