The manufacturer of an automobile is required to provide access to data that make it possible to identify a problem and maintain or repair the automobile.. This may include diagnostic trouble codes, data to calibrate a part or identify the required replacement parts, etc.
If you are dealing with a mechanic that is independent of the manufacturer, the manufacturer must provide them with access to the data.
The data must be accessible in a format that is legible and free of charge or at a reasonable cost.
How to enforce your rights
What if your vehicle needs to be repaired, but the manufacturer refuses to give you access to certain data? If the data to which you do not have access are required to repair the vehicle, you can ask the manufacturer to make the repairs at their expense.
The manufacturer then has 10 days to notify you in writing of how long it will take to complete the repairs. If the manufacturer does not reply or fails to abide by the time frame they have indicated, you can claim a reimbursement or a replacement vehicle, at the manufacturer’s discretion. You must then return the vehicle.
If the manufacturer fails to abide by their obligations, and negotiations and sending a formal notice have not solved your problem, you can initiate court proceedings against the manufacturer.
Among other things, you may seek:
- enforcement of the manufacturer’s obligations;
- payment of damages, if you have suffered harm (which you must be able to prove and quantify).
