15 Honda Accord 2003 Problems
This list compiles the frequent failures and complaints reported by thousands of Accord owners over the years. We’ve ranked them based on how often they occur and how serious they can be.
1. Faulty Automatic Transmission
This is the most infamous and costly problem. The 4-cylinder models with automatic transmissions are particularly prone.
* The Complaint: Transmission slips, harsh shifting, jerking between gears, or complete failure. It often happens between 90,000 and 120,000 miles.
* The Cause: Worn clutch packs and poor design leading to premature wear of internal components.
* The Fix: A rebuild or replacement is usually necessary. Regular fluid changes with genuine Honda ATF can help prolong its life, but may not prevent it.
2. Power Window Regulator Failure
A very common and annoying issue. The windows stop moving up or down, or they make a loud grinding noise.
* The Complaint: The window won’t budge, or it falls down into the door.
* The Cause: The plastic clips or rollers in the regulator assembly break. The motor itself if often still good.
* The Fix: Replacing the window regulator. It’s a common DIY job that takes about an hour per door.
3. Ignition Switch Recall & Problems
Honda issued a major recall for the ignition switch. Even if yours was fixed, the switch can still cause headaches.
* The Complaint: The key sticks or is hard to turn, the car won’t start, or the steering wheel lock jams.
* The Fix: First, check if your VIN was included in the recall. If the problem persists, replacing the ignition switch and the key cylinder is the solution.
4. Failing Alternator
The alternator on these cars often gives out between 100,000 and 150,000 miles.
* The Complaint: The battery light comes on, electrical systems dim or act weird, and the car eventually dies.
* The Fix: Replacing the alternator. Test your battery and charging system regularly as the car ages.
5. Cracked Engine Block (V6 Models)
A serious and expensive engine problem specific to the 2003 V6 models. Honda extended the warranty for this.
* The Complaint: Coolant leaks externally from the engine block, leading to overheating. You’ll see coolant pooling under the engine.
* The Cause: A casting flaw that leads to cracks near the cylinder sleeves.
* The Fix: Engine block replacement. Check if your VIN qualifies under the extended warranty program, which covered it for 10 years/unlimited miles.
6. Leaking Power Steering Rack
The power steering rack is known to develop leaks from its seals.
* The Complaint: Low power steering fluid, a whining noise when turning, or fluid on your garage floor.
* The Fix: You can try a power steering stop-leak additive as a temporary fix, but a rack rebuild or replacement is often the permanent solution.
7. Failing Oxygen (O2) Sensors
With age and mileage, the oxygen sensors get lazy.
* The Complaint: The check engine light comes on with codes like P0420 (catalyst efficiency) or sensor-specific codes. You might notice slightly worse fuel economy.
* The Fix: Replacing the faulty sensor(s). The upstream sensors (before the catalytic converter) are more critical.
8. Worn Out Motor Mounts
The engine and transmission mounts, especially the front and rear, get soft and tear.
* The Complaint: Excessive vibration in the cabin, especially at idle or when shifting. You might hear clunks during acceleration or gear changes.
* The Fix: Replacing the broken mounts. It makes the car feel new again.
9. Faulty Starter Motor
A classic wear item that eventually fails.
* The Complaint: A single loud “click” when you turn the key, or the starter cranks very slowly.
* The Fix: Replacing the starter motor. Ensure your battery and connections are good first, as they can mimic starter symptoms.
10. Dashboard Cracking & Melting
The dashboard material is prone to cracking, becoming sticky, or even melting in hot climates.
* The Complaint: Glare on the windshield, a sticky surface, or an ugly, cracked dash.
* The Fix: Dashboard covers or a full dashboard replacement. There are also professional reconditioning services.
11. Headlight Lens Hazing
The plastic polycarbonate lenses oxidize and turn yellow and cloudy.
* The Complaint: Severely reduced nighttime visibility and an aged appearance.
* The Fix: You can try a headlight restoration kit for a temporary fix. For a long-term solution, replace the headlight assemblies.
12. Failing AC Compressor Clutch
The air conditioning compressor’s magnetic clutch wears out.
* The Complaint: The AC blows warm air, and you might hear a squealing or grinding noise from the compressor when the AC is on.
* The Fix: Sometimes just the clutch assembly can be replaced. Often, the whole compressor is swapped if it’s old.
13. Rear Brake Caliper Seizure
The rear calipers, especially in areas that use road salt, are prone to seizing.
* The Complaint: The car pulls to one side during braking, you smell burning brakes, or the rear brakes wear out extremely fast.
* The Fix: Freeing or replacing the seized caliper. Regular brake service and cleaning can help prevent this.
14. Fading & Peeling Clear Coat
The factory paint, especially on darker colors, is notorious for clear coat failure.
* The Complaint: The roof, hood, and trunk lid look chalky and the clear coat peels off in sheets.
* The Fix: Once it starts, the only real fix is a repaint. Regular washing and waxing can delay the onset.
15. Blend Door Actuator Failure
The little motor that controls where the air flows (feet, face, windshield) breaks.
* The Complaint: A loud, repetitive clicking noise from behind the dashboard, especially when you start the car or change the vent setting. The air may not come out of the correct vents.
* The Fix: Replacing the faulty actuator. It’s a common job, but requires some dashboard disassembly.
How to Check Your 2003 Accord for These Issues
Don’t wait for a breakdown. Here’s a quick step-by-step inspection you can do:
1. Start the car. Listen for any unusual noises—clicking from the dash, grinding from windows, or a slow crank.
2. Check the dashboard. Look for the check engine light, battery light, or any other warning lights. Note any glare from cracks.
3. Test all electronics. Roll every window up and down. Test all power locks and mirrors.
4. Inspect for leaks. Look under the car after it’s been parked for a while. Check for red (power steering) or green (coolant) fluid.
5. Examine the paint. Look at the roof and hood in direct sunlight for fading or peeling clear coat.
6. Test drive. Feel for transmission slipping or harsh shifts. Notice any vibrations at idle. Test the brakes for pulling.
Maintenance Tips to Avoid Common Problems
Prevention is cheaper than repair. Follow these tips:
* Transmission Care: Change the automatic transmission fluid every 30,000-60,000 miles with Honda ATF. Avoid harsh towing.
* Battery & Charging: Have your battery and alternator output tested annually, especially before winter.
* Cooling System: Flush and replace coolant every 5 years or 60,000 miles. Monitor the temperature gauge.
* Brake Service: Have your brakes inspected regularly. Ensure caliper slides are lubricated.
* Use Quality Parts: For critical items like sensors and ignition parts, OEM or high-quality aftermarket is best.
Is the 2003 Honda Accord Still a Good Buy?
Despite this list, the 2003 Accord can be a great used car. Its strengths—spacious interior, comfortable ride, good fuel economy—are still true. The key is knowing what your getting into.
If you’re looking at buying one:
* Get a pre-purchase inspection from a trusted mechanic. It’s worth every penny.
* Ask for service records. Look for proof of transmission fluid changes and timing belt replacement (on V6 models).
* Check the VIN for open recalls, especially for the ignition switch and airbags.
Budget for immediate repairs. Assume it will need something from the list above.
Frequently Asked Questions (FAQ)
