I own a 2025 Kawasaki Ninja ZX-6R. The motorcycle is subject to multiple safety recalls related to crankshaft bearing/bushing seizure that can cause sudden engine stall and crash risk. In June 2025, Kawasaki issued Recall 25V376 and instructed owners not to ride the motorcycle until an authorized repair was completed. My motorcycle underwent the recall repair, which resulted in an extended loss of use of approximately two months. In November 2025, Kawasaki issued a second safety recall (25V798) stating that the prior repair may not have properly addressed the defect and again instructed owners not to ride the motorcycle. Kawasaki further stated that parts are not currently available and no repair timeline has been provided. As a result, my motorcycle has now been rendered unsafe and unusable on two separate occasions for the same defect, despite prior recall repair. I am continuing to make payments on a vehicle I am prohibited from operating, with no clear resolution or response from the manufacturer. I am submitting this complaint due to repeated safety-related defects, failed recall remedy, extended loss of use, and lack of manufacturer response.

Was notified by my local motorcycle store Classic Powersports of Rockwall TX that my motorcycle has been recalled for the second time in less than 3 months for possible engine failure and the manufacture has not remedy. I've requested a buy back of the vehicle to purchase another model and I haven't received no response from the manufacture. I'm making payments on a brand new motorcycle that has possible engine ceasing while riding.

Currently the bike is under a "Do not ride" and is inoperable and will continue to be for an extended period of time for myself and many others, with no compensation or alternative during the downtime. Myself and many other riders are stuck with loan payments and/or insurance payments on a bike that is not even a year old in many cases with no word from the manufacturer other than the recommended fix we will be waiting in queue for. This fix is extremely damaging to our value of the $13000-$14000 many of us paid and it will be worth only a fraction of that to resale from here on. Not to mention the reliability of having our engine opened but local mechanics and serviced by them.

ENGINE AND ENGINE COOLING

1 complaint

The contact's son owned a 2025 Kawasaki Ninja ZX-6R. The contact stated that while his son was driving at an undisclosed speed, he was involved in a collision with two other vehicles; the cause of the collision was still under investigation by the California Highway Patrol. The contact was unaware if any warning lights were illuminated. The vehicle was towed to a tow yard and deemed a total loss by the owner's insurance provider. A police report was filed, and injuries as well as a fatality were reported. The contact's son was transported to an area hospital by EMT but was unfortunately pronounced deceased as a result of the accident. Though it was unknown at the time if a specific failure had occurred, upon investigation, the contact concluded that the accident may be related to NHTSA Campaign Number: 25V376000 (Engine and Engine Cooling). The manufacturer was not notified of the accident. The failure mileage was unknown.

While riding at normal speed, I heard a loud popping noise from the engine, followed by immediate power loss. The motorcycle shut off without warning and coolant began leaking heavily near the front wheel. There were no warning lights or symptoms beforehand. The bike had fewer than 3,000 miles on it and was well maintained. I had to tow the motorcycle to the dealership, where a teardown revealed catastrophic engine failure—including internal damage to the crankcase, pistons, and transmission holder. The issue was later confirmed to be related to a manufacturer-issued recall, which had never been disclosed to me prior to the failure. Despite the severity of the issue and the recall connection, the dealership was unable to complete the repair for over two months due to parts delays and poor communication. The vehicle was non-operational the entire time. This failure created a serious safety risk and resulted in over $1,900 in financial losses due to towing, alternate transportation, and financing costs.
