I was recently given an 07' Murano with 80,000 miles. It doesn't seem to have any noticeable problems. I wanted to know what I should do to make sure it lasts as long as possible trouble-free.
GET RID OF IT IF THE YEARS ARE 2004-2009, ASAP, forget about making it last, shit boxes are heavily flawed with known COMMON transmission failure, if you happen to get lucky, it's failing ABS, and soft brake pedal... I wouldn't advise this car to nobody.
keep up on the service schedule in your owners manual.
I mean, that is the worst year of Nissan's. It's a french modeled car made cheaply but the transmission will go out no later than 120k miles no matter what which will total it mechanically so I would get rid of it and get literally another car. Just refrain from buying used CVT's, especially if it is a Nissan. Just change the transmission fluid in time if you want to keep it like 30k miles.
well if you sell now you'll get a few thousand so might as well keep it. drain and fill cvt fluid now with dealer nissan fluid and do it every 30k, do other scheduled maintenance
Change oil to Mobile One synthetic and change transmission fluid per the owners manual intervals.
Stay on top of maintenance and the Murano will last. That should be a Japanese build and they are pretty bulletproof with the 3.5 and those years cvts are not bad As long as they are maintained. I used to have one of those and I miss it still I have a 2009 now and it has 234k on it and still works perfectly. I would recommend keep the car maintain it and drive it
