Vehicle: 2023 Rivian R1T Adventure

Hey everyone,

I've been having some frustrating issues with my 2023 Rivian R1T Adventure lately, specifically with charging at home. For the past week or so, it either charges incredibly slowly, taking well over 12 hours for a partial charge, or it just stops charging completely once it hits around 80%. I'm using a dedicated Level 2 charger that was professionally installed, and it's been working perfectly for months.

I've checked the Rivian app and the vehicle's settings, and there's no charging limit set to 80%, nor is there a scheduled charging time interfering. I've also tried unplugging and replugging the charger multiple times, but the problem persists. It's really impacting my daily routine, as I rely on overnight charging.

Has anyone else experienced similar charging problems with their R1T? Could this be a software glitch, an issue with the vehicle's charging port, or something more serious with the battery management system? Any advice or troubleshooting steps would be greatly appreciated before I have to schedule a service appointment.

ClearTheCode admin answer:

It sounds like you're dealing with a common, albeit frustrating, issue that can affect EV charging. Slow charging or charging stopping prematurely can stem from several sources. Here’s a breakdown of potential causes and troubleshooting steps:

Potential Causes:

  1. Charging Settings: While you've checked, sometimes a hidden or forgotten setting (like a specific departure time charge or a lower amperage limit) can interfere.
  2. EVSE (Charger) Fault: The charging station itself, or its internal components, could be malfunctioning, leading to reduced power delivery or communication errors with the vehicle.
  3. Home Electrical System: Issues with your home's wiring, a tripped breaker, or voltage fluctuations can impact charging efficiency.
  4. Vehicle Software Glitch: A temporary bug in the Rivian's battery management system (BMS) or charging control software can cause erratic behavior.
  5. Battery Management System (BMS) or Charging Port Hardware: Less common, but a fault in the vehicle's internal charging components or the charging port itself could be the culprit.
  6. Thermal Management: In extreme temperatures, the vehicle might limit charging speed to protect the battery.

Troubleshooting Steps:

  1. Double-Check All Settings:
    • In the Rivian app and on the vehicle's touchscreen, thoroughly review all charging schedules, charge limits, and amperage settings. Ensure no 'soft' limits are active.
  2. Inspect EVSE and Cable:
    • Examine your Level 2 charger unit and the charging cable for any visible damage, frayed wires, or bent pins in the connector.
  3. Try a Different Charger:
    • Attempt to charge your R1T at a public Level 2 or DC fast charger. If it charges normally there, it points to an issue with your home EVSE or electrical setup.
  4. Perform a Vehicle Soft Reset:
    • Sometimes, a simple reboot can clear software glitches. Consult your Rivian manual for the correct procedure to perform a soft reset (often involves holding down steering wheel buttons).
  5. Check for Diagnostic Codes:
    • Look for any alerts or diagnostic messages on your Rivian's display or within the Rivian app. While specific OBD-II codes for Rivian's high-voltage system aren't always publicly accessible via generic scanners, the vehicle's internal diagnostics might show a code like P0D26 (Charging System Performance) or P0D27 (Charging System Voltage Low) if there's a significant issue. These internal alerts are crucial.

When to See a Shop:

If the problem persists after trying these steps, especially if you've ruled out your home charger by successfully charging elsewhere, it's time to contact Rivian Service. This indicates a potential issue with the vehicle's internal charging components, battery management system, or a more persistent software bug that requires professional diagnosis and potentially a firmware update or hardware repair. Provide them with any diagnostic messages or codes you've observed.
