What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2023 Suzuki Gsx-S1000, 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.
Reports by component
Ranked by how many owner reports name each component category
- Engine150.0%

Percentages are of component mentions. A single complaint can name more than one component, so these do not sum to the total complaint count.

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
I am submitting a formal complaint regarding a stalling issue with my 2023 Suzuki GSX-S1000GT+. Issue Summary: The motorcycle starts normally when cold. However, once I begin riding and pull in the clutch to stop (such as at a stop sign or traffic light), the engine stalls unexpectedly. The stalling occurs intermittently during this phase and continues until the engine reaches full operating temperature. At that point, the issue no longer occurs. When the engine stalls and I attempt to restart it, it will not restart unless I apply throttle manually. Simply pressing the starter without throttle input results in a no-start condition. Key Observations: Cold Start: Starts up as designed. Initial Riding Phase: Engine stalls when pulling in the clutch to stop. Restart Difficulty: Engine will not restart unless throttle is applied manually. Post Warm-Up: Once at operating temperature, the issue is no longer present. Performance: The motorcycle runs smoothly under load and throttle aside from this stalling condition. Diagnostics: No DTCs are stored and no check engine light is illuminated. Safety Concern: This issue poses a serious safety risk. The stalling is intermittent and unpredictable, which can leave the motorcycle incapacitated in traffic or at intersections. This creates a hazardous situation for the rider, especially when the engine fails to restart without applying throttle—a detail that could easily be overlooked during a critical moment. Technical Assessment: Based on my professional experience, this appears to be a calibration or software logic issue rather than a component failure. The ECU does not seem to manage throttle plate position or idle control properly during transitional warm-up phases. As the motorcycle accumulates mileage, the issue has become more noticeable, suggesting a drift in adaptive values or insufficient compensation in the ECU’s warm-up strategy.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.

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.
