20V395000 · Electronic Stability Control (Esc) | Electrical System:Software
Reported: 2020-07-06 (July 6, 2020)
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2019-2020 C63 AMG, C63 AMG S, AMG GT 53, AMG GT 63, AMG GT 63 S, and 2020 GLC 63 AMG, GLC 63 AMG S vehicles. An incorrect Electronic Stability Program (ESP) software version may cause the ESP system to react inaccurately. On December 18, 2020, an additional 360 vehicles were added to the recall population.
Consequence: If the ESP does not react properly to a driving situation, it may increase the risk of a crash.
Remedy: MBUSA will notify owners, and dealers will update the ESP software, free of charge. The recall began August 28, 2020. Letters for the owners of the 360 additional vehicles were mailed January 15, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2020080016.

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.
2020: 1 complaints · 2021: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
|---|---|---|---|
| 2020 | 1 | 1 | 1 |
