Welcome
First, I have to say that @277km (172k miles) if this is it's first major issue it's done pretty well, especially if it's never had a fluid and filter change before.
If they used a flush machine and solvents instead of just doing a drain and fill, that could be what did it in. Always do a drain and fill only, never a machine flush.
Hopefully when they refilled it they used CVT fluid and not standard ATF as that will ruin it as well.
You can use Amsoil CVT fluid, Valvoline CVT fluid, or Castrol Transmax CVT, yuo don't have to use Mopar CVT fluid.
P0741 has to do with the Torque Converter Clutch Variable Force Solenoid (TCCVFS) which controls the TCC apply and release pressure, and controls the TCC apply and release pressure.
Sometimes a fluid and filter change will fix it, but if not then it will likely need to go in to the shop.
I have a 2013 Jeep Patriot Sport 114,000 miles. Two days ago I took a 2 hour drive to see my brother, about 8 min from his house my RPMs went high and I could not accelerate.... this was very scary going about 75mph on a 4 lane highway. I finally got over to the breakdown lane, just as I came...
