What I can help with

  • 🚨 Emergency repair

    Stuck on the road, in a parking lot or at home? Call and I'll come fix it where the car is.

  • Car won't start

    Dead battery, bad starter, or a clicking sound when you turn the key.

  • Battery keeps dying

    I find what is draining it so you stop needing jump starts.

  • Warning lights

    Check engine and other dashboard lights, explained and fixed.

  • Alternator and battery replacement

    Done at your home, usually in the same visit.

  • Electrical problems

    Lights, windows, locks or anything else that stopped working.

  • Engine running rough

    Shaking, stalling or loss of power, tested and repaired.

  • Overheating and leaks

    Radiators, hoses and coolant leaks.

  • Used car check-up

    Buying a used car? I'll look it over before you pay.

About me

Real shop experience, without shop prices

I'm Aris. Before starting Sigma Auto Works, I spent years working in and managing busy auto repair shops in Los Angeles and the Bay Area. I've seen how repairs get priced, where the extra costs come from, and how much trust matters.

Today I bring that same shop-level know-how and professional diagnostic equipment straight to your driveway, without the shop overhead.

— Aris, owner

  • I find the real problem first, so you don't pay for parts you don't need.
