What 377 owners told NHTSA about the 2015 Honda Civic Sedan Si

I am having problems with my 2015 honda civic lx , my transmission failed when my wife and grandkids were getting off freeway and car stalled. This is a serious problem that Honda needs to address for consumer safety. The cvt transmissions in these vehicles are of poor quality.

The contact owned a 2015 Honda Civic. The contact stated that as her son was merging onto a highway at 25 MPH, an SUV sideswiped the vehicle which sent the vehicle into a tailspin. As the vehicle continued to spin, her son lost all control of the vehicle as the rear bumper hit a cement barrier. The airbags did not deploy upon impact. Her son was cut out of the vehicle to the accident; however, he did not sustain any injuries or need medical attention. A police report was filed at the scene. The vehicle was destroyed due to the accident and was towed to an independent tow yard. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle was a total loss. The failure mileage was approximately 130,000

While driving the check transmission light came on and vehicle would not accelerate above 20 mph. Vehicle made loud whining noise when pushing the gas pedal. Mechanic found that there was transmission fluid leaking heavily around the transmission fluid pressure switch. It is currently sill in the shop waiting for the replacement switch. Waiting to se if there are any other issues. I have seen many complaints on forums concerning the transmissions in these cars. Where is the recall?

My 2015 Honda Civic LX (automatic) began feeling like it was dragging/hesitating under 40m/h while decelerating. This would also happen while decelerating and then (without braking) accelerating (stop and go traffic or at signal). One time my car started shaking (think going on your brake and gas and brake and gas) that motion but way faster. it seems the fill cap/dipstick keeps popping out every 1000 miles and i have to manually put it back in.

Transmission fill plug popped out. From blogs I read about the car it is a common thing for the plug to pop out if the vent is clogged or from high pressure build up in transmission.

The transmission fill plug popped out and was laying right next to the fill hole on the engine. Transmission fluid leeked from the engine and has damaged/compromised the transmission.

1.8l engine Fill plug on auto transmission is blowing out! Cause: something to do with and engineering mistake on Honda's side. I'm not sure what is causing this which quickly leads to transmission failure to shortly follow the trans fill plugs blowing back out. From my research everyone on the internet is all saying the same thing is happening to their cars! This car was bought recently from a dealership with 40681 miles.

It took 4 tries before my car would start. I went to auto zone to have the battery & alternator & starter tested. Battery was dead so I had it replaced. A week later, it took 4 tries before my car would start. I took it to auto zone for testing again. Alternator was bad so I got it replaced. A week later it took 3 tries before my car would start. I went to auto zone for testing again. Alternator was bad so I had a shop replace it again. A couple days later my car wouldn't start. I was stranded & needed to get to work. The mechanic that replaced the alternators for me came to my rescue. He tested & looked up the problem. He thought the sensor on the black terminal of the battery was bad. I ordered 1 & got it replaced. My car wouldn't start the next day after work & I was stranded again. The mechanic told me to unplug the black sensor so that my car would start & I could get home safely. The next day I took it to the shop & more tests were run. Finally he told me that I need to go to a dealership & tell them I need a TSB firmware update & that there was nothing he could do for me. Honda needs to be held accountable for this.

The CVT belt broke on my 2015 Honda Civic. I see on that there was a recall for other 2015 Honda civics with the same issue. There are countless forums online with other people like me who have 2015 civics that were not covered under the CVT recall. It’s my understanding that there have been at least 40 other complaints from the thousands of other civic owners like myself who were not covered yet experiencing the same issue. Hopefully my report is enough to tip the scales. I am now being quoted $7,200 to fix a problem that has been shown to be unsafe in other civics of the same year. Thank you.

Transmission keeps popping out my fill plug and transmission fluid squirts out I’ve read online that these transmissions eventually mess themselves up

When I cold start my car it’s making this horrible metal cutting blade kind of sound sometimes, That goes away 5 seconds after cold starting the problem is the vtc actuator, many dealers took a look to not only mine but also my friends 2014 civic si, they said it was the vtc actuator and that they nor anyone else will fix the issue. This has also happened to handfuls of others.

on 10/4 i was driving my 2015 honda civic se . It began to drive as though i had a flat tire. i got out to check and i did not have a flat tire. So i continued to drive to try and get my car out of the road. It began shaking/vibrating really bad. And then the car engine turned off. SO i cut my car back on and went to put it in drive and it would no longer go into gear. It just completely stopped working. i did not have any dash board lights/warning lights come on. I have not had any issues with my car regarding transmission up until 10/4/2021. I have also seen where there is a recall on Honda's with this issue. But my VIN was not on the recall list. It seems there have been several complaints regarding this issue. And several other VIN numbers were not listed. This is QUOTE anywhere from $5800 - $7000 fix from what I've been told. There seems to be an ongoing issue with the Transmissions for this Year/Model car. Who has that kind of money to fork and pay. It seems there should be more research into this and figure out what is going on. Is there anything I can do regarding this issue???

My 2015 Honda Civic has 69070 miles on it. My car will straight out just stop in the middle of the road. The breaks and gas will stop engaging. This has been happening since late March of 2021, and continues to happen at least once a week.There’s still power as the outside lights, radio, dash lights are all still on and functioning. I took the car to a Honda dealership and they said it was the REC VSA modulator. So I have had to replace the REC VSA modulator. The car ran beautifully for a whole week, then it started again. I took it to another auto shop and had them diagnose the car and they changed the MAP sensor, and the main engine bay fuse. I’ve had the alternator and started checked and they’re both fine. The 9th gen honda civics have electrical and computer issues and Honda should be held responsible because they’re a safety issue. I am so afraid of what could happen I only take my car to work and home. Something needs to be done about these issues.

This is the 2nd Honda Civic Si that i bought first one was a 2013 and the one i have now is a 2015, I've researched this continuing problem and have found that many other Civic Si's are having this issue as well, when releasing clutch in first gear there's a grinding or clutch spring or clutch fly wheel noise that sounds like it's grinding or making a vibrational noise now when i first heard the issue in my 2013 i didn't put much thought into it, after hearing it more n more i took it into Honda and they told me they couldn't hear the noise so i let it go after a few years i bought a 2015 Civic Si and now this Si is making the same noise in the clutch area when releasing the clutch out of 1st gear, i don't know how in a 2 year difference that the clutch would be making the same noise, this needs to be taken care of it can't be that it's a driver error since many other drivers of this type of vehicle are also complaining of hearing this issue, i would like an investigation started on this to see if the manual transmission that's being used is faulty. I would also like to have my car checked out free of charge to see what the issue is with the transmission.

Intermittent warning light for problem with air bag. The light comes on and can stay on for a while, then it will go out and stay off for a while. I don't know if there is a problem with the air bag or with the light.

The transmission cap is a major flaw in this design (Honda Civic 2015) . As you can tell by the pictures the vehicle is clearly losing transmission fluid and possibly leaving it open to exposure of debris. There is also no dipstick so you can't tell where the fluid level is. The vehicle also does not detect or notify the driver if the cap has come off. Honda needs to address this issue and until then, transmission services should be offered at no charge to the vehicle owner by Honda. Even if you put the cap back on it will come off because of pressure build up. If you find a way to keep the cap on you might cause pressure build up somewhere else. Honda has not offered a solution to this design flaw.
