exhaust rattle, A/C annoyance
I have a 2010 Touring. It's 10 months old. Overall I like the car quite a bit. It recently developed an exhaust rattle that occurs when the car is accelerating. It's loudest between 35 mph and 40 mph. Anyone else have this problem? This is the only problem I've had so far. I'll be bringing it to the dealer...
A/C annoyance: this is the way the car is designed and I hope Hyundai will change it. If I turn the defrost on, the A/C comes on automatically. I'm ok with that so far. However, if I press the A/C button to turn the A/C off, the indicator light goes off, but the A/C still runs! There is no way to shut it off. There are only certain weather conditions that require the A/C to be on when the defroster is on. It does this whether it's full defrost, or the defrost/floor vent split setting. I hate it when cars try to do too much of my thinking for me. Hyundai, please change this. If someone wants the A/C off when the defroster is on, it should actually go OFF when you turn it off!

I didn't bring this up because I thought it was abnormal. I brought it up because, as I said, it's an annoyance. I'm fully aware of what the A/C does with the defrost. I only brought it up because I think there should be a design change. And, no, you don't need the A/C on whenever the defrost is on. I drove a car for 12 years that had no A/C at all. It's only necessary in certain weather conditions.
The car is thinking for you because it knows more than you when it comes to this topic.

The rattle you discribed sounds like the resonator tube. I had the same rattle and I have heard of other people with the same problem.

As I said, I drove a car for 12 years (and another one for 5 years before that) with no A/C. 80% of the time it defrosted just fine. A/C wouldn't have made that 80% any better. Besides, why difference does it make to you if the switch works by choice? You can leave yours on all the time, and I can turn it on only when I want. It affects your life not at all.

And with A/C it would have defrosted 100% of the time even better than without.
Why would you purposely want to defrost SLOWER without A/C? What reason do you have against having the A/C run and making the defrost work better? Running the A/C keeps the compressor lubed year round and costs you very little in fuel economy. The little amount of time it runs in the winter does not affect fuel economy.
