Front blinkah trouble on gen2

[jackfu]

My searches turned up empty, so here goes. My passenger side front blinker on a gen2 stopped working. Got the notification message and the entire signal sequence sped up like the analog days with a burnt out bulb. Neat.
Accidentally found that charging the car at all will make the blinker work again. For a random, brief period of time at least.
Smells like a software issue more than hardware.
Thoughts?

appointment is about a month out

Possibly a dumb question, but you've tried a reset yes?

Yup cycled through quite a few times before I found the charger temporary fix. So I initially thought it was a hardware failure. But now with the charger, leaning software?

I'd lean toward a 12v issue.

Fascinating. Not the dreaded 12v replacement issue surely? On 6 month 6k miles. Wild

I had a blinker problem on 2022 gen 1 Launch Edition (this was a couple years ago). Got the rapid blink on the front passenger side. Mobile service tested all the voltages and replaced the whole passenger side headlight assembly, no problems since…

same thing just happened to me. 2025 gen 2 R1T, 3 weeks old, 1500 miles and front passenger blinker stopped working. Your charging fix doesn’t appear to be working. Service appointment for this Friday.

For what it’s worth, mine came and went for two weeks and now it’s back to working solidly… so I’m once again leaning into software issue
