What is the cost to replace an EV Motor?

The cost to replace an EV (electric vehicle) motor can vary widely depending on the make and model of the vehicle, the type of motor, and where you are located. In general, EV motors tend to be more expensive than traditional gasoline engines due to their advanced technology and specialized components.

The cost of a replacement motor can range from a few thousand dollars to tens of thousands of dollars. Additionally, labor costs for installation can also vary depending on the complexity of the job and the hourly rate of the mechanic or technician performing the work.

While the motor can be expensive to replace it is considered to be a very reliable component of the car. When compared to traditional gas engines the EV motor is considered to be much more reliable. They don’t produce as much heat, which can reduce wear and tear on the motor and its components. And because EVs don’t have a transmission, clutch, or other complex mechanical components, there are fewer parts that can fail or require maintenance.

Lets look at Tesla for example they have designed their motor to last a million miles. In general Tesla offers an 8 year / 150k mile drivetrain warranty on most of their vehicles. According to Tesla’s website it costs between $5,000 and $7,000 to replace the motor in a Model S, X or 3.

In general the motor itself being a fairly reliable part it is unlikely to fail completely and need to be replaced. It is more likely to experience less catastrophic issues such as reduced performance, strange noises, or vibrations. All of these should either be covered under warranty or cost significantly less than a complete failure and replacement would cost.

What are some components more likely to fail on an EV.

The biggest one being the battery over time it may degrade or fail. Next would be the power electronics. These include components like the inverter and converter, which are responsible for controlling the flow of electricity between the battery and the motor. Failures in these components can result in reduced performance or even complete failure of the vehicle. A couple other components that could fail would be the charging system and the regenerative braking system.


When compared to a traditional gas engine, the electric motor in an EV is a significantly simpler system. This makes for a more reliable vehicle that requires less routine maintenance and fewer repair trips to the shop for component failure.

According to Consumer Reports in their 2020 survey they found EV’s had an average reliability rating of 70 out of 100. Compared to an average reliability rating of 48 out of 100 for gas cars. This suggests that EV’s are 45% more reliable than gas cars.
