Car won't start in San Jose: do you need a jump-start or a tow?

Listen to what happens

Rapid clicking or a sluggish attempt to start: a weak battery or poor electrical connection is a possibility. It isn't proof that you need a new battery.

One click and no engine movement: the starter or its electrical circuit may be involved. A severely discharged battery can also produce a click.

The engine turns over normally but doesn't start: don't assume a battery boost will solve it. Tell the operator that the engine is turning; that's different from a car that does nothing when you press the start button.

Firestone's technicians explain why clicking can have several causes. These sounds are clues for the person helping you, not a reliable diagnosis on their own.

When a jump-start is a reasonable first step

Suppose the car drove normally, you parked it, and now it struggles to turn over. Perhaps an interior light stayed on. If the vehicle is in a safe place and the battery can be boosted safely, asking for jump-start assistance is reasonable.

But tell the operator about anything that happened before the car stopped. A car that lost power while driving deserves a different conversation from one that wouldn't start after sitting overnight.

A boost also doesn't tell you why the battery went flat. If the problem keeps returning, have the battery and charging system checked. Repeatedly getting the engine running leaves that question unanswered. AAA's battery warning signs.

When to stop trying

Don't attempt a jump-start if the battery is swollen, cracked, or leaking. Don't lean over it to investigate an unusual smell. Let the roadside operator know what you've noticed. Follow the vehicle's own instructions and get assistance if you can't identify the correct procedure. AAA's jump-start precautions.

If you see smoke or fire, move away from the vehicle and traffic and call 911. Vehicle-fire guidance.

A tow may be the practical next step if a correctly performed jump-start doesn't get the car running. If it starts and then stalls, have it assessed before trying to drive away. A charging-system problem is one possibility, but that behavior alone doesn't identify the failed part. AAA's battery and alternator guide.

Driving an EV? Explain which problem you have

An EV with a depleted traction battery has a different problem from one whose low-voltage system won't wake up. A conventional jump-start doesn't refill the battery that drives the car.

Give the make, model, year, remaining range if visible, and any dashboard message. The procedure and permitted connection points depend on the vehicle. Tesla's Model 3 guidance for running out of range describes the distinction and the need to arrange appropriate help. Don't apply one vehicle's procedure to every EV.

What to tell us when you call

Your exact parking location matters as much as the symptoms. “At the shopping center” can leave a driver looking through several separate lots.

Tell us the entrance you used, a nearby business or cross street, and whether the car is in an underground garage. Include any height limit you already know; you don't need to walk into traffic to check one.

It also helps to mention:

• Your car's year, make, model, and fuel type.
• What you hear or see when you try to start it.
• Whether anyone has already attempted a jump-start.
• Whether the car is boxed in, has a locked wheel, or cannot move.
• Your preferred repair shop if a tow becomes necessary.

Ask about the charge for the requested service and what would happen if a jump-start doesn't work. That avoids making a decision about a tow before you understand the options.
