Filed Oct 28, 2026 · Engine · OH

With no warning engine started making a loud ticking noise and within a couple of days it was a loud knocking noise. Flashing check engine light came on and engine lost power. Shut down and restarted engine, knocking noise still there but check engine light is not flashing. Knocking noise is loud and vehicle cannot be driven. Mileage is around 170000 but has had regular oil changes. Mechanic has confirmed the engine knock and said not to drive it. Can't afford to replace the engine.

Engine seized Honda dealership found a hole in block. Estimated repair almost $13k for a used motor. Contacted American Honda and after several weeks they refused assistance. I was barely able to exit freeway. I had to walk as area was remote without cell coverage. I understand there is a lawsuit for this issue and an investigation. I feel I have no choice but to pay for the repair as I care for a disabled son. However the evidence is the damaged motor so I am unsure what to do. This could have been a serious safety issue. An others with this motor need protection. Also for my family it’s like vaporizing $13k and going a month without necessary transportation. I am frankly shocked Honda is aware of this potential problem and refused to assist.

Driving home from work on a Friday about 1am and my engine started t knock and sputter and the engine light started flashing. Luckily I made it home. I let it sit for a minute and started it back up and it ran fine. I let it sit over the weekend I made an appointment the the dealership for the following Monday. On Monday it started fine to go to my dealer appointment but half way there every caution light imaginable came on and the info screen was scrolling failure of every system in the truck it seamed. Even the D for drive was flashing. It was knocking, sputtering with loss of power. Like it was in limp mode. Made it to the dealer and they said it was misfiring which caused the engine to come apart inside. 11K for a new engine or 8K for a used one with 46K miles. The truck only had 86,000 miles on it and has been always dealer maintained. We buy Hondas mostly for their reliability. Skeptical about buying another one

My 2021 Honda Ridgeline engine failed in heavy traffic on the freeway. The car malfunctioned and I lost complete power and started coasting and barely made it through 4 lanes of heavy traffic before the car coasted to a stop. Very dangerous and very lucky not to get hit changing lanes and then waiting on the freeway for assistance. I've made regular oil changes as directed by the computer on the vehicle. The problem was not connected to a lack of oil. I'm [XXX] and I take very good care of my vehicles. Not one scratch on my black edition Ridgeline. My vehicle is still at the Honda dealership. I don't believe I should pay for another engine nor do I have the money to do so. Having a complete engine failure on the freeway is a major safety issue and Honda needs to fix it now and in the future.
