2021 Chevrolet Suburban
Federal crash-test performance, recalls, and complaints, scored into one NHTSA Safety Index.
The Chevrolet Suburban is a full-size body-on-frame SUV that has defined the segment for decades. Built to haul families, tow heavy loads, and cover long distances in comfort, it targets buyers who need genuine three-row capacity and serious capability. The 2021 to 2025 generation represents the current platform, and for shoppers weighing this large SUV, the safety picture deserves a close look before signing anything.
The 2021 Chevrolet Suburban earns an NHTSA Safety Index of 70 out of 100, an average result driven by its federal crash-test stars and its recall record. It has 12 recalls on record, reflected in the score.
- urban drivers exposed to side-impact risk
Reviewers generally praise the Suburban for its cavernous interior, strong towing capability, and refined long-distance ride quality. Most acknowledge it as a benchmark for full-size SUV utility. The consensus also notes that its large footprint can make urban driving challenging, and some reviewers flag that its size and ride height come with handling tradeoffs compared to car-based crossover alternatives.
