"What An Experience"!!!!

[Soldier76]

So my TPMS light was coming on for a few months on my Genny, so I finally took it to the dealership (after I kept filling that same tire up every 4 or so days). When I get there the mechanic tells me that I have a flat. Not only can't they patch up my tire but need a whole new one, because the nail was in a place where if it was patched up it would just leak again eventually (atleast that's what the mechanic told me).


So after about 5 hours I came back to pick up my car and pay $199 for a sports tire, I found that my rim was severely damaged. I showed the mechanic and he assured me that whoever changed the tire will pay for the rim out of their own paycheck (which was $467 btw). So now I have to bring my car back in that following Monday.


On the way home about 30 minutes into the ride the TPMS light comes back on again. At this time I know I shouldn't have a flat so I figured it must be something wrong with the electronics. So the dealership gets a call from me first thing in the morning about my issue. I soon find out that my headlight units have to be changed out also because they supposedly get real hot and causes the TPMS to go crazy. So we arranged for all of this to be taken care of that monday when my rim was supposed to be replaced.


I arrived at the dealership on monday the head mechanic told me that the car needed to stay overnight and provided me with a rental from enterprise (a 2010 Hyundai Sonata). The Sonata AC really really really sucked compared to my Genny but the ride was better than my 08 Camry. Anyway the next day I picked up my car with my new rim and complete headlight set, and is satisfied with the way the dealership took care of me. I just Hope that things go well with these headlight, I'll keep you posted.

I'm glad everything turned out good for you. I've had good dealer experiences lately as well.

I'm SOoo glad I dont have the TPMS system on my car. Of course the downside is, if I get a puncture by the time I notice and get the car stopped, my tire will be toast anyway.

Glad it all turned out OK for you.

Why are you glad you don't have this feature? I have it on my Lexus and a slow leak around the rim, notified me and probably saved me a tire blow out.

I understand your downside; what is the upside?

 

[Soldier76]

I'm really Thankful that I had this car for a year and a couple months, and this is the only minor issue that I had.

I am also glad I do not have it either. Had it on a Murano several years back and what a pita. Here in Canada we get cold winters. On very cold mornings I would get flat tire warnings due to the temp effect on pressure. I had to keep my pressures at least 5-8 lbs higher than recommended to avoid these warnings during the winter!!! If they were smart, they would correlate between exterior temps and pressure to avoid these stupid false warnings. Great system if you live in warmer climates though. Maybe this is why they do not come with the Canadian Genesis model?

I too had intermittent TPMS issues. I have the base V8 model 2009. The headlight assemblies were replaced a few months ago, and I have not had the problem since. I did notice that after washing the car a few times that there was headlight condensation. Initially this disturbed me, but after about a month, the problem went away on it's own. Keep an eye out for it.

I thought all Genesis' have (and must have) the TPMS, not just the 4.6 Tech. Am I wrong?

Basically the same reasons described by 'MidnightSun'.
I had a bad experience with TPMS on another vehicle giving false readings. It was also a PITA when I tried to put non-stock tire sizes on the stock rims.

To the best of my knowledge none of the Genesis sold in Canada have TPMS.

My 2010 4.6 with tech does. So far no problems with it but I haven't gone through a winter with it yet.....

 

[CanukV6]

What winter? You live in Vancouver!
Maybe they started fitting TPMS for the 2010 models in Canada.

 

[fperra]

All cars 2007 or later cars sold in the USA are required to have TPMS installed.

Thats what I thought. All Genesis' have TPMS. As for the TPMS lamp coming on in cold weather, so far, mine have not come on. (Yes, I'm "mostly" in Florida but I'm KNOCKING ON WOOD).

Before I drove to Roswell last December, knowing it was going to be COLD out there, I pumped up my tires to 35 or 36 lbs, knowing that the pressure would come down in the cold. The temperatures in Roswell were mostly in the mid to low 20's at night, and high 30's low 40 in the day. I did see one morning when I started out that the temperature was 11F. Yes, 11F is COLD, but even then, the TPMS lamp did not come on. (still knocking on wood).

Also changed my tires a couple weeks ago, and even then, TPMS lamp did not come on, just as my Genesis Technician said.

When the day comes that the TPMS lamp comes on, I'll know that it is a serius problem. (again, knocking on wood).

I heard filling your tires with nitrogen is suppose to alleviate all the problems with the temperatures changing the pressure in the tires. A couple of salesman from Toyota and Hyundai told me that if you put nitrogen in your car tires, you wouldn't have to worry about filling them up for a couple of years. one of the salesman also said that you have a lesser chance at getting a flat also. Don't really know too much about any of what they told me, but would like to know if nitrogen is expensive?

Ok - so, unlike mere ordinary air, nitrogen does not leak out, and it puncture-proofs your tires? If that's true - and how could it not be if a salesman said it? - I'm gonna get me some! If The Sharper Image were still around I bet they'd carry it. Maybe Hammacher Schlemmer will deliver some to my (garage) door (for a small fee, of course)...

If you live in say a desert climate, there can be 30 degree temperature swings between day and night. This will also swing the pressure in your tires as well. Nitrogen is not affected by the temp swings, so in theory it's a good idea. It has zero affect on getting a flat or leaking out of your tires. I think the last place I checked it was 10 bucks a tire. At the end of the day it probably isn't worth the money.

I had nitrogen in the tires of my Genesis, and it has been a nuisance. Every time we had a cold spell, I had to take it back to the dealer becuase a tire pressure indicator came on. I got tired of wasting an hour or so every trip, so I finally just went to a local service station and topped it off with air. No more wasted trips to the dealer, and no more problems with pressure indicators.

 

[MrB0462]

Nitrogen as stated by others is not affected as much by tire temp changes. For that reason it has become normal for race cars to use nitrogen in their tires.

For street use it is expensive and if you need to add air you are diluting the nitrogen unless you buy a nitrogen filled storage cylinder. Yes you may have to add more at anytime as a leak may develop.

I wonder if it will cure cancer after preventing leaks/punctures/etc.

Normal Dry Air filled tires are as stable during big temperature changes as Nitrogen. Air is 78% Nitrogen, 21% Oxygen and 1% other gases. The reason that air filled tyres often change pressure so much with temperature is that the air used is rarely totally dry and any significant degree of humidity in the air will cause pressure changes with temperature. Tires filled with Nitrogen that we will assume is always dry (since it comes from a Factory filled 'bottle') will remain more stable than most compressed air that will usually have some water vapour content. The problem comes when you have to add "air" to the tires and introduce water vapour in the process. Then you are no better off than regular compressed air.

The pitch about never needing to add air with nitrogen filled tyres and being less likely to have a flat is all built around the premise that you have zero leaks from your tire due to rim corrosion or faulty valves. Nitrogen molecules are larger than air (or at least 22% of air) and the theory is that they are less likely to seep out through the tire structure than regular air. Nitrogen has no advantage in terms of a punctured tire. Another perceived advantage is that the 21% oxygen in compressed air will attack the tire compounds over time causing degradation, unlike nitrogen which is inert, although you can be sure the tread will wear out long before that becomes a serious issue.
