Cost of replacing side mirrors


We introduced the mirror cover, mirror, and motor, but we will also introduce the cost of replacing the side mirror body and whether it can be replaced by DIY.

The price of the side mirror body tends to be high, and the amount varies depending on the manufacturer.

The price of the side mirror body is about 50,000 yen to 100,000 yen, and the side mirrors of light cars tend to be cheaper than those of light cars and passenger cars.

In recent years, many cars are equipped with an around view monitor camera, mirror heaters, and door mirror turn signals as one of the genuine equipment. Aiming work is required, and adjustment and setting fees will be incurred in addition to replacement costs.

DIY work does not require disassembly if the mirror body is to be replaced, and can be easily replaced if no special tools are used.

However, if you have to adjust the camera, you can’t do it yourself, so be careful that you will need to adjust it at a dealer after replacing it separately.

When can you not repair mirrors?

The cost of replacement is expensive, and it is best to reduce the price by repairing, but depending on the condition of the mirror, repair may not be possible.

  • Internal motor failure
  • wiring short
  • Large external damage
  • The parts for the faulty part are not sold

In the above example, it is one of the symptoms when repair is not possible depending on the manufacturer, and depending on the model etc., it may be possible to replace the broken part separately. Whether or not it can be repaired requires a diagnosis and parts search.

How to replace the side mirror cheaply?


There are several inexpensive repair methods for replacing mirrors, which tend to be expensive in repairing side mirrors, and we will introduce them.

use a rebuilt product

When replacing parts at a repair shop such as a dealer or an auto supply store, normally, the manufacturer’s genuine parts are purchased new and the replacement work is performed.

However, the parts of the car are expensive depending on the parts, and the repair cost is high.

Among them, the repair method using rebuilt products is one of the very effective means as a cheap and safe method.

Remanufactured products, which are assembled by disassembling and cleaning the parts that have been used once and replacing only the parts that cannot be used. There is no problem with the quality, and even if there is a problem after the replacement, you can have it covered by the warranty, so you can rest assured.

In addition to side mirrors, rebuilt products include various parts such as engines, alternators, and drive shafts.

In addition, many dealers also sell rebuilt parts, and Nissan has a product called “Nissan Green Parts”, which sells rebuilt parts with high standard quality.

buy second hand parts

You can buy new parts online, but you can also buy second-hand parts at online auctions or auto parts stores.

One of the appeals of used parts is that they can be purchased at a much lower price than conventional ones.

If the mirror itself doesn’t work due to motor failure, etc., rather than cracks or scratches on the mirror cover or mirror, if the working surface is more important than the appearance, it may be better to buy second hand.

replace under warranty

If there is a defect or malfunction at the time of purchase of the new car, it is possible to replace or repair it free of charge by the repair method using the manufacturer’s warranty.

We cannot cover malfunctions or failures caused by external factors such as hitting the mirror, but we can cover malfunctions of the internal motor, short circuits in wiring, etc., so the mirror will suddenly operate. If not, we recommend that you have it checked by a dealer.

Possibility of handling by recall

Depending on the vehicle model, it may be possible to replace or repair due to recall defects.

As an example, in Nissan Days and Days Lukes, there are cases where the warranty is extended due to a mirror storage defect due to wear and damage of internal parts, and depending on the mileage and the number of years since the new car was registered, you may be able to get it free of charge. .

Apart from the warranty, you can check with your dealer to see if your car is covered by the recall.

Should I use vehicle insurance to repair or replace side mirrors?


When it comes to replacing the mirror body, the cost may be about 50,000 to 100,000 yen, so it is not a cheap amount.

If there is an internal defect or the manufacturer’s recall service campaign, it is possible to have it replaced or repaired free of charge, but in many cases it will be a paid repair.

Repairs and replacements using insurance that you subscribe to while driving a car are applicable.

However, repairs using insurance are very few and most users replace them at actual cost. The reason is below.

  • grade goes down
  • Depending on the type of insurance, the deductible amount (copayment amount) is set
  • Insurance coverage changes depending on self-inflicted accident or accident

Do not use car insurance in a car accident

Auto insurance has a system called “non-fleet grade”, and depending on the history of accidents, there are grades from 1 to 20, and by raising or lowering, the amount will be discounted or increased.

If you apply insurance for one repair or replacement, the grade will be lowered and the amount will be raised, and the period until the grade will return is very long, so many people do not use vehicle insurance.

Depending on the type of insurance, you may have to pay the deductible amount yourself, so if the cost of repair or replacement is cheap, it may be cheaper not to use insurance.

However, if the mirror is damaged due to an accident, etc., it is possible to repair it using the other party’s objective guarantee. In this case, repair or replacement using insurance is one of the effective means.
