Mercedes-Benz Recalls 310,667 Cars over Rollaway Risk
Dealers will replace the door lock assembly free of charge after a faulty microswitch can prevent the electronic parking brake from engaging, Mercedes said.
On Thursday, Mercedes-Benz USA recalled 310,667 vehicles because a corroding micro-switch in the driver's door lock fails to detect open doors, preventing the electronic parking brake from engaging automatically.
Mercedes-Benz identified the issue after discovering that moisture ingress causes internal corrosion on micro-switch contact surfaces, with 176 field cases tracked between March 1, 2020 and June 9, 2026.
Impacted models include 2019–2026 A-Class, C-Class, CLE, GLA, GLB, and GLC lines; owners can search their Vehicle Identification Number on NHTSA.gov starting today, July 31, 2026.
Local dealerships will replace the defective door lock assembly free of charge, while Mercedes-Benz will mail official notification letters to affected owners starting September 18, 2026.
While Mercedes-Benz is unaware of any actual rollaway incidents, owners should manually ensure the transmission is in park and the electronic parking brake is engaged before exiting their vehicles.
