What Problems Does the 2003 Lexus IS 300 Have?
The 2003 Lexus IS 300, like many vehicles of its era, has some commonly reported issues. One of the more prevalent concerns relates to the automatic transmission, which can sometimes develop issues with shifting or may eventually fail, especially on higher-mileage examples. While not as common as in some other brands, this is something potential buyers should have inspected.
Interior wear is also a frequent observation. The leather seats can show signs of cracking or tearing over time, and the plastic buttons on the dashboard and steering wheel might exhibit fading or stickiness. The power window regulators are another component that can fail, leading to windows getting stuck.
Electrical issues, though not widespread, do appear in owner forums. This can include problems with the ABS warning light coming on due to faulty wheel speed sensors, or issues with the power door locks and keyless entry system. The infotainment system, particularly the optional navigation, can also be slow or prone to freezing.
In terms of recalls, the 2003 IS 300 had a few. One notable recall addressed a potential issue with the driver's side airbag inflator. Another recall pertained to the fuel pump, which could potentially fail. It's always advisable to check with a Lexus dealer or the NHTSA website for any outstanding recalls on a specific vehicle.
Regarding long-term reliability, the IS 300 generally has a strong reputation, benefiting from Lexus's engineering and build quality. The robust 2JZ-GE engine is known for its durability and potential for modification if that's of interest. However, the longevity of components like the transmission, suspension bushings, and cooling system can be significantly influenced by how well the vehicle has been maintained. Regular fluid changes and proactive maintenance are key to maximizing its lifespan.

How long will the 2003 Lexus IS 300 last?
Based on owner data and typical maintenance habits, a well-maintained 2003 Lexus IS 300 can reasonably expect to serve its owner for 200,000 to 250,000 miles, and often beyond. Many owners report reaching or exceeding 300,000 miles with diligent care. The long-term durability is a significant strong suit, largely due to the robust 2JZ-GE engine. However, weaknesses can emerge over time. Automatic transmissions, as mentioned, are a point of concern for extended longevity without proper servicing. Suspension components like bushings and ball joints will eventually wear out, requiring replacement. The cooling system, including the radiator and water pump, should also be monitored and replaced proactively to prevent overheating issues that can compromise the engine. Regular oil changes and addressing minor issues promptly are crucial for achieving maximum lifespan.
What Technology & Safety Features are Included?
The 2003 Lexus IS 300 offered a respectable suite of technology and safety features for its time, aiming to provide a premium experience.
Entertainment: Standard entertainment typically included an AM/FM stereo with a CD player. A significant upgrade was the optional Bose premium audio system, which offered enhanced sound quality with more speakers. Some models were also equipped with an optional in-dash navigation system, though this system was considered basic by today's standards and may be slow to operate.
Comfort and Convenience Tech: Features like automatic climate control, power-adjustable front seats with driver's seat memory, power windows, power locks, and power mirrors were standard or commonly found. Keyless entry and ignition also added to the convenience.
Driver-Assistance Features: Standard driver-assistance technologies included Anti-lock Braking System (ABS) to prevent wheel lock-up during hard braking, Electronic Brake-force Distribution (EBD) to optimize braking performance, and Traction Control System (TCS) to help prevent wheel spin during acceleration. Some models might have offered stability control, though it was less common than on newer vehicles.
Safety Features: Beyond the driver-assistance systems, the 2003 IS 300 came with front airbags as standard. Optional front side-impact airbags were available to provide additional protection for the occupants' torsos in a side collision. The vehicle's structure was designed to absorb impact energy.
Crash-Test Ratings: The 2003 Lexus IS 300 received generally good crash-test ratings for its era. The National Highway Traffic Safety Administration (NHTSA) awarded it five stars for frontal driver and passenger protection, and four stars for side-impact protection for the front and rear seats (without side airbags). With side airbags, side-impact ratings would be higher. The Insurance Institute for Highway Safety (IIHS) rated it as "Good" in its frontal offset crash test. It's important to note that these ratings are from a different era and should be considered in that context.

2003 Lexus IS 300 Prices and Market Value
When new, the 2003 Lexus IS 300 had an MSRP that typically ranged from around $30,000 to $35,000, depending on the body style (sedan or Sportcross) and selected options.
Today, the used market prices for a 2003 Lexus IS 300 can vary significantly, generally falling between $3,000 and $8,000. Excellent condition, low mileage examples, especially those with desirable manual transmissions or the Sportcross body style, can command prices at the higher end of this spectrum.
The IS 300 has experienced a moderate level of depreciation. Its resale value is positively influenced by Lexus's reputation for reliability, its timeless styling, and the enthusiast following it has garnered. Conversely, factors that detract from resale value include high mileage, evidence of poor maintenance, the presence of common mechanical issues (like transmission problems), and interior wear. Manual transmission models tend to hold their value slightly better than automatics due to their enthusiast appeal.

How Does the 2003 Lexus IS 300 Compare to Other Sedan?
The 2003 Lexus IS 300 competed in the compact luxury sedan segment against rivals like the BMW 3 Series (E46), Audi A4 (B6), and the Infiniti G35 (V35).
Performance: The IS 300's 215-horsepower inline-six offered a smooth and capable power delivery. The BMW 3 Series, particularly the 330i with its 225-hp inline-six, often provided a more engaging driving dynamic and sharper handling. The Infiniti G35, with its potent 280-hp V6, clearly outpaced the IS 300 in straight-line acceleration and offered a sportier feel. The Audi A4, while refined, typically had less potent engine options in this year and was more comfort-oriented.
Features: Lexus traditionally excels in interior refinement and standard luxury features. The IS 300 boasted a well-appointed cabin, premium materials, and a strong feature set, including optional navigation and a premium audio system. BMW and Audi also offered high-quality interiors with advanced options, though sometimes at a steeper price. The G35 offered a good mix of sportiness and luxury features.
Reliability: This is where the IS 300 truly shines. Lexus has a well-earned reputation for bulletproof reliability, often surpassing its German and Japanese competitors in long-term dependability surveys. While the E46 3 Series can be reliable with proper maintenance, it often requires more frequent and costly repairs. The G35 is generally reliable but can sometimes exhibit more minor electrical gremlins than a Lexus. The A4's reliability can be more variable.
Price: When new, all these vehicles were similarly priced luxury options. On the used market, the 2003 IS 300 often represents a more budget-friendly entry into the luxury sedan segment compared to comparable BMWs or Audis, especially when considering potential maintenance costs.
Alternatives:
* Similar: For a similar blend of sportiness and luxury, the Infiniti G35 is a strong contender, offering more performance but potentially slightly less bulletproof reliability.
* More Engaging Drive: If driving dynamics are paramount, the BMW 3 Series (E46), particularly a 325i or 330i, is a benchmark, though expect higher maintenance bills.
* Comfort-Oriented: For a more comfort-focused yet still luxurious experience, an Acura TL of the same era could be considered, often offering good value and reliability.
