NHTSA Complaint #11091168 — 2012 JEEP WRANGLER

CHECK ENGINE ILLUMINATED IN MID-2017, BUT NO CODES WERE PRESENT AND JEEP APPEARED TO RUN FINE. IN SEPT 2017, WHILE DRIVING ON I-75, THE JEEP SHUDDERED AND THE ELECTRONIC THROTTLE CONTROL LIGHT CAME ON, ALONG WITH THE ANTI-LOCK BRAKE SYSTEM LIGHT. I TOOK IT TO THE JEEP DEALERSHIP IMMEDIATELY, BUT THEY COULDN'T FIGURE OUT THE PROBLEM BECAUSE THE LIGHTS HAD TURNED OFF. THEY ENDED UP SWAPPING OUT THE SPARK PLUGS AND TWO IGNITION COILS. THE CHECK ENGINE LIGHT CAME BACK ON A FEW DAYS LATER. I WAS ABLE TO PULL CODES FOR THE THROTTLE POSITION SYSTEM 1 AND 2. IN OCT 2017, THE VEHICLE JUMPED/SHUDDERED AND STOPPED RUNNING. I HAD TO COAST TO THE SHOULDER AND LEAVE IT SIT FOR 10 MINUTES. I WAS ABLE TO RESTART THE VEHICLE AND DRIVE IT A LOCAL REPAIR SHOP WHERE THEY WERE UNABLE TO PULL ANY CODES AND BASED OFF OF MY DESCRIPTION OF THE ISSUES, REPLACED THE PEDAL ASSEMBLY AND CLEARED THE CODES. THEY SAID IF THE ISSUE CAME BACK TO REPLACE THE BATTERY. THE ISSUE CAME BACK WITHIN 5 MINUTES OF LEAVING THE AUTOMOTIVE GARAGE, SO I CHANGED THE BATTERY IN NOVEMBER. AFTER THAT, THE CHECK ENGINE LIGHT WHEN AWAY, BUT WOULD COME BACK ON SPORADICALLY. THE JEEP WAS STILL SHUDDERING/JUMPING AND WOULD THEN COMPLETELY STOP AFTER THE CHECK ENGINE LIGHT, THE ELECTRONIC THROTTLE CONTROL, AND THE ANTI-LOCK BRAKE SYSTEM NOTIFICATION, STILL. I JUST TOOK IT TO ANOTHER GARAGE (ARIL 2018), SINCE THE PREVIOUS TWO HAD NO IDEA WHAT THE ISSUE WAS. AT THIS POINT I WAS STILL PULLING THROTTLE POSITION 1 AND 2 CODES. THIS GARAGE REPLACED THE ENTIRE THROTTLE BODY AND RAN A FUEL INJECTION SERVICE. WITHIN 15 MINUTES OF ME DRIVING AWAY FROM THAT GARAGE, THE CHECK ENGINE LIGHT CAME ON, FOLLOWED BY A SOFTER SHUDDER OF THE VEHICLE AND THE ELECTRONIC THROTTLE CONTROL LIGHT. I TRIED TO PULL CODES WHEN I GOT HOME, BUT THERE WERE NONE--BUT THE CHECK ENGINE LIGHT AND THE ELECTRONIC THROTTLE CONTROL LIGHT ARE STILL ON.
