| Service Brakes problems |
I was driving on the street about 15 miles per hour when the car sensor sensed something in front of my car and stopped automatically when there was nothing in front of me. Almost caused a rear-end accident, luckily, the car behind was able to stop.
What happened? while driving my 2025 Honda Odyssey, the engine failed to restart during an auto idle stop event at a 4-way stop/intersection. When releasing the brake to take my right-of-way, the engine stalled completely. The vehicle became immobilized, the power steering went heavy/stiff, and the brake pedal became difficult to depress. I had to manually cycle the ignition by shifting to "park" and pressing the "start" button multiple times to regain power while traffic was waiting. This has occurred twice. What component or system failed or malfunctioned? the auto idle stop (ais) system and the starter/charging system. A service technician recently documented a "slow crank" during routine maintenance, suggesting the battery is unable to handle the restart load. How was your safety or the safety of others put at risk? the vehicle stalled during a right-of-way transition (green light/4-way stop). This created an immediate risk. The loss of power steering and the stiffened brake pedal could have made the vehicle nearly impossible to maneuver manually on an incline during the failure. Has the problem been reproduced or confirmed? a dealership technician confirmed a "slow crank" symptom during a multi-point inspection, though they could not reproduce an issue. The battery tested good. Were there any warning lamps or symptoms before failure? yes. A "slow crank" was noted by a technician when attempting to start my vehicle to check my vehicle mileage. During the stall itself, a red exclamation point warning appeared on the dashboard.
The vehicle experiences abnormal vibration and shaking felt from the rear during braking at moderate to highway speeds. The condition does not occur during steady driving and is isolated to braking events. An authorized dealership inspected the vehicle and documented rear brake rotor thickness variation but no repair was performed. The issue has continued and raises concerns about braking stability and safety, especially at higher speeds.
I came to a stop at a stop sign. Then "auto off" shut off the engine. Next, the vehicle went into park. A message came on screen telling me to press the brake and the start button. Doing so had no effect. Cars behind me started honking. After repeatedly stabbing the start button and opening and closing my driver's door, the vehicle eventually rebooted, and the engine started as normal. This caused a dangerous situation where other cars went into opposing traffic to get around me.
Normal speed of 25mph on a clear warm day with no road obstructions when the brake system indicator (red) illuminated. I pressed on the brake and had severe resistance and was barely able to stop the car. Two more indicators illuminated. One I believe was the vehicle stability assist and the other I don't recall. The screen flashed "call your dealer". The owners manual states "have your vehicle repaired immediately. " the vehicle was hauled to southeast Honda. Codes uo416-680416-f8, u0418-68, u3000-49i. The brake booster was replaced. I am concerned that an in-experienced driver traveling at interstate speeds might have a fatal issue.
While driving approximately 40 mph, the vehicles emergency avoidance system activated and applied the brakes very heavily. We were nearly hit by a vehicle behind us, which nearly caused multiple accidents. There was nothing in front of us, and the road was CO. Pletely clear in front of us.
