2020 Honda Accord Starter Issues: Diagnosis and Repair Guide

How to Fix Starter Issues on Your 2020 Honda Accord

Experiencing starter problems with your 2020 Honda Accord can be frustrating. You might hear grinding noises or the engine might fail to start altogether. One owner shared their experience: "However... it made it about 13 years and 216k miles before showing signs of failure! I feel like it had a good run." — Agitated-Contact7686 (source) This guide will help you diagnose and address these issues, based on insights from other 2020 Honda Accord owners.

Symptoms

A primary symptom is a distinct grinding noise when you attempt to start the engine. This noise usually indicates a problem with the starter motor engaging properly with the flywheel. You might notice this occurring intermittently at first, eventually becoming more frequent.

Another common symptom reported by owners is the complete failure of the engine to start. You may turn the key or push the start button, and nothing happens, or you might hear a clicking sound. This suggests a problem with the starter motor receiving power or failing internally.

Some owners have also reported intermittent starting issues. The car might start fine one day and then refuse to start the next. This can be due to a weakening starter motor, corroded connections, or a failing component within the starting system. Addressing these symptoms promptly can prevent further damage.

The location of the noise can also provide clues. Grinding noises localized near the engine typically indicate a problem with the starter's interaction with the flywheel. Electrical problems, such as a faulty solenoid, could also contribute to starting failures.

Most Likely Cause

Based on owner reports, the most likely cause of starter problems in your truck is the starter itself failing, possibly due to wear and tear. The starter motor is responsible for turning the engine over until it starts running on its own. Over time, the internal components of the starter can wear out, leading to reduced performance and eventual failure.

Another common issue is a worn or damaged flywheel. The starter engages with the flywheel to turn the engine. If the flywheel's teeth are damaged or worn, the starter may not be able to properly engage, resulting in a grinding noise or failure to start. Inspecting the flywheel for damage is crucial when diagnosing starter problems.

Furthermore, compromised electrical connections can hinder the starter's ability to function correctly. As one owner pointed out, "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." — Glum-North-1114 (source) Corrosion or loose connections can prevent the starter from receiving the necessary current to operate.

How to Diagnose

Begin by inspecting the battery connections. Ensure they are clean and tight, free from corrosion. Use a wire brush to clean any corrosion you find. A loose or corroded connection can prevent the starter from receiving enough power.

Next, check the battery's voltage using a multimeter. A fully charged battery should read around 12.6 volts. If the voltage is significantly lower, the battery might be weak or dead, which could prevent the starter from engaging. Consider having the battery load-tested at an auto parts store.

Listen for a clicking sound when you turn the key. If you hear a click but the engine doesn't turn over, the starter solenoid might be the issue. The solenoid is responsible for engaging the starter motor. You can try tapping the starter with a hammer while someone tries to start the engine. If it starts, the starter is likely failing and needs replacement.

Inspect the starter and flywheel for any visible damage. If possible, remove the starter and visually inspect the flywheel teeth for wear or damage. A damaged flywheel can cause a grinding noise when the starter engages.

Tools needed:

• Multimeter
• Wrench set
• Socket set
• Wire brush
• Hammer

Step-by-Step Fix

1. Disconnect the Negative Battery Cable: Before starting any electrical work, disconnect the negative battery cable to prevent electrical shocks.

2. Locate the Starter: The starter is typically located on the engine block near the transmission. Consult your truck's repair manual for the exact location.

3. Remove the Starter Wires: Disconnect the wires connected to the starter solenoid. Make sure to note the position of each wire for correct reinstallation.

4. Remove the Starter Mounting Bolts: Use a socket wrench to remove the bolts holding the starter in place. These bolts can be tight, so use a breaker bar if needed.

5. Remove the Starter: Carefully remove the starter from the engine compartment.

6. Inspect the Flywheel: Visually inspect the flywheel teeth for any damage or wear. If the flywheel is damaged, it may need to be replaced.

7. Install the New or Remanufactured Starter: Install the new or remanufactured starter in the reverse order of removal. Ensure all bolts are tightened to the correct torque specifications.

8. Reconnect the Starter Wires: Reconnect the wires to the starter solenoid, making sure each wire is in its correct position.

9. Reconnect the Negative Battery Cable: Reconnect the negative battery cable to the battery.

10. Test the Starter: Attempt to start the engine. If the engine starts without any grinding noises, the issue is resolved.

One owner, Agitated-Contact7686, shared their experience: "I am broke so I got a reman with a 1 year warranty for 215$. Do not have the time to spare to wait on a RockAuto shipment." (source) This highlights the option of using a remanufactured starter to save on costs.

Some owners have reported going with Denso starters. "They want $514 for an oem so I went with a Denso hopefully it works, it was around $330" ($514) — WVU-Miami-fan (source).

Parts and Tools Needed

• New or Remanufactured Starter: Denso is a popular brand, with prices varying based on retailer and availability.
• Socket Set: Essential for removing and installing bolts.
• Wrench Set: Needed for disconnecting wires and tightening bolts.
• Wire Brush: For cleaning battery terminals and connections.
• Multimeter: To test battery voltage and continuity.
• Gloves: To protect your hands.
• Safety Glasses: To protect your eyes.

Real Owner Costs

Based on owner reports, the cost to fix a starter problem varies.

• Remanufactured Starter (DIY): $215 (Agitated-Contact7686) (source)
• Denso Starter (DIY): $330 (WVU-Miami-fan) (source)
• OEM Starter (Shop Estimate): $514 (WVU-Miami-fan) (source)

These costs reflect parts only. Labor costs at a shop can significantly increase the total cost.

DIY vs. Shop:

• DIY: Saves on labor costs but requires mechanical knowledge and tools.
• Shop: Higher cost, but ensures the job is done correctly and often comes with a warranty.

Prevention

Regularly inspect and clean battery terminals and connections to prevent corrosion, ensuring good electrical contact. As Glum-North-1114 advised, "If you haven't already, be sure to check battery health, battery cables and connections for signs of corrosion. The starter motor draws more current than anything else in the car." (source)

Ensure that the battery is properly maintained and replaced when necessary. A weak battery puts extra strain on the starter, potentially shortening its lifespan. Get your battery tested regularly, especially in extreme temperatures.

Avoid repeatedly cranking the engine for extended periods. This can overheat the starter motor and cause premature failure. If the engine doesn't start after a few attempts, diagnose the underlying issue instead of continuing to crank the engine.

Consider using a fuel system cleaner periodically to keep the fuel injectors clean. While not directly related to the starter, a clean fuel system ensures the engine starts more easily, reducing the load on the starter.
