Aren't the Cats considered a Emission part? If so then the warranty is 8 years 80k.

Specified major emission control components
are covered for the first 8 years or 80,000 miles.

CARBs states have longer warranty, I don't think Texas is a CARB state

Yeah. Since CARB stands for California Air Resources Board :tiphat:

You are correct, thanks for the correction - used to be 3/50,000, but was increased to 8/80,000.

Here is the verbiage straight from the EPA notice that you posted:

There are three specified major emission control components,
covered for the first 8 years or 80,000 miles of vehicle use on 1995
and newer vehicles:

* Catalytic converters.

* The electronic emissions control unit or computer (ECU).

* The onboard emissions diagnostic device or computer (OBD).

I've fixed my post.

OP, I think this is a case of an "engineer" talking out of his butt, making things seem more complicated, just to validate his existence. lol

Here are the gory details:

• Federal Emissions Warranty – Under the Federal Emissions Warranty, all emissions related parts are covered for 2 years or 24,000 miles*, with the catalytic converter, onboard emissions diagnostic device or computer (OBD), and engine control unit (the ECU or computer) covered for 8 years or 80,000 miles*. These Federal Emissions Warranty provisions cover light-duty vehicles up to 8500 pounds Gross Vehicle Weight Rating (GVWR).

• California Emissions Warranty – Under the California Emissions Warranty, vehicles certified for sale in California, and those states (e.g., Vermont) that have adopted California Emissions Standards by law, have additional coverage beyond that required under Federal law. Under the California Emissions Warranty, all emissions related parts are covered for 3 years or 50,000 miles*, and a vehicle-specific list of more expensive emissions related parts is covered for 7 years or 70,000 miles*. In addition, the 8 year or 80,000 mile* coverage for the catalytic converter, onboard emissions diagnostic device, and engine control unit required by Federal law also applies. Also, some 2003 and later models, certified as California Partial Zero Emission Vehicles (PZEV), have 15 year or 150,000 mile* emissions warranties essentially covering any component that causes the Check Engine Light to illuminate. These California Emissions Warranty provisions cover vehicles up to 14,000 pounds GVWR.

*Whichever comes first

However, be aware that some manufacturers have voluntarily extended their emissions control warranties for certain models and certain parts to 14- or 15-years and 150,000 miles (whichever comes first).

OP, how did you break in your last two engines? When did you perform your oil changes and what oil did you use?

Seb

He took "break" too literally during break-in.

The first engine never needed an oil change as it got replaced at 2900 miles, though you could argue that adding six quarts of oil might count as an oil change. Break in was boring by the book with the 4,000 rpm limit that could have gotten to 4500 via SRM, operator mistake, or dealer test drive (higher still?).

New engine is still under break in, with no SRM mistakes only a couple momentary 4200 rpm operator errors. Thus far, no oil added either.

It is so very difficult to not drive the car all out, as I did for weeks. Then go back to break in.

Are you sure you spoke with a Nissan Engineer? If so, are you sure he knew anything about the VQ37 and wasn't an Engineer in the floor mat division?

:bowrofl::bowrofl:

first engine replaced at 2900 i'd call that a failure.

Op,
I feel your pain...:shakes head:
It's sad to hear that you are going through this mess and I hope everything works out with the new motor.

If I may ask, what year is your 370z?
-09?

Any 2010's with similar problems?

I think the Nissan TSB covering new short blocks for oil consumption includes 370Zs made through May of 2010.

Please tell me where I can find the TSB on oil consumption, my 09 is in the shop as we speak. It went into limp mode the other morning and the first thing I checked was the oil and it was 3 quarts low and I only have 2500 miles on it. I did mention this to the tech at Nissan and he also felt that it was excessive. I will find out more tomorrow.
