Is the Lexus IS250 reliable?

Yes—overall, the Lexus IS250 is considered a reliable choice within the luxury compact segment, especially when it has been well-maintained. Reliability varies by model year and care history, but the brand’s reputation for durability generally holds up for well-cared-for examples.

The IS250 (sold largely from 2006 through 2013 in most markets) sits at the intersection of luxury and practicality. For prospective buyers or owners of a used vehicle, reliability hinges on maintenance records, mileage, and any recalls or service campaigns that may apply. A diligent check of service history and a thorough pre-purchase inspection are essential to gauge ongoing reliability.

Reliability at a glance

What owners report

Owners commonly note solid long‑term reliability for the IS250, with many reporting trouble-free operation for many miles when the car has received regular maintenance and timely part replacements. The model is praised for its refined engine sound, measured ride, and strong dealer network that supports routine service.

• Durable engine and drivetrain with a straightforward design that keeps routine maintenance predictable.


• Strong resale value and a reputation for longevity among luxury brands.


• Relatively simple electronics compared with some newer luxury models, which can help reduce surprise repair costs as the car ages.


• Availability of parts and service widely through Lexus dealers and independent shops.

Overall, the IS250 tends to perform reliably when it receives proper maintenance, but like any aging vehicle, it will require attention to wear items and aging systems as miles accumulate.

Common concerns and maintenance costs

As with many older luxury cars, some reliability concerns center on aging components rather than fundamental design flaws. Potential items to monitor include wear items in the suspension and chassis, electrical/infotainment quirks in older models, and cooling-system components. Additionally, maintaining the transmission and ensuring a clean service history can influence long‑term reliability.

• Age-related wear on suspension components (control arms, bushings, shocks/struts) that can affect ride quality and handling.


• Electrical or infotainment glitches in higher-mileage examples, sometimes related to sensors or communication modules.


• Cooling-system wear (radiator hoses, water pump, thermostat) that can lead to leaks or overheating if not addressed.


• Brake and tire wear that comes with age and miles; regular maintenance is essential for reliable operation.


• Transmission behavior in some earlier examples, including rough or hesitant shifts if hydraulic components or fluid changes are neglected; proper servicing mitigates many concerns.

For any used IS250, a careful inspection and a documented maintenance history are crucial to ensuring reliability over the coming years.

Reliability by model year and maintenance considerations

The IS250 was produced in the mid‑2000s to early‑2010s era, and reliability tends to reflect general aging of components in cars that are more than a decade old. Later MY years in the run (where available in some markets) benefited from incremental refinements and updated parts, but the core takeaway remains: consistent, timely maintenance is the most reliable predictor of continued reliability. When purchasing used, prioritize service records, verify any recalls or CAMs (campaigns) tied to the VIN, and have a trusted mechanic perform a pre-purchase inspection that includes engine, transmission, cooling, suspension, brakes, and electrical systems.

Checklist before buying a used IS250

• Review full maintenance history, focusing on timing/drive-train servicing, oil changes, and any suspension or brake work.


• Check recall status for your VIN and ensure campaigns have been completed.


• Test drive to assess transmission behavior (smooth shifts, no slipping or shuddering) and to identify any unusual noises.


• Inspect for oil or coolant leaks around the engine, seals, and the cooling system.


• Inspect suspension components for play, worn bushings, and leaks in shocks/struts.


• Assess the condition of tires, brakes, and rotors; uneven wear can indicate alignment or suspension issues.


• Evaluate electrical features (lights, climate control, infotainment) for glitches or failures.


• Have the vehicle scanned for trouble codes to catch latent issues not evident on a test drive.

With a comprehensive check and a solid service history, IS250s can remain reliable transportation well into higher mileage ranges.

Summary

The Lexus IS250 is typically regarded as a reliable choice within its class, especially when maintained regularly and bought with complete service records. Reliability is strongly influenced by model year and upkeep; aging components require attentive care, but the model benefits from Lexus’s historical durability, wide parts availability, and an established service network. For buyers, a thorough pre-purchase inspection and a VIN-specific recall check are essential to ensure long-term reliability.

What is the common problem with Lexus IS250?

Common problems with the Lexus IS250 include carbon buildup in the direct injection engine, which can lead to misfires and rough idling, and issues with the plastic dashboard material fading or becoming sticky. Other reported problems include various check engine light codes, a clicking noise from the rear suspension, and potential moisture damage to the amplifier or other electrical components due to clogged AC drain tubes.

Engine and drivetrain 

• Carbon buildup: This is a frequent issue, especially on second-generation models, due to the direct injection system and frequent idling. It can cause misfires, check engine lights, and rough idling. 
• Check engine light: Specific codes like P0751, P2714, P0894, or misfire codes (P0300-P0306) are reported, often related to the carbon buildup issue or other engine problems. 
• Transmission problems: Some drivers report transmission issues like slipping, which can be caused by a lack of fluid maintenance. 

Interior and electrical

• Sticky/aging dashboard: The plastic material on the dashboard can become sticky or fade over time, sometimes unresolved by recalls. 
• Moisture damage: Clogged AC drain tubes can lead to water leaking onto the carpet, and moisture can also get into the amplifier, causing it to malfunction. 
• Old infotainment system: The original infotainment system is often outdated, with common complaints about glitches, such as the radio randomly shutting off. 
• GPS and radio issues: Some owners have reported issues with the navigation system, sometimes fixable by a software or map disc update. 

Other issues

• Rear suspension noise: A clicking noise from the rear suspension has been reported by multiple owners. 
• Safety issues: Some specific model years have had safety recalls and investigations, including for airbag and steering components.
