2020 Honda Civic transmission problems

Filed Nov 2, 2026 · Transmission · MD

My 2020 Honda Civic Sport Hatchback, 1.5L turbo, 6-speed manual, has experienced repeat premature clutch-system failure. The original clutch/flywheel assembly failed at about 34,000 miles. Honda repaired it under TSB 22-017, which addresses supplier production issues causing premature friction-disc wear. Honda advised that updated components were installed. Significant clutch slipping began again in early June 2026. At about 61,500 total miles, only about 27,500 miles after the first repair, transmission removal and clutch-component replacement were required. The onset date entered is approximate. The dealer documented: "Clutch shows sign of Heat Buildup on flywheel and pressure plate with debris inside bellhousing on release bearing. Recommend replacing Pressure plate, Friction Disc, and release bearing." Inspection photos show substantial heat discoloration of the pressure plate/flywheel and heat/glazing of the friction disc. The servicing Honda dealer did not identify driver abuse or improper clutch operation as the cause. No significant fluid contamination or catastrophic transmission damage was identified to me. I have substantial manual-transmission driving experience without comparable repeated failures. Clutch slipping allows RPM to rise without corresponding acceleration, creating a potential unexpected inability to accelerate when merging, entering traffic, crossing intersections or climbing grades. Honda classified this as out-of-warranty wear and tear. I request that the federal safety agency retain and compare this repeat premature failure, including failure of Honda's updated replacement, with other Civic manual-transmission complaints. Repair orders, photos, mileage documentation and the TSB can be provided upon request.

I own a 2020 Civic Si. At about 29,000 the clutch started slipping in higher heats and going up hills. Once I noticed this the clutch degraded very quickly to the point it was unsafe to drive. By very quickly I mean in about 100 miles worth of travel. I notified Honda Corporate and opened a case with them. There is a TSB 22-017 out about the faulty clutches stating the friction material was faulty in some 19-20 models and to replace the clutch and included all parts associated to be replaced. However my car was just one year outside of the warranty even tho it was within the mileage. Since they were going to replace with the same parts that failed, I decided to do the replacement myself with an OEM clutch made for the Type R which is more appropriately matched to the torque of the vehicle and a different flywheel as the factory one increases the wear due to being dual mass. I took pictures of the process for documentation. When the transmission was opened up the friction material had basically disintegrated into chuncks. The pressure plate also seemed to be putting unnecessary amount of pressure on the bearing. Almost like the clamping force was far too much for the hydrolic system to counter and thus caused excessive slippage. Honda was going to charge $2000 to diagnose the clutch and the clutch replacement would have cost $6,000. That is an absurd amount to charge for a known faulty part. Tho the new clutch also required an upgraded CMC, I was about to install a far superior OEM part for 1/3 of the price. I wanted to submit a report in hopes that with enough complaints Honda will do a proper recall before someone in the future loses function of their clutch and potentially has an accident.

I am the second owner of this year and model of Civic. I initially bought it back in 2021 with 14,000 miles on it. The clutch slipped and blew at around 29K miles in 2023. I brought it into a honda dealership and they were at least able to replace the clutch with the SAME CLUTCH under warranty but now it's 2026 and the clutch is going out again. Clutches should not be going out this frequently. I've driven several manuals and if you were to look up this specific year and model, it is a known issue across several forums online and youtube videos for having a "weak clutch". Despite it being a known issue, Honda refuses to announce a recall or make right by their customers who bought this specific year and model. I along with other owners of this specific year and model had our "Good Will" declined after the warranty period ended; how convenient for Honda. It would've essentially cost at least $10K in repairs for an average owner over 5 years on a relatively brand new car. That's more than 30% of the car's worth and value at MSRP.. They keep saying that all of these issues and feedbacks are being reported to the federal safety agency but I honestly believe they're waiting for it to be long enough for warranties to expire and hop they can sweep it under the rug. I've driven Hondas all of my life and have loved their cars but their refusal to do right by this well known issue is leaving a sour taste in my mouth.

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.

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.

My 2020 Civic Si had a total clutch failure 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.
