Kymco, a Taiwanese manufacturer known for its scooters and ATVs, has also ventured into the side-by-side (SxS) market. While Kymco SxSs offer a compelling price point and a reputation for reliability in other vehicle categories, potential buyers and current owners often encounter specific issues. Understanding these common problems is crucial for making informed purchasing decisions and ensuring proactive maintenance to maximize the lifespan and performance of your Kymco side-by-side.

What are Some Typical Kymco SxS Issues?

Let's dive into some of the more frequent issues Kymco SxS owners have reported. These aren't necessarily universal problems, but awareness can help you troubleshoot and address them effectively.

1. Clutch Concerns:

The clutch system seems to be a recurring point of concern for some Kymco SxS owners. Symptoms can range from belt slippage during acceleration, especially under heavy loads or on steep inclines, to jerky engagement and even premature clutch wear.

  • Belt Slippage: This often manifests as a loss of power and a high-pitched squealing sound. It can be caused by a worn or glazed belt, improper belt tension, or contamination from oil or debris.
  • Jerky Engagement: A jerky start or engagement can be frustrating and make precise maneuvering difficult. This can be due to a sticky or worn clutch actuator, or issues within the clutch assembly itself.
  • Premature Wear: Some owners have reported needing to replace their clutch belts more frequently than expected. This can point to underlying problems with the clutch system or driving habits that put excessive strain on the belt.

Possible Solutions: Regular inspection and cleaning of the clutch components, ensuring proper belt tension, and using high-quality replacement belts can help mitigate these issues. Consider upgrading to a heavier-duty clutch system if you frequently operate in demanding conditions.

2. Electrical Gremlins:

Like many modern vehicles, Kymco SxSs rely heavily on electrical systems. Consequently, electrical problems can be a source of frustration.

  • Battery Issues: Some owners have experienced issues with batteries not holding a charge or failing prematurely. This can be due to a parasitic drain, a faulty charging system, or simply a low-quality battery.
  • Wiring Problems: Exposed or poorly routed wiring can be susceptible to damage from the elements or abrasion, leading to short circuits or other electrical malfunctions.
  • Sensor Failures: Modern SxSs use various sensors to monitor engine performance and other critical systems. Sensor failures can trigger warning lights and potentially affect engine operation.

Possible Solutions: Regularly check the battery's condition and connections. Inspect the wiring harness for any signs of damage and repair or replace damaged wires. Consider investing in a battery tender to maintain optimal battery charge during periods of inactivity. Regularly check the error codes from the ECU to see if any sensors are malfunctioning.

3. Suspension Woes:

The suspension system is crucial for a comfortable and capable ride, especially when tackling rough terrain. Some Kymco SxS owners have reported issues with their suspension components.

  • Shock Absorber Problems: Leaking shock absorbers, worn bushings, or inadequate damping can lead to a bouncy or unstable ride.
  • A-Arm Bushing Wear: The bushings in the A-arms are subjected to a lot of stress and can wear out over time, resulting in excessive play and poor handling.
  • Spring Sag: Over time, the springs can sag, reducing ground clearance and affecting the vehicle's ride height and handling.

Possible Solutions: Regularly inspect the shock absorbers, bushings, and springs for any signs of wear or damage. Replace worn components with high-quality replacements. Consider upgrading to aftermarket suspension components for improved performance and durability, especially if you frequently ride in challenging conditions.

4. Engine Performance Hiccups:

While Kymco engines are generally considered reliable, some owners have reported occasional engine performance issues.

  • Starting Problems: Difficulty starting, especially in cold weather, can be a sign of a weak battery, a faulty starter motor, or issues with the fuel system.
  • Rough Idling: A rough or erratic idle can indicate problems with the fuel injectors, the air intake system, or the engine's control system.
  • Power Loss: A noticeable loss of power can be caused by a variety of factors, including a clogged air filter, a faulty fuel pump, or a malfunctioning sensor.

Possible Solutions: Ensure the battery is fully charged and in good condition. Check the air filter and replace it if necessary. Inspect the fuel system for any signs of leaks or contamination. Consult a qualified mechanic for diagnosis and repair of more complex engine problems.

5. Plastic Body Panel Concerns:

While not a performance issue, some owners have noted the durability of the plastic body panels on certain Kymco SxS models.

  • Cracking and Breaking: The plastic can be prone to cracking or breaking, especially in cold weather or after impacts.
  • Fading: The color of the plastic can fade over time, particularly when exposed to direct sunlight.

Possible Solutions: Be mindful of the plastic's fragility, especially in cold weather. Consider applying a protective coating to help prevent fading. When replacing damaged panels, consider aftermarket options made from more durable materials.

Addressing Kymco SxS Problems: A Proactive Approach

The key to minimizing problems with your Kymco SxS is a proactive approach to maintenance and care. Here's a breakdown of essential steps:

  • Regular Maintenance: Follow the manufacturer's recommended maintenance schedule diligently. This includes changing the oil, checking the filters, lubricating the chassis, and inspecting the brakes.
  • Thorough Inspections: Regularly inspect your SxS for any signs of wear, damage, or leaks. Pay close attention to the clutch, suspension, and electrical systems.
  • Proper Storage: Store your SxS in a dry, sheltered location to protect it from the elements. Use a battery tender to maintain optimal battery charge during periods of inactivity.
  • Cautious Driving: Avoid aggressive driving habits that can put excessive strain on the vehicle. Be mindful of the terrain and drive accordingly.
  • Early Intervention: Address any problems promptly before they escalate into more serious issues. Ignoring warning signs can lead to costly repairs down the road.

Kymco SxS Model-Specific Issues

It's important to remember that the specific problems encountered can vary depending on the Kymco SxS model. Some models might be more prone to certain issues than others. Researching specific models and forums dedicated to those models can provide valuable insights into potential problems and solutions. For example, the UXV 500 and UXV 700 models have been discussed more frequently in online forums concerning clutch issues compared to newer models.
