“The contact owns a 2021 Acura RDX. The contact stated that while operating the vehicle, the front headlights and instrument panel lights started blinking off and on. The vehicle was later towed to the local dealer, who diagnosed the vehicle and determined that the body control module had malfunctioned due to water intrusion from the moon roof seals. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 30,000.”

I reported this specific failure to the authorized dealership on three separate occasions, engaging three distinct service advisors during the active warranty period. …”
