Quotes up front, no surprises
Why drivers choose usMost shops sell repairs.
Most shops sell repairs.
We earn your trust.
Owner Nirmal built Shiv Auto Service on one simple idea: treat every car like it's your own, and tell people the truth. That's why so many of our customers come back — and bring their families.
We show you the problem
Nirmal walks you through the actual issue and shares photos of the worn or broken part, so you can see exactly what you're paying for.
Fair, transparent pricing
Clear quotes up front and fair prices on parts and labor. No surprise charges when you come to pick up your car.
Quality parts, real care
We insist on good parts and stand behind the work — because most of our customers come back, and send their friends.
What we do
Full-service repair, done honestly
From a quick oil change to a full transmission rebuild — we handle the work most shops do, and we'll only recommend what your car actually needs.
Oil Change & Maintenance
Routine oil changes, filters, fluids and factory-schedule maintenance to keep your car running clean and reliable.
Engine Repair & Diagnostics
Check-engine light on? We read the codes and pinpoint the real cause — then tell you straight what actually needs fixing.
DPF Cleaning
Diesel Particulate Filter cleaning and regeneration to clear soot buildup, fix limp-mode warnings and keep your diesel running clean — without an expensive filter replacement.
HHO Carbon Cleaning
Hydrogen (HHO) engine carbon cleaning flushes carbon deposits off your valves, injectors and combustion chambers to help restore smoother running and throttle response — no engine teardown.
Brake Repair
Pads, rotors and rotor resurfacing done right. Safe, quiet braking without paying for parts you don't need.
A/C & Heating
Air conditioning installation, recharge and repair, plus heating fixes so your cabin is comfortable year-round.
Steering & Suspension
Shocks, struts, alignment-related steering and suspension work for a smooth, stable, controlled ride.

Transmission service, repair and full replacement — diagnosed honestly so you know exactly where you stand.
Electrical & Batteries
