Porsche 911 Turbo: which years to buy, and what breaks on them
Best and worst years of the Porsche 911 Turbo
Of the 3 model years of the Porsche 911 Turbo that carry enough owner reports to score, 2002 comes out best at 77 out of 100 and 2007 worst at 80. The scores rank each year against other cars of the same model year, so an older one is not penalised for having had longer to break.
89 owner reports across 16 model years, 83 of them carrying an odometer reading. 3 years carry enough reports to score.
The year to buy, and the year to avoid
Both figures are ranks against other vehicles of the same model year, so the two are comparable even when the years are a decade apart. Each links to that year's full report.
2002 Porsche 911 Turbo
Best of 16 years on 16 owner reports, its own worst problem being other engine problem. Evidence behind the score: low confidence.
2007 Porsche 911 Turbo
Risk 80 of 100 from 25 reports, worst problem radiator or coolant leak.
Severe Moderate confidence confidence
How much the year actually matters
The gap between the best and worst year is 4 points on a 100-point scale, which is small enough that the year is a weak reason to choose one of these over another. Service history will tell you more.
Across every year of the Porsche 911 Turbo, owners have filed 89 reports with NHTSA. The 2001 accounts for the largest share at 26, which can mean a genuinely troublesome year or simply the year that sold best and has been on the road longest.
What tends to break across the Porsche 911 Turbo
Taking the most-reported failure from each model year, the recurring problems on the Porsche 911 Turbo are other engine problem (worst mode in 4 years), radiator or coolant leak (worst mode in 2 years) and other body or interior problem (worst mode in 1 year). A fault that heads the list in most years is characteristic of the design; one that heads a single year is usually a batch or a supplier.
Every model year, scored
Shorter is better, and the outlined row is the best year of the line. A year with too few reports to score is shown without a bar rather than as a zero, because no data is not the same as no problems.

What each column means
Reports counts owner complaints filed with NHTSA against that model year. Filing is voluntary and unverified, so the count is a floor on how often something went wrong, never a census. It also rises with how many cars were sold, which is why the next column exists.
Per 1,000 divides those reports by an estimate of how many of that model year are on the road, so a common car and a rare one can be compared. The estimate comes from the vehicle counts in recall campaigns covering the same model year, which is the only per-model fleet figure published free of charge; where no recall covers a year, this column is blank rather than guessed.
Median report is the odometer reading at the midpoint of that year's reports: half of the readings owners gave were below it. It is a description of when problems get reported, not a prediction of when this car will break, and it needs at least eight readings before it is shown at all.
Risk is a 0–100 score combining how often reports arrive relative to fleet size, how serious they are, and how early they land, ranked against other vehicles of the same model year only. Confidence says how much evidence sits behind it: a low score on thin evidence is a shrug, not a clean bill of health. Both are defined in full on the methodology page.
Generations, and why the boundary matters
The Porsche 911 Turbo splits into generations: 2001–2003 (best 2002, worst 2001), 2004–2007, 2008–2013, 2017 and 2022–2023. Comparing years inside one generation is the fair comparison — same body, same engines, usually the same suppliers.
Generation boundaries here are inferred from the pattern of model years in the data rather than taken from manufacturer documentation, so they are occasionally a year out. Where a boundary matters to a purchase, check it against the build date on the car.
| Generation | Years | Best year | Worst year | Spread |
|---|---|---|---|---|
| 2001-2003 | 2001–2003 | 2002 Porsche 911 Turbo 77 | 2001 Porsche 911 Turbo 78 | 1 |

How to use this page
The honest way to read a table like this is worst-first: rule out the years with high scores and heavy complaint volume, then choose among the rest on condition, history and price. A low score is not a promise, and a high one is not a verdict on the specific car in front of you.
Every figure comes from owner complaints filed with NHTSA and from recall records, both voluntary in the sense that nobody audits them for completeness. Counts are floors. The AtWhatMileage methodology page sets out each formula.
Questions this page answers
What is the best year for the Porsche 911 Turbo?
Of the model years we can rate, 2002 Porsche 911 Turbo scores best at 77 out of 100, based on 16 owner reports. 2007 scores worst at 80.
Which years of the Porsche 911 Turbo should you avoid?
2007 has the highest risk score in this model line at 80 out of 100. The scores compare each year against other vehicles of the same model year, so they are not affected by age alone.
How the generations are drawn. NHTSA does not publish generation boundaries, so ours are inferred from breaks in the recall and complaint record and from the model's own year range. They are close to the enthusiast consensus but not authoritative — if a boundary looks wrong for a car you know well, tell us and we will fix the table rather than argue with you.
