clockspring malfunction causing horn, cruise control, and air bag not functioning

NHTSA complaint #11600247 — an unverified report by a vehicle owner.

VEHICLE SPEED CONTROL

We were about an hour away from home (in the mountains) and our Jeep had been running fine. We had stopped for a while and when we got back to our Jeep and started it, just about every warning light on the dash board came on and wouldn’t go off (the brake light, check engine, airbag, ABS, etc.) The middle of the dash was also flashing different messages…”service park assist and service power steering”. We started to drive and the car was jerking really hard while it was shifting gears. We think it was getting stuck in a high gear because it would hardly drive after we stopped at a stoplights. We turned our hazards on and just tried to make it to an auto parts shop. Our windshield wipers were automatically coming on and the speedometer and RPM needle were both going up and down really quickly. We spent just shy of two long months without our Jeep while it was in the shop. The mechanic ultimately replaced the clock spring and the TPIM. Meanwhile, I joined a Jeep Grand Cherokee Facebook group and it seems like this is a pretty common issue in Jeep Grand Cherokees. It was a costly repair and was very difficult for us to go without our second car for two months. I really feel like this issue needs to be addressed by Jeep.

I was driving and the battery light came on with a chime, within seconds the car smelled hot, the air conditioning went out, road hazard lights on dash indicating flat tire came on, windshield wipers were going on and off at different speeds and windows were opening and closing and then did not work at all. I got the car into the driveway as I was en route to our home. As I got car to the driveway I lost all power. I had the same thing happen in 2019 - Report # 11255268. I do not know where to go to get the vehicle repaired or it the old recall will apply to this problem once again. Should I have the car towed to a dealer? I have my own private mechanic that addressed the problem in 2019. Please contact me asap. I don't know what the plan of action should be. Can I bring it to my own mechanic or does it need to go to a dealer. Please call or send me an e mail as soon as possible as I am without a vehicle. My number is [XXX] or e mail me at [XXX]. OR [XXX]. or use both e mails. Thank you! INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

THIS IS MY THIRD TIME EXPERIENCING THIS SYSTEM FAILURE. EACH TIME WHILE DRIVING AND THE VEHICLE IN MOTION, THE TRUCK SHUTS OFF. EACH TIME THIS HAS ALMOST CAUSED AN ACCIDENT AS I WAS TURNING ONTO A STREET. THE FIRST TIME IT SHUT OFF IN THE MIDDLE OF DRIVING WAS AS I EASY SLOWING DOWN TO STOP AT A RED LIGHT AND LOST ALL CONTROLS AS THE VEHICLE DIED. I DID NOT ACCIDENTALLY TOUCH ANYTHING. THIS IS EXTREMELY DANGEROUS AND SOMETHING NEEDS TO BE DONE BOUT IT ASAP. IT TURNS OFF UNWARRANTED WHILE DRIVING. I HAVE TO PUT THE VEHICLE IN PARK AND PRESS THE START BUTTON TO TURN THE VEHICLE BACK ON. I DO NOT KNOW WHAT PART IS CAUSING THIS PROBLEM. IT HAPPENS OUT OF NOWHERE OCCASIONALLY AND NOT EVERYDAY EITHER.

MY GRAND CHEROKEE HAS STALLED SEVERAL DOZEN TIMES OVER THE PAST FEW YEARS AND THE DEALER CAN'T FIX IT. THE CAR STALLS WHEN SLOWING TO A STOP OR TURNING THROUGH AN INTERSECTION BUT WE CAN'T DUPLICATE THE PROBLEM AT THE SERVICE CENTER. THE DEALER KEPT THE CAR FOR NEARLY A MONTH TRYING TO DUPLICATE THE PROBLEM BUT COULD NOT, BUT I HAVE KEPT RECORDS OVER THE PAST YEAR OF ALL STALLS AND THE CONDITIONS AND THE ONLY CONDITION THAT REMAINS CONSTANT IS THAT I AM QUICKLY BRAKING FROM 40 MPH OR FASTER OR I AM BRAKING WHILE TURNING. INITIALLY IT ONLY OCCURRED WHILE TURNING LEFT, BUT NOW IT OCCURS WHILE TURNING RIGHT AND WHILE BRAKING QUICKLY WHILE GOING STRAIGHT. I HAVE BEEN IN SEVERAL NEAR MISSES DUE TO LOSING POWER STEERING AND BRAKES AND I AM TO THE POINT TO WHERE I CAN'T ALLOW ANYONE BUT ME TO DRIVE THE CAR DUE TO THE SAFETY FACTOR. TWICE I ALMOST HIT A CAR WHILE TURNING AND ONCE A BIG RIG ALMOST HIT ME IN THE SIDE AS THE CAR STALLED MID-INTERSECTION OF A SIX LANE HIGHWAY. THE CAR IS STILL UNDER CHRYSLER'S WARRANTY, AND AS NOTED, THE DEALER HAS TRIED TO FIX THE PROBLEM, BUT HAS FAILED TIME AFTER TIME. THE PROBLEM HAS OCCURRED DOZENS OF TIMES BUT THE LATEST TIME WAS TODAY, AT WHICH POINT I DECIDED TO SUBMIT THIS COMPLAINT. ALTHOUGH I CAN'T DUPLICATE THE PROBLEM ON DEMAND, THERE ARE 3LOCATIONS WHERE IT MOST OFTEN OCCURS, AND IT MOST OFTEN OCCURS IN THE MORNING. THE FIRST LOCATION IS ABOUT 2.5 MILES FROM MY HOUSE, AND THE OTHER TWO ARE 5 MILES EACH FROM MY HOUSE. TWO OF THE THREE LOCATIONS ARE AT INTERSECTIONS WITH RED LIGHTS, WHILE THE THIRD IS SIMPLY THE LOCATION OF WHERE I WORK WHERE IT HAS STALLED MULTIPLE TIMES WHILE JUST TURNING INTO THE DRIVEWAY. IT ALSO HAS STALLED SEVERAL TIMES WHILE COMING HOME OR JUST DRIVING AROUND OR ON VACATION. DEALER HAS REPLACED FUEL PUMP RELAY, WIRING, AND SOME EMISSION CONTROL PARTS.

MY ACC SENSOR WILL NOT CONNECT THEREFORE MY CRUISE CONTROL DOES NOT WORK, LEAVING USELESS BUTTONS ON MY STEERING WHEEL. WE HAVE NO IDEA WHAT IS WRONG WITH THE WHOLE SYSTEM. TOOK IT TO THE DEALERSHIP AND WHILE THEY WERE DOING RECALL WORK, THEY CHECKED IT. SAID I WOULD HAVE TO BUY THE $2,000+ ACC UNIT AND THEN IT WOULD PROBABLY BE $1,000+ LABOR AND THEN HOWEVER MUCH IF THEY HAVE TO REPLACE WIRES OR ANYTHING ELSE. I JUST WANT MY CRUISE TO WORK, I DON'T CARE IF THE DISTANCE PART WORKS. WARRANTY WOULD NOT COVER IT AND I'M SURE I NO LONGER HAVE ANY FACTORY WARRANTY LEFT ON MY VEHICLE.

VEHICLE STALLS WHEN APPLYING BRAKES WHILE DECELERATING. ALL POWER IS LOST AND VERY DIFFICULT TO STEER OR BRAKE. THE VEHICLE WILL RESTART WHEN PUT BACK INTO PARK AFTER DRIFTING TO A STOP. THIS IS A RANDOM PROBLEM THAT OCCURS 1-2 TIMES EVERY COUPLE OF WEEKS ON AVERAGE. THE PROBLEM HAS BEEN REPORTED TO JEEP AND HAS BEEN AT THE DEALER SEVERAL TIMES BUT THEY CANNOT REPRODUCE THE PROBLEM AND THERE ARE NO ENGINE CODES BEING GENERATED. THIS IS A VERY DANGEROUS HAZARD AND I HAVE SIMPLY BEEN LUCKY I HAVE NOT BEEN IN A SERIOUS ACCIDENT YET AS A RESULT.

I WAS DRIVING MY JEEP FROM A STOP SIGN AND IT ALL OF A SUDDEN SLOWED DOWN AND WOULD NOT ACCELERATE. THE ENGINE LIGHT COMES ON AND FORCES ME TO PULL OVER, RESTART IT AND IT RUNS FINE AFTER THAT. WELL, IT'S HAPPENED 3 TIMES AFTER THIS AND I HAVE ARRANGED A 7AM SERVICE FOR IT ON MONDAY. THE BOOK SAYS CHECK THE GAS CAP OR IT MAY BE BAD GAS, BUT I BURNED THE GAS DOWN TO 15 MILES LEFT AND FILLED IT WITH SUPER UNLEADED. NO MATTER WHAT I DO, LIKE SHIFT INTO N, REV THE ENGINE, NOTHING WORKS UNTIL I PULL OVER AND RESTART IT.

PROBLEM DEVELOPED JUST AFTER 10,000 MILES WITH MILD VIBRATION ON ACCELERATION. PROBLEM PERSISTED AND GOT WORSE. I HAD VEHICLE CHECKED BY DEALER AND HEAD MECHANIC AT 15,000 WHEN IN FOR OIL CHANGE. DEFINITELY WAS A PROBLEM, TOOK A DAY TO DIAGNOSE WITH HELP FROM JEEP. /CHRYSLER SAID IT WAS FAILURE OF THE TRANSFER CASE/DRIVETRAIN CONTROL MODULE. IT TOOK FROM JUNE 25 UNTIL AUGUST 19 TO OBTAIN NEW MODULE. DURING THAT TIME VEHICLE VIBRATION WORSENED FURTHER REQUIRING BACKING OFF ON ACCELERATION AND THEN CONTINUING ACCELERATION TO GET UP TO HIGHWAY SPEED. VERY MUCH LIKE RIDING ON A BAD WASHBOARD ROAD PLUS NOISE COMING FROM UNDER FRONT AND THEN ADDITIONAL NOISE FROM REAR. WHEN GOING UP MODERATE INCLINES BACK END BEGAN STRONGLY VIBRATING TO THE POINT WHERE IT FELT BACK END WAS GOING TO START HOPPING PLUS A CLUNK NOISE. BACKING DOWN ACCELERATION AND THEN REACCELERATING WOULD LESSEN PROBLEM BUT STILL MADE VIBRATION. FINAL CAUSE AFTER REPAIR: CAUSE LISTED AS BROKEN PROPELLER SHAFT WITH UNIVERSAL JOINTS, REPLACED TRANSFER CASE TO REAR AXLE; REPLACE REAR PROP SHAFT DUE TO CARRIER BEARING FAILURE CAUSING VIBRATION; REPLACE FINAL DRIVE CONTROL MODULE PER DIAGNOSIS FOR SHUTTERING IN DRIVELINE. VEHICLE HAS 17,578 MILES AT REPAIR COMPLETION. PROBLEM APPEARS FIXED IN THE FIRST 500 MILES I HAVE DRIVEN SINCE REPAIR.
