“Auto lock issue. At 118,000 miles my auto locks started to automatically lock when I tried to unlocked them, essentially trapping me in the vehicle. As soon as I click unlock they immediately relook. If this isn't a safety issue in need of a recall I don't know what is. I've looked into the problem on other forums and it seems quite common. Yikes! Please get this recall done!”
