The 6 Most Expensive Car Repairs and How to Avoid Them

There are few worse feelings in the world than turning on your car to find a cacophony of sounds and blinding lights show that should charge tickets for performances at the planetarium set to psychedelic rock music. While it’s a fact of life that cars are going to face repairs at some point in their life, some maintenance simply costs more — a lot more — than others. Depending how well you know cars, when the check engine light or any other warning sensor pops on, you could face a repair ranging from a few hundred to several thousand dollars.

Your car will take on wear and tear over time and as you drive it; however, there are vehicle care tips to dodge avoidable car repairs as long as you follow them and care for your car, truck, or SUV. Let’s look at the six most expensive car repairs and what you can do to avoid them.

Electric/Hybrid Batteries

As years roll on, electric and hybrid vehicles become more popular (though they are still outnumbered by the common fuel-powered engine vehicles). So, while this is a niche issue, it is no less one of the costliest repairs an electric or hybrid car, truck, and SUV owner can face.

The batteries are designed to last 10 years, give or take, but there are cases where they die sooner.

How do I avoid EV battery replacement?

Follow the manufacturer’s charging instructions. Some simple tips are to keep your battery at around 80% charge, limit the use of speed chargers, and precondition your vehicle.

Catalytic Converter

If you’ve avoided emissions issues in your vehicles to date, you can thank your catalytic converter. The real sticker shock from this repair doesn’t come from misuse necessarily, but theft. Catalytic converters should last around 10 years, but because the part itself is so expensive — make up most of the repair cost — they’re a prime target for people to steal.

Park your vehicle in a safe, well-lit area, and consider adding anti-theft safety measures to your vehicle.

Head Gasket

Your engine is the workhorse of your vehicle, and the head gasket keeps everything tightly sealed to avoid leaks from fluids such as coolant and oil. Once the head gasket goes, your engine will drip fluids and begin overheating, leading to other costly repairs. You’ll know you have a blown head gasket when you see smoke coming from your tailpipe.

Head gasket preventative maintenance

There aren’t many things you can do to avoid a head gasket eroding or going missing other than constantly checking on it. Make sure your engine doesn’t have coolant leaks elsewhere to avoid overheating; this is the main cause of a blown head gasket.

Timing Belt

The timing belt regulates the valves and pistons in your engine. If the timing belt falls out of sync or fails entirely, your car may not turn on, or it will damage the engine as the pistons and valves won’t work properly, leading to overheating. Replacing your timing belt could be a few hundred dollars, or it could be a few thousand dollars. Operating your vehicle with a faulty timing belt for too long could lead to more costly engine repair issues.

How do I avoid a failing timing belt?

There isn’t much you can do in terms of preventative maintenance when it comes to a timing belt. To avoid any costly damage or unforeseen breakdowns, make sure to follow the recommended replacement schedule per the vehicle’s manufacturer.

Engine

There are several ways that an engine can blow, but the main takeaway is that it will be costly. Usually, however, there was a leak, or the oil wasn’t changed frequently enough, leading to sludge buildup. When sludge builds up and/or oil can’t properly lubricate all the moving pieces, parts gnash against each other due to friction, and then everything overheats. Rebuilding an engine will cost you a few thousand; replacing an engine is significantly more expensive.

Engine preventative maintenance

Perform regular oil changes to keep everything lubricated, look for leaks under your car when it’s been parked, and don’t put off going to a service center if your engine light comes on.

Transmission

For those who have had to deal with transmission maintenance issues in the past, you know this is one of the biggest headaches for vehicle owners. If you’ve dodged transmission troubles to this point, consider yourself lucky. This repair bill will always be several thousand dollars. The good news is that transmissions are engineered and manufactured to last for a long time as long as fluid levels are maintained. If you notice strange sounds when you’re in neutral, unusual smells, or your vehicle slipping into or out of gear, you likely have a transmission issue on your hands but will need to go to a service center for diagnostics.

Transmission Preventative Maintenance

Flush your transmission and keep the transmission fluid fresh and topped off. Always follow your manufacturer’s recommended service schedule.
