In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
We had our Honda Prologue just a couple weeks and decided to drive to the mountains. On the way up, we got several error messages: "Service High Voltage System", "Service Vehicle Soon" and "Reduced Acceleration, Drive with Care". 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.
On 13 August 2024 I was driving my 2024 Honda Prologue when the DIC and infotainment screens went blank. At this time with no information displayed on any screen, the car was unsafe to operate. I drove the car straight to the local dealer, Tony Honda. The dealer was unable to diagnose the problem.
After charging my car from ~20% to 80% over the course of ~8 hours, I powered on the car, reversed out of my parking space, and began driving. Shortly after (<1 min), I noticed that both my Instrument Panel screen and my Infotainment screen had shut off and were black.
I turned my car on and the screens were on, I put it in drive and both screens went black, I pulled over and I restarted the car multiple times, nothing would come on. I had to drive one hour to work without being able to see how fast I was going, or how many miles. It was completely dark and this is a serious safety issue

Source: NHTSA complaint database, recalls and manufacturer communicationsAre electrical problems common on the 2024 Honda Prologue?
They are documented: NHTSA holds 165 owner complaints naming the electrical system on this model year (20% of everything owners filed about it), and 11 manufacturer bulletins are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the electrical system on the 2024 Honda Prologue?

Wiring, modules, batteries, charging, infotainment and driver displays — NHTSA's broadest heading. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
