Hi all. Posting for my son who recently bought an 02 WRX. Has had no issues until today while driving to work. Said it suddenly lost power steering and brakes, then engine shut down. Would turn over and try to fire but wouldn't go. Called me and I jumped it hoping it just wasn't turning fast enough. We got it to fire but it had a gawd awful knocking noise and seemed like things weren't synced. Had him immediately shut it off and towed it.
My guess - Timing belt. Anyone else want to guess?
