AGAIN! No Audio AGAIN! I'm so friggin tired of this! As I left work today there was no audio. I drove directly to my Hyundai dealership so that they might witness and make a record of their malfunctioning product. I am on the third Head Unit now (the initial one and two replacements) and my dealer is ordering another.

I called Customer Service this morning to have a case opened. I gave them the list of issues with my now year and a half old car (namely bad head unit, bad fuel injector, bad cruise control, bad door lock actuator, bad idler pulley, bad steering wheel positioner...)

I'm very, very close to being done with Hyundai. This has been an unhappy and expensive experience. The thing is that when this car is working I'm very happy with it BUT these problems and resulting visits to the dealership are wearing me thin.

Out of curiosity, have you replaced the battery? I ask because many BMWs from the mid-90s displayed odd, seemingly unrelated symptoms with an aging battery. This included no audio. The tough part was that the battery would start the car fine. It would also pass a load test. But the battery was definitely the cause. I wonder if the Genesis has a similar phantom cause. If I had a Genesis doing this, I would buy a new battery just to see if that made a difference.

I have never replaced the battery...yours, GenesisCaptain , is the first reference to the battery as the cause. I'll mention this but I don't believe my input will have any effect on the "master mechanic" who is in touch with Hyundai engineering (as reported by the service writer) about the issue.

The Customer Service contact "has never heard of any radio issues"....riiiight!

Last Friday, I too have had the infamous radio problem. Restarted the car several times and to no avail, radio didn't work. Finally came home and looked on this forum and read this thead. Went back outside to start the car and the radio started playing.

It could be a key fob issue? Have you tried replacing the batteries in the fob?

I give 0% odds the master mechanic will replace the battery. It won't make any sense to him. It did not make sense for most of the BMW enthusiast community until we started seeing many cases on an active forum and the battery fixed nearly every one.

I bet it is a power problem and not a head unit problem-- the odds that you got three dead HUs with the exact same problem is exceedingly rare. Either the battery has a bad cell, or there is a poor ground or poor power connection that relates to the A/V system. If it is a battery, it will be an easy fix. If it is a ground problem, it could be very hard to find and fix.

See if you can persuade the mechanic to put a voltmeter on the amp and HU. That is not a perfect test, but if the two are not the same and not the same as the voltage measured across the battery terminals, that could indicate a cause.
