Had mine done under drivetrain warranty 2 months ago. I called and asked about the recall, they said it has to be redone to avoid lawsuits and to make sure the parts are more current.

Good to know this, thanks BlackCat81!

Actually, if I recall, something does change when I connect the cable and read it...it says "UpRev" somewhere, not sure if it's the part number or somewhere else. Will have to check.

Dropped mine off this morning. Have a nice Q70L for loaner. Sure wished it was V8 version and they so need a Sport model on the Q70L, it would be my next car if they did it.

Looks like the damage can even happen to a low mileage car...

Picked up my car today, according to the service log:

Timing chains were stretched and one oil jet was damaged.

I only have 38K on the odometer, I was pretty surprised to see damage had already taken place. I definitely recommend everyone get this done right away.

I did confirm, as I was in my UpRev software tonight, that the ECU part number looks to be changed.

New question Steve...will I get beef if I leave my HPS intake tubes installed when I bring it in or should I be on the safe side and put the stock intake stuff back before I drop it off? I plan to completely remove the UpRev map too.

I was wondering if the recall would apply to owners of M56's who purchased used. In my case, I'm the 3rd owner.
Thanks for the Great Info!

This is great info, I plan on buying a used one, but not from an official Infiniti dealer unfortunately. Would the repair costs for all of the:

- timing chain (ID: P6305)
o ITB11-047b (Bluetooth Sound Quality)
o ITB12-021B (for M37 ECU/TCU software but I seem to have some of the same lag and hesitation)
o ITB11-046a (Call Waiting Navigation Update)
o ITB12-010a/ITB15-017 (Fuel Rail Re-torque)
o ITB10-040 (Air/Fuel Ratio Sensor)

come out of my own pocket?

Anything that is a recall is covered by the dealer. Not sure if all of those have been found to be actual recalls yet or not.

I don't have the M56, but I'm curious is this only affecting certain VIN numbers on the 56? or is it everyone one on the road

As far as I can tell it is for 2011-13 M56 models and probably the same year range of QX80. The 2014+ Q70 (with the 5.6 obviously) do not seem to be included...yet.

Yea I was just reading the post others are reporting after the repair, the startup noise is still there so that must be normal noise from that video. So how do you know the chain is bad on your car? is there a code at some point.

It's based on VIN...they must have determined that a particular period of manufacturing is when the issue existed. On the QX56, it was also a whine when the car was running (long after the normal whine of the cold loop goes away).

Would a stretched chain cause any lapse in performance?

It seems my car has much more power and runs a lot smoother than it did before the recall work.

I don't believe so. The dealer disconnects the battery while replacing the chains which may reset the ECU and transmission programming. This may be why you feel your car has more power.

I drive my car in sport and manual mode and find the car performing the same as before the chains were replaced. I was told the original chains were not stretched but I only have
27,000 km on the odometer.

In my case, yes it will affect performance big time. My chain (B2 side) was stretched to the point where the transmission threw a P0024 exhaust valve timing code. I couldn't accelerate to pass anyone, but if I pressed the pedal slowly I could build up speed. Same issue at a stop light. If I tried to accelerate quickly, it would bog down.

I have a 2012 M56x. Recently, it went into "limp mode". I had to have it towed to a respected shop, but not a dealership (live 150 miles away from the closest one). They changed the oil and cleaned the throttle body. It cured it for a while, but has reoccurred numerous times. I have to disconnect the battery to reset the computer. It works for a few days, then happens again. I have an appointment with the dealership on Friday to have the timing chain replaced. Could this be the underlying problem causing my frustrations?

Without knowing if any codes were in the system, it's hard to say. Limp mode is an all encompassing protection protocol of sorts and can happen for 100 different reasons.

Welcome to the forum, BTW.

No it definitely wasn't because of the ECU reset... I have reset the ECU when flashing new tunes numerous times and am very familiar with the feel of the car after a reset; plus I have already put a good 150 miles on it since the reset. Maybe its the HPS intake tubes :p (That was sarcasm)

Did the check engine light come on? What was the diagnostic trouble code they got from the car? This code will generally point you in the direction of the cause of your issue(s). It is most likely what made them look to the throttle body as well.

You should probably start a new thread with this information so that more people will view it and possibly offer insight into the cause.

Different engine block. Different timing parts. Don't worry about it.

The M37 does not have enough HP to stretch the chains, don't worry. :chuckle:

I've done one with 22k. I have one I'm doing next week with 37k on it that's noisy.
