I have had two safety issues with this vehicle where there were system failures that did not record DTC codes. And an additional failure that does not record codes and cannot be duplicated. After leasing the vehicle for seventeen months, and during repair for an unrelated non-safety issue, it was discovered that the steering wheel airbag had a loose connection. No warning appeared at any time on the instrument panels. As well the one pedal function would switch into regular drive mode, as in a gas powered vehicle, randomly. After multiple tries and incidents the dealer service department has been unable to duplicate. Then on March 6 of this year I bought in the vehicle yet again for this one pedal failure, and was notified there was an existing recall. This software update was performed. On March 17, just 11 days after the update, while backing into my garage with the garage door going up the windshield wiper was clipped by the door, destroying both the wiper and shattering the back window. I have backed into my garage thousands of times and never had an issue. Why this happened on this date I do not know. What I do know is that the vehicle gave no warnings and did not break for the object. At the time my dogs were clipped into their seat belt harnesses in the center well. By a miracle no glass shattered beyond the back storage area and I was able to safely remove them. I checked after and all of the collision warning systems were listed as active, including automatic braking for rear collisions. I had the dealership run scans twice and all scans showed no DTC codes and all systems active. I can only assume that all prior updates have failed, and there is a substantial defect to the vehicles ability to communicate. I have a copy of the scan performed. The second scan was run on April 9 because the dealership failed to provide a printed copy of the first. I have that second scan. My vehicle fails to communicate or activate essential information, a safety hazard.

On April 5, 2026, I was stopped at a busy intersection waiting to turn left. When I proceeded through the light, the car's sensor suddenly went off and the car braked violently. I thought I had hit something in the road. (I was driving in one pedal mode). There was nothing in the road, and I had not collided with anything. The car just decided to brake because it incorrectly sensed something in my way. I was almost rear ended, and it was very frightening. My safety was at risk as well as the person behind me. I have an appointment with the service department at the dealership to address it. This car has been in for service 5 times in the 18 months I have leased it. I have complained to the dealer multiple times, and they have basically ignored me.

NHTSA ODI 11729593

The issues I am experiencing for approximately the past five to six months include:- Forward Collision System showing the message “Forward Collision System Unavailable.” Adaptive Cruise Control displaying “Adaptive Cruise Temporarily Unavailable.” Rear parking safety system applying sudden braking even when there is no pedestrian, vehicle, or object nearby. Even when the system is set to “Alert Only,” the vehicle still applies the brake unexpectedly.

NHTSA ODI 11724496

On multiple occasions the alert for either the forward or rear collision warning system will sound with nothing either in front of or behind the vehicle. In these cases, the car automatically braked and brought the car to a stop in the middle of my driving. The component is not available for inspection. This puts myself and others at risk by completely overriding my ability to control the vehicle until I am able to put the car back in gear and begin moving again. It completely immobilizes the car for several seconds. It is also a safety hazard because I have been forced to turn off the automatic braking for both the front and rear collision warning systems. This problem has not been confirmed by the dealer, nor have any of the parts been inspected by those listed above. There were no warnings or messages before the problem began.

NHTSA ODI 11717745

Every day when backing out of the driveway the car activates the rear emergency breaks as it “sees” my neighbors parked truck across the seat. At no point is my car anywhere near th parked truck. Also, the emergency brake activates multiple times.

When turning my vehicle I hear a clicking & cracking sound in the cv joints of the car. It happens in both directions. This can be a safety issue when driving if the axial or CV joints fail. It could put myself, my family & other people on the road in danger if this happens & the joints go out or fail. NO warning lights it just happened over time. the car has only 14000 miles at the time of this complaint.

NHTSA ODI 11711569

On at least 3 occasions my car has braked automatically for no reason. Nobody was in front of me or behind me.

NHTSA ODI 11709932

The system does not reliably "see" pedestrians or cross traffic or often times will phantom brake when there are no obstacles viewable. I believe this is a substantial safety issue because the car will abruptly stop without warning and engage a parking brake, creating a delay before being able to vacate traffic. This has happened going forward, but more frequently in reverse. This appears to happen more during inclement weather or in the dark.

NHTSA ODI 11707175

The parking collision warning will alert and emergency brake for no reason while still several feet from anything near the Prologue. This was demonstrated for and confirmed by the dealership. Then they shrugged and said that Honda has not issued a fix for the problem. This is a safety issue because the sudden emergency brake has nearly caused collisions and has covered me in scalding coffee multiple times.

1. Parking sensors will go off at the most random times. The most common is when I’m at a standstill at a traffic light and the front parking sensors will start beeping as if I am as close as possible or about to hit an o next in front of me. 2. Rear parking sensors consistently alert and beep when there is nothing behind me. For instance I was backing out of a parking spot with no cross traffic or anything behind me. As I was trying to back out it slammed the breaks and came to a sudden stop. It did this again until I pulled the car back into the parking spot and backed out again. This will also happen when I am backing the car into and out of my garage. I don’t have anything beside me or within the guide lines but it will out of nowhere come to a sudden stop and not let me back up anymore. 3. I had one instance of emergency breaking. We were coming to a stop when out of nowhere the emergency breaking stopped the vehicle. We were at a slow rate of speed at this time. Maybe 10mph when it slammed the breaks on to come to a complete stop about 10 yards behind the vehicle in front of me. It did this twice within a few second period causing a motorist behind me to almost hit me.

cuando obtuve el vehiculo a los 5 meses comenso con un golpeteo al girar el volante lo lleve al consecionario y me dijeron que tenia que cambiarle una pieza pero que no la tenian que tocaba esperar un tiempo. pregunte si no habia ningun problema y me dijeron que no que podia seguir conduciendo asi el vehiculo. yo lo lleve en el mes de enero y hasta el mes de abril me llamaron para decirme que la pieza habia llegado. esto me puso en riesgo porque ese golpe cada vez es mas fuerte. alguien externo me dijo que eso era muy peligroso andar asi porque me puedo quedar sin direccion en cualquier momento. el vehiculo nunca me dio una luz de advertencia.mi segungo problema es que cuando voy conduciendo el vehiculo frena bruscamente como si detectara algo en la carretera este es muy sensible y me parese peligroso porque si esto me lo hace en una via de alta velocidad puede causar un accidente, lo mismo pasa cuando doy reversa. este problema no lo he puesto en conocimiento de nadie

When going in reverse my Prologue will slam on the brakes even when there is nothing behind me.

Anti-Braking System (ABS): The Anti-Braking System (ABS) malfunctioned, causing the car to unexpectedly slam on the brakes multiple times while backing up. This issue is likely related to a failure in the ABS sensors or control module. The component is available for inspection and was reported to the dealer. Transmission (Shifting into Neutral): The transmission failed by unexpectedly shifting into neutral while driving, preventing acceleration. This issue is likely related to a malfunction in the transmission control module (TCM) or related sensors. This component is available for inspection and was reported to the dealer. Anti-Braking System (ABS): This malfunction posed a significant safety risk. The car unexpectedly slamming on the brakes while backing out of the driveway onto the road causes a sudden stop, potentially leading to a collision with other vehicles as it takes several attempts of hitting the brakes or turning the emergency brake off to get the car to continue reversing out of the driveway. Transmission (Shifting into Neutral): This issue is extremely dangerous, especially on busy roads. When the vehicle unexpectedly shifted into neutral, I was unable to accelerate, which could have resulted in a dangerous situation if it had occurred on a highway or in heavy traffic, putting my family’s safety at risk. Both problems have been reported and inspected by the dealership but they were unable to reproduce the issues. I was told the auto braking system is performing as expected and is in the user manual and cannot be turned off which does not seem right. I have never driven a vehicle that cannot back out of a driveway without interruption. The Auto Braking System does display a message of "Rear Cross Traffic Auto Braking" when the brakes are initiated.

When I turn left or right from a complete stop it makes a clicking noise. I believe it is the CV joints. I brought it into Honda for them to look at. They know about the issue but don't have a fix for it and will not do anything for it. When backing you the car randomly puts on the break with nothing around the rear of the vehicle.

NHTSA ODI 11651771

I have two problems: 1. When I steer full left or right and move forward, I have clicking noise coming from the front. 2. Usually when I push break, my car gets into emergency brake .I guess the sensors are too sensitive and it gets into emergency break and stop the car without no reason.

NHTSA ODI 11650180

All ADAS systems have to be turned off. Even if switched to alert only the vehicle will randomly break very hard while driving. Also will randomly not allow you to back out of your garage. Or when raining will not allow you back up.

I've had to turn off all the safety features in my car on multiple occasions. I nearly got hit by several cars turning into driveways because the car's sensors detected a vehicle on the driveway. Additionally, the sensors mistakenly detected another car pulling out of a shopping center, which caused heavy brake locking. This has even happened to me twice on the freeway. When I mentioned this to the service manager, he laughed and said, "I know what you're talking about. I have one too, and it happens to me as well. Unfortunately, there's nothing we can do about it except turn off the sensors." And be careful with your neck the ways brakes lock in

The car makes a clicking noise when I make sharp turns, most co.monly to the left. It is brand new with only 2320 miles on it. The noise started within the last few weeks. The rear breaking system locked up the brakes and turns the emergency break on, when backing up, even if nothing is behind me. Once it was rain drops dripping off of the rear window. Another time, nothing was there. I had to assume that it picked up a shadow in the driveway.

NHTSA ODI 11642088

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.
