2024 Lyriq Charging Port Not Locking / Slow Charging Issues

Vehicle: 2024 Cadillac Lyriq Luxury

I'm having some frustrating issues with the charging port on my brand new 2024 Cadillac Lyriq Luxury. Sometimes when I plug in my Level 2 charger at home, the charging port door doesn't seem to lock the cable in place, or it takes multiple attempts to get it to engage. Other times, it starts charging but at a much slower rate than usual, or it just stops charging altogether after a few minutes.

I've tried different chargers and outlets, and the problem seems to be with the car itself. Is this a known issue with the Lyriq's charging system? It's a bit concerning for a new EV. Any ideas on what might be going on?

ClearTheCode admin answer:

Issues with the charging port not locking, slow charging, or intermittent charging on your 2024 Cadillac Lyriq are critical concerns for an EV owner. These problems typically stem from the charging port assembly, its locking mechanism, or the vehicle's charging control module.

Common Causes:

  1. Charging Port Latch Actuator: The motor or mechanism responsible for locking the charging cable can fail, preventing a secure connection.
  2. Charging Control Module (CCM) Fault: The CCM manages the charging process and communication with the EVSE (Electric Vehicle Supply Equipment). A fault here can lead to incorrect charging rates or premature termination.
  3. Wiring/Connector Issues: Damaged or loose wiring within the charging port assembly or leading to the CCM can disrupt power flow or communication signals.
  4. Communication Errors: The vehicle and charger communicate extensively. Any glitch in this communication (e.g., due to a faulty pin in the port) can cause charging to slow or stop.
  5. Software Glitch: As a newer EV, software bugs can sometimes affect charging protocols.
  6. Debris in Port: While less likely for a new car, debris or moisture in the charging port could interfere with connections.

Relevant OBD-II Codes (may require specialized EV diagnostic tools):

  • P0D2F: Charge Port Latch Circuit
  • P0D2A: Charge Port Communication Error
  • P0D2B: Charge Port Proximity Sensor Circuit
  • P0D2C: Charge Port Control Pilot Circuit

Troubleshooting Steps:

  1. Inspect Port: Visually inspect the charging port for any visible debris, bent pins, or signs of damage.
  2. Try Different Charger/Location: You've already done this, which helps confirm the issue is likely with the vehicle.
  3. Vehicle Restart: Sometimes a full power cycle of the vehicle (turning it off, waiting a few minutes, then restarting) can clear temporary software glitches.

When to See a Shop: Given that this is a brand new 2024 Lyriq and the issue directly impacts its primary function (charging), it is imperative to take your vehicle to a certified Cadillac EV service center immediately. Do not attempt to force the charging cable or perform extensive DIY diagnostics, as this could void warranties or cause further damage. The dealership has specialized diagnostic equipment and trained technicians who can accurately diagnose the charging system, check for specific EV-related fault codes, and perform any necessary repairs or software updates under warranty.
