2016 Stock Denali hyper flash

[whaler]

I see a ton of fixes for tail light swaps. Has anyone had issues with hyper flash on stock LED tail lights. Dealer wants to replace a board for $1 k. Help

What board are they referring too?

 

Should have no issues with factory equipment, but are you still on the original battery?

[whaler]

Yes, original battery.
Stock controller board I guess?
This is driving me nuts with flashing thing.

1k? Sheesh, you can get a entire set of OEM LED tail lights from @Frankielozano214 for under $500 shipped. My guess would be the resistor went out. Does it only hyperflash on the 4th blink or right away when you hit the blinker? 

[Frankielozano214]

Yup usually sell set for 480$ shipped with oem led harnesses to beat my competitors prices

I don’t think I have any issues with the tail lights.
They work fine and are in great shape.
My left rear will hyperflash after 3 blinks.
Sounds like a resistor? Where would that be found? Thanks for the help!

Did your truck come factory with led taillights or you added them? If you added them resistors would be by the spare tire (follow the harness behind taillights to underside of the truck by the spare) usually resistors are orange copper color

Stock Denali with LED tail lights. Other side works as they should.

Likely a failed tail light.

Well called my dealer and got a quote. $925 for a left tail light. Crazy
