What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2023 Kawasaki ZX400, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
I was leaving a stop light in road mode. I took off smoothly with no rapid acceleration. I was in second gear and was going roughly 20 mph, when suddenly the bike stalled and the rpms immediately dropped. I was jerked forward but stood on the bike. However, it caused me to drop it on my right side, causing the right side fairings, exhaust pipe, even frame and bar ends to be scratched. I did get injured with a fractured hand. Luckily there was no traffic around and no others were in danger. There was no warning lamps on the dash at the time, and it hasn't happened so far. I have not got the bike checked yet, but definitely plan on it after hearing of the recall.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
