Most common car repairs are simple enough that any car owner can handle it themselves—even if they have no prior experience with automobiles. However, don’t let yourself get so caught up in learning how to fix your car that you neglect to take your car in to the professionals when you should. Some car repairs are too complicated for an amateur to attempt. Here are a few you should leave to the pros, because you’re more likely to damage your car.

1. Technology-Related

Over the last few years, cars are becoming more computerized, sometimes seeming to function more as electronic devices than automobiles. If something happens to the electronic devices in your car—whether it’s the plug that you use to charge your car or the entire display console in the passenger cabin—computers are complicated, and you’re more likely to break something beyond repair if you try to fix it yourself. You’ll save money if you take your car into the repair shop immediately, and let the experts worry about the problem.

2. Brakes

Although replacing the brake pads is an easy DIY auto repair, most other issues with your brakes aren’t something you want to risk handling by yourself, especially if you’re an amateur. From the rotors to your hydraulics, brakes are complicated, and every time you’re behind the wheel, your life (and all those in the car with you) depends upon them. If you hear your brakes squeaking or grinding, get your car into an expert. Mechanics who can work on the industrial-grade Rexroth Hydraulics are sure to be able to handle your standard vehicle. Don’t risk your safety. Keep your brakes in working order.

3. Transmission

It’s easy to tell when a car has problems with its transmission. It could be making a sound that it’s never made before, or maybe it takes it a few moments to shift from park into reverse or drive. Whatever the problem, you should get it looked at. Your transmission is one of the most expensive parts of your car, and unless you’re changing the transmission fluid, any problem is going to be too complicated for an amateur to tackle. You could end up causing more damage to your transmission, making it even more expensive to fix than it would typically be. Let your auto shop handle the repairs.

4. Engine

When the “Check Engine” light comes on, don’t ignore it. That little light could be indicating something as simple to fix as a loose cap or a spark plug. Or it could indicate a damaged catalytic converter. It’s simple enough to figure out what the check engine light is on for—any auto shop can hook up your car to a little computer that will read what the problem is. If it’s a simple fix, that’s great, but if it’s more complicated don’t hesitate to take your car in. The longer you drive without getting your car serviced, the more dollars you’ll fork out to fix the problem.

It’s great to save money fixing your car yourself, and when you’re just changing the air filter or wiper blades, it’s unlikely you’ll cause any damage. But if your car has major issues in the above areas, let the experts handle the necessary repairs.
