   The product, in the report: 2024 YDX-MORO 07, electric mountain bike

   To the Executive Office, I am writing to formally notify Yamaha Motor Corporation, U.S.A. of a critical, life-threatening safety defect regarding my Yamaha Moro 07 e-bike. Despite my repeated attempts to resolve this through your authorized dealer network, the vehicle remains unroadworthy and dangerous. Product Usage & Hazard Summary This e-bike has been ridden normally on pavement with no aftermarket modifications. Since delivery, it has suffered from a chronic, life-threatening structural defect in the front braking system: - Initial Factory Defect: Shortly after delivery, the front brakes malfunctioned and screeched. I contacted the original retailer, Velofix; their technician attempted to adjust the caliper, but the issue persisted (see last page of Exhibit D: Velofix Communication/Timeline). A subsequent inspection by [REDACTED] (Fairfax, VA) in early summer 2025 revealed that the front fork caliper mounting hole was stripped and could not be tightened, causing the caliper to sit at a dangerous angle. They issued a “DO NOT RIDE” warning, confirming a factory defect in fork alignment. - Dealer Negligence & Near-Crash: Directed by Yamaha to [REDACTED], the bike was held for three weeks in summer of 2025. On my first ride post-service (September 7, 2025), the front caliper bolts backed out mid-ride, nearly causing a catastrophic high-speed crash. [REDACTED] technicians subsequently confirmed the fork threads were completely stripped out and asked to perform helicoil repair, but I refused and reached out to Yamaha customer relations (see Exhibit B: [REDACTED] Technical Assessment and Exhibit C: [REDACTED] admitting fault for misdiagnosis). - Failed Corporate Oversight: I escalated this to your customer relations team. Representative “[REDACTED]” assured me that Yamaha Corporate would monitor a second repair at [REDACTED] to ensure correct installation. Despite this promise, the repair was botched. - Improper Tool Usage & Remediation: In April 2026, [REDACTED] (Dayton, VA), an authorized Yamaha dealer, discovered the mounting bolt had been severely over-torqued— consistent with improper tool usage—which permanently destroyed the structural threads of the replacement fork (See Exhibit A: [REDACTED] Bikes Inspection Report). Following this discovery, the bicycle remained incapacitated at the facility for two months due to a complete breakdown in communication and a lack of actionable guidance from Yamaha’s warranty and service department. During this period, the shop performed a Helicoil repair without my prior authorization or consent. While I did not request this, it serves as further evidence of the structural failure caused by the prior authorized dealers’ negligence, and I have photographic evidence documenting the state of the threads prior to this work (see Exhibit E). Your representative, “[REDACTED],” has refused to resolve this, repeatedly instructing me to return to the shop that botched the work. While Yamaha may attempt to label this remediation as ‘unauthorized’ to avoid liability, such a classification is a bad-faith deflection from the fact that I was left without a functioning vehicle for two months due to manufacturer negligence, and the repair was only performed due to the catastrophic structural failure caused by your network.

   Legal Basis for Demand: Breach of Warranty under the Magnuson-Moss Warranty Act (15 U.S.C. § 2301 et seq.) Yamaha’s position that this is a “third-party dealer issue” is legally invalid: 1. Liability for Authorized Agents: As the manufacturer, Yamaha is legally responsible for the performance of its authorized dealer network. I relied upon Yamaha’s authorization in entrusting my vehicle to your network; Yamaha cannot offload liability for negligent repairs performed by its own agents. 2. Prohibition of Tie-in Requirements (15 U.S.C. § 2302(c)): I have fulfilled my warranty obligations by presenting this product to authorized Yamaha service centers. Conditioning warranty coverage on a return to a dealer that has already demonstrated incompetence is an impermissible requirement under the Act. 3. Right to Remediation: I am entitled to a safe, factory-spec repair. I demand that Yamaha authorize the repair at a competent authorized dealer ([REDACTED]) immediately. Failure to rectify this breach may entitle me to pursue all available legal remedies, including the recovery of reasonable attorney’s fees under 15 U.S.C. § 2310(d)(2). Current Status and Demand As of July 1, 2026, the bicycle remains unroadworthy. This matter is formally escalated to the U.S. Consumer Product Safety Commission (CPSC) and the Virginia Attorney General’s Office. My primary demand is the installation of a new, replacement fork, to be installed by [REDACTED] according to certified factory torque specifications. Failing this, I request a full refund or a full replacement of the defective product. I look forward to your prompt response within 10 business days.

   (07/20/2026) I would like to let you know that Yamaha offered a buyback.
