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.

Filed Mar 18, 2026

I am submitting a complaint regarding a 2019 Honda CB300R with approximately 1,225 miles. This vehicle is subject to an open recall (NHTSA Recall 19V-412) involving a transmission mainshaft circlip that can detach and cause gear misalignment and shifting issues. Prior to service, the motorcycle exhibited a symptom where it would not shift or operate properly beyond 4th gear. The motorcycle was brought to a Honda dealership for recall service. During inspection, the dealer disassembled the engine and identified internal engine damage, including cylinder scoring and compression loss. The dealer attributed the cause to carbon buildup from old fuel and did not clearly establish whether the transmission issue described in the recall was evaluated as the root cause of the shifting limitation. Given that the recall specifically identifies shifting issues as a symptom of the defect, I am concerned that the original transmission-related issue may not have been properly diagnosed or addressed before recommending extensive engine repairs. I am submitting this complaint to document a potential issue involving recall-related symptoms not being properly evaluated or resolved.

I WAS RIDING THRU A TURN ON MY 2019 HONDA CB300R AND WHEN I STARTED TO ACCELERATE OUT OF IT IN 2ND GEAR IT POPPED OUT OF SECOND AND DOWN INTO NEUTRAL CAUSING ME TO LOSE TRACTION AND FALL ONTO MY LEFT SIDE. LUCKILY I WALKED AWAY WITH ONLY SOME ROAD RASH. I HAD THE RECALL DONE, BUT SOMETHING IS STILL OFF IN THE TRANSMISSION. A FEW DAYS PRIOR THIS HAD HAPPENED TO ME BUT I WAS RIDING STRAIGHT AND I WAS ABLE TO GET THE MOTORCYCLE BACK INTO THE CORRECT GEAR AFTER IT DOWNSHIFTED ON ITS OWN. LAST NIGHT HOWEVER IT HAPPENED IN A TURN, SUPER SCARY NOT SAFE.

Manufacturer communications

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

TheWrench2Feb.21

ENGINE AND ENGINE COOLING; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY

The Wrench - If the right engine cover is leaking coolant on any of the models listed, this could be due to the water pipe causing a gap at the clutch cover side. Replacing the O-ring will not fix the leak. Instead, replace the water pipe.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
