Wheels locking up reduced engine power,stabilitrack light on wont turn iff or on

you should have your vehicle scanned. verify that the throttle sensors are reading correctly. Possible abs codes too.

reduced power is usually from the throttle body/throttle pedal system problem. Since the computer can't tell what is actually bad it reduces power so you shouldn't have an accident but can get it home or to a shop.

for the locking up check that the wheel sensors are all working okay
