Known by various names such as MINI Hatch and MINI Hardtop, MINI Cooper stuck to most people.

The original Mini Coopers range was made in 1961 and saw a run for ten years. It was brought back in 1990 for another ten years.

Why has the Mini Cooper had to distance itself from its previous, more well-established name? This might be due to the fact the car tends to come with a variety of issues.

Many of these issues will stop you in your track and make you ask, “Why won’t my Mini Cooper start?”.

It will be quite difficult to pinpoint the source of this problem, mainly because it could be in any of the crucial systems.

The ignition system, battery, and other components could have a defect preventing the car from turning on.

The most common of these problems include:

  1. Bad Starter
  2. Dead Battery
  3. Defective Alternator
  4. Fuel Issues
  5. Failing Ignition Switch

This article will help you figure out how to locate the problem in your Mini Cooper. It will also aid in educating you on the various problems you should expect from a Mini Cooper.

I will be going over all these topics in this article, so do take the time to read it.

What Would Cause A Mini Cooper To Not Start?

How to start your Mini Cooper if your vehicle won't start? Read my guide to learn how

Cars are very delicate on the inside. Even one minor issue can mess up the entire inner workings of the car.

For this reason, you should ensure that if you face the problems mentioned above, you get your Mini Cooper to the mechanic promptly.

In this section, I will go over these problems in detail.

1: Bad Starter

A bad starter can easily halt the ignition process of your vehicle. Since the starter controls specific parts, such as the flywheel, it must work properly.

A starter issue is not unheard of when it comes to Mini Coopers, and it is quite common for cars to face issues due to this component.

This is usually because the starter motor does not last for more than 5 to 6 years and can go up to 10 if you put in the maintenance.

Bad weather, a small lifetime, and low maintenance are easy-to-understand reasons why your starter may develop issues.

Additionally, if you have been facing oil leaks, corrosion, or any form of loose wiring, then it is also likely that you may have gotten a bad starter.

What Should You Do About It?

  • If you think your starter is broken, you will have to visit a mechanic to get repairs. The best way to do so is to jumpstart your car. This should enable you to temporarily start the car.
  • Once you reach the mechanic, you can repair or replace the starter. It is recommended to replace it as it will be cheaper to do that than replace it. This too, however, will cost you a pretty penny.
  • To avoid this issue in the future, you should try to keep the Mini Cooper away from damp environments and carry out regular maintenance to take care of corrosion and loose wires.

2: Dead Battery

The battery is an important part of any car as it allocates power to each component of the car. It is safe to say that without a proper and functional battery, no car can even hope to turn on.

This is why a lot of pressure comes on the battery performing well. Unfortunately, the battery is responsible for the most issues when it comes to starting the car.

Batteries are high maintenance, and they will lose their charge if you do not treat them right.

Leaving your Mini Cooper unintended for too long can result in the battery losing its charge. The same occurs when the car is left in the cold or if the alternator is having some issues.

What Should You Do About It?

  • Carry out a voltage test to see if the battery is why your Mini Cooper is unable to turn over. If your battery shows less than 12 volts, then it is the cause of your troubles.
  • If your battery is older than 4 to 5 years old, you can opt to get a replacement battery. Typical car batteries do not last more than 4 to 5 years, and replacing them is a good idea.
  • If your battery is new, then you can just have it jumpstarted.
  • To ensure this does not happen again, ensure the car is used frequently and kept in a safe place.

3: Defective Alternator

The alternator is another essential component to ensure that the battery operates at its full potential. The reason the alternator exists is to charge the battery.

It converts the mechanical energy from the engine to electrical energy, supplying it to the battery.

The battery does not charge by itself; without the alternator, it would die within a matter of hours at most.

Since the issue affects the battery directly, many people jump to the wrong conclusion. They suspect the battery is to blame and get it jumpstarted or replaced.

What Should You Do About It?

  • Create a timeline and see how long your battery lasts after a jumpstart. Your alternator is to blame if it is less than a day.
  • Check for physical signs of damage on the alternator. Do not try to open up or disassemble the alternator unless you know what you are doing.
  • At this point, you should visit a mechanic and have it checked out.
  • It is much more economical to have it fixed rather than repaired and will also spare you some issues in the future.
  • Once you have a working alternator, make sure you give it the attention it needs and avoid things like overheating it.

4: Fuel Issues

While this may sound like a no-brainer, your Mini Cooper needs fuel to run. It is easy to forget to fill up your gas tank while enjoying the Mini Cooper’s impressive drive.

It could be likely that you simply do not have enough fuel and need to visit your local gas station.

If you get your tank filled and still have issues, you might have a few obstacles preventing your fuel from reaching the engine.

A weak fuel pump may be responsible for pumping less fuel into the engine, preventing it from turning on.

Additionally, you may have blockages or leaks, which may further hamper any fuel from reaching the engine.

All of this can be avoided with ample maintenance, but if you find yourself in this position, this next section should do you some good.

What Should You Do About It?

  • Check your fuel gauge and see if you have enough fuel. If you think your fuel gauge is defective, manually check the tank and see if it is out of fuel.
  • If your fuel pump does not provide enough fuel to the engine, you will have to fix or replace it.
  • I would recommend that you get a new one to avoid the issues that come with having to fix an old fuel pump.
  • Check for leaks. If you find any, then make sure to plug them up properly to avoid fuel wastage.
  • Replace the fuel filters 1 to 2 times a year to avoid blockages. Additionally, use quality fuel to prevent further blockages.

5: Failing Ignition Switch

One cannot hope to even start their car if the ignition switch is showing any sort of faults or issues.

While turning on your Mini Cooper with a faulty or failing ignition switch is possible, it will be accompanied by various issues.

These issues include stalling, power loss, difficulties turning the key, and eventually, the engine not starting.

This is usually caused by the contacts of the ignition switch wearing out. Alternatively, you could have a defective spring which could be the issue’s root.

Other causes include temperature problems and rough usage of the switch itself. This is likely due to the mishandling of the keys.

Here is what you should do if you have a failing ignition switch.

What Should You Do About It?

  • Since the ignition switch is likely too complex for you, it is recommended that you take your Mini Cooper to a mechanic.
  • Have the mechanic check the switch out and carry out the necessary fix.
  • You may also have to replace the switch if it is too worn out.
  • To ensure this does not happen in the future, you must avoid rough usage of the switch by using the key as gently as possible.

Q6. Why Won’t My Mini Cooper Start In The Cold Weather?

Staying in the cold weather for too wrong can wreak havoc on a car. It starts by preventing your spark plugs from doing their job.

The battery shows a drop in output, and the oil also starts to thicken up. All this adds up quickly to prevent the car from starting at all.

Q7. Why Won’t My Mini Cooper Start After I Get Gas?

You may have gotten gas, but that is no guarantee that it is reaching the engine of the Mini Cooper. You may be dealing with some sort of blockage or leakage.

Check for any leaks and patch them up as soon as possible. You should also replace your fuel filters while you’re at it.

Q8. Why Won’t My Mini Cooper Start But Radio Works?

Your Mini Cooper’s radio system also relies on a low amount of power to turn on. If it can turn on, not the engine, your battery is out of charge.
