How many miles will a 2003 Highlander last?
The 213 mileages owners gave run from 1 to 216,616 miles. A quarter are at or under 50,000 miles, half at or under 93,500, three quarters at or under 122,200 and nine in ten at or under 146,000; 85 (40%) came after 100,000 miles, 18 (8%) after 150,000 and 4 (2%) after 200,000.
These mileages say when owners reported a problem, not when a 2003 Highlander 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 2003 Highlander a good year?
Complaint counts cannot say whether the 2003 is a good or a bad Highlander: they rise with how many were sold and how long they have been on the road. They show how the 2003 compares with the other model years in NHTSA's file.
With 258 complaints, the 2003 ranks 11th of the 25 Toyota Highlander model years from 2001 to 2025 with 10 or more complaints, counting from the most. The most: the 2006 (649). The fewest: the 2025 (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.

2003 Toyota Highlander recalls
NHTSA's recall files of November 11, 2026 list 2 recall campaigns that name the 2003 Toyota Highlander. 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 2003 Highlander 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 2003 Highlander.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 45 of the 258 complaints on the 2003 Toyota Highlander 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: HIGHLANDER and HIGHLANDER 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: HIGHLANDER and HIGHLANDER HYBRID.
