Mercedes-Benz Gls-Class
NHTSA safety across every Mercedes-Benz Gls-Class model year we cover.
Across the 5 model years of the Mercedes-Benz Gls-Class we cover (2019 to 2023), no year has an NHTSA crash-test score on record. No recalls are on record across those years.
The Mercedes-Benz GLS-Class is a full-size, three-row luxury SUV positioned at the top of Mercedes-Benz's SUV lineup. Aimed at affluent families and executive buyers who want genuine eight-passenger capacity without sacrificing premium refinement, the GLS competes in one of the most demanding segments in the market, where comfort, technology, and safety presence all matter equally.
From a pure safety-data standpoint, the 2019-2023 Mercedes-Benz GLS-Class presents a notably thin picture at MotorCaliber. NHTSA did not crash-test any model year we cover, which means there are no federal star ratings to anchor a safety assessment. That is a real gap for shoppers who rely on independent crash-test validation, and it is worth taking seriously regardless of the vehicle's premium positioning or the brand's engineering reputation. On the recall front, the GLS-Class posts a clean record across all five covered model years, with zero NHTSA recalls issued. That is a genuinely positive data point and stands out even among luxury competitors. Owner complaints across 2019-2023 total 125, which is a moderate figure for a vehicle sold in relatively low volumes compared to mainstream SUVs. Within those 125 complaints, shoppers should note eight alleged crashes, six alleged fires, and seven alleged injuries. NHTSA labels these unverified allegations, and volume context matters, but six fire-related complaints across five model years is a pattern worth monitoring before purchase. No deaths were reported. Bottom line: the GLS-Class earns credit for zero recalls, but the absence of crash-test data is a legitimate concern for safety-first buyers. The complaint log is manageable, but the fire-related allegations deserve attention. Shoppers should check NHTSA's database for any updates before finalizing a purchase.
WHAT REVIEWERS SAYReviewers generally regard the GLS-Class as one of the most polished and well-appointed three-row SUVs available, praising its cabin materials, ride refinement, and commanding road presence. Most find the driving dynamics surprisingly composed for a vehicle of its size. Value relative to ultra-luxury rivals is frequently cited as a strength, though some reviewers note the technology interface has a steep learning curve.
- NHTSA has not crash-tested any 2019-2023 GLS-Class model year, meaning there are no federal star ratings available. Shoppers seeking independent crash-test validation should check whether IIHS has tested the relevant model year before buying.
- The GLS-Class recorded zero NHTSA recalls across all five covered model years, a strong result that suggests Mercedes-Benz did not identify any widespread safety defects requiring a federal corrective action during this period.
- Owner complaints include six alleged fire-related incidents across 2019-2023. These are unverified allegations in the NHTSA database, but the pattern is worth monitoring. Prospective buyers should review the specific complaint narratives on NHTSA's website for additional context.
- With 125 total owner complaints and eight alleged crashes reported over five model years, the GLS-Class complaint volume is relatively contained for a full-size luxury SUV. However, the seven alleged injuries within that complaint pool underscore the importance of reviewing any open investigations before purchase.
