The Top 5 Most Expensive Auto Repair Problems


Any car owner can testify that upkeep can be incredibly expensive, especially if you skip regular maintenance. Avoiding regular tune-ups and oil changes, or ignoring the check-engine light can lead to costly auto repair services:

1. Fixing/Replacing the Cylinder

Ignoring small problems inevitably leads to bigger, more expensive problems. The need to fix or replace a cylinder is usually a sign of continued neglect. Fixing or replacing a cylinder can cost upwards of $8,000 because of the labor involved.

Cylinder failure occurs when the correct mixture of air, fuel and sparks are missing. The cylinder overheats and fails – but not without plenty of warning signs, such as misfires and other issues. In fact, with regular maintenance, this problem is virtually nonexistent.

2. Replacing the Hybrid Inverter Assembly

This auto repair is costly because Hybrid parts aren’t readily available. As the model becomes more popular, the price may drop. Since the only warning for this problem is the check-engine light, inverter failure can be hard to detect.

The inverter is responsible for converting direct-current power to alternating-current power. It doesn’t often fail, but when it does, replacing the assembly can cost anywhere between $4,000 and $7,400 depending on the vehicle model.

3. Replacing the Transmission Assembly

Without a functioning transmission, your car wheels are unable to turn. Transmission problems can often be headed off with regular maintenance, especially if you follow your manufacturer’s guide for routine services. Replacing the assembly can cost at least $3,600 or more.

4. Replacing the Cylinder Head and Spark Plugs

Spark plug failure needs to be addressed immediately. Continuous misfires in your engine will cause the cylinder to heat up and fail. In fact, unless the problem is addressed right away, engine failure is inevitable – and costs up to $8,000 or more.

How do you know that your spark plugs are having problems? For most vehicles, the check-engine light will begin to blink, indicating a misfire. Mechanics strongly recommend that you stop driving the car immediately because you’re now doing serious damage to the engine. Auto repair of this kind can cost up to $3,500 or more, even if it’s taken care of right away.

5. Replacing the Camshaft

The camshaft is responsible for controlling how your engine takes in air. Unless maintenance is neglected, you most likely won’t have a problem with this assembly. Problems arise when grime and dirt build up on the valves.

Replacement cost for a camshaft can cost anywhere from $1,600 to $3,100. This auto repair is very labor-intensive, which is the primary reason for the high cost. However, if you change your oil regularly and have your valves cleaned, it’s unlikely that you’ll have problems.

Regular Maintenance is Key

In order to avoid many of these expensive auto repair issues, keep up with regular maintenance like oil changes and tune ups. As you may have noticed in the descriptions above, your check engine light should not be ignored. It’s often one of the first indicators that there’s a problem. Getting it checked right away can avoid more serious damage later on.
