My vehicle constantly receives an error message while driving stating, "SERVICE HIGH VOLTAGE SYSTEM" and "REDUCED ACCELERATION DRIVE WITH CARE." Error symbols appear on the dashboard that show an orange turtle, a red battery with a big exclamation point through it and and a red car outline with a big exclamation point going through the middle of it. When this happens, the vehicle acceleration is significantly reduced and the regenerative braking or "one-pedal" feature automatically becomes disabled. If you're relying on that system to brake, it will not do so when you need it to and you have to manually press the brake to slow and stop the vehicle. This error clears after a few days of driving but never fails to return. The dealer said they found nothing wrong when I brought it in (when the error wasn't being displayed, of course) but it went back today with the error displayed so they could witness it for themselves. Separately, the vehicle makes an incredibly loud knocking noise when accelerating with the wheel turned. It appears this is coming from the CV joints.
NHTSA complaint #11726755 — an unverified report by a vehicle owner.
I have had multiple occurrences where as I'm accelerating into a turn at normal /slow speeds the traction control activates and my vehicle almost comes to a stop almost causing an accident with the vehicles behind me. This was on dry pavement and not heavy acceleration so the traction system should not have activated.
NHTSA complaint #11722435 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11721697 — an unverified report by a vehicle owner.
Clicking noises when turning. Dealership no longer fixing (fixed passenger side, driver side still unrepaired). Front end collision breaking happening at random, causing unsafe breaking in the middle of the road. Also frequently happening when releasing break at stop light, narrowly avoiding multiple rear end collisions due to breaks being slammed on by vehicle collision system. Now with high voltage battery failure message, blowing cold air out of hvac system and performing at reduced acceleration.
NHTSA complaint #11718298 — an unverified report by a vehicle owner.
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
NHTSA complaint #11714966 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11714338 — an unverified report by a vehicle owner.
During a normal commute on the highway, the vehicle suddenly lost all engine power and stalled in the middle of high speed traffic. The vehicle could not exceed 8 mph while attempting to pull to the side of the road for safety. There were no warning lights (other than a low tire pressures - normal for cold days) and no error messages. The car was unable to get started for about 10 minutes. Eventually, the engine started and the vehicle was able to make it back to our residence. The battery was near 55% at the time of the incident (out of a maximum of 80% recommended charge) In terms of safety, this was a near fatal incident, as suddenly losing power and stalling in the middle of the highway during high speed traffic and snowy conditions could have been devastating.

First of all, my Honda app took me a month to get into and sign in due to app issues which are very annoying and when I drive my car and turn the wheel, it makes axel sounds my screen shut off on me. One time I got a high voltage system warning the battery drains out quick. The door hits the other door every time you open driver side
NHTSA complaint #11712785 — an unverified report by a vehicle owner.
Loud clicking and thumping noises from area of wheel drive axles. This predominantly occurs when the front wheels are turned off center. Clicking in axles and loud thumping in the chassis are enhanced with acceleration.

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.
NHTSA complaint #11709753 — an unverified report by a vehicle owner.
On December 1, 2025, the 2025 Honda Prologue was pulling into a parking spot between two parked vehicles at low speed. While in forward gear, the Prologue experienced an unexpected acceleration event and collided with three parked vehicles, two of whom were hit with sufficient force to impact adjacent parked vehicles. The driver is unaware of having pressed down on the accelerator and is additionally concerned about why none of the vehicle safety features such as the equipped Collision Mitigation Braking System (CMBS) activated to prevent these collisions. The vehicle was brought to a local Honda dealership, yet they were unable to draw any conclusions regarding why the unexpected acceleration event occurred. The vehicle owner requested a DTC scan report and EDR (event data recording) data from the vehicle, and received the DTC report but not EDR data. The Honda dealership advised calling the American Honda customer service line with the case number to obtain EDR data. The customer service line was not able to assist because they were not able to identify the case manager, which points to a documentation error within Honda servicing processes.

The “check high voltage system” warning came on, we noticed the hearing stopped. This started after 12,000 miles. The dealership said they fixed it and gave it back the warning reappeared a few days later, same events we lost heat and then the warning came back on. We have it back at the dealership they still don’t know what’s wrong.

Only had the car 6,000 miles in 3 months. Received a service high voltage system warning causing the car to not be no longer produce heat, including for the battery. This rendered it unable to charge. A dead battery is a dead car. It’s currently been in the shop waiting on back ordered part for 25 days.
NHTSA complaint #11705437 — an unverified report by a vehicle owner.
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. Insane

Yesterday 11/30/25 we were going on the freeway about 60 mph, when suddenly I got the warning that my battery and acceleration were impacted due to a battery issue. States to service battery soon. It stayed that way as we were headed to have some blood work. That warning continued until the evening when it disappeared so thought it was a glitch. I still setup an appointment to have it checked at the dealership on Thursday 12/4/25 at 8:15am. On 12/1/25 at around 7:35am I was about to break at a light when I feel this jolt from my car and the same warning lights stayed on. I was really concerned so when I got off and went to work I immediately called the service department to move my appointment up to Tuesday 12/2/25 at 7am first thing. I dropped off the car at night for them to work on it. This seemed to impact also the Heater as it was cold air coming from my vents. I have seen this issue in Facebook and Reddit but felt I may not experience it as I had 8000+ miles on it with various long road trips. But now I am worried about the reliability and safety of this vehicle. Hope they can fix it and soon.

The contact owns a 2024 Honda Prologue. The contact stated that while attempting to start the vehicle, the vehicle briefly failed to start as expected, but internal electronics showed signs of power. After which, the message "Battery Low" and "Service High Voltage System" were displayed, even though the battery indicator showed that the battery was charged to 90%. The vehicle returned to normal functionality, but the failure became a regular occurrence. The Hybrid Battery warning light was illuminated. The vehicle was towed to the dealer, who informed the contact that the vehicle was functioning as intended during the time it was in the service center for diagnosis, and no faults were found. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 10,900.

Service high voltage error keeps coming on. Have had it serviced by the dealer multiple times. Seems to be a common error with all Honda prologues but Honda has yet to address the problem.
