GMy name is Duane Willett and I filed a Lemon Law claim Dec 8th and was referred to make a complaint to NHTSA by the Texas DMV.The vehicle is coming up on three months of non use due to the Manufacturer issued stop ride which was issued on two separate occasions. I purchased the 2025 Kawasaki ZX-6R vin number [XXX] brand new with zero miles [XXX] and its been subject to NHTSA's recall campaign number for this issue is 25V376 which the vehicle was not available to operate safely for over 30 days due to the #5 metal crankshaft bushing failure. Kawasaki is advised all owners of these bikes to immediately stop riding their affected 2024 through 2026 Ninja ZX-6Rs until the repairs could be completed. The manufacturers solution was not successful, failures continued and another recall was issued for the same problem. NHTSA's campaign number for this recall is 25V798. Bike was take to Family Powersports and the following are the technicians notes. 25-11 CRANKSHAFT BEARING SEIZURE INSPECTION Description SMC 25-11 CRANKSHAFT BEARING SEIZURE INSPECTION Resolution:E FAILED INSPECTION 3 SUPPOSED TO MEASURE 11.

There has been two recalls on my motorcycle. My bike passed the first inspection, i took my bike in two weeks ago for the 2nd inspection, per my Kawaskai dealer my bike did not pass. They informed me that my bike required a new engine. On saturday I call my dealer and was told that Kawasaki re worded the recall fix solution and that my bike passed. My dealer said that the reworded statment makes no sense and that they would not trust the motor on this bike. So if the techs at the dealer are saying that this bike is unsafe to ride why should I just take that this bike is not affected by the recall when I was told it was. I request that Kawaskai replace the engine if they want replace it they can buy the motorcycle back from me for what I owe on it. I will not ride this bike untill the engine is replaces and a notorized letter stating that if I die my wife can sue Kawasaki if related to the recall and they will not dispute the lawsuit.

Safety recall exists for engine stall risk but manufacturer has not provided parts or remedy for over two months. Motorcycle cannot be used.

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.

This motorcycle has been recalled twice. The first recall my bike passed and was good to go. I received another letter about a 2nd recall. Was told it did not pass recall and is out of spec. I am now being told that my bike is passing kawasaki's new spec numbers for the recall. I do not feel safe riding a bike that was deem unsafe to ride and failing a recall. Now all of the sudden new numbers come up and is just aye okay to ride. How would is the consumer supposed to feel about this? A motorcycle is life or death.

I am worried about my safety while riding this bike. There has been two different recalls associated with this bike. The first recall my bike passed and was deemed safe to ride. The second recall my bike failed and the dealer was in contact with kawasaki for a week. The dealership is now stating that since so many bikes were being failed, kawasaki had changed the spec numbers for the crank bearing. My bike is now passing the second recall after it already had failed. I do not feel safe getting on this bike. How is the consumer supposed to feel about this?

This is a follow-up to my prior complaint regarding my 2025 Kawasaki Ninja ZX-6R (VIN [XXX] ). In December 2025 I received another recall notice for Recall 25V798 stating that the prior recall repair may not have properly addressed the crankshaft bushing defect and again instructing that the motorcycle not be ridden. I attempted to schedule the repair but the dealer stated parts are unavailable with no timeline. The motorcycle remains unsafe and unusable despite prior recall remedy.

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.
