  • Engine Mitsubishi Galant Problems 

The Mitsubishi Galant’s first engine problem is the excessive oil consumption, with the average occurrence happening at around 165,000 miles. The oil consumption is very common in this model year, meaning that owners may need to check their oil every time you pump the gas, so the oil leak does not cause engine seizing and shaking during use. 


The second problem is the oil leaking, with the occurrence happening at around 48,000 miles. Owners state that the oil leaks after prolonged use of having a car, and the car must be brought into a mechanic to deal with the oil leak before it gets any worse. 

Engine Oil Importance 

Engine oil is a crucial part of your vehicle – if you do not replace your oil or have healthy liquid, this can cause the Mitsubishi Galant problems. Engine oil needs to provide proper lubrication for the internal engine parts susceptible to overheating, excess friction, and rubbing against each other during use. 


Without the engine oil, metal-on-metal contact would damage your engine to the point of no return very shortly, leading to an expensive and extensive replacement. The second main reason why engine oil is vital for your vehicle is cooling the parts due to overheating. The last reason why engine oil is essential in your car is to clean the engine and prevent any buildup of debris, dirt, and contaminants.

Radiator Flush

To keep the radiator working at a high level and prevent any future Mitsubishi Galant problems, you may need to perform a radiator flush to keep the cooling system operating at an efficient level. 


A coolant flush can resolve the problem of the debris build-up. The flush is a change of liquids that are being circulated throughout your cooling system, with the flush forcing several gallons of cleaner and new antifreeze through the radiator system to get rid of the old antifreeze the contaminants that may have built up and caused a lack of performance in the radiator system. 


Draining the radiator might get rid of most of the antifreeze that has accumulated, but it could also leave some coolants and debris behind that can cause performance issues. The contaminants left behind after the radiator flush can mix with your new antifreeze and cause overheating and friction creation. To get a full flush, you need to remove all unwanted debris and the old liquid so that the old antifreeze does not mix with the newer antifreeze.

  • Exhaust System Mitsubishi Galant Problems

The man problem within the exhaust system for this make and car model is that the catalytic converter stops working. To replace the catalytic converter, you have to pay around $2,000 to repair around 100,000 miles.

Owners stated that the front brake rotors’ premature failure, with the issues constantly recurring and needing consistent fixing. The front brakes also chatter while braking, causing an increased braking distance and a significantly reduced braking power. 

Uneven Brake Pad Wear

A further Mitsubishi Galant problem that you need to deal with as an owner of this make and model is uneven brake pad wear. Brake pads are a crucial part of the system because they contact and apply pressure and the necessary friction to a vehicle’s brake rotors. The brake rotors clamp down to stop the wheels from spinning. Brake rotors are just as important as brake pads in the braking function. The average cost of rotor pad replacement ranges from $406-$559. 


There are certain signs in your Mitsubishi Galant that it is time to replace your brakes, brake pads, or brake rotors to ensure you drive safely. 

Screeching Noises

A screeching sound is caused by a small indicator that’s placed in your brake pad for this purpose specifically. If you hear this while braking, it’s time to take your car in for inspection. In addition, if your brakes are constantly exposed to wet or damp conditions, then a layer of dust can form on the brake pads, causing a screeching sound while you brake. 

Grinding When Braking

There might be a loud grinding while braking. If you hear a deep and low noise, this is typically a sign that the brake pads wear away and that your brake discs and calipers are currently rubbing against each other. This rubbing can be due to the uneven brake pad wear over time. 

Increased Stopping Time

Third, it might take longer for your car to come to a complete stop since the brake pads are wearing down. Fourth, you might feel pulsations and vibrations coming through the brake pedal. Also, the brake pedal might physically move closer to the floor. 

Indicator Light

Lastly, your vehicle might have an indicator light that will come on to signal when it is time to replace your brake pads. If your light comes on, you’ll have to bring your car to a mechanic to shut off the light, as well as check the brake pads. Noticing these signs gives you an indication as to when your brake pads should be replaced for optimal performance.
