Hello and thanks for the help! I have two huge problems with my 2007 limited touring and ultimate santa fe built 10/06. I have the infinity 605 watt system but do not have xm radio. Problem 1: When i listen to the radio(or cd player) at low volume levels (anything under 15) i hear a high pitched tone that is almost as loud as the radio itself. This tone is not present when i use the radio with the car off. So i am annoyed and do not use my radio. Problem 2: When i put a dvd in the rear entertainment system it starts to play the previews just fine. Then about half way into the preview it will flip over to the radio which is much louder and that is really horrible. I have to push the rse button to get it to go back to dvd. Both of these problems have been acknowledged by the service manager after 2 weeks of my car being at the dealer. In fact i sat in another santa fe that was right next to mine that had the same annoying tone and did the same thing with the dvd. I have put in a call to hyundai because they are making their service department look bad by putting their cars out this way. Since there were at least 2 santa fe's on the lot built in different years that had the same problem i would imagine that other people have noticed this. If you have noticed this please reply with what you have found out because i am tired of dealing with it and want both issues fixed. thanks Mazy |

Replying to: mazy (Jan 23, 2008 5:11 pm) What you have is the classic "Alternator Whining" problem. This is mostly audible in radio with Power Amplifier option: it has the tendency to boost the noise. When the engine is running, there is a lot of electrical noises being made. The noise could couple to the Audio system and amplify the noise. You probably hear it more during acceleration. The lack of proper Grounding, shield and Noise suppression is the cause of this type of problem. Sometime just some loose Ground cable could make it noticable. jt

Replying to: mazy (Feb 02, 2008 11:51 pm) Generically for problem like this, they have to suppress the noise source so that it does not get coupled to the Audio System. Band-aid could be adding Ground trap and/or filter to radio or Amplifier. And BTW, sometimes your add-on electronics could cause Electrical Interference too. Such things are noisy GPS module, Inverters (they are all noisy), PC. But normally they are jamming radios, not your CD. If the problem is a function of vehicle ignition on or off, then it is more likely the vehicle itself is at fault jt |

Replying to: wevk (Feb 26, 2008 4:20 pm) I've not seen any complaints of this and have not noticed it, so I don't know whether it's outside my hearing range. If this is indeed a situation where they indeed all do it, it would probably require an engineering solution on Hyundai's part. The discussion in the Edmunds forum seems to be on point. I'd expect the radio and antenna shielding would be well-grounded, so any engineering fix would most likely involve some sort of in-line filter for the antenna cable. Start with the dealer. Make them aware of the issue and have them check the vehicle. If they have difficulty repairing, they're likely to call technical assistance. If they believe it to be normal they're likely to take no further action. You'll want the dealer to call technical assistance in either case. If technical assistance tells them it's normal, there's nothing more the dealer will be able to do. Technical assistance may also propose a solution or report that one is coming but not ready yet. If the above doesn't solve the problem, make a complaint to Hyundai consumer assistance. While making the complaint still won't guarantee a fix, it'll at least make sure Hyundai is aware of the problem. The more people that call with the problem, the more likely it is that the problem will be addressed. |
