2020 Honda Civic Power Train

This model Civic Si was build by Honda with a defective clutch. Mine began to fail at less than 60K miles. It started in the higher RPM 5K to 6K in the taller overdrive gears. This clutch design was unable to support the torque of the motor, which led to its premature failure. It's well documented in Honda forums that the clutch is weak and prone to early failure. It usually starts to fail in the upper gears under moderate acceleration. Once it starts to fail it does become a problem. Honda appears to be aware of the problem as they did have a TSB out that allowed for replacement for 5 years of 60K miles. However, reports on the internet seem to state Honda charges $2K just to tear down the car to look at the clutch. My car was low mileage and still hasn't hit 60K miles but outside the 5 year warranty. However, even if Honda had agreed to replace the clutch they reportedly leave the original dual mass flywheel, which would contribute to a shorter life span for the new clutch they just installed. The OEM manufacturer Exedy won't sell you the same clutch that Honda put into this car, and will only sell you the clutch from the type R. Thus it does appear clear that both Exedy and Honda were fully aware of the manufacturer defective clutch. A clutch like this should last over 100K miles. However, Honda rather then recalling them appears to have just thrown it to the wind and is willing to just let whatever happens pan out and see what's left . The failure of this clutch once it starts to slip does appear to be a relatively short process before total failure. Although it appears there has been no deaths so far there is a good chance someone will delay replacing that clutch because of cost, which could lead to a severe auto-accident or death. Even if Honda doesn't want to do a recall or reimburse their car owners they should at least issue an alert to owners about their defective clutch with free inspections. Respectfully submitted.

Clutch started slipping all of a sudden. Check to see if it was under warranty said the warranty had expired because the car was over 36,000 MI did not know about the extended clutch warranty at the time that Honda was extending it due to defective parts so we replaced it ourselves. Upon tear down it was discovered that the clutch disc was only about 30% worn down there were no hot spots in the flywheel or the clutch cover so the problem was related to the holding force of the clutch cover have we continued to drive the car the way it was it would have burnt it up because it would barely move. I've been in Autotech for 50 years never seen a clutch slipping with this much material left on it and the parts in this condition it is obviously a defect with the part and I submitted a claim to Honda and they denied it had I had known Honda would have taken care of it I would have brought it to them.

My 2020 Civic Si had a total clutch failure at <32,000 miles matching TSB22-017 exactly. The vehicle failed to accelerate on a major interstate. The posted speed limit is 65 mph. While attempting to reach that speed the vehicle was revving at >6000RPM in all gears. I was able to reach 50 mph for short periods, but the vehicle would then slow to 45 or lower. An extreme safety risk on a busy highway. When the vehicle was pulled to the shoulder and stopped, the car would not go into 1st gear at all, leaving me stranded on the side of a busy interstate highway. This vehicle has been properly maintained with no modifications and no abusive driving.

Honda CVT transmission fluid seal leak cause by failed torque converter. Car has a perfect maintenance history, all fluid changes done on time with Allen Honda at Bryan Texas including filters associated. Car is garage kept, not driven hard. Always driven in economy mode for smooth efficiency. Failure occurred at 86,165 miles. Significant enough I am reporting this, as it is a safety issue, however don't know if other Honda civics have had this issue. A normal CVT transmission should last 150,000 miles before issues start according to manufacturer (Honda) who built the car. Two photos attached displaying the leak and puddle on my driveway. Leak is a slow drip, fixing it in the morning at a shop which will put me out of almost $3000 not under warranty because car is 6 years of age instead of 5 years. Honda needs to be made aware this is a serious safety concern, had I not caught it, it could have led to crash possibly, or fire from overheating. Leaking areas circled in red. Car currently not drivable, having to tow it in the morning to replace failed parts.

Researched and found this has been a common issue with this make and model. Clutch slippage at random times when accelerating, reported to Honda dealership multiple times, stated there wasn’t any issue with vehicle and denied this was a common issue even though it has been reported by multiple owners of this year/make/model. 3-4 days ago, clutch started disengaging while driving and constantly had the burning friction smell. Fortunately I was able to get my vehicle to the dealership without having to be towed but it was a slow with lots of praying to the car gods. Now the dealership is charging me an outrageous amount to repair, even though I reported this months ago (prior to it getting this bad) and was told there wasn’t nothing wrong with it. My estimate for repairs came to just under $5k for something that should’ve been fixed when it was first reported (which probably would’ve been way less in cost to fix at that time). AND…I had to tell them what the issue was in detail because they treated me like I was stupid. This should’ve been a recall a long time ago with all the reports and complaints from so many people instead of Honda treating people like they’re stupid.

2020 Honda Civic EX-L Bought In 2021, December 2024 car has 102K miles and transmission went out. No warning at all, in the middle of highway. It's now Febuary 2025 a used transmission provided under the power train warranty got installed. That transmission is also failing on the vehicle. Dealership service manager doesn't know what the problem is nor why it is showing failure. I have no update on repair as of now. My only options were to trade in or buy a brand new $10k transmission out of pocket. HIGHLY disappointed and stressed out. - Regular maintenance/service on vehicle performed at shop. - All documentation was provided to dealership and warranty, all documents were accepted. - vehicle never gave me a warning of any failure. - No car, no rental, no replacement. ***dealership and warranty have not provided any information in writing or documentation as requested.

Clutch has begun slipping very badly at 40,000 miles, sometimes to the point of not being able to accelerate. It is worse at highway speeds. There is a known service bulletin 22-017 outlining this issue. According to the VIN, this vehicle was assembled in the Alliston, Ontario, Canada plant and further online research has found multiple others having the same issue on vehicles from the same plant.

TSB 22-017 failing clutch on all M/T civic 2020&2021. Failed on highway almost caused severe accident. Honda is refusing to repair/replace under warranty.

Over the last few months, I noticed that the vehicle had poor acceleration when merging onto the highway. When I tried to accelerate, the RPMs shot up as the turbo kicked in, but the car did not move any faster. Previous to this, I had trouble getting the car into 1st while sitting still (50+ times). The final incident occurred during a short trip to a local store. The engine revved high and I couldn't get over 35MPH. Upon stopping, there was a burning smell coming from the car. I was able to drive it a short distance to a local transmission shop which diagnosed clutch failure. I purchased the car new from a Honda dealer in 2020 and am the only person to drive the car. There are only 70k miles on the car and everyone that I've talked to was surprised that it went out so soon. I don't abuse the clutch (never burned one out before even while living in the mountains). I see that I'm not the only one who has had this issue. Honda should issue a recall and reimburse the owners affected by this defect.

The car has a problem where the clutch prematurely wears out and the cars acceleration cuts out. this happens at different RPM ranges and in all gears. it is very unpredictable. Several others have had to repair their drivetrains and honda claims its due to a production issue with the clutch. they have a dealer service bulletin for this issue however Honda needs to recall the part since this problem doesn't come on gradually. it is a sudden loss of a connection in the drivetrain which has caused several issues merging on the highway.

On March 29, 2023 around 6:30PM on my way home from work, my car stopped me in the middle of I-78. The engine just kept revving when i push the accelerator but won't move forward. I was able to safely pull over to the side. No warning lamps, messages or other symptoms of the problem noted prior to the failure. The following day (March 30, 2023), I dropped off my car to Planet Honda at 2285 US-22, Union, NJ 07083. Tel #'s: (866)226-2469; (609)236-2393. Then, I was informed that the transmission is broken or cannot be fixed, and a new transmission (Part #: 06200-5DJ-040-RM) were ordered and was told that it is covered by warranty. It's been 67 days now (2 months and 6 days) that Honda Corporate cannot give me the timeframe when will my car be repaired after numerous conversations from calls, and texts. My Case Number Honda Corporate Customer Service gave me is: 13736133.

I purchased a brand new 2020 Honda Civic SI in April 2020. Around 24,000 miles, the clutch started slipping. I took the vehicle into a Honda dealership where I purchased the vehicle and was informed the clutch assembly failed and the cost of the repair was $4,400. The dealership told me it was due to abuse of the clutch and clutches are considered wear and tear items so I would be responsible for the entire repair. I have owned 10 manual transmission vehicles prior to this Civic and I have never burned out a clutch--I was able to get more than 125,000 miles from one of my cars before the clutch had to be replaced. There are 15 complaints on this site regarding clutches wearing out on 2020 Honda Civics so could this be a problem on Honda's end. I placed several calls to American Honda customer service and their response is always the same, they don't see a problem with their clutches so they are not going to reimburse me for the repair. After many calls to the dealer, they finally agreed to cover 50% of the repair so ended up paying around $2,300.

Manual transmission slipping when Turbo kicks in and you are unable to accelerate. We are contacting dealer tomorrow as they are closed. No warning lights on Just started happening .

2nd incident of clutch failure within a year and both almost caused a serious accident.

With my car just reached over 19k miles the clutch started slipping when driving on highway, problem continued to become more noticeable overtime. Many drivers with the same car have experienced the same issue with clutch slipping.

Clutch went out at 25k miles - never stalled this car. Have several manual transmission Hondas no problems except this one. Lost engine power and had to pull over on the highway. manufacturer error causing pre mature burnt clutch. This should not be happening. Honda will not take responsibility

Driving on the freeway was downshifting from 6th gear to 5th gear and the shifter locked up snd i could not shift into any gears except neutral. At a high speed i had to coast to the shoulder of the freeway. Luckily i was near an exit. Once i was stopped i tried to turn off and turn the car back on but i still was unable to shift the car into any gear

The contact owns a 2020 Honda Civic. The contact stated while driving 40 mph, he heard an abnormal buzzing and grinding sound coming from underneath the vehicle. There were no warning lights illuminated. The vehicle was taken to the dealer who informed the contact that they could not duplicate the failure. The contact stated that the failure reoccurred while driving. The vehicle was taken back to the same dealer several times, but the dealer was not able to duplicate the failure. The vehicle was then taken to Curry Honda Chicopee (767 Memorial Dr, Chicopee, MA 01020) who informed the contact that they could not duplicate the failure. The vehicle was taken to an independent mechanic who test drove the vehicle and diagnosed that the abnormal sound was coming from the transmission at the main shaft bearing. The manufacturer was made aware of the failure and a case was opened. The vehicle was not repaired. The approximate failure mileage was 8,000.

THE CONTACT OWNS A 2020 HONDA CIVIC. THE CONTACT STATED WHILE DRIVING AT AN UNDISCLOSED SPEED, THE MANUAL CLUTCH FAILED TO ALLOW THE VEHICLE TO SHIFT ABOVE 2ND GEAR WHILE ENTERING THE HIGHWAY. THE CONTACT REVVED THE ENGINE HOWEVER, THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS TAKEN TO THOUSAND OAKS HONDA (3925 AUTO MALL DR, THOUSAND OAKS, CA 91362, (805) 601-7301) TO BE DIAGNOSED.

We purchased our 2020 Honda Civic Si on Jan 16, 2021 with 20 miles on the car. On June 29, 2021 while driving the car it failed to shift into 2nd/3rd. It stopped shifting altogether and we pulled off to see if stopping and starting may fix the issue. Apparently the clutch had blown out as the car wouldn’t even start. We had it towed up to Honda Dealership we purchased it from. They claim that the clutch “exploded” and wouldn’t cover it under warranty even though we have a power train warranty (and even an extended warranty). A clutch should not “explode” after less than 6,000 miles on a car. We drove in normal driving conditions. Online we see this issue repeated around.

HAS NOT BEEN TAKEN IN YET. HOWEVER THIS IS THE SECOND TIME I EXPERIENCED THIS... DRIVING HOME FROM WORK AT 7AM IN NYS, DOWN SHIFTED FROM 6TH TO 2ND GEARS IN REVERSE SEQUENTIAL ORDER TO USE ENGINE BRAKING. NOTICED AS I WAS GETTING OFF THE EXIT RAMP OF THE HIGHWAY, THAT MY CAR WOULD SHOOT UP TO 6K RPM TO BARELY GO 20 MPH... THIS CLUTCH IS A HUGE PROBLEM FOR ALL CIVIC SI THEY PUT THEM IN. THREE YEARS AGO HAD THE SAME ISSUE WITH MY 2017 CIVIC SI. WAS TOLD THAT IT WAS A WEAR ITEM AND WOULD NOT BE COVERED UNDER WARRANTY...

The clutch in my 2020 Honda Civic si started slipping at 8k miles. Please look into defects related to clutch/flywheel/CMC/transmission

TL* THE CONTACT OWNS A 2020 HONDA CIVIC. WHILE DRIVING APPROXIMATELY 35 MPH AND ATTEMPTING TO ACCELERATE, THE VEHICLE SURGED FORWARD. THE CONTACT STATED THAT THE FAILURE OCCURRED TWICE. THE VEHICLE WAS TAKEN TO ATLANTIC HONDA (1375 SUNRISE HWY, BAY SHORE, NY 11706) WHERE IT WAS DETERMINED THAT THE FAILURE OCCURRED BECAUSE THE CONTACT DID NOT KNOW HOW TO DRIVE A STICKSHIFT VEHICLE. THE DEALER REPAIRED THE VEHICLE BY REPLACING THE CLUTCH PRESSURE PLATE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 2,500.
