Service bulletins for the 2016 Acura MDX

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.

B17-0262018-03-13. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN. Service bulletin - American Honda is extending the warranty on the 9-speed transmission warmers to 10 years from the original date of purchase with unlimited mileage. This warranty covers vehicles where the engine coolant and ATF mix because of an internal leak in the 9-speed transmission warmer.
B17-0102018-03-13. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION. Service bulletin - Some 9-speed transmission warmers were improperly manufactured and allow the engine coolant and ATF to mix. If the fluids mix, the engine and transmission may be permanently damaged and require replacement. These vehicles previously had the transmission replaced because the transmission warmers leaked. In rare cases, these vehicles may have also overheated but because the issue was under investigation, a standard repair procedure hadn?t been developed. Further action is needed before the vehicle is completely repaired.

Service bulletin - Some 9-speed transmission warmers were improperly manufactured and allow the engine coolant and ATF to mix.

B18010G2018-03-13. Service bulletin. ENGINE; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Servicenews article - We?re getting reports of reduced engine power with the MIL on. Service techs are seeing DTC P0369 (CMP sensor circuit intermittent interruption) and signs of excessive camshaft end play.
BTS1802042018-03-12. Service bulletin. ELECTRICAL SYSTEM. Tech line summary 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.
B17-0342018-03-05. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Service bulletin - The MIL comes on with DTC P0430 (front bank catalyst system efficiency below threshold [Bank 2]). The PCM software may misinterpret sensor inputs as a deteriorated catalytic converter.

BTS1802022018-02-26. Service bulletin. STRUCTURE:BODY. Tech line summary article - debris lodged in the gap between the touch screen and the bezel.
