#2369 of 3411 2004 FX35..Air Recirc question
Dec 21, 2004 (1:58 pm)
We have a 2004 FX35, that will be a year old in Feb. I've noticed folks complaining that they only get hot air with the fresh air intake on, climate control off...oddly, we've never noticed that. However, we have noticed that if one wishes to recirculate the air, instead of having fresh air (like when you encounter stinky skunk smell..or stinky exhaust from other cars) there is no way to do so without the A/C kicking on. The manual does not mention this specifically, and I'm wondering, is this just our car...or, is this normal..and why?
Also, at not quite 10K miles, we are hearing a brake squeak as we back out in the morning. I saw another post about this, saying that Infiniti is aware of the issue...but nothing since. Any additional news on this?
Last but not least, we LOVE this car. It is the greatest car we have ever owned..and blows away our last car..a Mercedes. This is definitly a keeper!

There are not alot of nits to pick on the FX, but somebody screwed up on the lack of fresh outside air. With the A/C off and just the two lights on the top left on, air must come through the hot engine compartment and around the battery area to come into the cabin.
Two things wrong here. One is the hot air and Second, I hope the battery never sulfates or otherwise lets off toxic fumes (I guess hydrogen is OK)??
This engineering goof makes the FX a very A/C dependent car, which wastes energy when cool outside air is sufficient.
I can only surmise that this was done to direct ouside air through the microfilter. And so I assume that all the intake air for the A/C is hot to start with, which must do loads for A/C efficiency!
My solution is to turn off the system entirely and open the windows and/or sunroof.
The real solution is to rig up a flexible hose going from the battery compartment to the front of the car. And make that an insulated hose.
Maybe I could make a retrofit kit and sell...
#2371 of 3411 Linking seat memory to a remote key

Does anyone know how to link the seat memory to a remote key? There is a little smart tip note in the car that says you can do that and asks you to refer to the manual but I can't find it in there. I have a FX35 with tech package. Thanks.

From memory (no pun intended) I believe the procedure is:
With the car running and it in park, push and hold the MEM seat button until it flashes, then press and hold the memory button (1 or 2) that you want to memorize, when it flashes, press the lock (might be unlock?) button on the key fob you want to register to the memory seat postion (1 or 2).

dklanecky is correct on the procedure and it is the Unlock button on the key fob.
I find I have better luck adjusting and setting things when I do it without the car running, but with the key in the ignition and turned to the first "click"... just before all the dash lights come on.
#2374 of 3411 93 VS 87 Octane and gas mileage FX35
Dec 27, 2004 (6:51 pm)
I am looking at purchasing a FX35 but am not thrilled bout the gas mileage or the premium fuel recommendation. Id like to know if anyone is running 87 octane as the dealer says I can, and or what highway gas mileage they are seeing.

I have ran my 04 on 87 octane since new (with 20k) miles. I am getting an average of 18 to 19 miles to the gallon depending on how much city vs. highway miles there are on the tank. It runs just fine on the lower octane.
Dec 28, 2004 (3:03 pm)
I started on 93 but when gas prices went silly I went to 87 and haven't looked back. Pre cold weather i was averaging 18.1 in my typical Houston commute 23 miles oneway mostly congested interstate. The last month or so I have been running around 17.3 mpg on the same commute. I haven't took it on a road trip since I switched to 87 but on my last signifigant trip it was about 22 mpg at an avg speed of about 75 mph.
You will lose some power however as a bunch of FX owners here in Houston got together and did some instrumented testing of the FXes. The ones running 93 ran .2-.4 seconds quicker the the one running 87.
Also my numbers are for a RWD FX not AWD. I have 29k miles on mine.

I agree with the comments made so far. If the cost of fuel is critical to you, it is important to remember that for every 1 mph over 65 mph you drive, you will lose about 2% in mpg. I routinely drive the posted 65 mph from the Houston suburbs into the city (50 mi) and get 25-26 mpg. If I drive this trip at 75 mph, I get there maybe 2 or 3 minutes earlier, but get 22-23 mpg. If you do the math, the premium you pay for 93 octane, considering the overall cost of operation, is just not very significant unless you drive fairly fast and for a lot of miles/year (35K+). Anything over 12K miles/year and the depreciation on your car far outweighs fuel cost.

I get just under 19 mpg with either 93 or 87 octane. That's a mix of city and highway in 2003 FX35 AWD.
