Service brakes, hydraulic, antilock/traction control/electronic limited slip, control unit/moduleNov 7, 2024
Chrysler (FCA US, LLC) is recalling certain 2018-2019 Jeep Grand Cherokee and Dodge Durango vehicles. A malfunction in the antilock-brake system (ABS) module may incorrectly illuminate the brake lights and disable the ABS and electronic stability control (ESC). In addition, the vehicle operator may be able to start and shift out of Park without the brake pedal being applied.
A vehicle that can be started and shifted out of Park without applying the brake pedal can result in a vehicle rollaway. Disabled ABS and ESC systems can reduce vehicle handling and control in certain driving situations. Brake lights that incorrectly illuminate can fail to properly indicate the driver's intention to following traffic. Any of these scenarios can increase the risk of a crash.
Dealers will replace the integrated pressure transducer and update the ABS module software, as necessary free of charge. Owner notification letters were mailed December 16, 2025. Owners may contact FCA customer service at 1-800-853-1403. FCA's number for this recall is 94B. This recall replaces previous recall number 22V-426. Vehicles previously remedied under 22V-426 will need to have the new remedy completed.

Suspension, Electrical system, Service brakes, Dec 6, 2024
All-wheel drive is no longer working due to messages stating "service anti-lock brake system," "service air suspension immediately," and check engine light. All lights and cautionary messages came on at the exact same moment while coming out of park over a year ago. I have had the vehicle repaired twice, and the dealership says, "It is a wiring issue," but within a month after being repaired each time, the messages and issues begin happening again.
Electrical system, Vehicle speed control, Service brakes, Jul 25, 2024
While driving, all the light on the dashboard come on. When this happens the speedometer is not working the windshield wipers come on. The emergency brake light is on, the car shifts out of gear and the turning signals don't work and the hazard lights won't work. This is all happening at the same time. I'm unable to inform people on the road that I'm in distress because my hazard light won't work I don't know how fast or slow I'm going. I can't inform the people on the road that I want to change lanes. Then after a while all the lights on the dashboard would go out and the check engine light would remain on for maybe two days and than go out. This problem has been going on since January I have paid thousands of dollars attempting to get this problem fixed. My car has been back and forth to the same Chrysler central Ave dealership where I purchased my 2018 jeep grand Cherokee to which I'm still paying for.

All three brake lights stayed illuminated during car operation regardless of brake pedal pressed. I was able to shift and start my car without pressing the brake putting my family and other pedestrians at risk of being run over if the car shifted out of park unexpectedly. Also no warning lights were on at all, so I drove on the road with my brake lights illuminated increasing risk for injury or death in a crash. It turns out the part is a hydraulic control unit. It was reading 120psi when the pedal wasn’t even pressed. This was replaced by an independent shop and fixed the issue. I found out that there was a recall done on 2011-2022 Jeep Grand Cherokees. This recall was “Equipment Safety Recall 21A NHTSA 23E-019”. This recall calls out this exact problem for our exact model and the exact part replaced. My vehicle did not qualify for this recall for some reason which does not make sense because of the following information. The Julian date range for the failed part is 8166-9106. The part pulled out of my vehicle has a Julian date of 8228. I am more than willing to provide photos and any documentation showing this repairs high cost and that it was done. There needs to be another recall with these cars to include mine and many others as this issue could cause death of unsuspecting people around the vehicle. It’s ridiculous that my vehicle did not qualify for this recall when I have an obviously failed part that FCA knows about but refuses to fix or reimburse me for. Please investigate this and enact a recall to fix a problem that was bad enough to be recalled once for another batch of cars. There are other cars out there that could cause death or serious injury.

Driving about 45mph down the road and car in front of me suddenly stops. I immediately hit the brakes and had plenty of space to stop but truck wouldn't stop and brake pedal went all the way down to floor and I rear ended the car in front of me. It wasn't snowing, raining nor was the road wet but it was a cold day. Not sure why it didn't stop looking back on it felt like if there was air bubbles in the brake line which caused a delay in stopping, also remember feeling antilock brakes engaging and automatic emergency stop not braking for me when I was close to other vehicle.

WHILE USING THE ACC FUNCTION AND SETTING FORWARD DISTANCE AT ANY LENGTH THE PROBLEM IS THAT WHEN THE CAR IN FRONT OF YOU SLOWS, STOPS,,OR TURNS MY VEHICLE WILL BRAKE ON ITS OWN. HOWEVER, WHILE BRAKING DURING THE MENTIONED OPERATION THE BIG PROBLEM IS THAT THE BRAKE LIGHTS DO NOT ILLUMINATE. I HAVE HAD SEVERAL CLOSE CALLS WITH SOMEONE NEARLY RUNNING INTO THE BACK OF MY VEHICLE DURING THE USE OF THE ADAPTIVE CRUISE CONTROL (ACC). THIS CAN BE EXTREMELY DANGEROUS IF YOU ARE NOW FULLY AWARE OF THIS PROBLEM. THIS SHOULD HAVE BEEN ADDRESSED DURING THE ACC HAZARDOUS EXAMINATION PHASE. A VERY SIMPLE FIX WOULD BE TO INSTALL AN I/P SWITCH IN THE BRAKE LINE AT THE MASTER CYLINDER SO THAT THE PRESSURE FROM THE ACC APPLYING THE BRAKES SENDS THE PNEUMATIC SIGNAL TO AN ELECTRICAL SIGNAL THAT LIGHTS UP THE BRAKE LIGHTS. THIS PROBLEM SHOULD ABSOLUTELY HAVE BEEN CAUGHT AND ADDRESSED DURING THE DESIGN PHASE. I FOUND OUT WHEN I ASKED A SERVICE MANAGER ABOUT IT AND HE SAID THE LIGHTS DO NOT COME ON. HE ALSO SAID THEY KNOW ABOUT IT.
