What We Do

The Service Index

From routine maintenance to serious engine work, Laguna Viejo Auto handles it all with straight talk and fair pricing. We fix what's actually broken and tell you plainly what can wait — every repair backed by a written, pre-approved estimate.

Our Check-Engine & Diagnostics service goes far beyond reading a code — we interpret what that code means for your specific vehicle so you're never throwing parts at a problem hoping something sticks. When you understand the actual failure, you spend money once instead of three times.

Brake Repair & Service covers pads, rotors, calipers, fluid flushes, and everything in between, always with a visual walkthrough of the wear so you can see exactly why a part is being replaced. For bigger jobs, our Engine Repair and Transmission Service teams tackle timing components, gaskets, seals, fluid services, and shift issues — while our A/C & Heating repairs keep your cabin comfortable through every Southern California summer.

Check-Engine & Diagnostics

We find the real cause — not just the code.

That little light can mean a $20 sensor or a bigger issue, so we don't guess. Our techs read the codes, test the systems, and trace the problem to its source, then explain exactly what's wrong and what it'll cost before any work starts.

Brake Repair & Service

Stop confidently with brakes done right.

Squealing, grinding, or a soft pedal shouldn't be ignored. We inspect pads, rotors, calipers, and lines, then tell you what actually needs replacing — and what can wait. No scare tactics, just safe brakes.

Oil Changes & Maintenance

Keep it running with scheduled upkeep.

Routine maintenance is the cheapest way to avoid big repairs. We follow your factory schedule, change your oil and filters, and give every car a multi-point once-over so small issues get caught early.

Engine Repair

From misfires to major work, done honestly.

Whether it's a rough idle, a leak, or a bigger failure, we diagnose the engine first and lay out your options clearly. We'll tell you when a repair makes sense and when it doesn't.

Transmission Service

Smooth shifting without the sticker shock.

Slipping, hard shifts, or delayed engagement often start small. We service fluids, diagnose issues, and handle repairs — being upfront about whether a service or a rebuild is the right call.

Automatic & manual service

A/C & Heating

Cold air when Southern California heats up.

A weak A/C is more than uncomfortable in Mission Viejo summers. We test the system, find leaks, recharge refrigerant, and repair compressors so your cabin stays cool and your defroster works.
