On the 2001-2013 Acura MDX, first- and second-gen MDX power-steering high-pressure hose deteriorates and cracks at the metal-to-rubber crimp, weeping Honda PSF onto the subframe and causing whine, low-fluid warnings, and eventually pump damage. Internally, the rack develops 'morning sickness' - stiff steering when cold that loosens once warm - from worn input-shaft Teflon seals. Note: morning-sickness/rack failure is best-documented on 2003-2013 (Gen 1.5 and Gen 2); high-pressure hose failure spans 2001-2013.

Common Symptoms

PSF puddle under right side of engine
Whining noise on cold-start when turning wheel
Stiff steering when cold ('morning sickness')
Low PSF reservoir level
Reddish oil residue on subframe

How to Fix

Replace high-pressure hose with OEM (~$150 part, ~3 hrs labor; subframe must be lowered). Use ONLY Honda PSF - no universal/ATF. For morning sickness, replace the steering rack with a reman unit; do not band-aid with stop-leak additives.

Typical repair cost:$350 - $1,800
