Hi Everyone I am new to the Forum but have had my 550 since new in 2013, and got around 120K on it now, two times it has had issues under warranty where the air con would not start or work, VDC off would come on, Cruise control would not work so they fixed it once, then the second time it happened 3 months before the end of warranty with all the same faults as before but now acceleration was affected and patchy sometimes at lights there was a huge flat spot of nothing then all of a sudden everything at once.
Now before this I was its greatest fan and have owned and supported Nissan products for a great many years but now through the dealer networks there is a new system which I am very unhappy with, its where the last fix lasted 1 month but was to busy but also it had started dripping oil which was only tiny and I did not bother to look to much at that time into it but it was there when it went in for the last warranty.
now I reckon all they did was clear the computer, so 2 months out of warranty it start dumping to limp mode with no fault showing and all the other boogy man things were back.
SO take it the the dealer who sold it and did the warranty here at Caboolture and get told how very lucky I am because its out of warranty but the Big hearted people at Nissan will pay 70% of the repair, $2,500 for a new intercooler which they have known for a great long time won't last or stand up and $1,600 for a new sensor that shows as faulty but please be aware they say that that is the only one we can currently see so there could be many more.
Now naturally I said I am not feeling very lucky but this is my warning here that sitting in the service lounge I got to hear many other lucky souls being told how lucky they were because Big Hearted Nissan was also offering them 70 % of the repair price for faults that were there while under warranty and the dealer had not fixed.
Ok that said I have consulted to Auto Electricians about these fault codes showing and one said they needed the work vehicle for 2 to 3 weeks to test in between diagnosis, now they are good guys but man the Faults this thing was throwing was like throwing darts at a dart board, Unrelated stuff from low power to gear box sensor, there were no kidding 20 different fault codes and so many where random so far removed from any sequence of logic. so what I am saying is the system they use, they don't even trust it and all they are doing is picking the most logical from the group and they start replacing from there, but at $1,600 a shot I am not feeling lucky even with a 70% discount for something that was there under warranty, in a 10 K drive it will drop to safe mode 15 to 20 times sometimes immediately the accelerator is touched, now yes that is being driven to the workshop for the testing, we had both the Brake pedal sensor and I forget what the other one was on top of the engine replaced but it now says that its a faulty MAP sensor out of range, now you ring Nissan for that part and get told it does not have one, now this was the original sensor fault picked up but the other tester showed the different sensor so the Auto electrician changed that one which I am fine with as he changed both for around $300 rather then $1,600 that Nissan wanted.
The whole diagnostic tools and system they use when pushed on it they say and this is Nissan is that your Intercooler can affect all the gremlins that were wrong with mine from Air Con not starting, to VDC OFF malfunction, Cruise Control, to random accelerations issues to poor gearbox changes, to pretty much every gremlin you could think of in the computer. SO my warning to you all is if you have any fault while under warranty hammer they hell out of them before you become lucky like me. Before this its the best car I every owned and after this its the last Nissan Product I will ever buy. I guess the real thing I want to make sure people understand is from a mechanical sense non logical things happening and randomly as they did and then would go away. were left because this is our main work vehicle and we simply find it so hard to put it off the road, But if anyone know where they keep the MAP sensor I would be extremely grateful to know.
