Coleman UTV 400 Problems

Grinding or Sticking Gears

One of the most commonly reported problems in the Coleman UTV 400 is the gear shift sticking when attempting to change gears, a persistent grinding noise during or immediately following shifting to a new gear, or the inability to shift to the desired gear at all. This issue happened so frequently that Coleman issued a maintenance bulletin in early 2021, with instructions on making an adjustment to the shift linkage, which seems to be the root cause of this sticking and grinding.

Lengthen the Shift Lever

While making an adjustment to the shift linkage works for some units, for others it may not fully solve the problem. For those whose issue is not solved, it is likely that their shift lever does not have enough travel to make a proper gear shift.

Rattling and Squeaking When Driving

Another common complaint with the Coleman UTV 400 is a tendency for the dump bed and tailgate to rattle, or for the UTV to make a squeaking noise when driving. This is most likely due to some of the nuts and bolts not being assembled as tightly as they should be, as well as the fact most new units do not come with grease applied.

Engine Sputtering and Stalling

The Coleman UTV 400 engine might start properly but stall after driving for a while. Your UTV might lose power gradually, sputter, and eventually stall. Common issues that will cause your Coleman UTV to stall are:

  • Fuel starvation
  • Dirty/clogged throttle body

Seat Belt Safety Feature

The seat belt safety feature amounts to a sensor in the seat belts that will not permit the UTV to go faster than around 10 mph unless the driver-side seat belt is buckled. This low speed may be accompanied by a surging or jolting feeling from the UTV.

Bad Fuel Injector

A bad fuel injector can cause your Coleman UTV 400 to run poorly. The engine may misfire, hesitate, or stall. If you suspect that your fuel injector is bad, you should have it checked by a professional mechanic.

Gummed Up Throttle Body

A gummed-up throttle body can cause your Coleman UTV 400 to run poorly. The engine may idle roughly, hesitate, or stall. If you suspect that your throttle body is gummed up, you should have it checked by a professional mechanic.

Engine Not Starting

If your Coleman UTV 400 engine does not start, it could be due to a number of reasons. Some of the most common reasons include:

  • Valves: If the valves are not adjusted correctly, the engine may not start. You should have the valves checked by a professional mechanic.
  • Battery: If the battery is dead or weak, the engine may not start. Check the battery voltage with a voltmeter. If the voltage is below 12.5V, you should charge or replace the battery.
  • Spark Plugs: If the spark plugs are fouled or worn out, the engine may not start. You should check the spark plugs and replace them if necessary.
  • Old Fuel: If the fuel in the tank is old, it may not ignite properly. Drain the old fuel and replace it with fresh fuel.
  • Clutch Issues: If the clutch is not engaging properly, the engine may not start. You should have the clutch checked by a professional mechanic.

Conclusion

The Coleman UTV 400 is a great off-road vehicle, but it has its share of problems. If you are experiencing any of the issues discussed in this article, you should have them checked by a professional mechanic. Regular maintenance and care can help prevent many of these problems from occurring in the first place.
