Visibility/wiper

84 reports
“My car was parked and off at a local park, I loaded my [XXX] son in the backseat of the car and then I got into my car. Before even turning car on I heard a loud pop sound and got out to look around and then realized it was the back windshield shattering. Apparently this is a known issue with Acura where the rear windshield will spontaneously shattered for no reason. Safety wise this is a concern since I have a child in the back seat and glass is shattering into the car as well as outside on pavement .”

Electrical system

27 reports1 crash1 fire
“• The Media Oriented Systems Transport (MOST) bus network / FAKRA coaxial service cable connectors failed. This failure directly controls the primary infotainment assembly and the central safety display screen. The vehicle and its active components are currently intact, fully operational (with the defect present), and available for inspection upon request. • The hardware defect causes sudden, unpredictable total blackouts of the central display screen while driving. This completely disables the safety rearview/backup camera and mutes vital audible driver-assist safety alerts. Additionally, the defect causes extremely loud, jarring, and distracting popping and crackling noises through the audio speakers while moving, creating an immediate driver distraction and safety hazard on public roads. • Yes. The vehicle was brought to an authorized Acura dealership service center, where the active symptoms (crackling audio and system instability) were documented. Furthermore, the issue perfectly matches the diagnostic criteria of Acura's official technical service campaign (TSB 23-025). • The vehicle has been inspected at an authorized Acura dealership service department…”

Structure

26 reports
“I am reporting recurring water intrusion into the driver-side passenger compartment of my 2020 Acura RDX following significant rainfall. This has occurred multiple times. The most recent incident occurred on August 28, 2026, following heavy rainfall. Water entered the vehicle and accumulated on the driver-side floor, leaving the interior floor in a puddle. I documented the water intrusion with photographs and video and submitted that documentation to my automobile insurance company as part of a claim. The vehicle was not being driven through standing water; the intrusion occurred after rainfall while the vehicle was parked. The vehicle has previously been inspected by North Park Lincoln of Dominion, where I purchased the vehicle. Despite the prior inspection, the vehicle has continued to experience water intrusion into the driver-side cabin following significant rainfall. The recurring water intrusion raises concern that the panoramic sunroof drainage system may not be adequately draining or preventing water from entering the passenger compartment. Water entering the cabin can reach wiring, electrical connectors, control modules, and other electrical components…”
