Now that you know the basic features of the Honda Rincon 680 (TRX680FA8), let’s move to the vehicle’s most common problems and their solutions.

1. The Problem of Electric Shift in Vehicle:

The electric shift is one of the most commonly reported issues with the Rincon. This issue can be due to various causes, but the most common factor is bad grease. When the grease in the vehicle becomes hardened, it can make it difficult to shift between gears. 

Another major issue linked with electric shifting is a grinding noise while shifting between gears. This noise can make shifting into the reverse or drive gears difficult. This issue iQs especially troubling for those accustomed to a smooth, quiet ride. 

Finally, some Honda Rincon 680 models are reported to lack low gear. This can be a major inconvenience for those who need to engage lower gears for off-road conditions.

10 Most Common Honda Rincon 680 Problems- How to Fix


  • Difficulty in shifting into drive or reverse
  • Rattling noise when attempting to shift gears
  • Unusual noise when driving at higher speeds

How To Fix:

There are a few possible solutions to the Honda Rincon 680 electric gear shift problem. One common issue is poor grease on the components, causing grinding noise and difficulty in shifting gears.

Properly greasing the components or replacing old grease with a new ones can help resolve this issue. This can make it easier to drive or reverse the gears in the vehicle and eliminate the rattling noise.

Another possible cause of the problem is an improperly adjusted shift cable. If the shift cable is out of adjustment, it may not fully engage the gear and can rattle when attempting to put it in gear.

To fix this, adjust the shift linkage/cable properly to make a positive shift between D – N – R. This should resolve the rattling noise and make it easier to shift gears.

It is important to note that if these solutions do not fix the issue, it may be due to a more severe problem with the gear shift motor, sensor, or electrical wiring. In such cases, taking the vehicle to a certified Honda mechanic for a thorough diagnosis and repair is recommended.

2. The Problem of Fuel Injector:

Honda Rincon 680 is an upgraded ATV vehicle that holds a powered fuel injector. But sometimes, there arises an issue with the fuel injector due to common reasons.

The reasons include the presence of hard starting of the vehicle, poor idling, and excess consumption of fuel which can damage the fuel injector.

How To Fix:

If your Rincon 680 is facing an issue with the fuel injector, you can fix it by cleaning it. You can seek help from the user manual, where instructions are mentioned about cleaning and maintaining the fuel injectors of Rincon 680.

3. The Problem of Speed Sensor:

The speed sensor is an essential component of the Rincon 680, and it helps measure the vehicle’s speed by measuring the wheel shaft’s rotation in the transmission.

Unfortunately, some users of the Rincon 680 have reported issues with the poor functioning of the speed sensor due to poor maintenance or damage to the sensor.

The most common issue is that the speed sensor of the Rincon 680 can become stuck in one position, either showing too fast or too slow speed reading.

The sensor might have become damaged due to wear and tear. Another common issue is that the speed sensor might malfunction and show false speed readings.

A Honda Rincon 680 user reported that this problem occurs mainly when he is at a standstill, although it has occurred while moving slowly. The speedometer on the Rincon starts jumping erratically, showing speeds such as 57mph, 3mph, 80mph, 5mph, and so on. This issue occurred thrice during the rider's 15 rides this summer.

The first time it occurred, the rider was on a rugged and rocky trail, which resulted in a ripped CV boot. The second time, the rider was stopped waiting for other riders to catch up, and the third time the rider had gone through a couple of streams and was waiting for others.

The problem is quite frustrating because it causes the anti-creep function to disengage and the speed governor to kick in, killing the engine. Upon diagnosing the issue, the DTC blinks one long and two short, indicating code 12 (front VSS no signal).

It’s worth noting that the Honda Rincon 680 ATV may log a code for the front wheel speed sensor (WSS) when the rear wheels are turning at high speed, and the computer detects that the front wheels aren’t turning as fast.

This happens because the computer “assumes” there’s an issue with the front WSS. If you encounter this scenario, don’t be alarmed; it could be a false positive.

How To Fix:

If you’re experiencing a speed sensor problem with your Honda Rincon 680 ATV, you can follow the steps below:

  • STEP 1: Ensure the speed sensor is securely attached to the vehicle and the wires are correctly connected.
  • STEP 2: Check for any signs of damage or wear to the wiring and replace any faulty components.
  • STEP 3: If the above steps don’t solve the problem, you must replace the speed sensor.
  • STEP 4: After removing the sensor from the hub, clean any dirt or debris that may have accumulated.
  • STEP 5: Install the new speed sensor.

Once you’ve replaced the sensor, you must clear the diagnostic trouble codes (DTCs) from the vehicle’s computer system (failure memory).

You can do this by using an OBD-II scanner or disconnecting the battery for a few minutes.

It’s important to note that if you’re not comfortable performing these steps yourself, you can seek the help of a qualified technician who can diagnose and repair the problem for you.

4. Problem with HUD Unit Screen Seal:

Honda Rincon 680 customers commonly report issues with the HUD unit screen seal, which allows water droplets to enter and disrupt its functioning. This issue often occurs due to the seal not working as expected.

Luckily, if you have a warranty for your Honda Rincon 680, you're probably covered and can get the necessary repair or replacement done for free. However, you may be responsible for the cost if you don't have a warranty.
10 Most Common Honda Rincon 680 Problems- How to Fix

How To Fix:

  • STEP 1: The first step is to inspect the seal to see any visible damage. If there is, you should replace the seal immediately.
  • STEP 2: If there isn’t, you’ll need to take a closer look. For example, the seal may be in good condition, but the area around it has become warped or distorted. If so, you must replace the seal and the frame around it.
  • STEP 3: It’s also possible that the seal is simply not tight enough. If this is the case, you must use a sealant or tape to ensure it fits properly. This should take care of the problem and keep the water out.

5. Unstable Brakes:

The hand brake of this vehicle is suitable for flat ground, but it is not as effective for mountain trails. This can be dangerous, as relying on the hand brake in these conditions is difficult.

Additionally, the Rincon 680 emergency brake doesn’t work often, and the regular brakes seem unreliable.

This is concerning, as the brakes are a crucial part of any vehicle. Without functioning brakes, the driver won’t be able to slow down or stop the vehicle on time.

This can lead to severe accidents, so it’s essential to ensure the brakes of the Honda Rincon 680 are functioning properly.

10 Most Common Honda Rincon 680 Problems- How to Fix
A brake problem has been reported recently by a Rincon 680 user. Upon inspection, it was discovered that the hand lever for the brakes was not functioning correctly, while the foot brake seemed to be working fine.

Despite adjustments to the cable nut, the hand brake remained unresponsive. The rider attempted to bleed the rear brake, but this did not resolve the issue. The hand lever does not transmit pressure to the brake pads effectively.

Several factors, including a damaged cable, a broken lever or caliper, or a malfunctioning hydraulic system, may cause this problem. Further diagnosis is required to determine the exact cause of the issue.

How To Fix:

If you are experiencing brake problems with your Honda Rincon 680, don’t worry! You can take a few steps to diagnose and fix the issue.

  • STEP 1: Check the brake pads and ensure they are not worn down beyond their service limit. If the pads are worn, replace them with new ones.
  • STEP 2: Inspect the brake caliper and ensure it is functioning correctly. The caliper should move freely, and the piston should not be seized or rusted. If necessary, replace the caliper.
  • STEP 3: Check the brake lever and cable if the issue persists. Ensure the lever is not damaged and the cable is not frayed or kinked. Adjust the cable tension if necessary.
  • STEP 4: If none of these steps resolve the problem, it may be an issue with the hydraulic system. Check the brake fluid level and ensure it is within the recommended range. If the fluid is low, refill it and check for leaks. If there are leaks, have them repaired.

If you are unsure how to perform any of these steps or suspect a more severe problem, it is recommended to seek professional assistance.

A qualified mechanic can diagnose and repair any issues with your Honda Rincon 680’s brakes, ensuring your ATV remains safe and reliable for all your off-road adventures.

6. Problem with Seats:

While most ATVs don’t require any adjustments to the seat, Honda Rincon 680 does. Unfortunately, this means that you have to adjust the seat latch for it to stay in place. This can be a nuisance for riders, especially when the seat latch doesn’t stay put.

This issue can become very hazardous for ATV riders, as it can cause them to lose their balance and fall off the ATV.

If you’ve ever been on a Honda Rincon 680, you know it’s hard to get in and out of the seat at first, and having to adjust the seat latch can make this process even more difficult.

How To Fix:

You can seek help from an expert or an ATV mechanic to fix the latch adjustments of the seats of your Rincon 680. If your vehicle has a warranty, it will cover such minor issues and there is no need to consult another mechanic rather than seek help from the manufacturers.

Adjusting the seat in your Honda Rincon 680 is a simple process that can significantly improve your riding comfort. Here’s how to do it:

  • STEP 1: Locate the seat release lever on the left side of the ATV, just below the seat.
  • STEP 2: Lift the lever to release the seat from the frame.
  • STEP 3: Push the seat forward to adjust its position.
  • STEP 4: Once you have positioned the seat where you want it, push down on the middle of the seat so the tabs on each side of the seat go underneath the metal tabs on the frame.
  • STEP 5: Look at the bottom of the seat to ensure that the plastic tabs are now riding on top of the metal tabs.
  • STEP 6: Push the seat down firmly until it latches into place.

Congratulations, you have successfully adjusted the seat in your Honda Rincon 680! Remember to test it before riding to ensure it is secure and comfortable.

7. Problem with Transmission of Vehicle:

Transmission problems can be a major headache for any vehicle owner, and the Honda Rincon 680 is no exception. In addition, as a rider, you may be experiencing gear shift problems with your Rincon 680, which can cause frustration.

The transmission of the Rincon 680 consists of a hydraulic torque converter, hydraulic clutches, and an ECM (Electronic Control Module Unit).

These components work together to shift gears when you move the gear selector. The ECM monitors the throttle’s opening, the vehicle’s speed, the gear selector’s position, and the engine oil temperature.

Various underlying issues cause the gear shift problems with the Rincon 680. These include poor transmission quality, wear and tear on the transmission components, and improper maintenance.

Poor maintenance of the transmission can include not changing the transmission fluid regularly or replacing worn parts. In addition, problems can arise from improper installation of the transmission components.

They can also recommend the best transmission fluid and other maintenance procedures needed to ensure the proper functioning of your transmission system.

8. Issue of Engine Smoke:

Engine smoke is an issue that has been plaguing the owners of Honda Rincon 680 vehicles for a long time. The smoke in the engine is a serious problem that can lead to costly repairs and an overall decrease in the vehicle’s performance.

The color of the smoke can be an indication of the type of problem that is present in the engine. For example, white smoke indicates a blown gasket, while black smoke means the engine is burning too much gasoline, which can lead to poor fuel economy. Blue or grayish smoke is usually a sign that the engine is burning oil, which can lead to further damage.

Several things, such as a lack of maintenance, a faulty fuel delivery system, or a worn-out engine part, can cause these issues. It is important to note that the color of the smoke can help diagnose the problem.

It is difficult to fix this issue at home, so it is better to consult a mechanic who can detect the root cause of this issue.

9. Presence of Faulty Seals in Vehicle:

The most common cause of faulty seals in the Rincon 680 is age. As the seals age, they become brittle and prone to cracking. In this case, the best action is to replace the old seals with new ones.

It is also essential to ensure that the sealant used to install the seals is high quality. If the sealant is not up to par, it could lead to further issues with the seals.

How To Fix:

The best way to ensure that your seals are in good condition is to inspect them regularly for signs of wear and tear.

If any signs of damage are seen, it is essential to replace the seal immediately. Not only will this help keep your vehicle running smoothly, but it can also be a matter of safety.
