A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- [SA\-026\-24b](/bulletins/11011139.md), 2024-12-04, Service bulletin: AIR BAGS. A customer may complain of a rattle noise from the right side of the dash. The noise may be coming from the passenger side airbag.
- [SA\-026\-24](/bulletins/10254098.md), 2024-05-03, Service bulletin: AIR BAGS. A customer may complain of a rattle noise from the right side of the dash. The noise may be coming from the passenger side airbag.
- [08\-003\-23a](/bulletins/10240372.md), 2023-08-03, Service bulletin: AIR BAGS. Some vehicles may exhibit that the air bag warning light turns on or repeats cycles of turning on and off with DTC B1126:13 and/or B1127:13 stored in memory. B1126:13 \- Driver\-side side air bag module circuit open circuit or resistance high B1127:13 \- Passenger\-side side air bag module circuit open circuit or resistance high This issue is caused by any of the following: When the driver or passenger moves, a load is applied to the seat back and the load may cause displacement of the mating terminals in the side air bag module connector, resulting in insufficient contact and higher resistance. The DTC detection level is too sensitive. The form of the female terminals in the side air bag module connector may cause insufficient contact and higher resistance. To eliminate these concerns, \(1\) the DTC detection level of the SAS control module has been optimized, \(2\) the design of the side air bag module connector has been modified, and \(3\) the layout of the side air bag module connector has been modified.
- [08\-004\-23](/bulletins/10238667.md), 2023-07-05, Service bulletin: AIR BAGS; STEERING. Some vehicles with the two\-step deployment control air bag module may exhibit a clicking sound when turning the steering wheel. This is caused by the horn spring \(1\) of the airbag module interfering with the black color tape \(2\) of the clock spring harness \(3\), resulting in a stick\-slip noise \(click on attached sound file below\).
