Tail light / turn signal malfunction

[bobaurora]

Wondering if any one has experienced this.

First when I activate the left turn signal I get a fast blinking and only the front one blinks. Second I have noticed randomly that I will go somewhere or walk out in the garage to see that the left rear taillight is on. Just the one taillight. Then it randomly turns off. I can't make any sense out of when it decides to do this.

Anyone experience this or have theories? Seems like something besides a bulb since the light works it just won't blink.

I did try a full reset.

Service ticket has been filed.

Sounds like something faulty with the left rear light assembly where you truck thinks the rear left signal isn’t working so it hyperflashes like in other cars when the bulb burns out.

My guess would be that they would need to replace that assembly or see if there is some wiring issue.

Just closing this one off with what was fixed. They replaced the entire taillight assembly, the service experience was excellent, it took a couple weeks for the appointment.
