The dealership did not inform me of an active Acura safety recall related to the issue and stated that they "do not check Acura recalls." Based on their assessment, I proceeded with repairs at my own expense. I paid approximately $435 for the replacement part purchased from an Acura dealership and about $300 in labor to an independent repair shop. …
