On 12/21/24 I was driving down the mountain into town when I heard this very loud noise, like someone threw a baseball at my truck. I was startled and shaken up. Glanced in my rear view mirror and saw my rear windshield had exploded. When I was able to pull over to inspect it, the window imploded into the back of my truck. Drove directly to Safelite. Told to go through insurance which I did. Windshield repaired on 12/24, paid for by insurance. Found out in the meantime that Acura had an issue with 2019-2023 RDX exploding rear windshields due to a possible faulty rear defroster. I had just turned on my rear defroster before this happened to me. They issued a TSB to dealerships. I never got a recall. Contacted Acura for insurance reimbursement and wanted to have my electrical system checked at their expense. After several conversations, I was denied. Case was closed last week. Although my vehicle was a 2019, my vin was not included in campaign. I also was not privy to what the exact recall said as my vin was not included. I was told I shouldve brought it to a Honda dealer for inspection and repair. Why would I do that when I didnt know there was an Acura issue? I live in the Adirondacks where it snows every day. Time was of the essence. Now I will not use my rear defroster in fear it may happen again. I also will not use my heated seats as I am afraid there is an electrical issue. I can live without the heated seats but driving without a rear defroster in the North Country is not exactly safe. I had asked for them to broaden their recall as it was obvious the same thing happened to my truck but was denied. I have googled and found there a quite a few people who this has happened to, one woman has it happen twice within three months. I feel this is an extremely dangerous issue that Acura will not take accountability for. I also have not had recall done as the nearest dealer is an hour away. Acura will not allow me have have it done by Honda dealer 20 min away.
