Intake manifold snapped, causing the vehicle not to have any acceleration. Cause unknown. Dealer notified. The consumer states that while driving the vehicle in the parking lot, it started to hesitate w/loss of acceleration. The upper intake manifold went out and caused the anti-freeze to mix w/oil, may have damaged the engine, however the mechanic believes it may be fine.
