Is there a fix? Manufacturer service bulletins

The failure pattern owners describe
The 2015 Buick Encore has a well-documented passenger airbag sensor problem that keeps the system switched OFF even when occupied. Multiple owners say the sensor incorrectly interprets adult occupants as too light, refusing to activate for passengers weighing 135–180 lbs, even though a dealer's 220-lb mechanic can trigger it. One owner tested with a 200+ lb passenger plus a dog and still got the OFF indicator.
The sensor behavior is inconsistent—one day it works, the next day it won't, with the same person in the seat and no changes to vehicle condition. Some owners also report the driver airbag warning light staying on repeatedly, recurring even after dealer repairs and warranty expiration.
Most concerning: two owners describe actual collisions—head-on impact at 45–50 mph and a 35 mph side strike—where airbags did not deploy at all. GM issued a recall in September 2016, but owners report the fix did not address the underlying problem. GM's recall notification was inconsistent; one owner discovered it in the newspaper rather than through official channels.

Failure modes owners describe
Passenger Seat Airbag Sensor Malfunction
Passenger-side airbag sensor misreads occupant weight and incorrectly displays 'OFF' status. Sensor fails to activate airbag for adults weighing under 180-200 lbs, even though they exceed the weight threshold. Problem persists even after recall service.
When: January 2018 onward; ongoing since purchase in some cases
Symptoms owners cite: Passenger airbag OFF indicator illuminates with person sitting in seat; Airbag does not activate for occupants weighing 135-180 lbs; Airbag only activates for occupants over 200 lbs; Indicator stays ON regardless of motion or stationary state; Sensor inconsistently reads child-weight status for full-size adults
Repairs/costs cited: Dealer recommends new sensor replacement; no error codes reported by dealerships
Recalls/TSBs owners mention: Previous recall (September 2016) performed but did not resolve issue; GM indicated no good explanation for non-notification of recall
Intermittent Passenger Airbag Activation
Passenger airbag activation status is unpredictable and inconsistent, switching between ON and OFF regardless of occupant weight, vehicle motion, or seating position.
When: Intermittent; no specific timeframe reported
Symptoms owners cite: Airbag light turns on and off unpredictably with same passenger; Works one day and fails the next with no changes; Occurs whether car is moving or stationary; Behavior independent of occupant identity or weight
Driver Airbag Warning Light Recurrence
Driver-side airbag warning light illuminates repeatedly after service, with problem recurring multiple times over vehicle ownership.
When: First occurrence April 2017; recurred at least 4 times by time of complaint (warranty expired)
Symptoms owners cite: Driver airbag warning light stays on; Problem recurs after dealer service
Repairs/costs cited: Repaired three times under warranty; owner now facing out-of-pocket repair costs
Airbag Non-Deployment in Collision
Airbag system fails to deploy during high-impact frontal collisions at highway speeds, leaving occupants unprotected.
When: During collision events at 35-50 mph
Symptoms owners cite: Airbag does not deploy on head-on impact at approximately 45-50 mph; Airbag does not deploy on side-impact at 35 mph; Seatbelt does not lock (narrative #9)
Recalls/TSBs owners mention: Recall issued for this problem; however, owner reports recall service did not fix the issue
Airbag Light with Immobilization and No-Start Condition
Driver airbag warning light combined with immobilization light prevents vehicle from starting, creating a no-start condition.
When: Not specified in complaint
Symptoms owners cite: Driver airbag light stays on; Immobilization light illuminates; Vehicle will not start
Repairs/costs cited: Issues addressed by TSB according to complaint
Recalls/TSBs owners mention: TSB (Technical Service Bulletin) issued for this condition

Drivers airbag light stays on - immobilisation light stays on, car won't start. Both of these issues were addressed by TSB and complaints
There was a recall on the airbags as being unsafe. I contacted my dealer and asked for them to return my call so I could determine a solution to the unsafe situation. They have not contacted me back in any fashion.
A car pulled out in front of my wife. She struck the other vehicle in the driver's door. The airbag did not deploy and the seatbelt did not lock. This caused her injuries. There has been a recall for this problem. It did not fix the problem. The accident occurred in a 35 MPH zone and on a 4 lane road.
