After going down the rabbit hole on dozens of other threads on the 12v topic on various forums the past couple of days, I’m still at a loss and have not found another with identical symptoms/issues, with no advanced warning/alert, so posting in case anyone finds themselves in a similar situation to mine. Here is the timeline/situation:
April 2024 (~7k miles): I go out to my car in my garage one morning to find it completely dead/unresponsive following an OTA update the evening before. Mobile tech comes out the following day and explains a lot of owners have experienced 12v battery failures as a result of the recent update. New 12v (my R1s has single battery) installed, systems diagnostics run and everything recalibrated. All is good again.
Thanksgiving (7mos. later; ~14k miles): I arrive to my sisters ~40miles from my house that morning with ~80% SOC. I go back out to my car to grab something an hour later and notice the car was unlocked and completely dead/unresponsive. I call Rivian support and they have me try a variety of different resets (frunk button 10x, soft and hard reset) but car remains unresponsive. I suggest to support that perhaps jump starting might fix and they responded that they did not receive any diagnostic info prior to the vehicle dying that would lead them to believe the 12v battery was faulty and wanted to arrange a tow for the next day. Despite this, I jumped it with my wife’s car later that afternoon and was able to restore the vehicle to a functional state and drive it home. Updated support that I was able to get the vehicle home and requested a mobile service appointment ASAP to try and diagnose what was going on.
11/30-12/1: Hesitant to use vehicle but do on 2 separate occasions on errands close to home and vehicle operates normally without issue.
Tuesday 12/3: mobile service comes out and explains that my vehicle was flagged internally on 11/9 as having one of the defective 12v batteries installed so he came to replace. Replaces 12v, runs diagnostic, resets and recalibrates everything. Within 5min of the service tech leaving, my vehicle is completely dead again. I try jump starting again which wakes the vehicle up and boots up the computers but immediately dies again after I remove the jumper cables. Text mobile service rep to let him know and he says it’ll have to be towed to SC…he’s out of ideas as voltage on 12v was confirmed good and all other diagnostics were fine.
12/6: Rivian towed out of my garage to Richmond SC. Because of backlog and “nature of the concern” they likely will not get around to my vehicle until the new year, per the SC rep.
Thanksgiving was my first time feeling a bit of buyer’s remorse with my Rivian. It would be one thing if it was a clunking CV axle or excessive wind noise but feeling like this vehicle has a high probability of leaving me stranded - without any sort of advance warning - is something else altogether.
Reading through other threads with similar recurring 12v system issues, I’m leaning toward this being a fault with one of the control modules or the HV battery. Just odd that none of the 3 instances above had any sort of warning/alert either beforehand or afterwards.
I’ll provide updates here once my car is able to be looked at. Any thoughts/ideas in the meantime are appreciated.
