2024 Honda Prologue: adaptive cruise control problems

Filed Sep 12, 2026 · Driver assistance, Electrical · IN

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.

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.

The front axle makes a grinding and click sound whenever you're turning. Dealership replaced the part but then the new one just broke as well. Now Honda is refusing to replace again as they supposedly work on a fix that has been well over a year in the making now. Separate problem with the adaptive cruise control. It randomly slams on the brakes on the highway. Dealership agreed they experienced it but nothing they could do and I would just have to wait for a software update and hope it fixes the problem.

When driving with the adaptive cruise control on, the Prologue throws out an alert after it suddenly disengages the cruise control that states that the forward camera is blocked and the cruise control will disengage. The cruise control also fails to notice cars in front of the Prologue and will speed up, then will suddenly "see" the car, jam on the breaks, then the accelerator again. Also, the adaptive cruise control cannot gauge distance between cars and all following distances set for the car, whether 1, 2, or 3, are exactly the same. This has been reproduced for the dealer and confirmed as an issue with this Prologue. The dealer then shrugged and said there were no fixes from Honda yet, so there was nothing they could do. This is a huge safety issue because a sudden deceleration at highway speeds has nearly caused a half dozen accidents in the past 2 weeks alone. This issue has been reoccurring for over 1 year with multiple congerences with the dealership, all ending with the statement that Honda has not issued a fix yet.

Adaptive Cruise Control works when you set the preferred speed but won't slow down when a vehicle is in front. Tried changing gap adjustments but still not slowing down when there's a vehicle in front. It was completely working while I was driving it in the morning then in the afternoon I almost hit the vehicle in front of me due to my vehicle not slowing down.

The buttons for changing songs have not worked at random times after turning on the vehicle. Also the car has had some problems when it comes to detecting a vehicle in front causing the car to slow down when in adaptive cruise control
