This bulletin applies to 2016-2019 Acura MDX, 2017-2019 MDX Sport Hybrid and 2018-2019 TLX vehicles. The vehicle may exhibit several of the following:

- Multiple injectors are on

- No communication with the i-HDS

- The option fuse (7.5A) is blown (on MDX: Fuse E21; on TLX, Fuse B7)

- The MDX engine may be difficult to shut off

- The TLX transmission will not shift from Park

Under certain conditions, the battery fan motor draws excessive current, causing the option fuse to blow. If the option fuse is blown, replace the blower fan motor and fuse.
