  1. Seized rear calipers - Rivian stuck me with the bill

    Is there a guide to greasing the pins somewhere? Any recommended grease?
  2. Seized rear calipers - Rivian stuck me with the bill

    Sorry I have had a brake pad video loaded into final cut for editing for...6 months and still haven't got around to making it! I replaced my rear inner pads this summer, and it looks like I will need to replace them every single year. The inner pads wear fully while the outers are still good as...
  3. R1T Limited Regen Warning: What's normal?

    I do a regen braking test every single day as my commute is a continuous 5 miles downhill, repeatable in all conditions. I've continued to learn more details. Remember regen is the same as high-powered DC charging, pushing 100-200kW into the pack. Similarly, the pack will refuse to accept it as...
  4. Seized rear calipers - Rivian stuck me with the bill

    No idea if they greased anything. I have made every conscious attempt not to use the brakes, and brake assist is disabled. I don’t drive in stop and go traffic. I give the brakes just one good squeeze each morning at the bottom of the hill thinking it might help move calipers otherwise they are...
  5. Seized rear calipers - Rivian stuck me with the bill

    I’m back, as the problem has returned IN LESS THAN A YEAR after Rivian charge me over a grand for new pads and rotors. Just 15k mi and inner pads are again worn, squealing, and I even have pulsating braking. There is no way this is just normal wear. Has anyone had success with rivian looking...
  6. Interior passenger-side fuse box

    Has any ever found an add-a-fuse for the larger MXC fuses? I still would prefer to tap one of the accessory socket fuses over the mini ones.
  7. Rivian Space to open right above Massachusetts Turnpike

    Holy crap. Definitely did not see that coming when first thinking of the Pike air rights space! Think of folks seeing the Rivian sign every day. As for your VT comments, it’s definitely the perfect match for a VT vehicle, if only it weren’t for the service debacle. I might insist on service in...
  8. Seized rear calipers - Rivian stuck me with the bill

    Can you provide a little instruction and photos for that? I'll start doing the same
  9. Seized rear calipers - Rivian stuck me with the bill

    For the record, I had pretty much the same thing. Rear wheels screeching on and off like a junker driving around. Checked outer pads with wheels removed and they looked nearly a CM, so told service to see what was up. They said my inner pads measured 1mm, and I had to pay to replace all four...
  10. Camp Speaker Curiosity Teardown ?

    Thanks for posting. The Camp Speaker is clearly way overengineered for what it is, and makes me think they intended so much more for it. Thundercomm is a chinese Qualcomm offshoot that makes SOCs out of QC processors as well as development boards for QC. The TurboX C404 is made for a very, very...
  11. Vermonting Vermonters

    Hi folks, I'm starting to look at the Vermont DMV info for moving registration over, and there are so many confusing questions. It was asked before her, does anyone understand the truck and fuel classification? Can anyone see what weights and fuel rivian put on their DMV form? It seems to me...
  12. Got a Model 3 (Jun 2023 build) rental while my R1T in service…

    Thanks for pointing that out, I do very much miss the Model 3 pedal, Rivian has way too much dead zone and unresponsiveness.
  13. Got a Model 3 (Jun 2023 build) rental while my R1T in service…

    Interesting perspective, haven't driven the 3 since I traded my 2018 for the Rivian as well. I assume I will love the sportiness as I did before, but I bet it will feel much slower!
  14. R1T Limited Regen Warning: What's normal?

    This is the point. It's charge rating of the cells and chemistry. Most have a much higher C rating for discharge than charge. It's got nothing to do with temperature at normal temps. Rivian is just playing it safe and trying to track and limit how quickly energy goes into the cells, and is more...
  15. MA Glass replacement

    How large is the crack? Crack needs to be dollar-bill sized in length to cause any issue for inspection, and replacement is super easy in Mass if you need to But if it's just a chip don't even worry about it.
  16. 120V Inverter Teardown

    Very interesting he mentions in the video he claims Rivian is running 3 in parallel, and he plans to run 2 in parallel. Not only do I wonder what is needed to run them in parallel, but also I wonder where he got that info, and perhaps was Rivian originally planning to have 3 for more power...
  17. 120V Inverter Teardown

    Wow, thank you for tearing this open for us! First, this does not look like Rivian's design at all, it is all older tech inside. I couldn't see any branding on the PCB or elsewhere, could you? Do you have any better/closer photos of the PCB? It also appears to be smaller than the area...
  18. R1T Limited Regen Warning: What's normal?

    Sorry for the delay, here is new data, taken at 50% SOC. As you can see you get a few more seconds before it derates, but more significantly it seems to derate to 200A instead of 75A limit. Similar to when you're DC charging. I also included IGBT temps, which stay reasonable. Again if motors or...
  19. R1T Limited Regen Warning: What's normal?

    Put it this way, it's not motor or inverter temperatures, or your acceleration would be limited as well. If the inverter were too hot, it's generating heat no matter which way it's generating torque so both your regen and acceleration would have the same 70A limit, and that is most definitely...
  20. R1T Limited Regen Warning: What's normal?

    I logged going down my hill yesterday, left a room temp garage at 75%, there's a bit of uphill to the road so it's at 73.6% user SOC at the top and only rises to 74.6% after this ten minute downhill drive. Have a look at all the data, but to me it's just safe software limiting in the BMS, and...
