Common questions about heavy-duty fleet repair
What does mobile heavy-duty truck repair cost in Southern California?
A mobile call is billed as travel, diagnostic and labour time plus parts, and mobile rates sit above shop rates because the shop comes to you. What usually decides the real cost is diagnostic accuracy — a fault found correctly the first time is far cheaper than three parts swapped on a guess. Call for a firm quote on your job.
Do you run real OEM diagnostics or just read fault codes?
Real OEM software. Reading a code off a generic scanner tells you a circuit is unhappy; OEM-level diagnostics on Cummins and Detroit Diesel let us interrogate the ECM, run tests, reflash where needed and pinpoint the actual fault. That difference is why our technicians spent seventeen years inside Freightliner and International dealerships.
Can you service CNG and LNG heavy-duty engines?
Yes, and very few shops in Los Angeles can. We service Cummins natural-gas platforms used in refuse trucks, municipal heavy-duty fleets and transit and school buses. If you run alternative fuel and have been told to take it to a dealer, talk to us first.
Do you handle DPF and aftertreatment problems?
Yes. We run forced regens, diagnose and repair the sensors and wiring behind persistent regen faults, and deal with the emissions-system problems that put a truck into derate. Recurring regens are usually a symptom of something upstream rather than a filter that simply needs cleaning.
How long have you been doing this?
The business has served Greater Los Angeles since 2013, and the team behind it carries roughly thirty years in truck repair — including seventeen years working inside Freightliner and International OEM dealerships before starting the company.
