Latest Fltrx engine complaints
Due to a known manufacturing issue the coil pack wiring was faulty on my motorcycle. It happened twice while I was out riding and both times the motorcycle shut down unexpectedly on me. The second time was almost catastrophic but I was able to ride in neutral to a breakdown lane. I bought the bike in July 2025 and the first issue I had was in august 2025. The issue was brought in, resolved and then a few days later the issue happened again and was once again serviced and resolved in accordance with the Harley Davidson service bulletin. The issue again happened in June 2026 and has been fixed by a different dealer. This is an extremely dangerous issue that should be recalled.
Incident Description: On [[redacted]], I took delivery of a brand-new 2026 Harley-Davidson Road Glide from a certified franchise dealership. Within 15 to 20 minutes of departing the dealership, under normal riding conditions on a well-maintained roadway, the motorcycle suffered a sudden, catastrophic mechanical failure. I observed a large cloud of white smoke trailing heavily from the motorcycle. I immediately pulled over to the shoulder and shut the engine down. Upon inspection, the entire right side of the...

motorcycle was saturated in motor oil. The oil was actively ejecting from the air cleaner housing and rapidly accumulating on the ground in a large puddle. Safety Hazard & Impact: The volume of motor oil ejected from the air cleaner assembly created an immediate, severe traction hazard. Because the air cleaner is situated on the right side of the motorcycle directly upwind of the rear tire path, the atomized and pooling oil thoroughly saturated the right side of the chassis. Continued operation would have inevitably coated the contact patch of the rear tire, introducing an incredibly high probability of an unrecoverable rear-wheel slide (low-side crash), leading to catastrophic vehicle damage and severe bodily injury or death. Resolution & Dealer Action: The motorcycle was recovered by the dealership. Due to the immediate mechanical safety failure and discrepancies with delivery mileage, I demanded the bill of sale be rescinded and my financial assets/trade-in vehicle returned. The dealership reluctantly complied and unwound the deal, but they completely refused to provide a mechanical explanation or diagnostic report for why a brand-new vehicle suffered this severe oil-expulsion failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on Interstate at 70 MPH the motorcycle died after it had already been in the shop to fix issue. I was told issue was a failed update. Once I received the bike back I rode for 3 days before lights started flashing and then in the middle of a ride it lost all power and then gained it back 3 times before dyeing completely on the interstate. The check engine light, battery light and warning light all came on. As this is a driver in Houston TX, power dying on these roads unexpectedly can cause...
