The failure pattern owners describe

Engine fires are the most serious complaint: two owners describe flames and smoke in the engine compartment, with one fire requiring fire department response. One owner links the fire to rodent damage on soy-based wire insulation; another experienced a fire even after the dealer replaced the alternator, starter, and engine wiring harness over 8-9 days.

Power loss and stalling occur frequently during driving, often at highway speeds. Owners report the vehicle failing to accelerate, hesitating as if about to stall, or shutting down completely. Check engine lights typically illuminate, sometimes accompanied by battery or oil warnings. Several owners tried fixes—crank sensor, plugs, catalytic converter—that worked temporarily but the problem returned.

Door lock actuators are a widespread chronic issue. Three or four actuators fail individually over six years or more, with owners forced to lock doors manually. Honda covered the first failure under warranty but refused to cover subsequent ones. One owner in 35 years of Honda ownership had never seen this before.

Door locks also cycle erratically—locking and unlocking on their own while driving, especially when accelerating from a stop or turning. This creates both a safety and annoyance problem with children in the vehicle.

Ignition and starting produce grinding or sparking sounds on key insertion, typically worse in cold weather. Some owners describe violent shaking and stuttering during driving along with loss of power. Spark plugs and ignition coils require frequent replacement—one owner replaced them twice in two years.

Airbag sensors malfunction; one owner's sensor wire broke during normal seat adjustment, leaving the warning light on indefinitely with no way to verify airbag function in a crash. Seat belt warning systems fail similarly. A fuse box problem triggered unexpected horn activation at 2 AM while the vehicle sat parked and unattended, followed by multiple safety warning lights.

Failure modes owners describe

Engine compartment fire

Owners report flames and smoke originating from the alternator, lower engine area, and front center of hood. One owner attributes the fire to rodent damage to soy-based wire insulation; another experienced fire after alternator and starter replacement and subsequent engine wiring replacement did not resolve the issue.

When: One incident reported; another involved multiple attempts to repair over 8-9 days

Symptoms owners cite: Flames visible from hood; Smoke from alternator area; Smoke from lower engine compartment

Repairs/costs cited: Alternator and starter replacement attempted; engine wiring replacement attempted but did not resolve fire risk. Fire extinguisher required to suppress flames. Towing and dealership/independent shop involvement.

Recalls/TSBs owners mention: Honda case opened (case number redacted) on 10/8/2024 to document engine fire after owner contacted 800-999-1009

Ignition and starting issues

Multiple owners report ignition failures, grinding or sparking sounds when turning the key, and rough running or stalling on startup. Symptoms suggest intermittent electrical contact or starter engagement problems.

When: 36,000 miles (sparking); first start conditions (grinding, worse in cold)

Symptoms owners cite: Ignition failed to engage properly; Sparking noise when key inserted; Grinding noise when turning key; Rough running on cold starts; Vehicle hesitates as if it would stall after ignition

Repairs/costs cited: No repairs documented in narratives

Stalling and power loss during driving

Owners report the vehicle stalling while driving, loss of power when accelerating, and hesitation as if the vehicle would stall. Check engine light and battery/oil warning lights frequently illuminated. Some owners reference NHTSA campaign 11V004000 (Electrical System) but were not included.

When: 60,000 miles; 97,000 miles; 106,000 miles; 160,000 miles

Symptoms owners cite: Vehicle stalls while driving at highway speed; Loss of power on acceleration; Hesitation during acceleration; Violent shaking and stuttering; Check engine light illuminated; Battery and oil warning lights illuminated; Vehicle fails to increase speed despite depressed accelerator

Codes mentioned: Check engine

Repairs/costs cited: Crank sensor, spark plugs, and catalytic converter replaced; repairs effective for approximately one year before recurrence. One case: engine wiring harness and driver-side under-dash fuse box required replacement.

Recalls/TSBs owners mention: NHTSA Campaign 11V004000 (Electrical System) cited by owners but their vehicles not included in recall

Door lock actuator failure

Multiple owners report door lock actuators failing to lock or unlock doors properly. Three of four doors affected in some cases, requiring manual operation. Actuators fail individually over time, with one owner experiencing all four failures within a six-year period.

When: Approximately 3-7 years of ownership; failures occur individually about one year apart

Symptoms owners cite: Doors fail to lock via power lock button; Doors fail to unlock via interior unlock button; Manual lock operation required; Intermittent or complete loss of function on multiple doors

Repairs/costs cited: Replacement of door lock actuators required (three or four units depending on failure extent)

Recalls/TSBs owners mention: Honda covered first actuator failure under warranty; refused to cover subsequent failures despite owner request to replace all actuators simultaneously

Power door locks cycling during driving

Owners report door locks automatically locking and unlocking while the vehicle is in motion. Problem occurs when pressing the accelerator after a stop or when making turns. One owner reports this began immediately after purchase.

When: Occurs during acceleration from stops and during turning

Symptoms owners cite: Locks engage and disengage repeatedly while driving; Locks cycle when accelerator is pressed; Locks unlock when making turns; Cabin lights cycle on and off with lock operation

Repairs/costs cited: No repairs documented

Airbag sensor and warning system issues

One owner reports airbag sensor wire broke during normal seat adjustment, causing persistent airbag warning light. Another owner reports passenger airbag indicator going on and off. Airbag warning light remaining illuminated creates uncertainty about airbag function in a crash.

When: Early in ownership; intermittent recurrence

Symptoms owners cite: Airbag warning light continuously illuminated; Airbag sensor wire breakage; Passenger airbag indicator fluctuating

Codes mentioned: Airbag warning light

Repairs/costs cited: Airbag sensor wire replacement quoted at over $400; another independent shop opinion cited normal wire breakage from use rather than owner damage

Recalls/TSBs owners mention: Honda refused warranty coverage on sensor wire replacement, claiming wire appeared cut; vehicle out of warranty

Tail light and electrical short circuit failures

Owner reports tail lights shorting out and failing to illuminate randomly. Another reports multiple electrical components failing, including brake warning lights staying on (related to ABS modular malfunction).

When: Approximately 60,000 miles (ignition failure case with tail lights); intermittent

Symptoms owners cite: Tail lights short out; Tail lights fail to illuminate; Multiple safety warning lights illuminated; Brake warning lights remain on

Codes mentioned: Brake warning, ABS warning

Repairs/costs cited: Fuse box replacement documented in one case; no specific parts for tail light shorts documented

Automatic window operation malfunction

Owner discovered that turning the key twice in the ignition (or holding the unlock button on remote for 10 seconds on the second push) causes all four windows to open automatically, regardless of lock status. This is a design feature per the owner's manual but represents a potential security risk.

When: Early ownership (3,200 miles)

Symptoms owners cite: All four windows roll down unintentionally; Automatic operation triggered by key double-turn or extended unlock button hold; Vehicle left unsecured when parked

Repairs/costs cited: Dealer reprogrammed unlock remote to resolve

Recalls/TSBs owners mention: Feature noted in owner's manual; dealer reprogramming resolved issue

Horn malfunction and unexpected activation

Owner reports car horn sounding spontaneously for approximately 10 minutes at 2 AM while vehicle was parked and unattended, repeating twice before stopping when door was unlocked. Subsequent startup showed multiple safety warning lights.

When: February 10, 2017
