How many miles is too much for a used Sierra 2500?
There is no hard cutoff. NHTSA's file records when owners reported problems, not when a Sierra 2500 wears out, and how a car was maintained matters more than any one odometer figure.
Where the complaints cluster: the middle half came between 34,000 and 101,000 miles, and 9% came after 150,000 miles (100 of 1,149).
Complaint mileage rises with a model year's age: older Sierra 2500 years were reported at higher odometer readings because they had more time to cover miles. The table below shows when owners of each year reported problems; it does not rank the years.
GMC Sierra 2500 mileage at failure by model year
Each row is a Sierra 2500 model year with 10 or more NHTSA complaints that list a mileage, with the median of those mileages: half of the year’s complaints came at or above it. Years with fewer are left out. Medians rise with a year’s age, so the table does not rank the years. A linked year opens that model year’s own page: its problems by component and its recall campaigns.

What these mileages can and cannot tell you
- They are self-reported. The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- They are not a lifespan study. The file holds only cars whose owners reported a problem; a Sierra 2500 that ran without one never appears in it, so these figures do not say how long a typical Sierra 2500 lasts.
- Young model years pull the figures down: a car a few years old cannot have reached high mileage when its owner complained.
- A complaint is an allegation, not a defect finding, and the count rises with how many cars were sold.
- 692 of the GMC Sierra 2500 complaints in these model years give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every figure.
- NHTSA also holds 1 complaint for 1994, fewer than 10 a year under a name whose typical year draws 40 or more; those stray filings are left out.
- NHTSA names counted: SIERRA 2500 and SIERRA 2500 HD. Complaints filed under the bare SIERRA name name no weight class and are not counted.

How do I check the mileage of a used Sierra 2500?
Compare the odometer with the readings on file for its VIN: title transfers, inspections and auction sales record the mileage on the day. A reading lower than an earlier one, or a long gap, is worth asking about. VIN Lookup (free-vin-lookup.com) sells the original ClearVIN PDF for $14.99 (3 reports for $29.99, 5 for $44.99): odometer readings, title brands and auction records on file for the VIN.
