NHTSA's summary

This Preliminary Information communication provides information to the technician of a complaint of a sag or hesitation when accelerating. The concern is present when coasting at low speeds of less than 15 miles per hour and then aggressively applying the throttle, or after making a hard stop followed by an aggressive throttle. This concern may also be present while cruising at highway speeds and then an aggressive increase in throttle. This is considered normal operation of the vehicle the throttle is delayed and opened slowly up to .7 seconds to help minimize driveline lash and clunking or will have approximately .5 seconds of zero torque to allow the transmission to shift to downshift.
