What stands out
Owners have filed 39 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
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, once specific triggers are met, the navigation date and time will be incorrect.

The failure pattern owners describe
Owners report a cluster of electrical and battery issues that span from low mileage to well beyond 100,000 miles. The most widespread complaint involves headlights flashing or dimming every 27–30 seconds when the air conditioning or heater fan engages. Multiple owners have taken their vehicles to dealers, where service departments confirmed the behavior occurs on other 2009 Accords but labeled it "normal" to save fuel. Owners do not find this explanation acceptable and view the strobe-like flashing as a safety hazard.
Battery problems appear frequently: parasitic drain forces some owners to pull fuses when the vehicle sits idle, since the battery will die within hours. One owner cycled through three batteries in eighteen months despite all of them testing good. Another owner's battery terminals corroded and failed, hidden under a plastic cover until the vehicle wouldn't start.
Alternators fail and sometimes recur—one owner replaced it four times, and another discovered oil contamination from the Variable Valve Timing solenoid assembly above the alternator causing the failure.
Door locks and anti-theft systems malfunction sporadically, trapping occupants inside the vehicle. Power windows open and close on their own, and one window motor ran continuously when the key was in the ignition, creating a fire hazard. Key fobs work intermittently, and courtesy lights fail to illuminate automatically.
Some owners report electrical system stalls, unexplained warning lights, dashboard lights too dim to read or missing entirely, and TPMS warnings despite normal tire pressure. One incident of unintended acceleration led to a collision and fuel tank rupture.

Failure modes owners describe
Headlight flashing/dimming with A/C activation
Headlights blink or dim when air conditioning or heater fan is turned on. Occurs every 27-30 seconds. Multiple owners report dealer acknowledgment that this is 'normal' for the model to save fuel, but owners consider it a safety hazard and distraction.
When: Starting from early ownership (12,500 miles reported)
Symptoms owners cite: headlights flicker or blink when A/C activated; lights dim when defrost or A/C engaged; pattern repeats every 27-30 seconds; stops when A/C turned off
Repairs/costs cited: Dealers refuse repair, claim it is normal characteristic to save fuel.
Recalls/TSBs owners mention: Honda refuses to run a campaign until sufficient complaints received; acknowledged as design issue by at least one dealer but no recall or TSB mentioned
Parasitic battery drain
Battery drains to dead within hours when vehicle is not in use. Owners report having to pull fuses to prevent complete discharge. Problem escalates over time. One owner replaced battery three times in 1.5 years despite all batteries testing good.
When: Recurring throughout ownership; worsens over time
Symptoms owners cite: battery dies within hours when parked; requires multiple jump starts; multiple battery replacements; battery discharges even in less than one minute with key in ignition; problem present when vehicle was purchased (one report)
Repairs/costs cited: Owners resort to pulling fuses manually to disable parasitic draw, which disables radio and some dashboard functions. No factory fix identified in narratives.
Alternator failure and recurrence
Alternator fails, sometimes multiple times. One owner replaced alternator four times. Another owner's alternator was contaminated with oil from the Variable Valve Timing (VVT) solenoid assembly located above it, requiring replacement of the VVT assembly to prevent repeat failure.
When: 70,000-70,950 miles reported for initial failures
Symptoms owners cite: vehicle shuts off without warning while driving; alternator not charging battery; alternator contaminated with oil from VVT solenoid
Repairs/costs cited: Alternator replaced. VVT solenoid assembly may need replacement to prevent oil leak contaminating replacement alternator.
Recalls/TSBs owners mention: One owner reports manufacturer offered no further assistance after multiple failures.
Battery post/terminal failure and corrosion
Battery positive terminal connection corrodes and fails. One report of battery wires separating due to failed post. Corrosion covered by plastic cover, making early detection impossible until vehicle fails to start.
When: 70,000 miles (one reported failure); timing variable
Symptoms owners cite: car will not start; corrosion on battery positive connection hidden under plastic cover; battery wires separate
Repairs/costs cited: Battery replaced.
Door lock failures and anti-theft system malfunction
Door locks fail to open manually or via remote. Anti-theft system engages unexpectedly, trapping occupants inside vehicle. One incident at 90-degree day forced owner to break windshield to escape. Problem recurs multiple times for at least one owner.
When: Recurring; one incident at stationary vehicle with engine off
Symptoms owners cite: door locks fail to open with key button; doors remain locked despite repeated button pressing; anti-theft system engages spontaneously; doors eventually unlock after repeated attempts; occupants trapped inside
Repairs/costs cited: One owner required windshield replacement to exit vehicle. Anti-theft system replacement was recommended but not completed.
Window and sunroof unintended operation
Power windows and sunroof open on their own without owner activation. Keyless remote activates without assistance. Four automated windows released independently while vehicle parked and unoccupied.
When: Low mileage (3,000 miles reported); also at higher mileages
Symptoms owners cite: windows open without owner assistance; sunroof opens without owner activation; keyless remote activates spontaneously; four windows and four doors unlocked without owner input
Power window motor failure
Power window motors fail, preventing windows from rolling up or down. Motors get extremely hot and run continuously when key is in ignition, creating potential fire hazard. Melted molding reported on one vehicle.
When: Various mileages reported
Symptoms owners cite: window motor fails to operate; window will not roll up or down; motor runs continuously when engine on; motor becomes very hot; window opens on its own while driving; molding near window melts from heat
Repairs/costs cited: Owner disconnected motor manually; dealer blamed aftermarket window tinting despite identical tinting on other windows.
SRS/airbag system faults
SRS warning light illuminates. One owner's airbag light remained on after recall module replacement. Open circuit wiring harness defect causes increased resistance in driver-side airbag circuit. One owner reports SRS module failure not covered under recall eligibility.
When: 60,000 miles and higher; one incident after recall completion
Symptoms owners cite: SRS warning light remains on; airbag light on after recall service; SRS light and TPMS light appeared at same time
Codes mentioned: open circuit wiring harness (driver-side airbag)
Repairs/costs cited: Wiring harness replacement recommended. One vehicle not repaired. Recall module completed on another vehicle but light remained on.
Recalls/TSBs owners mention: Recall for SRS module completed on at least one vehicle (2008-2010 model year range acknowledged); some 2009 models reported as ineligible for recall despite acknowledged problem.
Remote start malfunction and fuse failure
Remote start installed by authorized dealer representative causes main fuse to blow twice, requiring vehicle to be towed. Wire in remote start circuit blown fuse.
When: November 2011 and December 2011 (within first few years)
Symptoms owners cite: vehicle unable to start; main fuse blown
Repairs/costs cited: Main fuse replaced twice. Second repair cost owner $241.31.
Recalls/TSBs owners mention: Extended warranty refused to honor repair because dealer incorrectly claimed remote start was aftermarket, despite evidence it was installed by authorized representative.
Key fob intermittent malfunction
Key fob works intermittently, failing to lock/unlock doors or open trunk reliably.
Symptoms owners cite: key fob does not work reliably; remote key will not unlock doors; remote key will not lock doors; trunk remote malfunction
Repairs/costs cited: Repair cost $160.00.
Courtesy light automatic operation failure
Driver-side courtesy light fails to turn on automatically when door opens or remote unlock used, despite switch set to door mode. Light functions when manually pressed.
Symptoms owners cite: courtesy light will not auto-illuminate on door open; courtesy light will not auto-illuminate on remote unlock; light works when manually pressed; all other lights function normally
Repairs/costs cited: Bulb, fuse, and door-light switch tested and confirmed working.
Dashboard light visibility and function issues
Dashboard lights barely visible during daylight. Some dashboard light indicators missing or blinking. Radio, climate control, and shifter button displays missing.
When: 48,000 miles and higher
Symptoms owners cite: dashboard lights hardly visible in daylight; dashboard electrical components blink while driving; radio display missing or blinking; climate control display missing or blinking; shifter button display missing or blinking
Recalls/TSBs owners mention: Dealer acknowledged visibility issue as design defect but refused repair.
TPMS warning light false activation
TPMS (Tire Pressure Monitoring System) warning light appears despite normal tire pressure. Light remains on for extended periods.
Symptoms owners cite: TPMS light illuminated; tire pressure verified as normal; light remains on for multiple days
Engine stall and electrical system malfunction
Vehicle stalls while driving with unknown warning lights illuminated. Multiple independent mechanics unable to diagnose. Suspected electrical system failure.
When: 147,000 miles
Symptoms owners cite: vehicle stalls while driving; multiple unknown warning lights illuminated
Repairs/costs cited: Three independent mechanics unable to determine cause; suspected faulty electrical system.
Engine surge and unintended acceleration
Engine surged and vehicle sped up on its own while pulling into parking lot. Led to collision with boulders and railroad ties, ruptured fuel tank with fuel gushing onto ground. Two elderly occupants sustained spine injuries.
When: Specific mileage not reported
Symptoms owners cite: engine surge; vehicle accelerated on its own; vehicle sped up without driver input
Repairs/costs cited: Vehicle required extensive damage repair (front, rear, undercarriage, fuel tank rupture).
Melted battery from internal failure
Battery melted while driving at highway speed. Preceded by loud abnormal sound from under hood, gear skipping, vehicle lunge, burning chemical odor, and check engine light. Hairline fracture in engine housing had caused oil leak and oil seal fracture. Engine housing was replaced but electrical failure resulted in melted battery.
When: 84,000 miles
Symptoms owners cite: loud abnormal sound from under hood; vehicle skipped gears and lunged forward; burning chemical odor while driving 70-75 MPH; check engine warning light illuminated; battery melted
