2017 JEEP GRAND CHEROKEE Service Brakes Problems

My 2017 Jeep Cherokee rolled away three times in one day while in Park with the Electric Parking Brake engaged. My driveway has no flat area and slopes toward a public road, creating a serious hazard for my family and traffic. The rollaways occurred suddenly with no warning lights. I had to park the Jeep sideways in a snowbank for two weeks to prevent further rollaways, creating added risks for my family in winter conditions. The vehicle remains at the dealership. During the first two days of the evaluation, the dealer confirmed brake shoe thickness (4mm), verified the EPB software was current, and found no diagnostic codes. They could not recreate the rollaway or identify a cause. No mechanical or electronic faults were found. FCA communication has been inconsistent. I experienced dropped calls, long holds, contradictory statements, and repeated refusals to provide written documentation of the inspection authorization. FCA said they could not escalate the safety case unless the vehicle was already at the dealership, yet still refused written confirmation of the purpose of the inspection, and I was not willing to bring the vehicle in without documentation. After the evaluation, when I attempted to relay the required findings per the RO instructions, FCA informed me the safety case had already been closed, leaving no record of the defect. FCA said only the rental authorization remained open and they could no longer escalate my case. I then had to re-explain the entire rollaway incident. FCA and the dealer now disagree on whether the RO is open or closed, and FCA has not explained who is responsible for the ongoing loaner or what the next steps are. The defect remains unresolved and the Jeep is unsafe to operate or park at my home.

The contact owns a 2017 Jeep Grand Cherokee. The contact stated that while driving at 45 MPH, the vehicle went into LIMP mode and the vehicle stalled. The vehicle overheated due to the radiator not functioning properly. The check engine and brake warning lights illuminated. The vehicle was able to restart after numerous attempts. The vehicle was taken to an independent mechanic, where unknown parts needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was then taken to a dealer, where it was diagnosed that unknown parts needed to be replaced. There was a burning odor, which was later determined to be caused by mechanics leaving rags in the engine. The vehicle was repaired, but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

On [XXX], I was involved in an accident in Maryland while driving my 2017 Jeep Grand Cherokee. It was raining and despite attempting to slow down, brakes performed poorly, causing my car to skid and collide with the vehicle in front of me. Fortunately, no one else was injured, but I sustained a neck injury, and my car was ended up a total loss. During the accident, I noticed the ABS warning light had activated. This, combined with prior experiences of delayed brake response, raised concerns about the vehicle’s safety. Having derive. For over 15 years without incidents, this was my first major accident and I suspect it may be linked to a mechanical issue. After learning about recent calls related ABS/brake issues in Jeep vehicles, I felt it was important to report my experience. I urge you to re-evaluate the safety of the 2017 Jeep Grand Cherokee’s ABS and braking systems to prevent similar incidents in the future.

The contact owned a 2017 Jeep Grand Cherokee. The contact stated that the brake pedal was depressed while in the park position gear, the engine revved and the vehicle accelerated independently forward causing the contact to hit her head on the headrest. The contact confirmed by looking down if in fact her foot was on the brake pedal and it was during the incident. As a result, the contact crashed into the waiting room of a building. The contact remained depressing the brake pedal and shifted into reverse however her head hit the headrest again. The contact then attempted to shift into the park position but the vehicle continued to accelerate on its own and crashed into a parked Mercedes-Benz and then crashed into the rear door of a parked vehicle where the vehicle came to a stop. During the incident, the Anti-Braking System did not engage. The air bags did not deploy. The driver sustained a concussion and neck injury which later required medical treatment. The vehicle was destroyed and towed away. A police report was filed. The cause of the failure was not determined. The local dealer was notified of the crash but no assistance was offered. The manufacturer was not notified of the failure. The failure mileage was 67,500.

The component is known to fail on jeep forums weather it fails completely or was not installed properly and may loose its functionality. The event is when towing a trailer and reversing the car will see the trailer as an obstruction and will engage the brakes. The car is alleged to have an automatic system that when towing is supposed to turn the parking assist sensors off to prevent the event occuring. If that system isn't present there is a button that should allow you to turn the parking system off which it does for about two seconds and start backing up the trailer, then it will automatically turn back on and see the trailer and lock the brakes up which is jarring and startling to say the least. I am fairly certain this could cause an accident if it hasn't already.

Bought my Jeep used in Sept 2023. For the first time hooked it up to my small trailer to pick something up. Pulled around and went to reverse and the rear park assist braking jammed on. At first I wasn't concerned. I knew there was a way to turn them off based on my jeep manual. Unfortunately, the park assist would not turn off. Neither the park assist button on dash nor the settings in the computer screen would turn them off. The light on the dash button would turn on for 2 seconds but then turn right back off. In the computer settings , I would click the rear park assist to uncheck it. It would uncheck for a few seconds then check mark would come right back again. I tried to turn off the front park assist in the computer just to see what would happen. I can't turn those off either. This is extremely dangerous. I was very lucky I discovered this before I left my property. What if I was in a busy place, road, parking lot, etc. So I do have an appt with my dealer tomorrow, who claims to have never heard of this issue before. . But after doing simple google searches on the internet, I found numerous instances of many Mopar vehicles, like my Jeep GC, Dodge Durango, Chrysler Pacifica, etc. who have had the same exact issue when they try to tow something and cannot turn off the Park Assist feature to back up with a trailer attached. I also called the FCA US Customer Service line to tell them about this and they said they had never heard of this problem. Yet in the many forums I found where people have posted about this issue, they have had to get software update done on the Park assist module to fix this issue. So it is known, but FCA is not admitting to it being an issue. This should be a recall, or if nothing else, considered a necessary upgrade. Also found you have a report in your system already on this issue and I found a Jeep service bulletin related to this issue as well. I will see what the dealer says tomorrow.

Car has always run great till last week, turned off Jeep then tried to start-brake is hard, steering is locked, push button lights up acc and run but wont start, fob is good battery, car batteries are new, service tech at dealer cant figure out Im without a vehicle now for a week so far????

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)

I was on the highway and the vehicle shut off. On another incident I was driving the vehicle and the power steering wen out on the vehicle. On another incident after the power steering went out the vehicle put a notice on the dash to put the vehicle in park when the vehicle was already in park. I tried to turn the vehicle off and it would not allow me to do so. Then after repaired multiple times the battery started to over charge to 21 voltage. At this point, the vehicle is just not safe to drive.

Hello, I was driving my 2018 jeep grand Cherokee about 2 months ago when out of no where the car turned off as I came to a hill , the radio volume increased all the way and I couldn't control it , the main break locked, the wheel locked and my shifter lock, I started to roll back down the hill and I had to use my e-break. the car acted like it was turned off but it just died , the radio never turned back down until the tow company did something. i took it to jeep and they were super unhelpful , they said it was a starter , so i paid 2000 to replace the starter to no avail. Now the AC/Heat goes on by itself or just doesn't work, the radio will go all the way up and i cant control it. however jeep in Englewood Colorado said there is nothing wrong with the car.. I think there is a safety issue with the start stop /eco mode. I think once the car turns off to save gas its not turning back on and there is no safe system. i have contracted jeep multiple times to no avail, the car has died on the highway 3 times now once while i was traveling 65 mph . I have paid for 6000 worth of fixes and its still happening.

I WAS STOOPED AT A RED LIGHT ON A HILL WHEN THE LIGHT TURNED GREEN ALL LIGHTS IN CAR TURNED ON THE BRAKES WENT OUT AND THE STEERING WHEEL LOCKED. I WAS ON A HILL AND ALMOST CRASHED INTO A WALL. I HAD NO CONTROL OVER THE CAR. DON'T KNOW HOW THIS HAPPENED. I WAS ABLE TO MANGE AND PULL TO THE SIDE OF THE CURVE. I TURNED THE CAR ON AND OFF A FEW TIMES AND THE CAR WENT BACK TO NORMAL. I WAS VERY LUCKY I DIDN'T CRASH INTO THE WALL OR ANOTHER CAR. THIS WAS AT A BUSY INTERSECTION AND I COULD HAVE KIILED MYSELF OR AND SOMEONE ELSE. I HAVE NOT DRIVEN THE CAR SINCE ONLY MY HUSBAND BECAUSE IM VERY SCARED. TODAY THE MALFUNCTION LIGHT COME ON AND WE DON'T KNOW IF THIS IS RELATED. WE CALLED CHRYSLER AND EXPLAINED THE SITUATION BUT THEY CAN ONLY SCHEDULE AN APPOINTMENT TO SEE THE CAR ON 5/17/2021 . THIS IS A VERY SERIOUS ISSUE AND IM SURPRISED THEY WONT SEE THE CAR RIGHT AWAY. AND TOLD US TO WAIT ANOTHER 5 DAYS. I DON'T TRUST THIS CAR UNTIL IT GETS CHECKED .

VEHICLE WAS TURNED ON AND STATIONARY AT MY PRIVATE RESIDENCE, PLACED IN PARK (NO PARKING BREAK) FOR ME TO HOOK UP A CHAIN TO TOW A COMPACT TRACTOR (WITHIN THE TOWING SPECIFICATION OF THE VEHICLE).

AFTER A FEW MINUTES WHEN THE CAR IS PARKED AND STATIONARY ON AN INCLINE IN OUR DRIVEWAY, IT WILL ROLL ABOUT 3-4 FEET AND THEN STOP ON ITS OWN, ALL WHILE VEHICLE IS IN PARK. THIS DOES NOT HAPPEN EVERY TIME IT IS PARKED ON AN INCLINE, SEEMS TO HAPPEN RANDOMLY.

MY WIFE, (XXXXX), WAS DRIVING THIS VEHICLE. SHE WAS IN A DRIVE-THRU, MOVING AT LOW SPEEDS WHEN THE BRAKES STOPPED WORKING. ROBIN WAS ABLE TO ROLL TO A STOP IN THE PARKING LOT. I RESPONDED TO THE SCENE TO INSPECT THE VEHICLE AND OBSERVED THAT THE BRAKE PEDAL ASSEMBLY HAD BECOME DISCONNECTED FROM THE BRAKE BOOSTER PLUNGER ROD, COMPLETELY DISABLING THE BRAKES. UPON FURTHER INSPECTION, IT WAS DETERMINED THAT THERE IS A RETAINER CLIP WHICH HOLDS THE PLUNGER ROD TO THE BRAKE PEDAL. THIS RETAINER CLIP WAS NOT INSTALLED AND WAS NOT FOUND ANYWHERE IN THE AREA TO INDICATE IT HAD FALLEN OFF. THERE HAS NEVER BEEN ANY WORK DONE TO THE VEHICLE AROUND THE BRAKE PEDAL ASSEMBLY. IT IS MY BELIEF THAT THE FACTORY DID NOT INSTALL THE RETAINER CLIP, OR DID NOT INSTALL ONE CORRECTLY. THANKFULLY, THIS HAPPENED IN A PARKING LOT AND NO LIVES WERE LOST OR HURT.

THE VEHICLE WOULD NOT BACK UP WITH MY BOAT ATTACHED, HAS A REAR STOP FEATURE THAT WAS ENGAGING, WENT TO MY SYSTEM SETUP SCREEN TO DEFEAT THE FEATURE, IT WOULD NOT LET ME, I WOULD REMOVE THE CHECK AND IT WOULD COME RIGHT BACK ON. THE DEALER KNEW THERE WAS A REFLASH FOR THIS CONDITION, BUT IT WAS A YELLOW ARROW, SO THEY WERE NOT ALLOWED TO FIX IT UNLESS I COMPLAINED ABOUT THAT PARTICULAR SYSTEM, HE SAID FCA HAD RECENTLY SAID NO MORE REFLASHS THAT WERE NOT A RED BOLT UNLESS CUSTOMER COMPLAINED ABOUT A COMPONENT ISSUE THE REFLASH COULD FIX. THIS DEALER TOM WHITESIDE (740-869-2296) SAID THERE WERE MORE REFLASHS, BUT COULD NOT DO. SAID THEY ENCOURAGE THEM TO DO ALL IN THE PAST, EVEN PROMOTED IT AS A WAY TO SELL HIM A HAND HELD COMPUTER. DO I SUE CHRYSLER OR THE DEALER WHEN THEY BOTH KNOW AND WON'T BE PRE-EMPTIVE? I WOULD NOT KNOW THIS DIDN'T WORK TILL I NEEDED IT TO WORK.

18 DAYS AFTER PURCHASING MY GRAND CHEROKEE THE CAR SUDDENLY FELT LIKE IT WAS DRAGGING SOMETHING AND HAVING A DIFFICULT TIME MOVING. IT FELT LIKE THE EMERGENCY BRAKE WAS ON, BUT THE WAS NOT LIGHT INDICATOR. WHEN WE PULLED OVER THE WHEELS WERE RED HOT AND WHEN WE DROPPED WATER ON IT TO SEE HOW HOT IT WAS THE WATER SIZZLED. WE ENGAGED AND THEN DISENGAGED THE PARKING BRAKE JUST TO MAKE SURE IT WASN'T ON FOR SOME REASON. WE HAD THE CAR PUT ON A FLATBED AND TAKEN TO THE DEALERSHIP. A WEEK LATER THEY SAID IT WAS FIXED, WE PICKED IT UP DROVE IT THE 23 MILES HOME AND PARKED IT. THE NEXT MORNING ON THE WAY TO WORK IT DID THE SAME THING. A FLATBED CAME AND TOOK IT TO THE DEALERSHIP AGAIN. THE DEALERSHIP DROVE IT AND THEY EXPERIENCED THE SAME PROBLEM AND HAD TO HAVE A FLATBED COME PICK IT UP. WE WERE TOLD THAT THE BRAKES WERE ENGAGING WITHOUT WARNING AND IT WOULD BE FIXED. THE REPLACED EVERYTHING IN THE REAR BRAKES AND WE WAITED A MONTH FOR A MODULE TO BE INSTALLED. THE DEALERSHIP CALLED AND SAID IT WAS FIXED. AGAIN, WE PICKED UP THE CAR, DROVE THE 23 MILES HOME AND PARKED THE CAR FOR THE EVENING. THE NEXT MORNING ON THE WAY TO WORK THE BRAKES ENGAGED AGAIN AND WE HAD TO HAVE THE CAR PUT ON A FLATBED ONCE AGAIN. EVERY TIME THIS HAPPENED IT WAS ON A DIFFERENT TYPE OF ROAD, GOING DIFFERENT SPEEDS AND FOR NO PARTICULAR REASON. THERE WASN'T ANY HARD BRAKING HAPPENING TO MAKE THE BRAKES ENGAGE. IT WAS IN THE MIDDLE OF DRIVING THIS WOULD HAPPEN. IN THE 9 WEEKS OF OWNERSHIP, WE HAVE ONLY HAD POSSESSION OF THE CAR FOR 20 DAYS!!! WE ARE BEING TOLD THE CAR IS FIXED AND WE CAN COME GET THE VEHICLE. I NO LONGER FEEL SAFE IN THIS VEHICLE AND DO NOT WANT IT BACK. I'M LOOKING TO HAVE THE CAR TAKEN BACK UNDER THE RIGHTS OF THE LEMON LAW AND WILL BE INVOLVING A THIRD PARTY TO HELP MAKE THIS HAPPEN.
