Best Truck Repair Shop in Dallas, TX
The best truck repair shop in Dallas depends on what has stopped your truck and what it takes to get it working again. A roadside breakdown, a cooling-system problem, and scheduled fleet maintenance call for different capabilities. Use the rankings above as a starting point, then compare each shop’s listed services, review history, and answers to a few practical questions before booking.
How we picked the best truck repair shop in Dallas
The BizzFactor Score combines Google ratings, review volume and recency, customer sentiment, years in business, and verified credentials. In plain terms, it looks beyond the star average to consider how much feedback supports it, how recent that feedback is, and the business’s track record. A perfect rating alone does not automatically put a shop first.
A-Z Complete Truck & Trailer Repair leads with a BizzFactor Score of 70.85, followed by Salazar Semi-Truck Repair Inc at 68.4 and Integrity Mobile Truck Maintenance and Repair at 62.25. Licensing and insurance are not confirmed for any business listed here, and BBB information is unavailable. Treat those items as checks to make yourself, not assurances that come with a ranking.

What to look for when hiring
Start with equipment fit rather than the highest rating. Give the shop your truck make, engine, symptoms, warning lights, and whether a trailer or refrigeration unit is involved. Ask whether the technician handles that exact system and has the diagnostic equipment needed for it.
Decide whether you need roadside help or a shop appointment. Mobile service may help with some tire, battery, and diagnostic needs, but ask whether your particular repair can be completed where the truck sits. Confirm the service location, expected arrival window, and what happens if towing or shop work becomes necessary.
Look for a clear diagnostic process and a written estimate separating labor, parts, and additional charges. Ask how the shop handles approval when testing uncovers more work, and whether it provides a repair warranty in writing. For fleet maintenance, request an itemized service record you can keep with the vehicle’s maintenance history.
Questions to ask before you book
“Have you repaired this truck make, engine, and fault before?” Share the model, symptoms, and any fault codes so the shop can assess whether its technician and equipment are a match.
“Can you come to the truck, and when could a technician actually start?” Confirm both the arrival estimate and whether the likely repair can be completed roadside rather than assuming mobile service covers everything.
“What charges apply before repairs begin?” Ask about diagnostic time, mobile call-out charges, mileage, after-hours charges, and towing arrangements so you can compare quotes on the same basis.
“Will you send an itemized estimate and get approval before adding work?” Have the shop explain which repairs address the immediate fault and which are maintenance recommendations that can be considered separately.
“Can you confirm your insurance and any credentials relevant to this job?” Licensing and insurance verification remain open checks for these listings, so ask for documentation rather than relying on a rating or business name.
“What is the realistic completion window, and what warranty covers the repair?” Ask whether needed parts are available and whether warranty terms address both parts and labor, including how follow-up problems are handled.
Red flags to avoid
Be cautious when a shop recommends expensive parts without explaining its testing or findings. A fault code can be a starting point for diagnosis, not a complete repair plan by itself. Ask what evidence supports the proposed work before authorizing replacement.
Vague estimates and unclear approval rules can make it difficult to control the bill. Get the scope and charges in writing, including how additional work will be authorized. Pressure to approve unrelated repairs immediately is a reason to slow down and ask for an explanation.
Do not confuse a strong rating with proof of insurance, credentials, or around-the-clock availability. Even a business name containing “24/7” should prompt a question about current coverage and response time. Hesitation to document qualifications, explain warranty terms, or provide an itemized invoice is worth taking seriously.
