2014 and 2015 Street Glides
The 2014 and 2015 models were marked by a host of issues, including faulty saddlebag mounts, rough idling and stalling, and head buffeting. These problems led to Harley Davidson recalling over 185,000 bikes in the U.S. alone. The saddlebag mounts were found to fail, causing the saddlebags to come loose and fall off, posing a significant hazard to riders.
2016 Street Glides
The 2016 model had its fair share of issues, with a recall issued for defective clutch master cylinders. The clutch would fail to disengage after the bike had been parked for extended periods. This issue was due to the hydraulic clutch system failing to generate adequate lift, leading to a loss of bike control.
2017 and 2018 Street Glides
The 2017 and 2018 models were notorious for their clutch and brake issues. The primary problem with the brakes was poor caliper performance and frequent seizing up, often thought to be stemming for premature failure with the brake lines. The clutch problems were due to a manufacturing defect with the master cylinder’s internal seal, leading to a build-up of air pressure within the system and preventing it from functioning correctly.

Important Note About The Milwaukee-Eight Oil Pump Recall

The Milwaukee-Eight engine, introduced in 2017, was touted as a significant upgrade for the Street Glide models. However, it suffered from significant oil pump problems, the issue in particular – sumping. This problem, where oil gets trapped in the crankcase and doesn’t return to the oil pan, led to sudden power loss and strain on the engine parts. Harley Davidson issued a recall to address this issue, but it remains a concern for many riders – especially in the face of the strenuous lineage of the Twin Cam engine.
