As automotive repair costs continue to climb, a growing number of drivers are turning to do-it-yourself diagnostic tools to understand and address vehicle issues before visiting a mechanic. Industry data indicates that the average cost of a professional diagnostic scan at dealerships and repair shops ranges from $100 to $300, creating a significant market opportunity for consumer-friendly diagnostic devices.
A comprehensive report by TOPDON and global data platform Statista, which surveyed 2,800 vehicle owners across North America and the U.K., reveals that 97% of current consumer diagnostic tool users can now spot issues faster, 94% have a better understanding of their vehicles, and 93% have avoided unnecessary technician visits . The report, titled "The State of DIY: How Home Diagnostic Tools Can Empower Car Owners," identifies rising repair costs and growing interest in independence as key motivators behind the shift toward DIY vehicle maintenance .
"With rising repair costs and greater interest in independence, car owners are getting more involved in vehicle care," said Mike Zhou, founder of TOPDON. "Online training and more accessible information are making DIY repairs easier than ever" .

The FIXD OBD2 scanner has emerged as one of the most popular solutions in this expanding category. The Bluetooth-enabled device, which plugs directly into a vehicle's onboard diagnostics port, reads engine fault codes and translates them into plain English through a companion smartphone application . Since its launch, the Atlanta-based company has sold over 4.5 million sensors, reflecting substantial consumer appetite for accessible automotive technology.
The device works with all 1996 and newer gasoline-powered vehicles, as well as diesel models from 2006 onward. Once plugged into the diagnostic port, typically located under the dashboard near the steering column, the sensor communicates with the vehicle's computer system and relays diagnostic information to the user's phone. The free version of the application provides code definitions, severity ratings, and maintenance reminders, enabling drivers to make informed decisions about whether to seek immediate repairs or schedule service at their convenience .
Consumer reviews across multiple platforms indicate strong satisfaction with the product's core functionality. The FIXD app maintains a 4.6 out of 5 rating on the Apple App Store, while Google Play users have awarded it 4.2 out of 5 stars from over 29,000 reviews . Independent testing has confirmed that the scanner accurately reads standard OBD2 engine codes, matching results obtained from professional-grade diagnostic equipment .
However, the product's premium subscription model has drawn scrutiny from some users. While the basic diagnostic features remain free, advanced capabilities including repair cost estimates, a live mechanic hotline, and vehicle history reports require a Premium subscription priced at approximately $99.99 annually. Consumer complaints filed with the Better Business Bureau reveal that 548 complaints have been lodged against the company in the last three years, with 102 complaints closed in the last 12 months alone . Many of these complaints center on unexpected recurring charges following free trial periods, with some consumers describing difficulty in canceling subscriptions or feeling that the recurring charges were not sufficiently transparent at the point of purchase.
The company has responded to these concerns by offering refunds to customers who contact support regarding unauthorized charges, according to user accounts across review platforms and BBB complaint resolutions. One complainant noted that FIXD's support team responded within one business day, stating: "We have canceled your premium subscription and issued you a refund" . FIXD Automotive maintains that the Premium subscription is clearly marked as optional during checkout and includes a free trial period that users may cancel at any time.
The scanner's capabilities are not without limitations. The device reads only engine-related diagnostic codes and does not provide access to ABS, airbag, or transmission system data . For consumers requiring comprehensive vehicle diagnostics, alternative products such as the BlueDriver scanner offer broader system coverage, though at a higher initial price point of approximately $100 with no recurring subscription fees.
Industry analysts note that the growing popularity of consumer diagnostic tools reflects a broader shift in automotive maintenance culture. Recent data from Circana reveals that 29% of consumers reported switching from having a professional change their automobile's oil to doing it themselves to save money . Higher-income households earning $100,000 or more annually have driven the largest growth in the DIY retail aftermarket in recent years, initially spurred by increased free time during the pandemic and more recently by cost-saving measures .
"There are 20 million more vehicles in the aftermarket 'sweet spot' — those beyond their original warranty — than there were in 2020," said Nathan Shipley, automotive industry analyst for Circana. "Older cars mean more maintenance activity, but the cost of that maintenance can add up fast, leading consumers to find ways to save, including taking on some of it themselves" .
For prospective buyers, industry observers recommend evaluating diagnostic needs carefully before making a purchase. The FIXD scanner offers substantial value for drivers seeking an affordable entry point into vehicle diagnostics, but those requiring coverage of multiple vehicle systems or preferring a subscription-free experience may find better alignment with alternative products in the increasingly competitive consumer diagnostics market.
