Vehicle: 2023 Rivian R1T Launch Edition

Hey everyone,

I'm a new owner of a 2023 Rivian R1T Launch Edition, and I've been loving it so far. However, for the past week, I've started getting an intermittent 'Charging Fault' error message when trying to charge at home with my Rivian Wall Charger. Sometimes it charges fine, other times it just stops after a few minutes, or doesn't start at all.

I've tried unplugging and replugging, restarting the truck, and even checking the charger's circuit breaker. The issue seems inconsistent, and it's making me nervous about longer trips. I'm worried about battery health or if it's a problem with the charging port itself.

Has anyone with a 2023 R1T experienced this? What was the fix? Is this something I can troubleshoot myself or do I need to schedule service right away? Any advice would be greatly appreciated!

ClearTheCode admin answer:

It's concerning to experience intermittent charging faults with your new 2023 Rivian R1T. This issue, while frustrating, can often be narrowed down with a few diagnostic steps before needing a service appointment. Here’s a breakdown of potential causes and troubleshooting:

  1. Check Rivian App and Vehicle Display: Look for more specific error codes or detailed messages within your Rivian app or on the vehicle's large display. These can sometimes point directly to the source of the problem, such as a communication error or an issue with the power supply.
  2. Try a Different Charging Source: If possible, attempt to charge your R1T at a public Level 2 charger or a DC Fast Charger (like a Rivian Adventure Network charger). If the vehicle charges without issue there, it strongly suggests the problem lies with your home charging setup (Rivian Wall Charger, home electrical system, or the connection to it).
  3. Inspect Charging Port and Cable: Carefully examine your R1T's charging port for any debris, bent pins, or visible damage. Do the same for your Rivian Wall Charger's cable and plug. Even a small obstruction can prevent a proper connection.
  4. Perform a Vehicle Reset: A soft reset of your Rivian (often done through the infotainment system or by holding down specific steering wheel buttons) can sometimes clear temporary software glitches that might be causing communication errors with the charger.

Potential Causes:

  • Software Glitch: Rivian vehicles are highly integrated with software, and a temporary bug can sometimes cause charging communication errors.
  • Charging Equipment Fault: The Rivian Wall Charger itself, the cable, or the vehicle's internal charging port could have a defect.
  • Home Electrical System Issue: Problems with your dedicated circuit, breaker, or wiring in your home can lead to inconsistent power delivery.

When to See a Shop: If the 'Charging Fault' persists after trying these troubleshooting steps, especially if it occurs with multiple charging sources, it's time to schedule service with Rivian. They have specialized diagnostic tools to pull specific Rivian diagnostic trouble codes (DTCs) and pinpoint whether the issue is with the vehicle's onboard charging system, battery management system, or the charging port itself. Do not delay service if you suspect a serious electrical fault.
