NHTSA complaint #11768723

Owner complaint summary

My 2023 Acura MDX has developed a windshield washer system failure affecting both the front and rear washers. The system is clogged and is no longer able to spray washer fluid properly. I found a documented case involving 2022-and-newer Acura MDX vehicles showing what appears to be the same failure mode: coating on the washer-fluid reservoir can become gel-like, enter the washer system, and clog the filter, pump, lines, and/or nozzles. Video reference: [XXX] The symptoms shown are essentially the same as those on my vehicle. I also found an American Honda service communication concerning the 2022 Acura MDX that specifically requested dealer feedback on vehicles with an inoperative or weak washer-fluid system and asked whether the washer tank and/or filter was clogged. This raises concern that the problem may be recurring across multiple model years and may be related to the washer-system design or materials rather than normal wear. I am submitting this complaint so NHTSA can evaluate whether this represents a broader safety-related defect affecting Acura MDX vehicles.
