What 220 owners told NHTSA about the 2020 Honda Civic Si

I reported this issue to insurance. The facts are that when I was watching a family member’s toddler, I went to my vehicle to grab a stack of papers. While holding her, I reached in and grabbed the papers sitting directly on the back seat of the coupe vehicle (I.e., easy to reach). Upon grabbing the papers in one hand and holding her on my left hip, I shut the drivers side door and began walking toward the home. Immediately, I heard an odd sound like a rustle or possibly an animal scurrying. I looked around confused because I hadn’t seen anything and it wasn’t too dark. Then I looked closer and the entirety of my back windshield was shattered into a billion pieces leaking into my back seats and onto the car seat placed there for when I frequently pick up the toddler. I can’t help but think of what would’ve happened if she was in her car seat and the glass shards (which were many, sharp and permeating through each crevice and likely will remain until somehow discovered or hurting someone) would’ve fell there. Many honda owners experienced this issue of combustion in the rear windshield. It’s not safe or right. A recall should be made.

The vehicle has experienced a complete failure of the A/C condenser unit due to refrigerant leaks originating from manufacturing defects in the tube walls. This matches the exact physical failure described in Honda Service Bulletin TSB #19-091. However, the manufacturer is refusing coverage because this specific VIN falls just outside their current arbitrary cutoff list. This component failure directly impacts vehicle safety by disabling the vehicle's capability to dehumidify the cabin and clear a heavily fogged windshield during sudden humidity or temperature changes, causing an immediate visibility hazard.

My infotainment center has repeatedly failed during operation. It is distorted while driving, freezes, stuck on previous screen display. This causes all safety features to be inoperable. I can’t see the camera back up display. I can’t see the map or upcoming exit/next direction. The Honda genius features are impacted by this. My vehicle suddenly thinks I am exiting while I’m driving and randomly slams on breaks with no vehicle or object in front of me, it jerks my wheel even though there is no car or barrier next to me. I have resorted to turn off all of the safety features due to the infotainment center glitches making my vehicle very unsafe to operate. I have been in several near miss single vehicle accidents. Picture added to show screen distortion and no direction listed. Should be displaying navigation and upcoming turn but is frozen and distorted.

I was driving down the road and all of a sudden I heard a large explosion and pulled back the moonroof visor a little and could see the glass was all spiderwebbed and closed it again, I was about 3 miles from home and had my 80+ mother in the car so I got home before looking at the damage and found a huge blow out of my Moonroof glass. Not sure if it was a stone or something that hit it or if it just blew out spontaneously, was a frightening situation.

THIS 2020 HONDA CIVIC SI HAS BEEN NOTHING BUT TROUBLE. FROM THE START I HAD THE WINDSHIELD CRACK ON ME FROM WHAT HONDA SAID WAS A TINY CHIP. I WENT IN TO WORK WITH MY WINDSHIELD SEEMINGLY FINE ONLY TO COME OUT TO A SPIDER WEB SPLIT ALL THE WAY ACROSS THE WINDSHIELD. HONDA WOULD NOT COVER CITING IT TO BE JUST AN 'ACCIDENT' AND I WOULD HAVE TO GET IT FIXED. THE WINDSHIELD ABSOLUTELY HAD TO BE REPLACED WITH FACTORY OEM GLASS DUE TO SAFETY FEATURES WHICH WAS ON BACK ORDER SO I WAS FORCED TO DRIVE AROUND WITH A BROKEN WINDSHIELD FOR CLOSE TO 2 MONTHS. COMPANY THAT INSTALLED GLASS SAID THIS IS BECOMING MORE 'NORMAL' SO TO SAY AS THE GLASS THEY ARE USING IS PAPER THIN IN HIS WORDS. ON TOP OF THAT FROM DAY ONE OF OWNING THE CAR IT HAS THE 'SAFETY' FEATURE OF LANE KEEP ASSIST AND THIS FEATURE WILL LITERALLY PICK UP HEAVY SHADOWS ON THE ROAD FROM POWER LINES AND TRY TO CORRECT YOU AS IF YOU ARE DRIVING OUT OF A LANE! COUNTLESS TIMES I HAVE HAD TO HURRY AND OVER RIDE THE ASSISTANCE JUST TO KEEP IT FROM MAKING ME RUN OFF THE ROAD! HONDA SEVERELY NEEDS TO LOOK INTO THIS ON TOP OF THEIR UNSAFE THIN WINDSHIELDS WHICH CRACK FROM THE TINIEST OF PEBBLES HITTING THEM. ALSO, I JUST HAD TO REPLACE THE CLUTCH AND COMPONENTS IN THIS VEHICLE AFTER JUST 20K MILES AND LESS THAN A YEAR OF OWNING THE VEHICLE. HONDA OFFERED NOTHING BUT A ONE TIME GOOD WILL ASSIST IN PAYING FOR PARTIAL LABOR AND PARTS. THIS STARTED HAPPENING AFTER A NORMAL DRIVE TO WORK ONE DAY WHILE GOING UP A HILL THE CLUTCH STARTED SLIPPING. MADE AN APPOINTMENT AND TOOK THE CAR IN AND WAS TOLD TO PUT ANOTHER 100 MILES ON THE CAR AND BRING BACK TO THEM ALTHOUGH THEY SAID THEY FOUND A TRANSMISSION LEAK AND NEEDED TO FIND THE SOURCE . THIS WAS CERTAINLY VERY UNSAFE AS WHILE DOING THOSE 100 MILES THE CLUTCH COMPLETELY BURNT OUT AND I WAS LEFT STRANDED ON THE SIDE OF THE HIGHWAY AND I WAS PUT IN A DANGEROUS SITUATION.

ON 24 FEB 2021, WHILE DRIVING DOWN A STATE ROAD AT ABOUT 50 MPH, MY MOONROOF SUDDENLY EXPLODED OUTWARD. THE MOONROOF WAS CLOSED AT THE TIME OF THE EXPLOSION. I HAD NOT PASSED UNDER ANY OVERPASS (DROPPED OBJECT), NOR WAS I PASSING OR HAD I BEEN PASSED BY ANOTHER VEHICLE (THROWN DEBRIS). THE VEHICLE IN FRONT OF ME WAS OVER 200 YARDS AWAY. WHEN THE MOONROOF UNEXPLAINABLY EXPLODED, MOONROOF GLASS WAS THROWN ACROSS MY ROOF AND TRUNK, SCRATCHING THE PAINT. THE REPAIR BILL FROM MY LOCAL DEALERSHIP FOR JUST THE MOONROOF REPAIR WAS $976.66. I FEEL THERE CAN BE NO OTHER EXPLANATION TO THE EXPLODED MOONROOF OTHER THAN SOME TYPE OF DEFECT WITH THE CAR. THE GLASS EXPLODED OUTWARD, AND THE ENTIRE GLASS WAS SHATTERED. IT WAS NOT A "ROCK CHIP" OR OTHER TYPE OF DAMAGE SINCE NOTHING ELSE WAS IN THE AREA.
