2018 Triumph Street Triple S

Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Brakes
Filed Nov 19, 2022

The the front brakes are soft and slow to engage when pulling the brake lever. However, when pulling the lever immediately afterwards, the brakes engage quickly and firmly. After a short period of time without engaging the front brakes, pulling the lever again results in soft and slow engagement. Slow and soft engagement of the front brake is a clear safety issue and may result in an accident. The problem was confirmed by an independent mechanic, Cycles of Silver Spring in Silver Spring, Maryland. The vehicle has been repeatedly inspected, and brake fluids have been replaced three times. The issue is resolved for a short period but then returns.
