Dear NHTSA Safety Team, I am writing to file an urgent safety complaint regarding my 2023 Royal Enfield Interceptor 650, which experienced a catastrophic failure of the rear braking system while I was riding on a public road. On [insert date], while traveling at approximately 50 mph, I heard a loud metallic noise from the rear of the motorcycle. Shortly after, I attempted to slow down using the rear brake to enter my driveway, but the brake pedal went fully down with no braking response whatsoever. Upon inspection, I discovered that one of the brake pad pins was loose and one of the rear brake pads had completely fallen off, disabling the rear brake. Had I needed to stop suddenly or avoid a collision, this defect could have caused a serious accident or fatal injuries. The motorcycle is under warranty, has not been modified, and is maintained properly. I have contacted the dealer, but given the nature of this failure, I believe this may be indicative of a manufacturing or assembly defect affecting other units as well. I am attaching photographic evidence of the defect and would appreciate it if your office could review this case and advise whether further investigation is warranted. Please let me know if you need additional documentation or if I can assist further in the process. Thank you for your time and for prioritizing vehicle safety.
