2025 Honda Civic Hybrid problems

“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…”

“On 5/20/25 while pulling out of my house's driveway I saw a warning on my dashboard that the brakes were malfunctioning, that it was unsafe to continue driving, and to stop as soon as possible. The brakes were soft and I could feel and hear a grinding noise when I stepped on the brake. I returned the car to the driveway. The vehicle was towed the same day to the dealer for service. The car was repaired on 5/23/25. The repair invoice states: "Electric brake control internal circuit malfunction...brake hold simulator not pluging...replaced simulator set (part#:01469-T61-A02). Car was tested after repairs." (Purchased on 4/4/25.)”

“On a two way lane highway, vehicle detects on coming traffic and causes sudden deceleration of vehicle and braking which can cause being rear ended by another vehicle. This also occurs on multi lane freeways when going in the same direction the vehicle will detect a vehicle in the lane next to me braking and again cause the vehicle to decelerate and brake which could cause an accident. Occurs at least once or twice a week. I have a video of the issue which might be better”

“On [XXX], at about 3,500 miles, the subwoofer speakers in my 2025 Honda Civic Hybrid Sport Touring began rattling persistently at moderate volume (14-15), disrupting the entire audio system. The component malfunctioned, no ‘failure’ in the traditional sense, but it renders the sound distorted and unusable, far from the advertised premium sound quality on Honda’s website. It’s still in the vehicle, available for inspection if requested. This doesn’t directly risk physical safety, no crash or injury, but it severely impairs the driving experience, as the audio system is a key feature I rely on, now reduced to a constant, irritating rattle. The problem has been reproduced and confirmed on all the other vehicles of the same model and trim at the dealership where I bought it, Honda mall of Georgia in Buford, GA. I took it in for repairs twice, first on March 25, then again on April 2, and it spent 7 days in the shop total. Both times, the rattling persisted unchanged. The service team acknowledged it’s a model-wide defect affecting other Civics of this trim, yet no effective fix was applied. The manufacturer’s regional representative inspected it indirectly through…”

“I've previously reported the CMBS (Collision Mitigation Braking System) and RDMS (Road Departure Mitigation System) warning messages that have been appearing too frequently. Today is the day it finally happened, my wife was driving on the highway when auto cruise control with lane keep assist set at 66 on the passing lane, with a truck to the right. Halfway passing the truck on auto cruise control with lane keep assist, our Honda suddenly automatically braked (went from 66mph to ~56mph, there were no vehicles in front of her). She urgently took back control and sped up as the warning lights flashed (collision mitigation braking system problem - 60mph and road departure mitigation system - 58mph, pictures attached) and the driving assist features that were originally on all became disabled. All of this happened at about the same time in a manner of ~3 seconds. She was lucky that no one was behind her at that moment, and she did not get into an accident or worse! Honda has done nothing to fix this issue, and we have already taken the vehicle to the dealership's service 3 times already. Please expand the investigation to ALL Honda vehicles that uses their Driver…”
