Monopolies and Restrictive Trade Practices Commission issued a notice to Maruti Udyog Ltd on Monday over a complaint by Hyundai Motors against a sales advertisement of the car maker.
Accepting the Hyundai petition filed on Friday, MRTPC asked Maruti to send its reply within two weeks.
The matter has been listed for further hearing on September 27.
The two car makers have come face to face after Hyundai challenged a sales pitch of Maruti in its latest advertisement campaign, saying it was 'misleading and disparaging'.
Hyundai had said Maruti was indulging in unfair trade practices and sought relief from MRTPC.
