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.

system works intermittently--sometimes won't engage--other times suddenly cuts off when engaged
Power train, Vehicle speed control, Aug 30, 2026
I am reporting repeated drivetrain and transmission failures involving my 2018 Jeep Grand Cherokee SRT. The problems began with failure of the driveshaft carrier bearing, which was replaced with a brand-new component by an independent mechanic. The transfer case subsequently required replacement and was replaced with a brand-new unit by a reputable dealership. After these repairs, the original transmission mechanically failed at approximately 99,000 miles. I replaced it with a transmission from a 2021 model that had approximately 45,000 miles. That transmission then failed after only approximately 5,000 miles of use in my vehicle. I am now having another transmission installed, meaning my Jeep is receiving its third transmission. By the completion of these repairs, I will have spent more than $20,000 addressing drivetrain and transmission failures. I am concerned that an underlying drivetrain, transmission, electronic/control, or other vehicle-related condition may be contributing to these repeated failures. Replacing major drivetrain components has not resolved the problem, and I am concerned about the safety and reliability of the vehicle. I am also aware of a similar situation involving my niece’s 2021 Dodge Durango R/T with approximately 60,000 miles. Her vehicle is also on its third transmission, with brand-new replacement transmissions being installed under warranty. I am requesting that NHTSA review these repeated failures and determine whether similar transmission or drivetrain problems have been reported and whether they may indicate a safety-related defect or broader pattern.

I purchased a 2018 Jeep Grand Cherokee on [XXX] unaware that the vehicle was subject to a federal safety recall and stop-sale order. The recall (NHTSA 24V-838 / Manufacturer 94B) was issued on November 7, 2024, for a defect in the ABS control module that may disable the Anti-lock Braking System (ABS), Electronic Stability Control (ESC), and cause unintended vehicle movement even while stationary. A stop-sale order (VIR 2024-11-14) was issued by Stellantis on November 14, 2024, prohibiting the sale or delivery of affected vehicles until repaired. Despite this, the dealership sold me the vehicle while the recall was still open and unrepaired. In the months following my purchase, I began experiencing issues with the Electronic Throttle Control (ETC). On June 15, 2025, I paid $770 out-of-pocket for ETC sensor repairs after a loss of throttle response. The vehicle has not yet been inspected by the manufacturer, but this defect may be linked to the broader electronic issues cited in the recall. No warning lights appeared in advance. I have been driving this vehicle daily without knowing it could malfunction in a way that puts myself and others at risk. I only learned of the recall on June 22, 2025, when I searched the VIN through NHTSA’s database. This has caused emotional distress, financial harm, and a complete loss of trust in the vehicle’s safety. I am seeking appropriate accountability for the illegal sale of this recalled vehicle and want to ensure others are not put in similar danger.

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.

The UConnect display on my vehicle is phantom pressing buttons, going to different screens, turning things on and off as I drive. Yesterday, I was put in a EXTREMELY unsafe situation with my vehicle where the UConnect screen turned off my blind spot detection.

I called UConnect and Jeep and they told me they won’t do anything because I’m not the first owner of the car and that it can’t be replaced but for 1,000 of dollars.
