FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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.

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

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.

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.

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.

FUEL/PROPULSION SYSTEM
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

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
Knocking sound in the front when turning Honda states normal axel problem. For Fuel/battery . Been in a back and forth with Honda service/Honda motors because I’m getting less then advertised on my range performance. Example I drove a 60 mile drive and car drained 109z that’s 49 miles unaccounted for. I am now being told by Honda Motors mediation that the battery loses 30/40 percent efficiency in cold weather. That’s horrible. It’s not advertised and it’s unacceptable. It’s unsafe that customers can’t depend on the vehicle when an emergency happens.

Automatic braking is very sensitive, especially in the rain, and even more so when backing up in the rain. The unexpected braking happened to me at a rotary for no apparent reason, and numerous times in reverse. Service Vehicle Soon Light/(Propulsion System Failure) came on randomly at around 4000 miles. Within a day or so it turned off. Nothing with the car seemed to be effected. Then around 4500 symbol turned on again and has been on for a day or so. No notable issues.

Queens Village, NY
FUEL/PROPULSION SYSTEM
On April 19, 2025, the "Engine/Battery Fault" warning light illuminated on my vehicle. At the time, the car had only 1,398 miles on the odometer and had been purchased just one month prior. Shortly after the warning appeared, I received a diagnostic report from OnStar indicating fault code U362A. The vehicle exhibited significantly reduced acceleration and limited charging capability. Concerned about the issue, I brought the car to the dealership where I purchased it for inspection and service. The dealership performed a reset of the main computer system, which cleared the warning light. However, I remain concerned about the reliability of the vehicle. If this issue were to occur again—especially while driving in a remote area—I could be left stranded without the ability to drive or charge the car. While the problem has not resurfaced since the reset, I am worried it may return unexpectedly, affecting my confidence in taking the vehicle on longer trips.

I leased this vehicle approximately three weeks ago, yesterday as I was adjusting the dashboard lighting, the service high voltage battery warning came on. Now the vehicle wont take a charge, the vehicle has changed the charge setting to 40%, and I cannot increase it. I 've reserved an appointment for 4/11/2025 for the vehicle to be serviced, and was told that I wont be given a loaner vehicle. This entire scenario is very inconvenient to say the least. This my first Honda and probably my last. I feel that my safety is at risk in this case, as I cant drive it now, since I cant recharge the battery, so the vehicle is totally unreliable at this time. There were no warning signs of this issue, and I'm grateful that the vehicle didnt die in the middle of rush hour traffic, or leave me stranded somewhere.

I was driving and a warning popped up on my dashboard screen telling me that the "high voltage electrical system needed to be serviced" and another one followed that said "acceleration reduced drive with caution." At the same time my heat stopped working and only cold air would blow from the vents (it was a cold day so I did not test to see if the A/C was also broken). I discovered a day or so later, when I went to charge my car (it is an EV) that it would not allow me to charge above 26% capacity.

After updating my Prologue and driving it for a few miles, I'm now seeing a message that says: "Service High Voltage System / Service vehicle soon." The car will not accept a charge at all and the heat/defroster will not work. It will only blow cold air (which may just be outside air circulating meaning full hvac isn’t working).

When starting vehicle, lights for Propulsion Power is Limited lights and service vehicle soon lights came on. I tried to shift into reverse, but got a warning message that the conditions for shifting error, I also could not shift to drive. I only have had the car for 2 weeks. I called the honda warranty, they arranged to have it towed to dealership. 2 different service people tried troubleshooting the problem on site with no success. It was towed and dropped off after hours at a Honda service center. The tech called the next day stating that the problem could not be recreated and all diagnostic tests came out good. Waiting and wondering when this car is going to leave me stranded again.

Hackettstown, NJ
FUEL/PROPULSION SYSTEM
When accelerating into a turn from a complete stop, left turn or right turn, there is a knocking sound coming from the cv joint. Vehicle made this sound when driving off the lot brand new. Vehicle also experienced a battery fault error/reduced propulsion warning at 700 miles and is currently at the dealer to investigate. The error alternates with the battery fault light indicating a fault with the high voltage battery and the propulsion power is limited light. This error occurred after preconditioning at 30% battery charge in 32 degree weather. The vehicle warmed up the interior but displayed the message as soon as I put the car into reverse gear. Both of these issues are safety issues in potential loss of steering and loss of propulsion power on the road.
