Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Every now and then the engine will stall out during stop & go traffic or when you pull into a parking lot with the clutch pulled in & no throttle. This has happened three times in the last month. I hear by internet threads that harley is aware of this situation and has chosen not to make this public to owners. Do we wait till someone gets killed to address this critical issue?.”

NHTSA complaint #11065355, filed 2018-01, 4,500 miles

“Oil pressure switch worked it's way out only indicating low pressure by the time while riding. I got it to my dealer after they told me to bring it in when parked the switch was out far enough to cause the oil to pour out. If this had happend when riding in my opinion the engine would sieze causing the wheels to lock and throw the rider off the motor cycle causing serios injury or death to the rider and causing an accident of the vehicles behind. This is on the new milwalkee 8 engine. Have read complaint of the failure but not on it working it's way out. …”

“While riding at 55mph the bike suddenly lost oil pressure and started blowing an enormous amount of smoke out the exhaust and the breather tubes in the intake. This caused oil to come out and blow back under the rear tires which could have resulted in loss of control. I was able to stop and when I checked the oil the cap blew out into my hand because of crankcase pressure. The oil level showed it was very low so I added 2 3/4 quarts of new oil. …”
