I took my car to dealer to work on 3 recall notices on driver side airbag (not takata related since it's not a takata airbag), passenger side airbag, and seat belt. I also had a srs warning light that was on constantly for about 2 years so I had the dealer diagnose the warning light. The code showed 11-21 (something about open or increased resistance on the airbag). The dealer said the airbag needs to be replaced for about $1200 and the problem was caused by tampering with the airbag wiring. This totally did not make sense since I am the original owner and nobody tampered with the airbag. The light started to come on after 5-6 years since I owned the vehicle and the car was never involved in an accident. This looks like a poor quality air bag was used when the vehicle was made and I think Honda should replace this airbag at their cost.
