After I purchased a RV and making the trip home, we went through several stop lights. As we were slowing down to make a stop at light, the vehicle made an abrupt downshift. Seemed like it was in fourth gear and went in to first or second gear. The vehicle jerked and the rpm went to around 6000. I thought my engine was going to blow up!! Scary and felt dangerous! Then it happened again approximately 10 miles down the road. I haven’t experienced this since this date but I haven’t pulled anything since then either. Please make this a recall. It isn’t just the 2014 model. I have V8 5.0 6 speed transmission. Please help.
