Understanding the Most Common Can-Am Commander Problems
Before you start throwing wrenches, it helps to know what you’re up against. While the Commander is a tough machine, certain issues pop up more frequently than others across different model years. Knowing these weak spots is the first step in effective troubleshooting.
This can am commander problems guide is built from years of trailside fixes and garage experience. We see the same patterns again and again. From the CVT belt giving up the ghost at the worst possible time to mysterious electrical faults that trigger limp mode, we’ve got you covered.
Here are the key areas we’ll be breaking down:
- Drivetrain & Clutch: Often the source of noises, vibrations, and performance loss.
- Engine & Fuel: Overheating and fuel delivery issues can stop a ride in its tracks.
- Electrical System: From dead batteries to confusing error codes.
- Suspension & Steering: The clicks, clunks, and sloppy handling that come from hard use.
Drivetrain & Clutch Woes: The Commander’s Achilles’ Heel?
The drivetrain, especially the Continuously Variable Transmission (CVT), is the heart of your Commander’s performance. It’s also an area that requires regular attention to avoid some of the most common problems with can am commander models.
Symptom: Slipping or Jerky CVT Belt
You hit the gas, the engine revs high, but you’re not getting the acceleration you should. Or maybe it feels jerky and hesitant, especially when taking off from a stop. This is a classic sign of a worn, glazed, or damaged CVT belt.
The Cause: Heat is the number one enemy of a CVT belt. Aggressive riding, towing heavy loads, or running oversized tires without proper clutching can cook a belt quickly. A glazed belt looks shiny and feels hard, losing its ability to grip the clutch sheaves.
The Fix:
- Remove the CVT cover. You’ll need a socket set for this.
- Use a Can-Am belt changing tool to spread the secondary clutch sheaves, which releases tension on the belt.
- Inspect the old belt for flat spots, frayed cords, or missing cogs.
- Before installing a new belt, clean the clutch sheaves with a Scotch-Brite pad and brake cleaner to remove any old belt residue. This is a critical step many people skip!
- Install the new belt, release the tension, and reinstall the cover. Always use a genuine BRP belt or a high-quality aftermarket equivalent for best results.
Symptom: Grinding Noises from the Driveline
A grinding or whining noise that changes with your speed (not engine RPM) often points to a problem in the driveline. This could be a differential issue or, more commonly, a failing prop shaft carrier bearing.
The Cause: The factory carrier bearing that supports the main driveshaft is a known weak point. The rubber support wears out, allowing the driveshaft to vibrate and eventually causing the bearing to fail.
The Fix: This is a more involved job. You’ll need to drop the skid plates and remove the driveshaft to access the carrier bearing. We highly recommend upgrading to a heavy-duty aftermarket carrier bearing with a greaseable zerk fitting. This is one of the best can am commander problems tips for long-term reliability.
Engine & Fuel System Headaches
Your Commander’s Rotax engine is a powerhouse, but it needs clean fuel, proper air, and efficient cooling to perform. When one of these is off, you’ll know it.
Overheating: Why Your Commander is Running Hot
The temp gauge is climbing into the red, or you’re getting an overheat warning on the dash. This is a serious issue that can cause catastrophic engine damage if ignored.
The Cause: The most common culprit is a mud-caked radiator. The fins get clogged, and air can’t pass through to cool the coolant. Other causes include a low coolant level, a failing radiator fan, a bad thermostat, or a faulty water pump.
The Fix:
- Step 1: Clean the Radiator. Don’t just spray it from the front. Get a pressure washer (on a wide, gentle setting) and clean it from the back, pushing the mud and debris out the way it came in.
- Step 2: Check Coolant. When the engine is completely cool, check the coolant level in the overflow bottle and the radiator itself. Top off with the recommended coolant if low.
- Step 3: Test the Fan. Let the machine idle and watch for the fan to kick on as it warms up. If it doesn’t, you may have a blown fuse, a bad relay, or a dead fan motor. Use a multimeter to check for power at the fan connector.
Fuel Pump Failures: The Sudden Stall
Your Commander runs fine for a while, then sputters and dies for no apparent reason. After it sits for a bit, it might start back up, only to die again later. This intermittent behavior is a hallmark of a failing fuel pump.
The Cause: The internal components of the fuel pump wear out over time or can be damaged by debris in the fuel tank. As the pump gets hot, it can seize up, cutting off fuel flow.
The Fix: Replacing the fuel pump is the only real solution. It’s located inside the fuel tank. This job requires care to avoid fuel spills and ensure proper sealing when you’re done. Always use a new tank gasket. The benefits of addressing this early is avoiding a long walk back to camp.
Electrical Gremlins: Chasing Wires and Codes
Nothing is more frustrating than an electrical issue. They can be intermittent and hard to trace, but understanding the common failure points can save you a ton of time.
Diagnosing a Dead Battery or Charging System Fault
You turn the key and get a click, or nothing at all. This is usually a battery or charging system issue. Adding accessories like light bars and stereos can put a heavy strain on the stock system.
The Cause: A simple dead battery is common, but you need to find out why it’s dead. It could be old, have a parasitic drain (something drawing power when the key is off), or the machine’s stator/voltage regulator isn’t recharging it properly.
The Fix:
- Charge and Test the Battery. A good battery should hold a charge of around 12.6 volts. Take it to an auto parts store for a load test to be sure.
- Check Charging Voltage. With a known good battery installed, start the engine. Use a multimeter to check the voltage at the battery terminals. You should see 13.5 to 14.5 volts at idle. If it’s below 13 volts, your charging system has a problem, likely the voltage regulator or stator.
Wiring Harness Rubbing and Shorts
Can-Am is known for routing wiring harnesses in places where they can rub against the frame or other components. Over time, this chafing can wear through the insulation and cause a short circuit, leading to blown fuses or erratic behavior.
The Fix: This is a preventative maintenance task. Take some time to inspect your wiring harness, especially where it passes through the frame or near sharp edges. Add some protective wire loom or wrap key areas with high-quality electrical tape to prevent future issues.
Suspension and Steering: Clicks, Clunks, and Wandering
The parts that let your Commander soak up the bumps take a beating. Wear and tear are normal, but ignoring them can lead to unsafe handling and more expensive repairs down the road.
Worn Wheel Bearings: The Telltale Hum
You hear a humming or grinding noise that gets louder with speed, and you feel a slight vibration through the floor or steering wheel. You may also notice excessive play in the wheel.
The Cause: Water, mud, and sand eventually work their way past the seals and destroy the wheel bearings.
The Fix: Safely jack up the machine and secure it on jack stands. Grab the tire at the top and bottom (12 and 6 o’clock) and try to wiggle it. If you feel any play or clunking, the bearing is shot. Replacing it requires pressing the old bearing out of the hub and pressing a new one in. A wheel bearing greaser tool is a great investment to extend the life of new bearings.
Ball Joint and A-Arm Bushing Wear
Sloppy steering, clunking noises over bumps, and uneven tire wear are all signs of worn-out ball joints or A-arm bushings. These are some of the most overlooked can am commander problems.
The Cause: Constant movement and exposure to the elements simply wear these parts out.
The Fix: To check ball joints, jack up the wheel and use a pry bar under the tire to look for play. For A-arm bushings, try to move the A-arms side-to-side by hand. Any significant movement means it’s time for replacement. Upgrading to heavy-duty aftermarket bushings can greatly increase service life.
Your Can-Am Commander Problems Care Guide: Best Practices for Prevention
The best way to deal with problems is to prevent them from happening. Following a solid maintenance schedule is the key. This is not just about reliability; adopting these sustainable can am commander problems prevention methods is also an eco-friendly approach. A well-maintained machine lasts longer, consumes fewer parts, and reduces waste.
Here are some can am commander problems best practices:
- Regular Washing: Don’t just clean the plastic. Thoroughly clean the radiator, suspension components, and undercarriage to prevent mud from hiding problems and accelerating wear.
- Grease Everything: Your owner’s manual shows all the zerk fittings. Use a quality marine-grade grease regularly to push out water and dirt from your suspension pivots and driveshaft.
- Check Your Fluids: Before every ride, check your engine oil and coolant levels. Simple, but incredibly important.
- Listen to Your Machine: Pay attention to new noises, vibrations, or changes in performance. Catching an issue early is always cheaper and easier than dealing with a catastrophic failure on the trail. This is the core principle of any good can am commander problems care guide.
