Example complaints

“During a frontal drivers side crash the drivers side airbag did not deploy causing injury to the driver. However the passenger side airbag did deploy, but no passengers were present at the time of the accident. The impact of the crash was mostly drivers side. I also believe the braking system failed since my car failed to slow like a car should during braking.”
