Model records

What changes the warranty calculation

The Mercedes-Benz GLS 450 records contain 186 submitted complaints across 10 matched model years. The median is 15.5 reports per matched year. NHTSA source snapshot: 2026-10-18.

The 2020 record contains 36 complaint reports, the highest raw count among matched years here; other years may tie. Vehicle sales and time on the road differ, so this comparison does not establish a failure rate.

Engine replacement or major internal repair has the highest arithmetic midpoint for parts in the applicable planning estimates, at $8,000 before labor. Confirm the configuration and remaining factory coverage before using this broad estimate to compare a service contract.

66 recall/model-year entries. A campaign can cover several years; the unique campaign count removes that repetition. Missing model-name matches remain unavailable.
