1150km on the odometer and I love this car . Only a few small gripes:

1) I'm not too impressed with the heated seats, but I think that they are getting better than they were on day one (maybe they have a break in also?). It took about 10 minutes on high before I could even tell they were on this morning.

2) When listening to the XM radio long artist names and song titles don't scroll on the display

3) So many limitations on the navigation when the car is moving, while I think some of them make sense in terms of safety why can't I scroll down a list of POIs after calling it on screen via voice command?

4.) I'm a little concerned about gas milage, given that I'm averaging 15.8L/100km (14.89 miles/gallon). Granted I am still breaking in a new engine and it is the X model, but I would like to see it a little better than that.

All this being said, they are only minor annoyances and I really really love this car. Every morning I look in my pocket to see if the key is really there, or if I just dreamed it up.

Christian, after almost 750 kms on mine, I have averaged 12.5L/100km. Are you doing all city driving? Like you said, it is a brand new engine and also you won't get as good gas mileage in cold weather....which you have had lots of lately.

Glad to hear that you are enjoying your new car. I went out in the garage last night and just sat in it for 10 mins, so I know how you feel. Glad you are getting some warmer weather out there as well.

Christian, the limitation of 5 POIs is a pain. I did find out that you can go into the configuration and change the 5 POIs so that they best meet your needs. No need to have rest stops in the top 5!

Shane, the closest I have done to highway driving is 20-25 minute streches on the Deerfoot 500 (Highway 2) going to my buddies house on the other side of town. I would say that slow moving rush hour traffic has accounted for 450km and about another 400km on deerfoot with the rest being regular city driving. I'll give it some time, and I hope it will get better. I would be more than happy to see around 13L/100km (given some impact from the AWD). I also realize that the cold weather will reduce gas milage by 15-20% so that may be a bigger factor than I was thinking.

I'm definitely enjoying the effects of this chinook, Calgary is very fortunate for getting these amazing natural wonders. It was the coldest November 28th on record for 110 years, so 10 degrees feels like a sauna.

Thanks, I'll check that out and make some changes.

That's a lot of city driving and no doubt is impacting your fuel efficiency.

Wow, a record after 110 years. No wonder 10C feels like a sauna....that almost a 40C difference since last week.

Actually, babying the gas pedal isn't really the most fuel efficient way to drive. Most cars run most efficiently when accelerating at a relatively brisk pace.

The thing that absolutely KILLS fuel economy is accelerating when unnecessary. For example, those who constantly move back and forth btw the accelerator and brake are wearing out the brakes unnecessarily and using up much more gas than needed. People who tailgate others on the freeway and constantly have to brake to avoid rear ending the car ahead, then accelerate up to speed again also waste alot of gas.

Those who seem to extract the best gas mileage don't baby their accelerator, but they anticipate traffic ahead and determine whether it is necessary to hit the accelerator at all.

The other obvious way to save gas is to not drive at excessive speeds on the freeway. A constant 55 mph probably yields the best mileage, but makes for very slow going. 65 mph is probably still fairly efficient, but when you get to 75 mph+, the gas efficiency will decline significantly.

I just took mine to the dealer about the poor gas mileage. I was seeing about 14 - 15 mpg and at best 21 mpg pure highway driving.

They said my left bank was at 104% and my right bank was 102%. They reflash and now they are both at 100%. Don't really understand what they did or what this means but so far I don't think it has made much difference. But we'll see. I have about 900 miles on the car.

my 2 cents:
-the Nav has great functionality and many annoying interface quirks - but so far everyone who has seen it tells me it is easier to use than theirs
- am getting ~19.5 mpg over all and once got 24 on a road trip, both fair given my inability to keep my foot out of it and seek out on ramps.
- I have no use for the rear CD changer, given the other music access options, my severe dislike of the clueless avoricious CD industry, and know it will someday get in the way
- would be great to have a folding rear seat
- had no nav in my 03 and really miss that center dash cubby for stashing stuff
- would like a change holder insert or better yet a cell phone holder/charge plug friendly design to replace the ash tray

Can someone explain what this means?

Also, what method are you guys using to determine gas mileage? The on-board computer?

Woah wait. It sounds liek I would be getting worse gas milage than my Maxima. I was hoping to get at least 18city. and I would say 80% of my driving is less that 5miles at a time and most of it is city.

Disclaimer: I don't know much about Nissan's engine management program, or the software that the dealers have to scan the parameters. My experience is with tuning GM cars for performance, and some of the termonolgy and techniques might be different. Hopefully, someone with more knowledge than I have can chime in on the subject.


I can only guess the dealer is referring to the fuel trims for each bank of cylinder. Here's an overly simplified explaination (that leaves out the different conditions the car uses to calculate this info): The car has default levels for fuel (which I'm guessing is 100% for the dealer's software, with the software I use it is a numeric value of 128). There are short term and long term fuel trims. As the car monitors the air/fuel ratio based upon your actual driving, it adjusts how much fuel there should be to reach the ideal air/fuel ratio (14.7:1). If the short terms keep getting adjusted to add more fuel (greater than 100%) the car will make an adjustment to the long term, so that the short terms go back to 100% while the long terms are then increased above 100%.

Again, as a guess, I assume the dealer is referring to the long term fuel trims. In this case, the car has added 2% of fuel to the right bank of cylinders and 4% of fuel to the left bank for the car to achieve the proper 14.7 air/fuel mixture (i.e., this car was running lean by default so the computer added fuel).

So the dealer reflashed the program in the computer, which reset all the values (in some cars, disconnecting the battery for a while would have accomplished the same thing)

The problem with this is two fold. 1) I doubt the 4% and 2% caused a huge decrease in mpg. 2) Unless the program that the dealer put in is different in other ways (different timing or other parameters) the car will pretty quickly relearn back to the 102 and 104 values.

I'm using both the computer and mileage. When I fill up the tank and drive 300 miles and need to fill up again I don't need no stinken computer to tell me it's sucking gas.

I think you're pretty much right on z28lt1. They said something about the idle adjustment as well and I'm thinking what has the idle to do with overall gas mileage? Maybe if I sitting in traffic for an hour.....

Disconnecting the battery is not a bad idea since it should reset the computer.

I cannot find much wrong with the car at all I'm lovin it.
My only complaints are to do with storage space. THere is virtually none in the interior glove boxes, and the trunk is going to be a problem for me. Today I had my snows installed and I brought the stock 17's home in tire bags. Well, I had to put 2 on the back seat, but I could barely put 2 in the trunk because of the trunk CD changer. I had to force the 2nd tire in past the changer. If they were mounted on rims I don't think I could have got the second one in .
I guess we will travel light with this ride .
