2004 Hyundai Tiburon Electrical system Problems

“I have a 2004 Hyundai Tiburon gt. While I was driving and switched it the right turn signal, it would not turn off. I pulled over and was unable to get it off. Even after shutting off the car and removing the key, the turn signal remained on. The only way to turn it off was to remove the bulbs front the front and rear headlights. I took the car to a Hyundai dealership and said the body control module failed and needed to be replaced. The cost to replace was $1,280. Upon researching this issue online, it appears to be a common issue in 2003-2004 tiburons from Hyundai. …”

“Almost right after purchasing the vehicle, I started experiencing electrical problems. The alarm system would randomly go off and sometimes even lock the doors of the car on it's own. Whether the car was running or not, windows open or shut, did not matter. Later the windshield wiper motor burned out so only the fastest setting works and only when I hold the knob up for the one time wipe. The window motor went out on the passenger side as well. If you were to slam or hit the door, the window will roll down, but not back up unless you pull very hard on it to get it going. …”

“I bought my 2004 Tiburon in july of that year, and had to get rid of it (even rolled the loan money over), in 2006, I hated it so much. The paint chipped off all over the car, the seat color was wearing off, the dashboard color wore off, the lights on the radio went out. Of course not one of the issues were covered under the great warranty the offer. My sister got the same car, she had her automatic/manual shifter go, her tires were completely bare after 2 years, her gas cap paint came over, down to the metal. This was the worst car ever made.”

“The contact owns a 2004 Hyundai Tiburon. The contact stated that the turn signal switch did not function when the left turn signal was turned on. The battery failed to function properly as long as the turn signal fuse was in the vehicle. The manufacturer was notified of the failure and stated that the body control module needed replacing. There were no repairs completed on the vehicle. The failure mileage was 119,000 and the current mileage 122,000.”

“Hyundai know about an issue with their electrical system affecting the air conditioning on their tiburons, but have done nothing about it. It is when you select higher speeds of A/C, the connector behind the dashboard heats up so much, it melts the connector and causes the A/C to fail. Hyundai doesn't cover this under warranty or recall. They make me buy another switch. But the problem still exists, causing the replacement to fail as well.”
