2025 Honda Civic Hybrid Complaint Log

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.

2025 honda civic hybrid just over 3000 miles has developed a ticking noise when I turn the steering. Took it to the dealership was told it was normal. If this is normal for Honda they just lost a future customer

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).

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 the dealership and declared the rattling ‘normal,’ refusing further action. The service manager promised an engineer would investigate, but that never happened. There were no warning lamps or messages prior, just the sudden onset of the subwoofer speakers on the rear deck rattling on [XXX] with no earlier symptoms. It’s been consistent since, worsening the audio with every use. The dealership’s confirmation of a widespread issue, paired with the manufacturer’s dismissal, points to a design and quality control flaw they won’t address. This isn’t a one-off; it’s a systemic problem ruining a core feature that’s been happening for a decade now with the top tier trims of Honda civics. I request an investigation into Honda on why it hasn’t rectified this issue when Honda promotes “premium sound”.
