  1. R1 Gen 3 - Wish list

    For those that don't know, solid state batteries use a combination of polymeric electrolytes and liquid electrolyte. They are safer, because there is less nasty liquid. The plates (electrodes) can be spaced closer to each other, to reduce the physical size of the stack; he gravimetric density...
  2. Climate pre-conditioning from the app

    I'm guessing that the internet connection goes to sleep after a while so the cabin temperature is not being updated. You can try waking the car. That usually fixes it for me.
  3. Rear 12V Harness Voltage Check

    The clue is that your DVM automatically switched to ohms. That tells me that your meter was in the auto mode rather than the dc Volts mode. In the auto mode your meter presents a load of about 2 K Ohms at the test leads rather than 10 M ohm. There is a diode or something in the jumper circuit...
  4. Insulate Your Glass Roof - Improve Comfort, Efficiency

    People tend to overestimate IR rejection. Visible light from the sun causes significant heating too. When the interior surfaces heat, they radiate IR.
  5. Insulate Your Glass Roof - Improve Comfort, Efficiency

    I have a feeling that the glass roof (without electrochromic glass) may be less expensive to manufacturer than a steel roof. I could do without it. I had tinted windshield protective fil applied to the outside of mine--R1S. I had very dark tint for the rear roof. Of course, it doesn't do much...
  6. Anti-EV agenda

    I did not loose out on the tax exemption for my new gen 2 R1S Quad Launch Edition. It cost too much to qualify. There was no incentive for buyers of these cars.
  7. Driver’s display question

    Driving along the pacific coast from about Malibu to the border with Mexico, there are many beach towns that run together. The town changes every few miles. Worse, the street address numbering resets.
  8. 2025.46 Do Not Attempt Digitsl Key Setup Unless You are Sure Your Phone is Compatable

    The problem has been fixed. Engineering reverted the key portion of the entry code to the previous version by pushing change to my vehicle. I then followed the steps to set up my phone as a (Bluetooth) key as in the previous version. Everything works now; except I cannot set up a digital key--I...
  9. “Not One Single Percentage Point” of Degradation" - F150 Lightning charged to 100% every night

    I concur. One apparent cause of battery degradation is storage for long time periods at a high state of charge. In other words, the capacity of a lithium ion batterie's capacity will degrade if it fully charged, then left alone for awhile. This observation has led to dubious beliefs, like...
  10. Auto high beams with fog lights active

    My 2003 MINI Cooper had rear fogs. All of the cars had the lamps and wiring installed, but the switch to turn them on was an option. It could be dealer installed by replacing the center toggle switch assembly and enabling them in the firmware. BTW the rear fog lights would cancel when the...
  11. “Not One Single Percentage Point” of Degradation" - F150 Lightning charged to 100% every night

    Another reason for not charging to 100% is patience. The charge rate slows down when the battery SOC reaches somewhere between 70% to 90%. The last 20% charge can take as much as half as much time as charging from 20% to 80%. Of course, this more of a noticeable problem with DC fast charging...
  12. Solution: Passive Entry Via Bluetooth Not working

    I tried that. Now nothing on the app works. Customer service is stumped. I have a mobile service appointment for next year.
  13. Can anyone share their experience with installing a Rivian Compact Spare Kit at the Rivian SC

    I told my delivery specialist in advance that I wanted that I wanted the spare. After the delivery was complete, they filled out thr service ticket and whisked my new launch edition info the shop. I hung around the waiting room for less than 15 minutes before my R1S lwas parked out front again...
  14. UHF doesn't switch lanes with signal on non highways?

    That's my experience also. I find that I can use the steering wheel th change lanes without causing UHF TO disengage.
  15. Main display cover art resolution

    Album art does not necessarily come from the streaming app. Some apps look up the album on a seperate server to display the cover art.
  16. Universal Hands-Free can kill you! (If you don’t read release notes)

    I was an engineer for a medical gadget company. Regulatory agencies do not allow statements in the user's manuals to be used for mitigation in required failure analysis (FaMICA). Actually product labeling, either. Everyone knows that when hospitals unpack the devices, the first thing that they...
  17. 2025.46 Do Not Attempt Digitsl Key Setup Unless You are Sure Your Phone is Compatable

    Some information on digital communication technologies that might be helpful: Bluetooth uses radio waves in the 2.54 GHz license free Industrial, Scientific, Medical (ISM) band, which is also used for things like Wi-Fi, microwave ovens, and medical telemetry. It uses frequency hopping...
  18. 2025.46 Do Not Attempt Digitsl Key Setup Unless You are Sure Your Phone is Compatable

    I checked on the internet, the Z-Flip 3 phones do not have the necessary UBW chip and antenna. They do have support for some UBW features but they lack the the hardware. The Z-fold phones do. Perhaps thats the confusions. The Z-flip phone es did not get a dedicated UBW chip until later. Tap...
