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

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.

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???

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.

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.

The contact owns a 2015 Honda Civic. The contact stated that she noticed there was fluid leaking on the ground while the vehicle was parked. The vehicle was taken to an independent mechanic and diagnosed that the transmission cap had come loose and the transmission needed to be replaced. The vehicle was not repaired and remained at the dealer awaiting a transmission replacement. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was unknown.

Transmission fluid cap keeps falling off. FIrst time transmission felt sluggish and would go into high RPM just getting up to 20mph. Honday replaced the cap, and filled up the fluid. 4 months later it happened again, except this time I had no warning and when I went to move my car it would go into high RPM but barely move.

Transmission started acting up out of the blue and just popped while going down the road. No unusual driving activity or anything. Noticed there was electrical control dash all lights blinking about 3 days before incident and car stalled in road. Restarted car a couple times and lights went off and car went back to driving fine. Day of incident, i was replacing spark plugs and went out to test car. went a couple miles and filled up with gas. After leaving gas station, car was not accelerating almost at all, but then would start moving very slowly. Once up to speed of about 55 miles per hour, driving was ok. pulled of exit going home and came to stop light. turned green and went to accelerate and heard a loud pop and that was the end of driving. Car is still sitting at residence in current condition.

The car was running and was at a complete stop, when excelerating the car it sounded like you were driving over rumble strips. When I got home with car and parked I looked under car and transmission fluid was dripping excessively. I talked to a mechanic and he told me I should NOT drive the car. My car is a 2015 Civic EX with only 42000 miles.

WE WERE STOPPED AT A TRAFFIC LIGHT WAITING TO TURN LEFT; ONCE TRAFFIC CLEARED AND I STARTED DRIVING, THE CAR BEGAN TO SKIP AS THOUGH I WERE DRIVING ON A FLAT TIRE. WE WERE ABLE TO CLEAR THE INTERSECTION AND PULL INTO A PARKING LOT JUST A FEW YARDS AWAY TO CHECK TO SEE IF WE HAD A FLAT TIRE. THE TIRES BEING FINE, WE PROCEEDED TO PULL AWAY BUT THE CAR WAS STILL EXHIBITING THE SAME SYMPTOMS. BEFORE WE COULD GET PULLED INTO A PARKING SPOT, I LOST ALL POWER TO THE FRONT WHEELS NO MATTER WHAT GEAR I PUT IT IN. THERE WERE NO WARNING INDICATOR LIGHTS ON THE DASH AND THE VEHICLE HAD BEEN RUNNING PERFECTLY UNTIL I MADE THAT LEFT TURN. THERE WAS NEVER A SKIP OR JERK IN THE TRANSMISSION OR ANYTHING THAT WOULD INDICATE A PROBLEM PRIOR TO THIS MOMENT. I NOTICED THERE IS A RECALL FOR THE SAME EXACT THING HAPPENING BUT MY VIN NUMBER IS NOT ONE THAT IS COVERED. THROUGH MY RESEARCH I HAVE DISCOVERED THAT THERE IS A NHTSA CAMPAIGN FOR THIS ISSUE. CAMPAIGN NUMBER 15V574000 IS THERE CURRENTLY ANY HELP FOR THIS ISSUE?

I NOTICED THAT THE FILL PLUG ON TOP OF MY CVT HAD POPPED OUT AND I PUT IT BACK IN, ONLY TO FIND, WEEKS LATER, THAT IT HAD POPPED OUT AGAIN AT SOME POINT. THE PLUG IN THE TOP OF THE CVT IS A VERY SNUG FIT, SO FOR IT TO BE POPPING OUT, I WOULD HAVE TO ASSUME THE TRANSMISSION MUST BE UNDER QUITE A BIT OF PRESSURE. I DID SOME RESEARCH AND FOUND THAT OTHERS WITH THE SAME YEAR/MAKE/MODEL VEHICLE HAD EXPERIENCED THE SAME ISSUE. YESTERDAY 03/06/2021 I WAS TRAVELING ON THE INTERSTATE AND HAD TO SLOW DOWN TO A STOP DUE TO BACKED UP TRAFFIC, AS I BEGAN TO ACCELERATE AGAIN MY VEHICLE BEGAN VIOLENTLY VIBRATING/SHAKING. I CONTINUED TO EXPERIENCE THE VIBRATING UNTIL TODAY, 03/07/2021 WHEN MY TRANSMISSION WENT OUT AS I WAS DRIVING DOWN MY DRIVEWAY AND THE VEHICLE WOULD NO LONGER GO INTO GEAR AND WOULD NOT MOVE, PROMPTING ME TO HAVE TO PUSH IT BACK TO MY HOUSE.

AT 83450 MILES THE TRANSMISSION WENT OUT. I DRIVE EASY HIGHWAY MILES TO WORK. NO STOP AND GO TRAFFIC. I WAS STOPPED IN MY DRIVEWAY WHEN SEVERAL WARNING LIGHTS BEGAN TO FLASH ONE AFTER THE OTHER. I REMEMBER THE UPHILL ASSIST LIGHT, POWER STEERING LIGHT, AND 2 OTHERS CAME ON. THE CAR IS NOW NOT UNDER WARRANTY.

I DRIVE A 2015 HONDA CIVIC AND I WAS AT A STOP SIGN AND STARTED DRIVING, GOT TO ABOUT 15 MPH AND IT FELT LIKE I GOT A FLAT SO I STARTED TO PULL OVER AND REALIZED I DIDN'T HAVE ANY POWER TO MY FRONT WHEELS NO MATTER WHAT GEAR I PUT IT IN. THERE WAS NO WARNING SUCH AS JERKY TRANSMISSION OR ANYTHING THAT WOULD LEAD ME TO BELIEVE THERE IS A PROBLEM AND NO LIGHTS ON THE DASH COME ON SAYING THERE IS A PROBLEM SO I'M NOT SURE WHAT TO DO. I NOTICED THERE IS A CURRENT RECALL FOR THE SAME YEAR/MAKE/MODEL AND THE SAME EXACT THING HAPPENING BUT MY VIN NUMBER IS NOT ONE THAT IS COVERED. NHTSA CAMPAIGN NUMBER: 15V574000 AND I'M PRETTY SURE MY DRIVE PULLEY SHAFT IS BROKEN.

MY TRANSMISSION WENT OUT WITHOUT ANY WARNINGS. AFTER DOING SOME RESEARCH THERE WAS A RECALL THAT WAS ISSUED BUT MY CAR WASN'T INCLUDED BECAUSE IT WAS ONLY FOR THE 2015 MODELS MANUFACTURED BEFORE NOVEMBER 2014. BUT IT WAS THE SAME SYMPTOMS I LOST ACCELERATION AND THE FRONT WHEELS LOCK UP WHILE DRIVING. I ONLY HAD LITTLE BIT OVER 90000 MILES ON THE CAR. I DID REACH OUT TO HONDA BUT ALL THEY TOLD ME WAS I WAS OUT OF WARRANTY AND MY CAR WASN'T INCLUDED IN THE RECALL AND I NEED TO TAKE IT TO THE DEALERSHIP AND EVEN IT'S THE SAME ISSUE AS RECALL THEY COULD NOT PROMISE ME THEY WOULD GET IT FIXED FOR ME. I DO NOT EXPECT TO BE REIMBURSED FOR THE TRANSMISSION REPLACEMENT BUT I WANT THIS TO BE LOOKED INTO SO OTHER PEOPLE WON'T HAVE TO GO THROUGH THE SAME THING AS I DID. I WAS STUCK ON HIGHWAY IN THE MIDDLE OF NIGHT AND HAD TO GET MY CAR TOWED. PLEASE INVESTIGATE THIS CASE. I WAS ON I-77 (CHARLOTTE NC)DRIVING HOME AND THE CAR STOPPED I WAS FORTUNATE ENOUGH TO PULL OVER TO THE SIDE WITHOUT GETTING HIT BY ANOTHER CAR. I BARELY MADE IT. AND FOR HONDA, NOT EVERYONE CAN AFFORD TO PAY TO GO TO THE DEALERS TO GET THEIR CAR LOOKED AT. I'M UPLOADING THE ESTIMATE BUT THE COST IS LITTLE BIT HIGHER DUE TO ADDING 2 YEAR WARRANTY. IT CAME OUT TO BE AROUND $2800.

NOTICED THE CVT TRANSMISSION FILL PLUG LAYING ON TOP OF THE TRANSMISSION. PUT THE CVT FILL PLUG BACK IN AND DROVE 30 MIN TO DESTINATION. PARKED AT DESTINATION AND CHECKED FILL PLUG TO SEE IT LAYING ON TOP OF THE TRANSMISSION AGAIN. I SUSPECT THE CVT TRANSMISSION IS BUILDING PRESSURE AND BLOWING THE FILL PLUG OUT, ALLOWING CONTAMINANTS TO ENTER THE TRANSMISSION AND RUIN IT.

CAR STOPPED PROPELLING FORWARD AS IF TRANSMISSION SUDDENLY WENT OUT WHILE I WAS DRIVING ON INTERSTATE 29 JUST BEFORE THE ON RAMP TO INTERSTATE 80 AT STEADY SPEED (NOT SPEEDING, NOT ACCELERATING...JUST WENT OUT AS I WAS DRIVING). NO CLUNKS, JOLTS, LOUD NOISES...THE ABILITY TO ACCELERATE WAS JUST GONE. COASTED TO THE SIDE OF THE ROAD. NO GEARS WOULD ENGAGE WHEN I TRIED TO PUT IT IN GEAR. THE HANDLE MOVED, BUT ENGAGED WITH NOTHING. TRANSMISSION FLUID HAD BEEN CHANGED IN JUNE 2020. THIS HAPPENED ON SEPT 28, 2020. LIGHT NOISE AT PARKING LOT BEFORE THAT ON ACCELERATION. I STOPPED AND LOOKED AT IT, BUT NOTHING OBVIOUS. IT WAS DANGEROUS IN THAT THERE WAS NOTHING I COULD DO EXCEPT COAST OFF TO THE SIDE OF THE ROAD. THERE WAS CONSTRUCTION THERE, BUT FORTUNATELY I COULD PULL OVER BEFORE THE ACTUAL ON RAMP, BUT THAT PARTICULAR CURVE IS DANGEROUS BECAUSE IT'S VERY BUSY WHERE TWO INTERSTATES CROSS SO I WAS STALLED IN A BAD PLACE. DON'T KNOW THE PARTS OR INVOICES YET. (THIS BOX IS SO SMALL I CAN'T SEE THE WHOLE PARAGRAPH. I CAN ONLY SEE TWO LINES AT A TIME.)
