With that many warning lights illuminated did they (dealership) check to see if/what DTC's it was showing if any? Did they give a reason to suspect the floor harness needed replacing? Reason for asking is it has been documented that rodents will eat wires on newer cars "Rats can't resist wiring in newer cars: Here's why". There is a thread on this forum regarding rodents getting into a Gen X Accord - Rodent problem. Warning graphic picture. Also found another article of a Honda owner having this issue - Rats! Warranty won’t cover rodents chewing wires, so Arlington Heights man sues Honda.So my 2018 Honda Accord lx drives fine but has 15 error messages on startup and recently just started displaying weird colors on the rear backup camera after sitting for a about a year and half not started. Initially it wouldnt start and needed a jumpstart Everytime and then would drive rough and give off error messages about the alternator. I took it to the dealership and they replaced the alternator and battery and now it drives fine except for the issues stated below. The dealership is now telling me I may need a new SRS unit and floor harness to get rid of the messages but they are not sure if that would even be the full resolution. I was in the process of getting the repair done but the floor harness is on backorder and would take months to ship it out. I can't get it fixed under warranty and have to pay out of pocket. Besides all of the current issues stated, after getting the alternator and battery issue fixed the car can get to point A to point B fine. I was wondering if anyone has had a similar issue and has gotten it resolved and what they recommend I get replaced. I will attach photos to help show what I'm dealing with.
These are the messages that pop up on the dash on startup.
- Electric Parking Brake System Problem (Works fine though)
- Tire Pressure Monitor System Problem
- Emissions System Problem
- Brake System Problem
- Brake Hold System Problem
- Supplemental Restraint System Problem
- Electric Power Steering System Problem (Haven't noticed issues with steering)
- Vehicle Stability Assist System Problem
- Hill Start Assist Problem
- Adaptive Cruise Control System Problem
- Lane Keeping Assist System Problem
- Collision Mitigation Breaking System Problem
- Road Departure Mitigation System Problem
- Auto High-Beam Problem (High beams manually work though)
- Systems Initiallizing... Continue Driving
From what I understand and have read when their is a loss of power (battery disconnect) once the car is driven and restarted warnings would go off that were related to that loss of power.
Not to make light of your situation however... After reading this with my car not being my daily driver (and even less driving due to pandemic) I'm glad I make a habit of driving it at least every other week if not more. I take it out on the highway and drive for 60/90 minutes to charge battery, keep components lubricated, get oil up to operating temps, etc., etc. What you are dealing with shows how much technology (electronics) are in our cars and how gremlins can appear when those systems go long periods of time w/o power.
Good luck in getting this resolved and let us know the outcome.
