We are sorry to hear that your last visit to our service department did not go as smooth as usual. The work done on your vehicle was a recall inspection for "Material Over Sensing and Diagnostic Module (SDM) Retaining Moisture". The vast majority of vehicles investigated under this campaign do not need parts - if they do and parts are not in stock, then parts are ordered in and in some cases require a second visit. Often parts are readily available, however in your case there was no problem with the SDM, and foam was removed from around the module as a precaution, as called for in the recall instructions. It is not possible to say for certain whether a vehicle will need parts until the inspection is complete. Either way, there is no charge to the customer. As for any miscommunications that occurred in the service drive-through, we apologize. We understand that for new visitors to our service department, the morning rush can be overwhelming, and not everybody is used to bringing in their vehicle for a service drop off in an indoor drive through. For our new guests, we will continue to make an effort to ensure they are oriented adequately, and made to feel welcome. Another way to avoid miscommunication is to have the owner of the vehicle speak to the service advisor directly. We welcome all inquiries, and your service advisor would be more than happy to assist.
