2025 Honda Prologue

I was traveling at a steady speed of 35 MPH approaching an intersection with a red traffic signal. There was a single vehicle already stopped at the light, but it was positioned a significant distance ahead of my vehicle. Without any warning, driver input, or hazard present, my vehicle initiated an uncommanded emergency braking maneuver. The vehicle forcefully decelerated from 35 MPH to a complete stop (0 MPH) in the middle of the roadway. Prior to this incident, the vehicle's forward collision system has exhibited false positive detections, frequently issuing warnings for phantom vehicles or obstacles when the road ahead was completely clear

Happens frequently. While it has not yet caused the vehicle to fully slam on the brakes, it will occasionally flash the brake warning and apply the brakes even when there are no obstacles present. Additionally, when backing out of the driveway, the vehicle sometimes detects the road surface as an obstruction and abruptly applies the brakes. This occurs consistently in the same location, likely due to the steep angle of the driveway.

While driving with cruise control engaged, the car had a false positive for forward collision detection and slammed on the brakes at full Highway speed. After about one of second of emergency braking the car released the brakes and resumed cruise control as normal. There were NO other vehicles on the road in front or to the side of us at the time. Due to the unexpected braking, the vehicle following us almost collided into us. The event triggered just before the shadow of the bridge was on road of the underpass. I suspect it was the shadow that might have contributed to this event. However, this is not the first time the vehicle has had false positives in the forward collision detection system. We have experienced many of these, but typically at lower speeds. Generally speaking the “triple beep” and associated Heads Us Display red “brake” symbols briefly flash, then goes away without engaging the brakes automatically, again with these there are no other vehicles present. We have called two different dealers to report this and they tell us there is no associated TSB/service bulletin or recall for our vehicle and no software update for this. We tell them that GM has had several software updates for their Ultium platform with their other vehicles to fix this, but there is still nothing from Honda. There is a SB 25-051 for the 2024 prologues that would seem to address this but it’s not applicable to the 2025 according to them even though the symptoms are the same. This needs to be looked into as BOTH dealers told us that they had several other customers complaining about the same thing.

We are experiencing 2 problems. The primary issue is both front axle. CV joints are clicking and making poppy noises when you turn either right or left. secondary issue, the car is having is the. Reverse collision warning problem. It is engaging and breaking the vehicle. When there is nothing behind it, it happens constantly. And we've had to turn the feature off on the vehicle's information head unit settings to stop it from causing harsh breaking. When backing up.

Car started making knocking noise at 3k miles coming from axle. I reported to Dealership. Car sways on highways when steering straight. Car stop s at 10mph when turning corners saying that a pedestrian is infront of vehicle when there is no one. Backup camera glitches. Vehicle very unsafe. Dealership not doing anything. Contacted employees that sold me the vehicle and they are acting non chalant.
