How many miles will a 1999 Sienna last?
The 67 mileages owners gave run from 62 to 305,000 miles. A quarter are at or under 61,000 miles, half at or under 90,000, three quarters at or under 118,580 and nine in ten at or under 150,000; 24 (36%) came after 100,000 miles, 5 (7%) after 150,000 and 1 (1%) after 200,000.
These mileages say when owners reported a problem, not when a 1999 Sienna 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 Sienna a good year?
Complaint counts cannot say whether the 1999 is a good or a bad Sienna: 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 215 complaints, the 1999 ranks 12th of the 29 Toyota Sienna model years from 1998 to 2026 with 10 or more complaints, counting from the most. The most: the 2004 (2,062). The fewest: the 2026 (21).
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.

1999 Toyota Sienna recalls
NHTSA's recall files of November 11, 2026 list 3 recall campaigns that name the 1999 Toyota Sienna (2 vehicle campaigns and 1 equipment or tire campaign that names this model year, often for aftermarket parts). 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 Sienna 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 Sienna.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 148 of the 215 complaints on the 1999 Toyota Sienna give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA names counted: SIENNA and SIENNA HYBRID. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file names matched: SIENNA and SIENNA HYBRID.
