Automatic Emergency Braking problems of the 2017 Jeep Cherokee

Daughter was driving the car when she approached a stop sign the electronic emergency brake engaged while the vehicle was still moving. This caused the vehicle to stop suddenly. She had to manipulate the electronic switch several times to disengage the brake to get the vehicle to move. Luckily this was in a rural town with little traffic.

Parking brake on the Jeep automatically engaged while driving. Had vehicle towed to dealership where a new parking brake switch was installed and programed and told it was ready to go. Picked it up and it did the same thing again and turned on the auto start stop light. Took it back to the dealership and they said water had gotten into the back area and corroded the parking brake module and the connector. They wanted to charge me $2500 to fix. I took the vehicle home and parked it and started doing research. This is a known problem that could affect 1. 2 million vehicles. My Jeep only has 73,500 miles on it and is regularly serviced. It's driven roughly 4 miles a day. This is a safety issue so why isn't there a recall on it. It is a defect in design not a consumer made issue.

Electronic parking brake engaged and wouldn't release. Possibility of occurrence while driving. Problem has been confirmed by independent service center to have been caused by water leakage into the area where the parking control module is located. Water was found pooling in parking control module which corroded connecters. Vehicle has not been inspected by anyone but the service center. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

My car back in June 2025 left me stranded in the turn lane with traffic backing up after the emergency parking brake turned on without warning. I was not able to drive e my car or to release the brake and move my car. I did a thorough review of all possible reasonable switches that could have caused the malfunction. So I tried to turn off all of the warning systems. Once I did this I couldn't drive faster than 5 to 10 mph. I was able to get to a parking lot about 100 ft away. I called a tow truck, spoke with my mechanic at the local dealership. He suggested what I had already done including removing the battery cables. We did all this to no avail. He got the car then took 3 days to get it to release after opening and closing the door 10 times before starting the car again. He said I need a modulator valve. We have been waiting for over 6 months and my car is still waiting for this part. I can not drive the only car I own when I have a safety issue. Should this had happened while driving with my grandson in the car it is unsafe and it isn't what an autistic child needs to face. This incident has happened 4 times since it happened in June. Every time it takes place, I have to turn off the car open and close the door 10 times before the carvwill release and reset the computer system to make the car drivable again. I did check with the dealership yesterday and still other Jeeps of this year has the same issues but my car is not in that listing. What does a person have do when it is clearly a manufacturer defect?.

Electronic parking brake (epb) module. Yes confirmed by a independent service center. Warning park brake indicator. This is the second time happening. First time was sept 2024 was fixed. Taking it in tomorrow for confirmation, if same issue mechanic stated the part is on national backorder!!!! unable to release out of park brake which in turn, unable to drive car. Safety issue when driving, stops abruptly, can't disengage safety brake.

E-brake service light came on and couldn’t release it, so it had to be towed for a second time in 3 days. The first mechanic released it and said I would be able to drive it until I could get it to the dealership for a possible computer issue that he wouldn’t be able to preform. I drove it a total of 9. 5 miles after this before it did it again and I had to have it towed. This was very scary to know that the e-brake could just lock up at anytime or anywhere. I could easily get injured or killed if it happened at the wrong time or place. The dealer found that the module was full of water and needed to be replaced. This is my 3rd Jeep in almost 31 years and now I’m not feeling safe with a Jeep anymore. Why hasn’t there been a recall when it’s a big safety issue? I did get warning lights when it happened the 1st time and did have it towed because it wouldn’t disengage no matter what I did. It’s costing me $400+ to replace the module and $400+ to put in a new multifunctional switch that the dealers repair shop also states is involved with this issue. Also, it cost me $105 for the 1st tow and $171 for the 2nd and $110 for the 1st mechanic to look at it. Again, I’m a senior citizen and should not feel scared to drive my vehicle nor need to spend $800+ and an additional $386 to resolve an issue that Jeep has known about for years and is just waiting for it to kill someone before they respond!.

The automatic transmission shifter transmits a warning to the instrument panel display with the words service shifter. All of the red shifter console lights light up at once. The vehicle will not engage the park safety brake at times after parking the vehicle when the warning is illuminated. While operating the vehicle no other instrument readings are available (speed, mileage, etc). The vehicle has not yet been inspected by a dealer or mechanic and is a continuing problem. This issue first appeared one month ago and there was no other indication of a problem prior to the first occurrence.

W84 powertrain software- July 30 2022 jerry seiner casa grande dealership technicians inspected and reprogram the pcm and tcm software and closed the recall but 2 months later all the lights on my dashboard came on check engine light service shifter park brake etc. I went back to the dealership and the advisor told me to go to the dealership where I bought it from. I ended up going to larry miller Chrysler Jeep avondale in arizona. The vehicle was braking on its own while driving high speeds on the highway and while driving I almost crashed. My vehicle was in and out of the dealership many times and the technicians didnt seem to know what was wrong with the vehicle. Almost 6 months after the initial problem it seems its fixed. 01/13/2023 was the last time I had to return because the dashboard lights were turning on after driving the vehicle an estimate of 100 miles.

Abs and parking brake keeps initiating while driving my vehicle. Concerned about an accident. I have already had the shifter sensor replaced and still doing the same thing.

The electronic emergency brake engaged on its own. The car would not move and there was nothing I could do to get it out of park.

I went into a ditch hit two trees and a culvert before stopping and no airbags were deployed my 2017 Jeep is a total loss lucky I didn’t receive any major injuries , a laceration to my face quick need to be closed and brusing and scrapes. Mentally I am not okay know it could have been with my children in the vehicle but that day it was just myself.

In August 2021 my got a service parking brake warning. Took to dealership to make a appointment got more warning on the drive there for traction control,brake warning and check engine. Got a appointment for later in week. Asked was it ok to drive was told yes it was ok. Got in car to leave and every 4 to 6 inches parking brake would lock up. Tried a few times to move car but couldn't go any where keep locking brakes up. Went inside told service advisor said I would have to leave it with them. Called for a ride and while waiting for ride service advisor tried to move car and same thing happened to him. They replaced parking brake module. Then in January 2022 left work and got service parking brake warning again then traction control also after a few miles. Managed to make it home and called dealership and got a appointment for a few days later. When I tried to go to work next time car would not start battery was dead. Had it towed to dealership and the brake module and terminal was corroded and green also battery was shorted out and would not hold a charge { fried the battery}. Had to replace battery,control module and wiring harness this time. Guess I was lucky it didn't catch fire this time or it happen while driving at highway speeds.

The Jeep is used as a flat tow vehicle with our 2004 monaco RV. On June 8, we left ducket mill campground in dawsonville GA to return home to cincinnati OH. The vehicle was attached to the RV with the blue ox flat tow system. The four tires on the Jeep were checked and were all rolling. We followed the instructions in the manual, which were also the instructions given to us by the RV dealer who did the installation. One hour and a half after we left, the Jeep started smoking. A truck driver who passed our vehicle pulled off the side of the road yelled that the parking brake was on and needed to be turned off. Upon checking, there were two flat, chewed up tires. We were towed to a tire dealer in ellijay GA to have repaired. We have one of the tires. That night, we found a Jeep salesman from 2017 on youtube explaining the parking brake had to be disengaged to make sure there were no problems in flat towing. This was the first we had heard of this problem. We checked in the manual, and the only mention was that the electronic parking brake can be disengaged. No other warning. When we got home, we had the Jeep into the dealer. They could find nothing wrong with the parking brake system. They drove the car, but dd not flat tow it. The person at the tire store showed us how the tire was worn and torn up in a small area, probably caused by the parking brake engaging. Since we were not in the car and the car worked fine for an hour and 1/2 (not to mention the entire way down from cincinnati to dawsonville), we believe the parking brake engaged by itself as we drove through the mountains.

Several months ago the service shifter warning light began coming on randomly when starting the car and stayed on until the car was turned off. Then the engine light, park assist unavailable and service emergency brake warning lights came on randomly while driving. The dealership installed a new battery but service shifter warning light still comes on randomly when starting the car and stays on until the car is turned off. Took it back to the dealership who then replaced the wheel speed sensor. Service shifter light continues to come on randomly when turning on the car and stays on until the car is turned off.
