Example complaints

“There is an active Taillight (Lid Lights) Safety Recall (25V-259) on 2014-2020 Acura MDXs. When I enter my VIN it claims I am not part of this recall but there is sitting water inside my drivers side tailgate lid light assembly. It's only in the one, therefore I am unsure why my vehicle isn't listed/registered as part of this active recall.”
NHTSA complaint #11736688, filed 2026-05“The rear lighting on the left side of the tailgate was accumulating water. Even though it was part of a recall campaign, the period had expired. I had to replace it at my own expense. This could be a broader issue since similar cases may occur for others.”
NHTSA complaint #11724281, filed 2026-03“On my 2020 MDX the rear tail light is filling with moisture and water causing the tail light to fail. There is already a recall from Acura for 2014-2019 MDX for the same issue. Apparently Acura did not correct the issue for the 2020 models which uses the same part and did not address the issue. Acura needs to include the 2020 MDX as part of this recall as well. This is a safety as if the light fail can cause a serious accident.”
NHTSA complaint #11458546, filed 2022-03“Intermitted Flashing Dash Lights, Headlights, and Car Alarms. Steering wheel moving up and down. Looks like the same issue as Service Bulleting 21-055.”
NHTSA complaint #11707264, filed 2025-12“Left rear inner tail light is inoperative. There is evidence of water intrusion in the lower left corner of the tail light assembly. Called dealer, was told by service manager that the concern was not covered under warranty as the vehicle has just over 51,000 miles. Called Acura Care and was told same. 2014-2019 models of this vehicle were recalled for this issue, but not the 2020 models, although they are the same body style and share same tail light part number. The lights are LED and have no replaceable bulbs; entire assembly must be replaced.”
