The Kymco 700 UTV, while offering a compelling blend of affordability and utility in the side-by-side market, isn't without its share of reported issues. Understanding these potential problems beforehand can help prospective buyers make informed decisions and current owners troubleshoot effectively. From common mechanical hiccups to electrical gremlins, let's delve into the real-world challenges faced by some Kymco 700 UTV users.

So, What Are People Actually Complaining About? The Real-World Issues

The Kymco 700 UTV, like any machine, can experience a range of problems. While many owners report positive experiences, it's crucial to be aware of potential trouble spots. These issues aren't necessarily universal, but they appear frequently enough in online forums and repair shops to warrant attention.

Starting Issues: One of the most commonly reported problems revolves around starting. This can manifest in several ways, from the engine cranking but failing to fire, to a complete lack of response when turning the key.

Fuel System Woes: Closely related to starting issues, fuel system problems can plague the Kymco 700. This includes fuel pump failures, clogged fuel filters, and even issues with the fuel injectors.

Suspension Concerns: The suspension system, while adequate for general use, can sometimes be a source of concern. Reports include premature wear of bushings, leaky shocks, and even broken springs, especially under heavy loads or in rough terrain.

Electrical Gremlins: Electrical problems are a fairly common grievance across various UTV brands, and the Kymco 700 is no exception. Issues can range from faulty sensors to wiring harness problems, leading to erratic behavior or complete system failures.

CVT Transmission Troubles: The Continuously Variable Transmission (CVT) is the heart of many UTVs, and any problems here can be debilitating. Slipping belts, jerky engagement, and excessive noise are some of the common complaints.

Overheating Issues: Some owners have reported overheating problems, especially during hot weather or when working the UTV hard. This can lead to engine damage if not addressed promptly.

Digging Deeper: Let's Get Specific About Those Starting Problems

Let's start with the frustrating issue of starting problems. Often, the solution isn't as simple as just replacing the battery. Here's a breakdown of possible culprits:

  • Battery Issues: While obvious, a weak or dead battery is the first place to check. Ensure the battery is fully charged and properly connected. Consider a load test to assess its overall health.
  • Faulty Starter Solenoid: The starter solenoid is a small but crucial component that relays power to the starter motor. If it's faulty, it may not engage the starter. Listen for a clicking sound when turning the key; no sound indicates a potential solenoid issue.
  • Bad Starter Motor: The starter motor itself could be the problem. If the solenoid is clicking but the engine isn't turning over, the starter motor may be failing.
  • Ignition Switch Problems: A faulty ignition switch can prevent the electrical circuit from completing, preventing the engine from starting. Try wiggling the key while turning it to see if that makes a difference.
  • Neutral Safety Switch: Most UTVs have a neutral safety switch that prevents starting unless the transmission is in neutral or park. Check the switch and its wiring for damage or loose connections.
  • Fuel Delivery Issues: As mentioned earlier, fuel problems can mimic starting issues. Ensure the fuel tank is not empty and that the fuel pump is working.

Fuel System Headaches: What's Going Wrong and How to Fix It

Fuel system problems can be a real headache, leaving you stranded when you least expect it. Here’s a deeper dive:

  • Fuel Pump Failure: The fuel pump is responsible for delivering fuel from the tank to the engine. A failing fuel pump may cause sputtering, stalling, or a complete inability to start. Replacing the pump is often the only solution.
  • Clogged Fuel Filter: The fuel filter protects the engine from contaminants in the fuel. A clogged filter restricts fuel flow, leading to poor performance and starting problems. Regularly replacing the fuel filter is crucial.
  • Fuel Injector Problems: Fuel injectors spray fuel into the engine's cylinders. Clogged or faulty injectors can disrupt the fuel-air mixture, causing rough running, poor fuel economy, and starting difficulties. Professional cleaning or replacement may be required.
  • Contaminated Fuel: Water or debris in the fuel tank can wreak havoc on the fuel system. Drain the fuel tank and flush the fuel lines to remove contaminants.
  • Fuel Line Issues: Cracked or damaged fuel lines can cause fuel leaks and pressure loss. Inspect the fuel lines for signs of damage and replace them as needed.

Suspension Systems: Keeping the Ride Smooth (Or Trying To)

The suspension is critical for ride comfort and handling, especially on rough terrain. Here's what to watch out for:

  • Worn Bushings: Bushings are rubber or polyurethane components that cushion the suspension joints. Worn bushings can cause excessive play, noise, and poor handling. Replacing worn bushings is a relatively inexpensive fix.
  • Leaky Shocks: Shocks absorb impacts and dampen suspension movement. Leaky shocks lose their damping ability, resulting in a bouncy and uncontrolled ride. Replacing the shocks is usually the best solution.
  • Broken Springs: Springs support the weight of the UTV and absorb larger impacts. Broken springs can cause a significant drop in ride height and a harsh ride. Replacing the springs is essential for safety and performance.
  • A-Arm Problems: The A-arms connect the wheels to the frame. Bent or damaged A-arms can affect wheel alignment and handling. Repair or replacement may be necessary.

Electrical Gremlins: Chasing Those Pesky Shorts and Faults

Electrical problems can be particularly frustrating because they can be difficult to diagnose. Here are some common culprits:

  • Faulty Sensors: Sensors monitor various engine and vehicle parameters. A faulty sensor can send incorrect data to the engine control unit (ECU), leading to performance problems.
  • Wiring Harness Issues: The wiring harness connects all the electrical components. Damaged or corroded wiring can cause shorts, open circuits, and intermittent problems.
  • Loose Connections: Loose or corroded electrical connections can disrupt the flow of electricity. Inspect all connections and clean or tighten them as needed.
  • Blown Fuses: Fuses protect the electrical system from overloads. A blown fuse indicates a potential problem in the circuit it protects. Replace the fuse with one of the same amperage rating.
  • ECU Problems: The ECU is the brain of the vehicle. While less common, a faulty ECU can cause a wide range of electrical problems. Diagnosis and repair often require specialized equipment.

CVT Transmission: Keeping the Power Flowing (Hopefully)

The CVT transmission is a complex system that requires proper maintenance. Here's what to look for:

  • Slipping Belt: The belt is the heart of the CVT, transferring power from the engine to the wheels. A slipping belt results in a loss of power and poor acceleration. Replacing the belt is often the solution.
  • Jerky Engagement: The CVT should engage smoothly. Jerky engagement can indicate a problem with the clutch or belt.
  • Excessive Noise: Unusual noises from the CVT can indicate a problem with the belt, clutches, or bearings. Inspect the CVT components for wear or damage.
  • Worn Clutches: The clutches engage and disengage the belt. Worn clutches can cause slipping and jerky engagement.

Overheating: Keeping Your Cool Under Pressure

Overheating can cause serious engine damage. Here's what to do:

  • Low Coolant Level: Check the coolant level in the radiator and overflow tank. Add coolant as needed, using the correct type recommended by the manufacturer.
  • Radiator Problems: A clogged or damaged radiator can restrict coolant flow. Clean the radiator fins and inspect for leaks.
  • Thermostat Issues: The thermostat regulates engine temperature. A faulty thermostat can prevent the engine from reaching its operating temperature or cause it to overheat.
  • Water Pump Failure: The water pump circulates coolant through the engine. A failing water pump can cause overheating.
  • Air in the Cooling System: Air pockets in the cooling system can prevent proper coolant circulation. Bleed the cooling system to remove air.
