I have a 2003 4runner, just had the following work done...new muffler, replaced lower ball joint, replaced serpentine belt, new CV (axel shaft)....on the way home from the garage my VSC Trac, VSC Off, & ABS Lights On lights came on....have come on several times since, only staying on for between 1 and 5 minutes. I feel the truck driving differently when on....breaking feels 'assisted'. I'm hoping this is something related to the work done? The garage is going to put it on scanner next week to see, but I'm not trusting them to say it's something they did.....any thoughts?
