Sudden breaking of panoramic glass on sun/moon roof. I believe this is related to the clicking noise that is caused by the improper bolting in this model. There is an active service bulletin for the improper bolting/flexing in the panoramic glass. I called the Acura dealership where this was bought and they didn’t acknowledge that. I had my two children, toddler and infant, in the back. They like the panoramic open. If this broke on top of them this would be a very serious injury.

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.

The panoramic sunroof makes popping sounds when I drive the car up or down ramps or curbs at angles that twists the chassis. This could potentially break and shatter the glass on top of the driver and passengers or worse dislodge from the mounting bracket and fall into the cabin of the car.

The panoramic sunroof exploded on our Acura RDX model 2021. Me, my wife and our 3 month old son were returning from dinner, we took the ramp and about to merge on a highway then we heard a loud and sudden explosive noise which scared all of us. Thank God we had the sunroof blind partially closed over the real infant seat, so the glass shatters left some minor cuts on my left forearm and back (glass pieces got between my back and driving seat). Also, the glass pieces did cut the sunroof blind/rolling cloth screen. We are glad that we made home safe and not sure what is the process of getting the issue fixed by the manufacturer and thorough cleaning up of the glass remains/dust. Please advise.

On NOV 20th 2021 took the vehicle for Oil change, to Acura dealer. The service tech informed me the hood its not opening. The latch or cable its broken. The part its not in stock. I can't open the hood to check all necessary fluids, especially windshield washer fluid. I think its safety concern when I'm out of washer.
