Open the full vehicle complaint log (all categories)•Make: Acura •Model: MDX •Year: 2018 •VIN: [XXX] •Mileage: 80,594 (as of March 22, 2025) Complaint Type: Vehicle Component/Recall Reoccurrence Component Affected: Exterior Lighting – Taillights Summary of Problem: I am filing a complaint regarding a recurring safety issue involving my 2018 Acura MDX’s taillight assembly, which was previously the subject of a recall. In 2019, the left taillight was repaired under a manufacturer recall related to water intrusion that caused lighting failure. On March 22, 2025, during a routine visit to Acura of Boston (Bernardi Acura), it was determined that the same taillight assembly had failed again due to signs of water intrusion, causing the light to malfunction. The dealership estimated a cost of $805.82 for the replacement. I contacted Honda and requested goodwill assistance since this issue was previously addressed as a safety recall, but they denied my request due to warranty expiration—even though this is clearly a recurrence of the original defect. This poses a potential safety hazard, as taillight failure can impair visibility and increase the risk of rear-end collisions, especially in low-light conditions. The fact that the exact issue has returned after an official recall fix raises concerns about the long-term effectiveness of the original repair. I am requesting that NHTSA investigate whether this issue is affecting other 2018 Acura MDX vehicles and whether an extended recall or follow-up campaign should be considered.
