NHTSA Complaint #11434506 — 2020 MERCEDES-BENZ SPRINTER 2500

On Sept 6 2021 the engine suddenly stalled/stopped while driving on 194 west of Pullman Wa. A partial restart enabled me to move to a safer location. The Check Engine light came on. I used myOBD scanner to identify engine failure fault codes. Electrical sensor short circuits were identified. Vehicle was transported to a MB dealer in Spokane where a chaffed engine wiring harness was identified as the cause. MB engineers in Stuttgart Germany confirmed this diagnosis. I have now learned that the factory harness installation rubbing against engine components has been an ongoing problem in the Sprinter Van. This defect has contributed to engine failures as acknowledged by several MB technicians. Owners of all affected MB Sprinter Vans should receive notice of this potentially dangerous wiring harness defect. MB USA should be mandated to recall and modify the harness attachment points where abrasion of the harness cover and wiring is occurring. Preventing unexpected engine shutdowns in Highway traffic must be a priority of any vehicle manufacturer. Rear end collisions endanger the safety and lives of vehicle occupants. The defective engine wiring harness installation should be addressed immediately. Please share my report with MB USA. Accident Prevention Saves Lives
