The Can-Am Commander 700 is a versatile side-by-side, known for its blend of recreational and utility capabilities. While it's generally a reliable machine, like any off-road vehicle, it's not immune to issues. Understanding potential problems and their solutions can save you time, money, and frustration, allowing you to spend more time enjoying the trails and less time in the shop.

So, What are the Common Gripes with the Commander 700?

Let's dive into some of the most frequently reported problems associated with the Can-Am Commander 700. We'll break down the issues, explore potential causes, and, most importantly, offer some solutions.

1. Belt Slippage and Premature Wear:

This is perhaps the most talked-about issue with the Commander 700 and many other belt-driven ATVs and UTVs. Belt slippage can lead to a loss of power, jerky acceleration, and ultimately, premature belt wear or even failure.

  • The Culprits: Several factors contribute to belt slippage.
    • Improper Break-In: Failing to properly break in a new belt is a common mistake. A new belt needs a "burnishing" period to properly seat within the clutches.
    • Overloading: Exceeding the vehicle's weight capacity puts excessive strain on the belt, leading to slippage and overheating.
    • Aggressive Riding: Constant high-speed starts, heavy throttle use in low gears, and prolonged operation in mud or sand can overheat and damage the belt.
    • Clutch Issues: Worn or misaligned clutches can prevent the belt from engaging properly, causing it to slip. This can be due to worn rollers, springs, or bushings within the clutch assembly.
    • Water Intrusion: Water or mud inside the belt housing significantly reduces friction and leads to immediate slippage.
  • The Fixes:
    • Proper Break-In: Follow the manufacturer's recommended break-in procedure for your new belt. Typically, this involves moderate acceleration and avoiding high speeds and heavy loads for the first few hours of operation.
    • Respect Weight Limits: Always adhere to the vehicle's maximum weight capacity.
    • Ride Smart: Avoid overly aggressive riding habits. Use low gear when needed, and avoid prolonged operation in demanding conditions.
    • Clutch Maintenance: Regularly inspect and clean your clutches. Replace worn rollers, springs, or bushings as needed. Consider upgrading to a performance clutch kit designed for your riding style.
    • Seal Inspection: Inspect the belt housing seals for damage and replace them if necessary to prevent water and mud intrusion. Installing a snorkel kit can also help prevent water from entering the belt housing during deep water crossings.
    • Belt Replacement: If the belt is worn, cracked, or damaged, replace it immediately with a high-quality replacement belt.

2. Overheating:

The Commander 700, like any engine, generates heat. If the cooling system isn't functioning properly, overheating can occur, leading to engine damage.

  • The Culprits:
    • Low Coolant Level: Insufficient coolant reduces the cooling system's ability to dissipate heat.
    • Clogged Radiator: Mud, debris, or insects can clog the radiator fins, restricting airflow and reducing cooling efficiency.
    • Faulty Thermostat: A malfunctioning thermostat can prevent coolant from circulating properly, leading to overheating.
    • Water Pump Failure: A failing water pump reduces coolant flow, leading to overheating.
    • Air in the Cooling System: Air pockets in the cooling system can disrupt coolant flow and reduce cooling efficiency.
  • The Fixes:
    • Check Coolant Level: Regularly check the coolant level and top it off as needed with the correct type of coolant.
    • Clean Radiator: Regularly clean the radiator fins with a soft brush and water. Avoid using high-pressure washers, as they can damage the fins.
    • Test Thermostat: Test the thermostat to ensure it's opening and closing properly. Replace it if necessary.
    • Inspect Water Pump: Inspect the water pump for leaks or damage. Replace it if necessary.
    • Bleed Cooling System: Bleed the cooling system to remove any air pockets. Consult your owner's manual for the proper bleeding procedure.

3. Electrical Gremlins:

Modern ATVs and UTVs rely heavily on electrical systems. Problems with wiring, sensors, or the ECU (Engine Control Unit) can cause a variety of issues.

  • The Culprits:
    • Loose Connections: Vibration and exposure to the elements can loosen electrical connections, leading to intermittent problems.
    • Corroded Wiring: Moisture and road salt can corrode wiring, causing shorts or open circuits.
    • Faulty Sensors: Malfunctioning sensors can send incorrect information to the ECU, leading to poor engine performance.
    • ECU Issues: A faulty ECU can cause a wide range of problems, from starting issues to engine misfires.
    • Battery Problems: A weak or dying battery can cause starting problems and affect the performance of other electrical components.
  • The Fixes:
    • Check Connections: Regularly check all electrical connections for tightness and corrosion. Clean and tighten any loose connections.
    • Inspect Wiring: Inspect wiring for damage or corrosion. Repair or replace any damaged wiring.
    • Test Sensors: Use a multimeter to test the sensors and verify that they are functioning properly. Replace any faulty sensors.
    • ECU Diagnosis: If you suspect an ECU problem, take your vehicle to a qualified technician for diagnosis and repair.
    • Battery Maintenance: Keep the battery charged and in good condition. Replace the battery if it's weak or dying.

4. Suspension Issues:

The Commander 700's suspension is designed to provide a comfortable ride and good handling. However, wear and tear can lead to suspension problems.

  • The Culprits:
    • Worn Bushings: Bushings are used in the suspension to reduce friction and absorb impacts. Over time, they can wear out, leading to excessive play and noise.
    • Damaged Shocks: Shocks can leak oil or lose their damping ability, resulting in a bouncy or unstable ride.
    • Bent A-Arms: Impacts with rocks or other obstacles can bend A-arms, affecting the vehicle's alignment and handling.
    • Loose Ball Joints: Ball joints connect the A-arms to the steering knuckles. Loose or worn ball joints can cause steering problems and instability.
  • The Fixes:
    • Replace Bushings: Replace worn bushings with high-quality replacements. Consider upgrading to polyurethane bushings for increased durability.
    • Rebuild or Replace Shocks: Rebuild or replace damaged shocks. Consider upgrading to performance shocks for improved handling and ride quality.
    • Replace A-Arms: Replace bent A-arms with new ones.
    • Replace Ball Joints: Replace loose or worn ball joints.

5. Starting Problems:

A Commander 700 that refuses to start can be incredibly frustrating.

  • The Culprits:
    • Dead Battery: The most common culprit.
    • Faulty Starter: A failing starter motor won't crank the engine.
    • Fuel Delivery Issues: A clogged fuel filter, faulty fuel pump, or clogged fuel injectors can prevent fuel from reaching the engine.
    • Spark Plug Issues: Fouled or worn spark plugs can prevent the engine from firing.
    • Neutral Safety Switch: A faulty neutral safety switch can prevent the engine from starting if the vehicle is not in neutral or park.
  • The Fixes:
    • Charge or Replace Battery: Charge the battery or replace it if it's dead.
    • Test Starter: Test the starter motor. Replace it if it's faulty.
    • Check Fuel System: Check the fuel filter, fuel pump, and fuel injectors. Replace any clogged or faulty components.
    • Replace Spark Plugs: Replace the spark plugs with new ones.
    • Check Neutral Safety Switch: Check the neutral safety switch. Replace it if it's faulty.
