Cruise Control problems of the 2017 Jeep Cherokee

While driving on hwy 395 traveling north from spokane, wa, with cruise control set at 60 mph, after cresting a low hill and descending the hill my car's engine began racing the rpm went to 4500 rpm and I couldn't get it to slow down or stop by braking or changing the cruise control. My car got to 80 mph when I finally got the cruise control to disengage by pressing cancel again while braking. This is the second time this has happened. It's very scary. I'm afraid to use the cruise control in my car.

The car's cruise control was engaged while climbing a slight hill on the freeway. The car failed to stop accelerating at 60 mph (set speed limit). The cruise control button nor pressing the brakes would disengage the system. After approximately 10 seconds, the car accelerated to 75 mph and finally disengaged. This was during the night, with moderate rush hour traffic on highway 16 near port orchard, wa. The dealer (west hills Chrysler, bremerton wa) cannot find an error code and refuses to repair the vehicle. I deem the vehicle unsafe to drive while using the cruise control system.

Crusie control does not maintain set speed level. When speed is set, the cruise control will rapidly increase by 10 to 15 mph. The speed set point did not change, but the car increases in speed. It did not return to the set point. The cruise control is able to be disengaged.

When using cruise control, it the rpms will jump from between 1 -2 to 5 very quickly and the speed will increase from 65 mph to 75mph for no reason. This occurs whether I am driving on a straightaway, up a hill, or down hill. This has happened on multiple occasions and is happening more frequently. It occurs randomly and is very scary.

Several times within the past 2 months, including today; when driving more than 25-35 miles there will be a "service shifter" notification and the associated 'ding' noise notification that comes on. This notification blocks any action on the screen between the speedometer and rpm monitor and only successfully goes away when turning the Jeep completely off. This happens while in motion, particularly on highways, and seems to happen more often if I have used or am using cruise control on the trip. It also illuminates all of the lights on the shifter (pnrd +/-). It seems that this could potentially cause a more serious issue with shifting, cause me to become stranded, or become dangerous for myself and other drivers.

I deactivated cruise control and started to accelerate to pass someone on the highway, the car continued to accelerate after I had released the gas pedal and so I pressed the cancel cruise control multiple times and tapped on the gas and then the brake after that my car jerked and it stopped accelerating on its own.

1st, my engine light is on due to a faulty thermostat in the engine. I'm displeased a 2 year old car has such an issue. I've been told it's a common problem or defect. 2nd my cruise control goes rogue at times and speeds up excessively if no intervention happens to stop it.

Using cruise control. Applied brakes car started speeding up instead of slowing down or disengaging cruise control had to put car into neutral to get it to stop.

The cruise control was set on my Cherokee. I was going down a hill and the vehicle accelerated. The cruise was set to 59 mph and the speed got up to 67 mph. The motor revved to about 4000 rpms. I turned off the cruise, stepped on the brake and put the car in neutral. After a couple of seconds the motor stopped revving and returned to normal. I put the car back in drive and it was fine. I was on a state highway in a 55 mph speed zone.

I live in a flatter area of the us. No problems here. However, while traveling in some more hilly states recently I experienced multiple occasions when the cruise control would cause the vehicle to accelerate well beyond the setting. 15-20 mph above setting. Engine rpm would go as high as 5000. The system would not immediately disengage. I had to hit the brakes and the cancel button several times before cruise control would disengage. This occurred while traveling at interstate speeds of 65-70 mph.

The contact owns a 2017 Jeep Cherokee. While driving 65 mph with the cruise control activated, the vehicle independently accelerated and the engine revved. After applying the brakes, the vehicle resumed normal speed. The vehicle was not diagnosed or repaired. The local dealer (stephens Chrysler Jeep Dodge ram 200 north street, bennington, vt, 05201) was contacted and referred the contact to NHTSA. The manufacturer was not notified of the failure. The failure mileage was approximately 9,700.
