The dash and infotainment shut down and went completely blank screen while driving. No speedometer. No information on how fast I was going.

- Oceanside, CA, USA

I turned on the car and backed out of my driveway and my infotainment and gauge cluster screens both went black. I pulled over to the side of the road because I could not see what my speed was and I couldn-??t see what gear I was in. I restarted the car multiple times and it finally turned back on. I also realized later that I wouldn-??t be able to turn on my headlights if it was dark outside. This is very unsafe and should be fixed. I do not believe I am the only one with this issue as I have seen many many others.

when you setup your EV to charge over night to 80 percent or what ever percentage it will charge more then what you programmed it to do....it will be more. Which can be very dangerous. It continues to do this since day one.

My 2024 Honda Prologue had less than 900 miles on it when "High Voltage Warning" appeared on my dash, and warned me to take the vehicle to a service center immediately - I did, and now my Prologue has been in service for 20 days straight. (As of 1-17-25)

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. This becomes a huge safety issue as any vehicle system that is available from a button press can be turned on or off randomly. This problem is repeatable and happens every time the headlights are on.

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. We had to get towed back to the dealer. It was in for a couple days before being returned. They said they had: 1) "Done a hard battery reset"; and 2) serviced the A/C system". The car seems to be working OK but we are wary of taking it on longer drives. This seems to be a common issue on Hondaprologue forums.

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 contacting Honda Tech support, they decided the audio control unit was defective. After 65 days the dealer was able to replace the unit and it seems to work properly. Honda informed the dealer the car was safe to operate without any display screens or information. Actually the car was unsafe to drive with no speedometer indication or any other control functioning.

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 continued driving for another 2-3 minutes before pulling into a parking lot. In the lot I powered the car on and off many times, and also powered the car on in Service Mode. During each of these power cycles both screens remained black. About an hour later I returned to the car and again the screens did not turn on. I drove the car about half a mile, stopped and turned it off again for around 30 minutes. After coming back to the car this time, the screens worked as normal. My safety was put at risk because without my instrument panel, I lose almost all feedback and situational awareness of the state of the car. Also, while backing out of a parking space while the screens were not working, I did not have access to my back-up camera. I have not yet taken the car to a dealer or mechanic. I am writing this report directly after the screens resumed operating. I did not see any warning lamps or messages prior to the failure. But when I entered the car initially, I did notice that the infotainment screen was turned on and at a screen that otherwise is not seen until I turn on the car.

Both screens suddenly turned black while I was driving. I had no way to restart the screen, even after shutting off the car and turning back off. The two black screen remain on, but no way to see charging status, speed, control lights, etc.

- New York, NY, USA

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.

About 30 miles after starting a 1,500-mile road trip, the infotainment screen and driver instrument panel both went completely blank. After about 60 seconds, the system apparently rebooted, restoring both screens to normal operation. However, during that minute I was driving at approximately 75 mph on Interstate 90, and I had no access to certain vehicle controls and no way to verify my speed or see messages about cruise control. The error generated no warning lights or error codes, so I have not reported the issue to the manufacturer or dealership. The issue occurred with the odometer at about 180 miles. The odometer is now at about 1650 miles. I have not experienced the issue again.

On Dec. 19 the infotainment system and the instrument panels both went blank. I was driving away from my home. I touched a button on the steering wheel that controls the content of the screen that is the main instrument panel. The heads up display failed as well. The car kept running, but I could see any information such as my speed, my battery level or any of the other usual information. I could not reboot the system by myself when I called the dealership, but they said that after I handed it over to them, that it was rebooting. I took it back home and it seems to be working normally, but nothing Planet Honda did will guarantee that this will not reoccur. Planet Honda said they have heard of this happening to others, but that it's rare. If you google this problem, you can see other Prologue owners have had this happen.. This is very upsetting and potentially dangerous to not know your speed or to be able to control the lights of the car and other items. \

While driving, both screens went completely black. Without the screens I was not able to monitor speed, no access to headlights and no access to adjust one pedal driving mode. All audio stopped as well. At first I didn-??t know if I lost power to the entire vehicle, which distracted me from driving. Once I got my bearings, quickly accessed that the vehicle did not lose power, I pulled over. No warning lights or messages prior to this incident. No warning at all. It took about 10 minutes before both screens came back on. Being unable to monitor vehicle status and unable to see speed and no access to multiple options without the screen, put my safety at risk and other people around me at risk. I have not taken it in for any inspection at this time. This just happened yesterday.

On [XXX], around 8 PM, I was driving north towards DeLand, Florida on the highway at approximately 70+ miles per hour when my 2024 Honda Prologue started to slow down on its own. The air conditioning system shut down, and a warning displayed on the dash: -??Service High Voltage System.-?? I immediately drove home and contacted CarSafely, fearing that the car might become stranded and was not safe to drive. The following morning (Tuesday, [XXX]), around 8 AM, I emailed and called the Coggin DeLand Honda service department, informing them of the issue and sharing photos and a video of the incident. The error/warning disappeared after turning the vehicle on and off several times. Coggin advised me to bring the car in the next time the warning appeared on my dashboard. On Thursday, [XXX], around 12 PM, I was driving on [XXX] towards Daytona Beach at around 70 mph when the vehicle suddenly slowed down again. The air conditioning system shut down, and the service warning -??Service High Voltage System-?? appeared on my dashboard once more. I immediately got off the highway and stopped at a safe location to turn off the vehicle and document the error and warning on my dashboard. I emailed Coggin DeLand Honda again to inform them of the issue. On Friday, July 5, 2024, I took the car to the Coggin DeLand Honda service department, where they connected the vehicle to their computer for a diagnosis. The service department detected the error and reset/cleared the error code. However, the service tech informed me that they could not fix the issue due to insufficient information, as the vehicle was built by GM (General Motors Corporation). They advised me to return directly to the dealer without an appointment if the error reappeared. On Monday, [XXX], around 8 AM, while driving at approximately 25 miles per hour on a local road near my home, the -??Service High Voltage System-?? error reappeared.
