I have and 04 Track model.
My Service engine light went on two weeks ago. No noticable difference in performance. Went to the dealer, it was diagnosed as a random missfire.
Drove home, drove to work, light went on again after I started the car after work. Brought the car back to the dealer this morning...
Multiple missfires, they tried new plugs. Tried swapping out something (sorry not sure what) Now they tell me they want to replace 3 fuel injectors and the cost would be about $945 plus tax.
Do they really know whats wrong with my car? How can 3 injectors go bad without something else being wrong?
I will definitly write a letter to Nissan when I have a bill to mail them.
Anyone have any similar experience or have any advice on my next course of action?
Thanks!
FL Drifter.

 

take it somewhere else

 

Too late for that..any other suggestions.

 

lol. good luck. my car has been like that for 25k miles. multi cyl mis fire... i finally gave up on it

gas milage hasnt depleted (400 miles to the tank still) and seems to run fine... but if you ever find anything out PLEASE PM ME AND LET ME KNOW!

 

didn't someone else have this problem and found out it was one of their coil packs.

 

dont know. but i have had o2's, plugs, injectors, coils and maf replaced and still got it


cant figure it out

 

Why is it costing you anything - it should be under warranty. From the 2004 Warranty book:

POWERTRAIN COVERAGE
• The Powertrain coverage period is 60 months or 60,000
miles, whichever comes first.
• This warranty covers any repairs needed to correct
defects in materials or workmanship.
• Powertrain coverage applies to components listed below,
supplied by Nissan except for those items listed
under the caption “WHAT IS NOT COVERED”.
ENGINE
Cylinder heads and block and all internal parts, rocker
covers and oil pan, valve train and front cover, timing chain
and tensioner, oil pump, water pump and fuel pump, fuel
injectors, intake and exhaust manifolds and supercharger,
flywheel, seals, and gaskets.

It sounds like they don't know what's wrong and they're trying to screw you.

 

powertrain consists of engine, trans, axles, and driveshaft.

nothing that bolts to the engine other than the trans is part of the powertrain

 

John,

The section that I posted is the "Powertrain Warranty". Below it are the sub-categories for Engine, Transmission and Transaxel then Drivetrain. Those sections list what is covered on each of the powertrain items.

Here is the complete section:

POWERTRAIN COVERAGE
• The Powertrain coverage period is 60 months or 60,000
miles, whichever comes first.
• This warranty covers any repairs needed to correct
defects in materials or workmanship.
• Powertrain coverage applies to components listed below,
supplied by Nissan except for those items listed
under the caption “WHAT IS NOT COVERED”.It on pages 4 and 5 of the 2004 Warranty book.

 

i understand....

but where in what you poster does it show coils, plugs, maf or anything else except injectors?

unless all you are refering to is injectors.

but injectors arent what is causing his multi cylinder misfire (atleast im pretty certain)

 

^^ But if they charged FLDrifter $945 for the injectors that would suck! and would be enough $ to get the other items and then some! The MAFS I would think is part of the emissions and would also be covered, I could be wrong thought...

 

That's most disturbing. What actually detects the misfire? The knock sensor(s)? That seems a cheaper way to go first than MAF, Coil Packs and Injectors.

 

Hey guys,
thanks for your input. I should be able to pick up my Z on Wed or Thursday. I will pull the warranty manual out of the car when I get there and point to the page your talking about.
Right now I just want my car back and will write Nissan a letter with my bill.
(My dad had a problem with the 02 senesors in his 02 Tundra which Toyota ended up reimbursing him for).
My understanding of engines is basic, I understand the difference between two strokes and 4 strokes, and many of the parts, but I am not sure abou the coil packs. If am not mistaken they tried swapping coil packs and that didnt change which cylinder was missfiring.
I will definitly keep you all updated with both the mechanical problem, and the financial outcome.
I want my Z back, I miss it already.

 

Thanks DavesZ#3
I have printed out the section of the warranty you quoted and will put that right in their faces.
I have nissans consumer affairs number and will dial immedialty if the start givning me a hard time: 800-nissan5

Thanks, until I see the service details/bill I wont know for sure what they did to my car, but I will share with you ASAP.

 

OK i'm on my way to the dealer now, they just called and said my car is ready. The quoted me $1050 on the phone. I will walk in there with warranty in hand and I hope to walk out of there paying next to nothing. Wish me luck.

 

Give 'em hell!!!!

 

Thanks for all your input.
All work was fully covered under warranty, after I pointed out that fuel injectors fall under the Drivetrain Warranty.
Invoice listes the following:
Replaced 3 bank 1 fuel injectors.

 

please let me know if your light comes back on in the next couple weeks....

 

Sounds like your dealership was trying to double-dip, get paid from you and don't they also get paid from Nissan to do warranty service?

In any case, they should've known it was under warranty, you shouldn't have to point it out. I would never go near there again.
