The vehicle experienced multiple serious issues affecting safety and reliability. The 12V battery failed, leaving the vehicle unable to start. In addition, there is a persistent abnormal ratcheting or grinding noise when turning, indicating a possible drivetrain or steering-related defect. An interior component near the rearview mirror also detached while driving, creating a distraction and safety concern. The vehicle was taken to the dealership for repair on February 21, 2026 and has remained out of service for over 30 days with no confirmed repair completion date. There have been communication issues with the dealership, including lack of documentation and inconsistent updates regarding the status of the vehicle. Due to the extended downtime, unresolved defects, and safety concerns, the vehicle is unreliable and unusable for its intended purpose.

Broken/Clicking CV joints. This could lead to all loss of power transfer to the wheels, causing a sudden and unexpected stop to the vehicle while driving. Honda is aware of this defect, but has no permanent fix. This is confirmed by multiple Honda Service Centers. High Voltage Warning. Loss of heat, car will not charge, car shuts down/becomes undrivable, or enters "limp mode." This is an extreme safety issue. The car loses the ability to properly cool the main battery. This could result in thermal runaway (a rapid, uncontrollable, and self-sustaining increase in battery cell temperature), resulting in a fire that is difficult to extinguish, burns extremely hot, may reignite hours or days after the initial incident, and/or result in explosion. This is confirmed by multiple Honda Dealerships. The warning has occurred multiple times, even after multiple repair attempts.

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.

High voltage warning light, service vehicle soon light, reduced speed limit, would not charge past 25%, forward looking camera issues warning light would show up randomly Called the local Honda dealer(01/26/26), talked with service manager, He told me to bring the vehicle in immediately. The Honda dealer refused to fix it under warranty since it was in an accident.(Right fender and driver door needed repaired.) The dealer wanted $300 dollars to perform a diagnostic test on vehicle. Dealer found that the HVAC system had failed which also includes the 12 volt charging system to also fail. Dealer wanted an additional $800 for further diagnostic testing. Informed me that the full warranty was void do to it being in a previous accident and I will be responsible for all repairs for this vehicle. Contacted Honda headquarters and filed a complaint thru them. The car was towed to another dealer where they are working on it currently. No new updates as of 02/02/26

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.

- Peabody, MA, USA

When driving, frequent knocking sounds can be heard coming from the engine when at a stop to turn, and accelerate. The electrical system was faulty with the engine electrical system indicating problems- the heater shut off, so we had no heat during a 90-minute road trip. Tire pressure monitor indicates low tirepressure and seems unresponsive. I brought it in for service. The electrical system was fixed, but the tire pressure remained low, was noit addressed and return to me with all tires at 32psi. Maintenance person commented, " Sir, all I do is return the vehicle to you"... Please advise. Thank you 4900

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.

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.

Three major problems stand out: faulty CV joints/axles that produce loud clicking or knocking noises when turning, false activations of the automatic emergency braking (AEB) system, which I had to turn off, and high-voltage system failures that can disable charging or limit performance. Other concerning issues include steering malfunctions, infotainment system blackouts, USB-C not connecting, battery not charging to 300mi range, forward collision sensor false activation, and braking anomalies.

- Fort Worth, TX, USA

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.

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.

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

- York, PA, USA

Went to start vehicle and warning light was present on main screen signaling HIGH VOLTAGE SYSTEM ERROR. I called the local Honda service team who had me check to see if the car would charge. The tech said n the phone was concerned that the battery could be -??bricked-?? meaning in non-operational status. The car did indeed charge and drove it immediately down to service adviser per his recommendation. Honda service team determined that an AC line was dripping on electrical components. The Honda service team was able to fix stated issue.

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.

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.

I was driving my car and suddenly I received high voltage battery warning and I had to stop my car in between of freeway.

I have had multiple issues with this vehicle and it has been in the shop more than 80 days between April and Oct 2025. First, the entire battery system went out in the all electric vehicle. Honda said that since it was a collaboration car with GM, that it would take a long time to fix because their technicians weren-??t very familiar. It took almost 8 weeks in the shop before we got it back. Not long after, the entire dash (electronics) went out and the shop had it again for over a week. they never found or could replicate the issue. The vehicle went back in after having multiple incidents of emergency braking when there was no emergency, or even vehicles in my vicinity. The final time this happened, I was traveling nearly 25 miles per hour and the car decided to slam on the brakes, making me feel like I hit a brick wall. My head slammed the steering wheel and my daughter was terrified. I drove it straight to the dealership and they said -??what-??s wrong with the car this time-??-??they had it for weeks, couldn-??t replicate the issue and tell me it-??s fine and to take it home. They suggest TURNING OFF THE SAFETY STSTEM AS A FIX, which seems criminal. The safety features should work properly. I shouldn-??t be instructed to turn them off. I am very frustrated and have been working with Honda on a buy back out of good faith, but it-??s been weeks and we have no answer. I am forced to drive a gas vehicle, costing me gas money now, when I bought an electric vehicle to avoid this cost. All around, it has cost me more money than it-??s been worth and I-??ve made multiple car payments as it-??s sat at a dealership unusable. Again, it has spent more than 80 days in 6 months at the dealer with no resolution. My sound system blew out last time they had it checking out the braking issue so I waited another week to have that replaced, meanwhile the fix to the braking system was that I was told to turn the safety feature off.

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.

My 2024 honda prologue was brought in to service a battery failure light and get a clicking noise in the front axel looked at when turning. The light was a red on the dash shaped like a car with an exclamation point. Dealer claimed that the multiple codes were nothing and that the car needs a new audio system. Not sure how audio systems = battery failure but i digress. I was told my car is safe to drive so I picked it up, they have still not made any repairs as the audio system is on back order. The morning after i picked it up, the heater started blowing ice cold air, in 10 degree weather. Immediately returned to the dealer where they are saying they don-??t know what-??s wrong with it and they think it is still safe to drive
