Honda Civic Hybrid check engine light comes on

Filed Oct 4, 2026 · Brakes, Driver assistance · NY

I am reporting a serious and recurring safety defect involving my 2025 Honda Civic Sport Touring Hybrid. This is the second occurrence of a serious vehicle malfunction, and the vehicle has experienced numerous other significant problems during my ownership. During the most recent incident, I was traveling approximately 45 MPH when the vehicle experienced a sudden loss of power. I was unable to accelerate, the vehicle shut off while I was in the middle of the roadway, and the vehicle subsequently went into limp mode. At the same time, the vehicle displayed multiple warning lights and safety-system warnings, which I documented in a video. The ABS system is still not functioning, and the electronic parking brake is also not functioning. Other vehicle safety/driver-assistance features are also unavailable. Before and during this incident, the check-engine light was flashing. The vehicle was also shaking severely and making extremely abnormal engine noises. The check-engine light later became solid, but the vehicle continued to have serious problems. I had the vehicle scanned and received a diagnostic report showing confirmed and permanent diagnostic trouble codes P1659 and P2108. The diagnostic report recommends replacing power relay(s). P1659 concerns the Electronic Throttle Control System (ETCS) control relay, and P2108 concerns Throttle Actuator Control Module performance. I am extremely concerned because this is not simply a check-engine-light issue. The vehicle lost power and shut off while traveling approximately 45 MPH, leaving me unable to accelerate while in traffic. The vehicle then entered limp mode, while critical safety systems, including ABS and the electronic parking brake, remained unavailable. This is the second occurrence of a serious malfunction involving this vehicle. I have also experienced several other significant problems with this vehicle during my ownership, including a substantial water leak that allowed water to enter the vehicle and ca

Was driving on the freeway when suddenly my car engine shuts off. There is still power too the car but the speed odometer doesn't work, along with whatever is used to monitor the milage I have traveled. I have to switch it too low gear in order too keep it going or the car stops even when im going 65. It has happened now multiple times and when shifted into park it won't shift out of park for several hours. I have to disconnect the battery terminals too reset the codes because if I don't ill end up sitting in my car several hours before I can start moving again. The lights that illuminate are the brake system, check engine light, and ima system all amber. If I didnt act as I did this time it would have been like the first time where I actually did stop on the freeway causing for a traffic jam, not only was that embarrassing it was also scary being stuck in the furtherest left lane with no shoulder on the left side too pull off the freeway and all the cars speeding at 65 MPH or more by me .

My son purchased this vehicle from an individual at a dealership. Drove the car home with no problems, the check engine light was on and the seller did tell him there was an issue with the ima battery, but that it didn't keep from driving it. Didn't crank the car for 2 days. When we put the 10 day tag to get inspection done it wouldn't start. Took the 12 v battery out got it tested and showed bad battery. Replaced the battery, drove around and it died the steering stopped, the lights started flickering and it wouldn't restart. We took the new battery out got it recharged but are unable to drive it more than 10 miles without it flooding power and finally leaving stranded. If it was a standard vehicle I would say it was the alternate but this car doesn't have that. The ima battery needs to be replaced and without it the car is trash. What can we do with this car? I can't sell it, that wouldn't be right. The man who sold this car to my son was wrong in doing so.
