The commercial trucking industry is facing a quiet crisis in the service bays.
Nearly two-thirds of heavy-duty fleet maintenance shops are understaffed due to the ongoing diesel tech shortage.
For fleet managers that maintain their own trucks, fewer hands on the wrenches quickly translates to longer wait times, deferred preventive maintenance, and immobilizing vehicle downtime that threatens the bottom line.
We feel this pain too. That’s why we’ve talked with our service managers and created a practical, survival blueprint for fleet operations looking to keep their trucks running smoothly during a tech shortage. By exploring high-yield maintenance strategies, remote diagnostic tools, external mobile maintenance partnerships, and intentional shop floor culture shifts, you will learn how to optimize your current team’s efficiency, add additional assets and protect your fleet from extended operational downtime.
Emphasize the Importance of the PM
Preventive maintenance is always important, but when your shop is lean, this seemingly simple task becomes a key maintenance strategy. When your trucks are properly maintained, they have less chance of issues down the road, causing longer downtime and tying up precious tech time and can save money in the long run.
- Target an 80% preventive and 20% corrective maintenance ratio. Every 10-point gain in PM compliance cuts overall fleet maintenance costs by up to 8%.
- Use fleet management software to trigger service intervals based on exact mileage or engine hours rather than manual guesswork.
- Finding and fixing minor component wear early prevents catastrophic road failures that require scarce emergency labor, extend downtime and increase costs.
Leverage Telematics and Remote Diagnostics
Today’s trucks are basically massive computers on wheels. Everything they do is captured and recorded. Use this valuable information to your advantage.
- Cut diagnostic time by leveraging fleet data. From simple to complex fault codes, remote diagnostics let you triage alerts before the vehicle ever hits the shop.
- Train your tech team to focus on mission-critical fault codes. Many times, codes are triggered when minor sensor issues arise – these can be managed during scheduled PMs.
- Knowing what’s coming ahead of time can help you better prepare to maximize shop efficiency. Once you know the issue, you can ensure parts are ordered/in place, and you can schedule the right tech for the job.
Simplify Communications
Whether you are a single shop with a few techs or a multi-location operation with many techs, giving them a simple tool they can use for internal tech support and open discussions is always helpful. They can learn from each other and teach each other, saving on productivity time trying to figure out situations that may be new to one tech but already solved by another. Simple instant messaging tools and aps work great, or your organization may have other ways to open communications for the tech team.
Supplement with Trusted Outside Partners
While you may try to manage all maintenance internally, there are always needs outside the norm. One maintenance strategy that helps with a tech shortage is to have a reliable partner for the jobs that are beyond your capacity.
- Partner with our Mobile Fleet Services team for an extra set of hands. We can come right to your shop or handle road calls when needed.
- Some jobs may be outside your tech team’s capability. Bergey’s Truck Centers have knowledgeable OEM-certified technicians, and the diagnostic tools, systems and parts to get the job done quickly, allowing your team to stay focused on other projects.
- Any make, any model. When you need extra hands, we got you covered:
- 15 Full-service locations
- 6 Parts stores
- Online parts shop
- Tire sales and service
- Collision repair
Foucs on Technician Retention
When shops are short-staffed, burnout accelerates. Replacing a skilled diesel mechanic can cost nearly twice their annual salary. But it’s important to realize that true retention isn’t just about the paycheck, it’s about making your team feel seen, heard, and respected.
- Your techs are many times the “unsung heroes” in your operation. Make it a point to shift your culture and regularly acknowledge their efforts, especially during a tech shortage.
- Hold regular meetings on company time to allow for sharing of best practices, point out stellar safety efforts and yes, let them vent a little. Slowly, this venting will lessen because they are being heard.
- Consider work schedule flexibility as a maintenance strategy. Today’s new hires want more flexibility to match needed work life balance. Whether that’s 4×10-hour shifts or 3×12-hour shifts or whatever you can come up with that work for both the company and the technician goes a long way in keeping techs happy.
- Celebrate Tech Appreciation Week (Sept 20-26, 2026). There are many ways you can show your appreciation and help drive professionalism and positivity.
- Hand out high-quality tool allowances, premium work socks, or gift cards to heavy-duty boot retailers. Upgrading the tools they rely on daily shows respect for their labors.
- Expand the kudos beyond the shop. Include drivers or corporate staff by having them write individualized thank-you notes. Pointing out specifics for difficult diagnostic jobs or going above and beyond shows that others that depend on them acknowledge their efforts, and the personalization keeps it authentic rather than corporate.
- Bring in the Food Trucks! Skip the cold pizza. Who doesn’t love a local food truck pulling into the yard, giving the team a hot, delicious meal without having to scramble during their break. This time also allows for comradery and much needed downtime.
- Introduce a structured recognition system—like a pin, patch or even a decal for their toolchest. You can customize this maintenance strategy to your company, or you can find online programs geared toward technical expertise.
