2024 KAWASAKI Ninja ZX-6R Problems & Complaints

A recall has been issued and the motorcycle deemed unsafe to ride. My local dealership has been told to expect at minimum 3 weeks to receive the kit required to conduct the inspection. This issue has been so widespread that the wait time will be substantial. Even then, there will be a substantial loss of resale value as well as risk of further malfunctions after having a local mechanic disassemble and reassemble the engine.

I own a 2024 Kawasaki KRT ABS ZX6R. They want to do an inspection that will not be sufficient to ride my motorcycle safely. The absolute only way for Kawasaki to do that would be to open the engine up to where they could see the actual crank shaft. I feel we are all being jerked around with this. They won't be able to deem it safe simply by inspecting the outer bearing. My motorcycle doesn't even have 300 miles on it. I haven't been able to ride it for almost a month now. It sitting can cause further damage. I'm not sure if my State of Nevada will be one of the States that offer a refund. I am making payments on a motorcycle that I cannot ride. Which is unexceptable.

Manufacturer issued a Do Not Ride recall (25V376) but failed to provide a safe alternative or compensation. This has created a transportation hardship. I also felt very worried that I had been riding this motorcycle which had this serious issue. There is no timeline from the manufacturer on when the problem will be fixed. I'm extremely disappointed with this situation on a one year old bike. -thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am submitting a formal safety complaint regarding my 2024 Kawasaki Ninja ZX‑6R. June 22, 2025, I received two official “Do Not Ride” letters from Kawasaki. These letters state that, due to a possible internal engine defect, the motorcycle is unsafe to operate. My authorized Kawasaki dealer has confirmed that my unit is affected by a manufacturing issue that can cause engine seizure without warning, leading to serious risk of crash, injury, or death. It’s also important to note that Kawasaki notified dealers of this issue on June 4, 2025—over two weeks ago. Despite this, I only received my first formal customer notice on June 22. In the meantime, I was unknowingly operating a potentially dangerous motorcycle. Kawasaki has not provided a fix, recall repair, or buyback option. The bike is currently parked and unusable, while I continue to incur insurance costs, loss of use, and storage burden. The issue appears to stem from an over-torqued crankshaft bolt or related internal engine component — a known problem on other 2024 ZX‑6R units already recalled. I am requesting that NHTSA investigate this case further and ensure all affected motorcycles — including those not yet officially listed by VIN — are promptly included in the recall campaign and made eligible for full safety repair, buyback or additional compensation.

#5 Bearing is out of torque putting engine at risk of seizure. Bike is stored and liquids drained pending recall and repair.

Recall was issued for crankshaft bearing failure and recall was performed and completed. Kawasaki performed the inspection and repair, however kawasaki had failed to adequately fix the issue causing prolonged headaches and paying for something that is unsafe to opperate. All kawasaki is telling people is dont ride but not providing an adequate fix to make the bike safe again or theyre also refusing to buy the bikes back.

Unknown. Fatal motorcycle accident. Based on the police report, one witness said he blew a tire and all witnesses state that he and the bike went airborn. The motorcycle was part of the group of ZX6R's recalled by Kawasaki though its since been salvaged. The officer at the scene confirmed the bikes tire was intact so there's some suspicion that something else happened such as other parts coming off of the bike or the wheel smoking such as if it had locked up.

Vehicle: 2024 Kawasaki Ninja ZX-6R Recall Number: 25V376 VIN: [XXX] Date Received “Do Not Ride” Notice: 6/20/2025 Subject: Recall 25V376 – No Remedy Provided / Loss of Use / Warranty Concerns Dear NHTSA, I am submitting this complaint regarding NHTSA Recall No. 25V376, which applies to my 2024 Kawasaki Ninja ZX-6R due to a potentially catastrophic crankshaft bushing failure. On 6/20/2025, I received a formal “Do Not Ride” notice from Kawasaki Motors Corp. advising me to stop using my motorcycle immediately due to the risk of engine seizure. Since that day, my motorcycle has been parked and unusable — and Kawasaki has not provided any timeline or available remedy for this recall. This means I am now without use of a brand-new motorcycle that I paid for in full, during the entire prime riding season in my home state of Michigan. Even worse, Kawasaki has indicated that the required repair will involve a 20+ hour engine teardown rather than a full replacement. This significantly affects the value, mechanical integrity, and future reliability of my vehicle. I am reporting this to NHTSA because: 1.Kawasaki has not yet provided a fix, nor a timeline, more than 3 weeks after the problem was known. 2.There is no loaner program, compensation, or customer support plan in place. 3.Owners are losing months of use, insurance payments are still required, and the bike cannot be sold or traded. 4.Dealers were issued stop-sale instructions around June 4, 2025, but many continued sales through that time. 5.I fear this recall will result in severe devaluation of affected vehicles, even after repair. I’m asking NHTSA to please hold Kawasaki accountable for timely remedies, appropriate compensation, and warranty protection for affected owners like myself. If manufacturers are allowed to sideline vehicles with indefinite no-ride directives and offer no restitution, that leaves consumers completely unprotected. Thank you for your time [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
