2012 Jeep Grand Cherokee Brakes Problems

In 2018 the brake booster was tested (vacuum test), and was deemed fine, even though the part itself was placed incorrectly per the recall and could fail at any point. It was not replaced, and marked the recall as closed. Last week the part, brake booster, failed while driving. Jeep is not willing replace due to recall being closed in 2018 and overall recall closed in March 2022.

JEEP WAS HAVING BRAKE PROBLEMS. REPLACED ALL THE BRAKES THIS SPRING AND STILL HAVING A PROBLEM. TOOK THE JEEP IN TO THE DEALER IN JUNE TO HAVE THE BRAKE BOOSTER LOOKED AT, SAID IT WAS FINE. SINCE THEN THE BRAKES HAVE BEEN GETTING WORSE. TODAY I CRASHED INTO THE FRONT OF MY HOUSE. THERE IS SOMETHING WRONG WITH THE BRAKE BOOSTER, LIKE I TOLD JEEP BACK IN JUNE. THIS SAME THING IS HAPPENING ON MANY OTHER JEEPS. PLEASE SOMETHING HAS TO BE DONE. THE DEALERSHIP IS SAYING THEY LOOKED AT THE "SPLASH SHEILD" UNDER THE RECALL AND SINCE NOTHING WAS WRONG THEY ARE NOT RESPONSIBLE FOR ANYTHING ELSE ON THE BOOSTER. PLEASE READ OTHER JEEP OWNERS HAVING THE SAME PROBLEM. HTTPS://JEEPGARAGE.ORG/F73/MORE-BRAKE-BOOSTER-INTRIGUE-186178.HTML#/TOPICS/186178?PAGE=3. I TOOK THE MASTER CYLINDER OFF AND THERE IS A BUNCH OF RUST INSIDE THE BOOSTER. IT'S A CLOSED SYSTEM, DEBRIS SHOULDN'T BE BUILDING UP OR RUST SHOULDN'T BE GETTING IN THERE. MAYBE THIS WAS CAUSED FROM THE SPLASH SHIELD AND WATER GOT INSIDE?

SAFETY RECALL WAS DONE INCORRECTLY, LEADING TO BRAKES FREEZING UP. DEALERSHIP WAS UNABLE TO PROVIDE PAPERWORK SHOWING THAT THE RECALL HAD BEEN DONE ACCURATELY. ACCORDING TO RECALL T59/NHTSA 17V-572 A VACUUM TEST SHOULD HAVE BEEN COMPLETED. IF THE BOOSTER DID NOT PASS TESTING, THE BRAKE BOOSTER SHOULD HAVE BEEN REPLACED. THE BRAKE BOOSTER WAS NOT REPLACED, ALLOWING MOISTURE TO ENTER AND FREEZING UP. IMAGES OF THE CORRECT INSTALLATION SHOULD HAVE BEEN TAKEN IN ORDER TO BE SUBMITTED FOR THE RECALL. THE JEEP WAS IN A SHOPPING PLAZA, MOVING FROM PARKING LOT TO ANOTHER WHEN THE BRAKES FROZE UP. UNABLE TO GET CALL BACK FROM DEALERSHIP SERVICE MANAGER. *DT CONSUMER STATED RUST BUILT UP INSIDE, BECAUSE MOISTURE WAS GETTING IN. *JB *DT*JB

The brake booster of my 2012 Jeep Grand Cherokee that was supposedly inspected and or replaced as part of a recall that I had performed on the vehicle on 12/22/2017 has intermittent failure. Prior to having the recall work performed on the brake booster I had no issues with my power brake systems. However, within a year of having the recall work done I had the BRAKE warning light come on while driving and noticed that my brake pedal was extremely firm when trying to start my vehicle. I made an appointment at a Jeep dealer to have the problem diagnosed and fixed immediately but the problem went away before my scheduled appointment. The problem recurred (BRAKE warning light and extremely firm brake pedal upon starting) about 2 weeks ago. I immediately drove to the nearest dealership and asked that they scan what error code was causing my BRAKE light (suspecting that it was a faulty brake booster but wanting a definitive diagnosis prior to pursuing the matter). Thankfully even though the light had gone off by the time I got it to the dealer they said the error code was still stored and came back as "C0021-02" or "Brake Booster - General Signal Failure" that likely indicates a failing brake booster BUT the dealer also said I was out of warranty and so no work would be covered even though the brake booster recall work led to this dangerous intermittent failure. I have had multiple occasions recently where my vehicle has taken longer to stop than expected and I never know when its going to happen and so I have to leave very long stopping distances now or else risk rear-ending a stopped vehicle if my brakes randomly stop working effectively (also to keep my kids safe from being in an accident when I need to get them to school). I can provide the brake booster for inspection if/when this defective part is replaced properly at the manufacturer or the dealership's expense. The time and specifics below refer to the first time the first time the BRAKE light activated.

WHILE STOPPING AT A DRIVE-THROUGH ON MY WAY TO WORK, THE BRAKE SYSTEM EXPERIENCED AN ISSUE. I WAS AT A STOP WHEN THE BRAKE PEDAL BACKED UP FROM THE FLOOR AND THE JEEP STARTED TO ROLL FORWARD. I HAD TO STAND ON THE PEDAL WITH BOTH FEET TO KEEP THE VEHICLE STOPPED. I WAS ABLE TO PARK FOR A MOMENT IN ORDER TO FIND A WAY TO GET THE VEHICLE SAFELY TO A NEARBY REPAIR SHOP. THEY IDENTIFIED THE ISSUE AS MY BRAKE BOOSTER. THIS PART WAS SUPPOSED TO HAVE BEEN ADDRESSED WITH SAFETY RECALL P14 BACK IN 2014. EITHER THE PART WAS NOT REPLACED, THE REPAIR WAS NOT EFFECTIVE, OR THE REPLACEMENT WAS ALSO DEFECTIVE SO AS TO CAUSE THE SAME FAILURE FOR MY JEEP NOW. ONLY 5 YEARS OLD AND MY SECOND CATASTROPHIC SYSTEM FAILURE IN AS MANY MONTHS. SO GLAD I WAS NOT STILL ON THE HIGHWAY WHEN THIS HAPPENED OR THIS COULD HAVE CAUSED A SERIOUS ACCIDENT!
