Turn Signal Problems of GMC Sierra 2500

Right rear turn signal bottom socket heats up and causes an open to the top turn signal socket so the top turn signal quits working and causes the system to hyper flash. And indicate inoperative right rear turn signal in message center. Only repair is to replace wiring harness and sockets. System works fine in cold temperatures as the socket does not heat up enough. Happens with vehicle stationary and in motion. Contacted gm about it and got nowhere.

Drivers side, in-mirror (with extendable, manual, trailer mirror) turn signal too bright or should be shielded from drivers eyes. Blindingly bright for making left-hand turns. Problem worsens as ambient light is reduced.

I have the tow mirrors and they have led lights in the mirrors for blinkers and they are extremely bright! when you use your turn signal at night they are so bright that they make it so you can not see on coming traffic very well from the sides of the pickup while at a intersection or when you are trying to change lanes. In my opinion this is extremely dangerous. The blinker leds should not shine directly into the drivers eyes.

My wife was driving her truck to dialysis appt at 6:00 am when she heard a noise and her left outside mirror exploded spraying the left door glass and side of the truck with glass and a gel.
