What Mileage Do Cars Start Having Problems?

Car's mileage milestones

You recently bought your first new car and now want to make the best of it. Eager to go on all the long drives you had planned, you are also curious to know about the car’s mileage milestones. 

Before knocking out your car miles, it’s a good idea to know about the performance of your car and at what mileage do cars start having problems. This way, you can prepare for the situations that might arise. 

So, let’s dive right in and find out what car mileage means for your vehicle.

What is Considered High Mileage

12k to 15k miles on a car each year are considered normal for many situations. If you drive a vehicle over this mileage, then it is categorized as a high mileage vehicle. With proper maintenance and care, a car can easily have a life expectancy of about 200k miles.

However, by that, you can’t just say that after three years or ten years, your vehicle will become the end of life. 

What To Expect At 50,000 Miles

At 50k miles, the risk of the car components giving a hard time increases. Here is what you can expect at 50,000 mileage on your car:

Brake Pads: These are an important safety feature of a car, so applying unusually high pressure to stop or slow down can cause them to wear. You might feel excessive or grinding noise because of worn brake pads. 

Tyres: Always get the suspension and steering checked by a professional for uneven or significant wear amount on the tyres. If you initially fit the car tyres to the budget or got partly worn tyres, we strongly recommend changing them, especially after 60,000 miles.

As eager as you are to go on all the long drives you had planned, you are also curious about your car’s mileage milestones.

What To Expect At 100,000 Miles

If you don’t plan on keeping a car beyond 100k miles, we provide a free old car collection. Here is what you can expect at 100,000 mileage on your car:

O2 Sensors: Reaching 120k miles means you have nearly burned 5000 gallons of fuel. So, the byproducts collect in the O2 sensors, which means the fuel mixing response becomes slower.

Spark Plugs: The spark plasma gets worn every time electrodes light the spark plug. The increasing gap means firing the spark plug needs more energy, ultimately affecting the coils.

A / C compressor clutch: The A/C compressor may wear with time and start slipping. A thorough inspection procedure can determine if the clutch needs repair.

Coolant: After 100k miles, the coolant may not lose the heat transfer ability, but it surely loses in controlling the coolant’s pH level and corrosion. 

Decoupler-Pulleys: Some pulleys wear down even in 60k miles. But after 100k miles, these pulleys reduce vibration and drop efficiency. Failure to change them can cause issues like weak batteries, slow charging, and bad fuel economy.

Shocks & Struts: Replacing shock and struts after 50k miles is highly recommended. Usually, a shock and strut hit around 1750 times per mile, which is why replacement is important. 

Belt Tensioner: It’s good to replace the belt tensioner if the vehicle has made it this far. Regular service is also crucial. 

Fuel Chamber: Carbon deposit on the head, valves, and piston crown can cause hot spots, increased compression ratio, and chamber turbulence. Remove these deposits using engine-de-carbonization.

MAF Sensor: After 1,50,000 miles, car engines start consuming a really high amount. The MAF (mass airflow) sensor becomes contaminated even with the filter present. Cleaning the filter can increase fuel economy and performance.

Drivetrain Seals: A regular inspection of seals on driveshafts and axles are very important. A leaking drivetrain seal causes fluid loss but not a breakdown. Still, we recommend a quick replacement as soon as you find a leakage. This way, you can save expensive components. 

Steering Fluid: The power steering fluid has anti-foaming and anti-corrosion additives that start breaking with time, increasing wear and tear. 

Engine & transmission mounts: A worn transmission mount can cause serious engine issues, and ignoring it can cause cable displacement and exhaust system leakage. 

Timing Chains: When exposed to the engine oil and heat cycles, the timing belt becomes brittle. They wear over time and start leaking. A very usual timing chain tensioner failure sign is timing skips, noise, and engine light. 

What To Expect at 200,000 Miles

200k is quite high mileage for a car. If your vehicle has reached this mileage, you must have taken good care of it throughout. 

After you get 200k miles, you can expect the following:

  • Fuel injector problems
  • Catalytic converter failure
  • Bad chassis health
  • Debris between the condenser and the radiator

We also offer scrap car removal for cars over 200,000 and 300,000 miles without needing you to do any major repairs. 

Is Mileage More Important Or Age

Sometimes you come across offers that don’t make any sense. For example, a car with more age is priced higher than one with less age. So, how is it possible? 

That’s because the number of miles on a car directly affects its condition. After thousands of miles, a car needs parts replacement. But if the parts are in good condition, the age doesn’t really matter. 

If you are looking to sell your high mileage car and get cash for cars Brisbane, we are ready to buy it. 


Wondering about your car’s mileage milestones? This blog guides you from the moment mileage on the car starts until it becomes too high. 

We recommend you get your car regularly serviced by a professional mechanic and keep an eye on car components. If your car’s repair and maintenance start costing you more than its value, National Car Removal is at your service.
