24/7 Roadside Service

    Mars Diesel was dispatched to me this morning for a roadside breakdown VERY early in the morning. Brett was the technician that came out and even before he arrived he was excellent! He called to confirm my location and the issue and gave a great estimate on arrival time. Once he got there, the issue was fixed within 20 minutes which included the time it took for my truck to rebuild the air it lost. Overall, such a pleasant experience thanks to Brett’s professionalism and knowledge! I always appreciate the mobile repair techs!! Thank you Mars!

    Very nice place with great people. The truck stopped on the road and we had to look for Roadside service. They arrived immediately and tried to help us as much as possible and unfortunately had to tow the truck. They towed the truck to their shop and were able to replace the high pressure fuel pump in a few days. In addition, they allowed us to park our trailer in their parking lot and it stayed there the entire time the truck was being repaired. Very nice clean place with great people. It was nice to work with them. Excellent work.

    The best shop I’ve been to, wish they were located in NC! Truck derated, def light blinking, had so many engine light codes it was embarrassing lol. They got me up and running in a few days. They also took and picked me up from a hotel (didn’t have to do that at all). Thanks Trent! Thanks to all the good people at Mars Diesel! Nice people, reasonable prices and quicker than most shops considering what I got done. Great family business!

    OMG, what can I not say.I would give 10 stars to Mars diesel & Trent their were the best!! Our RV broke down along I-81 and I called numerous RV mobile repair places for assistance none were able to help, either closed, or would only take appointments ( appointments for mobile service???)
    Trent answered and I explained our problem, he said “ no problem and he would have someone there within an hour. Mark arrived , analyzed the problem and had it repaired quickly!
    They guys were a godsend, since none of the “ mobile “ RV repair services could help. Highly recommend these guys for service, emergency or otherwise!
    Thank you again for outstanding customer service!

    Mars Diesel is by far a very reliable shop. The Freightliner Cascadia I run began having DPF issues. After a few hours I was back on the road and headed home. Not only did the correctly diagnos the problem. They agreed to do a temporary fix to get me home. If you are in the area and need help, Mars would definitely be my first shop I would call. In the future I look forward to seeing that pretty blue peterbilt heavy wrecker running up and down the road towing trucks.
