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

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

Driving about 40 mph on a rural road, coming up to a curve in the road (or already in the curve when suddenly the 2025 Honda civic hybrid sedan sport touring beeped fast and then immediately braked hard. There was no car in front of me but there was a car coming towards me in the opposite direction. There was no fog or rain, it was daytime. Believe the CMBS caused this. If a car would have been close behind me, I may have been rear ended. Also, if this happened on snow or ice, would have lost control. Did not take it to the dealer as others have stated, they could not find the problem. I believe the dash showed “ Brake” just as it happened but nothing before.

While driving down the highway, my sunroof suddenly and unexpectedly shattered without any external impact with no warning. My safety was put at risk because the glass exploded all over me and could’ve caused an accident had I been around other drivers. The dealer told me it was hard to determine if this was a defect or something hit my car and stated I need to bring it into them specifically for inspection, I haven’t done so yet expecting that this will result as my fault so I’m taking precaution before going there.

Sunroof spontaneously exploded on the highway. Was maintaining a good distance between my car and the car in front of me, so I doubt it was a rock that was kicked up that broke my sunroof. Glass looks like it broke from inside out.

The vehicle unexpectedly began accelerating from a creep with no accelerator input. Acceleration ceased immediately as soon a the brake pedal was touched. No actual braking was required--simply a touch on the pedal. Acceleration was as if the accelerator pedal had been pressed about 1/4 down. It lasted about 1.5 seconds from initiation to touching the brake pedal. The pavement was not on a grade but was substantially level. This is the 3rd or 4th such incident in the last few months. In the other incidents I was unsure if it was my imagination or some unrelated factor like grade. In previous incidents I had been about to accelerate in any case, and pressing the accelerator overtook it. In this incident, the car was navigating a parking lot, having just pulled out of the parking space and moved 50-100 ft. The car was moving in "creep" mode, i.e., the EV system simulating the creep of an automatic transmission (ca 0-4 mph). My impression is that each incident occured not long after restarting the car, though I am not fully certain of this. In this occurence there was one passenger; in all previous occurences there was no passengers. In all occurences, the Cruise Control system was on but not engaged. The "driving style" was set for Normal, as opposed to Sport or Eco. No alerts or unexpected lights were observed on the instrument panel. For the latest incident, the driver's floor mat was checked and found to be properly secured and well clear of the accelerator pedal. The car's last (and only) service was the normal Honda "A1" maintenance in May 2025 at ~11000 miles. Service was done at a Honda shop, so any firmware should be current to that date. The shop was not notified of the acceleration issue at that time. The Honda shop has been notified today (July 5).
