Common problems with the 2003 L300
NHTSA's file holds 42 owner complaints on the 2003 Saturn L300. Owners named the electrical system most often: 10 complaints, and half of the 10 that list a mileage came after 84,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Electrical System | 10 | 10 | 84,500 |
| Exterior Lighting | 10 | 7 | 112,000 |
| Engine | 5 | 5 | 93,000 |
| Engine And Engine Cooling | 4 | 3 | Under 5 mileages |
| Vehicle Speed Control | 4 | 4 | Under 5 mileages |
Of the 42 complaints, 5 report a crash, 4 report a fire and 3 report an injury (4 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2003 L300
The 35 mileages owners gave run from 8 to 160,800 miles. A quarter are at or under 28,500 miles, half at or under 61,500, three quarters at or under 100,000 and nine in ten at or under 133,000; 8 (23%) came after 100,000 miles, 1 (3%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2003 L300 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: 27 of the 35 came at or under 100,000 miles, so they say nothing about how many miles a 2003 L300 can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 8 miles |
| 25th percentile | 28,500 miles |
| Median (50th percentile) | 61,500 miles |
| 75th percentile | 100,000 miles |
| 90th percentile | 133,000 miles |
| Highest mileage listed | 160,800 miles |
| Complaints after 100,000 miles | 8 (23%) |
| Complaints after 150,000 miles | 1 (3%) |
| Complaints after 200,000 miles | none |
Is the 2003 L300 a good year?
Complaint counts cannot say whether the 2003 is a good or a bad L300: 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 42 complaints, the 2003 ranks 2nd of the 3 Saturn L300 model years from 2003 to 2005 with 10 or more complaints, counting from the most. The most: the 2004 (61). The fewest: the 2005 (25).
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 Saturn L300 recalls
NHTSA's recall files of November 11, 2026 list no campaign for the 2003 model year under the name L300. Recalls can be filed under another name (a trim, a body or a series name), so a recall may still exist for the 2003 Saturn L300: 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 L300 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 L300.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 7 of the 42 complaints on the 2003 Saturn L300 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: L300. 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: L300.
