2003 MUSTANG COBRA , 600 PLUS MILES, WAS DRIVING AT AROUND 32 MILES AN HOUR WHEN I PUSHED IN THE CLUTCH TO SHIFT AND THE CAR DIED, WHICH LOCKED UP THE STEERING WHEEL, NEEDLESS TO SAY THIS IS EXTREMELY DANGEROUS, AND LUCKILY NO ONE WAS HURT. THE LOCAL DEALER HAS NO CLUE HOW TO FIX THIS, AND SUPPOSEDLY SVT IS WORKING ON A FIX BUT IN THE MEAN TIME THERE ARE OVER 13000 OF THE CARS DRIVING ON THE ROADS WAITING TO CAUSE AN ACCIDENT. PLEASE ADDRESS THIS PROMPTLY THANKS. *LA

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.
