FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
While approaching a red light on a busy road the forward alert triggered and auto breaking was engaged with no vehicle in front. Almost resulted in an accident. Had the light not been red other cars near me may not have been breaking.

ELECTRICAL SYSTEM
I bought my car in mid-December and twice in the space of driving it less than 300 miles I got warning lights regarding a "high voltage" problem and to go to the dealer immediately. I did both times. The first time they said it was due to the robot installing some valves backward and also the refrigerant was low. They put me back on the road and it happened again after a few short drives. My car has been in the shop ever since. It is now Feb. 10. They now say that there is a badly designed hose that leaks refrigerant, and they are waiting for it to be redesigned and sent out and it is on national backorder. They estimate it should become available by end of February. I want this complaint logged into the system in case it happens again and because I am sure many people have this problem, having read all the complaints on the Honda Prologue forum online.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: WARNINGS
I have encountered recurring problems with the vehicle's automatic braking system, as well as issues with the Honda Prologue app, both of which I believe compromise the vehicle's safety and performance. The vehicle's automatic braking system appears to be malfunctioning, as it has activated unexpectedly on multiple occasions, leading to near-miss accidents. At least three occasions, the vehicle’s brakes have engaged without cause, even in situations where there is no obstruction or “phantom” vehicle detected. This automatic braking has not only been inappropriate but also posed a significant safety risk to both myself and other road users. Additionally, the reverse braking system exhibits similar issues, activating without cause. Despite the alerts being on and the brakes not being engaged, the system’s warning signals still activate, leading to further confusion and potential danger. I have consulted with both the dealership and the Honda Prologue forum, and it has been confirmed that this is an ongoing issue. The dealership has indicated that they have no immediate workaround or solution. The only remedy has been to disable these safety features entirely, which negates the very purpose of having them.  The Honda Prologue app, which is intended to provide critical vehicle information and allow remote monitoring and control, is also malfunctioning. I have been in communication with Honda for over two months regarding these issues, but unfortunately, no viable solution has been provided. The app is essential for monitoring vehicle functions such as theft prevention, charging status, and temperature control, all of which are key safety and convenience features. In particular, I am concerned about my ability to monitor the vehicle’s charging especially given the increasing number of incidents involving electric vehicles catching fire during or after charging. Proper monitoring of charging status is crucial to avoid potential overcharging and battery degradation.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, SUSPENSION
As others have reported here and elsewhere online, my Prologue emergency braking/collision detection system repeatedly activates when there is no danger of a collision. Backing out of my driveway I can expect that 25-50% of the time the car will slam on the brakes for no reason and apply the parking brake, which I then have to disengage manually to continue backing out. More recently, I was driving 30 mph on a city street with no one in front of me when without warning the Prologue slammed to a complete stop. Fortunately no one was behind me or I almost certainly would have been rear-ended. After four months of owning the Prologue, and seeing this exact problem reported over and over again, it's evident the entire electronics system is glitchy at best and downright dangerous at worst. Everything from the crash-avoidance cameras (regularly issues messages that they're blocked when they're obviously not) to the remote starter (supposed to come on with two quick presses of a button on the fob, but often takes a dozen or more to actually activate) is borderline non-functional. Whether this is a software or a hardware problem, or some combination thereof, there's no question in my mind that sooner or later, as more of these vehicles are on the road, one of these malfunctions is going to cause a crash. I hope the NHTSA will see enough of a quorum of similar complaints to investigate before that happens. For my part, I've turned off all driver assist systems in my Prologue, which is the only way I can be assured the car will only brake when it should. Additionally, again as many others have reported, my Prologue knocks somewhere in the vicinity of the front axle whenever I corner sharply enough in either direction.

SUSPENSION, STEERING
The car makes a clicking noise when I turn. It is brand new with only 1100 miles on it. The noise started within the last few weeks. While the dealer claimed the car is safe to drive, I am concerned a part may fail while I am on the road.

VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
I was driving on the freeway when a few error lights came on—the Reduced Acceleration, Propulsion System Icon, and a turtle icon on the dashboard and I had to floor the accelerator pedal to maintain my speed. I then pulled over, and the vehicle wouldn’t shift into drive or reverse. It gave an error message saying “conditions not meet.” Eventually, the car started working again. This is an ongoing issue with the car and Honda doesn’t want to do a buyback, this car is a lemon. I keep taking it to the dealer and all they do is clear the codes and state they can’t “duplicate” any of my concerns.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Twice, a "service high voltage" error light has come on and it has said it impacts the ADAS and safety systems and the acceleration of the vehicle. The light disappeared after a short drive, but the heating system stopped working. The first time, we took it to the dealership and they reset the system and the heat came back a little, but seems to struggle under 32 degrees, and especially sub 15/20 degrees. The second time was this morning - the heat is barely working at all. Very frustrating for a vehicle under 2000 miles.

ELECTRICAL SYSTEM
I purchased Honda Prologue Elite Model in May 2024. In around December, a warning sign "Service High Voltage System" message showed up. We left the EV for service twice since then and the first time the honda dealer mentioned that the A/C and Battery Sensors were in swapped positions and they fixed the issue by swapping positions and was set right. The warning came back again around two weeks later and the 2nd time around, they said the DTC P0534 A/C Charge was low and that this error must have happened at assembly. The warning disappeared for less than 2 weeks and reappeared again the 3rd time. Its about 4 weeks now since we have left it for service and when we called them couple of times, they mentioned they are waiting for the parts from Honda and dont have an ETA. Its 4 weeks and we do not have the vehicle after investing 60K. We made several calls and emails to American Honda Motor Co., Inc asking for update on the Issue and the inconvenience we are facing without having the car and the response is to wait until they can fix it. This is not expected from Honda whom we trusted and bought such an expensive car. It seems like they don'w know what the real issue is and each time we get some random response as a fix and the issue comes back. What's more concerning is that its an issue with the Electrical High Voltage system and we don't feel safe driving in it. I would have not chosen to by this EV if i knew they had these issues and not tested well enough before releasing for public. I have lost faith in Honda and 60K isn't small money Hoping the concerned office will Look into these reported issues and address this soon. Best

ELECTRICAL SYSTEM
Twice in the total 750 mileage on the Prologue, warnings have come on that state “Service High Voltage System" and "Reduced Acceleration Drive with Care.” This occurred on 01/03/2025 at ~300 miles and again on 02/02/2025 ~750 miles. This error seems to be widespread with low-mileage Prologues, but Honda does not appear to be recalling to correct.

I purchased the vehicle on January 27, 2025. The morning of Jan 29th, I had three error messages pop up. 1- Service High Voltage System 2- Service Vehicle Soon 3- Reduced Acceleration Drive With Cate The vehicle would not allow me to connect via Bluetooth. My phone was no longer paired. I took immediately to the service dept at the dealership where I purchased the vehicle. Was told it was an issue with the AC, an A/C pressure valve would need to be ordered. 7-10 days for part to come in. Vehicle is in service dept waiting to be repaired. Only 79 miles on the odometer.

show a "Service High Voltage System" message. The Honda Prologue we purchased in May 2024. We have left it with the dealership for the 3rd time now and problem kept coming back. As a first time EV user we are concerned of safety and ofcourse not knowing what is happening. The 2nd time around, I was told the DTC P0534 A/C Charge was low. This condition was not detected the first time this alert showed up. I was told that the A/C and Battery Sensors were in swapped position (ie wrongly swapped positions) and that this error must have happened at assembly. I have dropped off my EV at Dealership on Jan-9th and today is 31st and still haven't got any updates on it and i am without my car. No one seems to know what the issue is really and randomly suggest somethings and problem comes back again.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
Propulsion System Failure light came on and vehicle lost all cabin heat. This occurred in winter (January) and since there is no heat all vehicle windows fog over, obscuring the view of the road and other drivers. All vehicle occupants are also at risk of exposure due to complete lack of heating in sub-freezing January temperatures.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
After using the turn signal, instead of self-cancelling it will operate turn signals in the opposite direction for several flashes and then cancel. Since the turn signal over cancels it causes an increased risk of collision with other drivers who could easily misinterpret intended action.
