DAS Fleet Services - Maintenance and Service

All State-owned motor vehicles require routine maintenance, and at times need repairs. Contracted providers for vehicle maintenance and repairs are available for all State agencies. DAS Fleet Services also allows use of non-contracted service providers when a contracted provider is not available. If a State vehicle needs maintenance or repairs, please use a contracted provider whenever possible.

In the Des Moines Metro area: Contact DAS Fleet Services at 515-281-3162 to schedule maintenance for a State vehicle. Upon scheduling, the vehicle may be dropped off at DAS Fleet Services office for vendor pick up and delivery throughout the day. Service time varies but is typically completed the same day; however, same day returns are not guaranteed.

All maintenance and repairs over $300 must be approved in advance. It is the vendor's responsibility to contact DAS Fleet Services at 515-281-3162 for approval.
