B18070C2018-08-06. Service bulletin. ENGINE; ELECTRICAL SYSTEM. Servicenews article - Until recently, Tech Line had only two categories for auto idle stop system issues. That made it hard for our engineering staff to understand what was specifically inhibiting the system. To help with this, Tech Line has added more categories to match what's listed in the service information. As a result, when calling them for an auto idle stop issue, you must now send a snapshot. Tech Line needs it for troubleshooting and won't be able to help unless you do.

And since that gap widens and narrows with cabin temperature, this issue can be intermittent, especially in cold weather.
