Is the Lexus IS 350 reliable?
Yes. The Lexus IS 350 is generally regarded as a reliable luxury sedan, benefiting from Lexus’ long-standing reputation for durability and relatively low maintenance costs. Real-world reliability varies by model year and how well the car has been maintained, but overall it remains a solid choice for long-term ownership.
What makes the IS 350 reliable
The model’s reliability stems from a combination of a proven powertrain, high build quality, and strong dealer support. The following factors help explain its dependable reputation:
Engine and drivetrain
The IS 350 uses a robust 3.5-liter V6 that has powered Lexus models for years. When it receives timely maintenance—regular oil changes, cooling-system service, and attention to driving habits—the engine and related components tend to show long service life. The drivetrain is designed for smooth operation, and parts availability is strong thanks to Toyota-Lexus platform sharing.
Build quality and reliability culture
Lexus is known for tight tolerances, durable materials, and meticulous manufacturing. This translates into fewer rattles, solid interior integrity, and generally fewer reliability surprises compared with many peers. A supportive dealer network also helps with predictable maintenance and repairs, which reinforces long-term reliability perceptions.
Reliability by model year and common issues
Reliability patterns shift slightly across generations, but the IS 350 has consistently been viewed as dependable when properly serviced. Here are common considerations by year range:
- Older IS 350s from the early-to-mid 2010s can accumulate wear on suspension components, rubber bushings, and some electronic systems as they age. Regular upkeep becomes more important with higher mileage.
- Mid-cycle refresh models (roughly around 2017–2018) benefited from updated electronics and refinements; issues tend to be minor and often software-related.
- Recalls can affect any year; check VIN-specific recall histories via NHTSA or Lexus’ official recall database before purchasing.
In short, newer used IS 350s generally present a cleaner reliability slate, but a thorough pre-purchase inspection remains essential to verify mechanical condition and service history.
Maintenance and ownership costs
Reliability is closely tied to maintenance habits. The IS 350’s upkeep is typical for a luxury brand: predictable routine service, with costs higher than mainstream models but often lower than European rivals. Regular maintenance helps prevent surprises and preserves resale value. Specific maintenance touchpoints include:
- Oil changes every 5,000–7,500 miles with synthetic oil, per manufacturer guidelines.
- Brake service and tire replacement based on driving style and tire choice, which can influence overall ownership costs.
- Cooling-system checks, serpentine belts (where applicable), and battery health assessments as part of routine service.
- Electronics and infotainment repairs are possible as with other modern cars; a service plan can help manage these costs.
Sticking to the manufacturer’s recommended maintenance schedule and addressing recalls promptly are the most effective ways to keep the IS 350 reliable over time.
Buyer tips and sources for current ratings
To ensure you have the latest reliability outlook, consult independent ratings and verify a vehicle’s history. Helpful sources and checks include:
- Consumer Reports reliability ratings and owner satisfaction insights
- J.D. Power Vehicle Dependability Studies and related reports
- NHTSA recall database for VIN-specific history and safety campaigns
- Lexus Certified Pre-Owned programs and documented service histories
When evaluating a used IS 350, obtain a complete service history, have a trusted mechanic perform a pre-purchase inspection, and confirm that all safety recalls have been addressed.
Summary
The Lexus IS 350 stands out in the luxury compact segment for reliability, thanks to Lexus’ engineering approach, durable powertrain, and robust dealer support. While reliability can vary by model year and maintenance history, a well-cared-for IS 350 is typically a durable, low-stress ownership option. Prospective buyers should review service records, verify routine maintenance, and check for any open recalls on the specific vehicle.
