2024 Honda Prologue

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.

I have had multiple issues with this vehicle and it has been in the shop more than 80 days between April and Oct 2025. First, the entire battery system went out in the all electric vehicle. Honda said that since it was a collaboration car with GM, that it would take a long time to fix because their technicians weren’t very familiar. It took almost 8 weeks in the shop before we got it back. Not long after, the entire dash (electronics) went out and the shop had it again for over a week. they never found or could replicate the issue. The vehicle went back in after having multiple incidents of emergency braking when there was no emergency, or even vehicles in my vicinity. The final time this happened, I was traveling nearly 25 miles per hour and the car decided to slam on the brakes, making me feel like I hit a brick wall. My head slammed the steering wheel and my daughter was terrified. I drove it straight to the dealership and they said “what’s wrong with the car this time”…they had it for weeks, couldn’t replicate the issue and tell me it’s fine and to take it home. They suggest TURNING OFF THE SAFETY STSTEM AS A FIX, which seems criminal. The safety features should work properly. I shouldn’t be instructed to turn them off. I am very frustrated and have been working with Honda on a buy back out of good faith, but it’s been weeks and we have no answer. I am forced to drive a gas vehicle, costing me gas money now, when I bought an electric vehicle to avoid this cost. All around, it has cost me more money than it’s been worth and I’ve made multiple car payments as it’s sat at a dealership unusable. Again, it has spent more than 80 days in 6 months at the dealer with no resolution. My sound system blew out last time they had it checking out the braking issue so I waited another week to have that replaced, meanwhile the fix to the braking system was that I was told to turn the safety feature off. Insane

I got several false positives from the radar or perhaps optical system that caused the vehicle to spontaneously and suddenly brake at freeway speeds. I believe it was the optical system that was at fault due to the shifting lines on the freeway but I can't be sure. I got the radio update service bulletin work completed by the dealership and it seems to have abated. However, any 2024 prologue that has not received the update is subject to the same error. From what I understand, Honda has stopped performing the service bulletin at this time due to update failures that have "bricked" the car's software.

the automatic emergency braking system in both forward and reverse is to sensitive and violently slams the brakes when there is no risk of a collision. the most recent incident involved making a left hand turn where there was a little overpass wall on the passenger side of the street i was turning onto. with cars behind me the vehicle slammed the brakes as i was going approx 10-15MPH , startling myself and all 3 passengers and almost causing me to be rear ended. the vehicle also slams the brakes in reverse when there are no objects in the way predominately if it is raining out. it's a harsh violent stop and can cause an accident or injury. due to this incident the vehicle is back at the dealership for a total of 3 appointments and 32 days in repair for this issue and they still have not remedied the issue

My 2024 Honda Prologue has numerous issues. First, the CV joints are making the clattering noises when turning right from a stop. Started at almost 8000 miles, more faintly, but now very noticeable. I noticed the left has now started making the same noises as well at 9000 miles on the odometer. Soon after purchase, the automatic braking/collision avoidance slammed on my brakes HARD while driving at highway speeds. Nothing was present in front of me, early morning and no cars around or I probably would have been rear ended for sure. I disabled the auto braking but the “BRAKE” alert comes on almost daily, with nothing there. Backing up did the same so I disabled it as well. Lastly, every time I use my turn signal to turn right and I bring the wheel back to center, it cancels out as it should but it then turns the left signal on for 3 blinks. Assuming the stalk is to strong or weak and goes back just far enough to indicate like I am going to turn or enter left. This can surly cause confusion to other drivers. The dealer stated Honda is aware of the CV noise but has no remedy at this time. For the other issues, they needed me to leave my car but had no loaner available. I will have to return there at another time as the loaners are “first come first served”.

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.

Frequently engages erroneously due to heavy rain or pavement markings. Last week when it was raining heavily, AEB engaged at least 10 times while I tried to back out of my garage (there was nothing/nobody in my driveway). And this past Friday it engaged 3 times on different colorings for patched pavement cracks in a parking lot while backing out of a parking spot.
