These three departments hold the four-figure repairs, and all three announce themselves early. Oil weeping from a valve cover gasket, a chain rattle on a cold start, coolant vanishing with no puddle underneath — engine territory.

→ European engine repair

Automatics tell on themselves differently. Shudder under light throttle around 20 mph, in a ZF 8-speed or a DSG, points at fluid, a valve body or a mechatronic unit — and none of those three improve with time.

→ transmission repair and diagnosis

Manuals are rare now. But a pedal that grabs high in its travel, or slips while climbing Summerlin Parkway, is still a clutch job.

→ clutch replacement

You feel these long before a warning light shows up. Pulsing at 45 mph on the descent back from Red Rock usually means heat-warped rotors rather than air in the lines.

→ brake repair for European cars

Air suspension is the desert's other victim. Any Mercedes or Range Rover that settles onto one corner overnight has a leaking air strut, and sun-baked rubber gives up years before the odometer says it should.

→ suspension and air strut service

Then there are wheels. Low-profile summer tires on 19s and 20s find every seam on Spring Mountain Road, and a bent rim shows up as a vibration that arrives at one steady speed and vanishes above it.

→ tire and wheel services

Two departments, one enemy. Heat. A/C failures here cluster around leaking O-rings, a condenser packed with dust, and a blower motor that has run on high since May.

→ auto A/C repair

Cooling systems fail on the plastic. Thermostat housings crack, expansion tanks split at the seam, and a water pump impeller shears while you sit in traffic on Rainbow watching the gauge climb.

→ radiator and cooling system repair

The number on the bottle is the smaller half of the spec. An engine asking for BMW LL-01 or VW 504 00 needs that approval printed on the container, because the approval covers the additive package the timing chain and turbo bearings actually depend on. Buy the approval.

→ full-service oil change

Tune-up work is the ignition and air side — plugs, coils, filters. On a direct-injection turbo engine the plug interval lands somewhere between 30,000 and 60,000 miles depending on the engine.
