This bulletin applies to 2014-2017 Acura MDX and 2015-2017 TLX vehicles equipped with SH-AWD. If you notice what appears to be a rear differential axle seal or pinion seal leak, the actual culprit may be something loose or damaged above it.
A loose or damaged fluid pressure sensor will drip rear differential fluid onto the axle seal. A loose fluid pressure check port will drip fluid onto the pinion seal. Before considering a rear differential replacement, check these areas closely.
