Antitrust lawsuits
In May 2017, CDK was sued, along with DMS supplier Reynolds and Reynolds, by data integration service provider Authenticom, which alleged that the two companies engaged in anti-competitive conduct and violated antitrust law by conspiring to block third-party access to their data systems in order to create a duopoly.[41][42] In July 2017, District Judge James Peterson granted a preliminary injunction against CDK and Reynolds and Reynolds, ruling that there was sufficient evidence to find "the existence of a per se illegal horizontal conspiracy" between CDK and Reynolds and Reynolds to divide the data integration market between them and block competitors, and requiring the two companies to "cease blocking Authenticom" from providing "data integration services to dealers who authorize Authenticom to provide this service."[42][43] In November 2020, CDK settled its lawsuit with Authenticom, agreeing to make a one-time cash payment to Authenticom.[44]
CDK agreed to pay $100 million plus $250,000 for notice and administration costs to resolve claims involving an alleged conspiracy by CDK and Reynolds to charge unlawful prices in the markets for DMS Services and Data Integration Services. Dealerships doing business with CDK from September 1, 2013 through August 15, 2024 were invited to join a class action lawsuit that paid out the settlement. On February 25, 2025, the court approved the settlement payout.
In 2018, software vendor Autoloop sued CDK for violating antitrust law, accusing CDK of restricting access to data and causing vendors to pay hundreds of millions of dollars in overcharges. The lawsuit was granted class action status in July 2024.[45]
In December 2024, Tekion filed a federal antitrust lawsuit against CDK, alleging that CDK attempted to illegally monopolize the DMS market by withholding or delaying dealers' access to operations data, making it harder for dealers to switch to alternative management systems and leading dealers to pay higher prices.[46]
