2017 Jeep Grand Cherokee: adaptive cruise control problems

Filed Jan 7, 2026 · Engine, Transmission · OR

I used my cruise control on the highway and once I turned it off my Jeep began vibrating a lot. My Jeep now vibrates all of the time when I accelerate. I took it to the shop and had over $2,200 in work done and they are unable to find the specific reason that it is vibrating when I accelerate and stated it likely to due to something with the transfer case. After hours of non stop research I discovered that the issue that I am having is exactly like the Stellantis 01C issue but I am not finding my Jeep under the recall list. I also had an issue where my oil cooler housing unit was cracked and had to be replaced because it is made out of plastic.

Unknown or uncertain about needing a recall. Recently my car has been having trouble with acceleration in the sense that either it will lag or stall out and at times will give acceleration even without me trying to depress the gas harder. It sputters like it either cannot get gas or the fuel system is faulty, it keeps throwing codes and the check engine light dings and flashes. Cruise control sometimes will not come on, theres a burnt smell and rough idles, i have noticed a deep humming sound under my feet while driving, and sometimes when shifting from park to gear it jerks really hard, going down the road it acts like it takes too long to shift. It really is very scary when it does these things, its a daily occurrence. Sometimes it drives just fine then all of a sudden will malfunction. I've only had the car not quite 2 years and they said they repaired the recalls in 2018, after I had scheduled an appointment for July 2025.

This is [XXX] . On September 14, 2023 had a very big crash with our 2017 Jeep Grand Cherokee. My husband and Granddaughter were in the crash. Everyone is okay but the Jeep is totaled. At 7:00am, the Jeep accelerated out of control, my husband was trying applying the breaks, but the accelerator over powered the brake system. The car reached speeds of between 74-83 mph based on the Life 360 app our both my husband and granddaughter have on their phones.This occurred in downtown Lebanon KY during the morning school hours. He was unable to stop or slow down the Jeep. It resulted in him running through 2 red lights and 2 4 way stops. He also had to avoid hitting several cars and pedestrians including children. Finally the jeep skidded to the right of the road and hit a telephone pole, a bridge guard rail where the front passenger side tire was torn off, and went up an embankment and hit a tree. The police at the scene estimated the car hit the tree about approximately 50 MPH. No airbags deployed and of course the car is totaled. Our daughter drives our other 2015 Jeep Grand Cherokee and had the same issue a week before this happened but she was on an open road and was able to use the paddles on the steering wheel to disengage the cruise control and get the car under control. Jeep is saying that there is no recall so we will have to pay for the 2015 to be looked at. Of course we are going to do that immediately. The Dealer has engaged a 3rd party from Bosch to retrieve the data from the cars computer system but that has not happened yet. There were no warning lights on, the vehicle is awaiting Chrysler's inspection. The Insurance company deemed the vehicle a total loss based on the photos we sent them. The Police inspected the car after the accident. We have all the service records for both Jeeps. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on a highway at 60 MPH my vehicle started flashing every possible warning light. Airbags, ABS, slip control, cruise control ... Everything. Most concerning was the 'service shifter' alert; the prnd lights on my shifter panel all started flashing and the car (auto transmission) was stuck in one gear and would not shift. Pulling over and restarting the vehicle would 'fix it' for 10-15 minutes until it all happened again. Engine was making an awful loud noise so I pulled over again. This time after turning it off the vehicle would not start at all. After 30 minutes it started and I was able to drive to a town for the night. The next morning I was able to start it and drive it in 1st gear (where it was stuck) to a jeep dealer. There it sits as I type. I have seen many identical issues reported by jeep owners on internet forums and most worryingly, jeep dealers don't seem to have a clear answer. They're commonly replacing the shifter wiring harness but the problem returns for nearly everyone. This incident stranded me in the middle of the night, in the middle of nowhere, and left me very worried about my safety. Whatever is wrong with the vehicle has cascading errors that affect headlight operation (my high beams would now work), slip control (it became non functional even if I overrode it), wipers (in my case they came on without any rain and I could not turn them off...they could just as easily have not functioned in a downpour creating a safety hazard), and braking (the brake pedal was rock solid and not working properly).

I am the original owner for 10 months. Several times over the last ten months, when stopped and then depressing the gas pedal fully without cruise control or launch control engaged, the throttle continues to accelerate even though my foot is removed fully from the gas pedal. It forces you to put the car in neutral and brake until the throttle becomes "unstuck" and the rpms of the engine come back down. I am mechanically inclined and have checked to see if the floor mat or something around the pedal or pedal mechanism was causing the pedal to be stuck but there are no indications of any mechanical interference. I have read from other owners who have had a similar issue with the high performance trims (srt and trackhawk) of the grand cherokee. Again cruise control and launch control were not activated in any way. I know there was a cruise control recall for throttle sticking but this is not being observed with the cruise control set or on. Is this perhaps a related issue ??

Driver was pulling into a parking spot doing approx 2 miles per hour. All of a sudden the car propelled forward, jumped the cement parking block and hit the building that the parking spot was in front of. Driver was going too slow and had foot over brake the entire time so how did the car just propel forward? 1 month or so after accident received a letter that there was a recall on the cruise control system. Took car into the jeep dealer who said that what the jeep did could totally have been a result of the recall????!!!!!!!

Driving on the interstate in wy, 70-75mph, rolling trrain, cruise control on. All of the sudden the vehicle de-acelerated. The transmission was in automatic when this occured. Both of my hands on the wheel when this happened. Tried to re-acelerate, but the vehicle was very sluggish. The gear was stuck in high gear, which would not change until I pulled over, put the gear in park, and then in drive. No injuries, no damage, but I don't want this to happen again. Could have been a badproblem if I was in heavier traffic. When I got home I recieved the recall notice for udden acceleration with the cruise on.

While driving my 2017 jeep grand cherokee, summit, down the highway at 65mph, the power steering and land sense suddenly became unavailable. The jeep veered to the right hard, nearly hitting the car next to me, and off the road without power steering. 2 warnings immediately displayed "power steering unavailable service required and landsense unavailable service required." this vehicle has 23,395miles on it. Note**** this occurred the day after it was in the dealership for the cruise control safety recall u65 repair. The jeep was towed to the dealership and the tow truck driver experienced no power steering while loading and unloading the jeep. The service tech however; had no problem and did not witness the lack of power steering. There were no repairs done and I was told " it was a computer glitch" I am terrified to drive this vehicle!

While operating the SUV in cruise control, it was necessary to brake and re-accelerate while driving on the interstate. However, upon pushing the pedal to increase speed, it took between 10 to 20 seconds to increase the speed from just 60 MPH to 70 MPH. This happened repeatedly over a period of 30 miles. It was very concerning as I was not able to clear traffic properly. I stopped at a rest stop and tried to do the same acceleration from 0 mpg. This time however, the car 'hung' at 5500 RPM's when I reached 75 MPH. I had to move the gearshift into manual mode and back to and unhang it. I reported this to national rent-a-car upon my return. I want to make sure this is reported. I felt unsafe.
