2016 Jeep Grand Cherokee Speed Control & Cruise Problems

Twice in recent months the car accelerated on its own while idling. I received no warning or message. Both times the car surged forward a short distance. I applied the brake both times, but it didn’t seem to have much effect. The car seemed to slow on its own. My search of the internet uncovered many instances of sudden unintended acceleration involving the Jeep Cherokee, some resulting in severe injury/property damage, so it is definitely a safety issue. There have been many complaints, over many years, about this same problem, but I could not find mention of a recall notice or service advisory. Apparently there has been no definitive identification of the cause. I would gladly have the car inspected, but suspect that the problem can not be easily reproduced. I have had the vehicle for 5 years and only experienced this problem twice. Of course it only has to happen once to cause serious harm.

28000 MILES +\- DRIVING CAR ON FREEWAY IN HIGH SPEED LANE IN LAS 405 - THE MOST TRAVELED HIGHWAY IN THE US, AND THE CAR SLOWED TO A DEAD STOP. COMPLETE LOSS OF ACCELERATION. ALL ELECTRICAL STILL WORKING, LIGHTS, DASH, RADIO. WOULD TURN OVER BUT WOULD NOT START. HOUR EARLIER CAR WAS IDLING AND IDLED TO A STALL. ALL ELECTRICAL STILL WORKING. POLICE HAD TO COME AND STOP TRAFFIC TO WAIT FOR A FLATBED.

I WAS PULLING OUT ONTO THE HIGHWAY FROM A STOP POSITION, AS I TRIED ACCELERATE THE ENGINE ACTED LIKE I WAS IN NEUTRAL OR PARK! I THOUGHT I HIT THE GEAR SHIFT INTO PARK OR NEUTRAL, BUT I WAS IN DRIVE. IT WENT BACK INTO DRIVE MODE SECOND S LATER. SCARY FEELING WITH TRAFFIC GOING 50 MPH AROUND ME! WELL IT DID IT AGAIN GOING FROM A STOP POSITION TURNING LEFT ONTO A BUSY 3 LANE STREET. NOW I KNOW SOMETHING IS NOT RIGHT!! SO FAR NO RECALL ON MY VIN #, BUT MANY OTHER 2016 JEEP GRAND CHEROKEE HAVE BEEN RECALLED WITH SOMETHING SIMILAR. IT'S VERY SCARY , DANGEROUS, AND HAZARDOUS! *TR
