2024 Honda Prologue

I activate the right turn signal then turn right. When the turn is complete and the steering wheel straightens out, the right turn signal is automatically cancelled (as is normal). However, one out of about five times, after the right turn signal is automatically cancelled, the *left* turn signal activates for three blinks, as though it was momentarily pressed. The dealer was able to duplicate the problem, then "test drove another Prologue in stock, duplicated concern on known good Prologue." Then the dealer went on to conclude, "Characteristic of vehicle, no problem found." The service manager and the general manager at the dealer state that this is not a safety issue. I had let the dealer know, and it is in writing on the repair order, that a car coming in the opposite direction to me turned left in front of me thinking I was turning left (because my car's left blinker was on after I had just completed a right hand turn). I braked to avoid hitting this other car. I contacted American Honda and created a case number. A few days later the American Honda agent confirmed exactly what the dealer stated. First, that Honda does not consider this a safety issue and second, that it is characteristic of the vehicle and therefore no problem exists.

While sitting idle at a traffic light, my forward collision notification beeped in spite of my Honda Prologue and the vehicle in front of me being completely still. Otherwise, no movement was taking place in front of my car. I captured this on camera during an incident when this occurred briefly. I would be happy for Honda to inspect this. I haven’t reported this to anyone else at this point. No other warning lights or messages indicated this could be a problem. This failure of my forward collision warning system has occurred about 50 times since purchasing this Prologue in late December of last year (over about 7,500 miles). At times, the beeping won’t stop unless I put the car in park. I learned the locations of the sensors behind the rear-view mirror and on the bumper. I cleaned the outer surfaces off to no effect.

I turned my car on and it made an extremely loud, dangerously loud, loudest noise you have ever heard loud, static noise. I turned it off and waited and turned it back on and same thing. I tried shifting it to drive, and the noise stopped. However, every time I did anything where the vehicle would make a noise, it would make a full-volume static blasting noise instead. It was not safe to drive and I am afraid it has permanently damaged my eardrums. This is a known issue (see links below) and needs to be fixed immediately.

Back up Camera -- Honda Prologue Elite model does not have night vision back up camera. In the night when you reverse your car nothing is visible unless you press breaks. I realized this when I got loaner car and lower model has full visibility in the dark but my Elite back up camera does not have night vision. I complaint this issue with Honda Repair center and they asked me to complaint to Honda manufacturer as all Elite has same problem. I called many time to Honda but not response. Sensor - hands-free access does not work every time. it works only randomly. I complaint this to the repair center and they said all the car has the same issue so we cannot do anything about this. As my car is on lease, they are not cancelling my lease or replacing my car.

I was driving through a parking lot when I received the following warning messages “Brake System Failure,” “Service Stabilitrac,” “auto hold unavailable,” “ Brake assist failure. Press hard to brake. Speed limited.” I then tried to pull over in the parking lot and vehicle was extremely difficult to stop. I had to use both legs on the brake. While sitting waiting on a tow truck, I received another warning message that stated “Service High Voltage System.”
