I have called the Mercedes dealer in Collierville Tennessee a dozen times and left messages to get the vehicle in for the recall. i cant get a return call from the Sprinter service manager there. very very frustrating and made me loose faith in the brand for customer service and a blatant disregard for my safety.

The 2019+ Mercedes Sprinter EIS (Electronic Ignition System) module is bolted under the driver side dash board to the base of the A pillar where it meets with the firewall. The electrical connector of the module is pointing straight up - this is an issue because any liquids that might spill on the dash (dash cupholder) or any humidity from windshield interior condensation will drip right down the wiring and into the EIS module causing it to short out. _ If the EIS module shorts out, the vehicle will be inoperable until a new unit is fitted. _ The EIS module retails at $1800+ from Mercedes _ Had Mercedes installed the EIS module with the connector facing DOWNWARD - this moisture related issue would not exist. _ There is no drip loop provisions in the wiring. _ Mercedes is aware of the issue as they have created a plastic bag with part number A 638 546 00 35 and they are charging $20 for it. As of right now, Mercedes refuses to fix this issue preventatively. They will only repair it AFTER the EIS module has shorted out. They are refusing to treat this as a warranty claim even though it is clearly a manufacturer defect.

The 2020 Mercedes Sprinter EIS (Electronic Ignition System) module is placed directly to the base of A pillar. Its electrical connector is pointing straight up and cable entry does not have drop loop - this is an issue because any liquids that might spill on the dash (dash cupholder) or any humidity from windshield interior condensation will drip right down the wiring and into the EIS module causing it to short out. If the EIS module shorts out, the vehicle is inoperable and has to be towed to dealership for repair. MB retails EIS module at $1800+ MB knows it’s a product defect. In its service bulletin of LI54.21-N-069524, They had a temporary solution by using an plastic bag (part number A 638 546 00 35) to cover the top connector. As of right now, Mercedes refuses to fix this issue preventatively. They will only repair it AFTER the EIS module has shorted out. They are refusing to treat this as a warranty claim even though it is clearly a manufacturer defect. Please help? Thank you

We purchased this vehicle used from Mercedes-Benz of Stockton, CA in September 2021. Mercedes Benz has been unable to complete the recall after numerous attempts at the dealership and contacting customer care after 3 months. We cannot use the vehicle for our business with an open recall and Mercedes-Benz does not have a fix.

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

My husband was stopped at a stop light on Sept. 9th when the van randomly (and without provocation) shifted itself from drive into park. We called the dealership to explain the problem and ask that they look into it. We made an appointment and dropped off the vehicle yesterday. Service Department called and verbally stated that they had taken a van on a test drive and that the van had acted "normally" and that they anticipated returning the van to us with the instruction that if we experienced the problem again to contact them. I was not happy with this response as I felt that the problem was a severe safety issue and not enough had been done to investigate it. I quickly googled "mercedes going into park on its own" and found an article detailing reports of 2010 mercedes sedans going into park on their own while the driver was slowing to stop (exactly as we experienced). An accompanying official mercedes benz service department memo in the article confirmed the problem, mentioned the "auto p" feature and blamed the problem on a faulty ignition switch. I called the service department back, referenced the memo and asked if a faulty ignition switch could be to blame. The service department stated that it would be impossible because the ignition switch has changed. They stated that my husband must have taken off his seat belt and engaged the auto p feature. My husband did not unbuckle his seat belt that day. The dealership returned the van noting that they were able to duplicate the issue and engage the auto p feature by unbuckling the driver's seat belt at low speed. My husband and I tried to duplicate and engage the auto p feature ourselves by unbuckling the driver's seat belt after it was returned but were unable to do so. Interestingly, mercedes benz has recently issued a recall for driver's manuals because they acknowledge that the directions for how to engage the feature as explained in the manual are incorrect. Unbuckling will not engage auto p.
