Right turn signal stays constantly glowing out of no where. Turned the left signal on and the right signal came on as well and stays on even when the car is off. It doesn't blink it just stays glowing. I have read numerous reports from mechanics and other driver with the same vehicle that the relay inside the BCM tends to go bad. If it were just a fluke and it was just mine that was bad I would cough up the money and replace it but if I find numerous people that have had the same problem then seems like Hyundai has a faulty part and it needs to be fixed, and also funny how if you order the module on the circuit board that needs to be replaced the part number has changed because they have updated that module so they must have even found a problem with the module. Seems like a safety problem as it confuses drivers around me because my right turn signal is constantly glowing then all the sudden left turn signal is flashing.

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. Hyundai would not cover the repair because the car was out of warranty. There is nothing a consumer can do to "maintain" a body control module and Hyundai should be held accountable for this safety issue.

My 2004 Hyundai Tiburon suffers from a long list of electrical problems. Both power window motors have stopped working, my power trunk latch is defective, the interior light switch doesn't work, and now the turn signal relay that is part of the body control module has caused intermittent problems with my left turn signal. Sometimes it stays on even after turning off the car. I'm worried I may be rear-ended because although my signal is on, it sometimes does not flash properly due to the faulty BCM. Research indicates these are very common issues with Hyundai vehicles, and very expensive to repair. The BCM is about $700 alone. The window motors are about $300 each. It is ridiculous to pay $700 for a signal light. Hyundai should be held accountable for shoddy engineering!

The blinker light remained constant and drained the battery. The body control module needed to be replaced at 80,000 miles at the cost of $1200!!
