Anybody having engine problems yet or has heard of??

[EvolutionVI]

To make it short,my 2 month old EU-GTR has a engine failure.....happend after a 300km/h+ run on the german autobahn,had no problems or noises with the engine even on the 2km after the full throttle run,then i was going on the exit of the autobahn and stopped the car on the next crossroad and had the car idling,after around 5 sec standing there the car developed a hard,loud knocking sound from one second to the other,really not a typical enginefailure like you would expect from lets say a conrod failure or a melted piston,it sounded more like a total loss of oilpressure from one to the next second.

There is absolutly no damage to the pistons,head or somewhere in that area,no smoke,nothing,engine ran fine at idle,but rattled like hell.

Nissan is not covering my failure due to the fact that i did not meet their warranty rules(noone will,they find excuses everywhere),so i have to chase my dealer now(after a 4 weeks wait till they told me my warranty is finally voided) to put a new engine on basis of the european buyers rights in my nearly new car.......here in Germany there is another GTR which has i believe the same failure....its Nissan´s own press car,knowing that it was with a enginefailure in Hamburg at the HPC and it had the same symptoms after the same full throttle driving...but they dont say anything about it,they are more friends of hiding under their warranty rules instead of doing a good customerservice...

I got a lot of info´s about the press car and on even more interesting things,which i cant say now as i can´t back it up....but im trying to get more data together,so if anyone knows a EU GTR from the first batch of cars(those with the chassinumbers till lets say JN1GANR35U0100500) that have arrived in europe,please keep me updated,i really appriciate it

Best regards

how many miles have you done ?

you been on nagtroc ?

[EvolutionVI]

6500km....most of it just normal autobahn driving,only very little racetrackuse....car was cobb´d,stage * 97oktan,driven with 100oktan fuel,but this doesn´t make a bottomend failure....its a pure mechanic failure and can happen to any GTR out there too,so it would be interesting to know more about other cars that have problems,but we here in germany maybe have the hardest streets for these cars,the german Autobahn,so its not sure my car would have not had a failure in lets say america,where you cant normaly do 300km/h + daily

Having just read your thread ..

Tested my GTR from 0-300km/h yesterday......oh yeah,its fast

And I quote "If i can chose between a "slow" GTR with warranty(where they charge you a lot of money for keeping the warranty) or a "fast" GTR without warranty(which you can service by a specialist for a lot less and maybe better) then i dont have to think twice.....grab the phone and if youre from UK call Ben for the Cobb AP....if youre from germany...call me"

And seeing how the HPC is treating you, have you changed your opinion on the Cobb AP (and its affect on your warranty)?

This news may make a lot of people think twice. (me included!!)

Is it a big end bearing failure? Was the oil pressure low before or after the failure? Highest ever oil temperature?

Subarus often get big end bearing failure just after a top speed run, but a new short block is cheap for them.

Perhaps Nissan did not do Porsche standard high speed testing and this is not a good autobahn car. Needs more cooling, larger big end bearings, better or higher viscosity oil, cross drilled and/or nitrided crank?

In road use I can't even get my oil or transmission temperatures above about 93C, there just isn't the space to use power for any length of time so the engine has it very easy compared to autobahn use.

Will Nissan sell you a crank, bearings and rods to repair yourself? I thought they would only sell complete engines and transmissions to dealers to fit because of confidentiality of their designs, not that I believe the engine is particularly special in the sense of being overengineered like 4G63, 2JZGTE etc.

I was never expecting a engineproblem on a car that is build for lets say 1.5 years and pushed hard on racetracks all over the world...gearboxproblems because of the complexity of the gearboysystem,ok,thats what i was expecting,but not engine and for sure not after just 6500km´s...

My GTR was remapped for maybe 1000km,and most of them was normal daily driving....

Nissan definetly has a problem there and they know it,but all they do is void the warranty because a lets say 50hp upgrade...if its not build to last with 50hp more,then its not build to last for 10000km in stock trim. We all know that the engine is strong and reliable,but mine wasn´t and thats the reason im sure others will break too,as i didn´t do anything you wouldn´t do too.....

Nissan Germanys own Demo/Presscar(the one which the Sportautomagazin has done the 7.38min Lap on the Nordschleife) broke with iirc 15000km,same sort of failure after highspeed driving on the autobahn.......i can see clearly that those 2 damages have the same reason....

No,it just changed my opinion of Nissan and the GTR.....the AP is not the reason for the engine to loose oilpressure or damage the bearings....if you have got a GTR that has a perfect working engine,you will not need the warranty(as i was expecting,i was 100% sure i dont need it as its a jap build car,relaible etc.....but its not and i was wrong.

[Rich001]

I think your problem occurred when you said "the car is build solid,the engine will not break"

Fate is a bitch and will punish those who underestimate. Hope you get it sorted though and I'm impressed with the 0-200 time

[maxxwaxx]

I was just about to order an AP too after a month or so ummin and errin.
But this has made me think again, not that i think the AP has caused it but as i put in another thread it would be just my luck that my car would have an inherent fault that my surface AP or no AP. And an engine or G/Box failure would be my worst nightmare.
Let us know how you get on or what the diagnosed problem is, hope things work out ok

[IRISH]

Evolution 6, This is so shit for you and hope you get it sorted. I have had my car for a few months now and love the way it looks and drives but the whole warranty thing pisses me off too much, its always playing on my mind! I've owned some quick cars before subarus, m3's and my ;ast car was 996turbo full milltek, headers, ecu and none of my cars have give me any trouble, but i just don't have same confidence with this car, there is just something not right with all these rules and disclaimers you have to sign on day of pickup, its spoiler the fun for me, and when you hear something like this it makes it worse hope you get it sorted mate, i would hound your dealer till you do!!!

Hi Alex.

You mention that Nissan have declined your claim. What reason did they give? Was it because you have increased the BHP? or because you have modified the car? I have not yet seen a copy of Nissans warranty or what you sign when you first buy the car.

Simply on the fact i had a remap....they dont even care if this would may be the reason for the damage or not....(as i said earlier,the AP remap was not the reason,if so it would have a burn,melted or damaged piston,not the crank and the bearings...)

The simply hide behind their warranty rules....and they have enough of them...

Im pretty sure if they wouldn´t have found the AP remap,they would have found that i found the VDC off situation on tracks....or that i have been on a racetrack in general,that i have pushed the brakepedal sometimes hard(which is not allowed by the warranty rules btw),or that i farted in the seat......

All this warranty rules make me

Its mainly the way Nissan handles the situation,im waiting now for 4 weeks for them to decide whta they will do,ok,i have played with the electronics...but would have the GTR been as fast as they have advertised it,then i maybe would have not done it...mine did do 0-100km/h in 4.0sec,not 3.5sec like they say,whatever you to to the new LC....mine did go 296km/h on the straight...not 310km/h like Nissan tells us,even downhill mine did not go over 305km/h stock.....the brakes are ****ed after 6000km,the stupid oilchanges because the oil gets too hot when doing some performance driving...(my car does no do half a lap on the Nürburgring Nordschleife within the "cheap" 110 degrees gearboxoiltemp.....,so one lap costs around 1000€ for an oilchange in the next 3000km....)

All this + the fact that Nissans own Presscar broke down the same way as mine,makes me think Nissan sold us a Supersportscar that ist far from super and even more far from a sportscar....

I have spoken with my lawyer to start a legal process against my dealer(its him where i have my warranty and then i will have a expert doing a analysis of what caused the problem and if its a fault from Nissan because of a bad/faulty/broken part then they have to give me either a new engine in a very short period of time or a new GTR......they want it that way,they get it that way,i wanted to keep quiet about this,but they are not interested in sorting it out without problems.

I'm interested in hearing the results of the engine autopsy. What if engine knock physically damaged a piston - for example, cracked the wrist pin during the 300kph run, then fell into two pieces when the car went back to idle? Then Nissan would have a legitimate claim there due to ignition remapping.

I don't trust octane ratings from purchased fuel. In Korea, they could cheat you outright, and some stations have been caught with spiking fuel with various chemicals to increase profits (most industrial chemicals are much cheaper than fuel).

So I always run 50% toluene to insure octane is above 100.

But if it's something else, like a failed oil pump, well, even if the car is running 1000bhp that doesn't affect how the oil pump works. Then you've got a legitimate claim.

Im in germany,you can trust what you buy here,i only use Aral ultimate or Shell V-Power....running 100 octane on a 97 octane map doesn´t make things unsafe.......

My car did run totaly normal,even after it made that rattling noise,no bad idle,nothing,just loud,all 6 pistons where inspected by the Nissan HPC,no burnt/melted pistons,missing sparkplugs or other problems there,but a very few hairline scratches in the walls from running without lubrication...

Was the engine properly broken-in and how old was the engine oil ?
I hope it's repairable without having to buy a new engine from nissan but that's the first time I hear about such a failure. Keep us posted and good luck !
