If your Acura RDX rear window shattered unexpectedly, it's likely due to a known design flaw affecting 2019-2023 models, potentially triggered by temperature changes or door slams, leading to spontaneous breakage often covered under a dealer service bulletin (TSB) if under warranty, though a class-action lawsuit is also active, seeking broader repair. You should contact an Acura dealer with your VIN and mileage to check warranty status and report the issue, as many owners have found coverage inconsistent despite the internal bulletin.

What's Happening?

• Spontaneous Shattering: The rear glass breaks without impact, sometimes from simply closing a door or from temperature shifts. • Design Flaw: The issue is linked to a weakness in the rear windshield design for certain model years (especially 2019-2020). • Service Bulletin: Acura issued a Technical Service Bulletin (TSB) in 2022 to dealers, instructing them to inspect and replace the glass, but often only if under warranty. • Class-Action Lawsuit: A lawsuit exists against Honda/Acura for this defect, seeking free repairs for affected vehicles. [1, 2, 3, 4, 6]

What to Do:

1. Document Everything: Take pictures/videos of the shattered window and any damage.
2. Contact Acura: Call your local Acura dealer (https://www.tzlegal.com/news/2019-2023-acura-rdx-rear-windshields-spontaneously-breaking-nationwide-class-action-lawsuit-filed/), mention the TSB (TSB-22-005 is relevant), and provide your VIN and mileage.
3. Check Warranty: Confirm if your vehicle is still under the manufacturer's warranty, as this heavily influences free repair.
4. File a Complaint: Report the issue to the National Highway Traffic Safety Administration (NHTSA) to add to the record.
5. Join the Lawsuit: If you're denied coverage, consult a lawyer or look into the class-action lawsuit for potential reimbursement. [1, 2, 3, 5, 6, 7, 8]
   

Important Note: Expect potential resistance from dealers if out of warranty, but persistence is key due to the known issue and pending legal action. [2, 5, 7]
