2023 R1T: 'Service Vehicle Soon' with Reduced Power and Charging Issues

Hey everyone,

I'm experiencing a concerning issue with my 2023 Rivian R1T Launch Edition. While driving yesterday, I suddenly got a 'Service Vehicle Soon' message on the dash, accompanied by a noticeable reduction in power. It felt like the truck went into a limp mode.

After pulling over and restarting, the message persisted, and the power was still limited. I also tried to charge it at home, but it's only accepting a very slow charge, much less than usual, and sometimes stops altogether. I haven't seen any specific OBD-II codes pop up on my basic scanner, but I'm wondering if there are Rivian-specific codes that might be triggered.

Has anyone else with a 2023 R1T or R1S encountered this combination of 'Service Vehicle Soon,' reduced power, and charging problems? What was the cause, and what was the fix? Any advice on what I should check before calling service would be greatly appreciated.

Summary: For 2023 R1T: 'Service Vehicle Soon' with Reduced Power and Charging Issues, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
