Adaptive Cruise Control problem #1

Drove about 1 hour using cruise control part of the time. Don't usually use it, but used it 2 months ago with no problem. After 1. 5 hour visit, drove home. Did not use cruise control, but at last 10 minutes acceleration issue started where car would "rev" even though I was not accelerating. Able to manage it with brake and normal driving. Tried to reset cruise (turn on/off), but car still had episodes of "revving". Did not accelerate to dangerous level and controllable. After car sat in garage for 2 hours, I drove out of neighborhood to empty stretch of road and accelerated to 50 with no problems and no revving of engine. Service check scheduled.

Automatic Emergency Braking problem #2

Abs hecu unit has failed, thus posing a safety risk. All brake lights (abs and warming brake lights), in addition to check engine light are illuminated on dash. Faulty relay recall was taken care of in timely manner (recall 188), but now fires are starting in other vehicles due to failed hecu unit (which dealership and independent mechanic has confirmed that I have). More recalls for earlier Hyundai years need to be included in recall 218 or a new recall implemented to avoid cars catching fire due to failed hecu (my car has not caught fire as of the time of this report).
