Looks like some '02 & '03 TL/CL 3.2 and MDX are affected by it. Make
sure to check out the VIN range to see if your vehicle needs a repair.

What caught my eyes about this though was the last sentence in the
first paragraph. The paragraph states,
"Product Update: The timing belt tensioner is filled with oil to
dampen oscillation. Due to a manufacturing problem, the tensioner oil
can leak. If enough oil is lost, the timing belt loosens and cause
engine noise."

Anyone know what kind of noise this can be? What the noise might
sound like? Thanks.
