NHTSA Complaint #11180241 — 2017 JEEP RENEGADE

2017 JEEP RENEGADE WITH 42,000 MILES HAS FAULTY IGNITION COILS, CAUSING THE VEHICLE TO MISFIRE, AND STALL WHILE DRIVING. AFTER OUR JEEP RENEGADE STARTED RUNNING ROUGH AND MISFIRING, I STARTED RESEARCHING POSSIBLE ISSUES. SHORTLY AFTER THIS THE CHECK ENGINE LIGHT INDICATED A PROBLEM, WHICH DISABLED THE 4 WHEEL DRIVE IN THE VEHICLE DURING A SNOWSTORM HERE. UPON PULLING THE CEL CODE, WE FOUND A MISFIRE IN CYLINDER 2 AND REPLACED THE SPARK PLUGS AS THIS IS A TYPICAL SOLUTION TO MINOR IGNITION ISSUES. UPON REPLACEMENT, I NOTICED ONE PLUG WAS BADLY FOULED AND CORRODED WITH ANOTHER HAVING SLIGHT FOULING. AFTER REPLACEMENT OF THE SPARK PLUGS, THE VEHICLE ACTED OK FOR ABOUT AN HOUR THEN STARTED MISFIRING AGAIN. WE SWAPPED THE 2 AND 4 COIL WITH EACH OTHER RESULTING IN THE MISFIRE MOVING TO CYLINDER 4. THIS LEXUS TO REPLACE THE IGNITION COILS SOLVING THE ISSUE. THIS VEHICLE HAS LESS THAN 50,000 MILES ON IT, AND UPON FURTHER RESEARCH WE ARE FINDING THIS IS A COMMON PROBLEM WITH THE RENEGADE IGNITION COILS FAILING PREMATURELY CAUSING THE VEHICLE TO MISFIRE AND STALL. THIS IS A POTENTIAL LIFE THREATENING ISSUE BECAUSE IF THE VEHICLE STALLS WHILE DRIVING COULD VERY LIKELY CAUSE ACCIDENTS. ADDITIONALLY THE FAILURE OF THE 4WD WITH ACEL PUTS THE DRIVER AT FURTHER RISK OF BEING STUCK OR CAUSING A WRECK WHEN THE VEHICLE DOES NOT PERFORM AS EXPECTED.
