Severity:

Group 01

Dashboard warning lights.

If a light is flashing, treat it as urgent. Solid means schedule, not panic.

Check engine light, solid

Schedule this week

Dozens of possible causes. The code narrows it; real diagnosis confirms it.

Battery / charging system

Schedule this week

Alternator, battery, or wiring. Most batteries die because of charging issues, not age.

ABS / brake light

Schedule this week

ABS sensor, low brake fluid, or worn pads triggering a sensor.

Tire pressure (TPMS) light

Inspect at next visit

Cold-morning false alarm, slow leak, or a sensor whose battery has died.

Temperature gauge in the red

Stop driving

Coolant level, thermostat, water pump, or radiator. Pull over immediately.

Oil pressure light

Stop driving

Low oil, bad sensor, or pump failure. Stop driving until you have an answer.

Group 02

Sounds your car shouldn't make.

Most car problems announce themselves before they fail. Listen, then come in.

Squealing when you brake

Schedule this week

Wear-indicator tab on the brake pad. Schedule within the month.

Grinding or metal-on-metal braking

Schedule this week

Pads worn through, scoring the rotor. This week, not next.

Engine knock or tick

Schedule this week

Lifter, timing component, low oil, or pre-ignition. Diagnose before driving far.

Whine that changes with vehicle speed

Schedule this week

Wheel bearing or differential. Worth a road test diagnosis.

Squeal when AC turns on

Schedule this week

AC compressor pulley or serpentine belt.

Click-click-click when starting

Schedule this week

Weak battery or starter solenoid.

Group 03

Smells from the cabin or hood.

Smells almost always mean a leak. The leak is the easy clue.

Sweet, syrupy smell

Schedule this week

Coolant leak. Could be a hose, radiator, or heater core.

Burning rubber

Schedule this week

Belt slipping, hose touching exhaust, or a frozen pulley.

Hot oil / acrid smell after driving

Schedule this week

Oil leak hitting the exhaust. Find the leak before it grows.

Strong gasoline smell

Stop driving

Fuel leak, leaking injector seal, or an evap-system fault.

Sulfur (rotten egg)

Schedule this week

Catalytic converter or running rich. Texas inspection will fail.

Electrical / burning plastic

Stop driving

Wiring overheating somewhere. Stop driving.

Group 04

How the car feels.

Vibration, pulling, soft pedals, the way the car drives tells the truth.

Vibration through steering at highway speed

Schedule this week

Tire balance, alignment, or a bent rim.

Car pulls to one side

Schedule this week

Alignment, tire pressure, or a stuck brake caliper.

Brake pedal goes soft or sinks

Stop driving

Air in the lines, leak, or master cylinder. Do not drive.

Pedal pulses under braking

Schedule this week

Warped rotors. Sometimes resurfaced, often replaced.

Hesitation on acceleration

Schedule this week

Fuel system, ignition, or a sensor going out of spec.

Steering goes heavy

Schedule this week

Power-steering fluid leak or pump failure.

Group 05

How the car behaves.

Starting, idling, stalling, the car's behavior is data.

Slow crank in the morning

Schedule this week

Battery (3+ years old in Texas heat is normal lifespan).

No crank, just clicking

Stop driving

Battery dead, starter solenoid, or wiring at the battery terminals.

Engine stalls at idle

Schedule this week

Idle-air control, vacuum leak, fuel pump, or fueling problem.

Rough idle

Schedule this week

Misfire, vacuum leak, or fouled spark plugs.

Mileage suddenly worse

Schedule this week

Oxygen sensor, fuel-system fault, low tire pressure, or dirty MAF sensor.

AC blows warm

Schedule this week

Refrigerant leak, compressor, or condenser. Texas heat exposes it fast.
