THE 6-SPEED MANUAL TRANSMISSION IN MY BRAND NEW 2008 JEEP WRANGLER UNLIMITED MAKES NOISE, AND VIBRATES HORRIBLY GOING OVER ROUGH ROADS! THE SHIFTER SLAMS BACK AND FORTH MAKING CONTACT WITH METAL UNDERCARRIAGE. THE DEALER SAYS THEY KNOW OF THIS PROBLEM BUT CHRYSLER CURRENTLY HAS NO FIX AND THAT IT CAN EVEN POP OUT OF GEAR OVER ROUGH TERRAIN-TERRIBLE DESIGN! *TR

TRANSMISSION SIGNALS AN OVER HEATING SITUATION WITH STORED CODE WHEN GOING UP MODERATE ROAD INCLINES. VEHICLE HAS DONE THIS SEVERAL TIMES AND OTHERS WITH LIKE VEHICLE HAVE ALSO EXPERIENCED THIS. DEALERSHIP HAS RETRIEVED AND VERIFIED CODE INDICATING OVERHEATING OF TRANSMISSION HOWEVER HAS NO MANUFACTURER CORRECTIVE ACTION AND COULD NOT DUPLICATE. POSSIBLE FIRE SITUATION IF FLUID BOILS OVER AND OUT OF FILL TUBE AND IGNITES ON EXHAUST SYSTEM BELOW. *TR

FIRE HAZARD - THE FRONT AXLE VENT TUBE IS INCORRECTLY DESIGNED. WHILE INVESTIGATING AN OIL LEAK THE DEALER FOUND THAT THE TUBE HAD BEEN OVERFLOWING, DEPOSITING OIL RESIDUE ON THE FRAME, EXHAUST PIPE AND CATALYTIC CONVERTER. BURNED OIL IS EVIDENT ON THE EXHAUST CROSSOVER PIPE. IN MY OPINION IS ONLY A MATTER OF TIME BEFORE A FIRE STARTS. THE DEALER HAS SEEN OTHER VEHICLES WITH THIS PROBLEM AND PLANS TO LENGTHEN THE TUBE AND PLACE ITS' END IN A LOCATION AWAY FROM THE EXHAUST. I FEEL THIS FLAW SHOULD MERIT EXPEDITED FACTORY REVIEW AND REDESIGN. *TR

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
