Relating to the diagnosis, maintenance, and repair of certain motor vehicles; providing a civil penalty.

SB 2748 creates new rules for motor vehicle diagnosis, maintenance, and repair in Texas by defining key terms like "barrier" (restrictions preventing owners from choosing repair facilities or using aftermarket parts) and "critical repair information" (tools, schematics, and data needed to fix vehicles). The bill requires manufacturers and dealers to provide this information to owners and independent repair shops, aiming to remove barriers that limit repair choices. It directly affects vehicle owners, independent repair facilities, and manufacturers by mandating access to necessary repair tools and information. Violations could trigger civil penalties, though specific penalty amounts aren't detailed in the provided text. This bill focuses on expanding repair options without specifying outcomes or taking sides on the debate.
