Will i have to pay for a faulty repair my car?

It depends on the circumstances. If the repair was done correctly and the fault is due to a manufacturing defect, then the manufacturer may be responsible for the repair. If the repair was done incorrectly, then the repair shop may be responsible for the repair. If the fault is due to wear and tear, then you may be responsible for the repair.

Generally, if the fault is due to a manufacturing defect, the manufacturer will be responsible for the repair. However, if the fault is due to wear and tear or incorrect installation, then you may be responsible for the repair. It is important to check the warranty of the repair before you have it done to see what is covered and what is not.

If you are not sure who is responsible for the repair, you can contact your local consumer protection agency. They will be able to help you determine who is responsible and what your options are.
