I just went in again to talk to my service rep manager to continue pressing them to fix the issue. I need some help from the forum:
The service manager needs other case examples of this problem to pull up so he can show examples to the regional rep who is coming in town on Tuesday. He needs the last 7 numbers of the VIN from other Carbon build up D's to pull up cases from their database. Anyone that's had Carbon buildup please PM or email the last 7 digits of the VIN for me to compile a case list. email@example.com In return I will put together a comprehensive case for others to use in the future and for a group letter.
Thanks in advance.
