Honda Accord 2003-2007: problems, engines, fuel economy, pros and cons, photos

Updated: July 09, 2021
The 2003-2007 Accord is a roomy, well-designed mid-size car with good handling. The Accord scored well in government crash tests. It comes as a front-wheel drive sedan or two-door coupe, with a 4-cylinder or V6 engine. The 4-cylinder engine is good on gas.

The interior is nicely finished. Front seats are comfortable and supportive. The rear seat space is generous. The trunk is large and the rear seatbacks fold down to accommodate longer items.

When it was newer, the Accord was one of the top recommended cars, however with age, problems are starting to show up. Some model years fared better than others. Still, it's not uncommon to find this generation Honda Accord lasting for well over 300,000 miles. What are some of the reported problems?

Reported problems: A starter motor can go at higher mileage. The symptom is the car won't start and the engine will not make a cranking sound when starting the car. Of course, a bad battery or another problem can also cause the same issue. To confirm a bad starter motor, mechanics usually test the battery first and then check the voltage at the starter control terminal, read more. Replacing a starter motor costs between $390 and $650. Watch these videos for more info.
At higher mileage, the air intake hose (duct) that connects the air filter to the throttle body can crack/break, causing a lack of power, stalling and the Check Engine light with the code P0171. It's a cheap part and is easy to replace. Read more about it here: Vacuum leaks. See these videos.

A bad oxygen sensor can cause the code P0141, which is quite common in this car. Replacing the sensor usually solves the problem. We found many videos on this problem.
Rear O2 sensor failures are common ($250-$430 to replace).

The audio & HVAC display not working is another common issue in early models. The solution is to replace an audio unit, although there are many YouTube videos describing the repair of the circuit board inside the audio system. This thread provides some pictures.

A bad A/C clutch or clutch relay can cause the A/C not to work. The relay is cheap and easy to replace. Watch these YouTube videos.

There are numerous complaints about automatic transmission failures, mostly in the 2003 and 2004 V6 models, although there are some transmission complaints in the 4-cylinder models too. Replacing the transmission with a used unit or rebuilding it can cost up to $3,000.

Excessive engine oil consumption is mentioned often too. If you notice that the engine oil level drops as you drive, check it regularly and top up as needed. Driving with low oil level will cause the engine to wear faster.

Engines: Two engines were offered: the 166-hp 2.4L 4-cylinder K24 and the smooth and powerful 244-hp 3.0L J30 V6.

Transmission choices included a 5-speed automatic or 5-speed manual. A 6-speed manual transmission was available in late EX V6 models. The K24 engine is well known and is used in many Honda cars. It is a fuel efficient low-maintenance workhorse, but you need to make sure it's not running low on oil. It's known to consume oil at higher mileage.

Fuel Economy: The 2007 4-cylinder automatic Accord is rated at 21/31 mpg city highway or 25 mpg combined. The 2007 4-cylinder automatic Accord can travel for up to 431 miles (693km) on one 17.1-gallon (64.7L) tank of gas. The 2007 V6 Accord with an automatic transmission is rated at 18/26/21 mpg city/highway/combined.

Handling and ride: On the road, the Accord handles well. The steering is responsive and precise and provides a good road feel. The ride is firm but comfortable. Some road and wind noises are noticeable at higher speeds.

The 4-cylinder engine is strong enough for daily driving, while the V6 is one of the most powerful in its class.

Timing belt or chain: The K24 4-cylinder engine has a timing chain, but the 3.0L V6 does have a timing belt that needs to be replaced at recommended intervals.

Pros: Fuel economy in 4-cylinder models, V6 power, good handling, responsive steering, safety ratings, roomy interior, easy to maintain.

Cons: Road and wind noise, paint chips easily, automatic transmission problems in early models.

What to look for when buying a used Honda Accord: Don't buy a car if the "Check Engine" light is on before you know what the problem is; once we have been contacted by a person who bought a Honda Accord over eBay with the "Check Engine" light on. After further diagnostic, It turned out that the engine needed to be rebuilt due to lack of compression in one of the cylinders. Check the automatic transmission fluid. If it smells burnt or looks very dirty, avoid the car.

During a test-drive, watch out for anything irregular with the automatic transmission; it is a weak spot. If there is a "clunk" or a long delay when shifting into Reverse, avoid the car. When inspecting a car, check the engine oil level; low oil level could indicate possible oil consumption.
