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.
My car slid off of the road during a blizzard and hit a tree head on. My front end had smashed in and the car was totaled. The airbags did not deploy and the police who arrived on the scene believed that they should have. I brought my car to a body shop to assess the damages as well as look into the issue of the airbags. He told me that all of the crash sensors had gone off and my seat belt had locked up which led him to believe that my airbags should have definitely deployed.

When returning from a 40 mile trip to naples florida, the vehicle stability system displayed failure warning lights. When I made it back to my condo in cape coral, there was s total system failure locking out the transmission, inability to put the car in neutral, antilock brakes, etc. This could have been a major safety issue had I been on the highway .
