2024 MAZDA CX-90 PLUG-IN HYBRID Complaints

I was driving on the freeway on the fast lane and the vehicle slowed from 65mph to zero in about 30 seconds and came to a complete stop. It happened so fast I couldn’t change lanes to get to a safe spot. I was left stranded on the fast lane of the freeway with traffic coming right at me. Vehicle displayed a Hybrid system malfunction message.

The driver-side mirror has a lot of vibration when driving on the highway (60+ MPH). This vibration creates a distraction, and reduces visibility of cars/objects in the mirror. The issue has not been brought to attention to the dealer although seems to be a widely occurring issue amongst these cars.

The driver side mirror glass vibrates and shakes inside the mirror housing at high speeds, over 50mph. The vibrating glass makes it hard to see objects behind the vehicle or judge distance on the driver side. The passenger side mirror glass is unaffected, does not vibrate, and I can clearly see objects behind the vehicle on passenger side. Additionally, the mirror housings on both sides of the vehicle seem to be tightly attached to the doors. The vibration is strictly isolated to the glass inside the mirror housing on driver side.
