2013 Jeep Grand Cherokee: adaptive cruise control problems

Filed Mar 10, 2021 · 98,000 miles · TX

My jeep has died on me as I'm traveling on the highway at rates of speed between 60-75 MPH. I have been able to coast to side of road fortunately so far. This has happened numerous times in the last 6 months. It will usually start back up in about 15 mins. A few times it took longer. There is no warning, it just loses power and will not accelerate. This has happened with and without cruise control in use.

Cruise control suddenly does not kick off using controls unless brakes are applied, nor does it engage all of the time. There is no difference in when vehicle is moving or stationary but will sometimes occur after blinker is used. No blind spot detection alert or message at all.

Current issue - while waiting in a fast food line the battery light came on... After receiving food - I pulled into a parking spot and before I could turn the vehicle off, it started giving off error codes related to various electrical items not being available - first warning - svc. Air suspension - second - blind spot detection not available - third evic error - fourth - adaptive cruise not available... Then died and smelt like burning rubber when I exited the vehicle... A failed effort by roadside service to jump the vehicle did manage to turn on the windshield wipers which wouldn't turn off but that's all that accomplished so I had roadside service put it on a flatbed and tow it to my house since nothing was opened and I didn't want to leave it somewhere with the windows down (of course they wouldn't roll up)... Pretty clearly this should be part of the t39 alternator recall that was issued due to bad diodes which cause the alternator to fry the electrical components with very little warning... The car should die and then the replacement of the alternator should rectify the situation... Not - the light comes on - the car immediately dies - and then you need a new PCM or ECM and all new wiring... Issue #2 - the suspension has been a total fiasco accumulating $13,000 in dealer assessments not under warranty - the whole system has gone out within 80,000 miles and even after replacing 2 air struts - 2 upper control arms - the tie rods end links - and the cv axles - and the compressor - it still sounds like a rickety bucket of junk... When driving - always. Issue #3 - the water pump continuously fails. - not sure if when driving but one would suspect that to be the case.

Cruise control malfunctions with multiple issues. When vehicle is in motion on both highways or on city's streets, the cruise control will not engage most of the time. When it does engage, it will randomly turn off, turn itself on, decelerate, accelerate on it's own.

While driving on the highway using the cruise control, the car suddenly accelerated. The gas pedal was pinned to the floorboard. I attempted to disengage the cruise control by pressing down on the brake pedal. It did not disengage the cruise control leaving the car still accelerating in traffic up to and beyond 90 MPH. I attempted to turn off the cruise control with the switch on the steering wheel but it did not disengage the cruise control. I did see a warning light appear on the dashboard but was unfamiliar with it. I later looked it up in my owners manual and it was the "electronic throttle control" etc) light. Realizing there was no way to disengage the cruise control, my only option was to try to slow the car down by pressing as hard as possible on the brake pedal while the engine was attempting to continue to accelerate. This was moderately successful and allowed me to reduce the speed to a manageable speed to lane change to the emergency lane. Once there I used both feet on the brake pedal where I was able to almost stop the car while the engine raced. It was not able to turn the car off because it was still in gear so I threw the car into park and pushed the off button. The car shut off and I was safely stopped alongside the highway. I have since been able to drive the car but have not attempted to use the cruise control. I have scheduled it to be serviced and will hopefully get some sort of data from the car as to the malfunction. ## VIN passed ## jeep grand cherokee 2013 ## *tt *as *js *dt

Not sure of the dates. Rear view mirror electrical recall repaired. Seat on drivers side gets very hot/must turn it off. Cruise control worked randomly for awhile, now doesn't work at all. Still waiting for recall letter to let me know what to do about latest recall on vehicle stopping suddenly without warning causing a crash! It's my only vehicle and am afraid to drive it!
