Your car talks. These ten sounds, smells and lights all mean the same thing: book now.

One to three — sounds: squealing brakes (wear indicators), grinding that changes with speed (bearings or brakes), and a new exhaust rumble (leak or broken hanger). New noises are always news.

Four to six — feels: pulling to one side (alignment or brakes), vibration at highway speed (balance or suspension), and a soft or sinking pedal (hydraulics — stop driving).

Seven to ten — sights and smells: any dashboard warning light that stays on, fluid spots where you park, sweet maple-syrup smell (coolant leak), and rotten-egg exhaust (catalyst or fuel mixture).

Two or more at once? Skip the internet diagnosis and get a 40-point inspection — it is free with any Crank service and takes under an hour.

Cars rarely fail without warning. They whisper for months, then shout once. Listen early and the fix is usually small.
