2013 TC. After being parked for 4-5 days, I started vehicle, put it in drive, foot off the brake and it didn’t move. The emergency was not on. while parked. Give it a little gas, still didnt move? Gave it more gas and a quite loud bang or clunk happened and the van lurched forward. I wondered if the brakes or just rear brakes had locked on somehow? This is the second time. It does not happen if parked less than 1-2 days. Anyone have any ideas. We just bought thing with 147K km on it and have used it maybe once a week since March15.
