Got in my vehicle as usual, started the vehicle shortly after I heard cracking thought nothing of it and all of a sudden the rear tailgate window shattered completely.
The contact owns a 2021 Acura RDX. While driving at an undisclosed speed, there was an abnormal gunshot sound coming from the vehicle. The vehicle was driven to the residence. The contact inspected the exterior of the vehicle but found no failure. The contact stated that the following day, while driving at an undisclosed speed, the panoramic roof glass shattered, and glass shards fell inside the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 56,000.
The contact's sister owns a 2021 Acura RDX. The contact stated that the rear glass had shattered while the vehicle was parked in the driveway. The dealer was contacted and advised that the earliest availability to replace the glass was in 3-4 days. The manufacturer was notified of the failure and a case was opened; however, the manufacturer later informed the contact that the model year was not covered under TSB: 22-014 (Rear Windshield Glass Shattering). The failure mileage was approximately 60,000.
I closed my driver door and the back window just shattered. The glass just exploded.
My car was parked in my driveway. After starting it up and closing my driver’s side door, the entire rear windshield spontaneously shattered without warning or any external manipulation/force. There was no way of knowing of whether or not this would happen. I fear that if I had my dogs in the car (or a child) someone could have been seriously hurt. Shards of glass went everywhere - in the trunk, all over the cargo area, and all over my driveway. I am now stuck without a car while I try to get this repair figured out. Acura/Honda needs to place a recall on this ASAP after seeing how common of an issue it is for many RDX (and other models) owners.
Rear window spontaneously shattered
I shut my driver door and my rear window shattered. I’ve called the dealer and they said this happens a lot. Our neighbor across the street also had this happen to them last week. The car was not even on.
Windshield washer pump has failed due to washer nozzles being clogged. Washer pump replaced, but still will not work as the nozzles are clogged. Nozzles are on back order, so therefore unable to clean windshield while driving. No idea when the nozzles will be in stock as this item is on critical back-order.
The rear glass shattered by itself wild parked. This is an ongoing issue. I know of a few people with the same vehicle as me, same year and all and they had to replace the rear glass a few times. Acura needs do a recall on the 2021 RDX. Thanks God it happened wild the vehicle was parked. If this would have happened on the highway it would have definitively cause some damages to other vehicles or even an accident.
Wipers intermittently completely stop working, can last for hours or days. This has happened several times already.

Purchased my 2021 in November of 2020. Two weeks after, i was driving with adaptive cruise on at 65 mph on a freeway. 100 yds ahead i could see a diesel going slower than i, so i looked and saw no one coming at all, so i moved over to the passing lane. I got 5 feet into the lane and the car slammed on its brakes, on its own!!! Thank god no one was behind me or i might have died!! I reported this to Acura within 1 week, and then reported it to DOT the next week. I own one of the first 2021 s made, so i didn’t see a lot of feedback. Now after a year and a half i get on the DOT website and see many complaints like mine. This has happens to me maybe once every 3 weeks. Why has the DOT done nothing about this??!!! Also the DOT says there are no recalls on my car but if you go to the Acura website it says my car is under recall for a driveshaft problem, of which i never received a notice. Why does the DOT exist??
