Was driving along and transmission downshifted (?) wouldn't change gears. Tachometer was like a race car. Just went wild. Limped it along to a dealership. They informed us it was probably the transmission. It was determined it was indeed the transmission. They also stated that they had 7 more waiting in the service area waiting for parts to repair. Ours was to be #8. We called the dealer we bought it from, they sent a tow truck and towed it to their service area. Luckily, I wasn't out on the interstate going 70 mph as I would have been in just a few more minutes. Very scary situation as I was in 3 lanes of traffic. It was in town, so traffic wasn't moving fast. I was 2 hours into my vacation. Needless to say, that put a damper on things. Had to rent a vehicle, unpack my vehicle and repack the rental. Oh, and by the was it is a 2024 Terrain with ONLY 2400 miles!
