Radio/tape Cd Player problems of the 2009 Hyundai Santa Fe

I purchased this car used in 2011. Over the years, at random times, the radio will "pop" off and back on again. It doesn't seem to affect the rest of the electrical system in the car, but it's a little scary when it happens - mechanic can't replicate. Now, twice in the last week, my car has stalled while slowing down, once on a multi-lane street and once after decelerating coming off the expressway (complete loss of power, steering, brakes, etc). I put the car in neutral and it started right back up, but this has happened in heavy traffic and scared the p out of me! I'm terrified that this might happen at a higher speed on the expressway. I have seen several mentions of similar power losses for this same vehicle. I have no check engine lights and no codes come up when scanned. No recalls reported either, although a power loss at the wrong time could kill someone. Not sure if this is electrical, engine or fuel system related - I had over a half a tank of gas in the car during both occurrences.

On 01/02/2010, I bought a Hyundai Santa Fe limited from a car dealer named southern states imports in raleigh. A few days later, I noticed that the front seat passenger airbag off red light stayed on occasionally regardless of the weight or position of the front seat occupant. Around the same time, I noticed that the cd player occasionally automatically tripped over to the radio and vice versa. I called the dealership and received conflicting advice on what I should do at this time. However, I chose the advice of my first contact person at the dealership and decided to wait until either or both my complaints occurred again. Two days after this decision, the airbag off light did not go off as I was traveling to downtown raleigh, nc. The next morning, I noticed that instead of the entertainment center opening to a cd music set (since it was last on cd), music from a radio station started playing. The next day- Monday, I dropped the car at the dealerships service department. After 2-3 days of testing, I was asked to pick up my car and told they were unable to duplicate my complaints. Both dealership and USA Hyundai advised me to bring it into service as soon as I notice either complaint happening again regardless of time. A few days later (2-3 days) the same complaints (airbag and radio problems) re-occurred and I dropped the Santa Fe at southern states Hyundai dealership service station with one of my sons at about 10. 15 p. M. Ofcourse, I have been informed by both dealership and us Hyundai that they problems could not be detected or duplicated. As a result of the above problems, I have no confidence to drive this particular Hyundai and the car in question has remained in the hands of the southern states Hyundai dealership and/or service department.

Continuation of complaint 10302521. Since last service dept visit, dvd player worked fine for approx. 2 months. Now in July 2010, dvd player is back to switching to xm at random at least 1 x wk and up to 1 x day. Mostly after bumpy rds. But service dept refuses it is a loose wire. They have continually stated they do not want to tear apart steering wheel even though that and the actual player are the last areas not replaced. Srvce dept stands by intertwining radio signals, then why is it switching to xm and not picking up the random signal. Feel like I have to live with it. Srvc dept again suggested I leave car so they can search again but no guarantees. Does anyone know if there is a fix.

Hyundai Santa Fe purchased on 12 sept 2009. Dvd screen not functioning, could hear movie not see it. Dealership replaced screen in October 2009. Since then, the dvd rse system has intermittently changed from dvd to xm or cd at will. Rear passengers are not able to reach the dvd buttons due to age and child safety seats. Rse is locked from front controls. Dvd system continues to switch from dvd to xm or cd at least once per day causing the passengers to be blasted with high volume music. In October 2009, the internal electrical control system (for doors and windows and such) was replaced and the alarm system was reset (it kept arming itself randomly). In November 2009, the alarm system was reset again and the dvd problem was brought to mechanics attention again. Alarm system was fixed but they could not replicate the dvd problem. Took car in again 16 January 2010, was told intertwining outside radio signals and the fact I work on a military base were causing the dvd to switch. Ft sam houston, TX is mainly a medical training military base. Mechanic replicated problem but later told shop manager that he couldn't replicate the problem with out driving in town where I normally drive. Mechanic and repair shop manager stated it could not be a loose plug or wiring it was the radio signals. This occurs at random and I thought it was from bumps in the road until it continued to happen when driver was not touching the steering wheel or radio controls, at stop lights, and on smooth roads. I researched this problem and found a blog on edmunds stating Hyundai has know about this and audio problems since 2007 but nothing will fix dvd problem.
