I’ve been doing some research on the GM part number 85090442, which is associated with the NACS (North American Charging Standard) adapter aimed at connecting GM electric vehicles to Tesla’s Supercharger network.

I drive a Chevy Bolt and have been looking for ways to enhance my charging options, especially since the number of compatible fast chargers is crucial for long-range travel. Here’s what I’ve found so far, and I’d appreciate any insights or experiences you might have:

  • Compatibility: I’ve read mixed things about compatibility between different GM models and the adapter. If you have personal experience or know anyone who tried this with a specific model, please share!
  • Availability: I’m concerned about how easy it is to get this adapter. Is it readily available in dealerships, or do we have to order it online? Any tips on where to find it would be super helpful.
  • Charging Rate: Does using this adapter affect charging speeds? I’ve seen varying opinions on this, and it seems important to know how it may impact charging efficiency.

Questions I Have:

I definitely experienced that too! I found that using a heat gun helped to soften the adapter slightly for a better fit. Just be careful not to overdo it!

I’ve been using the adapter for a couple of weeks now, and performance-wise, it seems fine. However, I do notice some occasional flickering in the dashboard lights when connected. Has anyone else noticed this?
