5th generation (S197) · S197 (Ford D2C) · 4,930 complaints, 2,795 with mileage
Owners filed 4,930 complaints with NHTSA about the 2005–2014 Ford Mustang, and 2,795 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
Failures are spread across the mileage range, with the middle half between 9,500 and 70,000 miles. The median is 39,000 miles.
The most-reported areas are the airbag system (41.5% of complaints, typically around 45,000 miles), the transmission and driveline (12.3% of complaints, typically around 10,000 miles), the electrical system (8.2% of complaints, typically around 60,000 miles).

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 39,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
The airbag system accounts for 41.5% of complaints (2,045 reports, 405 of them with a mileage figure), with a median of 45,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 20,000 and 82,000 miles.
A single system taking 41.5% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.
The transmission and driveline accounts for 12.3% of complaints (608 reports, 533 of them with a mileage figure), and it fails early — a median of 10,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 2,000 and 45,100 miles.
The electrical system accounts for 8.2% of complaints (404 reports, 331 of them with a mileage figure), and it fails late — a median of 60,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 38,000 and 80,000 miles.
Throttle and speed control accounts for 5.8% of complaints (287 reports, 249 of them with a mileage figure), with a median of 44,354 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 16,694 and 70,000 miles.
Body structure accounts for 4.8% of complaints (236 reports, 192 of them with a mileage figure), with a median of 38,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 15,474 and 65,358 miles.
The engine accounts for 3.7% of complaints (180 reports, 156 of them with a mileage figure), and it fails late — a median of 57,900 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 32,651 and 76,000 miles.
Within this generation, complaint volume is not constant across model years. The 2005 model year drew the most — 893 complaints — while 2009 drew the fewest at 215. The median year sits at 466.
The first year of the generation, 2005, sits above the median. That is a common pattern — early production of a redesigned vehicle tends to surface problems that later years do not repeat — and it is worth weighing when choosing between years.
NHTSA records 8 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
The campaigns cluster around the airbag system (6), the transmission and driveline (1), the exterior lighting (1). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.
Of the 4,930 complaints filed against this generation, 345 reported a crash; 36 reported a fire; 260 reported an injury; 9 reported a fatality. Crash-involved reports represent 7.0% of the total.
These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 9,500 and 70,000 miles, with a median of 39,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the airbag system and the transmission and driveline are where this generation's reports concentrate, so those are the areas worth a specific look. The transmission and driveline in particular shows a median failure mileage of 10,000, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.
MT82 6-speed manual notchy and grinding shifts, gear clash, 1-2 nibble and high-rpm lockout, worst when cold; Ford issued multiple TSBs revising the fluid, shifter and internals.
4.6L 3V variable cam timing phaser rattle and timing chain tensioner/guide wear producing a cold-start rattle.
4.0L SOHC V6 timing chain guide and tensioner wear (long chain runs to the rear-mounted cam drive), causing rattle and eventual timing failure.
