A spokesperson for Honda (UK) said: “In accordance with standard national guidelines in the event of recall activity, Honda will contact all affected customers in the coming weeks. They will be invited to take their vehicle to their local Honda dealership so an inspection can be completed and, if a fault is found, fit a replacement airbag inflator unit.
“The repair will be completed free of charge.
“If a customer is concerned that their vehicle may be affected, we would advise that they contact Honda customer services for further support.
“Also, to be clear, it is possible that there may be some overlap with recall notices around airbags already being carried out.”
