Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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. …”

NHTSA complaint #11670668, filed 2025-07

“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?”
