Tiburon BCM Failure turn signal stays on
 

:mad:

As some of you know, a common problem with Tiburons is that Hyundai installed faulty relays in their BCM / Body Control Modules. After a while you will notice that either your left or right blinker "sticks" and will stay on, whether the car is on or off. One would think that you can just change the relay, but it is not that simple. You have two options, the first being to take the car to a certified dealer and pay over a thousand to have the entire BCM replaced. The other option is to determine which is the faulty relay on your own (good luck), find and obtain the correct replacement relay (good luck), and have them switched. This is much cheaper, but if you burn the board in the process, you will be out of a BCM.
Now like me, you are probably wondering how Hyundai did not put out a recall on this issue. The answer is because no one is calling them and filing formal complaints, according to them. So everyone who has already paid to fix it, or is currently experiencing this problem needs to call up Hyundai USA and file a complaint, they will give you a case number, etc. If enough ipeople call in they will do a recall on the part, or if you have already paid, you will be reimbursed for the full amout for the repair. They seem to think that this is not a common issue. Just call them and give them an earfull. Thanks for your time and good luck

I searched around for a while, but I was not able to determine which relay it was either. If you go to car-part.com, you can search around for wrecked cars in your area and go to a junkyard and just purchase ALL the relays and try to find it that way.

Default RE: '03 Turn signal problem
That's acommon problem for Tiburons. It's not the stalk, it's the BCM (Body Control Module). The BCM controls a bunch of different things including the turn signals. The problem is a relaythat has gone bad. Unfortunately, the relay is not removable. It must be unsoldered to be removed and a new on must be re-soldered back on.

If the car is under warranty, take it to the dealership and have the whole BCM replaced. If it's not under warranty, the BCMis a $500+ part to replace new. You can either try to get a used BCM from a junkyard or you can try to replace the bad relay one your BCM if you are good at soldering on an electronic circuit board.
