What stands out
Owners have filed 28 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.
No new NHTSA electrical complaint has been filed on this vehicle in over 18 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.

The failure pattern owners describe
Owners of the 2005 Forenza cite a consistent pattern: melted wiring and burned connectors in the multifunction switch and headlight control assembly. The failures typically show up as smoke from the dashboard left of the steering column, a burning plastic smell, and melted connectors that fuse wires together. In several cases, owners discovered burned wiring when the low beam stopped working entirely and high beams became the only option; technicians found plastic harness material also charred.
Multiple owners report that these melting failures occurred after dealership repairs under two related recalls (campaigns 07V452000, 12V397000, 14V262000 for exterior lighting and electrical wiring). One owner's vehicle caught fire at startup, destroying it; another's nearly ignited in the parking lot. The fires and smoke incidents happened at relatively low mileage—between 15,000 and 35,000 miles—suggesting a design or manufacturing flaw rather than wear.
Beyond the switch melting, owners describe intermittent no-start conditions that persist across seasons and multiple dealer visits, complete power loss while driving, blown cooling system fuses that destroy the radiator, intermittent shorts affecting the radio and brake lights, and airbag lights that stay on without cause. A few owners took vehicles back to dealers after initial recalls, only to have new electrical failures appear. One owner was told by Suzuki they would only cover the specific component named in the recall, not cascading damage—leaving the bill on the customer.

Failure modes owners describe
Melted wiring and burned connectors in multifunction switch / light switch assembly
Wiring harness and connectors in the headlight/multifunction switch assembly experience thermal failure, melting plastic and wire insulation. This occurs in the steering column area and beneath the dashboard. Multiple owners report discovering melted wires and burned plastic harness after smoke or burning smell, sometimes progressing to fire. The failure often follows dealership repair of recalled electrical components, suggesting repair-induced damage.
When: Reported from 2006 onward, often shortly after recalled repairs; mileage varies from 12,000 to 126,000
Symptoms owners cite: Smoke coming from dashboard area, especially left of steering column; Burning smell (plastic/electrical); Headlights and low beams not working or staying on unintentionally; Lights melted into connector; Interior fire in steering column or under dashboard; Radio and speakers failing after melting event; Trunk light blinking or staying on
Codes mentioned: Check Engine Light staying on
Repairs/costs cited: Part SM37420-85Z10 switch assembly and SM36620-85Z70 harness assembly replacement; estimated $1,570 at dealership in one case. Dealer noted 'internal failure within multifunction switch causing thermal melting of connectors at back of switch and wiring harness.' Some cases required complete wiring replacement and rerouting outside harness.
Recalls/TSBs owners mention: Recall campaign IDs 07V452000 (exterior lighting), 12V397000 (electrical system wiring), 14V262000 (exterior lighting/electrical system). Suzuki issued TSB and recall notices. In one case, manufacturer refused to cover damage from prior recall repair under new recall, stating they only cover components listed in the specific recall.
Low beam headlight failure / high beam only operation
Low beam headlights fail to illuminate; owners resort to driving on high beams only. Bulbs and fuses test good, pointing to wiring or switch failure. In some cases, internal wiring is found burned or cut and reattached outside the harness. Daytime running lights also frequently fail or work intermittently.
When: Occurred from 2005 onward; noted in early ownership and at various mileages
Symptoms owners cite: Low beam headlights out; only high beams functional; Daytime running lights not working or on/off inconsistently; Bulbs and fuses confirmed good but lights still do not work; Low beam wiring burnt or damaged; High beams coming on instead of low beams
Repairs/costs cited: Requires dashboard disassembly and access to wiring behind firewall/gauges. Burned wiring and plastic harness found; wiring cut and reattached outside harness. Light switch assembly replaced in some cases without resolving issue. Complete wiring harness replacement may be needed.
Recalls/TSBs owners mention: Suzuki technical service consulted in at least one case. Dealer indicated Suzuki was aware of the issue but had not issued recall due to lack of reported fire damage at that time.
Intermittent starting / no-start condition
Engine fails to start or starts only after multiple key turns and ignition cycling. Problem occurs across all seasons and temperatures, ruling out cold-weather causes. Dealers repeatedly cannot reproduce or diagnose the issue despite multiple visits. Some cases involve computer resets; others list alarm, battery, fuses, and ignition-related replacements without resolution.
When: From new vehicle ownership; current mileage 15,000–26,000 miles in reported cases
Symptoms owners cite: Engine does not respond to key turn; Key must be turned fully to OFF position and restarted; Vehicle hesitates and loses power during startup attempts; Check Engine Light illuminates; Problem occurs in summer, fall, winter, and spring
Codes mentioned: Check Engine Light
Repairs/costs cited: Dealers replaced alarm, battery, fuses, radio, daytime running lights, and ignition fuses without resolving issue. Computer component updated in one case. No permanent fix documented.
Complete loss of power while driving
Vehicle loses all electrical power while in motion, including engine power, forcing the vehicle to stall in traffic or at intersections. Starting issues also reported alongside power loss. Problem occurs after recall repair in at least one case.
When: Reported at approximately 33,000 miles in one case; timing unclear in others
Symptoms owners cite: Complete loss of power while driving through intersection; Vehicle stalls without warning; Starting issues persist; Electrical system failure
Repairs/costs cited: Dealer could not determine cause of failure. Occurred after vehicle was repaired under NHTSA campaigns 14V262000 and 12V397000.
Recalls/TSBs owners mention: Recalls 14V262000 and 12V397000 applied; manufacturer notified but no resolution documented.
Vehicle fire (electrical source)
Vehicle catches fire due to electrical fault, typically in the steering column area or under the dashboard. Fires have occurred both while driving and while parked. In one case, fire occurred at startup; in another, fire broke out moments after owner left the vehicle parked. No warning lights or prior incidents in some cases.
When: Reported from 2006 onward; mileages 15,000–32,000 miles
Symptoms owners cite: Interior fire in steering column or dashboard; No prior warning indicator lights in some cases; Smoke from under dashboard
Repairs/costs cited: Vehicles destroyed by fire. Fire department determined electrical cause. One vehicle destroyed at 15,000 miles; owner received recall notice after fire occurred.
Recalls/TSBs owners mention: Recall notices received after fires in some cases (campaign numbers unknown for some). One fire destroyed vehicle; another nearly caused property damage to adjacent cars and house.
Cooling system fuse failure and overheating
Cooling system fuse blows repeatedly, causing radiator to fail or explode. Problem persists after radiator and fan replacement. Multiple mechanics unable to diagnose. Fuse blows immediately upon starting car in worst cases, suggesting internal short or fault in cooling circuit wiring.
When: Reported at undisclosed mileage
Symptoms owners cite: Cooling system fuse blows; Radiator fails or explodes; Engine overheating when stopping; Fuse blows as soon as key is turned to start
Repairs/costs cited: Radiator replaced; both cooling system fans replaced; relays checked. Three different mechanics unable to determine root cause.
Airbag warning light on; airbag sensor failure
Airbag warning light illuminates and remains on without any accident or apparent cause. In one case, airbag sensor system required replacement. Wiring for airbags replaced once in another case without resolving issue. Problem occurs at owner expense after warranty expiration.
When: Reported from 2006 onward; noted on vehicle owned from 2006 and at 12,000 miles in one case
Symptoms owners cite: Airbag warning light on continuously; Light remains on without accident or reason; Key cannot be removed from ignition (in related case)
Repairs/costs cited: Airbag sensor system replaced at owner expense (no cost provided). Airbag wiring replaced once; issue persisted.
Recalls/TSBs owners mention: Suzuki stated sensor failure was out of warranty and manufacturer not responsible. Recalls 12V397000 and 14V262000 relate to electrical issues but airbag coverage unclear.
Intermittent electrical shorts affecting multiple circuits
Electrical system exhibits intermittent shorts affecting radio, brake lights, HVAC, and other circuits. Symptoms worsen when door is closed or vehicle hits bump, suggesting loose or damaged connections. Battery replaced multiple times due to parasitic drain from interior trunk light.
When: Reported from early ownership; noted within first year of purchase
Symptoms owners cite: Radio shortness or cutting out; Brake lights intermittently not working; AC and heat not working when turned on, but work when door is opened or over bump; Interior trunk light remains illuminated; Battery drain requiring multiple replacements
Repairs/costs cited: Battery replaced on more than two occasions. Exposed wires found near steering wheel after recall service. Dashboard not secured.
Recalls/TSBs owners mention: Failures reported to manufacturer after recall service (campaign 14V262000). Exposed wires and unsecured dashboard noted after service.
Engine stall during driving
Engine stalls unexpectedly while vehicle is in motion at various speeds, without warning. Accompanied by foul odor from vents in one case. Problem recurs but was not diagnosed or repaired.
When: Mileage unknown
Symptoms owners cite: Engine stalls without warning while driving; Foul odor emitting through vents
Repairs/costs cited: Vehicle not diagnosed or repaired.
Recalls/TSBs owners mention: Manufacturer not notified.
