Frequently Asked Questions

How Can Fleet Service Help Reduce Unexpected Downtime?

Consistent fleet service gives technicians more opportunities to identify worn components, fluid issues, brake concerns, and developing mechanical problems before they interrupt scheduled work. Maintenance can also be planned around vehicle usage to reduce unnecessary time out of service.

Can You Build a Maintenance Schedule Around Our Fleet’s Workload?

Yes. Maintenance intervals can be planned around mileage, engine hours, equipment use, operating conditions, and manufacturer recommendations. This gives fleet managers a more practical schedule than servicing every vehicle or piece of equipment at the same interval.

Can Fleet Repairs and Maintenance Be Prioritized Around Our Schedule?

Yes. We can help prioritize vehicles based on service needs, upcoming routes, job requirements, maintenance intervals, and current mechanical concerns. This helps fleet managers decide which units need immediate attention and which repairs can be scheduled around operations.

Do You Provide On-Site Maintenance for Commercial Fleets?

Our mobile technicians can perform qualifying fleet maintenance and repairs at yards, facilities, and job sites when bringing every vehicle to the shop is inefficient. On-site service can be particularly useful for scheduled maintenance programs and fleets with multiple vehicles due for service.

‍Can Hex 6 Handle DOT Compliance for our Fleet?

‍Yes. We perform DOT inspections and can handle all required repairs to bring vehicles into compliance. We also provide the documentation fleet managers need for compliance records.
