2018 Jeep Cherokee service brakes problems

“while i was driving my vehicle put the parking brake on and then i was unable to get it deactivated at first, after a few seconds i got it and moved forward in traffic. after a few feet the vehicle put the parking brake on and i was unable to move once again. this was in the middle of traffic and i ended up blocking the single lane road. I called a family member who was near by and they came and some how got the parking brake off and drove me and the vehicle home. my safety and everyone one around safety was jeopardized because they had to go into oncoming traffics lane to pass me until i got moving. parking wouldn't engage when we got home and service parking brake light was on.”

“Less than 57,000 miles on vehicle. January 3, 2026. Parking brake engaged and froze. Interrupted driving. Got vehicle home. "Service Brake" came on. Attempted all recommended actions to disengage Parking Brake. Parking Brake continued engagement and the Vehicle cannot be driven.”

“The brakes are locked up and will not disengage one week after coming home from the store in the rain. I was lucky enough to have it parked in my garage when I found out. I had a mobile mechanic look it over and I was told that the electronic brake control module needs to be replaced. The vehicle only has a little over 8,000 miles on it so far. I attached a picture of the part and a screenshot of the email stating what has to be done to repair the problem.”

“Doing some investigation into this vehicle, it revealed that the current design of the rear compartment does not provide adequate protection against water intrusion. There are several points of entry through which water can seep into the electronic components, including the improperly sealed connector to the EPB. Furthermore, similar incidents involving the same make, model, and manufacturing year indicated that this is not an isolated problem. Numerous reports from owners of 2018 Jeep Cherokee have surfaced, describing similar cases of water damage leading to the malfunction of the electronic emergency brake. This suggests that there is a systemic manufacturing defect that needs to be urgently addressed. The implications of these malfunctions are significant. Not only does this defect render the vehicle immobile, but it also poses a serious safety risk to the driver and other road users. In both the March 2023 and June 2024 incidents, the affected vehicles were stranded in traffic, creating a potential hazard and increasing the likelihood of accidents.

“[XXX] noticed parking brake was engaged and (P!) warning light was on, I had not turned parking brake on. I pushed brake pedal and parking brake to disengage. Next day it was on again when I started car. I went to repair shop and they added brake fluid, the warning light stayed on. When home I went to repair shop Wednesday [XXX] but when they checked it hours later the light was off and brake fluid was full so we thought the warning light reset. Next day while driving warning chime sounded and (P!) Warning Light came back on and stayed on. Friday [XXX] took it back to repair shop and they said had to take car to a Jeep dealer. Monday [XXX] made appointment and took car for hand car wash, after the wash the Red BRAKE light was flashing and the mileage was also flashing. Did not drive until my appointment on [XXX] Marino Jeep, in Chicago. Marino Jeep called me stating water leaked into control module and caused corrosion to the brake system. I will have an invoice in a week after parts come in to complete the repair.”

“The trunk has leaks coming in. It happened 1 year ago and it is now happening again. Last year jeep charged me almost 4 thousand dollars to replace the computer system because of a leak coming in and shorting the wires. It took 3 months for them to fix. I now see a similar issue was recalled in a year previous model of my car.”
