ANALYSISHow safe is the 2021 Mercedes-Benz Glc?

The 2021 Mercedes-Benz GLC enters the MotorCaliber dataset with a notable zero-recall history, contributing to a strong defect record sub-score of 18.5 out of 20. This clean slate anchors its overall Safety Index at 92/100, placing it in the Exceptional band. Its crash protection also scored highly, earning 66 out of 70. While its core safety is robust, the GLC's avoidance technology presents a mixed picture. A sub-score of 7 out of 10 reflects standard forward collision warning and electronic stability control. However, the absence of lane departure warning as standard equipment prevents a higher rating in this category. Owner complaints for the 2021 GLC total 61. Of these, 29 allege engine-related issues. Despite this concentration, no recall has been issued for these concerns. A single reported fire allegation remains an unverified consumer claim. Based on the ratings NHTSA published, the 2021 Mercedes-Benz GLC demonstrates one of the stronger safety profiles within the mid-size luxury SUV segment.

NCAP // CRASH TESTHow did the 2021 Mercedes-Benz Glc perform in crash tests?

The 2021 Mercedes-Benz GLC achieved a five-star overall safety rating from NHTSA, demonstrating strong performance in collision scenarios. Frontal and side impact tests each yielded a perfect five-star score.

The dynamic tip test, by contrast, recorded a "No Tip" result.
