Mileage when owners reported a problem with the 1999 Trans Sport
Too few complaints on the 1999 Trans Sport list a mileage to say when owners reported problems: 4 of its 10 complaints list a mileage (900 to 57,000 miles), and a median is given here only with 10 or more.
These mileages say when owners reported a problem, not when a 1999 Trans Sport 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.
Is the 1999 Trans Sport a good year?
Complaint counts cannot say whether the 1999 is a good or a bad Trans Sport: they rise with how many were sold and how long they have been on the road. They show how the 1999 compares with the other model years in NHTSA's file.
With 10 complaints, the 1999 drew the fewest of the 10 Pontiac Trans Sport model years from 1990 to 1999 with 10 or more complaints. The most: the 1997 (236).
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 |
|---|---|---|---|
| 1990 Trans Sport | 45 | 1 | Under 10 mileages |
| 1991 Trans Sport | 36 | 2 | Under 10 mileages |
| 1992 Trans Sport | 76 | 4 | Under 10 mileages |
| 1993 Trans Sport | 61 | 2 | Under 10 mileages |
| 1994 Trans Sport | 98 | 5 | Under 10 mileages |
| 1995 Trans Sport | 113 | 17 | 87,430 |
| 1996 Trans Sport | 61 | 16 | 95,028 |
| 1997 Trans Sport | 236 | 58 | 86,014 |
| 1998 Trans Sport | 227 | 67 | 80,000 |
| 1999 (this page) | 10 | 4 | Under 10 mileages |
1999 Pontiac Trans Sport recalls
NHTSA's recall files of November 11, 2026 list 2 recall campaigns that name the 1999 Pontiac Trans Sport. A campaign covers a production range, not every vehicle of the model year: check the VIN with NHTSA's free recall lookup.
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 1999 Trans Sport 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 1999 Trans Sport.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 6 of the 10 complaints on the 1999 Pontiac Trans Sport 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: TRANS SPORT. 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: TRANS SPORT.
