Your Mobile Diesel Mechanic in Portland
Portland's port, rail yards and I-5 / I-84 corridors make it the Northwest's major freight gateway.
Our mobile diesel mechanics serve Portland and the rest of Multnomah County, covering I-5, I-84, I-205 and the surrounding roads. We handle roadside breakdowns, truck stop repairs and onsite fleet maintenance at yards and distribution centers.
Heavy freight traffic, wet weather and winter conditions — including chain controls on the Siskiyou Pass — make breakdowns more challenging. We check road conditions and safety before dispatching and keep you updated on your ETA.
Common Portland Breakdowns We Fix
- Tire failures and rim replacement
- Air leaks and air brake repairs
- Cold-weather battery and starting problems
- DEF faults and derates
- Trailer lighting and air line repairs

Why Oregon Truckers Trust Us
“We use Rapid Truck Repair regularly for road calls, and I honestly don't know what we'd do without them sometimes. They've saved us more headaches than I can count and have proven time and time again that they're people we can count on. They do great work, they're honest, and they genuinely care about taking care of their customers. A huge shoutout to Macie! She's always incredibly helpful, easy to communicate with, and willing to go the extra mile.”
“I've been in the trucking industry for many years, and this is by far the best truck service I've ever received. They were quick to respond and handled everything efficiently. On top of that, their pricing was extremely reasonable which is a huge relief when you're in a bind. I'm definitely sticking with them for any future truck service needs. Highly recommend!”
“I've had Rapid Truck Repair help me out a couple of times during the night with our semi-trucks, and they've always been on time. We broke down in Weed, CA and they went out of their way next day to make sure we had the right parts to get our truck fixed, which was super important for keeping our deliveries on schedule. Really appreciate their quick and reliable service.”
“My EGR pipe completely cracked off on my T680 with an X15 engine. I was in Yreka, California, and it was the weekend. They came out, removed my parts, went to the Kenworth dealer, picked up all the original hoses and clamps, completed the repairs, and got me home. Can't thank them enough!”
