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.

She pulled into a patients driveway and stopped she went to put it in park and the car just took off into the house. She (the driver) had to be taken to the er. She had her foot on the brake still when the car took off. I have pictures of how the right front tire was dragged through the dirt while brake was applied. It damaged the home and did over 5000.00 damage to the car. She insists it accelerated unexpectedly.

In december of 2013, I was involved in a fender bender. After this accident the air bag light remained on. In january of 2015 I was bumped from behind with no damage. However, I then decided I should take in my car to see why the light was still on. As it turns out, the airbag module was apparently damaged beyond repair. I believe that this part was defective as the speed of either collision should not have been enough to cause the airbag system to completely shut down.
