Radio/tape Cd Player problems of the 2015 Hyundai Sonata

Vehicle is equipped with hands-free calling and voice access to calling located on steering wheel. These functions do not work unless the radio is first turned on. In addition, calls cannot be made from the console by pressing the phone button unless the radio is activated first - no actions occur when first pressing the steering wheel controls or the console phone button, this is a safety issue as it constitutes a distraction for the drive in any emergency situation while the vehicle is moving. There is no change in this function for a stationary vehicle. Incoming calls are automatically received to the console or steering wheel. I understand that this affects severalmodel years,.

There is a continual fluttering noise from the engine compartment which was not heard when this vehicle was first purchased. When I brought it to the Hyundai dealer to check what the noise is, the service rep, tiffany, heard the noise also when I started my engine & let it run. However, when service was completed, I was told that the serviceperson could not replicate it. This is continual and doesn't stop. I was told the engine was checked and there are no recalls for a noise of this type being issued. As a matter of fact, after they checked this, the noise was even louder and I have to keep the radio on to block it out. This is not normal. This occurs on whatever type of road I'm on and quiets down when I'm at a red light while the vehicle isn't in motion. Turning doesn't stop it. I drive on highways & city streets.

The remotes to my vehicle are defective they slide off of the valet key without the release button being pushed. Since the vehicle does not use a key to start it, will be unable to use my vehicle if the remote continues to fall apart. One of they remotes was already lost due to this malfunction and the other is wrapped in taped.

I was beginning to accelerate at a stoplight when it turned green, on a major city street, when the engine stopped without warning. The power remained, the dashboard remained lit, the radio on, climate controls on, phone remained connected to bluetooth, but the engine would not restart for 5 minutes or so. When I finally got it restarted I drove it straight home; the next morning, it restarted just fine, but I was reluctant to drive it and had it towed to the dealer. They have kept it and driven it for 150 miles since then, and nothing has happened. No error codes have shown up on diagnostics.
