2025 Honda Ridgeline electrical system problems

“On XXX, while driving my HondaTrue Certified 2025 Honda Ridgeline RTL AWD, I stopped at a traffic light and the Auto Idle Stop system automatically shut off the engine. When the traffic light turned green and I released the brake pedal, the vehicle attempted to restart but failed. The starter sounded weak, as though the battery did not have sufficient power to crank the engine properly. The transmission automatically shifted into Neutral, and a battery warning light illuminated on the dashboard. I was unable to accelerate or move the vehicle under its own power. I had to shift the transmission into Park, press the ignition button to shut off the vehicle, and then manually restart the engine. The engine restarted normally, and the battery warning disappeared. I contacted an authorized Honda dealership, Lia Honda of [XXX], on XXX. After checking my vehicle's VIN, the service advisor informed me that a Honda service bulletin issued XXX, applies to my vehicle. According to the advisor, Honda currently recommends disabling Auto Idle Stop until a permanent repair is available. This malfunction occurred in active traffic and created a safety concern because the…”

“When driving the vehicle and you come to a stop, the auto start-stop system will shut the engine off but fail to restart the engine when the foot is removed from brake. Warning lights come on, and you have to put the car in park and repeatedly press the brake and start button. Because I am blocking traffic and trying to restart the vehicle, I cannot get photos of the warning lights. After 30-60 seconds, the vehicle will restart and drive normally. But during that time, you are blocking traffic and cannot move the vehicle. This has happened approximately 10x to me in the 22 months that I have owned the vehicle- 3 times in the past week alone. The problem first started when the vehicle was approximately one year old with approximately 20k miles. Dealer says there is a recall or warranty extension on vehicles with the same engine (Honda Pilot) but not on the Ridgleline. The Honda dealer has confirmed the problem and recommended a new starter and batteryff at a cost of over $1,500. But the car starts normally most of the time, so there must be something that causes it to fail to start at only certain times.”

“I've been having trouble with the auto start stop on my vehicle pretty much since i bought it. If I don't forget to disable it, when i come to a stop light my truck won't restart and shut off. Leaving me scrambling to restart it while i have cars flying by me. I've taken it to the dealership multiple time. They've changed the throttle body when it was under warranty, that didnt fix it. they've changed the battery, that didn't fix it. Also when it happens a bunch of warning lights come on for power steering, lane assist, hill decent braking etc.. Then when i turn the vehicle off they all disappear. I've done research on this and its a known problem with other honda years and models. Why this hasn't been recalled and fixed I have no idea, but I am genuinely afraid for my and my childrens safety.”

“This vehicle has auto stop for fuel economy. It can only be turned off each and every time you start the car. I often turn it off but do forget to do so sometimes until it occurs on my trip. The problem is that approximately 7 to 10 times, when the feature is left on and the truck shuts itself off at a stop light, when attempting to go, the truck does not restart, a warning light comes on and instructs you to put it in park. You must put it in park, then shut off the truck, then restart in order to proceed. This is extremely dangerous and very unnerving when it occurs. I travel daily on a 55 mpg road with multiple lights. The problem could easily result in being rear ended as you try to go through the procedure to get going again once the light turns green. At the very least, I get angry beeps trying to get me to move which only heightens the anxiety. I contacted the Honda dealership. They acknowledged it was a problem but that no recall has been mandated thus far and there is nothing they could do. They only suggested to call corporate Honda.”

“The starter on my 2025 Honda Ridgeline is bad. I got stranded at an intersection with my kids multiple times. I've done research and found this is a noted problem with the start stop feature especially hot starts. There are so many problems I've read that the starters are back ordered 7-10 wks. Please look into this more and issue a recall.”

“Auto start stop system. Shuts off engine at stop lights, will fail to re-start engine when I release the brake and step on the gas. Has happened several times. Came close to being rear ended. Dealer service manager told me to dit the disable switch every time I start the vehicle.”
