What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

I was in a car accident on 6/30/23. I was side swiped and the front airbag deployed and exploded in my face, knocking me unconscious and leaving me with chemical burns. I had a grade 2 concussion so it's hard to remember a lot. I was taken to the hospital. And drivers and passengers from 3 other vehicles were also taken to area hospitals.

June 2023 CrashInjury

I was involved in a head on collision, all of my safety warning notified me but my airbags NEVER deployed. This is a serious safety hazard especially with many problems being reported with airbag deployment. The adjuster and collision center both stated at the rate of speed from the accident, the airbags should have definitely deployed. My car was deemed a total loss from the damage even without the deployment.
