  • Hi all..First time poster here on the board. I am getting ready to look for a low milage..pristine..2003 Qx4...Need some advice over all when looking for what I want. I found a few with 38k - 41k miles offered at $23k - $24k. I think a low milage - well kept 2003 QX4 would be around $20,500 - 21k...?...Thats the price I am going to offer as i am putting 11k down..Im looking at dealers right now....

    Any advice on the Infinity Extended warranty?...and the price?

    Any over all info about the 2003 and your used purchasing experience helpful

    Thanks,

    Lance

    I just purchased an 03 QX4 2wd a few weeks ago. 36K miles. Pristine one owner with all up to date service records. Drove it out for $21k including Tt&l.

    I am new to the board and need some help. I am looking at buying a 2001 Infiniti QX4 and would like to know the pros and cons of the vehicle. Also what do you think a 2001 with about 50k miles is worth, it's silver/grey and looks to be in great condition.

    Thanks

    Somehow my compass is blinking all the time sine yesterday, just the compass "meter", not the direction...not the N/S/E/W, but the I---I---I below them.

    couldn't find any info on the owner's manual, anyone have this problem?

    thanks.

    Possible fix to CD error discovered by accident - I also had the cd error about experience three weeks ago. It just so happened that about the same time I needed to replace the battery in my 2001, which still had the original battery. Because the power to the vehicle was disconnected while I changed the battery, the cd changer had to re-initialize. The error message went away, and it's been working fine for the past two weeks.

    So you may want to try disconnecting the power for about 30 minutes so the system will reset.

    J.D. Powers sent us a survey regarding our ownership experience of the 2003 QX4 which we bought new. When we got to the "Problems" section, we skipped all the pages because we have no problems except for a door lining that had loosened.

    When I think about all the things that could be wrong, I have to give credit to Infiniti for manufacturing a trouble-free vehicle that's now three years old.

    I was wondering if there was a 50k service for a 2001 QX4. I also wanted to know what would be included in that service.

    Check out the Edmunds Maintenance Guide - service info should be in there.

  • Some time ago, I had the typical Err 2 message, and had a local car stereo specialist take care of it. In the process of talking, however, he informed me that the system in the QX4 is pretty elaborate with separate amplifiers for each speaker, and that explains the low ohmage rating. If my understanding is correct, the system is designed to all fit together, and it might be difficult to just put in a new unit. Possibly someone out there has had a different experience?

    Also, you might also try the Pathfinder forum, as it gets a lot more traffic, and would have the same mechanical issues.

    Good luck,
    Stan
  • Bought my wife a '03 QX4 at a toyota used car dealership in November 05 with 17,990 miles on it for $24,500 including taxes and registration here in NYC! I used the website from the dealer but when I went to give final payment for delivery the "dealers manager" said the price should have been $26,000 because of the documented low mileage! What a scam but I still got it for a great price at $24,500.
    My wife loves it and other than having the radio replaced for free because the CD started to skip very bad, its been a great vehicle. The car is still under the Infiniti warranty for another 12 months and I will be purchasing an extended warranty. She wants to keep it so it will be worth the payment for the warranty.
    The QX4 is a great vehicle!

    Glad you like QX4. Mine is 02 4WD with 39K miles. No problem at all so far. The only "problem" is one time in Reno I couldn't start it in cold morning. However in the middle of call 800 roadside service, it started fine.

    My friend's Pathfinder has no truble too. He bought extended warranty but felt like a total waste. I didn't, as I know it'll be a waste (statistically).

    If a Qx4 shows a steady engine light on ( service engine soon) and it is jerky in motion on the free way when cruising between 50 and 60 mph, the dealer is quoting $450 just to diag/check and quoting 75 for coolant check and advise. It seems very high to just diag and check to me. Any comments why I should not go to a non dealer maintenace like speedee for these types of services, especially when the mileage is high on the car $80000? Your replys are greatly appreciated. I am very grateful to those who responded on the cd player, on my previous posting.

  • Sounds like it could be the TPS (throttle position sensor), but I'm not a mechanic, just a guess. Regarding your questions, my experience is that any diagnostic check should cost around $80, maybe $100, even at a dealer. And, the only thing that a dealer's mechanics can do that others can't is to re-flash the ECU (electronic control unit). So, if you have a mechanic that you trust and who is capable of doing all the same diagnostic work, I would go there. However, that's with the exception that sometimes in these issues (i.e., replacing O2 sensors or other items), a recommended part of the procedure is re-flashing the ECU. And, in that case, a visit to the dealer may be the best remedy. However, I would procede with caution. In my last visit to a dealer for a SES light, they wanted to replace two O2 sensors and re-flash the ECU, and then look at several other issues. I told them to just do the sensors and got out of there.

    Thank you for your reply.
    I took the car to my trusted mechanic, who finds the problem is that it ran out of coolant just as I suspected. As a matter of fact, as soon as I saw the steam coming I stopped the car, and after an hour, opened the radiator cap and the reservoir to check the coolant level. I even walked to the nearest parts store and bought the coolant, but was not sure if adding it myself without verifying with Road side assistance ( whose consultants were not available on Sat) consultant, if Prestone coolant was OK to use. In short, my mechanic says after filling the coolant, the light went off and he says the car is running without any other problems, however he wants to do more checking on the electronics, wires etc. I will keep you posted how it goes. Many thanks. To hosts - this forum is very useful.

    Here was the problem:

    From OBD II diagnostics, they found Engine coolant over temperature condition (P0217 ). In addition, coolant was leaking from the radiator (top). Went ahead and replaced radiator, coolant as major, and had the wires running beneath the car were all checked. Cost was close to 800 including towing expenses.

    Does anyone know whether Infiniti has any plans of bringing back the QX4 (or something similar) to "compete" with the Pathfinder?

    i'm a newbie to the forum. own a 02 QX4 with 37k on it no problems whatsoever. i am tired of paying dealer price for maintenance. can anyone recommend a few independent mechanics in the los angeles area? the closer they are to the san fernando valley the better. thanks so much in advance.
  • Can anyone help me how to install both serpentine belts? as i have no idea how to relieve the pressure off the belts? On my old pontiac, it was a simple tensioned pulley that a long rachet would do it, but on qx4 how do i go about it? Many thanks.
  • can anyone share with me the .pdf file of the service manual? Thanks.

    I need help. I have a 99 Qx4 and when I have the air on and turn the lights on my speedometer, odometer and rpm gauge go blank. If I have just the lights on or just the air on this doesn't happen. I have replaced the alternator and the battery. When I turn the car off for a few minutes they work again. Any suggestions?????????????
  • senunezsenunez Posts: 2
    Now if I just turn on the lights and everything else is off the speedometer, odometer and rpm go blank. Everything else is fine. Please help!!

    My 2001 QX4 had the exact same problem today. I was driving on the highway (60-65MPH)and noticed that the car was hesitating. I knew something was not right because the "Servie Engine Soon" light has been on/off for a while. I pulled over and noticed smoke coming out of the engine. I had the car towed to the nearest dealer. I will know the damage tomorrow. I'm keeping my fingers crossed. :)

    My 03 2wd 41k miles has a rattle coming from the front end sounds high up near the cowl area when going over rough road. More prominent when the truck is cold or for the first 5 miles also noticable when the truck is loaded down. When warmed up it takes a stiff bump to hear the noises. Almost a metallic noise. Still under warranty, thank goodness. Taking it in to have it looked over. Anyone had a similar problem. I am worried they will say there is nothing wrong or cannot duplicate the noise on a test drive.
  • wildjaxwildjax Posts: 2
    I HAVE AN APPT SAT W/ INFINITY (IM STILL UNDER WARRANTY) WITH 29500 MILES ON MY QX4 I NOTICED A VIBRATING NOISE. IT IS ONLY WHEN ACCELERATING. BUT IT HAS GOTTEN LOUDER & LOUDER OVER THE LAST MONTH. ILL LET YOU KNOW WHAT THEY SAY. IM SURE MY NOISE WILL BE THERE ON TEST DRIVE IT HASNT GONE AWAY. :mad:

    I had the same thing. 2003 model. Sounded like coming from the dash or foot well on the passenger side. The dealer had a mechanic ride with me on rough roads. They determined that one of the body seams was rubbing or popping in the passenger foot well. We could never figure out which one so we took a screwdriver and separated seams (just a little) that looked like possible causes and I forced silicon caulk in all the cracks between them. It fixed it and no more problems. They found a service bulletin about a similar problem that required taking off the fender and other parts to get to the problem of a loose seam but we didn't have to do that.

    We had a very bad experience with our Infiniti QX4 recently. If you recall in my previous posting, I had mentioned that we replaced the radiatior as it was found as a cause of the overheating. After that, we had two or three subsequent car failures due to overheated engine. We took the car to the dealership twice and they replaced thermostat first time, removed air bubbles in the coolant/radiator system. We spend about 2 grand on these repairs plus towing costs. Dealership now figured out that engine is burned and we need to replace it. Has anyone has this kind of bad experience with Infiniti QX4 and are there any known recalls with Nissan PathFinder engine? Appreciate your response.
