Twelve things worth listening to

Vehicles are honest. Long before something lets go, it taps you on the shoulder: a sound, a light, a feeling through the wheel or the pedal. This guide is the twelve taps we hear about most at the counter, what each one usually means, and how urgent it actually is. Usually is the honest word, because the same sound can have two causes, and the inspection is what settles it.

01

Grinding when you slow down

Right away

Metal on metal at the brakes, which usually means the pads have worn through to the backing. Stopping still works, and every stop is now wearing parts that cost more than pads. This one goes to the front of the line.

02

Squealing that stops when you press the brake

This week

Most brake pads carry a small steel tab that sings on purpose when the pad gets low. It is the polite version of number one, and it is telling you to plan the visit before the grinding starts.

03

A clunk over bumps

This week

Usually a worn ball joint, sway bar link or a loose exhaust hanger. The inspection tells us which, and finding it while it is a clunk keeps it a small repair.

04

A shake at highway speed

This week

A shake in the wheel usually points at balance up front, a shake in the seat points at the rear, and a worn part underneath can look like either. It is measured on the machine rather than argued about.

05

Pulling to one side

This week

Alignment, a dragging brake, or uneven tire pressure. Check the pressures first, because that one is free. If it still pulls, bring it in and we will find which of the other two it is.

06

A slower crank on cold mornings

Plan for it

A battery announcing its retirement, and South Dakota winters move that date up. A load test takes minutes and tells you whether you have another winter in it.

07

A click, then silence, when you turn the key

Right away

The battery, its connections, or the starter. If a jump gets it going, drive it here rather than home, because a battery that took a jump once usually asks again on a colder morning.

08

A sweet smell, or a spot where you park

This week

Sweet smell is coolant, and colored spots on the concrete are the system telling on itself: green or orange is coolant, red brown is often transmission fluid, dark brown is engine oil. A pressure test finds a coolant leak while it is still a hose clamp.

09

A steady check engine light

This week

A steady light with the vehicle running normally usually gives you time to plan the visit. The code stays stored even if the light goes out, so we can read the history either way.

10

A flashing check engine light

Right away

Flashing means a misfire that can damage the catalytic converter, which is one of the most expensive parts on the vehicle. Ease off, and call us before driving it far.

11

A hum or growl that changes when you change lanes

This week

The classic wheel bearing tell. It grows with speed and changes pitch when the load shifts in a lane change. Caught early, it is one corner instead of one corner plus a tow.

12

A soft brake pedal, or one that sinks

Right away

Air or moisture in the brake fluid, a leak, or a master cylinder on its way out. Brakes are the one system where the cautious answer is the only answer: have it looked at before you need them in a hurry.

From the counterThe urgent three are the flashing light, the grinding, and the soft pedal. Everything else on this list rewards a phone call and a planned visit, which is exactly what keeps repairs small.
