While my wife was driving on the highway going about 50mph, the rear window suddenly shattered without any apparent cause, startling her. Fortunately, she didn’t yank on the steering wheel and was able to pull over safely. After conducting some research, I discovered that this is a known issue affecting 2019’2023 Acura RDX models and is currently the subject of a pending class action lawsuit. The window was inspected and will be replaced by our car insurance.
