NHTSA Complaint #11624520 — 2016 DODGE GRAND CARAVAN

My family was in the vehicle driving on the hwy in town and suddenly the car revved all the way up to 5000 rpms and would not shift out of first gear. When my husband shifted the car from drive to reverse to park the transmission made a loud clunking noise and hard jerking motion, the check engine light came on. There were no warning signs or lamps. this happened all within 30 seconds of driving down the highway. Since the vehicle would not shift out of first gear our safety was put at risk being we were on a major hwy and unable to gain speed or move out of way of traffic.
