2020 Honda Accord Starter Problems? Here's How to Fix It

How to Fix Starter Replacement

Dealing with a failing starter in your 2020 Honda Accord can be frustrating, but it's a repair that many owners tackle themselves or entrust to a mechanic. Recognizing the symptoms early can save you from being stranded. As one owner shared: "However... it made it about 13 years and 216k miles before showing signs of failure! I feel like it had a good run." (source) This guide will walk you through the symptoms, diagnosis, repair, and prevention of starter issues in your vehicle.

Symptoms

A failing starter in your Accord will often present with several telltale signs. One of the most common symptoms is a clicking sound when you turn the key. This clicking indicates that the starter solenoid is engaging but not receiving enough power to turn the engine over. You might hear a single click or a series of clicks, but the engine won't start.

Another symptom reported by owners is a buzzing sound coming from the starter area. This buzzing can indicate a problem with the starter motor itself or with the electrical connections leading to it. Sometimes, the buzzing may only occur when the engine is cold, indicating an internal fault that worsens with temperature changes.

In some cases, a cold start rattle might be an indicator. If the starter motor is not engaging properly or is worn, it might produce a rattling sound upon starting. This rattle can be more noticeable during cold starts when the engine components are still settling. Pay attention to any unusual sounds coming from the engine bay during ignition.

Finally, a complete failure to start, especially in cold weather ("ice"), can be a symptom of a failing starter. The starter might be struggling due to increased resistance caused by cold temperatures or internal wear. If your car frequently fails to start in cold conditions, the starter is a prime suspect.

Most Likely Cause

Based on owner reports, one of the most likely causes of starter issues in your 2020 Honda Accord is a failing starter itself. The starter motor is responsible for cranking the engine and initiating the combustion process. Over time, the internal components of the starter, such as the solenoid, brushes, and motor windings, can wear out, leading to decreased performance or complete failure.

Compromised cables and connections leading to the starter can also be a significant contributing factor. "The starter motor draws more current than anything else in the car. Compromised cables and/or connections can keep the starter motor from being able to draw the current it needs," notes one owner (source). Corrosion or loose connections can prevent the starter from receiving the necessary power to operate correctly.

How to Diagnose

Diagnosing a starter problem requires a systematic approach. Here's a step-by-step process:

1. Check the Battery: Ensure the battery is fully charged and in good condition. Use a multimeter to check the battery voltage. It should read around 12.6 volts when the engine is off. If the voltage is significantly lower, the battery may be the issue, or it may be contributing to premature starter failure by overworking it.
2. Inspect Battery Cables and Connections: Examine the battery terminals and cable connections for corrosion or looseness. Clean the terminals with a wire brush and tighten any loose connections. Pay close attention to the ground connections, ensuring they are secure and free from rust.
3. Listen for Clicking or Buzzing: When you turn the key, listen carefully for any clicking or buzzing sounds coming from the starter area. A single click usually indicates a faulty solenoid, while a buzzing sound might suggest a weak starter motor.
4. Check the Starter Relay: Locate the starter relay in the fuse box (consult your owner's manual for the exact location). Swap the starter relay with an identical relay from another system (e.g., horn relay). If the car starts with the swapped relay, the original relay is faulty and needs replacement.
5. Bypass the Starter Relay (Caution): This step requires caution and should only be performed if you have experience with electrical systems. Use a jumper wire to bypass the starter relay. If the starter engages and the engine cranks, the problem lies in the relay or the wiring leading to it.
6. Test the Starter Directly: Disconnect the start wire from the starter solenoid. Using a jumper cable connected to the positive terminal of the battery, touch the start terminal on the starter solenoid. If the starter engages, the problem is in the wiring or ignition switch. If it doesn't engage, the starter is likely faulty.
7. Inspect the Flexplate: Although less common, inspect the flexplate (or flywheel in manual transmissions) for damaged teeth. A damaged flexplate can prevent the starter from engaging properly.
8. Check the Clutch Interlock Switch (Manual Transmissions): Ensure the clutch interlock switch is functioning correctly. This switch prevents the car from starting unless the clutch pedal is depressed. A faulty switch can prevent the starter from engaging, even if the starter itself is in good condition.

Tools needed:

• Multimeter
• Socket set
• Wrench set
• Jumper wire
• Wire brush
• Protective gloves
