2024 Honda Prologue

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. Attempted to connect the starlink on multiple occasions as well to no success and just a bunch of wasted time trying. In addition to all the alarming safety concerns, this car would not heat up well- 40 minutes into my ride I'd start to feel some warmth. I would love to have this case investigated further and sue honda for allowing such a dangerous vehicle on the roads. My accident was bad but the honest truth is that it could have been worse and no one should have be subject to this danger.

While driving in traffic, the car unexpectedly applied the brakes and displayed a 'Service High Voltage System' warning on the dashboard. Shortly after, another message appeared: 'Service Vehicle Soon,' followed by 'Reduced Acceleration - Drive with Care.' The car isn't charging and lacks the speed needed to drive on the highway.

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. Sometimes it even warns me of something that isn't even there.

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.

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.

On [XXX], around 8 PM, I was driving north towards DeLand, Florida on the highway at approximately 70+ miles per hour when my 2024 Honda Prologue started to slow down on its own. The air conditioning system shut down, and a warning displayed on the dash: “Service High Voltage System.” I immediately drove home and contacted CarSafely, fearing that the car might become stranded and was not safe to drive. The following morning (Tuesday, [XXX]), around 8 AM, I emailed and called the Coggin DeLand Honda service department, informing them of the issue and sharing photos and a video of the incident. The error/warning disappeared after turning the vehicle on and off several times. Coggin advised me to bring the car in the next time the warning appeared on my dashboard. On Thursday, [XXX], around 12 PM, I was driving on [XXX] towards Daytona Beach at around 70 mph when the vehicle suddenly slowed down again. The air conditioning system shut down, and the service warning “Service High Voltage System” appeared on my dashboard once more. I immediately got off the highway and stopped at a safe location to turn off the vehicle and document the error and warning on my dashboard. I emailed Coggin DeLand Honda again to inform them of the issue. On Friday, July 5, 2024, I took the car to the Coggin DeLand Honda service department, where they connected the vehicle to their computer for a diagnosis. The service department detected the error and reset/cleared the error code. However, the service tech informed me that they could not fix the issue due to insufficient information, as the vehicle was built by GM (General Motors Corporation). They advised me to return directly to the dealer without an appointment if the error reappeared. On Monday, [XXX], around 8 AM, while driving at approximately 25 miles per hour on a local road near my home, the “Service High Voltage System” error reappeared.
