The Yamaha Rhino 700, a pioneering side-by-side ATV, enjoyed immense popularity for its versatility and off-road capabilities. However, like any machine, it wasn't without its flaws. Understanding these common problems is crucial for current owners, prospective buyers, and anyone interested in the history of UTV development.

A Rollercoaster of Success and Scrutiny: The Rhino's Legacy

The Rhino 700 hit the market with a bang, offering a blend of utility and recreational fun that quickly captured the attention of off-road enthusiasts. Its independent suspension, powerful engine, and comfortable seating made it a hit on trails and job sites alike. However, its success was soon overshadowed by a significant safety concern: rollover accidents.

The Elephant in the Room: Rollover Accidents and Safety Concerns

The Rhino's higher center of gravity and relatively narrow track made it susceptible to rollovers, especially during aggressive cornering or on uneven terrain. This issue led to numerous lawsuits and a tarnished reputation for Yamaha.

Why Was It So Prone to Rolling Over?

  • High Center of Gravity: The Rhino's design placed the occupants relatively high off the ground, increasing the risk of tipping.
  • Narrow Track Width: A narrower track width provides less stability compared to wider vehicles.
  • Aggressive Driving: While not a design flaw, the Rhino's sporty nature often encouraged drivers to push its limits, increasing the likelihood of rollovers.

What Did Yamaha Do About It?

Yamaha responded to the safety concerns with several measures, including:

  • Warning Labels: Prominent warnings were added to the vehicle and owner's manual, emphasizing the risk of rollovers and the importance of safe driving practices.
  • Roll Cage Modifications: Yamaha offered roll cage modifications to improve occupant protection in the event of a rollover.
  • Rider Training Programs: Safety courses were offered to educate riders on proper operation and safe driving techniques.
  • Settlements: Yamaha settled numerous lawsuits related to rollover accidents.

The Aftermath: A Lasting Impact

The rollover issue significantly impacted the Rhino's reputation and sales. While Yamaha made efforts to address the problem, the damage was done. The Rhino was eventually discontinued, but its legacy serves as a reminder of the importance of safety in vehicle design.

Beyond Rollovers: Other Common Rhino 700 Issues

While rollovers were the most significant concern, the Rhino 700 also faced other mechanical and maintenance challenges.

Engine Troubles: Power and Performance Hiccups

The Rhino 700's engine, while generally reliable, could experience several issues:

  • Stalling: This could be caused by a variety of factors, including a dirty air filter, clogged fuel injectors, or a faulty idle air control valve.
  • Overheating: Overheating could result from a clogged radiator, low coolant levels, or a malfunctioning thermostat.
  • Valve Problems: Valve adjustments were crucial for maintaining optimal engine performance. Neglecting valve maintenance could lead to valve damage and reduced power.

Transmission Woes: Shifting and Slipping

The Rhino's transmission was another area prone to problems:

  • Hard Shifting: Difficulty shifting gears could indicate low transmission fluid, worn shift linkage, or internal transmission damage.
  • Slipping: Slipping gears could be a sign of worn clutch plates or low transmission fluid pressure.
  • Belt Issues: The CVT (Continuously Variable Transmission) belt was a wear item that required periodic replacement. A worn or damaged belt could cause slipping, reduced power, and even complete transmission failure.

Electrical Gremlins: Lights, Sensors, and Starting Problems

Electrical issues could plague the Rhino 700:

  • Battery Problems: The battery could fail prematurely, especially in cold weather or if not properly maintained.
  • Stator Issues: The stator, responsible for charging the battery, could fail, leading to a dead battery and starting problems.
  • Sensor Malfunctions: Various sensors, such as the throttle position sensor (TPS) and coolant temperature sensor, could malfunction, causing performance issues.

Suspension and Steering: Ride Quality and Handling Concerns

The Rhino's suspension and steering could also present challenges:

  • Worn Bushings: Bushings in the suspension and steering components could wear out over time, leading to sloppy handling and increased noise.
  • Loose Steering: Loose steering could be caused by worn tie rod ends or a loose steering rack.
  • Damaged Shocks: The shocks could lose their damping ability, resulting in a bouncy ride and reduced handling performance.

Maintaining Your Rhino 700: Keeping It Running Smoothly

Regular maintenance is crucial for preventing and addressing many of the common problems associated with the Rhino 700.

Essential Maintenance Tasks:

  • Regular Oil Changes: Changing the engine oil and filter according to the manufacturer's recommendations is vital for engine longevity.
  • Air Filter Cleaning/Replacement: A clean air filter ensures proper airflow to the engine and prevents dirt and debris from entering the combustion chamber.
  • Coolant Flush: Flushing the cooling system periodically helps prevent overheating and corrosion.
  • Transmission Fluid Change: Changing the transmission fluid helps maintain proper lubrication and prevent wear.
  • CVT Belt Inspection: Regularly inspect the CVT belt for wear and tear and replace it as needed.
  • Valve Adjustments: Adjusting the valves according to the manufacturer's specifications ensures optimal engine performance.
  • Greasing: Greasing the suspension and steering components helps prevent wear and maintain smooth operation.
  • Battery Maintenance: Keeping the battery clean and properly charged is essential for reliable starting.
  • Tire Pressure: Maintaining proper tire pressure improves handling, fuel economy, and tire life.

Tips for Preventing Problems:

  • Drive Responsibly: Avoid aggressive driving and excessive speeds, especially on uneven terrain.
  • Avoid Overloading: Do not exceed the Rhino's weight capacity.
  • Store Properly: Store the Rhino in a dry, sheltered location when not in use.
  • Use Quality Parts: When replacing parts, use high-quality OEM or aftermarket components.
  • Seek Professional Help: If you are not comfortable performing maintenance tasks yourself, take your Rhino to a qualified mechanic.

The Aftermarket to the Rescue: Upgrades and Solutions

The aftermarket offers a wide range of upgrades and solutions to address some of the Rhino 700's shortcomings.

Popular Upgrades:

  • Roll Cage Reinforcements: Reinforcing the roll cage can provide added protection in the event of a rollover.
  • Wheel Spacers/Widened A-Arms: These increase the track width, improving stability.
  • Suspension Upgrades: Upgraded shocks and springs can improve ride quality and handling.
  • Performance Exhaust: A performance exhaust system can increase horsepower and torque.
  • ECU Tuning: Tuning the engine control unit (ECU) can improve performance and fuel economy.
  • Skid Plates: Skid plates protect the undercarriage from damage.

Addressing Specific Issues:

  • Stalling: Aftermarket fuel injectors and idle air control valves can improve engine performance and reduce stalling.
  • Overheating: Upgraded radiators and cooling fans can improve cooling capacity.
  • Transmission Problems: Heavy-duty CVT belts and clutch kits can improve transmission performance and durability.
