Vehicle inspection checklist
9 minute read Published on Sep 19, 2025 by BrokerLink Communications
If you drive, then you should know the importance of keeping your vehicle in tip-top shape. You rely on your car to get you from point A to point B. Thus, there’s nothing worse than an unexpected breakdown.
According to the Car Care Council, more than 70% of cars on the road have at least one unresolved issue that could lead to a breakdown. That means the odds are pretty high that your car might be overdue for some TLC. Thankfully, there are ways to ensure the longevity of your car, and that’s through regular maintenance and inspections.
Why vehicle inspections matter
According to AAA, 35% of car owners put off maintenance because of the cost. Ironically, that decision often leads to even pricier repairs down the road. AAA also said that the average unexpected vehicle repair cost is $500–$600 per incident. Regular check-ups, like inspecting the engine, topping off fluids, and replacing worn-out parts, can help you avoid costly repairs later on.
But keeping up with basic car maintenance isn’t just about avoiding breakdowns; it’s also about making sure your ride stays safe, reliable, and running smoothly for years to come. A little routine care now means fewer breakdowns, lower expenses, and a car that stays on the road (instead of in the shop) for years to come. And let's not forget that a well-maintained car runs more efficiently, saving you money on gas and reducing your impact on the environment.
How often should you check in on your car’s health?
A good rule of thumb is to inspect key components, like tire pressure, oil levels, and lights, at least once a month. More in-depth maintenance, like oil changes and brake checks, should follow your manufacturer’s recommended schedule, usually every few thousand miles. And don’t forget about an annual professional inspection to catch any hidden issues before they turn into bigger problems.
What tools will you need for a DIY vehicle inspection?
Before you dive into a DIY vehicle inspection, it’s a good idea to have the right tools on hand, such as:

Every vehicle has its own specific maintenance schedules, recommended fluid types, and unique inspection points. Following the manufacturer’s guidelines ensures you're checking everything properly and not overlooking something important.
Vehicle inspection checklist: exterior
Let's start with a visual inspection of the external components of your vehicle:
Safety lights
Your vehicle's safety lights include:
ul class="custom-col-list custom-col-lg-2 custom-col-md-1 custom-col-sm-1">Checking your lights is quick and easy. Just put your car in park, then turn on each light one at a time while you (or a friend) walk around the car to make sure everything is working. If you’re alone, you can check some lights, like brake lights, by backing up near a reflective surface, like a garage door or window, and watching for the reflection.
Windshield wipers
If your windshield wiper blades aren’t doing their job (leaving streaks, skipping across the glass, or just not clearing the rain like they used to), it’s probably time for a new set. When replacing them, make sure to get the right size and blade type for your car. Using the wrong size can lead to poor contact with the windshield, leaving you with annoying blind spots. Check your owner’s manual or use an online tool at an auto parts store to find the right fit.
Tires
Start by checking the tread depth. According to the National Highway Traffic Safety Administration (NHTSA), if your tire tread is less than 2/32 of an inch, it’s not just worn out—it’s legally unsafe. Bald tires take much longer to stop in wet conditions, making it harder to avoid accidents. You should have at least 3/16 of an inch of tread left. If it’s down to 1/8 of an inch or less, it’s time for new tires.
Tire pressure is just as important. Underinflated or overinflated tires can mess with handling, fuel efficiency, and even safety. In fact, according to the U.S. Department of Energy, driving on underinflated tires increases the risk of a tire blowout by 25%. Check the sticker inside the driver’s doorjamb for the recommended pressure, or look it up in your owner’s manual. A tire pressure gauge makes it easy to check levels before and after adding air. Also, don't forget to check the tire pressure on your spare tire so that it's ready to go if you ever need it.
Car inspection checklist: under the hood
Now, let's take a look under the hood:
Fluid levels
Small fluid leaks can go unnoticed, and fluids naturally get used up over time, so it’s important to check them regularly. According to CarMD, low or dirty engine oil is responsible for 44% of engine failures, and the Radiator Association of America says contaminated coolant leads to 40% of engine failures. Different cars have different ways to check fluids, so your owner’s manual is your best guide. But in most cases, you’ll find either a dipstick or a clear reservoir for checking levels. These will help you see your:
- Engine oil
- Engine coolant
- Power steering fluid
- Transmission fluid
- Brake fluid
- Windshield washer fluid
Battery
Corrosion (that crusty white or bluish buildup on the terminals) can interfere with the battery’s connection and make it harder for your car to start. If you notice corrosion, you can clean it off with a mixture of baking soda and water, but if it keeps coming back, it might be a sign of a bigger issue. Most car batteries last about 3-5 years.
Air filter
Over time, your air filter collects dirt, dust, and debris, which can clog it up and restrict airflow. According to the Environmental Protection Agency (EPA), a dirty air filter can decrease fuel efficiency by up to 10% while also increasing emissions. Most manufacturers recommend changing it once a year or every 20,000 kilometres. If you notice reduced fuel efficiency, sluggish acceleration, or a musty smell inside your car, your air filter might be overdue for a change. A quick visual check can also tell you a lot. If it looks dark, clogged, or covered in grime, it’s time for a replacement.
Vehicle inspection checklist: interior and safety features
Finally, let's move on to inspecting the vehicle's interior and safety features below:
Dashboard warning lights
Your dashboard warning lights are like your car’s way of talking to you. And here's why:
- A check engine light could mean anything from a loose gas cap to a serious engine problem, so start by tightening the cap and scanning for error codes with an OBD-II scanner.
- A battery light might mean your alternator isn’t charging properly.
- If you see an oil or temperature warning, pull over immediately to avoid engine damage.
- If the tire pressure light is on, check your air levels.
Seatbelts and airbags
To inspect your seatbelts, look for fraying, cuts, or weakened stitching on the seatbelt strap, and make sure it latches securely without sticking. Give it a firm tug to see if it locks properly. For airbags, check your dashboard for warning lights. If the airbag light stays on, there could be a problem with the system.
Brakes and pedals
When you press the brake pedal, it should feel firm, not spongy or soft. If it takes longer to stop or the pedal sinks too low, there could be a brake fluid or pad issue. Listen for squeaking, grinding, or vibrations, as these are signs your brake pads or rotors might be worn out. If the car pulls to one side when braking, that’s another red flag. Also, don't forget to test your parking brake. You can do this by engaging it on a slight incline—it should hold your car firmly in place.
Taking your vehicle for an inspection test drive
A quick test drive can tell you a lot about your car’s health as long as you know what to look (and listen) for. Start by paying attention to how your car feels when you accelerate, brake, and steer. Does it respond smoothly, or does something feel off?
Listen for unusual noises like squealing, grinding or clunking. A high-pitched squeal could mean your brake pads are wearing down, while a knocking sound from the engine might signal a more serious issue. If you hear a clicking or popping noise when turning, your suspension or CV joints might need attention. As you drive, check for these common issues:
| Issue | What it could mean |
|---|---|
| Sluggish acceleration | Could mean a clogged air filter, fuel system issue, or worn spark plugs. |
| Rough shifting | If your car jerks between gears, your transmission fluid might be low or your transmission could need servicing. |
| Steering feels loose or the steering wheel pulls to one side | Could be a sign of alignment issues, worn tires, or suspension problems. |
| Braking feels spongy or shaky | Might indicate worn brake pads, warped rotors, or air in the brake lines. |
After your drive, check for leaks under the car and make sure there’s no burning smell, as both could signal trouble. A simple test drive can catch small problems before they turn into big (and expensive) repairs.
When to seek professional help for your vehicle inspection
Taking care of basic car maintenance yourself is a great way to save money, but there are some repairs that are best left to the professionals. So, how do you know when it’s time to call a mechanic?
Some issues, like checking fluid levels, replacing wiper blades, or even swapping out an air filter, are easy DIY fixes. But when it comes to complicated systems like brakes, transmission, or electrical components, messing around without the right tools or knowledge can make things worse (and more expensive). Here are some signs that mean it’s time to bring in a professional:
| Issue | Why you should seek a professional |
|---|---|
| Your check engine light is flashing | A solid check engine light could be a minor issue, but a flashing one usually means something serious, like an engine misfire. |
| Loud knocking, grinding, or screeching sounds | Unusual noises can mean anything from worn-out brakes to major engine trouble. |
| Humming, buzzing, or whining sounds | These might indicate issues with the transmissions internal parts, such as worn bearings or gear teeth. |
| Smoke or burning smells | If you see smoke under the hood or smell something burning, pull over immediately and call for help. |
| Leaks that aren’t just water from the A/C | Oil, coolant, or transmission fluid leaks can lead to major damage if ignored. |
| Your car struggles to start or stalls while driving | This could be anything from a failing battery to a more serious fuel or ignition issue. |
| Shaky steering | This could mean you have over- or underinflated tires (which you could fix yourself) or that your wheels need to be realigned (which needs a professional). |
| Difficulty stopping | This could be anything from low brake fluid to warped rotors to worn-out brake pads or worse. |
| The engine doesn’t crank or start | This is the most common sign of a seized engine. |
