Service bulletins for the 2016 Acura TLX

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

B18070E2018-08-06. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Servicenews article - We're currently looking into a no-start issue requiring 12-volt battery replacement. To fully understand what's causing this issue, we need to collect failed batteries from vehicles that meet these criteria.
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.
