Humming/groaning sound
Finally got the Tech to acknowledge the Humming/Groaning from the Engine as I sat behind
the wheel at my 5000 mile service visit. His response was that the sound we were hearing
( at start-up) was "NORMAL"
Of course, dumb old me, said " How's come it goes away after 5-10 miles of driving" ?
(NO response other than NORMAL)
The RX drives and sounds fine after that mileage, but many times my destination is less,
and I feel like I am driving a reject.
This has persisted since new, @ frigid and high temps; as we approach 7500 miles.
Has any one else experienced anything similar where engine sound varies in pitch when
acceleration increases the RPM's ???
