Car sometimes starts, sometimes does not

Needs attention soon

intermittent no-start · starts fine most days but not always

Symptom description

The car starts normally most of the time, but occasionally and unpredictably fails to start, with no clear pattern.

Common causes

  • A failing ignition switch with worn internal contacts
  • A loose or corroded battery/starter connection
  • A failing starter motor or solenoid nearing the end of its life
  • A security/immobilizer system intermittently failing to recognize the key

What to check

Keep a simple log of when it fails to start (cold/hot, time of day, after rain) - intermittent faults are much easier to diagnose with this pattern.

Can you keep driving?

Plan ahead - an intermittent no-start can leave you stranded at an inconvenient time, so do not delay getting it diagnosed.
