The car alarm goes off on its own,and the dashboard lights flash even when the car is turned off ,this continues until the battery dies and the car won’t start. I’ve taken it to the mechanic several times and no codes come up; I’ve replaced the battery with a new one twice.

To Whom It May Concern: I am requesting immediate escalation of a serious safety concern involving my 2021 Honda Pilot Touring, which I purchased as a Honda Certified Pre-Owned vehicle directly from Tempe Honda. I also purchased additional warranty coverage at the time of sale. I have owned this vehicle for less than two years, and it has already required service for an issue involving the automatic idle-stop system. That issue remains unresolved. More recently, the vehicle has begun unexpectedly shifting into neutral without any action on my part. This has occurred on multiple occasions, including when transitioning from reverse into drive and, most alarmingly, while attempting to accelerate from a complete stop at a traffic light. During these incidents, the neutral indicator actually illuminates on the dashboard. This is not simply an inconvenience or a minor performance concern. It is a potentially dangerous malfunction that places me, my passengers, and other motorists at risk. I am particularly concerned because I am a single mother who relies on this vehicle for daily transportation, including transporting my child.

The Information screen goes blank. Then at that point the backup camera will not show on screen when backing up. Creating a blind spot and hazard

Refer to [XXX]. My honda pilot started having electrical issues where the car alarm would go off randomly, radio would play at volumes randomly, dashboard lights would flicker on and off, interior lights would turn on, headlights would turn on. This resulted in multiple drained batteries and left the car inoperable until it could be jump started. This is a safety issue because if we drove somewhere without cell reception, could be stranded with a dead battery. Not to mention, it disturbed our neighbors when this occurred in the middle of the night. This is a known issue with various Honda vehicles from this timeframe. It is know as a problem with the "Remote Access Control Module," aka the "Keyless Access Control Unit," located behind the glovebox. Even though it is a known issue, Honda was unwilling to repair it at their own cost. We paid $903.22 to get it fixed.

This complaint is being filed regarding a FAILED REMEDY for the federal safety agency Safety Recall 23V‑431 (Honda Campaign ZEM) on my 2021 Honda Pilot Touring. Although the vehicle history shows that the recall repair for the MOST fiber-optic wire harness was previously performed, the authorized remedy has completely failed to fix the safety defect. The central infotainment dashboard screen regularly displays a "Network Connection Lost" error message before freezing or shutting down entirely. This failure causes an immediate, total, and unpredictable loss of the backup camera display while the vehicle is in operation. Because the backup camera is a federally mandated safety feature, its random failure creates an active safety risk for myself, my passengers, and pedestrians during reversing maneuvers. Honda customer service has refused to provide further diagnostic or repair assistance because the recall is already marked as "completed" in their database. However, the safety hazard remains active and unresolved. I request that the federal safety agency investigate this failed remedy and compel Honda to provide an effective, lasting repair for this defective system.

The electrical for the infotainment system cuts out and the rear camera is no longer on the screen, it will cause loud popping while driving as the MOST Net system is failing. There is also poor gas mileage and reads the gas tank contents incorrectly while displaying incorrect MPG typical with the fuel pump recall for this generation of Honda Pilot, but both of these recalls removed my specific year shortly after they were announced.
