Took the 2007 Altima 2.5 in for service today with 1,500 miles. Engine has loud rattle when starting cold, and louder when shifting into drive or reverse as the idle kicks down a few hundred rpm. I sense that the engine oil has settled over a period of time not running. Further, I believe the internal engine parts do not get the oil lubercation until fully warmed up. Then the loud rattle goes away. More noticeable as we get into the cooler/colder Fall days.
Nissan dealer is calling the "hot line" to see what the problem and/or fix might be.
Has anyone experienced this loud rattling noise during engine warmup?
