Owners have filed 40 airbags 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.
Airbags accounts for 26% of all owner complaints filed against this vehicle, across 8 categories tracked.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags 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
The 2005 Suzuki Forenza shows a consistent cluster of airbag complaints: the warning light illuminates and stays on, often within the first year or shortly after purchase. Dealers reset it temporarily, but the light returns within weeks to months. Forty owners report this cycle repeating across multiple service visits—some making three, four, or five trips to the dealer without permanent fixes.
Several owners hit a warranty wall. Suzuki denied coverage under the 3-year/36,000-mile warranty despite these being early failures, calling them "out of warranty." Owners cite Service Bulletin TS050115B, suggesting Suzuki knew about the problem, yet no recall was issued.
Passenger airbag sensors malfunction in predictable ways: the "off" light stays illuminated even when a 100+ lb passenger sits down, or the sensor disengages if the passenger shifts position. One owner traced the cause to liquid spills into the cup holder, where Suzuki located the sensor—a poor design that led to failures at 30,000, 50,000, and higher mileages.
Most troubling are four collision reports where airbags did not deploy at speeds as low as 10 mph and as high as 50 mph. Injuries included facial trauma, broken teeth, neck and back trauma, and head injuries. Vehicles were destroyed; in some cases, the manufacturer was never even notified.
Diagnostics are vague: dealers often cannot pinpoint whether the fault is in the airbag itself, the sensor, wiring harness, or control module. Repairs attempted include terminal cleaning, cable tie removal, harness attachment, and temporary "unknown" remedies. Costs for replacement parts ran $1,500–$1,600.

Failure modes owners describe
Airbag warning light illumination (recurrent)
Airbag light comes on and stays illuminated, or illuminates intermittently. Dealers reset the light temporarily, but it returns within weeks to months. Multiple service attempts fail to resolve the issue permanently. Owners report uncertainty whether airbags will actually deploy when needed.
When: Reported from as early as a few months after purchase through 100,000+ miles; most common between 20,000–70,000 miles
Symptoms owners cite: Constant or intermittent airbag warning light on instrument panel; Light blinks twice then stays on; Light flickers on and off sporadically; Light goes off after dealer reset but returns within weeks to months; Owner uncertainty about whether airbags are functional
Codes mentioned: B1382 (Passenger side injector)
Repairs/costs cited: Dealers performed diagnostics but often could not identify cause. Repairs attempted included harness attachment under seat, cleaning of terminals, cable tie removal under seats, and temporary unknown remedies. Most repairs proved temporary or ineffective. Some owners charged $1,500–$1,600 for seat replacement.
Recalls/TSBs owners mention: Suzuki initially denied warranty coverage despite vehicle being within 3-year/36,000-mile warranty in some cases. Service Bulletin TS050115B referenced by owners but no recall issued. 'Out of warranty assistance' programs denied repairs. Some dealers stated warranty did not cover the problem.
Passenger side airbag sensor malfunction
Passenger side airbag off indicator illuminates incorrectly even when an adult is seated, or fails to illuminate when it should for light-weight passengers. Sensor located underneath cup holder is vulnerable to liquid spills. Sensor resets if passenger exits and car restarts but problem recurs.
When: Reported between 30,000–50,000 miles; some as early as first few months of ownership
Symptoms owners cite: Passenger airbag off light stays on despite adult (100+ lbs) sitting in seat; Light does not come on for children under 54 lbs as expected; Sensor disengages with slight seat movement; Sensor engages only if passenger already seated before engine start; Light resets when passenger exits and car restarts, then recurs
Repairs/costs cited: Sensor replaced in at least one case (at 48,000 miles). One owner reported condensation damage from beverages as cause (third failure in 2 years). Dealers stated sensor location under cup holder makes it vulnerable to spill damage. One dealer refused repair, stating nothing was wrong.
Recalls/TSBs owners mention: Suzuki told owner at 50,000 miles (just outside bumper-to-bumper warranty) repair was not covered. Service Bulletin TS050115B referenced. One dealer told owner airbag staying off was 'normal' for lighter-weight passengers.
Airbag deployment failure in collision
Frontal and/or side airbags failed to deploy when vehicles were struck at low to moderate speeds. Injuries sustained to head, neck, chest, back, face, legs, wrists, and knees. Multiple occupants injured across four separate incidents.
When: Incidents reported at 52,000 miles; 10 mph collision; 40 mph rear-end; 50 mph rear-end; and 120,000 miles
Symptoms owners cite: Frontal airbags did not deploy; Side airbags did not deploy; Both driver and passenger airbags inoperative in same vehicle; Multiple occupant injuries from steering wheel, dashboard, or direct impact
Repairs/costs cited: Vehicles were destroyed or towed; no repairs documented. One case noted vehicle never diagnosed or repaired.
Recalls/TSBs owners mention: Manufacturer not notified in multiple cases; one case where manufacturer was notified, no response documented.
Wiring harness and electrical faults
Wiring harness failure or connection errors detected as cause of airbag warning light. In one case, wire movement caused by driver seat adjustment triggered the light. Terminals showed high resistance requiring cleaning. Cable ties under seats removed as part of troubleshooting.
When: Failures identified between 20,000–70,000 miles
Symptoms owners cite: Airbag warning light illuminates; Connection errors detected by dealer
Repairs/costs cited: Terminals cleaned; cable ties under seats removed; harness cleaned or replaced. One dealer noted wiring harness failed and needed replacement at 70,000 miles. Repairs sometimes reduced resistance but light often remained on or recurred.
Airbag control module failure
Airbag control module failed in conjunction with seat sensor failure. Owner advised by dealer that both components required replacement.
When: Identified at 57,000 miles
Symptoms owners cite: Airbag warning light illuminated
Repairs/costs cited: Control module and seat sensor failure diagnosed; vehicle not repaired.
Recalls/TSBs owners mention: Manufacturer notified but offered no assistance.

Driver's airbag was fixed 2 or 3 times under warranty, and fixed one more time after warranty expired. The airbag light is on once again. *tr
From what I understand, the Suzuki forenza's airbag sensor (I have a 2005 Suzuki forenza) is under the cup holder and faults out easily due to condensation from beverages. Mine just went out for the 3rd time in 2 years. I contacted Suzuki, and they said I would have to pay for the repair since the vehicle has 50,000 miles and is out of the "bumper-to-bumper" warranty period. My airbag light on…
Air bag light stays on since 07-2014 approx. 55,000 miles on car at that time. Dealer says that there is not a recall and Suzuki will not cover under warrenty, but they will be happy to take my money. There is a service bulletin # ts050115b.its a safety issue that a lot of people are having.
