Urgent symptoms: fluid leaks, tire problems and warnings

A tire blowout, low oil pressure, slipping transmission or overheating can require an immediate safe stop. Choose the relevant owner-safety research before starting vehicle-specific diagnosis.

Tires · NHTSA guidance

Flat tire / blowout

Stabilize safely, identify when a tire needs professional assessment, and confirm the vehicle's placard.

Engine oil · owner research cluster

Oil leak / low pressure

Start with urgent low-pressure warnings, then compare small leaks, valve-cover, oil-pan, post-service and cost questions.

Gearbox · fluid-loss research

Transmission fluid leak

Fluid identification, dangerous shifting symptoms, post-service checks and a diagnosis-first estimate.

Cooling · manufacturer warnings

Coolant leak / overheating

Separate A/C water from coolant, observe the reservoir cold, and respect stop-driving warning signs.
