Claim This BusinessDiesel Guru's operates as a diesel engine repair specialist serving the Metro Atlanta region from two conveniently located facilities. The business maintains round-the-clock availability for roadside assistance while standard shop hours run Monday through Friday from 8 AM to 5 PM. With 243 customer reviews on record, the company has accumulated a 4.4-star average rating, indicating substantial market presence in the competitive diesel repair sector. The operation serves commercial trucking fleets and individual vehicle owners across Atlanta and surrounding communities including Fairburn, providing mobile services that bring certified technicians directly to stranded vehicles.
The company distinguishes itself through comprehensive in-house capabilities that eliminate the need for multiple vendor referrals. Their technicians perform electrical and computer diagnostics using high-tech equipment, ensuring accurate problem identification before any repair begins. Beyond standard engine work, the shop handles specialized services including DPF cleaning for improved performance and reduced maintenance costs, precision welding and custom metal fabrication, air brake system repairs, and complete driveline system service for light, medium, and heavy-duty commercial vehicles. They also address the often-overlooked HVAC systems in semi-trailers, repairing air conditioning components that keep cargo and drivers comfortable during Georgia's extreme temperatures.
Customer feedback reveals a mixed service record worth potential clients' attention. Among positive experiences, clients have praised the team's diagnostic skill and responsive emergency service during breakdown situations. However, a detailed one-star review documents a significant dispute involving engine replacement work that was never completed, with the reviewer claiming unauthorized charges appeared on their credit card and the promised remanufactured engine never arrived. This review specifically names the owner, Javontez Burnette, and the facility on Fleetwood Drive, serving as a cautionary data point for prospective customers considering major engine or drivetrain work.
Of 243 reviews, the aggregate 4.4-star rating reflects predominantly satisfied customers, though the single detailed review on record describes a significant dispute involving incomplete engine work and unauthorized charges. Positive reviewers frequently cite the convenience of mobile service and diagnostic accuracy, while negative feedback centers on communication during complex repairs and billing transparency.
