In my experience, few of the MB service providers submit repair data to a centralized data base. I tried to get some investigative support from a service dept. in Buffalo and they saw just one of four prior service visits. The service advisor explained that there is a separate step involved in submitting data up the chain so many just skip this step or maybe do this on a slow day...there is no profit in this step.MB likely has records on everything that MB shops have done to your RV. Make them pay.
This is not really surprising - in a mass market of consumer goods, shops get their highest profit by following the corporate procedure. Get enough information to comply with the level of proof required to declare a component "bad", swap the component, and be done. Only a few shops (not normally dealerships) will do extensive tear down and testing - no profit. Some components are shipped back to HQ to get a teardown and testing, especially high warranty failure items, but that is normally focused on ensuring owners and dealers aren't gaming the warranty system - part of corporate warranty cost containment. If the warranty item is actually failing at a high rate, information will flow from the warranty managers back to engineering. Depending on the levels of warranty costs, engineering may be tasked to actually diagnose and perhaps do a redesign. Organizations such as the NHTSA can do a little more to force the issue - if they find that it is widespread enough and has a significant safety impact.The service advisor stated their policy and shop practice was simply respond to the code list, replace as needed and reset. There is no procedure, no billing code or authorization in their service documents to assess the system and diagnose why a part fails.
Dealer called today and said based on VIN recall is still Pending and until it goes Active in their system they cannot replace the sensors.Ours is scheduled at a local dealer Monday for; rear wheel speed sensors replacement, MBUSA CAMPAIGN NUMBER 2021020026. We will post anything we learn after that unless they don't have the new sensors in stock yet.
I think that is probably what the data shows - probably lots more rears and worse symptoms on the rear for a select population. So the rears on upfitted and RV get the recall and everyone in the year grouping gets the 10 year warranty extension.Why do you think the MB Sprinter recall only covers rear wheels? Don't front wheel sensors fail also?
Well, B-vans have standard rear wheel wells and, at least in my case, they are not immune from this issue. I suspect that the rears are more susceptible to moisture damage due to increased exposure to spray from the front wheels. It is also possible that long periods of sitting may help make RVs more vulnerable.The recall information on NHTSA website mentioned moisture as a cause of premature failure . Recall is only on RVs. Could it be that lack of a full wheel well on RVs allows more moisture to seep into sensor? MB logic being the front wheels have the standard sprinter wheel well and they do not have a recall able issue with other non RV sprinters . This is my theory.
