Electrical System Problems of Honda Ridgeline - part 1

When stopping with the auto idle stop system engaged, the vehicle failed to auto restart after letting off the brake pedal. This has happened three times with the last two occurrence less than a week apart. The first two times I was in a queue at a stop light and was able to shift into park and manually restart the car and proceed on the road without further incident. The third time in particular I observed that the manual start did not work on the first attempt but did on the second attempt. There were no warning indicators or messages prior to the auto restart failure. There is some risk of safety when a vehicle remains unexpectedly stopped in the road while surrounding traffic is moving. I plan to take the vehicle to the dealer for evaluation.

My wife and I had decided to empty our storage unit, so on memorial day we began moving everything into the garage. After five or six trips Honda, I pulled the car up beside the RV and close to the house for what turned out to be the last load. I unloaded my bicycle and nearly everything else, leaving only a few small items, and then removed the massage table from the back seat. The engine was off this entire time. That was when I noticed smoke coming from the engine compartment. At first, I thought the radiator had overheated, so I tried to open the hood, but it was too hot. I went into the garage for gloves and a fire extinguisher and tried again, but still could not get it open. Realizing the situation was getting worse and that I could not stop it there, I jumped into the car and tried to start it. To my surprise, it started immediately, and I drove it as fast as I could out to the street in front of the house. Only later did I realize that this likely saved my RV—and possibly the front of my house as well—from catching fire. We were so blessed that I was able to move the car to a safer location and no one was hurt. It was a miracle.

While stopped in heavy traffic at a traffic signal, the engine stopped and would not restart. This was due to the ais system. The car became disabled in heavy traffic.

The auto high beam is widely known to be so bad it behaves the opposite of how it should. It frequently blinds other drivers when it should not turn high beams on, often blinding them in the last few seconds before passing, causing a dangerous situation, not to mention the possibility of drivers thinking it was done on purpose maliciously. This has led to near road rage experiences. The high beams also rarely turn on when they should but at least there is a manual override.

The vehicle’s engine and powertrain management system repeatedly fails with multiple dtc's triggering a full-system cascade of safety-critical warnings and automatic power-limiting. The issue affects the engine, transmission, emissions, awd, brake system, stability assist, steering assist, abs/vsa, hill-start assist. The vehicle is fully available for inspection upon request. During each failure, the vehicle abruptly enters reduced-power “limp mode” without warning—resulting in loss of engine power, disabled awd, and disables all safety/stability systems. These events have occurred in normal traffic, including at red lights and in intersections, creating a risk of rear-end collisions, inability to accelerate, and loss of vehicle control.
