2018 Honda Accord: CVT failure

Filed Oct 22, 2026 · Transmission · VA

The CVT automatic transmission is leaking fluid from the transmission input shaft seal. The leak was diagnosed by Pohanka Honda of Fredericksburg, Virginia in October 2026 at approximately 99,400 miles. The dealer recommended replacing the transmission input shaft seal, a repair that requires removing the transmission, estimated at $2,990.90 plus tax. American Honda reviewed the case (Case #[XXX]) and declined goodwill assistance on [XXX]. The repair has not yet been performed. Safety concern: continued loss of transmission fluid can cause transmission failure and a loss of motive power while driving. No crash, fire, or injuries occurred. The problem is ongoing.

My 2018 Honda Accord EX's transmission failed after just 88,000 miles. I have owned 3 Hondas and I never had this experience. All bought a Honda World in Westminster, California. I did some research and spoke to a private transmission service company, Leon's Transmissions, and they told me that in 2018, Honda replaced the old transmission they were using with a CVT transmission. They said that clients who bought Honda Accords in 2018 have had the transmission fail on them between 80,000 - 100,000 miles. They also said that HONDA knew that the CVT in 2018 was a bad transmission but instead of alerting clients, they "chose" to work on improving the CVT transmission for future vehicles. I have taken in my Honda regularly for service which is about 3 times a year. I just had it serviced on May 29, 2026 with an oil and lube, a new air and cabin filter, and brakes. TWO MONTHS later, July 7, 2026 I discovered a "shimmy, grunting" sound when I started it. NO WARNING lamps, messages on my dashboard. I took it into my dealership that I have used since 2002. They told me the transmission had failed, that the warranty was only up to 60,000 miles and that to replace it would cost me $9000.00 dollars. NO DISCOUNTS, NO LOYALTY help, nothing. I am a retired senior and I cannot afford this cost. My dealership said that the car is NOT safe to drive, but to take it to CARMAX and see if I can get anything for the car. What nerve. I believe I should be given some compensation or a new transmission for this gross negligence on Honda. I took in my car for regular service, did not put too many miles on the car in the last 8 years (just 88,000) and feel that they should have CHECKED the transmission each time I serviced the car or alerted me via a recall about the transmission early on.

Vehicle was parked/stationary on semi-flat a school parking lot. When I looked back the vehicles moved. Seems the parking gear did not fully engaged. Regardless vehicle was not in neutral or drive and it still moved forward with no one on it, no keys inside and engine off. Vehicle hit another parked vehicle. Luckily no one got hurt. Seems that the transmission/CVT system may be at fault, but unknown at this time.
