I'm right there with you. I just noticed about a week ago that mine was off. I happened to be in a blinding snowstorm, and I looked down and the reading said 68 degrees.

I was going to wait until my next oil change in a couple of weeks and have it fixed. My question to anyone who had this done, is if the dealer has the parts in stock, or did you have to 'call ahead' so they were ready?

 

Got mine done during an oil change, so not sure how long it takes, but less than 45 minutes. The dealer did not have the sensor in stock, but that was right after the TSB came out, so they might stock them now.

 

Here's the TSB if you want to read about it...

That last link was for Santa Fe.

I already had it queued up, so it was a quick post!

 

It's about a 20 min affair if they have the part in stock/
Make sure they do and if not ask them to order it and only go there once it has arrived.

 

I had mine done and they had the part in stock. I had some other things done so I left it there and picked it up a few hours later. I'm not sure how long that one job took. It's dead accurate now.

 

Now that I've been keeping my eye on it, I can see that it varies. Seems to range between 5 -15 deg F above ambient.

I just called my service center to see if they had the part, and they guy said that it might not be a replacement needed. I explained that I am looking at the TSB with the part number, and he said they might not need it. In any case he wasn't sure if they had the part.

I will see what they say when I take it in over the next couple of weeks, but if it requires a replacement part, and they don't have it I'll be a tad miffed seeing as how I tried to call ahead of time to get it straightened out.

Oh, ironically he picked my bad temperature reading out first guess. 68 degrees. He did say they are getting alot of these.

 

Update:

Taking my Sonata in first thing Monday for sensor replacement.

Stopped in a couple of days ago on my way home from work and asked the parts mgr. if they had the part in stock. I gave him the number off my TSB and he said no, they don't have one but can have one shipped in a couple of days... since I had the TSB in my hand, he said he'd go ahead and order it.

The service writers weren't around at that moment and I had a doctor's appt. to get to so I stopped by yesterday and sat down with a service writer. I told him that Will has the part on order and I'd like to have mine replaced. He asked why and I told him that it was varying 5-15 deg. F. He interrupted me and said well, that might not be enough to have it replaced under warranty...

At that point I interrupted him by saying you might want to read this, and slid the TSB to him across his desk. He said oh... well... since you have that document it will be no problem. He immediately wrote it up referencing the TSB.

What is their friggin' problem? They know it's an issue... Hyundai's more than willing to supply the upgraded part and pay the dealers to install them. This guy makes it sound like anybody coming in with the complaint, but not the TSB, is gonna get charged for it.

BTW, I learned that the part alone is $200.00. :w00t:

Yea, that part is closer to $400 up here in the great white north. They must DETEST folks like us who are informed, and up to date! You'd think that parts that have a TSB would gladly be replaced, because they know they're getting paid for it. Although when I used to repair Apple computers, their pay for that wasn't so hot. Maybe Hyundai pays them minimally too????

 

I'll be heading to the dealer this weekend to get mine replaced -- we're in the coldest stretch of the season so far in Connecticut, and Saturday afternoon, my outdoor temp began at 118 and got to 140. Restarting the car had no effect. Yesterday, after a cold start, the temp showed the accurate temp, but soon rose to 140 again -- seems to fluctuate with the engine temp and not the exterior temp. Needless to say, I'm ****.

I also noticed that when the exterior temp is super-high, you need to crank the temp up inside to get warm air. Under 80 degrees, I get cold air blowing. Is the ambient temp sensor somehow linked with the interior sensor, so one doesn't get TOO hot inside when it's 140 degrees outside (for example)??

Needless to say, I refuse to turn the interior temp higher than usual, just to compensate. For me, it's the principle of having a [relatively] new car with a problem. My fiancee is not too thrilled with this...

 

Got my temp sensor replaced this morning and all is now well.

And yes, the climate control does use data from the outside temp sensor. With my temp sensor always reading high (5-15 deg.), the climate control would work but the fan would always run slow in the auto mode... even when it "needed" to run faster.

Now, with the correct ambient temp. data being supplied, the auto climate runs the fan fast and gradually reduces fan speed as the cabin temp increases.

Much more better best! :thumbsup:

Mel

 

Sorry to hear all you folks having troubles, Im glad I have the po' heat controls now.

 

It's amazing how much better the auto climate control "system" works when all of it's "components" are working properly.

Well, this temp sensor (a known issue) and the replacement of the fuel tank level sending unit (another known issue) are the only things I've taken the car back for.

Hopefully, my Sonata and I will now have a long and happy relationship.

I just pray that the timing chain guides/tensioners/whatever-they-are don't go TU on me. I really don't want to see them have to yank the entire engine out of my car. :crying:

Been there, had that done for a different reason.

The car runs the same or better than it did before.
As long as your dealership has competent mechanics, dont fear the engine pull.
