Conduct full vehicle inspections for safety, emissions, and pre-sale or post-accident assessments; document findings, recommend repairs, and estimate parts and labor with accuracy.
Use OEM repair information, technical bulletins, and diagnostic flow charts to produce consistent, warranty-eligible repairs and to reduce comebacks; apply software updates and calibration files where required.
Perform scheduled maintenance services (oil changes, multi-point inspections, fluid services, tune-ups, timing belt/chain replacement) adhering to factory-recommended intervals and service specifications.
Install mechanical and electrical accessories, retrofit components, and perform aftermarket system integrations while ensuring compatibility with OEM electronics and maintaining warranty status when applicable.
Conduct road tests and post-repair verification checks to validate repairs under varied driving conditions; document test results and ensure customer satisfaction before vehicle release.
Order and manage parts for repairs, verify parts fitment, receive deliveries, and coordinate special-order or back-ordered items with parts department and customers.
Prepare accurate repair orders, detailed labor time entries, diagnostic notes, and parts documentation in the shop management and CRM systems; close jobs with clear work descriptions and follow-up recommendations.
Manage warranty and goodwill claim documentation; prepare technical reports, support service advisor submissions, and follow up with manufacturer or parts supplier when required.
Maintain shop equipment, diagnostic tools, lifts, and calibration devices; perform routine preventive maintenance and ensure tools are calibrated and compliant with industry standards.
Ensure compliance with environmental, safety, and regulatory standards (EPA, OSHA, DOT) including proper handling and disposal of hazardous materials, refrigerants, and used fluids.
Mentor and train junior technicians and apprentices in diagnostic techniques, OEM procedures, safe practices, and efficient work habits while promoting continuous learning and certification progress.
Communicate directly with customers and service advisors to explain complex technical issues in plain language, provide repair timelines and cost estimates, and set realistic expectations for outcomes.
Collaborate with collision, body, and paint technicians to coordinate repairs that involve structural or multi-shop workflows; ensure seamless handoffs and unified repair strategies.
Utilize computerized service manuals, online parts catalogs, and diagnostic subscriptions to research uncommon failure modes and engineering change notices for legacy and current model vehicles.
Maintain a clean, safe, and organized work area, enforce shop housekeeping standards, and contribute to efficient bay scheduling to support overall shop productivity and customer throughput.

Secondary Functions

Assist with inventory counts, parts stock rotation, and identification of slow-moving SKUs to help minimize delays and parts shortages.
Support service advisors by preparing customer-facing repair explanations, repair photos, and video walk-throughs to improve transparency and customer trust.
Participate in continuous improvement initiatives, shop performance reviews, and technician scorecards to identify training and process optimization opportunities.
Provide technical input for seasonal service promotions, maintenance packages, and service menus to increase revenue and customer retention.
Help manage loaner or fleet vehicles, perform pre-checks and return inspections, and maintain service records for corporate or fleet accounts.
Aid in the onboarding of new technicians by assisting with shop orientation, safety briefings, and OEM tool familiarization.
Assist warranty and claims administrators by providing technical documentation, diagnostic logs, and technician statements when filing manufacturer claims.
Support recall campaigns by performing recall-related inspections and repairs, documenting compliance, and ensuring proper completion of software updates.
Participate in field service calls or mobile repair work when required to support technicians off-site and complex diagnostic tasks at customer locations.
