There are 7 owner-reported speed control & cruise complaints for the 2024 Honda Prologuein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
According to my research the part that has failed in the CV joint for my right front wheel. This was made evident to me by an occasional clicking noise when I turn and accelerate. The part is not available for inspection. So far, it has not put myself or others at risk. The problem has not been confirmed by a dealer. Neither the vehicle nor the component has been inspected by those you listed above. There have been no warnings or other symptoms before the CV joint failed and the clicking noise began.
Anti-Braking System (ABS): The Anti-Braking System (ABS) malfunctioned, causing the car to unexpectedly slam on the brakes multiple times while backing up. This issue is likely related to a failure in the ABS sensors or control module. The component is available for inspection and was reported to the dealer. Transmission (Shifting into Neutral): The transmission failed by unexpectedly shifting into neutral while driving, preventing acceleration. This issue is likely related to a malfunction in the transmission control module (TCM) or related sensors. This component is available for inspection and was reported to the dealer. Anti-Braking System (ABS): This malfunction posed a significant safety risk. The car unexpectedly slamming on the brakes while backing out of the driveway onto the road causes a sudden stop, potentially leading to a collision with other vehicles as it takes several attempts of hitting the brakes or turning the emergency brake off to get the car to continue reversing out of the driveway. Transmission (Shifting into Neutral): This issue is extremely dangerous, especially on busy roads. When the vehicle unexpectedly shifted into neutral, I was unable to accelerate, which could have resulted in a dangerous situation if it had occurred on a highway or in heavy traffic, putting my family’s safety at risk. Both problems have been reported and inspected by the dealership but they were unable to reproduce the issues. I was told the auto braking system is performing as expected and is in the user manual and cannot be turned off which does not seem right. I have never driven a vehicle that cannot back out of a driveway without interruption. The Auto Braking System does display a message of "Rear Cross Traffic Auto Braking" when the brakes are initiated.
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. We have not been driving the vehicle due to the these obvious safety issues. When we were driving this vehicle both drivers and the kids in the car quickly became aware of the issue and all felt unsafe. The vehicle has remained parked and unused. Recently I was able to test this and recorded videos of the seemingly random, obviously unsafe and seemingly random events. I cannot seem to upload these videos to this portal.
Service High Voltage System Reduced Acceleration - Drive with Care Service Vehicle Soon There is a very prevalent problem with the new EV Honda Prologues. Mine has been in the shop since last Friday, Jan. 17. The parts "are on backorder" with Honda refusing to state how long it will take for parts to come in.
The forward collision sensor failed to work after 2500 miles, disabling my ability to use adaptive cruise control. I've thoroughly cleaned the area where the two sensors are and it made no difference.
Car will stop abruptly even when simply reversing out of my garage when there are no obstacles behind me. This poses a safety risk to me and others. Car has not been inspected. I was told by the dealer this is a known complaint. No warning lights or messages.
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.
