I stopped in on the afternoon of 5/19/2025 with brakes starting to grind, they were full until Friday but when Michelle found out I have a mountain drive she went and talked to the mechanics, and they fit me in that very afternoon. What service! I will recommend their work to anyone. Thank you

It isn’t easy keeping your fleet or commercial trucks up and running. At Repair Masters Automotive LLC in Boulder & Louisville, CO, we’re here to help. Fleet and commercial vehicles log a lot of miles, and a lot of hours - as a result, even the most reliable components need to be serviced occasionally. On an ordinary diesel, an injection pump may last the entire life of the engine itself. On vehicles that work harder than anything else on the road, this isn’t always the case. 

Increasingly, technology in automobiles is becoming more sophisticated, and more and more systems have become reliant on electronic control modules to operate. At Repair Masters Automotive LLC in Boulder & Louisville, CO, we have the trained technicians and the equipment necessary to deal with issues that arise as a result of these components.

While most fleet vehicles are chosen for their reliability, low maintenance, and durability, sometimes maintaining several of them at a time can become overwhelming. Just keeping up with the maintenance schedule alone is a task and then to ensure you keep your scheduled routes for those fleet vehicles is another task in itself. Let Repair Masters Automotive LLC in Boulder & Louisville put your mind at ease, with our fleet maintenance programs for any and all fleet vehicles. We will take the stress from your business fleet program and get your fleet trucks and fleet cars running at optimum performance with a routine that works for your business that often REDUCES costs!

At Repair Masters Automotive LLC in Boulder & Louisville, CO, we know how annoying a faulty fuel gauge can be. Never knowing how much gas you have in your car, truck, or SUV, and constantly running the risk of stranding yourself on the road somewhere, takes its toll after a while. Luckily, we can fix that.

Transmissions, while generally durable, can be highly complicated devices. For this reason, they are also expensive to replace, and maintaining one will save you a lot of headache and money in the future. This article from Repair Masters Automotive LLC in Boulder & Louisville, CO discusses how your driving habits affect your transmission. While automatic transmissions are by far the most common, there are still a considerable number of manual transmissions on the road, so this article covers both.
