M&M RoadService LLC

M&M RoadService LLC is a mobile diesel engine repair service serving Riverside and the surrounding desert corridor. With a 4.9-star rating from 61 reviews, the company has built a reputation for responding to stranded truckers on remote highways when breakdowns occur in harsh conditions. The business operates as a mobile service, meaning repairs happen at the roadside rather than at a fixed shop location, minimizing downtime for commercial drivers and transport companies.

What distinguishes M&M RoadService is their willingness and ability to work overnight hours to get customers back on the road. Multiple reviewers describe scenarios where technicians arrived during late-night hours in remote desert locations, diagnosed problems on the spot, and somehow procured necessary parts even at 2 AM. This level of availability and resourcefulness proves valuable for truckers facing delays in areas far from traditional repair facilities.

Reviewers consistently mention specific technicians who handled their emergencies. Malachi was praised for arriving quickly on Highway 95 around midnight, diagnosing a coolant leak, and obtaining the exact part needed at that late hour. Matthew was called out for a blown radiator on Route 40, keeping customers informed throughout the repair process. One reviewer described the team as going way beyond what was expected to get trucks running again faster than anticipated.
