While driving my 2021 Honda Civic Sport, both front airbags deployed without warning and without any accident or impact. There were no warning lights beforehand, and no collision occurred. The deployment also caused my windshield to crack. After the airbags went off, the dashboard displayed a ‘SRS airbag system problem’ message. This is a serious safety concern as the vehicle was operating normally at the time. I’m requesting that this be investigated as a potential manufacturer defect

I have contacted Honda Dealer and Customer Service in regards to NHTSA Recall Number 24V-064. Honda is declining to correct the recall due to shortage in supply of parts. Honda is indicating that only vehicle with the airbag sensor light on are being prioritize. This makes me uneasy as I do not know whether or not my vehicle airbag will work properly in case of an incident. There is no waitlist for remedy to be corrected.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Honda Civic Si verdict →
