Honda Prologue adaptive cruise problems

This is my second separate report which I experience with my car. On August of 30th, the car was unable to shift, so it was towed to Andy Mohr dealer to repair. It took 5 days for serviceman to figure out there was a wire issue. So he fixed, so he thought, on the September 9th, the same warning light came on my dashboard. I spent over a thousand dollar just serviceman to diagnose the same problem 3 times, but nothing was fixed. The warning lights are "service transmission unable to shift soon", adaptive cruise unavailable, one-pedal driving unavailable, brake hold unavailable, service emergency brake, service transmission unable to shift and more.

1st Continuous clicking sound from the front axel when trying to turn, its amplifies when taking a uturn. I have complained to Honda service center they said they are not aware of while there is already fix done at different honda service centers. 2nd the Lanes assist doesn't work as a safety feature, it has multiple issues a) it ping pongs between the lanes with sudden moves, b) most of the times at the higher speeds it only warns or tries to correct once at least one of the wheels is in another lane c) with adaptive cruise control on and lane assist not working on any curved road if you are close to the divider or near an exit, it doesn't understand that the car ahead has taken the curve and it should stick in the lane, instead it accelerates and goes of the lane and thats very dangerous.

The warning messages pop-up such as "One pedal Driving Unavailable. Use Brake for Stopping", "Auto-hold unavailable", and "adaptive cruise control temporarily unavailable " then parking sign with ranch sign turns on. And all the functions will be disable. I went to Honda dealer to fix the problem, all they said was Parking Brake Actuators. So they replace both left and right rear Brake Actuators. A week later same messages come on and recently I have new additional warning message on Dashboard. "Service Transmission Now Unable to shift soon", I went to honda dealer, of course there is no warning message show up then, so they cannot scan or nothing showed up on the scan. So they suggest that I kept driving until warning light stay on.

I own a 2024 Honda Prologue (VIN: [XXX]). Since approximately XXX, the vehicle has experienced recurring failures involving critical driver-assistance and safety systems. The problems include: • "Forward Collision System Unavailable" warnings • "Adaptive Cruise Control Temporarily Unavailable" warnings • Automatic braking while reversing when no obstacle is present • Repeated loss of confidence in the operation of safety-related driver assistance systems  The vehicle has been presented to authorized Honda service facilities approximately four times for diagnosis and repair. The vehicle has spent approximately 20 to 22 days out of service. Despite multiple repair attempts, the problems continue. The vehicle has never been involved in a collision. A prior insurance claim involved hail damage only and was repaired. I do not believe the hail damage is related to the recurring failures of the driver-assistance systems. Because these systems are intended to help avoid collisions and improve vehicle safety, I am concerned that their repeated failure may create a safety risk. The unexpected braking while reversing is particularly concerning because it occurs even when no obstacle is present. I have opened Honda Case Number 162-31526 with American Honda Motor Company and have requested assistance, including consideration of a repurchase, replacement, or other resolution. I am submitting this complaint so that the issue can be documented and reviewed as a potential safety-related defect.

I was traveling on Interstate 80 with adaptive cruise control set at 70. The cruise control normally recognizes slower cars ahead and slows or stops as necessary. I saw that cars were stopped ahead so I reduced the cruise control setting to 60 to "help" it slow down. However, we came up fast on the stopped cars and the car did not slow. I had to manually brake to avoid a collision. The car's speed was about 67 when I applied the brakes. The car acted like slowing to the new cruise control setting of 60 was overriding the collision avoidance. I recently had much of the software in the car updated due to a recall and the adaptive cruise control seems to be acting differently now. Weather was clear, around 4pm, and the roads were dry. We were Eastbound around a slight left curve (not sharp) and traffic was stopped ahead in all 5 lanes, so the system should have noticed the obstacles ahead.

WHEN I USED ADAPTIVE CRUISE CONTROL, MY CAR TENDS TO LEAN SLIGHTLY TO THE RIGHT. IT VEERS OVER A BIT AND THEN JERKS TO THE LEFT. ALL IN ALL, I CAN'T USE ADAPTIVE CRUISE CONTROL ON THE FREEWAY WITHOUT PAYING ATTENTION. IT IS GENUINELY DANGEROUS IF VEHICLES ARE DRIVING ALONGSIDE OR BEHIND ME. OTHER THING, WHEN I USED ADAPTIVE CRUISE CONTROL FOR ALMOST ONE HOUR, THEN IT SUDDENLY BECOMES INACTIVE. IF I HAVE BEEN FOLLOW ANOTHER CAR, then what should happen when it suddenly becomes inactive??? I was very lucky at that time because there was no car in front of me. After 5,000 miles, my car began to make a slight noise on the right side when I slowed down in the city. Maybe it happened in the front drive axle assemblies or the front right low arm control.

The onboard navigation and entertainment system, including both the primary dashboard/driver interface and the center console, went fully black for over 1 minute while driving on the highway. When the screen is blank, no input is available from the vehicle as to speeds, behavior of cruise control, warning systems such as lane control, front rear and side awareness, operator awareness of speed, other vehicle warnings. Bringing to dealer today. this is the 2nd time this has occurred. The first time was in December. Vehicle was brought to dealer for software update. Update “bricked” the car, and a new radio module needed to be ordered. This took about 6 weeks. Module installed, software was updated, and this was to have addressed the issue. While records may indicate that the update was not yet performed on the vehicle, it was fully updated and the vehicle (according to the dealer) is fully up to date and the recall for it has been addressed with the software update. However, the update did not address the issue. No other inspections have occurred to date. No other symptoms or warning lights.

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.

There is a serious issue with the adaptive cruise control braking when nothing is in the driving path of the vehicle. This issue happens a both slow and fast speeds creating a dangerous driving condition for myself and those around me. It happens almost daily when I use it. For instance, if I set the cruise to 25MPH and the road turns it will slow down for vehicles parked in driveways, and while going straight it will alert me to brake for parked on the left or right. While going faster like 45MPH, it has hard braked many times for vehicles outside my lane or on the side of the road. This creates a situation where people have to avoid me and is probably unexpected and scary for them and a concern of being rear ended. I have driven several vehicles with adaptive cruise control and this has been much worse than the similar issues I’ve experienced in them as well. This issue is happening consistently and on well marked roads when conditions are right where there are vehicles around stopped or in turn lanes or driving through neighborhoods for vehicles in driveways.

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.
