Automotive & Data Act: opening up vehicle data

The Data Act grants the user of a connected vehicle a right to access the data it generates, and the ability to share it with third parties of their choosing. This represents a major shift for automotive aftersales and independent repairers' access. This guide details the access and sharing obligations, by-design requirements, and the revision of connected services.

What is the Data Act about?

The Data Act governs access to data from connected products and associated services. The connected vehicle is a prime example, continuously generating usage, diagnostic and location data.

It complements GDPR: the latter protects personal data, while the Data Act opens access to all generated data, personal or otherwise.

Is the 'Automotive' sector affected?

Manufacturers and connected service providers are directly concerned. Data access benefits users and, at their designation, third parties such as independent repairers and insurers.

The competitive stakes are high: the Data Act aims to break situations of exclusive access to vehicle data.

Detailed obligations

Make data accessible

Enable the user to easily access data generated by the vehicle and associated services.

Enable sharing

Making data available to third parties designated by the user, such as an independent repairer.

Design by design

Integrate data access into vehicle and service design from the outset.

Ban abusive clauses

Review connected services contracts to remove unbalanced clauses.

Inform

Document, before the sale, the data generated and the access terms.

Sanctions & risks

Penalties set by each Member State, effective, proportionate and dissuasive. Beyond that, denial of access deprives the user of an enforceable right and exposes organisations to disputes with after-sales stakeholders.

The Data Act redistributes the value of automotive data — a strategic issue for aftersales and insurance.

Application timeline

  • 1Entry into force. Early 2024.
  • 2Application. Majority of obligations applicable from 12 September 2025.

Common mistakes in the sector

  • 1Locked access. Preventing the user from accessing their vehicle's data.
  • 2Sharing refused. Blocking access for designated independent repairers.
  • 3Abusive clauses. Retaining unbalanced clauses in connected services.
  • 4GDPR confusion. Believing GDPR compliance is sufficient.

Practical case

A manufacturer was restricting certain diagnostic data to its authorised network. A customer designates an independent repairer and invokes the Data Act. The manufacturer implements compliant access and sharing and revises its connected services contracts, opening up the aftersales market while securing the technical arrangements.
