Power steering units on Acura/Honda models can leak and make a growling sound when temperatures drop below 60 degrees F, leading to noise, fluid foaming and leakage, and power steering problems once the fluid level drops too low. This often leads to a P/S pump replacements and sometimes more. The actual cause is often a $1 gasket on the P/S intake hose. This is a common problem due to a gasket that - as it ages - shrinks too much when it is cold. Buy the part at the dealer, use offset wrenches to reach the two bolts holding on the flange, remove and replace the gasket. It's a 5 minute job if you can get the bolts off. At least on the 2004 MDX offset wrenches are necessary.
