2024 Honda Prologue Acceleration Problems

Owner reports

Selected complaints filed with NHTSA by 2024 Honda Prologue owners, lightly cleaned up (personal details are redacted by NHTSA).

Break failure on highway causing MVA- multiple attempts were made to slow down and break vehicle to no response what so ever. Pressed breaks all the way down, nothing, no air, no resistance, no sounds, vehicle kept on going. In an attempt to save myself from an accident that could have been much worse, I jumped out of the moving vehicle, landing the back of my head on the cement highway floor toward left end of bumper. This vehicle is not safe and should be taken off the roads. I have 2 toddlers and am traumatized. The vehicle stopped after some impact in the middle of the highway. From the moment of receiving this car there has been some sort of issue with it's breaks. Initially short stopping on it's own when gas peddle not pressed- had the setting fixed for that to then experience multiple whiplashes for no reason while driving. …

It seems that the vehicles "auto hold" function, which is the standard control method for electric one-pedal driving cars does not always operate correctly or at all. This results in the vehicle suddenly accelerating due to gravity or potentially under it's own power. I have had to slam on the break many times to prevent the vehicle from busting through the garage door, and if any of my children or anyone else was near the car they could certainly receive life-threatening injuries. The vehicle has been bought in for this and a slew of other issues, and the service center relied on a software update and us testing the vehicle thereafter for the reported faults. The vehicle has been inspected by the Honda dealership's EV expert. There are no warning lights, alerts or any preceding messages that would suggest there was an issue. …

The center display and instrument cluster on my 2024 Honda Prologue fail intermittently while driving. When the instrument cluster drops out, I lose the speedometer and driver information display. When the center display fails, the backup camera image is unavailable, along with audio and climate information. On July 24th, while driving at approximately 45 mph near Keuka Park with my family in the vehicle, the center display went black. Minutes later, the instrument cluster cut out and recovered three separate times. I recorded video of the display failure and two of the cluster dropouts. The problem began at 868 miles, about three weeks after delivery in April 2025. Dealers replaced the touch screen audio unit in May 2025 and the radio control assembly and infotainment module in June 2025. The problem returned. …

I wanted to register a complaint on an issue we have experienced in our 2024 Honda Prologue EX Elite with the "CV axles." This vehicle was sold to us with like-new mileage and was also certified, pre-owned by Honda. Symptoms of the problem were knocking sounds heard from the lower, front section of the car when accelerating from a stop and turning at the same time. It was first noticed around 4000 miles and diagnosed by the local Honda dealer at around 7300 miles. Based on many blog postings about consumer experiences with this issue, I believe it would have been difficult for Honda to unknowingly sell this car with this as a design defect, and it does not have a fix other than replacing with the same part which is prone to failure. Again, this claim can be backed up by many other consumer postings which reference defective CV axles being replaced multiple times. …

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. …

I have had my prologue for about two months now and have noticed that I receive a warning about reduced acceleration "randomly." I say "randomly" because I've observed that it appears during two specific situations. I get that warning whenever I'm low (less than 20%), so this is not random as it seems consistent. The other time this occurs is when I am driving or just starting my car (the battery percentage doesn't matter, as it happens when it's between 30% and 80%. Also, it happens when the temperature is below and above freezing). However, the latter situation occurs randomly and seems to happen more frequently while driving, though it also occurs when I am just starting the car. On top of that, the Forward Collision Warning system is extremely sensitive and has caused the car to brake hard unnecessarily on me with and without Adaptive Cruise Control enabled. …

SEVERAL LIGHTS BEGAN FLASHING, AND THE ACCELERATION stopped at 25 mph: 1. Service High voltage 2. Service Vehicle Soon 3. Reduced Acceleration - Drive With Care I brought the car in the next day. The service center at Honda Mahwah diagnosed the problem immediately. They said it is a valve for the AC system that cools the battery. They know this valve is bad on many Honda Prolouges and needs to be replaced. They said there is a "Service Bulletin" out for this problem. Then they said they do not have this valve and have no idea when it will be available. They did not want my car to sit on their lot, nor did they offer a loaner. I have not driven the car since, and it sits in my driveway, not the garage. I'm afraid of the high voltage problem, and I do not want the battery to explode in my garage. I think the NHTSA should issue a recall so this can be fixed. Pictures attached.

On 13 August 2024 I was driving my 2024 Honda Prologue when the DIC and infotainment screens went blank. At this time with no information displayed on any screen, the car was unsafe to operate. I drove the car straight to the local dealer, Tony Honda. The dealer was unable to diagnose the problem. After contacting Honda Tech support, they decided the audio control unit was defective. After 65 days the dealer was able to replace the unit and it seems to work properly. Honda informed the dealer the car was safe to operate without any display screens or information. Actually the car was unsafe to drive with no speedometer indication or any other control functioning.

I was driving on the freeway when a few error lights came on-the Reduced Acceleration, Propulsion System Icon, and a turtle icon on the dashboard and I had to floor the accelerator pedal to maintain my speed. I then pulled over, and the vehicle wouldn't shift into drive or reverse. It gave an error message saying "conditions not meet." Eventually, the car started working again. This is an ongoing issue with the car and Honda doesn't want to do a buyback, this car is a lemon. I keep taking it to the dealer and all they do is clear the codes and state they can't "duplicate" any of my concerns.
