2022 R1S Not Charging at Home or Public Chargers

Vehicle: 2022 Rivian R1S Dual-Motor

Hello Rivian owners, I'm having a serious problem with my 2022 R1S Dual-Motor. For the past two days, it refuses to charge. I've tried my Rivian Wall Charger at home, a public Level 2 charger, and even a DC Fast Charger, and nothing works. The charging indicator light on the port just stays white, or sometimes flashes red briefly before going back to white, and the in-car display shows 'Charging Fault' or 'Charging Interrupted'.

I've tried unplugging and replugging, restarting the vehicle, and even checking my home breaker, but no luck. My wall charger worked perfectly fine last week. The vehicle has about 25,000 miles on it. Has anyone experienced a complete failure to charge like this across multiple charging types?

I'm currently stuck with a low battery, and this is quite frustrating. Is there a common component that could fail and cause all charging to stop? Or is this likely a major battery management system issue? Any thoughts or similar experiences would be helpful before I call for a tow.

ClearTheCode admin answer:

Experiencing a complete failure to charge across multiple charging types on your 2022 Rivian R1S is a significant issue that points to a problem within the vehicle's internal charging system, rather than an external charger fault. Here's a breakdown of potential causes and actions:

  1. Initial Checks (Already Performed): You've correctly tried different chargers and restarts. This helps rule out external charger or simple communication issues.
  2. Common Causes for 'Charging Fault':
    • Onboard Charger (OBC) Failure: The OBC is responsible for converting AC power (from Level 1/2 chargers) into DC power to charge the battery. A fault here would prevent AC charging. While DC Fast Charging bypasses the OBC for the main power conversion, some control signals still pass through related systems.
    • Battery Management System (BMS) Fault: The BMS monitors and controls the entire battery pack, including charging. If the BMS detects an unsafe condition (e.g., voltage imbalance, temperature anomaly), it will prevent charging to protect the battery. This is a common cause for 'Charging Fault' across all charger types.
    • Charging Port Assembly/Sensors: While less likely to affect all charging types simultaneously, a faulty sensor within the charging port (e.g., proximity sensor, temperature sensor) or an issue with the communication pins could prevent the vehicle from initiating a charge session.
    • High-Voltage Contactor Issue: Contactors are switches that connect the battery to the charging system. If one fails to close, charging cannot occur.
    • Software Glitch: A severe software bug could potentially disrupt charging protocols, though this usually manifests differently than a complete, persistent failure.
  3. Diagnostics: The vehicle's internal diagnostic system will have logged specific DTCs related to the charging fault. These codes are crucial for pinpointing the exact component or system that has failed. Rivian service technicians use specialized tools to access these codes.
  4. When to See a Shop: A persistent 'Charging Fault' that prevents all forms of charging is a critical issue. It's unsafe to attempt to diagnose or repair high-voltage charging components yourself. Contact Rivian Service immediately. They will likely arrange for a tow to a service center. Provide them with details of the warnings and the steps you've already taken.
