We'll Keep Your Semi Truck Running

J&A Fleet is a full-service fleet maintenance and repair company serving Northeastern Illinois. No matter what problem you’re having with your diesel or semi truck, we have the tools, expertise, and discernment to fix it. We also offer affordable maintenance plans that prevent costly problems from ever occurring and make the insurance claims process easier if one of your staff runs into trouble on the road. Most companies that work with us do just fine with our $800/month Two-Truck Maintenance Agreement. This bargain service is great because it includes:

We’ll also offer mobile fleet repair services and will take care of roadside repairs within a 75-mile radius. J&A Fleet is here to help even during winter storms and inclement weather! If you bring a diesel or semi truck into the shop, we’ll even drop it off for you once the repairs are done. 

Giving Back to The Southland Community

John and Alex also use J&A Fleet’s Platform to inform and educate locals about important issues and give back to the community whenever they can. If you live in the area, you’ll likely see Alex driving to jobs in The Southland in her pink Breast Cancer Awareness truck and participating in parades and fundraisers. The truck’s hood is also adorned with ribbons to represent all types of cancer to show support for cancer survivors and those who are still fighting.

J&A Fleet also tries to bring attention to other important causes by wrapping their trucks. The team recently added a suicide awareness design to the fleet that broadcasts the suicide hotline number since there have been a lot of deaths in the area recently. This is also a special tribute to veterans and active service members struggling with mental illness. 

J&A Fleet will also be releasing an Autism Awareness truck and a Cub Scout truck soon. It’s J&A Fleet’s mission not only to do good work but use whatever resources we have to do good in the community. That’s why you’ll continue to see more of our wrapped trucks on the roads and at marches in the area.

John & Alex Griffin - Founders

Meet The Founders

John & Alex Griffin

This fleet maintenance and repair duo moved to the area with a dream of helping businesses operate more efficiently with well-maintained fleet vehicles and top-notch repairs. They have achieved that and more, ultimately lowering payroll expenses and making the companies they serve run smoother. Alex and John have dedicated their lives to protecting business’ investments by keeping their vehicles on the road longer. 

Both John and Alex have years of experience in the vehicle repair industry and had a mutual dream of bringing up their children in a place they could play in the front yard without a care in the world. This led them to the Wilmington area where they’re now raising their children and helping businesses run better.
