Lemon?

jruiz370z · 01-02-2012, 01:30 PM

Got my Z in march 2011, ever since the check engine light comes on pretty much for no reason. I literally took the car to the dealership more then 7 times. And they cant not figure out why it's doing that. The car is pulling a Multiple cyclinder misfire code. But the car isn't actually doing that. So I take it to the dealership and they really dont know but the car is still under warranty. but its getting close to being out of warranty and they haven't figured it out yet. Last they had my car in for a week, and had a Nissan engineer working on the car. they said they changed my ECM, but engine light still came on after that. frustrated. dont know what to do!?!?????

Hmmmm. Prior to putting any mods on my car I was getting a check engine light throwing a random misfire code. The day I had it scheduled to go into the dealership I was driving there and the light went off like a mile from the place. I wanted to have it checked out before I started modding the car but couldnt wait any longer for it to show up again. Ended up doin my mods, which included ECU tune via UpRev and never saw the code again. Im interested as to what was causing this myself.

yea i'm not sure, they cant figure it out. I mean had a multiple cyclinder misfire happen in my 350z and you can definately tell. This engine light only comes on at start up. never as i'm driving.

Check the Lemon Laws of your State because every one is different. Some times it takes a Lawyer to deal with the situation too. GL

TreeSemdyZee · 01-02-2012, 03:50 PM

How do you know that it isn't misfiring? You don't necessarily feel a misfire.

jruiz370z · 01-02-2012, 04:15 PM

Because they have checked all the cyclinders and supposely have ran tests on the injectors and what not. Dealership is saying the car isn't misfiring. Nissan engineer came out and put a new ECM. Still came on.

Was your Z purchased new in March of 2011? Or did you buy it used? I don't know the rules for your state, but I don't believe that lemon laws usually apply to used cars. I only bring it up because your sig says your Z is a 2009.

Here in Illinois, for instance, you must be the original owner and have documented proof that the dealer has attempted & failed to correct a specific problem more than 4 times OR that the car has been out-of-service for more than 30 calendar days within the first 12 months or 12,000 miles of ownership.

Check your state lemon laws. They're easily found on Google. They're also printed in your maintenance booklet that came with the Z (by law). If you think you qualify, then contact an attorney in your area that specializes in lemon laws. He/She will be able to offer advice on how you can proceed.

My CEL went off and I needed a new MAFS. The light went on two weeks later and off two weeks after that. Very annoying.

So what did you do after that happened? Thats whats happening with mine.

SPOHN · 01-02-2012, 06:34 PM

Did they change the plugs or coil packs?

jruiz370z · 01-03-2012, 08:42 AM

no i dont think they have changed the coil packs or plugs!

theDreamer · 01-02-2012, 06:36 PM

Do you have another dealership you can stop by and have them look it over?

I guess I could try another dealership!

Sounds electrical. First suspects would be forward O2 sensors, coilpacks seem less likely unless they were damaged by water penetration (unlikely unless you power wash the engine bay).
