Mileage when owners reported a problem with the 1991 LeSabre
Too few complaints on the 1991 LeSabre list a mileage to say when owners reported problems: 4 of its 30 complaints list a mileage (57,343 to 172,000 miles), and a median is given here only with 10 or more.
These mileages say when owners reported a problem, not when a 1991 LeSabre 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.
Every model year together: Half of the 1,539 NHTSA owner complaints on the Buick LeSabre that list mileage came after 64,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Buick LeSabre last? →
Is the 1991 LeSabre a good year?
Complaint counts cannot say whether the 1991 is a good or a bad LeSabre: they rise with how many were sold and how long they have been on the road. They show how the 1991 compares with the other model years in NHTSA's file.
With 30 complaints, the 1991 ranks 17th of the 20 Buick LeSabre model years from 1986 to 2005 with 10 or more complaints, counting from the most. The most: the 2000 (669). The fewest: the 1986 (16).
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 |
|---|---|---|---|
| 1986 LeSabre | 16 | 0 | Under 10 mileages |
| 1987 LeSabre | 40 | 0 | Under 10 mileages |
| 1988 LeSabre | 21 | 2 | Under 10 mileages |

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 1991 LeSabre 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 1991 LeSabre.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 26 of the 30 complaints on the 1991 Buick LeSabre 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: LESABRE. 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: LESABRE.
