The Mercedes-BenzGLS 450 appears in NHTSA's Office of Defects Investigation database with 241 consumer safety complaints and 60 recall campaigns across 8 model years (2017–2024). That averages roughly 30 complaints per model year. Report counts can differ between model years for many reasons; this dataset does not establish the cause of a difference.
Complaint volume on a nameplate alone is not a reliability verdict: a long-running bestseller can accumulate more filings than a low-volume niche model because more vehicles are on the road. The table below shows report counts and published NHTSA crash-test ratings side by side for each model year. The filing-year histogram shows the timing of submitted reports, not a causal trend.
NHTSA has 15 investigation files tied to this model. Investigation records, complaint reports, and recall campaigns each provide different context. Use the official NHTSA VIN lookup and the underlying notices to research a specific vehicle; PlainCars does not infer a vehicle-risk or pricing conclusion from these records.
Complaints by Year
Complaint Filing Trend
NHTSA complaint volume by year filed (not model year).
Filings moved from 60 in 2017-2021 to 177 in 2022-2026, a rise of 195%. That is the 88th percentile of change across the 763 nameplates with enough filings in both windows to compare, where 0 is the steepest fall and 100 the steepest rise.
Filing volume, not a reliability verdict: counts also move with how many vehicles are on the road, how old they are, and whether a recall drew attention. Computed from this portal's NHTSA filing-year records over the same two windows the trend rankings use.
