In letters sent to manufacturers, dealerships, and industry group SIMI, the CCPC reminded businesses that consumers must be free to choose where their vehicle is serviced or repaired and which parts are used—without fear of losing warranty coverage.

The warning comes after motorists reported being discouraged from using independent garages. Some were told their warranties would be void if work was carried out outside authorised dealerships or if non-original parts were used. Others cited blocked access to essential diagnostic data and tools, which independent garages need to perform services.

The CCPC said such restrictions may breach competition law, raising costs for consumers and harming smaller service providers.

Independent garages were also reminded of their legal rights: they may use spare parts of “matching quality” and carry out services without affecting vehicle warranties, as long as the work is done competently.

Distributors have been asked to review their practices and provide relevant information by 6 August. Although no formal legal action has been taken, the CCPC said it will not hesitate to act where it finds illegal restrictions.

CCPC Director of Antitrust, Craig Whelan, stated: “Motorists must be free to choose where they service their vehicles and what parts they use. These restrictive practices hurt consumers and stifle competition.”

The regulator is encouraging garages to report any barriers they face, including restricted access to tools or data. Penalties for breaches of competition law can reach €10 million or 10% of annual global turnover—rising to €50 million or 20% in serious criminal cases such as cartel activity.
