Nobody wants to be faced with unexpected car repairs, but there are some fixes that you can do yourself without involving a mechanic. There are some minor mechanical defects that are simple and inexpensive to fix. Here’s a breakdown of eight common problems that can be resolved for under $50 and why you might find yourself paying more at a shop.
1. Headlight Bulb Replacement – A Simple Fix Marked Up

Replacing a headlight bulb in your car is one of the easiest repairs you can DIY. It often only requires popping the hood and unscrewing the old bulb. Depending on your car, each bulb likely costs between $10 and $20. Heading to the mechanic for this problem could easily cost more than $50 though and if you go to a dealership, it could be even more expensive. This is because they markup the labor for this task substantially.
2. Air Filter Replacement – DIY for Less

Once again, depending on your vehicle, you can usually get an air filter for $20 or less. It only takes a few minutes to replace it. Most modern cars make it pretty easy to pop open the air filter housing and remove the old filter. Then, you just drop in the new one. You might be surprised to discover that such an easy fix often costs $50+ at a mechanic’s shop. You’re paying for labor costs and a bit of a convenience fee since it’s something you really could do yourself.
3. Windshield Wiper Blade Replacement – The Quick Fix Overcharged

Windshield wipers are another easy fix that people frequently pay too much for at the shop. A set of wiper blades might cost between $15 and $30, depending on the make and model of the car. You’ll spend about five minutes replacing the blades and then you are good to go. Shops, on the other hand, will often charge you double or triple, quoting labor fees as the reason to drive the price up.
4. Battery Terminal Cleaning – Simple Cleaning for Pennies

Corroded battery terminals can start causing problems with the electrics in your car. Cleaning them off is incredibly cheap and easy. You just need a wire brush, baking soda, and water to get the job done. Overall, you’ll spend less than $5. You might find a shop charges you $50+ to perform this task, despite it being painfully easy. They’ll mask the overall cost with labor fees when it actually only takes a few minutes.
5. Fuses – $5 Fix, but Often Overpriced

A blown fuse can cause a number of issues, but they are incredibly cheap and easy to fix. Each fuse is probably only about $5 each and replacing them takes just a few minutes. You’ll just need to locate the fuse box and pop in a new one. Of course, many shops will mark up the cost of fuses and charge you for unrealistic labor times for this simple task.
6. Tire Patch – Inexpensive and Quick, But Priced High

You should always have a tire repair kit in your car. A small puncture can usually be addressed for less than $10, but a shop will charge you between $20 and $50 for a patch. Not to mention, the shop will try to upsell you a new tire, which could mean you spending unnecessary money. Patching is an easy job that most tire shops can do quickly and cheaply, but they mark up labor to make money off you.
7. Spark Plug Replacement – Inexpensive Parts, Labor Marked Up

Spark plugs are another incredibly easy fix that shops like to mark up. They’re usually under $10 each and the job is straightforward. Depending on the vehicle, this job can take some time, but shops tend to charge high labor fees for the job. In some cases, a spark plug job might cost $100 or more. With a little guidance, this is a repair that can be done at home for a fraction of the price.
8. Cabin Air Filter – Easy Swap Priced High

Cabin air filters play a crucial role in ensuring that the air that enters the interior of your car is clean. Like the engine air filter, it is easy to replace. You’ll find that most filters cost between $15 and $30, depending on the car. All you have to do is open the compartment and replace the filter. Some mechanics will charge as much as $70 for the convenience of them doing it for you.
Why Are You Paying More?

The main reason many of these repairs cost so much at a shop is due to labor and overhead costs. Auto repair shops have to be able to cover what they need, from paying their staff to keeping the lights on. So, oftentimes, even the simplest of repairs come with higher labor fees. Many consumers aren’t aware of how simple some of these fixes can be and they wind up spending more for professional help.
