2025 Honda Prologue Driver assistance Problems

I was traveling at a steady speed of 35 MPH approaching an intersection with a red traffic signal. There was a single vehicle already stopped at the light, but it was positioned a significant distance ahead of my vehicle. Without any warning, driver input, or hazard present, my vehicle initiated an uncommanded emergency braking maneuver. The vehicle forcefully decelerated from 35 MPH to a complete stop (0 MPH) in the middle of the roadway. Prior to this incident, the vehicle's forward collision system has exhibited false positive detections, frequently issuing warnings for phantom vehicles or obstacles when the road ahead was completely clear

Drop off a few days after receiving vehicle. Picked up and dropped back off the same day due to issue repeating it self after being told there was no issue. Parts were supposedly replace on one of the occasions. No real time spent on the vehicle according to invoices. 8/28/25 -9/4/25 9/4/25 - 9/15/25 9/24/25 - 10/14/25 I have brought the car in for the same problem multiple times without it being rectified. I currently have videos and pictures from when this started to this current time. There are also other customers that have the same complaints that I do. Below is a list of issues that have been going on since first complaint including continued first complaint. I do believe that this is an issue and is a danger due to the reverse camera glitching due to the screen, not being able to get out of the screen, sometimes can not leave a parking space due to the sensor says that there is something in the way where indeed there is nothing. Also can not pull out of drive way during snow due to the car automatically breaking for snow. The collision for the front is always going off when there is no need for it to go off as this can cause someone to unexpectedly stop due to this being something that is supposed to be a warning. If this could happen to the vehicle constantly without a solution then this could be connected to something much more serious. There are other issues that have gone on as well that I have slowly started to notice and pay attention to. I do believe that the amount I am paying for this car it should not have these issues with out explanation. Clearly this is common and on going. One thing can lead to another with these issues. The screen in the middle of the dashboard —- Screen goes black for no known reason Screen flashing Screen is rainbow Touch screen will not work at these times When screen is glitching you can not turn volume down or off, disconnect phone, charging port goes out. Can not back out of parking space due to sensors going off.

Happens frequently. While it has not yet caused the vehicle to fully slam on the brakes, it will occasionally flash the brake warning and apply the brakes even when there are no obstacles present. Additionally, when backing out of the driveway, the vehicle sometimes detects the road surface as an obstruction and abruptly applies the brakes. This occurs consistently in the same location, likely due to the steep angle of the driveway.

Incident

While driving with cruise control engaged, the car had a false positive for forward collision detection and slammed on the brakes at full Highway speed. After about one of second of emergency braking the car released the brakes and resumed cruise control as normal. There were NO other vehicles on the road in front or to the side of us at the time. Due to the unexpected braking, the vehicle following us almost collided into us. The event triggered just before the shadow of the bridge was on road of the underpass. I suspect it was the shadow that might have contributed to this event. However, this is not the first time the vehicle has had false positives in the forward collision detection system. We have experienced many of these, but typically at lower speeds. Generally speaking the “triple beep” and associated Heads Us Display red “brake” symbols briefly flash, then goes away without engaging the brakes automatically, again with these there are no other vehicles present. We have called two different dealers to report this and they tell us there is no associated TSB/service bulletin or recall for our vehicle and no software update for this. We tell them that GM has had several software updates for their Ultium platform with their other vehicles to fix this, but there is still nothing from Honda. There is a SB 25-051 for the 2024 prologues that would seem to address this but it’s not applicable to the 2025 according to them even though the symptoms are the same. This needs to be looked into as BOTH dealers told us that they had several other customers complaining about the same thing.

We are experiencing 2 problems. The primary issue is both front axle. CV joints are clicking and making poppy noises when you turn either right or left. secondary issue, the car is having is the. Reverse collision warning problem. It is engaging and breaking the vehicle. When there is nothing behind it, it happens constantly. And we've had to turn the feature off on the vehicle's information head unit settings to stop it from causing harsh breaking. When backing up.

Vehicle, in one-pedal-drive, began to enter an intersection from a stop sign into a left turn--mild reasonable torque applied onto a 25mph street. Vehicle entered intersection and began stuttering/slow/shaking until near/complete stop and loss of acceleration in middle of busy intersection. Traction control light illuminated briefly prior to resumption of acceleration. Road conditions were dry, slightly foggy. There was no reason for safety systems/ABS/Traction control etc. to over react. Honda dealership reported no relevant code to explain incident--which indicates vehicle also did not flag it as an aberration. Vehicle had just been at dealership day prior and received software update and reported inspection. Honda dealership will not take further action unless reproducible with error codes to tell them how to address. Specific component, electrical, or software failure reportedly unknown and remains unaddressed by Honda at this time.

Incident

Feb 27, 2026

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.

On 2 occasions (before a dealer initiated system update), without anyone in jeopardy of being hit in front of me, my vehicle suddenly and shockingly halted - I had no idea what was happening and thought someone hit me from behind. First instance I was at a 4 way stop sign at a complete stop with much traffic in all directions. I had ample distance in front of me. Second instance, I was driving through a green light at an intersection - again not close to hitting anyone and in control of my brakes and speed, and my car stopped - almost causing the person behind me to hit me!!! It was a busy intersection!!! My dealer said they did a system update for my vehicle this past weekend, but the same thing happened again today in a busy intersection. Additionally; the organice brake warning randomly appears on my main control panel for no reason - when I have ample clear runway ahead of me!!! I am shook and so not feel safe in this vehicle. My elderly mother in law as a passenger on one of the instances nearly had a heart attack!!

The infotainment system screens go black sometimes for no reason. Been to the dealer to fix and they said they can’t duplicate the issue. Yet I have pictures and videos to prove it. The drivers assist systems turn themselves off when there is nothing blocking the cameras. Causing the one pedal driving to start applying the brakes and almost causing me to be rear ended multiple times. The AWD system is horrible. The traction control will turn on with cruise set and completely dry roads. But when it’s actively raining it slips and slides and hydroplanes do without activating any system to counteract it. The charger door was broken when I bought the vehicle and had to have it replaced. The charger itself sometimes says it can’t charge for some reason and I have to unplug it and plug it back in. The heater doesn’t get warm unless cranked to the highest setting otherwise it blows colder air. The dealership I took it to literally said they don’t want me to bring it in there anymore and to go to another dealership because and I quote “those guys know nothing about EVs so fuck them go to another dealership” the next closest dealership is 2 hours away and I work full time including weekends. So tell me how I’m supposed to make that work? The charger is now having an issue where it doesn’t charge and I have to remove the charger and plug it back in.

Unknown electrical issue in the cold. Saw posts online about people getting "High voltage system" errors and after a few days in the cold it happened to me. Dealership couldn't find the issue and simply cleared the error codes telling me to come back in if it happens again. Huge issue, as it limits the range to protect the system from further issues but doesn't give me enough range to even drive home from work if the errors appears during my commute. Occasionally my front sensors don't work but give no indication of any issues, other times it notifies me that they need cleaned, but not always. Not reliable enough to trust in anything but perfect circumstances. I am also getting the CV joint clicking issue occasionally when turning, unsure if related to cold weather or not but it has only happened in 10-20 degree weather. Sounds very bad when it occurs, not very reassuring when driving a car with less than 6000 miles on it.

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.

I recently purchased a 2025 Honda Prologue. I've had multiple issues with the advanced driver assistance systems. The rear automatic braking will slam the brakes on when I'm backing up if it detects something like a pedestrian on the sidewalk (that I am in no danger of hitting). I've also had issues with it misinterpreting where the lane lines are on the freeway, and automatically trying to incorrectly steer the car OUT of the lane, which is very dangerous, especially at freeway speeds. These systems can be disabled, but this must be done EVERY time you start the car. There is no way to completely turn them off and have them stay off. While I understand these systems were designed to improve safety, they are deeply flawed and actually make driving less safe. At the very least, there needs to be a way to permanently disable them. NHTSA needs to mandate that car companies, including Honda, offer drivers a choice to permanently disable these systems until the technology is much better than it currently is. Thank you.

Multiple times, my REAR collision automatic braking has activated when in reverse while barely moving and the vehicle was not at risk of collision. After 2 incidents, I turned the system off. Incident 1) I was reversing into a parking spot with plenty of space and the vehicle automatically applied the brakes, aggressively. It made me think I hit something but there was nothing around the vehicle. Incident 2) I was on the street at a 4 way stop. Car turning in towards me was going to need more space, so I reversed and while inching backwards with a pedestrian on the SIDE of the vehicle walking forwards from my rear, the vehicle aggressively applied the brakes, causing my passengers to think I hit something- but again nothing around the vehicle that was at risk of being hit. It was after this second incident that I turned the system off.

My vehicle recently began displaying the error messages “Service High-Voltage System” and “Reduced Acceleration – Drive With Care.” Since these warnings appeared, my vehicle’s heating system no longer works at all. This defect creates multiple serious safety hazards: 1.No heat in cold weather: Temperatures in my area are currently around 42°F, and the cabin cannot warm up. This creates an unsafe temperature environment for myself and especially for my children while driving. 2.No ability to defrost windows: Without heat, the vehicle cannot defog or defrost the windshield or windows. This severely impacts visibility and creates a dangerous driving condition. 3.Reduced acceleration: The vehicle warns of reduced performance, which may affect my ability to safely merge, change lanes, or respond to traffic conditions. These issues began without warning, and the loss of heating combined with high-voltage system errors makes me concerned about a potential electrical or battery system failure. This is a significant safety concern that needs to be investigated, as the vehicle is not safe to operate in its current state. I request that NHTSA look into this issue, as other owners have reported experiencing this same dangerous combination of high-voltage errors and loss of essential climate-control functions with no resolution from the manufacturer.

My 2025 Honda Prologue Touring, purchased in August and currently with only 7,000 miles, is experiencing multiple serious safety issues. The vehicle has already had both the left and right axles replaced. by warranty Now, the left axle is failing again. A defective axle can break at high speeds, which puts my entire family at risk, including my baby. This issue compromises vehicle stability and could easily lead to a serious accident. Additionally, the vehicle’s collision mitigation system activates unexpectedly, causing the car to brake on its own without any obstacle present. This sudden braking is extremely dangerous, especially on the highway, as it could result in a rear-end collision. The blind-spot indicators also activate at random. When I attempt to turn right or left, the blind-spot warning turns on even when I double-check and confirm that there are no vehicles anywhere near me. This creates confusion and hesitation while driving, increasing the risk of a crash. Given the repeated axle failures, unintended braking, and malfunctioning blind-spot monitoring system, I believe the vehicle presents significant safety defects that require investigation.
