My perfectly maintained Avalon XLS has low mileage( 49,000 miles). Its engine has been extremely quiet, so far. But in the last couple of weeks, I noticed that when I accelerate while doing low speed (about 45 mph, at 1800 rpm), I started hearing a muffled roaring noise. It is hard to pinpoint the source or direction of the noise, whether it comes from the front or from underneath. Cursory inspection shows the tail pipe and muffler to be in perfect shape. What could be the cause of the noise ? I certainly would appreciate some suggestions. Thanks.
