I own a 2024 Kawasaki KRT ABS ZX6R. They want to do an inspection that will not be sufficient to ride my motorcycle safely.

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)

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.

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.

I purchased a brand new 2024 Kawasaki ZX-6R. At just 3,500 miles, the engine catastrophically failed while I was riding. The bike seized and shut off suddenly without warning. This was months before Kawasaki issued their official “do not ride” notice for this known issue. I received no prior warning and had no opportunity to prevent the failure. The dealership confirmed the failure and linked it to a known internal defect affecting this model, which has since triggered a recall. My bike has now been sitting at the dealership for over 7 months with no resolution, no ETA, and no support from Kawasaki. Despite this being a critical safety issue, Kawasaki has offered no compensation, replacement, or meaningful update. I’ve been forced to continue paying insurance on a bike that was brand new and is now completely unusable. Their “do not ride” letter arrived after the engine was already blown. This is a serious manufacturer defect with real safety consequences. The lack of accountability and customer support is unacceptable.

As you are probably aware of this issue, there is a "do not ride" order in place for my 2024 Kawasaki ZX6R. The dealership confirmed that my VIN has been involved. I just got it, and I am paying for a motorcycle that cannot be used. The issues are below. This is unacceptable. safety recall report revealed certain vehicles may lose engine power during operation due to a seizure of the No. 5 metal crankshaft bushing leading to certain vehicles losing engine power and increasing the chance of a crash. "The bolts holding the crankshaft together in the crank case were over-torqued, and as a result the #5 metal crankshaft bushing can be damaged by improper oil clearance between the crankshaft and the bushing," a description of the issue read. Riders won't receive a warning before the potentially catastrophic issue arises, according to the document.
