Best Online Mechanics Courses 

by Charlie Saville

When you buy through links on our site, we may earn a commission at no extra cost to you. However, this does not influence our evaluations.

Over 278,00,000 vehicles are registered to drivers in the US. And they could all run into trouble at some point. As cars continue to dominate the way we travel, more and more people are learning how to be a mechanic online to break into this essential industry. 

But a search for the best online mechanic course online returns 147,000,000 results. So can you find the best mechanic course for you?

I think the answer is yes. And to prove it I’ve written this article containing what I believe to be the best online mechanic courses. 

In my opinion, the best pick is Car Mechanic Training from Alison education. This class provides a great introduction to the world of cars and how to repair them, with three hours of content covering all of the essentials. And to top it all off, it's free. 

However, I’ve tried to include a range of courses here. Half are aimed at casual car drivers looking to learn more about how to repair their vehicle, and the other half aimed at aspiring mechanics looking for their first professional qualifications.  

We’ll be taking a deep look at each course's content, strengths, weaknesses, and much more. I’ll also talk about the benefits of an online mechanic course, the average length, the cost and a buyer’s guide on what to look out for.

  8. Automotive ownership maintenance (Udemy) 
  9. Car mechanic and car maintenance level 3 diploma (Training Express) 
  10. Car mechanic and repair training (Apex Learning)

I’ve chosen Car Mechanic Training for my top pick for a couple of reasons. With over 70,000 students enrolled, it is one of the most popular courses on this list, offering to teach students how to master all the key components of car maintenance. 

For me, this is the go-to course for any absolute beginners who are looking to take their first steps with automobile mechanics. Why? It packs a bunch of info into just 3 hours, managing to be both hugely informative to new learners and not daunting. It is also free!

Udemy is the site with the most appearances on this list. This is because it's focused on selling individual courses to help with specific skills. Often at a discounted price!

Each Udemy mechanic course has a slightly different focus. Automotive 101: A beginners guide to car repair is the most popular, well-reviewed and, in my opinion, Udemy’s best offering. 

Finally, if you’re looking for something really in-depth, that will kickstart your journey to becoming a professional mechanic, check out Car Mechanic Training: Car detailing, car maintenance & car restoration [CPD certified] from One Education.  It has over a week of content, and a Continuing Professional Development-accredited certificate available upon completion of a final exam.

You don’t need any prior experience, yet this course will plunge you into learning about the systems and components of an automobile. And how and why they require maintenance. It's not formal training to become a mechanic, but is a first step towards that-or just a way for the average person to learn more about maintaining their car.

However, this course is packed with a bit more of a technical focus, with coverage of the rear differential, driveshaft and other terms that might mean nothing to you. If you're more serious about automobile mechanics, this might be the better option.

6. Car Mechanic and Repair Level 3 Diploma – CPD Accredited (Apex Learning)

Car mechanic diploma

Platform: Apex Learning | Teachers: Apex Learning | Course length: 11 hours 

This is the first of two courses from Apex Learning to appear on the list. With over 11 hours of content, it's twice as long as its sister course, so it is another good pick for anyone who's a little more serious about getting into car mechanics. 

Modules here cover everything from safety and maintenance to vehicle restoration. There is a specific emphasis on modern car systems. 

So, like Car Mechanic Training: Car detailing, car maintenance & car restoration from One Education, this one is worth considering if you think being a professional mechanic might be for you.

7. Car maintenance anyone can do (Udemy)

car maintenance for everyone udemy

Platform: Udemy | Teachers: Barry Bertollini | Course length: 3 hours 

As you can probably tell from the title, Car maintenance anyone can do from Udemy is for more casual learners. 

With three hours of learning, it is one of the shorter options on the list, but it's still packed with information. You will become fully aware of all the absolute essentials, including checking and fixing flats, maintaining fluids, battery levels and more. 

Your instructor, Barry Bertollini, has worked in the automobile industry for over 23 years and now works as a school teacher, so he encompasses the best of both worlds for mechanic education. He has taught over 3,000 students and has a 4.8-star instructor rating.

The instructor is super experienced and explains everything very clearly, and with a 4.8 star rating this is one of the best-reviewed options on the list. 

8. Automotive ownership maintenance (Udemy)

automotive maintenance course

Platform: Udemy | Teachers: Scott Greene | Course length: 2 hours 

The main difference between this and Automotive 101 (number two) is that it is focused mainly on those who are just casual car owners interested in learning more about their vehicle rather than aspiring mechanics.

As a result, it is about an hour shorter. However, it has also been updated more recently, so this is worth considering. Automotive Ownership Maintenance has a 4.7-star rating. 

You will learn how to:

  • Appreciate what (and what not) to wear when repairing your car

  • Created more recently than Automotive 101: A beginners guide to car repair

  • Similar material is covered more comprehensively in Automotive 101: A beginners guide to car repair
  • Closed captions don’t always align with what is being said on screen  

Best for: Car owners and drivers who want to learn the essentials of maintaining their vehicles 

Overall: Scott Greene is the only instructor to appear on this list twice, and it's easy to see why. With three decades of experience in car maintenance and having taught over 12,000 students on Udemy, he is the ideal teacher for this topic. I’d recommend this course for those who are interested in Scott’s content but are less intrigued by the prospect of becoming a full mechanic. 

9. Car mechanic and car maintenance level 3 diploma (Training Express)

10. Car mechanic and repair training (Apex Learning)

online car mechanic and repair training

Platform: Apex Learning | Teachers: Apex Learning | Course length: 4 hours and 45 minutes

Rounding off the list we have the second option from Apex Learning. 

I’ve included this course because I feel it sums up the point I’ve been trying to make throughout this article quite nicely; there are a range of car mechanic courses out there but really they can be divided into two groups. 

There are classes for people considering becoming a professional mechanic and there are classes for those who just want to learn a bit more about how to fix their car. 

At under half the length of the other Apex Learning course, Car mechanic and repair training is Apex’s attempt to tailor to the latter group. 

What you will learn:

  • Safety rules 
  • Introduction to tools
  • General maintenance 
  • Dashboard indicator lights 
  • Tires
  • Internal combustion engines 
  • Engine oils

  • Electrical system 
  • Drive train 
  • Brakes 
  • Buying a car 


  • Offers a very brief introduction for absolute beginners 
  • Systemically covers all of the essentials 
  • Very easy to follow 
  • Includes an assignment 
  • Can be studied at your own pace 


  • Not massively comprehensive 
  • Covers very similar content to other courses on this list  

Best for: Anyone interested in Apex’s first course who felt it was a little too long 

Overall: With almost 5 hours of learning, Car mechanic and repair training will equip you with all the essentials you need to get started with repairing your car. Although I feel this course is better suited to casual learners, if you enjoy it you might consider checking out Apex’s other courses or just going straight to in-person training. 

What are the advantages of taking an online mechanic course?

online mechanic courses advantages

There are many advantages to taking one of the courses on this list:

  • The chance to take a first step towards a lifetime career 
  • Learn more about your own vehicle, which could save time, effort and money
  • Improve your safety when driving by knowing what faults and problems to look out for 
  • Gain a professionally-accredited certification 
  • Help out friends and family with their own car troubles 
  • Learn more and develop your intuition about systems and vehicles generally through practical examples 

There are also specific benefits to taking a mechanic course online: 

  • Access to top instructors from around the world with years of experience in the motor industry 
  • You can learn when you like and fit everything around your schedule 
  • You can combine different platforms for example, taking a One Education course to gain a certification and supplementing it with free Alison lessons

  • The skill will stay with you for life 
  • Your general knowledge about cars will improve 
  • Learning a new skill is great for engaging the brain

Buyers guide: what to look out for

car jack stand

There is clearly a wide range of mechanic courses out there. So here’s a helpful buyer’s guide to look out for: 

  • Positive reviews and feedback from both users and sites like Learnopoly 
  • The credentials of the instructor e.g. are they a professional mechanic? How long have they been teaching?  
  • How long the course is and what parts of the car each lesson will teach you about 
  • Any additional materials like safety manuals 
  • What kind of vehicle does the course focus on 
  • How many people are enrolled 
  • Is there any free trial or refund available? 

How much does it cost?

online car mechanic course cost

The costs of courses here range from free to $424.99. There are a couple of things worth noting about this. 

All of the options I have selected frequently have classes on sale. This means that you can get courses at a heavily discounted price and it is very rare for these lessons to only be available at these higher prices. 

For example, $424.99 is the price of Car Mechanic Training: Car detailing, car maintenance & car restoration [CPD certified] from One Education. However, when I was researching and testing the course it was on sale for $29.00. 

You might think that it is not worth paying these prices anyway, especially as there are classes on being a mechanic on places like YouTube which you can access for free. 

I would agree that paying for these kinds of lessons might not be worth it for casual learners. However, if you are serious about improving your skills, having a course where everything is organized and structured in one place to develop your learning is really helpful. 

Also, many of these classes include a certificate of completion, some of which are professionally accredited. This can make a world of difference for those who are serious about entering the profession. 

How long does it take to learn how to repair your car?

car mechanic course

Courses here last between two hours and one week. However, that doesn’t mean it will take you this long to learn how to fix your car. 

Cars are very complex vehicles and all kinds of things can go wrong with them. And all cars are very different. This list contains beginner courses on automobile repairs, but no option on here claims to cover each and every aspect of car mechanics.  

What these lessons do provide is the absolutely essential fundamentals of understanding the systems and parts that make-up your vehicle. 

If you are looking to become a mechanic, or to really advance your knowledge of cars and how they function, some in-person training and experience will be required. But every option on this list will be an excellent starting point. 


My top pick is Car Mechanic Training offered by Alison. 

This course is the most popular on this list, with over 70,000 enrollments. It's three hours long, which is ideal for a beginner course and it's totally free. 

However, the main reason I picked it is because of the comprehensive focus on key systems and components of a car. As well as its attention to the costs and considerations of car maintenance, makes it ideal for absolute beginners who want to learn more about how to fix any problems with their car. 

Another good pick is Automotive 101: A beginners guide to car repair from Udemy. This is also a three-hour course aimed at beginners but includes a bit more of a focus on technical language and components of the car. 

If you are a total newbie to car maintenance but are also quite interested in becoming a full mechanic, this could be a better option. 

Finally, there is Car Mechanic Training: Car detailing, car maintenance & car restoration, from One Education, for those who are a little more serious about taking on the role of a mechanic. This course includes a final exam and a CPD-accredited certificate of completion. 

As I mentioned in the cost section, a lot of the content on this list can be found elsewhere for free. So what you’re really investing in is a structured programme available all in one place and a certification to show what you have learnt. 

Most courses on this list are also on sale, so you do often get really good value for money. Make sure to look at the course page of the ones that appeal to you to check their most recent prices and watch any free material. Good luck!
