2018 Jeep Cherokee Brakes Problems

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.

[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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Braking system engaged while driving at ~40mph. Emergency brake also appeared to engage. Once completely stopped, vehicle brakes were locked up and vehicle had to be hauled for service.

My 2018 jeep Cherokee emergency park and brake got stuck and wouldn’t release and I had to take it back to the dealer ship I got it from . We repaired it 11/20/2023 at classic Chrysler in NC had to wait almost 2 weeks because they had to order a part in . They replaced the parking brake switch/module. And it’s about 2 weeks later And the same issue is happening again .

I see no open recalls on this issue however I did find a class action lawsuit related to this issue. My emergency (Parking) brake engaged and will not disengage. I stopped to get gas yesterday and upon re-entering the vehicle two lights appeared, the service parking brake message appeared on the screen along with the brake light. The car would not move the brakes would not disengage. Several attempts to press the switch to turn off the parking brake failed. I sat for 5 hours at a gas station waiting for AAA to find me a tow truck to get home. They were unable to locate a tow because of the need to dolly the vehicle because of the engaged parking brake. A friend came to assist me and after several thousand tries the parking brake disengaged. He followed me home (5 miles). This morning I attempted to take the car in for service as the warning lights were still on the dash. The parking brake is again on and will not disengage.

Water is leaking from body seems and shorting out parking module. It has happened twice.

The right side emergency brake engauged on its own after stopping had to reset the emergency brake to move again

On two different occasions I was stopped at a red light with my foot firmly on the brake, and the car all of a sudden started moving forward. This caused me to barely be able to stop before hitting another vehicle. My foot was still on the brake even though the car was moving forward.

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. It is evident that this issue has the potential to cause harm and must be addressed without delay. Given the recurring nature of this problem and the severity of its consequences, immediate action is imperative. It is crucial that the manufacturing company identify and implement a solution that effectively prevents intrusion into the rear compartment by implementing alternative waterproofing measures. Additionally, it is essential for the company to take responsibility for the vehicles already affected by this defect. Adequate compensation and rectification measures should be provided to the affected owners. This could include financial reimbursement for as well as a recall and systematic examination of all vehicles manufactured during the same period to identify and resolve any potential issues before they escalate.The implications of these malfunctions pose serious safety risks and demand immediate attention.

The contact owns a 2018 Jeep Cherokee. The contact received notification of NHTSA Campaign Number: 25V011000 (Power Train); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The “Check 4WD” warning light was illuminated, and the Auto START/STOP system failed to restart the vehicle. The contact would disengage the parking brake, place the vehicle in park, and restart the vehicle to continue driving. The failure was intermittent. The contact stated that water was leaking into the cabin from the sunroof, causing a shortage in the electrical system. The vehicle was towed to the dealer, who had repaired the electrical system, including systems with the starter. The dealer confirmed that parts for the repair of NHTSA Campaign Number: 25V011000 (Power Train) were unavailable. The contact was able to start the vehicle; however, the Auto START/STOP system needed to be disengaged to drive the vehicle. Additional repairs were made; however, the contact was unable to confirm what the additional repairs were. Some repairs were performed by another dealer, Jacksonville Chrysler Dodge Jeep Ram Arlington (9600 Atlantic Blvd, Jacksonville, FL 32225). The contact stated that there was a rattling noise coming from the front end, and the vehicle would surge forward and take an extensive amount of time to come to a complete stop. The failures were intermittent. The vehicle was taken to a certified mechanic who repaired the front suspension, ball joints, and steering knuckle on both sides of the vehicle. The mechanic advised the contact to return the vehicle if an oil leak occurred. The contact stated that approximately a month after the repairs were performed, there was liquid on the ground underneath where the engine compartment and the vehicle were taken to a certified mechanic, who had diagnosed the vehicle and determined that the engine filter housing and filter needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 150,000.

On several separate occasions my automatic parking brake engaged without me engaging it. It will engage and will not disengage unless car is restarted. On one occasion I was travelling approximately 20 mph when the brake engage and caused the car to stall. The most recent occasion I was unable to disengage the parking brake and had to have the vehicle towed to the dealer. The dealer believes the issue is related to the EPB Module in the rear left side of the vehicle. Water has been leaking into the trunk and corroded the module and connector. I believe this is related to NHTSA investigation number PE 22-009. A technical service bulletin was issued related to this issue and it appears to be a widespread issue with this make/model.

Brake module system in rear left panel got submerged in water and corroded. Ultimately, leaving us with a locked parking brake that we can't disengage.

While driving down a major highway with speed around 55mph on a busy Friday afternoon, my check engine light came on, which caused my abs light, my traction light, and also my parking brake light to come on. I took the vehicle to the dealer on the 12th, and was told my brakes were fine, I only have 25000 miles on the vehicle at this time. After doing a diagnostic test no code was shown for why the lights are on. I was told to bring the vehicle back so they can perform a full check, which will take perhaps overnight, which is more money for a rental car, because I live over an hour from them, plus a deductible on my warranty. I noticed on reviews for 2018 and 2019 jeep latitudes several owners were having the same problems and I am wondering why there is not a recall on it. Several owners stated their car stopped in traffic, but mine did not. Please let me know if any of my expense will be covered if there is a solution to this issue from other owners' complaints. The vehicle has not been repaired yet. Thank You

The electronic parking brake module failed due to corrosion and moisture in the rear driver side inner wheel well where it is mounted causing my parking brake to become stuck thus making the car undriveable. I had to have the car towed to my nearest repair shop, where it sat for 4 weeks due to part back order from dealer. I have had the module replaced and the computer reprogrammed which worked temporarily until the parking brake was engaged again by driving with the door slightly open and the problem came back. It is currently parked in my own driveway unusable.

while driving at about 50 miles per hour the emergency brake alarms along with several other alarms on dash came on. This happened one time before and car was service and a part replaced to correct the problem. This is less than 1000 miles before this incident.

The parking brake pops on when I'm driving done the road!!! Often times when I start my car and put my car in Reverse or Drive and remove my foot from the brake the parking brake pops on and I start sliding down the road until my car stops!!! The major issue is when I was driving down a HWY at 37MPH no on coming traffic or no traffic behind me thankfully my parking brake engages and I fly into the steering wheel with a seat belt on and thankfully my 5 year old was fully bucked into his car seat and left unharmed!!! Although what if my Jeep does this with other vehicles around??? It's a super big safety and hazard!!! I won't ever purchase another Jeep!!
