Why did Lexus discontinue the IS300?

Lexus has not globally discontinued the IS300; the badge remains in some markets, while other regions have streamlined the lineup as the company pivots toward SUVs and electrified powertrains.

What the IS300 is and how it has evolved

The IS line has long served as Lexus’ compact sport sedan, with the IS300 name historically tied to different powertrains across generations. In earlier eras, IS300 denoted a 3.0-liter V6 variant; in later years, markets around the world used different trims—such as IS 250 and IS 350 in the mid-generation lineup—and, more recently, turbocharged and hybrid configurations appeared under the IS300 umbrella in various regions. The current global lineup typically includes variants like the IS 300 (2.0L turbo) alongside the IS 350 and, in some markets, high-performance or hybrid options. The exact powertrain and badge configuration can vary by country and model year, reflecting regional preferences and regulatory requirements.

Why the IS300 badge has changed across markets

There are several broad factors that drive changes to model badges and trims like the IS300. The following considerations are commonly cited by automakers facing market shifts and regulatory pressures.

• Market demand and sedan decline: Consumers increasingly favor SUVs and crossovers, reducing demand for lower-volume sedan variants such as the IS300 in many regions.


• Product lineup simplification: Automakers frequently streamline offerings to focus on best-sellers and profitable configurations, which can lead to retiring older trims or consolidating powertrain options.


• Electrification strategy and powertrain realignments: As brands push toward electrified powertrains, some internal-combustion-only variants are retired or renamed to align with branding and efficiency targets.


• Regional regulatory and market differences: Emissions standards, tax incentives, and local competition influence which trims remain available by market and model year.

Concluding paragraph: Taken together, the fate of the IS300 badge is not uniform. In some markets the turbocharged IS300 remains available or has been updated with new powertrains, while in others the brand has retired older trims or realigned the lineup to emphasize electrified models and sport-utility options.

Regional status and buyer guidance

In markets where the IS line persists, buyers may still encounter the IS300 as part of a broader performance-oriented lineup. In regions that have pared back sedans, shoppers might see only IS 350, IS 500, or hybrid variants, or may find the IS 300 badge replaced by other nameplates. For prospective buyers or used-car shoppers, it’s important to confirm the exact trim and powertrain for the model year and market in question, since availability can vary by country and dealer.

Summary

The IS300 has not been universally discontinued by Lexus. Instead, the badge’s presence and the availability of related variants have varied by market as Lexus adapts to shifting consumer preferences, stricter regulations, and a corporate push toward electrification and SUVs. In some regions the IS300 remains a current option or has been refreshed with updated powertrains, while in others the brand has streamlined or replaced sedans with newer offerings. The overall trend reflects a broader industry move away from traditional sedans toward more versatile, electrified crossovers.

What is the common problem of Lexus 300?

Problem: The IAC (Idle Air Control) valve and the EGR (Exhaust Gas Recirculation) valve are prone to becoming blocked with carbon build-up. If you are experiencing trouble starting your vehicle or irregular engine idling, these parts may need cleaning.

What are common problems with Lexus IS 300?

Common Lexus IS300 problems include a sticky/melting dashboard in older models (2002−20052002 minus 20052002−2005), EVAP system and Mass Air Flow (MAF) sensor issues causing check engine lights, and transmission hesitation with automatic transmissions. Other issues reported across different model years are poor fuel economy, unreliable technology in newer models, and worn-out components like headlights and brakes.

Older models (2001-2005)

• Sticky/Melting Dashboard: The soft-touch, rubbery coating on the center console and dashboard of 2002-2005 models can become sticky and degrade due to heat, causing permanent fingerprints and scratches. The 2001 model does not have this issue. 
• Transmission Hesitation: Automatic transmission models may exhibit a few seconds of delay between pressing the throttle and the car engaging and moving forward, particularly at low speeds. 
• EVAP System Failure: The evaporative emissions (EVAP) system is prone to failure, often triggering a "Check Engine" light. 
• Mass Air Flow (MAF) Sensor: A faulty MAF sensor can cause a lack of power and trigger a "Check Engine" light. 
• Cloudy Headlights: Due to age and sun exposure, headlights can become cloudy and foggy. 
• Other Issues: Owners have also reported problems with CD changers, aging leather seats, and sometimes the navigation system. 

Newer models (2015 and later) 

• Technology Issues: Some reviewers note that the technology can be unreliable. Newer models may also lack features like Apple CarPlay. 
• Navigation and Lexus Enform: The infotainment system and its features have been criticized for being unreliable by some users. 
• Poor Fuel Economy: Fuel efficiency can be disappointing for some drivers. 

Other model years and general issues

• Brake Wear: Like most vehicles, IS300s will require regular replacement of brakes and rotors.
• Rust: Depending on the climate, rust can be an issue, especially in areas where salt is used for snow and ice removal.
• Battery Drain: Some owners report a battery drain after a few days of inactivity, though this can sometimes be within normal limits for certain models. 

Why did Lexus stop making the is?

Lexus is discontinuing the IS sedan primarily because its current generation is over a decade old and will be replaced by newer models, with the IS-500 and IS-300 production ending in late 2025. Other contributing factors include the need to shift to electrified platforms, evolving safety and emissions regulations in some markets, and an outdated interior infotainment system. While a new generation is expected to be released, the future lineup will likely have more electrified options and will not include a V8 engine.

Reasons for discontinuation

• Aging platform: The current IS generation has been around since 2013, making it the brand's oldest model. It is due for a complete redesign. 
• Shift to electrification: Lexus is moving toward more electrified vehicles, and the IS will likely be replaced by a model with more hybrid and electric options. 
• Outdated technology: The interior features an outdated Remote Touch interface, and the overall design is no longer competitive with modern rivals. 
• Safety and emissions standards: Some markets, like Australia, have discontinued the IS due to new safety regulations. Other markets may follow as regulations evolve. 
• Production changes: The discontinuation of the IS 500 and other models may free up production capacity for new vehicles at Lexus's Tahara plant.
