When the dreaded check engine light comes on, you get that sinking feeling in your stomach. You're probably about to drop a lot of money on an expensive car repair. If you're lucky, it could be something simple, but you had better hope it's not one of these expensive repairs!
Rounding out the top 10 of most expensive car repairs is a fuel injection pump replacement. This pump is responsible for moving fuel from the tank into the engine, and it's crucial to the operation of the engine. Replacing this part is fairly simple, but the pump is often located in a spot that requires a lot of extra effort to access. The cost will vary depending on your make and model.
Estimated Cost: $400 - $600
9. Catalytic Converter
If you live in an area that requires emissions testing for cars, then you most likely have a catalytic converter. This device is used to convert the harmful chemicals in exhaust fumes into harmless ones. It's a very useful device, but it's also an expensive one. Luckily, the catalytic converter is located between the engine and the muffler, so it should be easy for a mechanic to replace. You can still expect to pay quite a bit for this repair job.
Estimated Cost: $400 - $800
It's really amazing how few people are seriously injured in car accidents, and the main reasons why cars are so safe are the airbags. The only problem with airbags is that they're somewhat fragile. Once they go off, they usually need to be replaced. In addition, the force of airbag deployment can damage surrounding parts, like the steering wheel or the glove box.
Estimated Cost: $500 - $1000 (per airbag)
7. Air Conditioning
Just imagine driving around in the summer without using the air conditioning in your car. Having that nice, cool breeze is crucial for most people, but fixing a broken A/C unit can be very pricey. Just having the system checked and "recharged" will set you back a few hundred dollars, but a serious repair job will cost even more.
Estimated Cost: $800 - $1,200
More and more car manufacturers are making mid and upper-level models with turbos installed stock. Turbochargers are used to force more air and fuel into the engine's cylinders, which results in faster acceleration. If your car has a turbo, your car make a whining noise as you accelerate and a slight hiss when shifting gears. The part alone is very expensive, so replacing it is never cheap.
Estimated Cost: $1,000 - $1,500
5. Suspension System
A car's suspension is something that you won't notice at all when it's working correctly. It's what keeps you from feeling every little bump and dip in the road. Unfortunately, it's made up of a lot of different parts. Here are the most important parts of the suspension system:
Usually, only one set of these parts needs to be replaced at a time, but a complete suspension overhaul will get really costly in terms of parts and labor.
Estimated Cost: $1,000 - $2,000
4. Camshaft and Lifters
Despite looking like a crazy jumble of twisted steel, a combustion engine isn't extremely complicated. The camshaft is a rotating rod that is used to fire the engine's cylinder's in a repeating pattern. The camshaft doesn't directly activate the cylinders, but instead actives the lifters which do that job. These parts are relatively expensive, and replacing them can take up to 12 hours of labor.
Estimated Cost: $2,000 - $2,500
3. Transmission Assembly
The transmission assembly is probably the most complicated piece of machinery in your car. It's an impressive collection of gears and levers that allows your car to shift (now you know why it's called shifting gears). Replacing a transmission is extremely expensive, and it takes many hours of intense labor. Only use a trusted mechanic or a dealer to take care of a major job like this.
Estimated Cost: $2,000 - $4,000
2. Hybrid Battery
Hybrid cars are all the rage right now, but many people don't know that there is a massive hidden cost of ownership for this new type of vehicle. Any rechargeable battery slowly loses its ability to hold a charge over time, and hybrid car batteries will likely die before 10 years of use. Replacing this battery usually also means replacing the computer system for the car. The cost varies widely depending on the car.
Estimated Cost: $2,000 - $6,000
If your mechanic ever comes back to you and says the words "major engine damage" then you're in big trouble. Those words probably mean that something has damaged the cylinders at the core of the engine. Your mechanic will have to remove the entire engine from the vehicle and your best option is to get a whole new engine rather than repair the old one. Large and powerful engines will be more expensive than smaller ones.
Estimated Cost: $3,000 - $7,000
