RE: Unrepaired Recalls associated with this VIN [XXX] Feb 26,2026 Manufacturer Recall NumberXNK NHTSA Recall Number26V-112 My name is [XXX] , I lease a 2024 Honda Prologue. I received a recall and took my car to Crown Honda in St Petersburg, Fl to have it done. I’ve been there 4 times to have it done and it failed 3 of the 4 times. The 4th time, they only did a partial update and told me it was complete and are telling me if I want more it’s going to cost me. I discovered they did not perform the Recall update. The paperwork they gave me shows it has to be a USB update. I know from my experience and my background of decades in the computer technology business, that they have minimal experience in that field. I called Honda corporate and they told me it was my problem and to go to another dealer. I’m hoping you may be able to help me out and contact them to get my updates performed. My recall shows it is a serious matter. As of this date and your records confirm, the recall is still incomplete. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The onboard navigation and entertainment system, including both the primary dashboard/driver interface and the center console, went fully black for over 1 minute while driving on the highway. When the screen is blank, no input is available from the vehicle as to speeds, behavior of cruise control, warning systems such as lane control, front rear and side awareness, operator awareness of speed, other vehicle warnings. Bringing to dealer today. this is the 2nd time this has occurred. The first time was in December. Vehicle was brought to dealer for software update. Update “bricked” the car, and a new radio module needed to be ordered. This took about 6 weeks. Module installed, software was updated, and this was to have addressed the issue. While records may indicate that the update was not yet performed on the vehicle, it was fully updated and the vehicle (according to the dealer) is fully up to date and the recall for it has been addressed with the software update. However, the update did not address the issue. No other inspections have occurred to date. No other symptoms or warning lights.
For the second time in 2 weeks, my car has had a “Service High Voltage System” warning. The HVAC failed and car has blown cold air while heat is on.
This vehicle is experiencing constant malfunctions with the infotainment system. It constantly flickers, freezes, and blacks out completely during normal driving conditions. This is prohibiting use of features controlled by the unit including charge settings and rear camera use. This has been a constant issue with this car and has been checked by Honda Henderson multiple times and all attempts have failed to resolve.
At random times, usually when the battery is below 40% I will get warnings that say "reduced acceleration drive with car". I've own the car for a year (brand new) and this has happened at least half a dozen times or more.
Vehicle is unable to charge. Dealer inspection confirmed damage to the charging coupler/receptacle. Charging port shows burn marks and electrical damage. Dealer recommended replacement of the drive motor battery charger receptacle. Vehicle has no diagnostic trouble codes. No accidents, no misuse, no aftermarket equipment. Failure occurred during normal home charging. Honda dealer and Honda USA denied warranty coverage. This defect prevents vehicle operation and presents potential electrical and fire safety risk.
I was driving and both screens went completely black. Vehicle was charged to over 80%. I could not see speed or any other vehicle information on either screen. After about 5 seconds the screen above the steering wheel started to load back up and then the other screen followed.
The digital instrument cluster (dashboard screen) and the infotainment screen went black while I was driving. This meant I was unable to see my MHP or any critical information on my car. I was listening to music and first it stopped, then a moment later both screens went black. This lasted for 30 seconds until one came on followed by the other.
High voltage system error has flagged and been fixed multiple times starting in early January of 2026. Car randomly warns and breaks in the middle of the road because it sensed something that wasn’t there. Luckily no wrecks have occurred. Both CV joints have a loud clicking noise that the Honda dealerships knows about but has no fix for. I currently have an appointment for the dealership to look at my brake and high voltage system again.
Leased this car 1 year ago and it is currently in the repair shop for the 2nd time in a year for the same battery problem: battery won't charge and an error notice on the dashboard that says " Service high voltage system. Reduce acceleration. Drive with care". The first time the shop said that it was a software issue and fixed it. Now the shop is saying that the car needs a new battery. The error notice came up while I was on a road trip and I felt unsafe knowing that the battery could fail or combust while driving. Also, I did not feel safe having the reduced acceleration in effect while I was on the freeway where acceleration can be essential to match traffic and evade accidents.
Main screen that operates the vehicle shuts off periodically and will not return on. Upon restart multiple times the screen will partially open and appear on but touch screen features does not work. This prevents the driver from accessing the radio, turn lights on, turn fog lights on off, change charge settings, and accessing all vehicle safety and non-safety related items. Car does still drives despite not having a functional and operational screen. Dealer has been notified and service appointment set for 12/29.
While driving at freeway speeds, a red check engine warning appeared along with a “Service High Voltage System” message. Immediately afterward, the vehicle’s heater stopped working, causing the windshield to fog up. I had to pull over safely and manually clear the windshield before driving the vehicle to the dealership.
Service High Voltage System alarm + Service Vehicle Soon alarm warning. This with no heat while driving at 10,836 miles. Took in to dealer for service and reportedly a known problem with the freon system and end cap. My thought is this should be a recall fix by Honda/GM because there are many many complaints of it amongst 2024 Prologue Owners.
The contact owns a 2024 Honda Prologue. The contact stated that while driving approximately 65 MPH, there was an abnormal clicking sound coming from the instrument cluster, and the instrument cluster went black. The contact then drove the vehicle to a local dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 8,000.
Car shows a turtle image on dash and will not go faster than 30mph nor will it fully charge without dealer intervention. This happens when it's cold. There's also a clicking sound when turning as well that's a whole other issue.
Two weeks ago, an alert appeared stating that the charge port door was open. The door was closed and no amount of opening and closing the door would stop the alert from repeatedly appearing. After about 2 hours, a new alert would appear either before or after the the alert for the charge door. The new alert told me to service the high voltage charging system. The issue has been confirmed with the dealership, however, they refuse to fix the problem under warranty because they state that the issue is the internal position sensor for the charging port door and that is not one of the more common causes of this, apparently, very common issue with this vehicle. Considering the volume of complaints about this issue, I find that hard to believe and refused to pay for a known issue with the Prologue. Most other owners with the issue have found that despite being told by the dealership that the sensor was the issue, it was actually the AC or battery that was the problem. This is a safety issue because something is wrong with the charging system of an EV, which can eventually cause a major defect in the vehicle and Honda won't fix it under warranty.
Dashboard warning "High Voltage System Service Soon" came on while driving. Phoned dealer. Made service appointment. Started car and warning notice had disappeared. Drove car to dealer, who checked and told me there were "multiple error codes relating to various electrical issues" and "the case is going to be elevated to Honda's tech/engineering team." The car will be at the dealership for 7 days at this point.
I was driving my car and suddenly I received high voltage battery warning and I had to stop my car in between of freeway.
This car presenta High Voltage Issue, I bring the car to the services 3 times. AND i see online a lot of people with the same problem
