#1436 of 2128 Re: 2005 Quest Warped Rotors
Aug 06, 2005 (8:25 pm)
As I am reading about dealers machining rotors to fix the vibration problem, to me this is a short term band aid fix. Obviously, when the vehicle was brand new, it didn't have this problem, which means the rotors are good. So after a short time of ownership, the rotors gets heated and cooled repeatedly and eventually warps. The rotor is basically a big mass of a heat sink (to dissipate heat). The dealer's solution is to machine it which is to take more mass out of the rotor. But now you think, whatever the reason it was in the beginning that caused the rotors to warp still have not been fixed. Now your rotors are thinner which means it's a smaller heatsink and more prone to warping. After several more times of machining, your dealer will tell you it can't be machined anymore, and will need replacement. Then your next brake job will be very expensive. I can only guess that a Nissan rotor is around $100 - $150 each. Nissan needs to step up to the plate and fix this problem once and for all.

For more info. on this problem go to www.nissanhelp.com on the left side of the page see ownership, click on diagnose, select model,Quest, See Suspension,ABS,Brakes,Tires. Click on Brake Noise/Judder/Pedal Feel/Diagnose and Repair TSB. This Tsb will explain the problem according to Nissan, too much run out on installation of rotors. I have had my rotors resurfaced with this PRO-CUT machine. They seem fine now. If you go to the PRO-CUT website you will see that this machine is specified by most all the auto makers. It seems this is not just a Nissan problem. If my rotors cause vibration in the future I will know this was just a bandaid fix. I sure hope not. Time will tell. I will keep the forum informed of developments.
#1438 of 2128 A/C Temperature
Aug 07, 2005 (7:45 pm)
I went to the dealer Saturday and worked with the Service manager on my Quest SL A/C not cooling enough. He brought out a analog thermometer and the dash measured the outside temperature as being 88F, then with the A/C switched on to fan speed 4, the lowest reading we got from the vent was 61F. Now 61F seem cold, but typically a good working A/C would have vent temerature of 40-45F. By the time this cold air blows into the cabin, it would rise by 20 degrees which will cool the cabin to about 70F. We sat and looked at the reading for 10-15min and it stayed at 61F. I told him it doesn't cool the vehicle enough to be comfortable, but he disagrees saying R134 only cools 20degree below ambient temperature. The service manager even challenged my knowledge of A/C which really piss me off. No, I am not a mechanic, but at the same time, I have owned 4 other vehicles which had sufficient cooling. I am going to wait a few weeks and take it in to have the techs check the R134 level.

I know this sounds obvious, but I have to ask due to my experience with my 2004 Quest. When you turn on your A/C, is it recirculating cabin air or pulling fresh (hot) air from outside? One of the quirks I noticed with mine, it always defaults to pulling fresh air from outside, and in this summer's heat, it NEVER gets the cabin cool enough. As soon as I switch over to recirculation, it cools down immediately.

Thanks for all your help and research on this topic. I took my '04 Quest into the dealer at 7:30 this morning. The fellow who wrote up the problem again mentioned the brakes as the probable cause, but the guy who actually worked on the van said it was feathering in the tires due to them being out of balance and suggested replacing all four tires. He didn't say anything about the brakes. We've had the tires rotated without fail every 7500 miles, but just had them balanced once, last week. Van has 40000 miles; tire wear appears even and normal to my eye.
Here's my dilemma: Would they NOT mention the rotors as a solution so they wouldn't have to perform warranty service? Since I'll be out of warranty in another 20,000 miles, they might think I'll need pad replacement around that time anyway, so I could then return as a paying customer for a complete brake job. Make money on tires now, make money on brakes later. Sounds like a car dealer to me.
Considering the tire mileage, I'm going to replace the front tires and have the alignment checked, but not at the dealership. If the alignment is OK and the vibration continues, I'll take the thing to another Nissan dealer across town and get a second opinion.

The recirc will surely cool the cabin further, but you shouldn't need to use it after the car has been driven for 1/2 hour or more. Once the cabin is cooled, the regular A/C (without recirc) should have no problem keeping the cabin cool. I don't live in Texas or Phoenix where temperature is 100+. That day it was only 88F outside. Also if you use recirc mode all the time, after couple years, your A/C will have that stinky moldy smell. I am going to investigate further and will try to find the exact spec Nissan has for the Quest.

Well, then, we would be in the same boat, as my Quest's A/C doesn't get the cabin cool if it is mixing with outside air. I always have to use it in recirc mode. Outside temps above 90F this summer.

How much tread you still have on your tires? If it's a tire problem (according to your dealer 'Nissan'), then take it to a Goodyear dealer have them prorate the tires when you get the replacement. Like you said, you rotate them to schedule, so you are not at fault for neglecting these tires. If Goodyear dealer say it's not the tire, then you tell your Nissan dealer to talk to them and let them battle it out. Don't let them push you back and forth on this. Demand a proper fix for your vehicle and if new tires don't fix the problem, tell the dealer to put in writing that they will pay you back for the new tires. Why should they pay, because they are the one that misdiagnosed the problem in the first place. I might sound bit harsh with this approach but if you don't stand firm on this, you will pay $$$$$$ at the end.

Any brake or tire shop can put a device on your rotors to check for high spots or run out that would cause vibration in the steering wheel. It sounds like your dealer may not have purchased the Nissan mandated Pro-Cut rotor lathe yet. Ask them if they have this machine. If you are going to buy tires have that shop check your rotors first, I bet they are the problem.I bet at 40k miles the dealer does not think Nissan will pay to resurface your rotors. At least they could have checked them.Good luck.

I have a problem and was wondering if any one else has experienced this problem. I drove my vehicle on Saturday all day and parked in my garage, when I went to start it the following morning it would not start. The gauges were bright and everything worked just not enough power to turn over. I jump started it and drove it for most of the day and I parked it washed it and when I went to move it, the same thing happend. I figured let me jump start it and just drive if over to my local dealer and leave it there. I checked the battery fluid level and everything was ok. This battery is only about 8 months old. It was replaced before I took delivery of the vehicle. So I doubt if it is a dead battery that is causing this problem. Something else is going on.
