We are a California licensed STAR certified smog station in Murrieta. That matters because the DMV directs a share of vehicles to a STAR station only — a regular test-only shop legally cannot certify those cars. Bring us your renewal notice and we handle it either way.

Most inspections take about 20–30 minutes. Results are transmitted electronically to the DMV the moment your vehicle passes, so in most cases you can renew online before you leave the parking lot.

A failed smog report is a list of symptoms, not a diagnosis. High NOx, high HC, a monitor that will not set, an EVAP leak, a P0420 catalyst code — each has several possible causes, and replacing a converter to chase a fuel-trim problem is an expensive way to fail twice.

We read the failure report, verify with live data and pinpoint testing, then quote the repair that actually returns the vehicle to spec. Retest here is free after we do the qualifying work.

California does not accept federal EPA converters on most vehicles. We install CARB-compliant units with the required EO number stamped and documented, so the visual portion of your smog inspection passes as cleanly as the tailpipe portion.

Before we quote a converter we confirm the converter is actually the failed part. A converter killed by a misfire or a leaking injector will die again in months if the upstream cause stays.

A smog failure is a diagnostic job, not a parts job. We test, read the readiness monitors and the failure report, then find the actual cause — a lazy oxygen sensor, an EVAP leak, a failing catalytic converter, a misfire, or simply a monitor that never completed a drive cycle.

We handle the inspection and the repair, so you are not bouncing between a test-only station and a repair shop with nobody owning the outcome.

California requires a current brake and lamp inspection certificate for certain registration, salvage, title and out-of-state transactions. We are a licensed official brake and lamp station, so we can inspect, certify and sign you off in the same visit.

We inspect the brake system and every required exterior lamp to DMV standards. If something fails, we can fix it here — pads, rotors, hoses, lines, bulbs, sockets, wiring, switches and more — then issue the certificate without sending you to another shop.

A code tells us which circuit reported a problem, not which part failed. We scan every module, read freeze-frame and live data, then test the circuit — power, ground, signal, mechanical condition — until the fault is proven.

We have extensive experience with Honda, Toyota, Nissan, Subaru and Mazda diagnostics, including VTEC, VVT-i, hybrid inverter, CVT, and direct-injection systems. You get the measured evidence and a written estimate before any repair starts. Diagnostic time is credited toward the repair when we do the work.

On an interference engine a snapped timing belt bends valves and turns a maintenance item into an engine rebuild. Replacement is mileage-based, not symptom-based — there is rarely a warning first. This is especially critical for many Honda, Toyota, Nissan, Subaru and Mazda interference engines.

Because most of the labor is access, we replace the water pump, tensioner, idlers and front seals at the same time. Doing them separately means paying the same labor twice.

Plenty of transmission complaints are not transmission failures. Low or burnt fluid, a failing solenoid, a bad speed sensor, an engine misfire under load — all of them feel like a slipping gearbox from the driver's seat.

We test first. We have extensive experience with Honda, Toyota, Nissan, Subaru and Mazda automatics, CVTs and manual transmissions. If the answer is a clutch or a rebuild, you get a clear written price and a realistic timeline before anything comes apart.

Head gaskets, timing cover leaks, chronic overheating and oil consumption are big-ticket repairs, so the diagnosis has to be right. We pressure test, block test and inspect before quoting, and we photograph what we find.

We are especially experienced with Honda, Toyota, Nissan and Subaru engines — from B-series head gaskets and 2.5L Subaru head gasket service to Toyota 2AZ oil consumption and Nissan VQ timing chains. When an engine is past repair we quote a replacement with a warrantied unit — and if the number is more than the car is worth, we tell you that too.

Brakes are the one repair nobody should be talked into or out of. We measure pad thickness and rotor runout, inspect calipers, hoses, hardware and fluid condition, then show you the numbers next to the manufacturer's minimum spec. If you have life left, we tell you how much.

We service everything from half-ton commuters to three-quarter and one-ton trucks that tow. Loaded trucks eat brakes differently, so we spec pads and rotors for how you actually use the vehicle, not for the cheapest line on the shelf.

Free code readers give you a number, not an answer. P0420 does not mean buy a catalytic converter and P0300 does not mean buy plugs. We scan every module, review freeze-frame data, then test the circuit or component the code is pointing at.

We have deep experience with Japanese makes: Honda VTEC and VCM issues, Toyota VVT-i and AFM sensors, Nissan CVT and VQ timing chains, Subaru misfire and head gasket patterns, and Mazda direct-injection carbon buildup. Diagnostic time is billed honestly at our hourly rate and credited toward the repair when we do the work. You get the fault, the evidence and a written estimate before anything is replaced.

We do not just top off refrigerant and send you out. Low charge means a leak, so we dye and pressure test the system, find where it is losing charge, and repair it before we recharge to the factory weight.

We service R-134a and R-1234yf systems on cars, trucks and work vans, including rear air on vans and SUVs, plus heater cores, blend doors, blower motors and cabin controls.

Most no-start calls are not the battery itself — they are a corroded terminal, a failing alternator, a bad ground or a parasitic draw quietly killing the charge overnight. We load test the whole system before selling you anything.

Trucks with dual batteries need matched, healthy pairs. One weak battery drags the other down and cooks the alternator, so we test and replace them as a set when they need it.

Lighting failures are rarely just a bulb. Brake lamps that stay dead after a new bulb usually point at a switch, socket corrosion, a ground or a body-control fault. We test the circuit, fix the cause and verify every lamp on the vehicle.

We also handle work-truck and towing lighting: 7-pin trailer connectors, brake-controller wiring, bed and utility lighting, light bars, backup lights and DOT clearance lamps on larger trucks.

Overheating destroys head gaskets, injector cups and EGR coolers, and on a truck that is the difference between a hose repair and a teardown. We pressure test the system, check the cap, fan clutch, thermostat and coolant condition, and find the loss before it becomes an engine job.

We service factory-fill coolants to spec — the wrong coolant in a modern engine causes cavitation and liner damage over time.

Exhaust leaks are loud, they smell, and on a truck they cost you turbo response and aftertreatment performance. We repair cracked manifolds, blown gaskets, rusted flanges, broken hangers and failed mufflers on cars, trucks and work vans.

We keep systems street-legal and emissions-compliant — repairs and replacements, not delete work.

An oil change is the best chance anyone gets to catch a problem while it is still small. Every oil service here includes a genuine multi-point inspection — fluids, filters, belts, hoses, brakes and leaks — with photos of anything we flag.

We follow factory maintenance schedules for Honda, Toyota, Nissan, Subaru, Mazda and Lexus 30k, 60k, 90k and 120k intervals, and we tell you what is actually due versus what a quick-lube menu wants to sell you.

Modern tune-ups are about ignition, air, fuel and fluid condition on a schedule your manufacturer already published. We follow your vehicle's factory interval, do the work with quality parts and tell you honestly what is not due yet.

We are especially familiar with Honda, Toyota, Nissan, Subaru and Mazda service schedules, spark intervals, VVT services and fluid specs. Well-maintained engines pass smog. Most emissions failures we see are maintenance failures wearing a check engine light.

Used trucks hide expensive history. We scan every module for stored and history codes, check for deleted or tuned emissions equipment, look for coolant and oil cross-contamination, test injector balance and inspect the frame, brakes, driveline and body before you hand over money.

You get a written report with photos and a realistic estimate of what the vehicle will need in the next twelve months, so you can negotiate or walk away with facts.

We maintain contractor trucks, service vans, box trucks, landscape rigs, tow trucks and small municipal fleets across the Temecula Valley. Fleet accounts get scheduled preventive maintenance, one point of contact, itemized invoicing per unit and priority scheduling when a truck goes down.

Every unit gets its own history file: mileage, services performed, parts used, and what we flagged as coming due. You approve work per unit or set a standing authorization limit so small items never stall a truck for a phone call.
