THE FOLLOWING HAS BEEN SENT TO MERCEDES CORPORATE CUSTOMER SERVICE All of the following has started happening since an exhaust recall was done by Mercedes. In September 2022, we were driving cross country to Denver Colorado and enough codes piled up in the background that we went into limp mode in the middle of 70 MPH highway traffic. This happened without warning and was an extreme safety concern. But I was lucky to be near an exit and already in the right lane. I reset these codes and finished going to Denver the next day. The two Sprinter dealers in Denver were backlogged several weeks; so we spent over $600 trying to troubleshoot the issues with Colorado Fleetworks, a qualified Sprinter specialist. He checked codes too; ran other diagnostics; replaced the fuel filter and air filter even though they had been done only 10,000 miles earlier; and performed a forced DPF regeneration. He also replaced the DPF pressure sensor. This work did not help change the daily multiple code problems. We had to reset them every day coming back from our trip. When we returned home we took it to the dealer. They confirmed the codes, reset them, and test drove it 25 miles. Since codes didn't return, they said, "There is nothing we can do if we don't witness active codes." I said, "How active do they have to be? I will have codes in the next 20 to 30 miles like I do every day I drive it." These never happened in the 6 years prior to the recall wok. Either the programming is confused, some of the new sensors are faulty, or something. A totally separate problem is the faulty factory crimps on the connector of the rail pressure sensor. This is a known defect; and we've had the exact same symptoms and code as noted in Xentry TSB MC-10135520-9999. The engine has actually cut off when turning into traffic a few times. This is an extreme safety concern.

The Office of Defects Investigation (ODI) analyzed complaint data provided by Daimler Vans USA, LLC (Daimler) as well as complaints submitted to ODI from consumers to identify incidents related to Rear Wheel Speed Sensors (RWSS) failures. ODI's analysis identified 6,710 incidents of RWSS failure (unique VINs) in MY 2012-2018 Mercedes- Benz and Freightliner Sprinter vehicles upfitted to campers or recreational vehicles (RVs) representing 81 percent of all Sprinter RWSS reports. Complaint and warranty analysis indicated that the majority of incidents (approximately 99%) were related to RWSS moisture intrusion condition in the Sprinter 3500 5-ton variant, which accounts for 98 percent of upfit campers, where moisture build-up and crystal dendrite formation develop in parked RVs and lead to sensor failures. According to the Daimler Information Request (IR) response, if the wheel speed information is detected as implausible by the Electronic Stability Program (ESP) control unit, the ESP system enters a failsafe mode where:-Driver torque requests are no longer accepted;-Cruise control, if used, would be deactivated; -The ESP/ABS system shuts off; and -Multiple warning lamps and messages advise the operator to take the vehicle to the workshop. While the majority of reports involved only ABS and/or ESP warning lights and messages on the instrument cluster due to faulty sensor signals triggering a failsafe mode, some reports cited intermittent sensor failures resulting in increased vehicle speed while in cruise control and degraded ABS or ESP. Degraded ESP functionality may impact driving stability of the 5-ton vehicle.On Feb 3, 2021, following discussion with ODI, Daimler submitted a Defect Information Report (DIR) to NHTSA describing a defect in the RWSS disabling the ESP control unit functions in approximately 48,667 MY 2012 through 2018 Mercedes-Benz and Freightliner Sprinter 3500 vehicles manufactured from Jan 4, 2012 through Oct 25, 2018 (Recall 21V-042). In its DIR, Daimler indicated that RWSS sensor failures are prevalent in camper vans due to sustained periods of non-use, during which time the moisture may not dry out, remaining inside the plastic housing package. If the moisture within the RWSS dries and the RWSS returns to normal operation, the failsafe mode and the warning lights will disappear at the next ignition cycle, but the sensor fault remains stored within the ESP control unit and can be accessed through a diagnostic evaluation. ODI will continue to monitor field experience in Sprinter non-RVs and Sprinter 2500 RVs 3-ton and 3.5-ton variants (approximately 626 vehicles).Daimler will notify owners of the recalled vehicles and advise them to take their vehicle to a Mercedes-Benz or Freightliner Sprinter dealer, who will replace the RWSS with a repackaged sensor with high robustness against moisture intrusion. Daimler began notifying dealers and owners in Feb 2021. This Preliminary Evaluation is closed.The ODI reports cited above can be reviewed at NHTSA.gov under the following ID numbers:11352380 11351299 11350521 11348969 11342776 11342464 11341988 11341151 11340388 11338230 11337921 11331832 11331829 11331476 11331427 11331066 11328671 11325768 11325693 11322814 11322346 11320295 11319376 11317336 11311647 11310621 11308318 11254223 11253828 11252220 11196530 11194330 11164250 11145019 11141273 11139000 11138785 11124129 11094122 11394837 11390889 11390039 11389262 11387883 11387713 11386418 11383887 11383866 11382947 11377384 11376615 11376973 11375781 11375403 11374997 11374151 11373892 11373111 11366293 11365920 11365594 11365355 11365194 11364253 11364346 11363990 11363787 11362948 113629
