Common Polaris Side-by-Side Complaints: What's Bugging Owners?

No side-by-side is perfect, and Polaris models are no exception. While many owners enjoy years of trouble-free operation, some common issues tend to crop up. Knowing what to look for can help you identify problems early and prevent more significant damage down the road.

Electrical Gremlins: Electrical issues are a frequent complaint across various Polaris models. These can manifest in several ways:

Battery Drain: A common culprit is a parasitic draw, meaning something is pulling power from the battery even when the vehicle is off. This could be a faulty accessory, a short in the wiring harness, or a malfunctioning voltage regulator.
Faulty Sensors: Polaris UTVs rely on numerous sensors to monitor engine performance, temperature, and other critical parameters. A failing sensor can trigger warning lights, cause performance issues, or even prevent the vehicle from starting. The Crankshaft Position Sensor (CKP) and Throttle Position Sensor (TPS) are particularly susceptible.
Wiring Harness Issues: Rough terrain and exposure to the elements can take a toll on wiring harnesses. Vibration can cause wires to chafe and short out, while moisture can lead to corrosion and connection problems.

Drivetrain Dilemmas: The drivetrain is responsible for transferring power from the engine to the wheels, and it's a common source of problems:

Clutch Problems: The clutch is a crucial component in Polaris UTVs, especially those with continuously variable transmissions (CVTs). Issues like slipping, grabbing, or premature wear can significantly impact performance. This is often caused by improper belt tension, worn-out rollers/weights, or contamination of the clutch surfaces.
AWD System Failures: Polaris's All-Wheel Drive (AWD) system is a major selling point, but it can be prone to issues. Common problems include failures in the front differential, the Hilliard clutch (which engages the front wheels), or the wiring/solenoids that control the system.
Axle Issues: The axles are responsible for transmitting power from the differential to the wheels. They can be damaged by rough terrain, heavy loads, or aggressive driving. Look for signs like clicking noises, vibrations, or visible damage to the CV boots.

Engine Woes: While Polaris engines are generally reliable, they can still experience problems:

Overheating: Overheating can be caused by a variety of factors, including a clogged radiator, a faulty thermostat, a failing water pump, or a blown head gasket. Ignoring overheating can lead to serious engine damage.
Fuel System Issues: Problems with the fuel system can cause poor performance, stalling, or difficulty starting. Potential causes include a clogged fuel filter, a faulty fuel pump, or dirty fuel injectors.
Oil Leaks: Oil leaks can indicate a variety of problems, from a simple worn-out gasket to a more serious issue like a cracked engine case. It's important to address oil leaks promptly to prevent engine damage.

Digging Deeper: Model-Specific Problems to Watch Out For

While some issues are common across the Polaris UTV lineup, certain models have their own unique quirks and vulnerabilities. Understanding these can help you make informed decisions about maintenance and repairs.

Polaris RZR: The RZR, known for its high-performance capabilities, can suffer from clutch issues, particularly in models with higher horsepower. The stock clutches are often pushed to their limits, leading to premature wear and slippage. Frame cracking has also been reported in some RZR models, especially those subjected to aggressive riding.
Polaris Ranger: The Ranger, designed for utility and work applications, can experience issues related to its AWD system, particularly in older models. The Hilliard clutch, responsible for engaging the front wheels, is a common failure point. Additionally, owners have reported problems with the EPS (Electronic Power Steering) system.
Polaris General: The General, a versatile machine designed for both work and play, can be prone to electrical issues, particularly those related to the wiring harness. The location of the harness, combined with exposure to the elements and rough terrain, can lead to chafing and corrosion.
