Now hitting 140K miles, once I got a new ECU installed and recently I have suffered from malfunctioning Absolute Pressure Sensor. (The 'service engine soon' light came up, and it became okay after cleaning the throttle body. But this is the second time I had that light for the APS, and my service adviser told me that maybe I'll need to get it changed if it keeps happening again)
My 370Z is 2010 Sport and no tuning applied at all. All parts are the same as OEM, I only changed its OEM tire to Ventus EVO2. I've never been to a track, and I mostly drive very mildly. I always get maintenance at Nissan dealership, and only allow Nissan Genuine parts used.
1. Do other 370Z owners have no problem with their ECU ?
2. Anyone suffered from the Absolute Pressure Sensor ? If yes, then anyone knows what it is for ??
3. Why my APS continues to malfunction? How can I prevent it?
At first when I purchased my Z (2012), I assumed Nissan had high reliability, but now I don't think so. Even though I do my real best for maintenance following Nissan maintenance guide, sometimes I cannot avoid troubles. It seems more serious than just I am unlucky. I purchased my Z as a preowned one as 10K miles used, and at that time its CarMax inspection sheet said it was perfectly no problem.
Yesterday I paid $900 for a steering lock issue. It seems clear that the issue is pretty common to 370Z owners (especially for 2009~2011 year models). But are 370Z owners also suffereing from ECU or APS, too?
How about 370Z's own reliability? Is it reliable?
Car Brands Reliability: How They Stack Up - Consumer Reports
In 2016 Nov, the Consumer Reports said that Nissan's reliability positioned at the lowest among all Japanese car brands.
I don't look down to Nissan or its owners. I still want to remain as a Nissan fan, but actually now I'm worrying about whether I will be able to keep having my Z or not. If it costs too much for repairs then not only it is annoying, but also maybe it would be hard for me to keep it. Until now I also have had to get many other cheap & expensive parts (including a new automatic transmission) changed for repairs, but I cannot list them all here.
Can I stop worrying about my Z? I want to hear others' opinions.
* I forgot to mention that I had a 3rd party audio and two front speakers installed, but I don't think it would affect to other parts' malfunction.
