Do Lexus IS 250 have problems?

The Lexus IS 250 is generally considered a reliable luxury sport sedan, but as an older model it can develop wear-related problems common to used cars. Typical trouble spots include transmission behavior, engine oil leaks, electrical sensor faults, and suspension wear.


Produced roughly from 2005 to 2013 with a 2.5-liter V6, the IS 250 benefits from Lexus engineering and a reputation for long-term durability. However, mileage, maintenance history, and driving style heavily influence how often issues arise. When evaluating a used IS 250, it helps to know which components tend to age hardest, how they present, and what preventive steps can reduce future faults. Regular service history and a thorough pre-purchase inspection are especially important for this model.


Common Problems Reported by IS 250 Owners


Below are the broad problem areas most frequently cited by owners and service professionals. Each section notes typical symptoms and general approaches to address them.


Transmission and Driveline


Transmission behavior is among the most commonly discussed trouble spots for older IS 250s. Some owners report rough shifting or hesitation, which can stem from aging fluid, wear in the torque converter, or software calibration. In many cases, a transmission service or a dealer software update alleviates symptoms; more serious cases may require further inspection or replacement of worn components.



  • Rough shifting or hesitation on light to moderate throttle.

  • Occasional shudder during low-speed engagement, often improved by a fluid service or software update.

  • A need for proactive maintenance rather than waiting for a fault code to appear.


Regular transmission fluid changes and keeping the control software current are common preventive steps, and addressing early signs can prevent more costly repairs later.


Engine, Oil, and Emissions


Oil leaks and emissions-related sensor faults appear with age on some IS 250s. Valve cover gaskets and seals may leak onto the engine bay, and warning lights can illuminate for sensor issues such as O2 sensors or mass airflow sensors. Addressing leaks promptly and replacing faulty sensors can prevent more serious engine problems.



  • Oil leaks around valve covers or seals, noted as oil spots or burning smell.

  • Check engine light indicating sensor faults (O2 sensor, MAF, etc.) that may require replacement or cleaning.

  • Emissions-related fault codes that may trigger service reminders.


Keeping up with oil changes and addressing leaks early helps preserve engine health and avoids escalating repairs.


Electrical and Interior Electronics


Electrical faults and issues with interior electronics are not unusual in older luxury cars, including the IS 250. Problems can range from dashboard warning lights to battery or charging system faults and infotainment quirks. Some issues are due to aging connectors or worn relays and may be resolved with targeted component replacement or wiring checks.



  • Intermittent warning lights or fault codes from sensors and control modules.

  • Battery or charging system wear, leading to starting or accessory power issues.

  • Potential infotainment or climate-control glitches, typically resolved with wiring checks or component replacement.


Electrical problems often relate to age and use; routine electrical system checks during service help catch developing faults early.


Suspension, Brakes, and Steering


Suspension and steering components can wear with mileage, leading to clunks, tire wear, or imprecise handling. Common wear items include control arm bushings, ball joints, tie rods, and brake rotors/pads. Timely replacement not only improves ride quality but also safety and tire longevity.



  • Worn control arm bushings or ball joints causing clunking or alignment changes.

  • Brake rotor wear with pulsation or reduced stopping performance if not addressed.

  • Steering feel changes due to wear in steering linkages or suspension components.


Proactive inspection of suspension and braking systems at regular intervals helps maintain performance and prevent uneven tire wear.


Recalls and Market Variances


Like many older vehicles, IS 250s may be subject to recalls that impact safety or major systems. Recalls vary by model year and VIN, so checking the vehicle’s recall status is prudent before purchase or during maintenance.



  • Airbag inflator recalls (such as Takata-related campaigns) affecting many manufacturers, including Lexus.

  • Other VIN-specific recalls for fuel, braking, or electrical systems.


Always verify recall status and ensure any required repairs have been completed by a dealer or authorized service center.


What to Check Before Buying a Used IS 250


Before committing to a purchase, use these checks to spot potential problems and verify the car’s history. A systematic pre-purchase inspection can save time, money, and risk.


Inspection and History Basics


Obtain a full service history and verify there are records for regular maintenance, including oil changes, transmission service (if applicable), cooling system checks, and brake service. Confirm any recalls were addressed and review ownership history for prior accidents or extensive repairs.



  • Ask for complete maintenance records, focusing on transmission, oil leaks, and suspension components.

  • Obtain a vehicle history report to check for accidents or title issues.

  • Check VIN for open recalls and ensure completed recall repairs are documented.


Thorough documentation helps you assess how well the car has been cared for and what future maintenance may be needed.


Mechanical and Fluid Checks


During or before a test drive, inspect for signs of transmission issues, leaks, overheating, or abnormal noises. A professional pre-purchase inspection is highly recommended to verify engine and transmission condition and to identify any hidden problems.



  • Look for oil or coolant leaks around the engine, valve covers, and gaskets.

  • Test drive for smooth acceleration, seamless gear changes, and no shudder or delay in transmission response.

  • Inspect brakes, suspension components, and tires for even wear and adequate replacing parts.


Addressing mechanical concerns before purchase reduces the risk of unexpected repairs after buying.


Maintenance and Longevity: Keeping an IS 250 on the Road


Proactive maintenance is the best defense against common IS 250 faults. Following a structured service plan helps preserve performance, reliability, and resale value.



  1. Follow the manufacturer’s recommended maintenance schedule, using the correct fluids and parts suitable for the IS 250’s V6 engine and transmission.

  2. Maintain the transmission with timely fluid checks and any dealer-recommended software updates or servicing.

  3. Regularly inspect and service the cooling system, valve covers and gaskets, and other engine seals to prevent leaks.

  4. Inspect suspension and brakes at regular intervals; replace worn components promptly to maintain handling and safety.

  5. Keep electrical systems healthy with battery checks, charging system tests, and applying software updates when advised by a dealership.


With attentive maintenance and careful buying decisions, the IS 250 can continue to deliver the brand’s hallmark reliability and a satisfying driving experience well into later years.


Summary


The Lexus IS 250 remains a solid choice in the used-luxury market, offering dependable performance and a comfortable ride. Its most common problems tend to be age- and mileage-related—transmission behavior, engine seals, sensors, and suspension wear—rather than fundamental design flaws. A thorough pre-purchase inspection, complete service history, and adherence to a regular maintenance plan dramatically reduce the likelihood of costly surprises. Buyers should prioritize documented maintenance, verify recall completes, and test-drive to confirm the absence of transmission or drivetrain issues before purchase.
