Model records
What changes the warranty calculation
Across 12 model years, the GMC Sierra 2500 records contain 587 complaints. The median count per model year is 40 reports. These figures do not account for annual sales.
The 2024 record contains 101 complaint reports. No listed year has a higher raw count, though other years may be tied. This comparison uses all listed years without adjusting for sales or time on the road; it does not establish a failure rate.
Engine replacement or major internal repair has the highest midpoint parts estimate in the applicable list, at $7,000. Check the remaining factory coverage before paying for an extra plan that overlaps with it.
