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.

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.
Overall: The 2003 and 2004 Accord have the most reported problems, and failing transmissions in the V6 Accord are reported by many sources. For example, as of October 2019, there are 914 complaints for the 2003 Accord and only 103 complaints for the 2005 Accord under the 'Powertrain' section at the NHTSA website. This means that the 4-cylinder 2005-2007 Accord is a better option. On the other hand, as of October 2019, the 2004-2007 Accord is listed as "recommended" at the Consumer Reports website.

A ripped intake boot (snorkel) can cause lack of power, Check Engine light and the code P0171. It's a cheap part and is easy to replace. Read more about it here: Vacuum leaks.
A starter motor can go at higher mileage. The cost to replace a starter is between $300 and $550.
Rear O2 sensor failures are common ($250-$430 to replace).
Excessive oil consumption is mentioned often too.
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.
A bad A/C clutch or clutch relay can cause the A/C not to work. See these Youtube videos.
