For dealerships running on an aging Dealer Management System, the decision to stay or switch has never been more consequential — or more confusing. On one side sits CDK Global, the incumbent powerhouse that processes roughly 2.6% of U.S. GDP through its systems and serves the majority of the country's 18,000 franchised dealerships. On the other is Tekion, a cloud-native startup founded by a former Tesla CIO that has raised north of $400 million and claims the architectural high ground with an AI-native, single-platform approach.
We spent weeks researching both companies: their products, pricing models, security track records, dealer sentiment, and the legal battles that now define their relationship. Here's what you need to know before choosing a DMS in 2026.
CDK Global was spun out of ADP's Dealer Services division in 2014, but its roots go back to 1973, when ADP acquired National Inventory Control System (NICS) and Computer System Inc. to provide computerized accounting and inventory systems for automotive dealerships. Through roughly 30 acquisitions over the next four decades — including Cobalt Digital Marketing in 2010 and Kerridge Computer Company in 2005 — it assembled the broadest suite of dealership software in the world. The name "CDK" itself pays homage to that acquisition history: C from Cobalt, D from ADP Dealer Services, and K from Kerridge.
In April 2022, Brookfield Business Partners acquired CDK in a deal valued at $8.3 billion, taking the company private. Today CDK serves an estimated 15,000+ dealerships across North America and operates in 25 countries globally. Its last reported revenue as a public company was $1.67 billion (2021), and it employed roughly 6,500 people. The company claims $2.9 trillion in vehicle sales runs through its systems annually — equivalent to 2.6% of U.S. GDP — and maintains 257 million unique customer IDs, 900 million anonymized repair orders, and 1,000+ integrated partners on the Fortellis platform.
But 2024 was a catastrophic year. A ransomware attack in June shut down its systems nationwide for nearly two weeks, causing an estimated $605 million in dealer losses and triggering at least eight class-action lawsuits. CEO Brian MacDonald, who took the helm in early 2024, has spent 2025 on damage control: overhauling security architecture, settling a $100 million dealer class action over antitrust allegations, and fending off a new federal antitrust lawsuit filed by Tekion in December 2024.
Tekion launched in 2016 with a radically different premise: build an automotive retail platform from scratch on modern cloud infrastructure and make artificial intelligence a foundational layer, not an add-on. Founder Jay Vijayan spent four years as Tesla's CIO, where he built Tesla's internal manufacturing and retail systems from the ground up. That experience directly shaped Tekion's architecture — a single, unified platform (the Automotive Retail Cloud, or ARC) rather than the stitched-together suite approach CDK and Reynolds and Reynolds use.
The company's product suite has expanded rapidly. The ARC platform now includes a full DMS, CRM, Advanced Analytics, Digital Retail, Digital Service Experience, Tekion Pay (payments), and Tekion Payroll. In 2025, Tekion launched AI agents for service scheduling, service advising, sales assistance, and BDC operations — all native to the platform rather than bolted on.
Tekion's funding story is impressive. The company has raised over $400 million to date. In July 2024, it closed a $200 million round led by Dragoneer Investment Group at a valuation north of $4 billion. Its cap table includes OEM strategic investors: GM Ventures, BMW iVentures, and Hyundai Motor Group — automaker money that signals the big manufacturers want a viable alternative to the legacy DMS duopoly. That OEM backing matters for dealers: manufacturers can influence — and in some cases mandate — which DMS platforms their franchisees use.
Adoption is growing but still modest compared to CDK's reach. Tekion counts roughly 2,500 dealerships on its platform. Notable customers include Group 1 Automotive (one of the largest publicly traded dealer groups), Asbury Automotive Group (running a high-profile pilot), Ken Garff Auto Group, Hartwell in the UK, and Dutch Miller Auto Group. In 2025, Tekion was named to the Deloitte Technology Fast 500 as one of the fastest-growing technology companies in North America.
CEO Jay Vijayan told Automotive News in February 2025 that he expects the company to reach profitability by early 2026. That timeline is important for any dealer considering a 6-to-9-month migration to Tekion — you want to be confident the company will still be standing when you arrive.

Pricing in DMS land is notoriously opaque — vendors rarely post public pricing and every deal is negotiated individually. But industry sources give us a reasonable picture.
CDK typically charges on a per-store, per-month basis. A typical franchise dealership running the full CDK suite (DMS + CRM + Digital Retail + F&I) pays between $15,000 and $30,000 per month. Add-on modules, data integration fees, and third-party connector costs can push that higher. CDK has also been known to charge data extraction fees when dealerships want to move their data to another platform — a practice that Tekion's December 2024 antitrust lawsuit specifically calls out as anticompetitive.
One hidden cost with CDK: the ecosystem. If you run 20-plus third-party integrations through Fortellis, your monthly integration fees can add $5,000–$15,000 on top of the base DMS cost. Dealers in our research consistently flagged surprise line items on their CDK invoices as a frustration point.
Tekion uses a similar per-store, per-month model but positions itself as 10–20% lower on total cost of ownership, in part because there are fewer add-on modules and integration costs. A full-stack Tekion deployment typically lands in the $12,000–$25,000 per month range for a mid-volume franchise store. The platform's unified architecture eliminates middleware costs — no separate DMS-to-CRM sync tool fee, no reporting data warehouse subscription, no middleware licensing.
The kicker: the migration itself is expensive. Changing DMS vendors is a 6-to-9-month project for most dealerships, requiring parallel running, data mapping, staff retraining, and often temporary staff augmentation. Budget at least $50,000–$150,000 in migration costs on top of the new monthly software fees. Both vendors offer migration assistance, but be skeptical of rosy timeline estimates — every dealer we spoke to who completed a DMS migration said the actual timeline was 30–50% longer than the initial estimate.
CDK. If you're already on CDK, adding a new module (CRM, Digital Retail, F&I) takes weeks, not months. The implementation pain is low because your data is already in CDK's systems. If you're migrating onto CDK from another system — say, Reynolds and Reynolds or a smaller DMS like Auto/Mate — you're looking at 3–6 months of data migration, parallel running, and staff retraining. CDK's partner ecosystem offers implementation consultants, but dealer forums frequently flag cost overruns and timeline slippage.
Tekion. A full Tekion migration from CDK or Reynolds typically takes 6–9 months. Tekion provides a dedicated migration team, but the process is intense: data must be extracted from the legacy DMS (which the incumbent vendor can slow-walk — one of the practices Tekion's lawsuit targets), mapped to Tekion's unified schema, validated, and then the dealership goes live in a phased rollout (usually sales first, then service, then parts, then accounting). Dealers who have completed the migration report a 2–3 month productivity dip after go-live, followed by significant efficiency gains once the team is trained on the new workflows.
Asbury Automotive's ongoing pilot with Tekion is the highest-profile test case. Early indicators suggest productivity improvements in call center operations and service scheduling. If Asbury converts from its pilot to a full rollout, it would be one of the largest Tekion deployments in the industry and a powerful endorsement for the platform's enterprise readiness.
This is arguably CDK's biggest vulnerability and Tekion's biggest selling point.
On June 19, 2024, CDK experienced a ransomware attack that took most of its services offline, disrupting thousands of car dealerships across the United States and Canada. The attack was attributed to the BlackSuit group, an Eastern European and Russian hacker collective. BlackSuit claimed responsibility and demanded tens of millions of dollars in ransom.
CDK's response was swift but costly. On June 21 — just two days after the initial attack — CDK paid approximately $25 million in Bitcoin to a cryptocurrency account connected with BlackSuit. Service restoration began on June 23, but the company advised dealers that full restoration would not be completed before June 30. The actual timeline stretched to July 4, meaning dealers were without their core DMS systems for nearly two full weeks.
The economic impact was staggering. JD Power estimated that U.S. retail unit sales in June 2024 decreased by up to 7.2% from June 2023, partly attributable to the CDK outage. Dealers collectively recorded approximately $605 million in financial losses within the first two weeks alone. Eight class-action lawsuits alleging negligence were filed against CDK by affected dealerships. Shares in CDK's parent company (Brookfield) lost over 5.7% of their value in the wake of the attack.
In a separate but related development, CDK agreed to pay $100 million to settle a class-action lawsuit alleging it conspired with Reynolds and Reynolds to fix prices and restrict data access in the DMS market — a settlement the court approved in February 2025.
CDK has since overhauled its security architecture, implemented enhanced monitoring, and brought in third-party security auditors. The company now prominently advertises a "Guard Against Connection and Security Failure" message. But trust, once broken, is hard to rebuild — especially when dealers saw their operations paralyzed for two weeks during a ransomware incident that a $1.67 billion revenue company arguably should have been better prepared for.
Tekion has suffered no major public security incidents or extended outages since its commercial launch. As a cloud-native platform built on AWS infrastructure, Tekion benefits from Amazon's enterprise-grade security certifications (SOC 2 Type II, ISO 27001) layered on top of its own application security. The platform was designed with zero-trust architecture from day one — every API call is authenticated, every data access is logged, and every component is isolated — rather than being retrofitted for security after two decades of monolithic operation. Tekion's Trust Portal provides real-time status updates and comprehensive security documentation.
That said, Tekion is also a smaller target. A company with 2,500 dealerships has a smaller attack surface — and is a less appealing victim for ransomware gangs — than a company handling 2.6% of U.S. GDP. The real test will come if Tekion achieves the scale it's aiming for. No software company is immune to security incidents, and Tekion will eventually face its own pressure test.
We aggregated dealer reviews and forum posts from across the industry to understand real-world sentiment.
Dealers running CDK generally fall into three camps:
Long-time loyalists (mostly large groups with deep CDK integrations who appreciate the ecosystem breadth). "The devil you know" is a common refrain. These dealers have CDK-trained staff, established workflows, and significant investment in Fortellis integrations.
Frustrated but locked in dealers who find the system clunky, expensive, and hard to customize. The $100 million class-action settlement over alleged price fixing with Reynolds and Reynolds did not improve sentiment. These dealers would like to switch but view the cost and disruption as prohibitive.
2024 ransomware refugees — dealers who started actively evaluating alternatives after the June outage. Industry sources report that CDK's competitive win rate dropped noticeably in the six months following the attack. Some of these dealers have already moved to Tekion or Reynolds; many more are in evaluation mode.
Common praise for CDK: ecosystem depth, OEM compliance, service lane features, accounting robustness. Common complaints: opaque pricing, data access restrictions, slow innovation, security posture, support quality.
Tekion's dealer reviews are generally positive but come with an asterisk: most reviewers are early adopters who chose Tekion specifically because they wanted a modern platform. That self-selection bias is real.
Common praise: interface usability (significantly better than legacy DMS options), AI features (T1 conversational interface, Service AI agents), single-platform data visibility (no "please talk to Bob in accounting for that report" moments), analytics quality, and support responsiveness.
Common complaints: smaller integration ecosystem (you may need to maintain some legacy systems in parallel), migration pain (inevitable with any DMS switch), middle-market lender gaps in F&I, and the nagging question of long-term viability — what happens if Tekion doesn't make it?
That last concern is the most frequently voiced on dealer forums. It's a fair question for a company that, as of early 2025, was still burning cash on its path to profitability. Jay Vijayan's promise of profitability by early 2026 is encouraging, but the company's track record of meeting targets matters — and so does the financial stability of its backers (Brookfield's deep pockets vs. Dragoneer's growth capital).
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 their own operations data, making it harder for dealers to switch to alternative management systems. The lawsuit accuses CDK of "bullying" tactics and anticompetitive behavior designed to maintain its market dominance.
This lawsuit is not happening in a vacuum. CDK paid $100 million in a class-action settlement over very similar allegations — that it conspired with Reynolds and Reynolds to charge unlawful prices and block third-party data access. The California court approved that settlement in February 2025, in a class covering dealerships doing business with CDK from September 2013 through August 2024.
The legal case against CDK is building, but it's slow. Class actions take years. The Tekion lawsuit may be resolved faster given that both parties are active competitors, but don't expect a ruling before 2027 at the earliest. In the meantime, the existence of the lawsuit gives dealers negotiating leverage: when CDK quotes you a price, you can credibly say you're evaluating Tekion.
You are an independent dealer (1–3 stores) where the decision comes down to local support quality, individual pricing negotiation, and which manufacturer OEM partners prefer. At this scale, the quality of your implementation partner and ongoing support relationship often matters more than platform architecture.
The CDK vs Tekion decision in 2026 is less about features and more about trajectory. CDK is the established market leader with unmatched scale, a vast integration ecosystem, and deep OEM relationships — but it is carrying the weight of a 50-year-old tech stack, the scars of a major security incident, and lingering antitrust baggage. Tekion is the insurgent with the better architecture, a clean security record, and compelling AI capabilities — but it is still building its ecosystem and has not yet proven it can handle the full complexity of the largest dealer groups at scale.
The smartest approach for most dealers: do not treat this as a binary, all-or-nothing decision. If you are a large group, run a pilot on 2–3 stores — the way Asbury and Ken Garff are doing — before committing to a full migration. If you are an independent dealer, Tekion's single-platform simplicity is compelling, but verify that your specific OEM accounting requirements and lender integrations are fully supported before signing.
One thing is certain: the CDK-Tekion rivalry now runs through the courts, and the outcome of that litigation could reshape the DMS market more than any product feature ever could. For now, dealerships have more leverage than ever to negotiate favorable terms from whichever vendor they choose. Use it.
