Seasonal Care Advantage

A seasonal maintenance package built around what Southern California driving does to a car — ask the service desk for current inclusions and pricing.

Available for a limited time. See shop for details. Cannot be combined with other offers.

Core Services

Three systems. One standard.

Every car that comes through our door — Tesla, gas, diesel or hybrid — is treated to the same sequence: scan first, diagnose the fault to its source, then repair with factory-grade parts. Nothing is opened before you say yes.

Advanced Diagnostics

Factory scan tools. Real fault tracing. No guesswork, no pre-emptive parts swaps.

We run Mercedes XENTRY and Porsche PIWIS III alongside multi-make scan platforms — capturing live data, logging fault codes, and photographing every anomaly before we write a quote. The diagnostic report is yours to keep. Check-engine lights, ABS faults, airbag warnings, traction control errors and CAN-bus irregularities are all within scope. Every car arrives on the scanner before it arrives on a lift.

Engine & Powertrain

Petrol, diesel, hybrid and electric drive systems — repaired with OEM parts.

From turbocharged European engines and diesel powertrains to Tesla drive-unit mounts and hybrid systems, our technicians work across the full range of modern powertrains. Transmission service, valve cover gasket replacement, cooling system overhaul and oil leak repair are among the most common jobs through our bays — all backed by the same two-year warranty.

Electrical Systems

CAN-bus repair, MBUX and COMAND service, battery registration, driver-assistance calibration.

Modern European and EV electrical architecture is layered — multiple control modules, high-voltage circuits, and software-dependent systems that fail silently. We handle CAN-bus fault tracing, MBUX and COMAND infotainment updates, 48V mild-hybrid diagnostics, battery replacement with proper ECU registration, and driver-assistance recalibration after windshield or sensor work.

Where The Work Happens

Every car starts on the scanner.

The real work isn't the teardown — it's finding the fault. We trace every system down to the smallest seal before a wrench ever touches the car. Diagnose it right, and the repair follows. Some failures arrive on schedule; we replace those parts before they fail, and leave the sound ones alone. Guessing costs more than knowing.

Eleven dedicated bays, eight senior technicians, and factory-level tooling for Tesla, Mercedes-Benz, Porsche and beyond mean a car doesn't wait in line behind guesswork. It waits for a proper answer.

20+ cars serviced daily · 500+ repaired monthly

The Standard

What every repair includes.

Three commitments apply to every car that leaves our bays, from a same-day brake job to a full powertrain rebuild.

2-Year / 20,000-Mile Warranty

Every repair is covered — parts and labor — for two years or 20,000 miles, whichever comes first. If a related issue recurs, we stand behind it.

Authorisation Before Action

Nothing is opened, ordered or replaced until you have reviewed our findings and said yes. The itemised quote comes before the invoice, never after.

Diagnosis Before Opinion

Every car goes on the scan tool first. We trace the fault to its source before quoting a single part — no pre-emptive swaps, no guesswork billed as repair.

Transparent pricing. No surprises.

Every job is quoted individually after diagnosis, and nothing is ordered or opened until you have approved the figure in writing. Walk-in services such as brakes, alignment and maintenance are priced upfront; for complex diagnosis or powertrain work, the car stays overnight and the report comes first.

No parts ordered without owner authorisation
2-year / 20,000-mile warranty included in every quoted price

Bilingual service desk with prompt replies

The Protocol

Six steps, in this order.

The sequence never changes, whether it's a cabin filter or a control-arm rebuild.

Drop-Off

You describe the symptom in your own words — we write it down verbatim before anyone touches the car. Walk-ins welcome for maintenance, brakes and alignment; complex diagnosis and powertrain work should be booked ahead so the car can stay overnight if needed.

Diagnose

Every vehicle goes on the scan tool first: module scan, live data capture and a physical inspection. We photograph everything we question and compile a written diagnostic report — findings before invoice.

Authorise

We present the findings and the quote before ordering a single part. Nothing is opened, replaced or scheduled until you have reviewed the report and said yes.

Execute

Repairs are carried out by senior technicians using OEM or factory-supplier parts. Towing referrals and loaner coordination can be arranged for vehicles that cannot be driven in.

Road Test

Every completed vehicle goes on a road test before it goes back to you — driven until the numbers and the feel agree, regardless of the time it takes.

Deliver

The car is returned washed, with printed repair documentation and warranty paperwork. Your service record is kept on file for every future visit.

Frequently asked

Does a Tesla really need maintenance?

Yes — just not the same maintenance as a gas car. Tesla's own owner's manual calls for tire rotation every 6,250 miles, cabin air filter replacement every 2 years, HEPA filter replacement every 3 years on cars that have one, and a brake fluid check every 4 years. Instant torque and a heavy battery also wear tires, suspension bushings and alignment sooner than most owners expect.

Which makes do you work on?

Tesla, Mercedes-Benz, BMW, Audi, Porsche, Range Rover, Bentley, Rolls-Royce, Aston Martin, Ferrari, Lamborghini, McLaren and more — plus everyday makes like Toyota, Lexus, Honda, Acura, Ford and Mazda for walk-in service, brakes and alignment. Don't see your make listed? We still fix it.

Do I need an appointment?

Not for maintenance, brakes or alignment — walk in, same day, no appointment needed. For diagnosis, fault-finding, engine and transmission work, or a pre-purchase inspection, book ahead so the car can stay overnight if required.

How do I know when my brakes need service?

Squealing, grinding, a soft or spongy pedal, or the car pulling to one side under braking are the usual signs. We inspect pad thickness, rotor condition and fluid on every visit and include it in the written report before quoting.

How often should I service my car?

Regular Service (A) runs every 1 year / 10,000 miles; Intermediate Service (B) every 2 years / 20,000 miles, adding a full brake fluid change and cabin filter. EVs follow a lighter interval built around tires, filters and thermal system checks.

Why is regular maintenance important?

Some failures arrive on schedule — bushings, filters, fluids. Replacing those on time, and leaving the sound parts alone, is cheaper than waiting for a breakdown and keeps the two-year warranty meaningful on everything we've already repaired.

In Their Words

Trusted by luxury and EV owners across Southern California.

"Brought my Model Y in for an alignment and left with a full printout and an explanation I actually understood. They put it on the scanner first, found an alignment-related tire wear pattern I hadn't noticed, and fixed it in one visit. No upsell, no drama."

Kevin L.

Chino Hills, CA

"My S580 was dropping one corner overnight — AIRMATIC fault. The dealer wanted three weeks and a very large deposit. WSC diagnosed it the same day I called, ordered the part, and had it back to me on the road in two days. Covered under their two-year warranty."

Michelle T.

Diamond Bar, CA

"They worked on my 2019 Porsche Cayenne — oil leak from the valve cover, plus a steering pull I'd been ignoring. They sent me photos of everything before touching it, quoted it before ordering parts, and the repair was done right the first time. This is the shop I've been looking for."

Service Area

Southern California, covered.

WSC Auto Center sits at 13082 Central Ave in Chino, within easy reach of the Inland Empire, the San Gabriel Valley and the northern edge of Orange County. Owners routinely drive in from Chino Hills, Diamond Bar and Rancho Cucamonga for scheduled maintenance, and from further out — Corona, Eastvale, West Covina, Glendora — for the diagnostic work that dealers quote weeks out.

Towing referrals are available for vehicles that can't be driven in, and loaner coordination can be arranged for overnight diagnostic and powertrain jobs. Whichever city you're calling from, the same protocol applies: scan first, quote in writing, repair with OEM parts, and a two-year, 20,000-mile warranty behind it.
