Honda Prologue electrical problems, 2024–2026
198 of the 1,002 complaints owners filed with NHTSA about the Honda Prologue 2024–2026 name the electrical system (NHTSA’s “Electrical System” heading — wiring, modules, batteries, charging, infotainment and driver displays — NHTSA's broadest heading). The loudest years: 2024 (165), 2025 (32), 2026 (1). Filed under the same heading across these years: 7 manufacturer bulletins. Every figure is a linked federal record; none is a failure rate, none a repair cost, and none a verdict on one car.
Honda Prologue electrical problems by model year
Source: NHTSA complaints, recalls, investigations and manufacturer communicationsOne row per model year on file, newest first. A year marked in depth has its own page: the complaints, the owners’ words and every document under this heading for that year.
| Model year | Complaints naming the electrical system | Share of the year’s | Typically at | On file under the heading | |
|---|---|---|---|---|---|
| 2026 | 1 | 9% | — | 1 TSB | the year → |
| 2025 | 32 | 21% | — | 6 TSBs | the year → |
| 2024 in depth | 165 | 20% | — | 11 TSBs | the record → |
Two things the counts carry that are not the car: how many of each year were sold, and how long each has been on the road — an older year out-counts a newer one before anything is wrong with it. The share column is the honest comparison across years: what part of that year’s complaints named the electrical system. Nothing here is a rate.
When the electrical complaints were filed, and at what mileage

In owners’ own words

We had our Honda Prologue just a couple weeks and decided to drive to the mountains.

The car was still driveable, but we could not charge it at were stuck in the mountains.
Anytime the headlights are turned on, the center console Infotainment system starts scrolling through random menus and initiating button presses on any option available in the menu it is on. It also becomes completely unresponsive to human button presses while this happens.
The contact owns a 2025 Honda Prologue. The contact stated that while driving at various speeds, the battery suddenly experienced a loss of power. An unknown message was displayed. The vehicle was taken to a local dealer, where it was diagnosed; however, the cause of the failure was not identified. The vehicle was not repaired.
I received another service high voltage system message literally weeks after I brought my vehicle in and had the issue fixed. I reported this issue last on 11/24/2025 it is now 12/19/2025 and it happened again. The heat in my vehicle seemed to stop working and was blowing cold air. This is just poor design and disgraceful
