Is the 2014 Lexus IS 300 reliable?
The 2014 Lexus IS 300 was not offered in the United States; the market year typically included IS 250 and IS 350 instead. Overall, Lexus has a strong reliability record, and the 2014 IS models benefit from that reputation, provided they’ve been properly maintained. If you’re evaluating a used IS from that era, reliability tends to be favorable when the car has a solid service history.
Market reality of the 2014 IS lineup
In most regions, the 2014 IS family did not carry an IS 300 badge in the U.S.; buyers would more commonly encounter the IS 250 and IS 350. Across markets, the lineup was built around two V6 engines: a 2.5-liter V6 for the IS 250 and a 3.5-liter V6 for the IS 350, both paired with a six-speed automatic transmission. All-wheel drive was available on select trims, and the cars emphasized Lexus’s interior quality and ride comfort.
These characteristics contributed to a reliability profile that aligns with Lexus’s reputation for durable, well-built luxury cars. When shopping used, the most important factor is the individual vehicle’s maintenance history and how well it’s been cared for over time.
- IS 250: equipped with a 2.5-liter V6, generally paired with rear-wheel drive or optional all-wheel drive.
- IS 350: equipped with a 3.5-liter V6, typically offered with RWD and optional AWD.
- Transmission: both models used a six-speed automatic transmission with a focus on smooth, refined shifts.
- Interior and comfort: high-quality materials, strong cabin fit, and standard features that age more gracefully than many rivals.

In short, the 2014 IS lineup in the U.S. centered on the IS 250 and IS 350, not an IS 300. The reliability trajectory for these cars is positive, especially when the vehicle has a documented service history and no major accident damage.
Reliability profile of the 2014 IS series
Lexus’s longstanding reputation for reliability generally carries into the 2014 IS models. The brand’s engineering approach—robust engines, durable transmissions, and a focus on quality materials—helps these cars endure with lower-than-average maintenance surprises for their class. As with any aging luxury sedan, the actual reliability you experience depends heavily on how well the vehicle has been maintained and how it was driven over its life.
- Powertrain durability: the IS 250’s 2.5L and IS 350’s 3.5L V6 are known for solid long-term durability when serviced on schedule.
- Transmission behavior: a well-maintained automatic transmission should shift smoothly; occasional irregular shifts or hesitation reported by some owners can occur with older units and should be checked during a test drive.
- Electrical and interior electronics: typically reliable, but older cars can exhibit age-related dashboard or infotainment glitches; verify all functions work (nav, audio, climate controls).
- Maintenance costs and parts: generally affordable for a luxury brand relative to European rivals; routine parts and service are widely available.

Overall, a well-kept 2014 IS 250 or IS 350 offers a strong reliability proposition within the luxury midsize segment. The caveat is that any used car of this age benefits from a thorough pre-purchase inspection and verification of its service history.
What to check before buying a used 2014 IS (250/350)
Because reliability hinges on maintenance history and current condition, use these checks to guide your inspection or dealer review.
- Full maintenance history: verify regular service intervals, fluid changes, and whether recalls have been addressed.
- Engine and powertrain: inspect for oil leaks, unusual noises, and consistent oil markings; confirm there are no timing-chain issues or related failures (the 2GR-FSE uses a chain, which should remain quiet and intact with proper maintenance).
- Transmission: test drive for smooth upshifts and downshifts; note any harsh or delayed responses, and check for any stored transmission-related trouble codes.
- Suspension and steering: look for worn bushings, ball joints, control arms, and alignment issues that could indicate uneven tire wear or handling concerns.
- Brakes and tires: evaluate rotor wear, brake pad life, and tire tread; replacement costs should be anticipated for aging components.
- Electrical systems: confirm that lights, HVAC, infotainment, and sensor systems operate normally; address any warning lights on the dash.
- Recalls and campaign work: check the VIN against NHTSA or manufacturer databases to ensure all campaigns are completed.
- Rust and body integrity: inspect for signs of corrosion, especially on older examples with higher mileage.

Owner experiences and long-term value
Among owners, the IS models from this era are often praised for their refined ride and interior quality, with appreciation for long-term value when properly cared for. Prospective buyers should weigh ongoing maintenance costs and ensure the vehicle’s maintenance log supports a history of timely service.
Bottom line
For the question at hand, there was no 2014 IS 300 model in the U.S. market; the year’s entry offerings were the IS 250 and IS 350. Overall, the 2014 IS lineup inherits Lexus’s strong reliability reputation, particularly when supported by thorough maintenance and careful ownership history. A well-documented, well-maintained used IS 250 or IS 350 can deliver many years of dependable service, while a model with gaps in service or signs of neglect may encounter typical age-related concerns common to any aging luxury sedan.
Summary
In summary, the 2014 Lexus IS 300 was not a U.S. model; reliability expectations should be anchored to the IS 250/IS 350 from that period. Lexus’s brand reliability tends to be strong, and a well-maintained example of the IS 250 or IS 350 can offer solid durability and value. When buying used, prioritize a complete maintenance history, confirm recall work is up to date, and conduct a thorough pre-purchase inspection to mitigate age-related risks.
