DIGItonium, As a matter of fact I did. The car would hesitate (for probably less than a second) if I hit the gas to accelerate quickly, I'd almost call it a sputter. I've been reading several threads regarding the high oil temp issue - and kind of attributed the lack of power/hesitation to that issue. My oil temperature seems to hover (with normal driving) in the 230 range. I do feel as though that sputtering/hesitation feeling is gone after this most recent visit. I'm not sure if the electronic device replacement (IPDM) solved that issue? But -- it does "seem" a little peppier than before. the mechanic that worked on my car said Nissan Corporate told him to change the IPDM part -- he said he wouldn't have known to replace it. I've been doing a little Google'ing about that part. It seems as though it's a known issue with other Nissan vehicles (mostly the truck & SUV line-up). I also noticed that AK370 posted a TSB about that part also -- if you do a search you'll find his post. You having some issues?

Oh -- and also, the mechanic seemed a little frustrated with the plastic fuel line? He was ranting about a clamp or something causing a piece of plastic mashing (causing a crack) which caused the fuel to start leaking after he replaced the fuel pump (see my previous comment about the car wreaking of gas above). The dealer is obviously shaky about the "repair" to my problem -- they do NOT seem real confident that they've completely solved this issue. I don't think they have either...just a feeling :)

So in short -- YES I did have fuel pressure problems. They replaced the fuel pump originally because they said I was losing fuel pressure when the car just sat.

Thanks, Bob! I got a call back this afternoon and the tech was told that it was oil temperature. It doesn't make sense for daily driving conditions that the ECM would start cutting power when the temps are above 200F. Mine typically hovers around 220F. With cooler temps, 200F on average. :dunno: Hopefully more complaints roll in so Nissan can do something about it besides blame it on oil temperature especially when it's just casual driving.

Damn, i now have the same issue. The car has been sitting at my condo basement for 4 weeks (work on an offshore rig). Before i leave, gave her a good fuel fill up till full with Shell V Power. When i came back 2 days ago, the car start straight away after the push, no problem at all. Today after few good runs on highway (temp normal), i went for a movie with my GF ~ 3hrs. Came to my car at valet service and it takes solid 3 cranks and a noticeable clunk before it start. Got back home, shut off the engine and try to give it a start, same 3 cranks and a clunk then vrrrrooom. Will send the car to Nissan service center tomorrow.

There's your problem...

To the OP, does the car stumble a little when it does start after cranking for a few seconds? To me it sounds like a fuel issue. Either an air leak is causing you to lose fuel pressure (worn or cracked seals in the fuel system such as injector o-rings) OR an injector(s) is leaking. If you have an injector leak, they will start to leak as soon as you shut the vehicle off. If you start the vehicle back up as soon as you shut it off, you shouldn't have any cranking issues, but leaving it for a couple hours will cause the injectors to slightly flood the chamber and thus the hard starts. Leaving it overnight will "dry up" the flood and so no hard starting issues.

Pressure test the fuel system and see if there is any fuel pressure loss.

Old thread I know.

So no one has found the definitive solution to this problem yet? I have been having the same issue since 10,000 miles, and I am now at 22,000. Again, it always starts fine on the first start of the day, and the car runs fine otherwise, but if I let it sit for 2-3 hours after the car is warmed up and then try and start it, i get the horrible noise at startup and its a very hard start. Just like the video! Please! someone must have the answer to this!!!

Still happening
 

Still have the rough start. Nissan dealer has now replaced the battery - says it's a charging problem. Completely and thoroughly clueless. They also installed a monitoring computer and had me drive the car for 10 days. They have since removed it and sent it to Nissan. I have been communicating with Nissan Consumer Affairs - total waste of time. They do not care. My solution is to complete my lease (1 more year) and buy a Cayman. Nissan has lost me as a customer for life.

Thanks for the replies b, I feel your pain. I can't believe more people havent reported this issue and Nissan is not aware of the fix for it. Please report back to this thread if they find the solution and I will do the same. Unfortunately I am not in a lease. I will have a hard time selling a sports car that sounds like a 25 year old beater when it starts. :shakes head:

I have been calling every dealer in the state to see if someone has encounterd this problem and found a solution and nobody has. This is so sad. I love my car besides this annoying problem :(

Good Luck
 

This has been the most frustrating experience I've ever been through (car wise) in my life. For anyone that ever has to deal with Nissan Consumer Affairs - be prepared for a whirlwind of B.S., false promises, no communication and tons of red-tape and frustration. My "file" has been passed on to 5 different Consumer Affairs Specialists (that title is a joke) - each time having to run through the details of the "issue" I've been experiencing. 23 pages and counting. If it weren't so frustrating - it would be comical. They take down your information and hope you just go away I think - they try to frustrate you to the point where you just give-up. I have made a formal request that Nissan buy back the car - that in itself will probably take the year that I have left on my lease. Then I'm finished with Nissan for life!! Good luck to the rest of you -- you're going to need it if you have any issues :)

For what it's worth, here is a video of my hard start problem:

Djpheer,

Wow - identical issue. I wonder what the similarities are between our cars? Build date etc. How long have you been experiencing this? Has your dealers service department tried troubleshooting this for you yet? Keep me posted.

Well, its a 2009 base model, 6MT, and I have 23,000 miles on the car right now and it's been doing it since 10,000. I haven't gone to the dealer yet because the other people I have seen with the problem haven't gotten it fixed quickly (or at all) and I can't afford to be without my car for a long period of time since it's my daily driver. I will bring it in sometime before the warranty expires though for sure. The car runs fine otherwise, pulls hard, etc. Just this one annoying issue.

Did the dealer change out the Crankshaft positioning
sensor as a potential fix yet? Someone mentioned that in this thread and the more I read about it and what it does on cars in general, it does seem like a possible culprit.
