My vehicle dashboard gave me a "service park brake" message. The emergency brake would automatically engage if attempting to shift the car into park. The emergency brake could not be disengaged. The vehicle was towed to a Jeep dealership. The dealership has determined that the "park brake module connector" and surrounding wires have corroded due to water intrusion. They told me the car is considered unsafe as if it were to be driven the e-brake could engage at any moment. They also determined there is water leaking into that area of the car i.e. the rear left cargo area where the brake module sits. My online research has determined this is a common issue, and Jeep has not had a recall or notices about it. The water leaking could come from the sun/moon roof or the wheel well. Please visit this link and others like it to see that many people are having this issue with no long-term solution per the manufacturer. Some people have reported multiple failures of the park brake module on the same vehicle with the repair costing $1k+ each time. https://www.jeepcherokeeclub.com/threads/water-leak-in-your-trunk-check-this-fix-out.245382/

While driving on a low-speed, local road, the Electronic Parking Brake came on which forced me to quickly pull over. The car then displayed a "Service Parking Brake" warning. I brought the car to my local garage and they found that the Parking Control Module and Connector were damaged by corrosion. They needed to replace the module and connector. This could have been a serious safety issue.

I honestly have no idea what system failed but I was doing 80 on the interstate and my car shifted into nuetral. All of the lights came on parking brake, brake and then my car would not drive any longer, luckily I was able to coast onto the shoulder but I literally could have been killed. I had just passed road construction that went from 4 lanes to 2 barracaded lanes. i waited 30 minutes and my car restarted like nothing. So I thought maybe it was a glitch until I was driving again and it did it again. I had to keep putting my car in park and then shifting it back to drive. It has not been inspected yet as i'm trying to get it to the dealership without it cutting off.

An unwanted activation of the emergency brake. When the car is parked or turned off and after turning on the vehicle - the service park brake turns on. After some time, the vehicle stalled and had to be towed to the dealership. Issues appear to be linked to a water leak within the vehicle-??s engine block short-circuiting the electronic brake module. The leak damages the electronic brake module, and when the driver attempts to start the vehicle or shift into drive, it permanently shorts out. The vehicle is unable to move.

Service transmission light came on while driving. I had a warranty on the vehicle so I took it in to dealership in DeQueen AR they fixed the valve body on the transmission and almost exactly 1 year later the service transmission light came on again. Following that my service parking brake light came on and now the emergency brake is engaged and will not disengage. Why has there not been a recall on these items?

I received a warning to service my park brake. At that time it immediately started setting my park brake and I was unable to release it. After much fooling around with it I got it to release and took it to the dealership. They said the park brake module was wet and corroded and suggested I left my windows down. Well I never open my windows. They said the part was not available and probably wouldn-??t be for months. The blew out and cleaned the module. I had no problems for a year and a half (I also never set my park brake for fear it wouldn-??t release) but it started setting itself again so I called the dealership and was again told they didn-??t have the part and couldn-??t tell me when they would. I have also had so many other issues with this vehicle. One being a transmission issue that happened before a recall for it so I fixed the problem and paid for it. When the recall came out I was only reimbursed for half of what I paid. I-??m literally afraid to drive my car for fear of something goring horribly wrong while driving it.

The Emergency Parking Brake engages on its own, and the car can not move forward. The car engine fails and stalls, the vehicle can not be shifted, and I have a loss of steering control. Dash reads error of parking brake needs service, power steering is out, and check engine light comes on. The car won't restart for approximately 1 hour and then turns over and starts. This problem happens intermittently with no warning. It has happened both when parked and moving. I have had the vehicle in at a Jeep dealership but they were unable to diagnosis. It appears to be part of the same case number

While coming to stop at a red light, service parking brake message along with audible ding appeared on the message center. The light on the parking break switch was flashing. Brake light was illuminated along with parking brake light. I arrived at my destination shortly after and attempted to engage the parking brake. Nothing happened. I moved up a few spaces in line at a coffee shop and came to a stop. The parking brake engaged and I was unable to move the vehicle. I turned the car off, put my seatbelt on, put the car in drive and slowly moved forward. The parking break disengaged and I was able to get home. At home I followed the procedure to reset the parking brake. The brake reset along with all lights, brake and parking brake light, and was ok until the next day. Vehicle was parked overnight. Next day tried moving car but Parking brake engaged and I was unable to disengage. Service parking brake message illuminated as well as brake and parking brake light. I read online about water entering the control module and attempted to locate and remove it. See attached photo. The module and wiring harness had a small amount of water inside as well as signs of the water having been there a while.

I have repeatedly been driving down the road then the jeep will instantly kick it out of gear while driving completely loses power so I have to pull over so I don-??t get ran over and today. My electronic parking brake went out a second time in under a year because of the corrosion, every time it is kicked my transmission out of gear was a narrow escape from a wreck I reported this before but you don-??t seem to care so I will be buying a cheap video recorder system and the first time I catch it on video. I will be filing a lawsuit against Jeep and your company for not even looking into it which I referred you to

Water ingress into electronic parking brake module caused brake to lock and render vehicle immobile. Also caused battery drain and electrical issues due to shorting out.

The emergency park brake engages by itself when the vehicle starts and it does not want to disengage. The system is engaging on it's own.

I parked my vehicle in my driveway without turning on the e-parking brake (it is in manual mode). In the morning when I got into the vehicle and put the car into reverse the e-park brake engaged and would not disengage. This was followed by a -??service parking brake-?? message on the dash. I had to have the car towed to a mechanic who found water in the EPB module which was causing the issue. The water seemed to be coming in from some seams in the roof and running directly onto the module. The replacement of the module was very expensive and the car was inoperable for over 1 week.

As I was driving on an interstate highway, suddenly the brakes on my Jeep locked up and pulled over to the shoulder. The dashboard message was that there was a problem with the Parking Brake. After a few minutes the vehicle would move and I drove home. I called a service station and made an appointment to have it looked at but the brakes were now locked and the vehicle had to be towed. The mechanic said there was a problem with water in Parking Brake Control Module and the design would let in water which caused the problem. He said the module and connector needed replacement. The Jeep was then taken to a dealer who was the only one who could get the parts and make the repairs. The dangerous aspect was the brakes suddenly locking up on the highway.
