2015 Jeep Cherokee Speed Control & Cruise Problems

Hello my jeep got a message of service 4 wheel drive so i brought it to the dealership. the looked at it and it turns out to be a failing PTU. Jeep did a recall and extended warranty on it but they are saying they will not cover the cost of the repair because its the wrong code. I have code C14A797 and they are saying they need code P14A797. This doesnt even make sense its the same exact faulty part but different codes??? Codes they the car company creates?

Once I stop my vehicle doesn’t accelerate normally and jerks right after. Also the service shifter light came on and won’t go off.

The contact owned a 2015 Jeep Cherokee. The contact that while driving at various speeds, the accelerator pedal was depressed but the vehicle hesitated to respond. There was no warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the failure was associated with the fuel system. The vehicle was repaired under an unknown recall. However, the failure reoccurred while driving. Additionally, the contact stated that the vehicle failed to start. The message "Repair Parking Brake" was displayed. The vehicle was towed to the dealer where it was diagnosed that the parking brake module, the front driver's side axle, the CV joint, and other unknown repairs needed to be completed. The vehicle was repaired. However, the failures reoccurred and the engine was emitting abnormal rumbling sounds while driving. The vehicle was taken back to the dealer where it was diagnosed that water had leaked through the liftgate, which damaged the parking brake module. The vehicle was not repaired. The contact sold the vehicle. The manufacturer was notified of the failure but provided no assistance. The failure mileage was approximately 103,000.

Pressing on the gas and the car does not move. Randomly stops and I would have to turn it off and back on in order for it to drive.

THE TRANSMISSION LIGHT POPPED ON ONLY AFTER HAVING IT FOR 2 MONTHS.

I WAS AT A VERY BUSY INTERSECTION GETTING READY TO TURN LEFT AND WHEN THE LIGHT TURNED GREEN THE AUTO START CAUTIOUS SYMBOL SHOWED UP ON THE DASH AND THE ALL THE LIGHTS CAME ON RIGHT BEFORE MY CAR COMPLETELY SHUT OFF. I HAD TO PUT ON MY HAZARDS BECAUSE I WAS AFRAID OF GETTING HIT. PUT THE JEEP INTO PARK AND RESTARTED THE VEHICLE. I PULLED OVER INTO A SHOPPING CENTER AND CHECKED TO MAKE SURE I WASN'T LEAKING ANYTHING AND TO GIVE IT TIME TO MAKE SURE IT WOULDN'T SHUT OFF AGAIN. THEN THE NEXT DAY IT WAS SHAKING REALLY BAD IN IDLE AND KEPT THROWING THE SAME AUTO START CAUTION LIGHT ON THE DASH. THEN HAD A CHECK ENGINE LIGHT. WHEN TAKEN TO MECHANIC SPARK PLUGS AND COIL PACK FOR CYLINDER 2 WERE CHANGED BUT PROBLEM PERSISTS.

WHILE DRIVING ON A FREEWAY IN NOVEMBER 2020 I HAD ENGAGED THE CRUISE CONTROL AND SET IT AT THE SPEED LIMIT OF 70 MPH. A SEMI TRUCK CHANGED INTO MY LANE WITHOUT BLINKER WARNING. I SLAMMED ON THE BRAKES BUT THE CRUSE CONTROL WOULD NOT DISENGAGE. I THEN BEGAN PUMPING THE BRAKES AND STILL NO DISENGAGEMENT. AS I APPROACHED THE BACK END OF THE SEMI PRIOR TO HITTING IT, I DROVE OFF THE FREEWAY DOWN THE DESCENDING EMBANKMENT STILL PUMPING THE BRAKES WITHOUT DISENGAGING THE CRUISE CONTROL. AS I BEGAN SLIDING DOWN THE EMBANKMENT I BRAKES DISENGAGE THE CRUISE CONTROL JUST BEFORE A COLLISION WITH THE DIVIDER.

When I go to put the the vehicle in park and reverse it wants to shift really hard, not really a shift but more of a jerk. It doesn’t happen every time but it does 50 percent of the time. There was this one time where i went to go put it in reverse and it wanted to rev more then usual. When it MAINLY shifts hard is when I first turn it on and start moving a couple feet it wants to fall on its face. We haven’t had any incidents in it yet but I wanted to see if I could get anything done before any. Me and my boyfriend travel a lot and when we are in traffic it has fallen on its face. There is a gas cap light that keeps coming on and I have replaced my gas cap 2 times.

THE SERVICE SHIFTER ALERT COMES ON EVERY TIME I START THE CAR ALMOST. IT STARTED PERHAPS A MONTH AGO OR SO. IT WAS INTERMITTENT AT FIRST AND RESTARTING THE VEHICLE WOULD CLEAR IT OFTEN BUT HAS GOTTEN WORSE OVERTIME. IT NOW OCCURS EVERY TIME I START THE VEHICLE. I WORRY THAT IT MAY GO OUT AND THE POLAR IS VERY GENERIC. THAT'S CALLED A COUPLE OF MECHANICS INCLUDING DEALER AND THEY'RE EQUALLY GENERIC ABOUT WHAT IT MAY BE, AND JUST TO GET IT LOOKED AT WILL COST ME $120 AN HOUR. THE ONLY THING THAT WAS THERE WITHIN MY POWER TO TROUBLESHOOT WAS TO MAKE SURE FIRMWARE WAS UP-TO-DATE AND I HAVE DONE THAT BUT THE ALERT IS STILL THERE.

I PURCHASED MAY JEEP CHEROKEE IN DECEMBER 2017. ON THE FIRST HOT DAY OF MAY 2020, I WENT INTO MY CAR, AND NOTICED THE DASHBOARD AREA ALONG WITH THE VENTS, HAD BEGAN TO MELT! IT WAS HOT OUTSIDE, BUT THIS IS NOT THE FIRST TIME THAT MY CAR HAS BEEN SITTING IN THE SUN. WHEN I TOUCHED THE VENT, MY FINGERS WERE COVERED IN THIS BLACK, GOOEY SUBSTANCE. NOT ONLY IS THE INTERIOR OF MY CAR DESTROYED, BUT MY CONCERN IS WHETHER THIS SUBSTANCE IS HAZARDOUS. ARE THERE CHEMICALS IN THE PAINT OR ANY TOXIC ELEMENTS? I HAVE SHOWED THE PHOTOS OF THE PROBLEM TO MANY PEOPLE. AND EVERYONE HAS THE SAME ANSWER, WHICH IS, "I HAVE NEVER SEEN ANYTHING LIKE THIS BEFORE." I CONTACTED THE DEALERSHIP, WHERE I PURCHASED MY JEEP. MY AGENT IS CURRENTLY LOOKING INTO THIS. THE SECOND PROBLEM INVOLVES THE SHIFTER. ALL OF THE LIGHTS ARE LIT UP. I HAVE ALREADY HAD AN INCIDENT WHERE I THOUGHT I WAS IN "PARK" BUT IT TURNED OUT I WAS IN REVERSE. I FOUND MULTIPLE COMPLAINTS AND CONCERNS ABOUT THIS PROBLEM IN MY RESEARCH.*DT*JB*DT*JB*DT*JB*DT*JB

I WAS STOPPED AT A RED LIGHT AND MY SERVICE TRANSMISSION LIGHT CAME ON, WHEN THE LIGHT TURNED GREEN I STEP ON THE GAS AND THERE WAS A DELAY DURING ACCELERATION, I WAS IN THE MIDDLE OF THE ROAD IN TRAFFIC AND COULD NOT MOVE MORE THAN A FEW MILES PER HOUR, SO I PULLED OVER TO THE SIDE OF THE ROAD TO AVOID BEING HIT. I WAITED A WHILE ON THE SIDE OF THE ROAD AND THEN I TRIED DRIVING HOME, IT STARTED VERY SLOW UNTIL I GOT GOING AND THEN IT JERKED AND SHIFTED RANDOMLY. I TOOK IT TO MY MECHANIC AND HE TOLD ME TO TAKE IT TO THE DEALER TO HAVE IT RESET/ UPDATED. I STILL OWE MORE THAN IT'S WORTH SO I CAN'T TRADE IT IN, I WILL BE LOSING MONEY. I FEEL VERY UNSAFE IN MY JEEP NOW.

THE APPROXIMATE FAILURE MILEAGE WAS 70,000.

TL* THE CONTACT OWNS A 2015 JEEP CHEROKEE. WHILE DRIVING APPROXIMATELY 45 MPH WITH THE CRUISE CONTROL ENGAGED, THE CONTACT HAD TO DEPRESS THE BRAKE PEDAL SEVERAL TIMES IN ORDER TO SLOW DOWN AND DISENGAGE THE CRUISE CONTROL. THE CONTACT STATED THAT THE FAILURE OCCURRED AT LEAST TEN TIMES WITHIN A SIX MONTH PERIOD. THE VEHICLE WAS TAKEN TO BOB BAKER JEEP (5555 CAR COUNTRY DR, CARLSBAD, CA 92008), BUT THE FAILURE COULD NOT BE REPLICATED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 40,000.

THE CAR JERKS REAL HARD WHEN SHIFITING PASS SECOND, HAS A PROBLEM WITH ACCELERATING AFTER COMING TO A COMPLETE STOP AND IT SOMETIME JERK ONCE YOU GET PASS 35MILES A HOUR ND SOMETIMES IT WANT LET YOU GO PASS 40MILES A HOUR.

CRUISE CONTROL WILL BE SET AND EITHER BE GOING 5MPH+ FASTER THAN WHAT IT'S SET AT, OR NOT SHUT OFF WHEN TURNED OFF . ALSO, CONSISTENTLY HAVING 'SERVICE SHIFTER' COME ON , AND THE SHIFTER WILL STOP WORKING AND LOCK IN THE GEAR IT'S IN OR LOCK WHEN PUT IN PARK AND NOT SHIFT TO ANOTHER GEAR.

VEHICLE TURNED OFF ON ITS OWN UPON REACHING 40MPH AND COMING TO A COMPLETE STOP. VEHICLE LATER TURNED OFF WHILE ON THE HIGHWAY AT 65 MPH IN TRAFFIC WHILE IN THE MIDDLE LANE. THIS MADE THE VEHICLE ACCELERATOR INOPERABLE AND AT THE SAME TIME MADE THE VEHICLE LOSE SPEED SLOWING DOWN WHILE IN TRAFFIC. VEHICLE WAS NEARLY MISSED BY PASSING VEHICLES AND ALMOST HIT. EMERGENCY LIGHTS CAME ON AS SOON AS THE VEHICLE TURNED OFF. VEHICLE WAS SHIFTED TO NEUTRAL TO ALLOW FOR STEERING WHEEL TO NOT BE SO STIFF. FINALLY I WAS ABLE TO PULL OVER WHILE THE VEHICLE STILL HAD SOME TYPE OF MOMENTUM. I TRIED RESTARTING THE VEHICLE BUT THE DASHBOARD STATED "PLEASE WAIT FOR VEHICLE TO WARM UP TO START.' I HAD TO WAIT ABOUT 20 MINUTES UNTIL THE VEHICLE WAS ABLE TO RESTART THEN ACTING NORMAL. CHECK ENGINE LIGHT CAME ON. UPON REVISING THE FAULT CODE P2172 APPEARED.

SOMETIMES WHEN CRUISE CONTROL IS SET VEHICLE WILL ACCELERATE UP TO 10 MPH FASTER THEN SET SPEED. THIS OCCURS EVEN WHEN DRIVING ON A FLAT LEVEL ROAD NO HILLS.HAS ALSO REVVED RPMS UP TO 5 AND SLOWLY DECELERATES ON OWN.

CPSC: I PURCHASED A PEDAL COMMANDER PRODUCT SEPTEMBER 21, 2018 TO ASSIST MY 2015 JEEP'S ACCELERATION. THE MODULE IS A PASS THROUGH ELECTRONIC DEVICE THAT IS INSTALLED BETWEEN THE ACCELERATOR PEDAL. *DT O THE USER CAN SELECT 4 'MODES' THAT WILL PROVIDE A BETTER RESPONSE WHEN THE GAS PEDAL IS DEPRESSED. *DT THE CONSUMER STATED A PEDAL COMMANDER DEVICE WAS INSTALLED IN THE VEHICLE. THE DEVICE FAILED WHILE DRIVING THE VEHICLE IN ECO/CITY MODE. *JS*JB

DRIVING ON THE HIGHWAY, MY VEHICLE TRANSMISSION UNEXPECTEDLY SHIFTS TO NEUTRAL, AND IT SHOWS ON MY BOARD AS " SERVICE TRANSMISSION". IT CAN NOT SPEED UP SUDDENLY. THEN IT WILL GO BACK TO NORMAL AFTER I PARKED AND DRIVE. IT HAPPENED TWICE ALREADY ON THE HIGHWAY. FEEL VERY DANGEROUS.

I RECEIVED A NOTICE FOR A RECALL ON MY JEEP CHEROKEE 2015 INVOLVING THE CRUISE CONTROL. I SCHEDULED THE SERVICE AT BILL LUKE JEEP IN TWO WEEKS. THE EVENING BEFORE THE APPOINTMENT I RECEIVED A CALL THAT THEY COULD NOT PERFORM THE SERVICE DUE TO HAVING "TOO MANY" CARS AT THE SHOP. I HAVE NOW MADE ANOTHER APPOINTMENT AT ANOTHER DEALERSHIP. THIS HAS NOW DELAYED MY GETTING THIS CORRECTED BY 10 DAYS.
