Hey guys. I understand I own a QX 50 and am in the G37 forum however my problem is very similar. We do share the same engine. My 2017 has a noticeable knocking noise after only 50 miles on the odometer. I’ll admit it is no where as noticeable as on this thread but can be heard at idle only after Car warms up. It will then go away once driven for 20 minutes or so. Car now has 13,000 miles and noise still shows up once warmed up but is gone when driven a number of miles. Dealer claims it is the normal VVEL noise. So far I’m living with it as I have 5 1/2 years left on factory drive train and engine warranty. Neither of my G35s with 11 years of ownership had any noises. I’m not happy but at least the noise always goes away after about 20 minutes if driving. I’m just concerned on what if any damage is occurring during the time it does make noise.
