Claim Your Free PageDiesel Master Repairs operates as a specialized truck repair facility in Elizabeth, New Jersey, serving communities throughout Union County and the greater Newark metro area. The shop maintains a perfect 5.0-star rating across 16 client reviews, reflecting consistent quality in diagnostics and repairs for commercial box trucks, delivery vehicles, and fleet equipment. Open Monday through Friday from 8 AM to 6 PM, with Saturday hours until 2 PM, the facility provides accessible service scheduling for owner-operators and business fleets alike.
Owner Andres leads the service team with a reputation for accurate diagnostics and fair pricing, a combination highlighted repeatedly in client feedback. The shop distinguishes itself through honest assessments that prevent unnecessary repairs, evidenced by cases where customers arrived expecting major engine work but left with targeted fixes instead. This approach saves vehicle owners substantial labor costs while delivering lasting solutions.
Customer narratives from Mason J and Jonathan Farkash illustrate the shops capability with complex repairs. Mason brought a box truck displaying multiple issues including AC failure, a compromised oil pan, and brake system problems, all addressed in a single visit at reasonable cost. Jonathan described arriving after another shop recommended a full engine rebuild, only to have Andres identify and correct the specific fault without invasive surgery. Both reviewers emphasize the combination of technical skill and transparent communication that defines the Diesel Master Repairs experience.
All eight published reviews award five stars, with four clients specifically naming Andres as the diagnosing technician. Five reviewers mention cost-related honesty, while three reference the shops ability to resolve issues other shops could not correctly identify. No negative reviews exist in the available sample.
