Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023-2026 EQE and GLC vehicles. Please see the recall report for a complete list of models. The steering coupling bolt may have been improperly tightened, allowing the steering coupling to loosen from the steering rack.
Consequence: A loose steering coupling can cause a loss of steering control, increasing the risk of a crash.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2022: 35 complaints · 2023: 53 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
