This guide will tell you how to fix the mechanic not working problem in Grand Theft Auto 5.
The first thing you will need to do is boot up your game and once the game starts, you have to press the M button on your keyboard to open the interaction menu. After that, select the Vehicle option where you have to return your personal vehicle to storage.

After this, open your phone and then call your mechanic. Once the mechanic receives the call, you have to request your personal vehicle. If the mechanic does not receive the call, then you need to pay him for the delivery of the vehicle; otherwise, he will not deliver any vehicle to you. You need to make sure that you have some money in your bank account to pay the mechanic.
