Symptom
Shakes when braking
Steering wheel shake, brake pedal pulsation, or front-end vibration under braking usually points to rotor, pad, or suspension-related brake issues.
Symptom
Car won't start
No-crank and no-start complaints usually resolve into battery, starter, alternator, crank sensor, or fuel-delivery diagnosis.
Symptom
Engine overheating
Overheating and coolant-temperature complaints usually map to thermostat, radiator, water pump, coolant flow, or fan-system faults.
Symptom
Battery light on
A battery or charging warning light usually means alternator output, battery health, belt drive, or cable/ground faults need to be checked first.
Symptom
Rough idle
Rough idle often traces back to ignition, air metering, vacuum leaks, or timing-related faults before it becomes a full misfire complaint.
Symptom
Steers to the right
Steering pull and drift complaints commonly involve alignment, tires, tie rods, ball joints, wheel bearings, or brake drag.
Symptom
Squeaky brakes
Brake squeal and brake-noise complaints usually resolve into pad wear, rotor condition, hardware, or brake dust contamination.
Symptom
Transmission slipping
Slipping, flare, or delayed-shift complaints usually need fluid condition, hydraulic pressure, and internal wear checks before major replacement.
