2018 Buick Enclave crash-test ratings
NHTSA 5-Star Safety Ratings for the tested versions. More stars mean a lower chance of serious injury in that type of crash. Rollover risk is NHTSA's estimated chance of rolling over in a single-vehicle crash.
| Tested vehicle | Overall | Frontal | Side | Rollover | Rollover risk | Forward collision warning |
|---|---|---|---|---|---|---|
| 2018 Buick Enclave SUV AWD | 5 stars | 4 stars | 5 stars | 4 stars | 15% | Optional |
