Thousands of Yamaha Wolverine owners just like you have encountered issues with their machines over the years. From engine problems to electrical gremlins to parts that wear out too quickly, the Yamaha Wolverine isn’t exactly known for its long-term reliability.
Before you give up and spend a lot of money on expensive repairs or a new vehicle, learn the truth about the 15 most common 2016 Yamaha Wolverine problems. We’ve rounded up the top problems owners report, what causes them, how to diagnose the issues yourself, and the best ways to get your Wolverine back in working order without breaking the bank.
15 Most Faced 2016 Yamaha Wolverine Problems
The 2016 Yamaha Wolverine, while a popular UTV model, faced several issues that users commonly reported. From mechanical problems to design flaws, owners of this particular year model often sought solutions to a range of concerns. Below are 15 of the most frequently encountered problems associated with the 2016 Yamaha Wolverine.
1) The Engine Does Not Get Enough Power
The engine lacks power. It could be a clogged air filter or a bad spark plug.
- Check the air filter—if dirty, replace it. New filters are cheap and keep your UTV running strong.
- Inspect spark plugs. Replace if corroded or worn. Fresh plugs provide the spark needed for combustion.
With a clean air filter and new spark plugs, your Wolverine should be back to full power in no time.
2) Noise Problems
One of the most common complaints about the 2016 Yamaha Wolverine is excessive noise. The Wolverine’s 708cc engine can generate up to 98 decibels, which is considered “very loud” and potentially damaging. Prolonged exposure to noises over 85 decibels can lead to permanent hearing loss.
To reduce the noise, consider wearing ear protection like noise-canceling headphones or earplugs. You should also avoid exploring trails for long periods, taking breaks when possible. Unfortunately, there’s little you can do to muffle the engine itself.
3) Fuel Tank Problems
If your Wolverine is having trouble starting or stalling out, the issue could be with the fuel tank or fuel pump.
The fuel tank on the 2016 Wolverine is made of plastic and prone to cracking, especially around the fuel inlet where the fuel line connects. If there are any cracks in the tank, it will leak fuel, prevent the vehicle from starting, or cause it to stall out. You may notice a strong fuel smell or see fuel dripping from under the UTV. Unfortunately, the only fix for a cracked fuel tank is replacing it.
4) Hesitation When Accelerating
If your 2016 Yamaha UTV seems to hesitate or bog down when accelerating, especially going up hills, it could indicate a problem with the fuel system or engine. First, check your air filter to make sure it’s clean; a clogged air filter reduces airflow and robs the engine of power. You should also inspect the fuel filter to ensure it’s not blocked, preventing fuel from flowing freely to the engine.
A faulty fuel pump, stuck carburetor float, or gummed-up carburetor jets are other possible issues that can lead to acceleration problems. It’s best to have it checked by a certified mechanic to properly diagnose and repair the issue. Continuing to operate the UTV when it’s hesitating or losing power can worsen the underlying problem and cause permanent damage.
5) Parking Brake Problems
The parking brake on the Yamaha Wolverine has been problematic for some owners. If the parking brake fails to engage or disengage, check the following:
Adjust the Brake Cable
The brake cable may need adjustment. Locate the adjuster nut near the brake lever under the floorboard. Loosen the adjuster nut and pull the slack out of the cable. Retighten the nut and test the brake. Repeat until the brake engages firmly.
6) EPS Issues
The EPS, or electronic power steering, on the 2016 Wolverine can be problematic. The EPS provides power assistance as you turn the steering wheel, making it easier to maneuver.
However, the EPS sensor and module seem particularly prone to failure on this model, resulting in the power steering warning light coming on. When this happens, the power steering stops working, making the vehicle very difficult to steer. Unfortunately, the only solution is to replace the faulty EPS components to restore power steering.
7) Oil Consumption Issues
The biggest issue you’ll likely encounter with your 2016 Wolverine is excess oil consumption. After a few hours of use, you may notice the oil level on the dipstick dropping quickly. A blow-by in the crankcase or oil passing through worn valve guides and piston rings are two common causes of this. To remedy this, you have a couple of options:
- Replace the piston rings and valve seals to tighten up the engine. This requires tearing down the engine, so it can be expensive.
- Use a heavier viscosity oil like 10W-40, which won’t burn off as rapidly. This is a band-aid fix but can help in the short term.
- Check your air filter and replace it if it is dirty. A clogged air filter reduces engine efficiency and can increase oil consumption.
- Make sure you’re not overfilling the tank. Too much oil in the crankcase can get into the combustion chamber and burn off, giving the appearance of high consumption.
Keep a close eye on your oil level and top it off as needed. While higher oil use shouldn’t drastically impact engine life if properly managed, if consumption becomes severe, it’s best to have the engine inspected to avoid long-term damage.
8) Clutch Slipping
The clutch in your 2016 Yamaha Wolverine could start slipping after extensive use, causing the engine RPMs to increase without a corresponding increase in UTV blade speed. This is usually a sign that the clutch needs adjustment or replacement.
9) Glowing Exhaust Issues
If your UTV exhaust seems to glow orange at times, especially at night, it’s likely running too hot. This excess heat can damage engine components over time. A few things could cause an overheating issue:
- Faulty thermostat: The thermostat controls engine temperature. If stuck open, it won’t cycle properly, and the engine overheats.
- Cooling fan issue: The radiator fan pulls air through the radiator to cool the engine. If the fan is malfunctioning or clogged, it won’t cool effectively.
- Low coolant level: Without enough coolant, the engine can’t stay within the normal temperature range. Top off the coolant and check for any leaks.
- Rich fuel mixture: Too much fuel and not enough air means not all fuel is burned, producing excess heat. Have the carburetor adjusted to the proper fuel mixture.
- Clogged air filter: A dirty air filter reduces airflow, creating a rich mixture. Replace the air filter and check it regularly.
- Dragging brakes: Brakes that don’t fully release can produce excess heat. Have the brakes inspected and serviced.
Take your vehicle to a trusted mechanic as soon as possible if overheating continues after attempting solutions. An overheated engine can become a fire hazard if not addressed promptly. It’s better to be safe than sorry!
10) Uncomfortable Seating
The Wolverine’s seat may not be the most comfortable for long rides. After a few hours, the Wolverine’s seat can become irritating and uncomfortable. The seat is quite stiff and narrow, lacking adequate padding for extended periods of operation. Your backside will likely start to feel sore and numb. If you plan on using your Wolverine for more than short trips around your property, you may want to invest in a gel seat pad or replacement seat with extra padding to provide more comfort. Some owners have found that certain third-party aftermarket seats help remedy this issue.
11) Heater Problems
The small engine on your Yamaha Wolverine requires a properly functioning cooling system to operate efficiently. Unfortunately, the radiator and fan that provide cooling for the 454cc engine can develop issues that lead to overheating.
12) Header Pipe Cracking Issues
The header pipe on the 2016 Wolverine has been known to develop cracks, especially around the welds. This can allow exhaust fumes to leak and enter the operator station, creating a safety hazard. Yamaha has issued a recall to inspect and replace the header pipe if cracks are found.
13) Comfort of Riding
Another small point to be made is the angle of the rider’s feet when moving slowly through difficult terrain. Although unpleasant at 2-3 mph, the foot angle is acceptable at 30 mph.
The issue can be resolved by placing a block of wood in front of the gas pedal that is preferably 8 × 10 inches in size. This raises the heel at a convenient angle at any speed. Even though you’d think Yamaha would have realized this before mass-producing the four-wheeler,
14) Excessive Heat Problems
The Wolverine’s powerful engine and cooling system are designed for heavy-duty functions, but in very hot weather, they can still overheat. If temperatures rise above 95 F, the UTV may shut itself off to prevent permanent damage. Unfortunately, the 2016 models in particular were prone to overheating in extreme heat due to a design flaw in the radiator.
15) Displaced Foot Brake
The foot brake on your 2016 Wolverine could become displaced over time due to vibrations and impacts, causing the brake pedal to stick or become loose.
To Fix a Displaced Foot Brake
Release the brake pedal to ensure it’s not stuck. Loosen the brake band by turning the adjustment nut counterclockwise. Locate the brake pedal pivot pin and locking cotter pin. Remove the cotter pin and pivot pin, then lift out the brake pedal.
Clean the brake pedal, pivot pin, and pivot pin housing. Apply grease to the pivot pin and reinstall the brake pedal. Adjust the brake band tension by turning the adjustment nut clockwise while depressing the brake pedal. Insert a new cotter pin to lock the pivot pin in place.
Test the brake pedal to ensure it’s secure but still moves freely. Make any final adjustments to the brake band tension to achieve proper braking power before operating your machine.
How to Fix and Prevent 2016 Yamaha Wolverine Problems?
The Yamaha Wolverine is a popular ride-on vehicle, but it can develop some common issues over time. Here are a few tips to help fix and prevent future Wolverine problems:
1) Check the Fuel System
If your Wolverine won’t start, the fuel system is the first place to check. Ensure the fuel tank is filled with fresh, untreated gasoline and the fuel filter is clean. Air bubbles in the fuel line can also prevent the vehicle from starting. Loosen the fuel cap to release any air pressure, then re-tighten it before trying to start the engine.
2) Keep Oil and Filters Changed
Regular oil changes and air filter replacements are essential to keeping your Wolverine running well. Change the engine oil every 50 hours of use, and replace the air filter once a season or if it looks dirty. Clogged filters reduce engine performance and can cause overheating.
