Why Big D
This is our specialty. We diagnose accurately before recommending repairs, explain what’s actually wrong in plain terms, and back the work with our 24-month / 24,000-mile warranty on parts, labor, and towing. We never run testing without your okay first.
Do you work on electric vehicles?
Yes. We’ve serviced many Teslas, Rivians, and plug-in hybrids — service most independent shops won’t touch.
Can you program modules?
Yes, we do module programming in-house with professional Autel equipment, so you often don’t need the dealer.
Will I be charged just for a diagnosis?
We never run diagnostics or testing without your approval. If you have the repair done with us, the testing fee may be waived.
