2022 Acura Rdx

We were driving our 2022 Acura RDX on the expressway when the we suddenly heard a very loud pop/explosion. A few moments later we could hear wind above our heads. We realized the sunroof had literally exploded and shattered. Neither me nor my passenger saw any road debris whatsoever and believe this simply happened without any warning or cause.

Vehicle has lost power and gone in to ‘limp mode’ numerous times when accelerating, reducing speed to 25-30 MPH. The engine runs extremely rough during this time and will not rev up. This has caused traffic behind me to slow down immediately to the point I’ve come close to being hit from behind. It has also lost power without warning several times when driving at approximately 45 MPH, reducing speed to 30 MPH instantly, after which the engine check light illuminates, causing traffic behind me to slow down until I have a place to pull off the side of the road. The first incident was 10/20/2022 at 1,828 miles. I brought the vehicle to an Acura dealership to have it checked out and the service department couldn’t find the problem. The last time I had it in for service was 10/04/2023 at 8,379 miles, and again, the service department couldn’t identify the issue and told me to set up an appointment for overnight so they could try and replicate the problem. In all instances, when the vehicle is turned off and restarted, the check engine light goes out and it runs fine.

5 different occasions where the car enabled the emergency braking system for collision when there were no possibility of collision. This has occurred twice on the freeway, where all of a sudden, the vehicle slams down on the break, coming to a screeching halt. No vehicle or other object in front, side or back of vehicle that should cause this. The other instances happened on city roads and similar to the freeway instances. Hard braking for no reason, jolting me and passengers forward and causing vehicles behind me to not understand why we stopped randly and took so long to get going forward again as the emergency system doesn’t have a quick override.

What component or system failed or malfunctioned, and is it available for inspection upon request? My rear windshield shattered on its own. My car was parked at work, which is a secure compound that is monitored 24/7 by security guards and cameras. I filed an incident report with security and they reviewed camera footage and didn't find any suspicious activity. I later discovered the incident is a known issue with a 2019-2022 Acura RDX (see Acura's Service Bulletin 22-014 version 2). The security guards took photos of the damage and I eventually replaced the rear windshield the next morning due to safety concerns and heavy rain. How was your safety or the safety of others put at risk? A rear windshield shattering on its own is dangerous to be around because of the flying glass fragments, especially if it happens while driving. It also impairs visibility to the rear of the vehicle. Has the problem been reproduced or confirmed by a dealer or independent service center? No, it has not been reproduced or confirmed by a dealer or service center. Only my employer's security guards inspected the vehicle and camera footage. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only my employer's security guards inspected the vehicle and camera footage. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there were no warning signs at all. The rear windshield didn't have any cracks or anything. I've only had my car for a few months so there's no wear and tear.
