Electric Power Steering Fluid (E-PSF) Service Interval?

[spamcop01]

Sorry if I missed the answer to this particular question, but why doesn't the Nissan Service Manual have anything about "Replacing" this E-PSF at particular intervals? Instead, at least in my 2013 Service Manual, it only mentions "Inspecting" and topping it off if it's low.

I've seen other threads about how to drain & fill the E-PSF for other Nissan models around the model years of my Quest, but just curious why it's not a recommended maintenance item?

BTW, the reason I've taken an interest in this is because the rack & pinion has had a small leak from/near the bellow on the driver's side. I used a fluid extractor to remove about 2 ounces of E-PSF and replaced it with ATP AT-205 Re-Seal. Had one drip a couple of days later, but no drips in over a week and several hundred miles of driving. However, it got me thinking that perhaps I should drain & refill all of it in the next few months and couldn't find a reference in the Service Manual...

I've never actually seen what seemed like a fluid-related failure in an EPS. For most purposes it's what Nissan wished CVT fluid was, lifetime fluid. Since you had a leak it might be a good idea to spill and fill it, but only because it may have got contaminated.

Thx! Assuming there are no further leaks, I'm going to let the AT-205 do its thing for another few thousand miles and then I'll do a spill & fill.

Just one more note for the CVT haters out there: I'm not a Nissan or CVT fan-boy, but my 2013 Quest has been one of the most dependable cars I've ever owned. We owned a 2005 Honda Odyssey before the Quest and it had numerous issues. My other 3 current cars are all Acura TL's ('05, '07, '08) and they are nearly bulletproof.

Bought my Quest in Dec 2016 with just under 24K miles on it. I do almost all my own maintenance and repair work, but there hasn't been a single thing that's cost me more than $100 to fix over the last 8 years and only 3 minor things come to mind: front passenger side lock actuator, drivers side half-axle because the inner boot was ripped, and front struts at 110K miles. Maybe I'm just lucky, but if you maintain your vehicle and don't drive it too hard, it's going to last. Just crossed 140K on our Quest and it drives perfectly.

I own a high-end code scanner and I've been scanning all my cars over the last week or so. All my Acura's report some issues related to things that I had to disable or they would drain the battery. I just did a scan of my 2013 Quest after several drive cycles and 1K+ miles and it came back with ZERO DTC codes or errors. Again, maybe I'm lucky, but maybe it's because I pay close attention to everything going on with my vehicles and if there's even the slightest indication that something needs to be addressed, I do it without hesitation. The single dumbest thing most car owners do is ignore when something isn't right because they "hope" the problem will just go away and fear that their mechanic will tell them it's an expensive repair.

"Hope" is not a strategy, and ironically, the longer people ignore the warnings their cars are giving them, the FAR more expensive they become...
