This is common with Lectron's adapters. Originally they all got recalled for being too loose and potentially causing arcing when pulling them out mid charge. Now they're overcompensating and making them too tight of a fit. Some folks have even left their Lectron adapters connected to...
Can you explain what you're looking for? Are you looking for someone to create 3D models of Rivians for you? Or modify some preexisting object files for something?
Yeah, lots of folks reporting issues with SanDisk drives. If you bought it new, return it and get a Samsung T7 Shield. It's got better heat tolerance too which is important for in-vehicle storage.
Which is why I recommended asking about a mobile service appointment, or taking it to another trusted mechanic to diagnose. I'd be surprised if Rivian has some wildly proprietary AC system beyond the compressor itself.
If it can adequately cool in the shade/garage, but not in the sun/higher ambient temps then you almost certainly need a refrigerant recharge. I'd call or message Rivian support, talk to a service advisor, and ask if they can do a mobile service for you in time. If not, ask if it's the same...
I've literally started a drive with the cabin temp at 130F, full sun, and my vehicle cools just fine. Make a service appointment and have them diagnose your issue. It's a traditional AC system other than the compressor, so it's possible you just need a recharge.
That's almost certainly from the service center. I'd be asking them why it was left behind from delivery, and if there was any work done on the vehicle prior to delivery.
And how were you hooked up to the primary battery? You mentioned you were trying to jump it for a few hours, I'm assuming you used jumper cables to another 12V battery? If you've been connected to another healthy 12V for a few hours, and it's still reading 3.5V, your battery has most likely gone...
What is the voltage on the battery currently? Be very careful poking around with the low voltage system if you're not 100% confident and haven't fully diagnosed the issue.
This is a wild take. The fact there's no clock on the driver's screen with all that unused space is ridiculous. It's a clock for heavens sake. The entire control surface for this vehicle is high resolution, beautifully lit screens. There's no reason each screen can't have the time always shown...
Most folks here prefer the A2Z. I've got one and love it. Never had an issue using it.
Lectron adaptors have had recalls for not properly securing the NACS plug which allows them to release while current is flowing (bad; dangerous). The revised Lectron units have also had the opposite issue...
