Battery Drainage Issues
Battery drainage occurs frequently in the Polaris Ranger 570, especially after installing additional accessories. Many owners report finding their batteries completely drained after just a few days of inactivity, even with the ignition turned off. This drainage commonly results from factory LED lights under the dash and added LED switch lights that remain dimly lit for several minutes after key removal. Accessories like GPS units, cell phone chargers, lights, and stereos can draw power continuously when improperly wired. A particularly common issue involves rear lights connected directly to the battery’s positive terminal, which continually drain power when left on. Installing a constant duty solenoid modification helps ensure accessories only draw power when the key is in the on position, significantly reducing battery drain issues.
Faulty Wiring and Connections
Damaged wires and compromised connections frequently cause electrical failures in the Ranger 570 models. Wires positioned near heat sources such as the engine, exhaust system, and throttle body are particularly vulnerable to melting, which creates dangerous short circuits. The proximity of wire harnesses to these high-temperature components often leads to wire casings deteriorating over time, resulting in exposed wires touching and causing electrical malfunctions. Throttle Position Sensor (TPS) failures represent another common electrical issue, causing symptoms like sluggish acceleration or complete starting failure. Professional diagnosis from a certified Polaris mechanic or dealership is essential before replacing the TPS sensor, as symptoms may mimic other electrical problems. Proper insulation and routing of all wiring—especially when adding aftermarket accessories—proves crucial for preventing these electrical system failures and extending the vehicle’s operational life.
Transmission and Drive Problems
Transmission issues rank among the most important challenges for Polaris Ranger 570 owners. The Continuously Variable Transmission (CVT) system, while efficient when functioning properly, presents several common failure points that impact overall vehicle performance and longevity.
Belt Wear and Failure
CVT drive belt deterioration stands as the primary transmission concern in the Ranger 570 models. “Hourglassing” frequently occurs when vehicles become stuck and operators apply full throttle while stationary, causing the drive clutch to spin at maximum speed without moving the belt. This action creates excessive heat at the belt-clutch contact point, resulting in the characteristic hourglass shape and eventual failure. Operating the vehicle at high speeds generates important heat that damages the belt structure over time. Extreme conditions such as mud bogging, rock climbing, or towing beyond capacity accelerate this wear pattern dramatically. Users can extend belt life substantially by using low gear drive range, particularly when traveling below 15 MPH, which reduces stress and heat buildup in the transmission system.
Shifting Difficulties
Shifting problems in the Ranger 570 typically stem from worn or damaged drive belts affecting the transmission’s ability to change gears smoothly. Improper maintenance practices contribute significantly to these issues, with overfilled oil being a common culprit that disrupts normal transmission operation. Mechanical factors like clutch alignment problems or worn shift components create additional resistance during gear changes. Environmental conditions play a role too, as extreme temperatures can affect fluid viscosity and component tolerances. A documented case with a 2016 Ranger 570 revealed intermittent starting and shifting difficulties traced to both a faulty spark plug and excessive oil levels, demonstrating how multiple maintenance factors can compound transmission performance problems. Regular inspection of the clutch system components helps identify potential shifting issues before they become severe.
Suspension and Steering Concerns
The Polaris Ranger 570’s suspension and steering systems are critical for maintaining vehicle stability and safety during operation. While these components are generally robust, owners have reported various issues that can affect ride quality and handling characteristics.
Front End Alignment Problems
Front end alignment issues in the Polaris Ranger 570 aren’t extensively documented in official sources, but many owners experience symptoms that suggest alignment problems. Uneven tire wear patterns often indicate misalignment that develops gradually over time. Pulling to one side during normal driving on flat terrain signals potential alignment issues that require attention. Vibrations felt through the steering wheel typically worsen at higher speeds when alignment is compromised. Following impacts with obstacles or after important off-road use, alignment can shift noticeably, affecting handling characteristics. Regular inspection of tie rods, ball joints, and wheel bearings helps identify potential alignment issues before they become serious problems.
Shock Absorber Failures
Shock absorber performance directly impacts the Ranger 570’s ride quality and handling capability. The owner’s manual provides exact instructions for adjusting front and rear shock absorber springs to maintain optimal vehicle stability. Leaking fluid from shocks indicates seal failure and requires immediate replacement to prevent further damage. Excessive bouncing after hitting bumps suggests worn shocks that can no longer effectively dampen suspension movement. Bottoming out frequently when carrying loads points to shock absorbers that have lost their ability to provide proper support. Environmental factors such as extreme temperatures and harsh terrain accelerate shock wear, particularly in vehicles used primarily for work applications. The factory recommendation emphasizes returning suspension to the lowest setting after removing heavy loads, with identical adjustments applied to both rear wheels for maintaining proper balance and stability.

Regular inspection of hoses, connections, and the radiator itself helps identify potential leaks before they cause catastrophic engine damage.
Faulty Temperature Sensors
Temperature sensor malfunctions frequently trigger overheating issues in these vehicles. Many owners mistakenly replace expensive components like radiators when the actual culprit is the thermistor temperature sensor. Replacing this relatively inexpensive part has resolved overheating problems for many Ranger 570 operators who previously spent money on unnecessary repairs.
Water Pump Failures
The stock water pump impeller often contributes to cooling system inefficiency. Damage to this crucial component restricts coolant circulation throughout the engine, resulting in localized hot spots and general overheating. Inspecting the water pump during routine maintenance prevents unexpected breakdowns during operation.
Air Trapped in Cooling System
Air bubbles within the cooling system create flow restrictions that prevent proper coolant circulation. Trapped air forms pockets that block the normal flow of coolant, leading to inconsistent cooling and engine hotspots. Purging the system using a funnel at the radiator cap allows air to escape and restores proper cooling function.
Prevention Strategies
Monitoring engine temperature gauges during operation provides early warning of potential issues. Addressing cooling system problems immediately prevents more expensive repairs later. For owners of the recalled 2015-2016 models, ensuring recall service has been performed is essential for both vehicle longevity and operator safety.
