What Lexus is models to stay away from?

In short, there isn’t a single Lexus model you must avoid across the board. Lexus vehicles are known for reliability, but when shopping used, it’s wise to steer clear of very old examples or those with incomplete maintenance histories. Focus on age, mileage, and documented service records to minimize risk.

In this article, we examine reliability patterns in the Lexus lineup, highlight common warning signs for used purchases, and offer practical steps to evaluate potential buys. The goal is to help readers separate solid used-Lexus bets from cars that may require costly repairs down the road.

Reliability landscape: what tends to cause concern

Across the Lexus lineup, the biggest risk factors tend to be age, mileage, and the complexity of newer technology. As models age, wear on engines, transmissions, hybrid systems, and suspension components can lead to expensive repairs. Hybrid variants carry the added consideration of battery health and inverter reliability. Here are the general trends buyers should watch for:

• Age and mileage: Older vehicles with higher mileage are more likely to experience wear in drivetrain and electrical systems.


• Hybrid powertrains: Batteries and hybrid electronics can become costly to repair or replace as the car ages.


• Suspension and steering components: Air- or coil-spring suspensions and steering systems may require attention beyond routine maintenance.


• Electronics and infotainment: More modern Lexus models pack advanced electronics that can have software and sensor-related faults.

As you review a used Lexus, keep these factors in mind and prioritize models with well-documented maintenance records and recent major service milestones.

Practical shopping checklist for used Lexus buyers

Before you walk into a dealership or a private sale, use this checklist to screen vehicles and reduce the chance of buying a trouble-prone example.

• Check the vehicle history: request full service records, accident history, and recall status. Verify that any open recalls have been addressed.


• Inspect the powertrain: have a mechanic review the engine for oil leaks, unusual noises, and compression. For hybrids, confirm battery and inverter health with a qualified technician.


• Test the transmission: ensure smooth gear changes and no slipping or shuddering in automatic transmissions.


• Evaluate the suspension: listen for mounting noises, inspect for uneven tire wear, and assess ride quality across rough pavement.


• Inspect electronics: test all infotainment features, camera systems, and driver-assistance tech for proper function.


• Consider a pre-purchase inspection: a certified technician can identify issues not visible in a test drive or history report.

A thorough inspection and clean maintenance history often distinguish a reliable used Lexus from a potential money pit.

Model-year clusters to scrutinize (and why)

There isn’t a universal "bad" model across Lexus, but certain model-year clusters have shown more owner-reported problems in reliability surveys or service histories. When evaluating used examples, proceed with heightened scrutiny for these clusters and prioritize those with complete service records and proof that major maintenance items were completed. If you want to minimize risk, lean toward later-generation models and recent used examples with reputable maintenance histories.

• Older mid-2000s models: These vehicles may show wear typical of aging luxury cars, including engine, transmission, and suspension components that typically require more frequent maintenance.


• Early hybrid models: Battery longevity and inverter reliability can influence ownership costs, so verify hybrid-system service history and contemplate a stress test of the battery/ECU.


• High-tech, late-model features: Cars with advanced driver-assistance packages can incur software and sensor-related faults as they age.

Always couple this with a professional pre-purchase inspection and a review of the vehicle’s maintenance journal to verify any major work was properly addressed.

Bottom line: stay informed, stay prepared

In sum, there isn't a single Lexus model you must avoid across all markets. The key to a smart used-Lexus purchase is careful selection based on age, mileage, and documented service history, along with a thorough pre-purchase check focusing on powertrain, hybrid systems, suspension, and electronics.

Summary: Lexus remains a leader in reliability, but used purchases require diligence. Focus on well-documented maintenance, avoid very old examples unless they have a flawless service history, and get a professional inspection to minimize the risk of expensive surprises.

Notes: For the most accurate guidance, consult reliability rankings from consumer reports, J.D. Power, and regional forums, and tailor recommendations to your budget and ownership expectations.

Which Lexus IS model is most reliable?

The most reliable Lexus IS models are generally the IS 350 from the third generation (2014-2021) and newer, which avoids the reliability issues found in the earlier IS 250's V6 engine. The IS 350 F Sport is a particularly strong choice due to its reliable, naturally aspirated V6 engine and smooth transmission. For the seventh generation IS, the 2022, 2023, and 2024 models are considered reliable choices, especially the gas-powered versions. 
Most reliable Lexus IS models 

• IS 350 (Third Generation: 2014-2021): The most reliable choice is the non-AWD IS 350 model from this generation, which features the updated and more efficient 8-speed automatic transmission. 
• IS 350 F Sport: The 350 F Sport is considered a reliable sports sedan due to its naturally aspirated V6 engine and smooth, durable transmission, even at high mileage. 
• Seventh Generation (2022, 2023, 2024): Recent models from this generation have strong reliability scores, with the 2024 model having a particularly high rating from JD Power. 
• Older IS Models: While many Lexus models are reliable, earlier IS models, particularly the IS 250, had more reported reliability issues compared to the IS 350. 

Why these models are reliable

• Engine: The naturally aspirated V6 engine in the IS 350 is known for its durability. 
• Transmission: The 8-speed automatic transmission in the third-generation IS 350 is also highly reliable. 
• Overall quality: Lexus IS models benefit from Toyota's reputation for building reliable vehicles, and recent models maintain that strong reputation. 

What are the best years for the Lexus IS?

The best Lexus IS years are often cited as the 2006-2013 second generation for its blend of performance and reliability, particularly the 2012-2013 models which were the final years of that generation. The 2014-2016 third-generation models are also a strong option, representing the beginning of that redesigned platform with a more modern feel. For enthusiasts seeking the most modern performance, the later models in the third generation, particularly the IS 350, offer a compelling package.
