TRIUMPH Complaints

The contact owns a 2014 Triumph Thunderbird Motorcycle. The contact stated while riding 60 MPH, the motorcycle lost motive power with the throttle control grip being activated. The contact waited for 20 minutes to restart the motorcycle however, the failure recurred. There was no warning light illuminated. The motorcycle was diagnosed; however, the cause of the failure was not determined. The motorcycle had not been repaired. The manufacturer was made aware of the failure and confirmed that the motorcycle was not included in a recall. The failure mileage was unknown.

The speedometer is 5-7 mph off … it’s registering fast. I feel this is a safety issue and it also adds mileage to the motorcycle. I have contacted the dealer and my concerns fall on deaf ears! I have also sent a email to Triumph USA … no response as yet.

Shifter mechanism has failed suddenly and permanently for the third time. It was repaired under warranty the first two times.

Massive rear brake failure. Known on the forums to be a common issue not remedied by the manufacturer. Rear brake pedal goes to the floor with no brake engaging. Vehicle available for inspection. Dealers won't cover the repair due to no recall issued. No audible or visual warnings of the malfunction before, during or after the occurrence. The occurrence is not isolated. It is a constant issue. No brakes!

1.) I would like to begin by saying that my bike is nearly brand new. Only just over 4k miles. So, the following problem is not in any way a result of the bike being an old or beaten down vehicle. The rear brake light and turn signals failed due to the cable that runs under the rear fender to the rear lights (being suspended by very weak and half attached thin metal tabs) becoming dislodged from their incredibly suspect holding tabs and rubbing on the tire. Thus, stripping and destroying the cable. This is available for inspection upon request. The way the cable is attached is the crux of the complaint I am making. It is unfathomable how this could have not only been designed in the first place, but then approved for production. 2.) If the tire had gotten hold of the cable and ripped it from the bike I could have been thrown from the bike and killed. This is an incredibly unsafe and extremely poorly designed portion of the bike. In addition to the feature having the ability to kill any rider it also has resulted in the lights not working. Not having brake lights or turn signals in the rear can result in other drivers not knowing what you are doing and causing an accident. 3.) To my knowledge this problem has not been addressed in any way by the manufacturer or any other person. I am currently waiting for an upcoming appointment with the dealer to address this issue. 4.) There was no warning of the possibility of this issue. One moment it works perfectly fine, next it is sent into catastrophic failure. Luckly in my case I was uninjured, and the cable was only stripped and frayed and did not get grabbed by the tire. Conclusion This problem is insanely dangerous and can result in death. This feature is so irresponsible and poorly designed it bogles the mind. How Triumph can get away with this without a recall is utterly monstrous. There is no reason for this poor design other than to have it fail on purpose or a complete disregard for any concept of safety.

Motorcycle Shutting down on deceleration. This problem happens when decelerating with the clutch pulled in and shifting from second to first gear. It happens inconsistently and with no discernible Rhyme or Reason. I've been unable to replicate this or determine a set of variables other than second to first gear. Your form requires an incident date but this is something that has happened to me several dozen times.

Intermittently, the engine will stall when coming to a stop while the clutch is disengaged. This is unpredictable and dangerous when it occurs at an intersection or on sloped pavement. The issue drastically increased in frequency when I traveled to an are at a higher altitude.

My front brake is very spongy. I can pull the lever all the way to the bar and the bike will slow, but not nearly enough for hard braking or an emergency situation. Yes, it is available for inspection. My safety, and my passengers safety is at risk from not being able to stop in an appropriate amount of time or distance. Yes, it has been confirmed. We have tried bleeding the brakes on 2 occasions. Both times an ABS bleed and manual bleed was performed. No lamps or other symptoms have been observed, the issue has been present since I have owned the bike.

rear brakes failed dealer bled brakes approximately 6 times, replaced master cylinder on rear. this spring no rear breaks. seems like air leak.

Bike stalls while downshifting. Triumph covered the fix of the map sensor under warranty. A couple months later the bike has redeveloped the same issue. It stalls while downshifting. This is a potentially severe scenario for me as the driver in traffic, and potentially for others if an accident causes follow-on crashes.
