2024 Honda Civic Powertrain & Transmission Problems

The mechanics at the Honda dealership reported the following on a vehicle that has approximately 27,000 miles on it: 1. The clutch assembly failed and requires a complete clutch kit replacement. 2. The crankshaft oil seal is leaking, which causes oil to be splattered around the engine bay as the crankshaft spins. 3. Timing chain tensioner cover is seeping oil. Honda provided a video showing the exterior of the vehicle only. The video did not show video evidence the clutch was faulty, or that any leaks were present. The safety of the driver and surrounding traffic was put at risk because the vehicle became unreliable (degraded powertrain performance) due to premature failure of the clutch assembly. Leaky crankshaft oil seal and timing chain tensioner cover are leaking lubricants onto hot engine surfaces, causing noxious fumes. These fumes entered the cabin of the vehicle, putting the health of the driver at risk. The problems listed above were confirmed by a service technician at the Honda dealership. The vehicle/components listed above have not been inspected by the manufacturer, police, insurance representatives, or others at this time. There were no warning lamps, messages or other symptoms of the problem prior to the failure. The problem first appeared when the driver was driving home from New Jersey to Virginia on 3/15/2026. She experienced shuddering when the vehicle shifted from first to second gear, then second to third gear. A noxious odor was detected inside the vehicle. The vehicle was towed to the dealership on 3/16/2026.

I was driving up a hill and all of a sudden, my transmission gave out, and I was rolling backwards on a hill. It was terrifying since the brakes barely worked as well. I was rolling down the hill and almost crashed, it was emotionally damaging and hope I never have to live through that again. I had AAA take the car to Honda, and they said that they needed to replace the transmission after only 10,000 miles. I could not believe it and they replaced the transmission since it was covered under warranty.

Cvt transmission unknown if can be inspected. Safety reason is I went to do a lane change on the interstate and pressed the throttle I hear the transmission make a loud noise and would not speed up even with me pressing more on the accelerator. Then 5 seconds later car finally started to speed up No I have brought car in prior to be looked at for the car jumping on slow acceleration they can’t get it to do it when I bring it in. Vehicle has been inspected was advised to change transmission fluid I did issue is still present. No there was no warning lights

The clutch system in my 2024 Honda Civic Sport Touring (VIN: [XXX]) failed completely at 8,126 miles, consisting of flywheel (#22100-5CD-018), friction disk (#22200-5CC-003), pressure plate (#22300-5CC-003), and release bearing (#22810-57A-006) - the exact parts Honda identified as defective in TSB 22-017 due to supplier production issues causing premature friction disc wear. The failure created immediate safety hazards including complete loss of power transmission in traffic, inability to accelerate or maintain speed, unpredictable gear engagement, and risk of being rear-ended when the vehicle suddenly lost power on busy San Diego roads, forcing an emergency roadside stop and towing. Mossy Honda Lemon Grove confirmed the failure (RO# [XXX]), documenting excessive heat causing excessive wear with hot spots all around pressure plate and clutch disc measuring only 5.24mm. Honda denied warranty coverage claiming user error without evidence, and Honda Customer Relations (Case #[XXX]) has provided no substantive response despite these being known defective components. Warning signs first appeared at approximately 4,000 miles with clutch slippage during uphill parking, progressively worsening to include burning smell, difficulty engaging gears, and slippage under normal acceleration before complete failure at 8,126 miles, though no warning lights appeared as manual transmissions lack clutch monitoring systems.
