Honda Civic Hybrid loss of power problems

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

I drove this 2003 honda civic hybrid took my baby honestly from the shopping market. It was just at the right turning corner, the vehicle suddenly lost power to move, I immediately press the emergency button, got out off the vehicle let other autos passed me ahead by the side way. Later some kindly guys help me pushed the car to a parking lot near by. The transmission was out of work. After my friend help me took baby home, the vehiclel was towed back. Glad is not on the highway. It only just passed 100k miles. The transmission fluid was good, output speed sensor is ok. I think not only me have this quality problem. It is too dangerous for us without a sign.

My 2005 honda civic hybrid is experiencing a shudder with momentary loss of power upon acceleration from a stationary position. Vehicle has been taken to honda dealership for a clutch burnishing procedure. This temporarily fixed the problem for approximately 3000-4000 miles. Problem has returned and has become a safety concern as there is momentary loss of acceleration power during the shudder event. Dealership insists on charging for another burnishing procedure though it is outlined in a technical notice. This shuddering happens upon every acceleration from a stationary position. It is not intermittent and can be felt every time I accelerate.

It appears that there may be a trend of premature ima battery failures for this vehicle and should be investigated. On our brand new 2010 honda civic hybrid with less than 952 miles and less than 4 months of use, the ima and check engine lights came on. Ima battery - premature battery module deterioration (code p0a7f.) was determined to be the cause of ima and check engine light. The battery module was replaced by the honda dealer. Ima and check engine light came again in october 2013, less than 3 year of use. Took it to the honda dealer. They checked it out and replace the battery module on 10/31/2013. The ima code was the same, p0a7f high voltage battery deterioration. The mileage was 46,084. Two ima battery failure in less than three years appears to be excessive. The original warranty on ima battery module is 8 years, 80,000 miles (for ohio) as listed in the owner's manual . For some states, it is 15 years, 150,000 miles. Although, both batteries were replaced under original warranty, it appears that there may be a trend of premature battery failures for this vehicle and should be investigated by appropriate agencies and the car company. Safety as a result of loss of power without the battery assist, fuel consumption (mpg), replacement costs of batteries and time required for the repair/replacement are the main concerns. The warranty info on the replacement is sketchy and unwritten.

Honda applied a software patch to extend the ima battery, driving home from the appointment where they updated the software I noticed that at times when I go to accelerate the car will bog down and have no speed. It happens randomly, no set pattern, its a dangerous situation when you are on a 2 lane highway and you pulled out to pass someone and you have no power. Or you are making a left hand turn and all of a sudden you lose power. Then living in minnesota having these issues when you on ice is down right scary! When you car does decide to go you all sudden lose control because its on ice. Honda has updated the software patch again and there is some improvement but still I can't trust it to drive in rush hour situations or have younger drivers drive my car. Now when I complain to honda they tell me it drives the way its designed, well if that's the case all honda's need to be taken off the road before someone is seriously hurt. Please help us honda drivers who are stuck with this car....
