While driving at highway speed transmission will downshift. Tach goes to ~4000 rpm at 60 mph. A msg shows on dash for few seconds "front end collision avoided" and no one is in front of Kia. It is stuck in the lower gear until the key is turned OFF. When restarted is OK until the next time. The local dealer in Cape Girardeau, MO is no help. They say it doesn't do it when they test drive it, daah, and to bring it in when it happens.
