NHTSA Complaint #11442307 — 2019 MERCEDES-BENZ SPRINTER 3500

The powertrain controller and the ignition switch module found to have water corrosion, due to moisture dripping from window condensation. This is a well-known and documented engineering/design flaw of 2019 and newer Sprinters, with the newer electronics located where they are highly susceptible to water damage from window condensation. This results in a sudden "kill" leaving passengers suddenly, unexpectedly, and without prior warning stranded, creating a serious safety issue. Possibly becoming stranded suddenly, without warning in an extreme cold or hot outdoor temperature, and in areas without cell phone reception is a serious safety concern. A tow is necessary to an authorized Mercedes Service Center. Our safety has unknowingly been put at risk, had this happened in an area of no cell reception and adverse weather conditions. Though well documented and known by Mercedes (Sprinter Source.com and Service Departments) this issue has not been escalated to a Recall level. There were no warning lamps, messages or other symptoms of the problem prior to the failure. We have since learned that this issue is not a matter of 'if it happens' but WHEN it will occur. Yet, warranty coverage is not available until until one becomes suddenly stuck and stranded with an inoperative Sprinter. Yes--this should be a Recall! Wilsonville, Oregon Mercedes Service Center says the above condition is well-known, and Mercedes has recommended a fix with a Mercedes plastic bag covering and a relocation of vulnerable electronics. Our corroded electronics were inspected and confirmed by above Wilsonville Service, and our Sprinter is currently awaiting parts for replacement, all under warranty.
