“The back windshield just shattered when I closed the drivers door. I looked online and it seems like a known issue and Acura is not taking any responsibility for it.”

“At the end of the work day, I approached my car that had been remotely started through the app approximately 5 minutes prior. I put my work bag in the back driver side, closed the door, then heard small items hitting the ground. I went to the back of the car and found the back window on the lift gate shattered. The door wasnât slammed. The lift gate has only ever been operated with the power feature.”

“Got into the RDX, closed the driver door and rear glass shattered. Called Dealership and spoke with salesman and service manager and both said they never heard of this before. Reading online this has happened several times. Acura in Canada has acknowledged that this is a defect and repairs are done under warranty. What can be done in USA?”

If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
