YAMAHA Complaints

Sudden loss of rear brakes, no pedal at all. No light on . no ABS warning light or loss of brake pressure light , this is scary and dangerous. After replacing the rear master cylinder for loss of pressure, the repair has not fixed the issue, and remains to do the same thing. The bike has been in the shop to have the ABS and Unified brake system serviced and bled, the issue still remains. after bleeding the brakes 20 times there is air getting into the system every time. Note there is no loss of fluid or leaks, but air keeps getting into the system and causing loss of brakes. This is so terrifying to lose the rear brakes on this big bike. I called the dealership again today as I only put 50 miles on the bike since paying them to fix it, I was reassured they fixed it, in the beginning the owner Tom told me there was a connector issue or a sensor, when I picked it up , he said all was well and they just bled it again.

When pulling the front brake lever, if it is pulled lightly the rear brake does not light up at all. It has to have a certain amount of pressure applied to it before the rear brake lights up. The rear brake as soon as it is pressed it lights the rear light up. I have had Petes Cycle in Baltimore MD look at this and they have advised this is how Yamaha has this setup, it has been confirmed and reproduced by dealer. This is a HUGE safety issue in my opinion and should be looked into and Yamaha should be forced to fix this. People that are behind you cannot see if you are slowing or coming to a stop and can cause them to run into the back of you. I can personally be able to attest to this because I have had friends and family that I ride with tell me that they did not know that I was slowing or stopping because they did not see any brake lights. They originally told me; my brake light was out. This is what prompted me to even look into this. No warning lights are active on the dash.

While riding, my abs light lit up and my rear brake became hard to press and rear brakes because inoperable. Had it diagnosed and the abs pump is malfunctioning

The contact owns a 2023 Yamaha MT-09. The contact stated that while stopped at a traffic light, the contact noticed a crack on the frame of the motorcycle. The contact stated that there was no impact to the frame to have caused the crack. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 4,800.

After the remedy to a recent recall was applied on my motorcycle, the ECU reflash has rendered my motorcycle unsafe at low speed until it has warmed up. It has stalled pulling into traffic, sputtered and hesitated. Once the bikes warms up it runs as it should. The tune is not correct for the operating conditions while the engine is not up to proper temperature.

ABS module became inoperable, ABS light "ON", no rear brake at all. After manual cycle of abs unit the brakes works for a short time, becoming inoperable just 2 days later.

The handle bar riser failed and snaped causing a loose handle bar which can cause serious injury. My bike is kept indoors, never left alone and never dropped. It is available for inspection. I almost took it to work and found the issue when inspecting before riding. This has put my life at risk and can easily cause me to run over or collide with other people/ objects. Problem cannot be reproduced. This is a manufacture defect. The bike has not been inspected at this time. Reporting due to urgency and potential for others having the same issue. No warning lights since the object is a solid metal object.

My motorcycle is only 3 months old. The chain adjuster snapped and locked up my rear wheel. This is very dangerous, I was only going 10mph when this happened. Had this happened at highway speeds this could easily have been a fatality as the motorcycle locked the rear wheel and shimmied side to side. There are numerous complaints about this same issue on Yamaha forums, and it is concerning because the dealership is claiming that Yamaha states they have never seen this. The motorcycle is a brand new model, and just released this year. The part is only made out of aluminum. Additionally, because this happened the chain subsequently broke the bracket that holds the adjuster and bent the swing arm that holds the wheel. Now numerous parts are required to be replaced over a small cheap aluminum part they engineered.

At 12 years old and 34,500 miles the rear brakes began feeling soft and eventually traveled to the bottom and the rear brakes stopped working. Front brakes worked normally. Several attempts at bleeding the air out of the rear system only resulted in safe operation for a few days. Eventually the rear brakes stopped working after each air bleeding attempt. The problem is the ABS pump has failed and the combined braking engagement admits air to the rear braking system when the combined braking is engaged through the ABS pump. The only fix is replacement of the ABS pump with a new part at $1,900 retail ($1,600 street price), using a used unit ($450 or so), or repairing the old unit ($550 with shipping to France). I elected to repair the existing unit with a company in France as the bike is out of warranty and several other Super Tenere owners have reported Yamaha is not offering any coverage under warranty or goodwill. I installed this myself and the repair costs would have been much higher had a shop been paid to diagnose and repair this defect. It is probably a $3,000+ repair from a Yamaha dealer The bike was well maintained and brake fluid has been changed every few years as recommended by the manufacturer. This is a know issue and these critical safety systems should function for the life of the vehicle with normal maintenance and use.

Upon deceleration heavy vibration would occur due to defective tire. These were stock parts that came from the factory. Unstable wobble could cause loss of traction and ability to stop in a timely manner.
