I have been calling my local dealership for over a year trying to get my car fixed due to the recall and the dealership keeps saying they do not have the parts and will call when they do.

I was informed of a recall notice for my vehicle in the summer months of 2024 (approximately). I took my vehicle to the Culver City Honda dealership in Los Angeles to address this, however they informed me that the issue was not critical and that they did not have the parts. Hence, the recall notice has still not been addressed. I recently (June 2025) imported this vehicle to Canada and I am unable to proceed with the import procedure because of this outstanding recall notice.

There’s been a safety recall and I took my car like more than a year ago to repairs and then the check the car but told me the piece it’s not ready yet. I have to wait almost a whole year for it and I receive the notification that the piece was ready. When I call to make the appointment the lady told me that I receive the notification but the piece it’s not on the Honda yet and I have to wait. Wait more ? I’m seriously concerned about my car and even though I receive the notification that it’s ready she says they haven’t receive the piece yet ? This is a serious matter and my car and even my family we are driving the car and this is absolutely not ok. I don’t know how much more do I have to wait.

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 →
