2004 Jeep Wrangler Electrical Problems

You experienced smoke and a burning smell coming from behind your steering column while driving, with the steering column getting dangerously hot. You discovered that the fog lights remained on even after turning off the ignition, and when you removed the turn signal switch assembly, you found the electrical connector was overheated, internally shorted, and partially melted. The damaged connector has since cracked and deteriorated, disabling your turn signals and flashers, and you're concerned this electrical fault could cause a fire while your vehicle is parked. Fixing this will require replacing the melted electrical connector and possibly the turn signal switch assembly to restore safe operation of your lighting and signaling systems.

Your transmission shifts hard from gear to gear for the first 5 minutes after starting, and the engine randomly throws oxygen sensor or crankshaft position sensor trouble codes. Even though multiple mechanics have replaced these sensors and the engine computer (PCM) twice, the problem keeps returning after a few days. Your transmission also behaves unpredictably when accelerating from a stop, sometimes shifting into second gear while parked, which has created safety concerns. The fix will likely involve diagnosing why the engine computer isn't properly controlling the transmission, possibly requiring another PCM replacement or deep electrical troubleshooting.

THE VEHICLE HAD BEEN DRIVEN FOR ABOUT 35 MINUTES AT APPROXIMATELY 70MPH ON THE INTERSTATE. THE VEHICLE UNEXPECTEDLY BEGAN TO PRODUCE A THICK WHITE SMOKE. THE VEHICLE WAS IMMEDIATELY PULLED OVER AND PLACED INTO PARK; THE VEHICLE WAS ALREADY ON FIRE UPON EXITING. THE GRASS BENEATH HAD CAUGHT ON FIRE AS WELL. THE HOOD BEGAN TO BLACKEN INDICATING A FIRE IN THE ENGINE COMPARTMENT CLOSE TO THE FIREWALL. THE ENTIRE INCIDENT TOOK PLACE IN ABOUT THIRTY SECONDS; FROM THE TIME IT BEGAN TO SMOKE TO THE TIME IT WAS ON FIRE BEGIN THE ENTIRE INCIDENT. A TRUCK DRIVER WITH A DRY CHEMICAL FIRE EXTINGUISHER PUT THE ENGINE FIRE OUT; AFTER LIFTING THE HOOD TO A BALL OF FIRE. THE ONLY INJURY BEGIN LIGHT BURNS FROM LIFTING THE HOOD. ESSENTIALLY, MY JEEP WRANGLER, WITH NO AFTERMARKET PARTS INSTALLED, BURST INTO FLAMES FOR NO APPARENT REASON. *TR

I DROVE MY JEEP FROM HOME TO WORK ABOUT TWENTY MILES WITHOUT ANY PROBLEMS NO WARNING LIGHTS OR ANY VISIBLE PROBLEMS. I SHUT IT OFF WENT INTO WORK ONLY TO LEARN IT HAD CAUGHT ON FIRE ABOUT THIRTY MINUTES AFTER BEING SHUT OFF ! THE HEATER MOTOR AND GLOVE BOX AREA IS WHERE THE FIRE STARTED. FIRE DEPARTMENT CALLED IT ELECTRICAL? CONTRACTED JEEP (CHRYSLER) ABOUT ANY RECALL OR TSB BUT WAS TOLD THERE WASN'T ANY! THIS SEEMS TO BE A MAJOR PROBLEM COMMON IN A WIDE YEAR RANGE OF WRANGLERS. *TR

IT SEEMS THAT FUEL PUMP IN CAR IS NOT WORKING APPROPRIATELY, EVERYTIME I DRIVE VEHICLE IT WANTS TO SHUT DOWN AND THE RADIO SHUTS DOWN OR COMES ON WHEN IT WANTS TOO. *TR

IGNITION LINKAGE ROD (IGNITION TO SWITCH) ON 2004 JEEP WRANGLER UNLIMITED & JEEP LIBERTY IS POORLY MADE OF WEAK POT METAL MATERIAL AND IS EASILY BROKEN. KEY WILL TURN TO ON POSITION (SOMETIMES) BUT CAN NOT ENGAGE SWITCH. LINKAGE ROD NEEDS TO BE MADE OF STRONGER MATERIAL OR BE MADE SLIGHTLY THICKER (WHICH WOULD ALSO REQUIRE A REDESIGN OF THE SWITCH'S RECEIVER HOLE) TO BE ABLE TO HANDLE THE STRAIN OF TURNING THE IGNITION SWITCH. PART IS ALSO HOUSED BEHIND A REMOVABLE HOUSING AND IS MADE TO BE SERVICED (SHOWING THAT THE MANUFACTURER EXPECTED WARE) BUT PART IS NOT AVAILABLE FOR PURCHASE. THE ENTIRE STEERING COLUMN MUST BE REPLACED AT A DEALERSHIP AT AN EXPECTED COST OF $400-$600. THIS IS ONLY ONE SMALL PART THAT SHOULD COST AT MOST AROUND $20 AND IS MADE TO BE REPLACED WHEN THE INEVITABLE BREAKAGE OCCURS. DESPITE THE FREQUENCY OF THIS PROBLEM THE DEALERS SERVICE CENTER STILL CLAIM THAT THIS IS THE FIRST TIME THEY HAVE EVER HEARD OF SUCH A PROBLEM WHILE THE MAN IN THE PARTS DEPARTMENT WAS FAMILIAR ENOUGH WITH IT HE IDENTIFIED THE BROKEN PART BEFORE I COULD TELL HIM MYSELF WHAT IT WAS. HE EVEN ASKED IF I WAS THE SAME GUY THAT HAD BEEN IN LAST WEEK WITH THE SAME COMPLAINT, WHICH I AM NOT. FIRST TIME REPORTING A FAULTY PART, MY SITUATION ALONG WITH HUNDREDS OF REPORTS I HAVE READ ONLINE HAS CONVINCED ME THIS IS WORTHY OF A RECALL. *TR

WHILE TURNING LEFT AT AN INTERSECTION AT 5 MPH, ENGINE STALLED. THIS HAPPENED TWICE. MECHANIC SCANNED ENGINE WITHOUT FINDING CAUSE. *TR

I TOOK MY 2004 JEEP GRAND CHEROKEE BACK TO THE DEALER BROWN'S JEEP IN MEDFORD NY BECAUSE IT WOULD CONTINUOUSLY STALL AND THE YELLOW DASHBOARD LIGHT WOULD STAY ON. THE PROBLEM BEGAN AT APPROX 50,000 MILES AND THE DEALER NEW EXACTLY WHAT IT WAS; A THROTTLE SENSOR ON A CIRCUIT BOARD. THE SUV WOULD RACE AND BUCK AND WAS DIFFICULT TO CONTROL. IT SEEMED ODD THAT THEY NEW WHAT IT WAS RIGHT AWAY AND HAPPENED TO A RELATIVELY LATE MODEL VEHICLE. AND NOW I SAW AN ARTICLE IN THE NEWSPAPER ABOUT THE NHTSA INVESTIGATING STALLING OF JEEP SUVS. IT COST ME APPROX. $400-$500 OF THE $1150 I PAID FOR THE SERVICE VISIT ATTRIBUTABLE TO FIXING THE STALLING ISSUE. PERHAPS THE JEEPS YOU ARE INVESTIGATING ARE NOT THE ONLY YEARS INVOLVED. *TR

I OWN A 2004 JEEP WRANGLER WITH A 4.0 I-6 ENGINE. WITHIN THE PAST 2 WEEKS, THE VEHICLE HAS STALLED ON THE HIGHWAY 3 DIFFERENT TIMES. THE FOLLOWING APPLIES TO ALL 3 INCIDENTS... ONCE I GOT THE VEHICLE OVER TO THE SHOULDER AND STOPPED, THE ENGINE WOULD NOT RESTART. THE VEHICLE WAS TOWED TO A DEALER WHERE THE CRANKSHAFT POSITION SENSOR WAS DIAGNOSED AS FAULTY AND THUS REPLACED. THE CRANKSHAFT POSITION SENSOR WAS REPLACED THREE TIMES. ALL 3 INCIDENTS OF FAILURE HAVE OCCURRED AT HIGHWAY SPEEDS. THIS RAISES MY SAFETY CONCERN SINCE I CAN NOT ACCELERATE AND SAFELY PULL TO THE SHOULDER, ESPECIALLY WHEN THE SURROUNDING VEHICLES ARE AT HIGHWAY SPEEDS. THE INCIDENT DATE POSTED WAS THE DATE OF THE THIRD AND MOST RECENT INCIDENT THE SECOND INCIDENT OCCURRED ON MAY 23, 2004 AND THE FIRST INCIDENT OCCURRED ON MAY 18, 2004. *JB
