Mitsubishi Routine Maintenance Required: Causes and Fixes

“Mitsubishi Routine Maintenance Required” is a warning message that appears on your dashboard as a reminder that maintenance is due. Your maintenance routine will depend on the vehicle model, the periods between past maintenance, mileage driven, and any other maintenance requirements proscribed by Manufacturers.

Routine maintenance, such as oil changes, tire rotations, brake inspections, fluid checks etc, can also increase the longevity of components of your vehicle. Ignoring this can lead to your vehicle developing issues down the road and can also affect the vehicle’s warranty.

In this article, we will focus on the causes of the Mitsubishi Routine Maintenance Required and how you can fix them.

What is Mitsubishi Routine Maintenance Required?

Mitsubishi Routine maintenance required is a service message indicating the need for Mitsubishi drivers or owners to carry out scheduled maintenance on their vehicles. 

This message is displayed on the dashboard by a wrench-like figure above Mitsubushi’s routine maintenance required. It serves as a reminder that the timeframe for routine maintenance has been exceeded. 

Generally, all Mitsubishi Manufacturers include a recommended timeframe for maintenance in their manual. This time frame is divided and classified to match the estimated maintenance period of every component in the vehicle.

For example, every three (3) months or 3750 miles, it is recommended that you change your engine oil, oil filter and inspect the cabin air filter. However, you need to replace the oil filter, and the cabin air filter and check the suspension system, disc brake pads, rotors, etc., every six (6) months or 7,500 miles. Finally, your spark plugs, air filter, and oil filter will need replacement every twelve (12) months or 15,000 miles.

Your Mitsubishi pays a harsh price if you do not carry out routine maintenance. And depending on how the affected vehicle component reacts, the consequence may be mild, costly, and fatal (in cases of accidents).

Causes of Mitsubishi Routine Maintenance Required

Mitsubishi routine maintenance required is caused by faults your vehicle develops due to a lack of routine maintenance.

Below are some causes of this problem:

Engine Oil-related Issues

Routine maintenance ensures that your engine oil stays fresh with all the necessary viscosity for optimal performance. 

When you skip routine maintenance, your engine oil loses its substance. As such, your vehicle may suffer from low engine oil, oil leaks, sludge build-up, etc. 

Routine maintenance has exceeded a specific timeframe.

Generally, vehicle owners are recommended to carry out regular maintenance around specific periods. This is usually within three (3) months, six (6) months, nine (9) months, and 12 months. Drivers are expected to take on tasks like replacing oil. Oil filters, inspect brake discs, pads, and your suspension system. 

If time passes without you carrying out maintenance, the routine maintenance required message is triggered.

Routine maintenance has exceeded specific miles.

There are several maintenance tasks that are gauged based on miles traveled. 

Engine oil, for instance, would need to be changed every 3,000 – 5,000 miles for conventional oil and every 7,500 – 10,000 miles for synthetic oil. 

Also, you may need to rotate tires every 5,000 to 7,500 miles, Check the suspension system every 7,500 miles, and replace spark plugs every 15,000 miles. The reminder message will be activated when your vehicle drives past designated miles without the relevant maintenance.

Sensory data

Different sensors around your vehicle analyze sensory data. These sensors collect data on fluid levels, engine condition, wear, etc. Depending on the type of data retrieved, a routine maintenance required message may come up.

The message is not reset properly 

When routine maintenance is duly performed, the reminder is expected to be manually reset by the person who carried out the maintenance. 

If the reminder is not reset or if it was improperly reset, the routine maintenance required message will continue to display on your dashboard. It is important to note that a routine maintenance required message on your dashboard does not stop you from driving. It, however, serves as a reminder that your routine maintenance is due.

Fixes for Mitsubishi Routine Maintenance Required

Although this might sound cliche, the only way to resolve the routine maintenance required message is to carry out routine maintenance on your vehicle. Abiding by your manual, each maintenance bout should be either time-bound or mileage-bound.
