Recalls and investigations
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.

THE VEHICLE BECOMES VERY UNSTABLE (EG, IT WOBBLES ) WHEN I STEP LIGHTLY ON THE BREAK AT SPEEDS OF 60 MPH AND ABOVE. ALSO, THIS VEHICLE HAS A HIGH RISK OF ROLLING OVER ( I LIGHTLY MOVED THE STEERING WHEEL TO AVOID COLLISION WITH A RECKLESS DRIVER THAT ALMOST HITS MY CAR SIDEWAYS ON THE HIGHWAY, AND THE CAR LOST CONTROL NEARLY ROLLING OVER. THE VEHICLE WAS IN MOTIONED ON FLORIDA'S TURNPIKE.

FORWARD COLLISION WARNING DOES NOT WORK. DEALERSHIP SAYS THE SYSTEM WILL WORK CORRECTLY IF THE ADAPTIVE CRUISE CONTROL IS ACTIVATED. ALL INFORMATION IN THE VARIOUS JEEP OWNER'S MANUAL DOES NOT SPECIFIC ACC ACTIVATION AS A REQUIREMENT. SEARCHING THE INTERNET REVEALS MANY PEOPLE EXPERIENCE THE SAME PROBLEM. JEEP DOESN'T SEEM INTERESTED IN HELPING.

MY 2018 JEEP GRAND CHEROKEE TRAILHAWK'S SUNROOF SUDDENLY EXPLODED WHILE DRIVING 60 MPH ON THE FREEWAY DURING A HOT SUMMER DAY. I HEARD AN INITIAL LOUD CRACK SOUND AND MOMENTS LATER THE FRONT SUNROOF GLASS SHATTERED OUTWARD. I WAS ABLE TO GET TO THE SIDE OF THE ROAD BEFORE THE GLASS SHOWERED INTO MY VEHICLE AND OVER MY HEAD. I SHUT THE SUNSCREEN WHICH HELPED, BUT THERE WAS MILLIONS OF GLASS SHARDS AND FRAGMENTS ALL OVER THE INSIDE OF MY CAR AND THROUGHOUT THE CEILING. THIS VEHICLE ONLY HAS ~6500 MILES ON IT AND WAS PURCHASED IN MARCH 2018 BRAND NEW. I HAD THE CAR TOWED ON A FLATBED TRUCK TO THE DEALER THAT I PURCHASED IT FROM AND SINCE, IT'S BEEN IN AND OUT OF THE SHOP 3 TIMES. THE DEALER REPLACED THE FRONT SUNROOF GLASS, SEALS AND VACUUMED OUT MY CAR, HOWEVER THE DAY AFTER PICKING IT UP, MASSIVE AMOUNTS OF GLASS REMAINED IN THE CEILING AREA. THE SECOND ATTEMPT AND CLEANING UP THE GLASS, THEY HAD TO REMOVED THE INTERIOR HEADER AND SEATS TO TRY AND EXTRACT ALL THE BROKEN GLASS FRAGMENTS. I'M TAKING THE CAR BACK IN FOR THE 4TH TIME, BECAUSE THERE IS STILL BROKEN GLASS SHIFTING AROUND BETWEEN THE SUNROOF AND SUNSCREEN. THE REPAIRS HAVE THUS FAR BEEN COVERED BY WARRANTY (MANUFACTURED DEFECT), BUT THIS BRAND NEW VEHICLE IS RUINED. I'LL BE WORKING WITH CHRYSLER CUSTOMER CARE TO SEE WHAT MY OPTIONS ARE AND IF THEY WILL OFFER A NEW REPLACEMENT VEHICLE OR BUY BACK. VERY SCARY AND GRATEFUL NO ONE WAS SERIOUSLY HURT... I'M VERY DISAPPOINTED AND FRUSTRATED TO SAY THE LEAST AND THE SAGA CONTINUES.

BRAND NEW GRAND CHEROKEE, ONLY 400 MILES, TODAY MY BACKUP CAMERA STOPPED WORKING. ON THE DISPLAY I HAVE AN ICON "BACKUP CAMERA" WHEN ATTEMPTING TO CLICK THIS THE BACKUP CAMERA WOULD NOT POP-UP. TURNED THE CAR OFF AND KEPT IT OFF FOR 10 MINUTES, RE-STARTED THE CAR, THE JEEP DISPLAY DOES NOT POP-UP WITH THE SAFETY NOTIFICATION AND THE BACKUP CAMERA DOES NOT COME ON THE SCREEN WHEN THE CAR IS PLACED IN REVERSE. IT WAS WORKING FINE THE LAST WEEK AND A HALF AND ALL OF A SUDDEN THIS MORNING IT WILL NOT WORK. I CALLED JEEP AND THEY ARE UNSURE WHAT IT IS AND MAY BE A SOFTWARE UPDATE.

SIRIUSXM TRAVEL LINK - IS THE PROBLEM. I WAS ENROLLED BY THE DEALER WITHOUT BEING ASKED. SIRIUSXM TRAVEL LINK POPS UP MESSAGES THAT ARE DISTRACTING TO ME AS A DRIVER. THEY POP UP AND WILL NOT GO AWAY WITHOUT PHYSICALLY TOUCHING THE HIGH-TECH SCREEN. AND THEY SEEM TO HAVE A HABIT OF APPEARING WHEN I AM APPROACHING A TURN WHILE USING THE NAVIGATION FEATURES. HOWEVER, SINCE THEY ACTUALLY INTERFERE WITH MY DRIVING (AND FRUSTRATE ME TOO) THEY ARE A DANGER. TO MAKE MATTERS WORSE, I HAVE CONTACTED SIRIUSXM AND THEY ARE UNWILLING TO TURN TRAVEL LINK OFF. THE DATE BELOW IS TODAYS DATE, BUT IT HAPPENS FREQUENTLY. OFTEN GIVING ME WARNINGS FOR "WEATHER EVENTS" TWO STATES AWAY !!! REGARDING A CRASH ... ALL I CAN SAY IS NOT YET (BUT HAS A HIGHER POTENTIAL).

I WAS DRIVING ON THE HIGHWAY AROUND 5:30AM. CLEAR TRAFFIC AND NO LARGE TRUCK IN FRONT. SPEED AROUND 65 MPH AND MY SUNROOF FAILED BY SHATTERING FOR AN UNKNOWN REASON AND GLASS FELL FROM TOP TO THE FLOOR. HAVE MINOR CUT AND THE GLASS. TRAVELING ON FREEWAY.

I WOULD LIKE JEEP TO HAVE A SETTING ADDED TO THE CAR SETTINGS TO HAVE THE DEFAULT STATUS OF THE THE START STOP ENGINE SET TO OFF SO THAT THE DRIVER HAS THE OPTION TO HAVE IT OFF RATHER THAN PRESSING THE BUTTON EVERY SINGLE TIME. I WAS DRIVING THE YESTERDAY AND ALMOST GOT INTO AN ACCIDENT DUE TO THE LAG BETWEEN THE ENGINE STARTING UP AND ME PRESSING THE ACCELERATOR. IT POSES A DANGER TO THE DRIVE/PASSENGER AND OTHER MOTORISTS. THIS IS A SIMPLE SOFTWARE FIX THAT FIAT/CHRYSLER COULD SEND OUT TO ALL VEHICLES EQUIPT WITH THIS TECHNOLOGY.

I HAVE A FEW OCCURRENCES TO TELL ABOUT. 1. WHEN TAKING IT THROUGH A DRIVE THROUGH CAR WASH IT WAS PROPELLED FORWARD AT AN UNSAFE SPEED. THE VEHICLE WAS IN NEUTRAL BUT STILL WAS SHOT FORWARD AND THE BRAKES HAD TO BE APPLIED QUICKLY. THIS HAPPENED TWICE. 2. AFTER COMING OFF A FREEWAY AND COMING TO THE FIRST STOPLIGHT, WHEN THE SPEEDOMETER HIT 0 THE VEHICLE LURCHED FORWARD. I TURNED THE AUTO STOP OFF AND PROCEED DOWN THE ROAD. WHEN I HIT THE NEXT STOPLIGHT, IT DID THE SAME THING, LURCHED FORWARD HARD, WHEN THE SPEEDOMETER HIT 0. 3. WHILE GETTING UP TO SPEED, 70, ON A FREEWAY, THE VEHICLE SEEMED TO "MISS" GEARS AND IT LURCHED A FEW TIMES. 4. WHEN APPROACHING A TURN, AT SLOW A VERY SLOW SPEED, I TAPPED THE GAS FOR A LITTLE MORE SPEED AND IT PROPELLED ME FORWARD HARD AND I HAD TO HIT THE BRAKES. 5. IN THE FIRST WEEK OF OWNERSHIP AN ALERT POPPED UP ON THE CENTER SCREEN INDICATING THE CONTROL PANEL HAD DETECTED A PROBLEM WITH THE CATALYTIC CONVERTER SYSTEM AND IT WAS A FIRE HAZARD. AFTER TAKING IT TO THE DEALER THEY TOLD ME THEY COULD NOT FIND THIS IN THE COMPUTER MEMORY ANYWHERE AND THERE WAS NOTHING WRONG. AT TIMES I FEEL VERY UNSAFE IN THIS VEHICLE AND THE WHOLE REASON I BOUGHT IT IS TO FEEL SAFE AND SECURE. RIGHT NOW THE VEHICLE HAS LESS THAN 1,000 MILES ON IT.

YOU CANNOT USE BLUETOOTH, THE HEAT OR THE RADIO. I CALLED THE DEALERSHIP WHERE I PURCHASED THE VEHICLE LESS THAN 1 MONTH AGO AND THEY SAID I WAS THE 6TH REPORT TODAY AND THE VEHICLES IN THEIR LOT WERE DOING IT AS WELL. THEY STATED THAT THE UNCONNECT SYSTEM MIGHT HAVE BEEN HACKED.
