    No problem. I know for sure in the Q45, the memory settings work for the steering wheel, seat, and mirror settings. Don't know about the other models though, except for the I35. I'll have to take look at my manual to see what it says, as I have not read that section.

    Can someone help me with the possible purchase of the I35? Is the ride better now than in the 2000 model I30? My son has the I30 and it is not a very good ride(does not absorb bumbs well). Have things on the I35 changed in reference to the ride?
  • jhinscjhinsc Posts: 399
    I don't know how the 2000 I30 rode, but I do have 2002 I35 w/ sports package. It's a taut ride, but when compared to a 2001 I30 w/o sport package, the I30 rode more like a luxury car. At first, I thought the ride on my '02 was a little stiff, but after driving the 01 I30, I wasn't happy with how it handled but it did ride smoother. If you're looking at an 04 model, the sport package is not available on that model year, so it should ride smooth. Keep in mind that many dealers keep the tires on their cars over-inflated a bit to avoid a flat spot while sitting on their lot. I recommend you go test drive one and see if you like it.

    Thanks for your reply. How about mpg with your I35?
  • jhinscjhinsc Posts: 399
    On the open road, I get between 26-28, with cruise set on 70-75. Around town, I get between 22-25.
  • fredvhfredvh Posts: 853
    Is this by filling and re-filling the tank or are you looking at the trip computer? Thanks
  • jhinscjhinsc Posts: 399
    My mpg figures are calculated by the filling and refilling method. You can't go by the trip computer, it's too optimistic. I really wish I was getting 27-29 mpg in mixed/city, and 32-34 on the hwy as the computer says. The distance-to-empty seems to be fairly accurate though, so I don't know why the mpg number is so far off. I brought this to the attention of Infiniti service, and they checked it out and said everything was ok. They said it's only an estimate and not a hard number.

    What is the RPM on the I35 at 70 mph?
  • Hi, there
    I noticed mine(2004 I35)is above 3500 at 70mph. I am not a auto gurus but my previous honda civic is around 2500rpm. So what is RPM on yours? Have you get some answer yet? If it's not normal we have to visit dealer to check.
  • fredvhfredvh Posts: 853
    Mr. Young,
    I am considering buying an I35 but you state that the RPM at 70 mph is approximately 3500. That is too high especially if one is trying to get a reasonable mpg out of this vehicle. I am hoping some other owners let us know what their RPM are at exactly 70 mph with the 3.5l engine.
  • jhinscjhinsc Posts: 399
    Just make sure the shifter is set at 4 and not 3. You can move the shifter left and right to change from 3 to 4. Once you're in 4th gear, your rpm's will drop significantly. At 60, you should be running 2000 rpm's, and at 70, it will be below 2500.
  • fredvhfredvh Posts: 853
    Can someone give me the exact RPM at exactly 70 mph? Thanks so much.
  • This is my first gated shift car in my life.
    After one month I even didn't notice that the D is there - which is very close to 3rd.
    My shifting style made me easily put it into 3. More confused to me is that infiniti dealer (north houston) service consultant have never given me hints like this when I called them. The transmision will damaged if...
    Thank you very much!

    Hi, I just try to pump 100 octane racing car fuel from 76 station. What I did was pumping about 8 gallons 100 octane and the rest was 91 octane. So that way I would get about 95 octane. After that, I listen to the knock around 1800-2000 rpm where it usually happens on my car. The knock is gone. I have been driving the car for a week now and the knock really is gone. So I suspect that on the I35 engine, there is a problem to the low or even 91 octane. I took the car to the dealer several times and it even checked by regional engineer but they can not find out what the problem is. They just simply said the knock is normal. Try it to find any gas station that carries 100 octane and do like what I did but for only one time. After that I guess you need to pump 91 octane only.
  • jhinscjhinsc Posts: 399
    I suspect your car may have a problem with the knock sensor. Running 87 octane shouldn't cause any knocking, but you should notice a drop in power and fuel mileage.

    I just had the oxygen sensor go out on my I35. My 'Check Engine Soon' light came on a couple of weeks ago, went off for a couple of days when it was really warm, then came back on when the weather cooled off again. It's being replaced under warranty. If you want the service dept. to recognize your symptoms, you should fill up with 87 octane gas and then take the service rep for a ride so they can hear the problem. I've never had a problem with Infiniti service telling me something was 'normal'. After all, thats why I bought the Infiniti, and not Nissan or Toyota.

    I am glad you now know the proper gears. Could you now give us a RPM reading at exactly 70 mph? Thanks

    I just closed on an I35 today, and the clock isn't moving. It's stuck at 10:05. How do I adjust it? And how can I get it to tell the right time once I've adjusted it?
  • jhinscjhinsc Posts: 399
    Congrats on your purchase.

    You can change the time by turning the the little knob right. If you hold it, the minute hand will keep moving until you get to the right time. As far as why it's not moving, I can't help you there. Maybe a stop by the dealer service will get it resolved.
  • jhinscjhinsc Posts: 399
    I finally looked at the rpm's today while on the road. At 70, it spins at 2400.
  • fredvhfredvh Posts: 853
    Thanks jhinsc. I appreciate that you took the time to post back here. I think most of the new I35s are gone now.
  • jchan2jchan2 Posts: 4,956
    Infiniti of Cincinnati still has about 45 of them.

    I think Quirk Infiniti (Boston MA) still has around 30-35 I35s left.

    And my local dealer is down to their final 2.
  • jhinscjhinsc Posts: 399
    I replaced the Bridgestones with new Falken Ziex ZE 512's, and boy what a difference in the ride! The Bridgestones always rode harsh, especially if I kept them at the recommended 32psi. Now, I have the Falken's at 32psi and they ride much smoother and quieter. Early on, I thought I was going to be stuck buying the Bridgestones again since my size is 225/50-17, but more manufacturers are now making this size. The big plus is they are much more affordable then the Bridgestones, by almost $300 on a set of 4, plus they have a 30k mile warranty and a 260 treadwear rating. The original Bridgestones had a 160 treadwear rating, and I had 39,000 miles on them when they were replaced. I probably could have driven them another 5-6k miles since they were not down to the treadwear indicators yet, but they didn't track very well during wet road conditions.

    Does Sams Club carry any tires that fit the I35? I know I'm thinking a little ahead (my I35 only has 300 miles on it) but its nice to know where I can get tires when the time comes to change tires.
  • jhinscjhinsc Posts: 399
    Yes they do, but the brand, Goodyears, are significantly higher priced than the Falkens. One of the primary reasons I got the Falken was the top rating it got from Consumer Reports. I got mine at Sears. They were on sale, and at the time I bought, they had a 10% off deal if I used the credit card. I got them for about $105 each before tax, mounting and balance. Sams Club's tire are going for $156 - $168, depending on the tire you buy.
  • A few months ago I traded a '94 Nissan Maxima for a 2004 I35. I love the new car, but the Bose radio in the I35 doesn't tune FM stations nearly as crisply at the Bose in the old Maxima did. Maybe it has to do with the different antenna setup, but the FM stations often sound muddy with hissing "S" sounds. I thought maybe the FM antenna was not attached properly, but the dealer says it's fine. Anybody have the same issue?
  • jchan2jchan2 Posts: 4,956
    So far my FM Radio reception has been pretty good.

    So tires for the I35 are readily available right? Any Michelins available for the I35? Or is it just Good Year and Falken? No other brands?
  • jhinscjhinsc Posts: 399
    There are Michelins available but they can be some of the most pricey tires you can find, depending on which specific tire you choose. A local retailer quoted me nearly $1,100 for a set of four, installed out the door price. The Falkens cost me under $500. Because I have the sport package, I need 225/50-17 V rated tires in order to maintain the original driving characteristics. For non-sport pkg I35's, the size is 215/55-17 H rated. The H rated Falkens come with a 60k mile warranty while the V rated ones are 30k miles, and the H rated tires did not come in my size. So for me, putting a lot of money into tires that I realistically will only get about 40-45k miles out of didn't make sense. I would have preferred to have Michelins, but not at the price they were wanting for them. For your I35, you can find Michelin MXV4's at a similar cost to the original Bridgestones. One thing I don't understand is why the Bridgestones are so pricey when they are really not that great of a tire to begin with. My previous car was an Acura RL and at 30k miles, the tires looked nearly new, and could have lasted at least 60k miles, if not more. In the end though, I would not have bought the Falkens if not for Consumer Reports.
  • jchan2jchan2 Posts: 4,956
    I don't understand why they're so expensive either. The tires are just marginal. But, the Bridgestones on my 97 Accord lasted 87,000 miles before I made a trip to Sams and replaced them with cheap Good Year Allegras.

    I just purchased a used 2002 I35 with 16k miles for 18,900. I have a 99 I30t that I just gave to my daughter. I remember when I got my 99 I30t that you could go to the Infiniti website and get an owners manual free of charge shipped to your house. Now the only option is to print a PDF file that is 300 pages. Does anyone know how to get an owners manual for my 02 I35?

    I will post more to this site in the future when I get more experience with my new I35. If it is anything like my other Infiniti - there will be no problems.
  • jchan2jchan2 Posts: 4,956
    I guess you could go back to an Infiniti dealer and ask them to order one for you. It might cost a few dollars, but I believe its worth it.
