ServiceNews Article - There are several possible causes for the SRS DTC U3000-49 (Internal Failure of the SRS Unit) to be stored. If you can duplicate the DTC, the troubleshooting will take you through the step-by-step process in isolating the faulty component. In most situations, the SRS Unit should be last on the list of components to replace. Here is a quick tip for troubleshooting a faulty seat weight sensor.

What stands out
Owners have filed 26 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.
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 26 complaints cluster around two main problems. First, a critical parts shortage tied to NHTSA recall 24V064000 (Seat Weight Sensor Safety Recall, issued February 2024) has left vehicles unrepaired for 15+ months. Owners report calling dealerships repeatedly only to hear parts are unavailable and won't arrive until December 2025 or later; Honda distributes parts to select dealers in limited quantities, and some dealers won't service the recall unless the warning light is already illuminated. Owners express anger at being told they must wait until someone is injured before Honda will prioritize the repair.
Second, several owners report actual airbag system failures: one owner was in a 35 mph frontal crash where airbags did not deploy despite recording false deployment in the computer—a mismatch suggesting control module or sensor malfunction. Another owner's curb strike triggered a curtain airbag deployment even though the same sensor had been serviced under recall months prior. One vehicle experienced airbag deployment alongside uncontrolled acceleration and steering lockout. Owners also report the SRS warning light illuminating at normal mileage (41,000–45,000 miles), with repairs denied by warranty and quoted at $2,000–$3,300 out-of-pocket for SRS unit, seat frame, and labor. No manufacturer response or assistance is documented in most complaints.
Failure modes owners describe
Non-deployment in frontal crash with false system recording
Airbags failed to deploy during a 35 mph frontal collision, but the vehicle's computer recorded a deployment event that did not physically occur. Post-accident diagnostics showed this discrepancy, and an SRS Problem warning appeared on the instrument cluster.
When: February 3, 2026; collision impact
Symptoms owners cite: Airbags did not deploy during frontal impact; Vehicle computer recorded false deployment; SRS Problem warning light displayed post-accident
Repairs/costs cited: Vehicle at body shop; available for inspection. Damage estimate over $8,000.
Seat weight sensor failure / SRS light illumination
Passenger-side seat weight sensor malfunction triggers SRS warning light. Related to NHTSA Campaign 24V064000 (2020-22 Multi-Model Seat Weight Sensor Safety Recall, announced February 6, 2024). Owners report being told replacement parts have been unavailable for extended periods, some waiting 17+ months since recall notice. Repairs quoted at $2,000–$3,300 out-of-pocket when warranty does not cover.
When: Reported at 41,000–45,000 miles; recall notice issued February 2024
Symptoms owners cite: SRS warning light illuminated; SRS system failure message displayed; Passenger seat weight sensor diagnostic fault
Codes mentioned: 24V064000
Repairs/costs cited: Replacement parts unavailable; typical repair cost $2,000–$3,300 including SRS unit ($531.69), seat frame ($1,398.98), and labor ($980.75). Owners report warranty denial.
Recalls/TSBs owners mention: NHTSA Campaign 24V064000 issued February 1, 2024 for 2020-22 Multi-Model Seat Weight Sensor recall. Honda issued STOP SALE on affected vehicles. Parts remain unavailable at multiple dealerships as of mid-2025; Honda stated parts would be in stock April 2025 but then out of stock again. No parts distribution reported to owners.
Unexpected airbag deployment while vehicle in motion
Right-side curtain airbag deployed while vehicle was being driven at low speed (approximately 40 mph) after the vehicle swerved and struck a curb. Owner reports this vehicle had previously been serviced at Honda dealership for a related sensor issue under safety recall, with sensor purportedly replaced.
When: During low-speed swerve incident after curb strike
Symptoms owners cite: Right side curtain airbag deployed; Deployment occurred at low speed (40 mph) during swerve
Repairs/costs cited: Owner requesting inspection and repair at no cost by Honda dealership. No repair completion noted.
Recalls/TSBs owners mention: Sensor purportedly replaced under prior recall at Honda dealership in Waco, Texas; issue recurred despite prior service.
Airbag deployment during uncontrolled acceleration event
Airbags deployed after vehicle experienced uncontrolled acceleration with stuck accelerator pedal and unresponsive brakes, resulting in collision with sidewalk. Driver confirmed accelerator was not depressed intentionally. Passenger side suspension, control arm, and axle were damaged.
When: During driving incident; mileage approximately 47,395
Symptoms owners cite: Accelerator pedal stuck / malfunctioned; Brakes did not respond; Airbags deployed on impact
Repairs/costs cited: Passenger side suspension, control arm, and axel broken. Diagnosis unknown at dealer; vehicle not repaired.
Recalls/TSBs owners mention: Manufacturer notified; offered no assistance and referred owner to NHTSA Hotline.
Airbag deployment with steering lock during motion
While vehicle was moving on road at 20–25 mph, steering wheel locked out and airbags deployed simultaneously due to system malfunction. Driver was unable to control vehicle and struck a parked car. Incident occurred in residential area and was inspected by city police. Owner also reports separate incidents of vehicle shutdown with beeping sounds when stopped at red lights.
When: During driving on residential street at 20–25 mph
Symptoms owners cite: Steering wheel suddenly locked; Airbags deployed while vehicle in motion; Loss of vehicle control
Repairs/costs cited: Incident inspected by city police. Mentioned to service center for unrelated auto feature malfunctions (shutdown, beeping).
Recall parts unavailability — extended delay
Owners received recall notification for NHTSA Campaign 24V064000 (Seat Weight Sensor Safety Recall) in early 2024. Multiple dealers report replacement parts unavailable continuously through mid-2025 — delays of 15+ months. Dealers state parts are only being distributed to select dealers and are not available for ordering. Honda stated in some cases that dealer must first have warning light illuminated before servicing recall. This creates a situation where owners cannot have a safety recall completed and manufacturers cannot fulfill recall obligation due to parts shortage.
When: Recall notice February 2024; parts unavailable through mid-2025
Symptoms owners cite: Parts unavailable at dealerships; Multiple calls to dealers over months with no resolution; Dealers told to call back in 2–3 weeks repeatedly; Some dealers claim alert light must be present before recall service allowed; Parts listed as coming from Honda USA in limited quantities
Codes mentioned: 24V064000
Repairs/costs cited: No repairs completed due to parts shortage. Owners unable to have recall serviced despite recall notification.
Recalls/TSBs owners mention: NHTSA Campaign 24V064000 issued February 1, 2024. Honda issued STOP SALE on affected vehicles. Honda stated parts would be available; however, dealers have not received inventory. One complaint notes Honda opened a case; others report no manufacturer response to parts delay complaints.
