Harley Road Glide Problems and How to Fix Them
Most Harley Road Glide faults fall into four buckets: the hydraulic clutch, electrical faults that cut power or trigger a fault alert, Milwaukee-Eight heat and crankcase pressure complaints, and lighting or software faults. Ten federal recall campaigns cover Road Glide model codes, and three of them describe a clutch that may not fully disengage while one describes a loss of electrical and drive power while riding. Check your VIN at nhtsa.gov/recalls before you diagnose anything, because the repair may already be paid for.
This is the index for MotoGearRater's Road Glide repair guides. Each guide gives a diagnostic sequence you can run with hand tools and a multimeter, names the publicly documented recalls that produce that symptom, and tells you which numbers you must look up in service documentation rather than take from a web page.
The model codes this guide covers
Road Glide is a family, not one motorcycle. The codes below are the ones the National Highway Traffic Safety Administration uses in its recall and complaint records, which makes them the codes you need when you search that database yourself. The year ranges are the ranges in which each code appears in those federal records, not a production history.
Model code | Name | Appears in federal records | Engine |
FLTRX | Road Glide | 2015 onward | Twin Cam through 2016, Milwaukee-Eight from 2017 |
FLTRXS | Road Glide Special | 2015 onward | Twin Cam through 2016, Milwaukee-Eight from 2017 |
FLTRU | Road Glide Ultra | 2016 to 2019 | Twin Cam in 2016, Milwaukee-Eight from 2017 |
FLTRUSE | CVO Road Glide Ultra | 2015 to 2019 | Twin Cam through 2016, Milwaukee-Eight from 2017 |
FLTRK | Road Glide Limited | 2020 onward | Milwaukee-Eight |
FLTRXST | Road Glide ST | 2022 onward | Milwaukee-Eight |
FLTRXSE | CVO Road Glide | 2018 onward | Milwaukee-Eight |
FLTRXSTSE | CVO Road Glide ST | 2024 onward | Milwaukee-Eight |
FLTRT | Road Glide 3, a three-wheeler | 2023 onward | Milwaukee-Eight |
FLTRXL | Named in the 2026 recall record | 2026 | Milwaukee-Eight |
FLTRT is the three-wheeled Road Glide 3. Where our guides talk about a side stand, holding the machine upright or a jiffy stand interlock, those steps do not apply to it. A trike also has a parking brake and a reverse gear that a two-wheeled Road Glide does not.
Two dates matter when diagnosing. There was no 2014 Road Glide: the model was dropped for that year and returned for 2015. And Harley-Davidson introduced the Milwaukee-Eight engine on touring models for the 2017 model year, so a 2016 and a 2017 Road Glide do not share an engine, an oiling system or a heat profile. Advice written for one does not automatically transfer to the other, which is the most common way riders get sent down the wrong path in forum threads.
Start here: check your VIN
Two minutes, free, and the only step on this page that can hand you a fully paid repair. The federal lookup at nhtsa.gov/recalls takes a VIN and returns open recalls on that specific motorcycle. Harley-Davidson's customer service line, printed on every notice below, is 1-800-258-2464.
Ten campaigns cover the ten Road Glide codes above across the 2014 to 2026 model years. The VIN lookup is the authority for your machine; this table is a starting point.
Campaign | Road Glide codes and years | Defect | Remedy |
15V216000 | 2015 FLTRX, FLTRXS | Clutch master cylinder may lose the ability to generate enough lift to disengage the clutch, especially after the machine has been parked for an extended period | Flush the clutch system and rebuild the clutch master cylinder |
15V427000 | 2015 FLTRX, FLTRXS, FLTRUSE | Saddlebag may separate from the motorcycle | Replace saddlebag mounting receptacles |
16V471000 | 2016 FLTRX, FLTRXS, FLTRU | Same clutch defect, with gas in the clutch fluid | Inspect for gas in the fluid, then flush and rebuild the master cylinder |
17V333000 | 2017 FLTRX, FLTRXS | Oil cooler line clamp incorrectly installed, possible sudden oil loss toward the rear tire | Inspect and correct the clamps |
18V734000 | 2017 to 2018 FLTRX, FLTRXS, FLTRU, and 2018 FLTRXSE | Clutch may not disengage, which can result in loss of control | Install a new secondary clutch actuator piston assembly |
19V574000 | 2017 to 2019 FLTRU, 2016 to 2019 FLTRUSE, with a detachable Tour-Pak conversion kit | Kit omitted the rear red reflectors | Install replacement reflectors |
22V781000 | 2020 to 2022 FLTRX, FLTRXS, FLTRK, FLTRXSE, and 2022 FLTRXST | Software error can illuminate the brake lights without the rider braking | Software update |
23V672000 | 2023 FLTRXSE | Rear brake line may chafe on the exhaust and leak fluid | Replace the rear brake line clamp |
24V672000 | 2024 FLTRX, FLTRXSE, FLTRXSTSE | Voltage regulator output wire can rub the crankcase and short, causing loss of electrical power and drive power | Inspect and repair the harness, add a retention strap |
26V270000 | 2024 to 2026 FLTRX, 2026 FLTRT and FLTRXL, built with a particular airbox baseplate | Blocked airbox breather port pressurises the crankcase. Oil may eject from the fill spout when the dipstick is removed | Inspect the breather port and clear any blockage |
Those descriptions are the manufacturer's own, as filed with the federal regulator. Two of the ten, 19V574000 and 22V781000, are noncompliance recalls rather than safety defect recalls. Note also that 26V270000 applies only to machines built with one specific airbox baseplate, so the VIN lookup decides, not the model year.
Safety note from that last one: if your machine is covered by 26V270000, the crankcase can be pressurised. Release that pressure before pulling the dipstick, keep your face away from the fill spout, and wear eye protection.
Find your symptom
What the bike is doing | Where to start |
Dead, clicks, or cranks and will not fire | |
Check engine light, fault alert, reduced power | |
Creeps or lurches in gear, clutch bites earlier as it heats, hard to find neutral | |
Charging fault, battery flat after standing | |
Oil in the airbox, oil pushed out of the fill spout, crankcase pressure | Read recall 26V270000 above first, then Harley engine, primary and transmission fluid |
What Road Glide owners actually report
As of September 2026 the federal complaint database holds 104 owner complaints filed against the ten Road Glide codes above for the 2014 through 2026 model years. Counting every complaint that names a given component, the largest clusters are electrical system at 35, engine at 28 and power train at 23. Thirty-two of the 104 name more than one component, so those counts overlap and do not sum to 104.
Read that as a map of where to look first, not as a failure rate. Complaints are self-selected: riders file when something frightens them, and nobody files to report a motorcycle that worked. The database does not publish how many machines were built, so no percentage can honestly be calculated from it. What it does show is that electrical, engine and clutch complaints dominate the Road Glide record, which is also where the recalls sit.
What we will not print
You will not find a torque figure, a fluid capacity, a valve clearance or a service interval anywhere in this section. Those values live in Harley-Davidson's service documentation for your specific model year, and a wrong one costs you a stripped crankcase thread or a ruined clutch. Every guide carries a short table naming the values that job needs and the document that holds them. That table is deliberate and it is the part of these guides we are least willing to compromise.
Tools that cover most of this section
A digital multimeter, which does more Road Glide diagnosis than any other tool. Start with using a multimeter on a motorcycle.
A Torx and hex set, because Harley fasteners are mostly Torx.
A battery tender, since many mystery electrical faults on a bike that sits are a tired battery pretending to be something more interesting.
A code reader that speaks Harley's protocol, or a dealer appointment, for anything throwing a fault alert.
Frequently asked questions
What are the most common Harley Road Glide problems?
Judged by the public federal complaint record for the 2014 to 2026 Road Glide model codes, the largest clusters are electrical system at 35 complaints, engine at 28 and power train at 23, out of 104 total. In practice that means hydraulic clutch faults, wiring and charging faults that cut power or trigger a fault alert, and Milwaukee-Eight heat and crankcase pressure complaints. Three of the ten recall campaigns covering Road Glide codes describe a clutch that may not fully disengage.
How do I check if my Road Glide has an open recall?
Enter your VIN at nhtsa.gov/recalls. The lookup is free, specific to your motorcycle rather than your model, and shows recalls that have not yet been performed. Recall work is done at no charge by a Harley-Davidson dealer. Harley-Davidson's customer service number, given on every recall notice, is 1-800-258-2464.
Which Road Glide years had clutch problems?
Federal campaigns describing a clutch that may not fully disengage cover 2015 FLTRX and FLTRXS under 15V216000, 2016 FLTRX, FLTRXS and FLTRU under 16V471000, and 2017 to 2018 FLTRX, FLTRXS and FLTRU plus the 2018 FLTRXSE under 18V734000. The first two flush the system and rebuild the clutch master cylinder. The third installs a new secondary clutch actuator piston assembly.
Is a 2017 Road Glide the same as a 2016 one to work on?
No. Harley-Davidson introduced the Milwaukee-Eight engine on touring models for 2017, replacing the Twin Cam. Engine, oiling and cooling differ, so a procedure or specification written for a 2016 Road Glide should not be applied to a 2017 without checking.
What is the FLTRT Road Glide 3?
FLTRT is the three-wheeled Road Glide, which appears in federal records from the 2023 model year. It is included in this section because it shares the Road Glide name and much of the electrical architecture, but any instruction involving a side stand, holding the machine upright or balancing it does not apply, and it has a reverse gear and parking brake a two-wheeled Road Glide does not.
Why does this site not publish Harley torque specs?
Because they cannot be verified from a free source and cannot be worked out after the fact. A correctly installed fastener does not reveal what it was tightened to. Publishing a number we could not source would be guessing with your crankcase, so each guide names the value you need and the document that holds it instead.
