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 major traffic accident on 2/14/22. I was rear ended in traffic by a car going high speeds. The headrest on the driver seat popped off and ended up in the second row on the floor. Because the headrest came off during the accident my head and neck were not supported and I am still recovering at this time. Although I'm thankful to have survived this is likely a safety issue. I do have a picture and a police report if needed.
