That's low miles for belt to go bad. If there's something defective on the pullies it could cause another failure. I would keep a watch on it for a while to be safe.It’s always something they say,,Went to get gas and the serpentine belt broke.Just turned 39000 miles
Called the towing service and it’s on it’s way for repairs
I've had a couple of v belts break but never a serpentine belt.
Worst break down I have had was when an oil filter can apart and pluged the oil passages. Had to replace the engine. The maker of the oil filter paid the expense.
