I have an appointment with my dealer this Friday afternoon so I'll see what they have to say about this situation.

I'll keep you all posted.

The factory oil that's installed from the manufacture IS NOT ester based. All they're going to do is a free oil change that is ester based, but as soon as you change your oil back to traditional dino oil, it's going to create the noise again.

will penzoil ultra fix the problem thanks

I don't think so. I have Pennzoil Platnium in mine and it is doing it. My dealer is looking at my car now since Friday...so far they don't know what is causing the noise.

I got my car back about a week ago. My dealer talked to a senior technician at Nissan Canada and Nissan USA and they said to change to ester oil and told me to drive the car for 1000 kms (625 miles) and see the result. They told me to report back to them every 250 kms (156 miles).

So far I put on about 270 kms and noticed the klonking sound doesn't seem as loud as before. I'd say about 10 to 15% quieter.

franky - what did your dealer say?

i never went to dealer..
so now your stuck paying for ester for as long as you own the car..thats crazy

The Truth Hurts

so u still getting klonking noise despite the ester oil? Even if 15% quieter, the problem is not fixed. They didn't suggest updating ECU or something like that?

pcwd

Yes, they updated the ECU. They also reset and checked the timing on the actuators. They also flushed the fuel system thinking there might be water in the gas, or wrong gas octane was used.

I just had the slow cranking TSB work done (https://www.myg37.com/forums/tsb-tec...y-upgrade.html) on my 08 G37S coupe, and I swear it fixed the klonking issue I was experiencing, so you may want to try it out.

pcwd

Thanks toastmaster.

However, now that the temperature is above freezing, my car no longer make the klonking noise. I will mention this to my service advisor the next time I see him for oil change.

Do you have the TSB number? I checked the other link you posted but did not see the TSB number as well.

Another micro-necro bump. I typically don't shut off my car and then start it right away but did so recently and noticed "the knock" which went away within 5 seconds or less. I've been able to repeat it since. Shut the fully hot car off. Count to three, restart. I get a knocking noise. Had the dealer do a synthetic oil change last Monday and I noticed the knock again today. Going to head in to the dealer early tomorrow to at least give them a head's up and see if they'll change the oil using the Nissan stuff. Mine's a 2013, 21K and change on the odometer.
