This SxS was designed for serious off-road adventures, offering both performance and the ability to bring along the whole crew. This model really set a new standard for the industry.

Common Issues and How to Troubleshoot

Now, let's be real, even the best machines have their quirks. The 2012 Polaris RZR XP 4 900, while generally reliable, is no exception. Knowing the common issues can save you a lot of headaches (and money!). One of the most frequently reported issues is related to the Polaris Variable Transmission (PVT). Belt wear is common, especially if you ride in challenging conditions or are heavy on the throttle. Slipping belts can lead to a loss of power and can cause the machine to get stuck on the trail. Regular inspection and replacement of the drive belt are crucial for keeping your RZR running smoothly. Another area of concern is the suspension. While the long-travel suspension is a major selling point, the shocks can experience wear and tear over time. Leaks, diminished damping performance, or unusual noises are signs that your shocks might need servicing or replacing. The A-arms and ball joints can also take a beating, especially if you frequently encounter rough terrain. The other typical issues are: overheating, electrical problems, and fuel pump failure. Regular maintenance and timely repairs can prevent these issues from escalating. Always inspect the engine coolant levels, check for leaks, and ensure that the radiator is clear of debris. Electrical issues are often caused by loose connections, corroded wires, or faulty sensors. Careful inspection and troubleshooting with a multimeter can help you identify and resolve these problems. If your RZR is struggling to start or losing power, the fuel pump might be the culprit. Listen for the sound of the fuel pump when you turn the key. If it doesn't sound right, consider checking the fuel pump or getting it replaced.

Troubleshooting Tips

• Belt Slippage: Check for wear and tear, and replace as needed. Keep an extra belt on hand when you go off-roading.
• Suspension Issues: Inspect shocks for leaks, and listen for unusual noises. Service or replace shocks as required.
• Electrical Problems: Check connectors and wires for corrosion or damage. Use a multimeter to locate any problems.
• Overheating: Check coolant levels and radiator condition. Make sure the cooling system is clean and working correctly.

Routine Maintenance: Keeping Your RZR XP 4 900 in Top Shape

Regular maintenance is the secret sauce to keeping your 2012 Polaris RZR XP 4 900 running strong for years to come. Think of it as preventative medicine for your machine! Following a regular maintenance schedule will not only prevent major breakdowns but will also ensure optimal performance and extend the life of your SxS. Start with the basics: oil changes. Changing your engine oil and filter at the recommended intervals is crucial for keeping your engine clean and lubricated. Use the correct type and quantity of oil specified in your owner's manual. Air filter maintenance is also important. A dirty air filter restricts airflow to the engine, which can lead to reduced performance and increased fuel consumption. Clean or replace your air filter regularly, especially if you ride in dusty conditions. Greasing the suspension components is a simple but important task. This will help prevent wear and tear and ensure smooth suspension operation. Check your owner's manual for the location of grease fittings and recommended lubrication intervals. The driveline also requires regular attention. Inspect the CV joints for any signs of damage or wear. Check the condition of the drive belt, and replace it at the first sign of wear. The coolant system also needs regular maintenance. Check the coolant level and condition, and flush and refill the system at the intervals recommended in your owner's manual. The tire pressure and wheel alignment are also crucial for performance and safety. Regularly check the tire pressure and adjust it as needed. Check the wheel alignment periodically to ensure that your RZR is handling and performing correctly. Last but not least: regular inspections! Inspect your RZR before and after every ride. Check all the components for any signs of damage, leaks, or wear. Make a habit of performing a thorough inspection regularly and address any issues promptly.

Maintenance Checklist

• Oil and Filter Change: Every 50-100 hours or as recommended.
• Air Filter Inspection and Cleaning/Replacement: Regularly, depending on conditions.
• Greasing Suspension Components: As specified in the owner's manual.
• Driveline Inspection: Check CV joints and drive belt regularly.
