2020 Pacifica Won't Start - Just Clicks, Battery is Good

Vehicle: 2020 Chrysler Pacifica Limited

My 2020 Chrysler Pacifica Limited, with about 45,000 miles, suddenly won't start. When I press the start button, all I hear is a single click, and then nothing. The dashboard lights up, the radio works, and the headlights are bright, so I don't think it's the battery. I even had the battery tested at an auto parts store, and they said it's good.

Could this be a starter issue, or something more complex like an immobilizer problem? I've tried both key fobs, and neither makes a difference. There are no specific warning lights on other than the usual ones that come on before starting.

Has anyone run into this with their Pacifica? It's really frustrating, especially with kids. Any ideas on what I should check next?

Your 2020 Chrysler Pacifica's 'single click, no start' symptom, despite a confirmed good battery, points towards a few common issues. This typically indicates that power is reaching the starter solenoid, but the starter motor itself isn't engaging or turning the engine over. Here's what to investigate:

  1. Starter Motor/Solenoid: The most likely culprit. The single click you hear is often the starter solenoid engaging, but if the starter motor itself is faulty (worn brushes, bad windings), it won't spin. The solenoid could also be failing internally, preventing the main contacts from closing. A common temporary fix for a failing starter is to gently tap it with a hammer while someone tries to start the car (if it's accessible and safe).
  2. Starter Relay: In the fuse box (usually under the hood), there's a starter relay. This relay sends power to the starter solenoid. You can try swapping it with an identical, non-critical relay (like the horn relay) to see if the problem resolves. If it does, replace the relay.
  3. Corroded Battery Cables/Connections: Even if the battery tests good, corroded or loose battery terminals, or a poor connection at the starter itself, can prevent sufficient current from reaching the starter motor. Check both positive and negative terminals, as well as the ground strap from the engine to the chassis.
  4. Neutral Safety Switch (PNP Switch): While less common for a 'single click' symptom, if the Powertrain Control Module (PCM) doesn't correctly register that the vehicle is in Park or Neutral, it won't allow the starter to engage. Try shifting into Neutral and then attempting to start.

When to See a Shop: If you've checked the battery connections, tried swapping the starter relay, and confirmed the battery is fully charged, and the vehicle still won't start, it's time to visit a professional mechanic. Diagnosing a faulty starter or more complex electrical issues requires specialized tools and expertise to ensure proper repair and avoid further damage. They can perform voltage drop tests and directly test the starter motor.
