How Much Does It Cost to Repair Semi Truck?

Semi trucks, also known as semi-trailer trucks, tractor-trailers or 18-wheelers, are an essential part of the global freight industry. Without them, it would be impossible to move goods from one place to another in an efficient and cost-effective manner.

But like any other type of vehicle, semi trucks require regular maintenance and repair in order to keep them running reliably. The cost of such repairs can vary significantly depending on the type and severity of the issue.

Repair costs for minor issues such as oil changes and tune-ups are typically relatively low. These types of repairs can range from a few hundred dollars for basic services to a few thousand for more complex repairs that involve replacing parts like spark plugs or air filters. Additionally, many semi truck owners will opt for scheduled preventative maintenance services like alignments or brake replacements which can cost anywhere from $500 – $2000 depending on the scope of work required.

Major repairs such as engine replacements or transmission rebuilds are significantly more expensive than minor repairs due to the complexity involved in taking apart and reconstructing these components. Depending on the make and model of your semi truck, you could be looking at anywhere from $10,000 – $20,000 or more for these types of repairs.

When it comes to buying replacement parts for your semi truck, you’ll often find yourself paying a premium due to the specialized nature of these components. Parts like tires, batteries, and even fuel injectors can all be extremely expensive when compared to what you would pay for similar parts on a regular passenger vehicle.


Overall, the cost of repairing a semi truck depends heavily on the type and severity of any issues that need to be addressed. Minor repairs such as oil changes and tune-ups are typically quite affordable while major repairs like engine replacements can run into thousands or even tens of thousands of dollars. Additionally, specialized parts needed for semi trucks can often be substantially more expensive than those needed for regular vehicles.
