TRIUMPH Complaints

The contact owns a 2025 Triumph Daytona 660. The contact received notification of NHTSA Campaign Number: 25V531000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The local dealer was contacted, but the vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

Catastrophic structural failure of the motorcycle frame. The lower Left Hand Cradle Assembly (Triumph Part # T2071344), which connects the front engine mount to the rear swingarm pivot, sheared completely through. The fracture occurred precisely at the Heat-Affected Zone (HAZ) of the factory weld. This localized metallurgical defect causes a total loss of chassis integrity. A failure of this primary structural component while at speed would result in an immediate loss of vehicle control, leading to a severe or fatal crash. There were no warning lights or operational symptoms prior to discovering the completely severed steel tube during a visual inspection. The failed component is available for physical inspection. The manufacturer (Triumph) has been notified with high-resolution photographic evidence but refused to investigate the defect or authorize a safety replacement without forcing the owner to pay an out-of-pocket dealership diagnostic fee. This specific weld failure is a documented design flaw on this platform, and the manufacturer actively modified this frame component in subsequent model years, indicating prior knowledge of the structural weakness.

While traveling at approximately 55 mph under normal road conditions, the rear tire experienced a sudden and catastrophic failure. I felt the tire fail first, followed by an immediate loss of stability. The tire split down the center of the tread without warning. There were no prior symptoms, warning signs, or handling issues before the failure. During the loss of control, I then felt the rear of the motorcycle drop further. After the crash, a rear suspension linkage component was found to be cracked at the mounting point. It is UNKNOWN whether the linkage failure occurred before or as a result of the crash sequence, but it was not felt prior to the tire failure. The tire, 180/55ZR17 73W, had been installed in August and had less than 1,500 miles of use. Tire pressure was set to manufacturer-recommended levels prior to operation. The failed tire is available for inspection, and the damaged rear linkage component remains on the motorcycle. The failure created an immediate safety hazard, resulting in a crash and injuries to a passenger. The motorcycle sustained severe damage and is considered a total loss. No prior warnings, messages, or indicators were present before the failure.

The contact owns a 2023 Triumph Rocket 3 GT. The contact stated that while driving at an undisclosed speed, the display screen went blank and the motorcycle unexpectedly shut off. The failure caused another vehicle to rear-end the motorcycle's rear wheel, fracturing the license plate. The contact suffered back pains, but no medical attention was received. A police report was not filed. The contact stated that the vehicle had previously had the battery replaced for the same failure, but the failure persisted. The vehicle was towed to the dealer, who determined that the battery wires were loose and the battery needed to be replaced for the second time. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 4,613.

The brakes, turn signals, and hazards do not trigger the associated components and the controls for these do not work. The check engine light intermittently comes on and off with these symptoms. The front clutch cable has work through the protective housing at the front of the motorcycle against the electrical components.
