general problems of the 2014 Toyota Avalon Hybrid

Auto suddenly braked to a stop for no apparent reason. Auto had been repaired for the recall, 15v728000, forward collision avoidance: crash imminent braking. Has occurred twice in the last month. Have since deactivited the pre-collision system. Both occurrences happened while on cruise control, traveling at 55 mph in one case and 60 mph in the other. Both were on straight, level highways with no obvious cause. The 55 mph case was while cruise was set at 60 mph but cruise control was controlling at the lower speed to control the distance from the car ahead of me. The car ahead did not brake or slow down. There was no collision in either case. My diagnosis is that the repair for the above recall did not correct the problem.

Nhtsa recall 15v728 involving pre-collision system. Over 6 months have passed since I received notice of this recall. To date nothing has been done to correct the problem other than telling me to turn off the pre-collision system. Both leaving it on or turning it off lessen the safety of the vehicle.

When applying foot on accelerator venicle delays movement and hesitation enging makes rattling noise hit bumps and potholes even highway joint very roughly ,very poor steering control feels unsafe.
