Common problems with the 2001 TT
NHTSA's file holds 120 owner complaints on the 2001 Audi TT. Owners named the electrical system most often: 71 complaints, and half of the 44 that list a mileage came after 47,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Electrical System | 71 | 44 | 48,000 |
| Air Bags | 10 | 10 | 40,675 |
| Engine And Engine Cooling | 10 | 8 | 69,700 |
| Power Train | 7 | 5 | 49,200 |
| Suspension | 6 | 4 | Under 5 mileages |
Of the 120 complaints, 4 report a crash, 3 report a fire and 2 report an injury (2 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2001 TT
The 77 mileages owners gave run from 25 to 194,000 miles. A quarter are at or under 31,600 miles, half at or under 50,000, three quarters at or under 82,195 and nine in ten at or under 100,000; 6 (8%) came after 100,000 miles, 1 (1%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2001 TT wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: 71 of the 77 came at or under 100,000 miles, so they say nothing about how many miles a 2001 TT can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 25 miles |
| 25th percentile | 31,600 miles |
| Median (50th percentile) | 50,000 miles |
| 75th percentile | 82,195 miles |
| 90th percentile | 100,000 miles |
| Highest mileage listed | 194,000 miles |
| Complaints after 100,000 miles | 6 (8%) |
| Complaints after 150,000 miles | 1 (1%) |
| Complaints after 200,000 miles | none |
Is the 2001 TT a good year?
Complaint counts cannot say whether the 2001 is a good or a bad TT: they rise with how many were sold and how long they have been on the road. They show how the 2001 compares with the other model years in NHTSA's file.
With 120 complaints, the 2001 drew the most of the 8 Audi TT model years from 2000 to 2009 with 10 or more complaints. The fewest: the 2005 (11).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2000 TT | 73 | 33 | 70,231 |
| 2001 (this page) | 120 | 77 | 50,000 |
| 2002 TT | 38 | 26 | 41,000 |
| 2003 TT | 13 | 9 | Under 10 mileages |
| 2004 TT | 25 | 23 | 55,501 |
| 2005 TT | 11 | 8 | Under 10 mileages |
| 2008 TT | 14 | 11 | 24,800 |
| 2009 TT | 12 | 12 | 20,000 |

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2001 TT lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2001 TT.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 43 of the 120 complaints on the 2001 Audi TT give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: TT. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: TT.
