Coleman UTV 400 Problems: The Causes and Simple Fixes

The Coleman UTV 400 is a trendy recreational vehicle designed to be a fun and affordable alternative to an ATV. The vehicle has been in production since 2001. With over 10 million units sold worldwide, making it one of the most popular vehicles on the market today.

Despite its popularity, there are many problems that can occur with your Coleman UTV 400, which affect its performance and cause you difficulty when operating the vehicle. These problems include:

1. Rattling and Squeaking

If your UTV is making noise when you drive it, it could be caused by one of two things:

  • Loose parts – Loose parts in the suspension system can cause a lot of noise when driving over bumps or uneven terrain. This can also cause the suspension system to wear out faster than normal.
  • Rubber bushings – Rubber bushings are used in place of metal bushings on some parts of the UTV. They’re designed to help cushion against impacts from rocks or other obstacles. If they are worn out, they will cause a lot of squeaking and rattling.


There are a number of things that you can do to solve this issue.

  • The first thing is to make sure that the tires are properly inflated. If they are not, then you need to ensure they have the proper amount of air.
  • You should also look at the way you are driving your car. If you put too much stress on the suspension system, it may cause this problem. Try driving your vehicle with less stress and see if it helps eradicate or minimize this issue.
  • Another thing that you can do is change the shocks and struts in your Coleman UTV 400. They play an essential role in keeping the car stable while driving. If worn out or damaged, it will definitely lead to rattling and squeaking noises when driving.
  • In addition, make sure that there are no leaks in any part of your Coleman UTV 400’s bodywork because these could also lead to rattling and squeaking noises when driving as well.
  • Use high-quality oil in all moving parts of the vehicle so that they run smoothly and quietly when moving around on rough terrains such as dirt or gravel roads.

2. Engine Sputtering and Stalling

Engine sputtering and stalling is a common problem that occurs on Coleman UTVs. It can be caused by a variety of issues, including fuel starvation, faulty spark plugs, or faulty wiring.

The first symptom that indicates a problem with the engine is when it sputters when you are driving. This happens when the spark plugs are dirty or clogged with carbon build-up. This can also be caused by poor fuel quality or a contaminated gas tank.

The second symptom is when the engine stalls while you are driving. This could indicate either a problem with your engine or an issue in which there is too much pressure inside the combustion chamber for your engine to handle at high speeds.


If you’re experiencing these Coleman UTV 400 problems, there are some steps you can take to correct them.

Step 1 – Inspect the Fuel Float Valve

First, inspect the fuel float valve on your Coleman UTV. This device controls how much fuel flows into your engine and determines when it will start burning fuel. If this device is not working correctly, it could cause your engine to stall out or sputter.

Step 2 – Inspect Your Wiring

Next, inspect your wiring for any damage or frays in it. If there is any damage or frays in the wires themselves, this could lead to problems with electrical interference causing your engine to stall out or sputter.

Step 3 – Replace Your Fuel Filter

Finally, replace your gas filter if it has become clogged over time with dirt and grime from driving around offroad terrain.

If the above steps don’t eradicate these symptoms in your Coleman UTV 400, you should get it checked out by a mechanic as soon as possible.

3. Engine Not Starting

If you have a Coleman UTV, you should know that keeping your engine in good shape is very important. A faulty ignition coil or spark plug is the most common reason an engine is not starting, especially after a cold night.

  • Faulty ignition coil: A faulty ignition coil could be caused by a loose wire or broken terminal. This issue can be easily fixed by replacing the defective part with another one that works properly.
  • Faulty spark plugs: The spark plugs installed in your Coleman UTV might be causing problems because they might be covered by carbon from smoke, dirt, and debris. This prevents them from igniting correctly, causing your engine not to start.


If your Coleman UTV engine is not starting, you can use these steps to repair the problem. If the problem persists, contact a certified repair technician.

Step 1 – Check All Fuses

Check all fuses and make sure they are correctly installed and in good working order. If any fuse is blown, replace it with a new fuse of the same type.

Step 2 – Check the Battery

Check for a dead battery by testing it with a voltmeter. A healthy battery should have 12 volts or more when tested. If not, replace it with a new one of the same make and model.

Step 3 – Check Starter Solenoid

Test the starter solenoid by placing the black wire from its plug into an alternating current (AC) power source like your vehicle’s ignition coil or battery charger. The starter solenoid should click at full speed when tested in this manner. If it does not click at full speed or does not click at all, replace it with an OEM replacement part.

Step 4 – Change the spark plugs

Check your spark plugs for any dirt or soot, and ensure you clean them. If they are worn out, you should replace them.

4. Instability and Poor Handling

The handling, in particular, is not very good. The steering is slow and imprecise, and the turning radius is also not as wide. The stability of the vehicle was also an issue. It will feel unstable at low speeds or when cornering, which can make driving difficult


The handling of this vehicle can be improved by installing aftermarket modifications that will improve its turning radius and increase its stability. The first modification you should consider is adding larger tires to your vehicle. This will allow you to drive over any surface without worrying about getting stuck or spinning out of control.

Another modification that can help improve your UTV’s handling is installing a set of aftermarket shocks on both ends of the chassis. These shocks will help absorb bumps and uneven surfaces to keep your vehicle from tipping over when navigating rugged terrain.

If your UTV has an automatic transmission, it could also benefit from having an upgraded automatic shifter installed in place of the stock one. This will allow you to shift gears more quickly when driving through rough conditions.

5. Transmission Issues

Many different things can go wrong with your Coleman UTV transmission. If you find yourself having trouble with the transmission, then there are several things that you should do right away.

1. Clutch Issues

The clutch on the Coleman UTV 400 is located behind the transmission. When it fails, your vehicle will not start, and you may have to replace it if you want to get back on the road again. Clutch failure can be caused by several things, including a worn or damaged flywheel, friction plate, pressure plate, or a worn or damaged clutch disc.


The Clutch Cable or Chain

The clutch cable or chain connects the clutch pedal and the brake pedal so that they can be used by both pedals at once. If you experience a problem with this piece, then it could be causing issues with your UTV’s clutch system. If this is the case, you may need to replace the cable or chain.

Clutch Springs

Clutch springs help maintain tension in the clutch cable or chain so that it does not slip off its position between each pedal stroke. If these springs are weak or broken, their position may change from time to time, leading to different amounts of pressure being applied throughout each pedal stroke.

2. Grinding or Sticking Gears

This is also another problem with the transmission, where the gears get stuck, causing heat to build up and damage the engine. It’s essential to keep an eye on this and make sure it doesn’t get too hot, which can cause other issues like overheating pistons and bearings.


To fix these Coleman 400 UTV shifting problems, remove the wheels and both halves of the transmission cover plate. Then clean out any debris inside both halves of the transmission cover plate using an air compressor.

Reassemble your engine, replace any parts that have been damaged due to wear and tear, and then reinstall your wheels.
