2019 Nissan Sentra – Power Steering, A/C, Backup Camera, AEB, Slip Light & Electrical Issues After Fuse Removal

I have a 2019 Nissan Sentra with approximately 148,000 miles. About a year ago, the Automatic Emergency Braking (AEB) warning light came on and would only clear temporarily if I manually disabled the system. A few months later, the Slip Indicator light came on and stayed on continuously. More recently, the Low Tire Pressure warning light came on even though all tires are properly inflated.

A couple of weeks ago, my driver-side headlight (high and low beam) stopped working. While checking the fuses, the headlight/IPDM fuse was removed and reinserted with the battery still connected. After that, several systems stopped working.

Current symptoms:

• Power steering not working (very hard to steer)

• A/C control panel completely dead

• Backup camera not functioning

• AEB warning light on

• Slip Indicator light on

• TPMS warning light on

• High-pitched electrical noise while driving

Repairs already completed:

• New battery

• New alternator

• New serpentine belt

• New battery terminals

• New fusible link

Nissan performed a diagnostic and recommended replacing the battery terminals and fusible link, which were replaced, but the issues remain. They then suggested replacing the steering column motor for approximately $5,000, but did not address the other electrical issues.

I recently took the vehicle to a Nissan specialty shop. After the first hour of diagnostics, they still have not identified the root cause and are requesting additional diagnostic time.

Has anyone experienced a similar combination of issues on a 2019 Sentra? If so, what was the actual cause? IPDM failure, wiring damage, grounding issue, CAN communication issue, steering module, or something else?

Any insight would be greatly appreciated.
