2024 Honda Prologue

Direct cause - Unknown. What I do know however was that the automatic emergency break system on my vehicle was activated, causing the vehicle to stop in the middle of driving. This resulted in the vehicle behind me hitting my car. Prior to the incident occurring, no warning indicators (lamps, messages, etc.) came from the dashboard. The vehicle just stopped. Immediately after this accident occurred. I turned off the forward collision safety feature, as I was scared of the issue (vehicle stopping) repeating itself. To date, my vehicle has not been repaired or my insurance agency contacted, as I do not believe I should be held responsible for the cost of this repair.

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.

On 2/19/2026 I was taking an freeway exit ramp from I 15 south to Carrol Carrol canyon and I stepped on the brake but the car did not slow (my perception was it was speeding up), the vehicle collision warning did not sound and the vehicle did not emergency brake, therefore I hit a stopped vehicle at a stoplight. The air bags did not deploy. Attached pictures: Left side is the vehicle was rear ended. Right side is the Honda Prologue

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.

Clicking noises when turning. Dealership no longer fixing (fixed passenger side, driver side still unrepaired). Front end collision breaking happening at random, causing unsafe breaking in the middle of the road. Also frequently happening when releasing break at stop light, narrowly avoiding multiple rear end collisions due to breaks being slammed on by vehicle collision system. Now with high voltage battery failure message, blowing cold air out of hvac system and performing at reduced acceleration.

On multiple occasions the alert for either the forward or rear collision warning system will sound with nothing either in front of or behind the vehicle. In these cases, the car automatically braked and brought the car to a stop in the middle of my driving. The component is not available for inspection. This puts myself and others at risk by completely overriding my ability to control the vehicle until I am able to put the car back in gear and begin moving again. It completely immobilizes the car for several seconds. It is also a safety hazard because I have been forced to turn off the automatic braking for both the front and rear collision warning systems. This problem has not been confirmed by the dealer, nor have any of the parts been inspected by those listed above. There were no warnings or messages before the problem began.

CV joints left and right make very loud clicking noise, the service department at the dealer ordered the parts in December of 2025, i have been at the dealer twice and today February 6, they told me that the parts are not expected until the end of March, I do not feel safe driving the car. Also the auto emergency brake does not work properly when backing up, false positive hard brakes happen all the time.

Backup Camera Failure (Occurred at approx. 1,000 miles) Part was on backorder, the rearview camera remained inoperative for approximately 99 days (February 22 through May 31, 2025). This rendered the vehicle non-compliant with federal rearview camera safety requirements. Emergency Braking System Issues (Ongoing) Compounding this, the vehicle’s emergency braking system would activate erratically and without cause, including: •When entering or exiting my driveway •During normal lane changes •When driving near trucks or concrete barriers Because these events occurred repeatedly and unexpectedly, I was forced to disable this safety system to avoid sudden braking events, further compromising vehicle safety. Broken CV Axles (Officially diagnosed at approx. 6,000-7,000 miles) •On May 31, 2025, the vehicle was returned to the dealership for backup camera installation and to revisit the knocking noise, this time properly documented. •That same day, both the left and right CV axles were diagnosed as broken, and I was told the vehicle was not safe to drive. •I had unknowingly been driving in this unsafe condition for almost three months. •The vehicle remained in the dealership’s possession until June 5, 2025 (6 days), Recurrence of Knocking Noise and Third Service Visit (January 10, 2026 – Approx. 15,000 miles) At approximately 15,000 to 16,000 miles, the knocking noise had returned (in both directions of steering) and I brought the vehicle in to be diagnosed •The dealership acknowledged hearing the noise. •I was told the sound is a “well-documented issue” with this model and considered “normal.” •I was informed that the vehicle was safe to drive. •I was told Honda is working on a redesigned part and that a recall is expected in approximately six months to one year. •I was specifically told Honda will not authorize replacement of the same axle parts again, as they continue to fail, and that I must wait for a recall remedy.

The automatic emergency barking system suddenly applies even when there are no obstructions. Happens regularly. I was almost rear-ended at a stop light by another vehicle because of the sudden application of the emergency braking system, even though there was nothing in front of me. Axel makes a loud cranking sound when making a right or let turn. Battery 'Service vehicle now' warning consistently comes on with warning to reduce acceleration even when the vehicle is not in motion.
