When you're considering a new car, especially a luxury sedan like the 2021 Lexus IS 350, reliability is probably high on your list. After all, nobody wants to deal with constant repairs and maintenance headaches. So, let's dive into what makes a car reliable and see how the 2021 Lexus IS 350 stacks up.

Defining Automotive Reliability

First, it's important to understand what we mean by "reliable." In the automotive world, reliability refers to how consistently a car performs without major mechanical issues or failures. It's about more than just avoiding breakdowns; it also includes the frequency of minor repairs, the longevity of components, and overall owner satisfaction. Several factors contribute to a vehicle's reliability, including:

• Build Quality: The quality of materials and how well the car is assembled.
• Engineering Design: A robust and well-thought-out design reduces the likelihood of failures.
• Maintenance: Regular and proper maintenance is crucial for any vehicle's longevity.
• Component Quality: Using high-quality parts ensures they can withstand the rigors of daily driving.

Reliability Ratings and Reports

To get an objective view of a car's reliability, we often turn to expert ratings and reports from reputable sources. Here are a few that provide valuable insights:

• J.D. Power: J.D. Power conducts extensive surveys of car owners to assess their experiences with their vehicles. Their Vehicle Dependability Study (VDS) looks at problems experienced during the past 12 months by original owners of three-year-old vehicles. A lower score indicates higher reliability.
• Consumer Reports: Consumer Reports gathers data from its members about their vehicles, covering everything from minor annoyances to major repairs. They use this data to predict the reliability of new cars.
• RepairPal: RepairPal analyzes repair data to provide reliability ratings for various makes and models. They also estimate the average annual repair costs and the likelihood of needing unscheduled repairs.

Diving Deeper: Lexus Reliability Over the Years

To really understand the reliability of the 2021 Lexus IS 350, it helps to look at Lexus's track record as a brand. Lexus has consistently ranked at the top of reliability surveys for decades. This reputation isn't just by chance; it's the result of meticulous engineering, rigorous testing, and a commitment to quality.

Historical Data

Looking back, Lexus vehicles from the late 1990s and early 2000s are still on the road today, often with hundreds of thousands of miles on the odometer. This longevity is a testament to the brand's durability and reliability. Even older models, like the Lexus LS 400, are known for their bulletproof reliability.

Modern Lexus Models

In more recent years, Lexus has continued to uphold its reputation for reliability. Models like the ES, RX, and GX have consistently earned high marks from J.D. Power, Consumer Reports, and other reputable sources. While newer vehicles have more complex technology, Lexus has managed to integrate these features without sacrificing reliability.

The Lexus Philosophy

Lexus's commitment to reliability is deeply ingrained in the company's philosophy. From the design stage to the manufacturing process, every aspect of a Lexus vehicle is carefully considered to ensure durability and longevity. This includes using high-quality materials, employing advanced manufacturing techniques, and conducting rigorous testing to identify and address potential issues.

Comparing the Lexus IS 350 to Competitors

When evaluating the reliability of the 2021 Lexus IS 350, it's helpful to compare it to its competitors in the luxury sedan segment. Some of the IS 350's main rivals include the BMW 3 Series, Audi A4, and Mercedes-Benz C-Class.

BMW 3 Series

The BMW 3 Series is known for its sporty handling and engaging driving dynamics. However, in terms of reliability, the 3 Series has historically lagged behind the Lexus IS. BMWs tend to have more frequent and costly repairs, according to data from J.D. Power and Consumer Reports.

Audi A4

The Audi A4 offers a stylish interior and advanced technology features. While Audi has made strides in improving its reliability in recent years, the A4 still doesn't quite match the Lexus IS in terms of dependability. Audi's complex electronics and turbocharged engines can sometimes lead to issues.

Mercedes-Benz C-Class

The Mercedes-Benz C-Class is renowned for its luxurious appointments and sophisticated styling. However, like BMW and Audi, the C-Class tends to be less reliable than the Lexus IS. Mercedes-Benz vehicles often have higher repair costs and more frequent maintenance needs.

Why Lexus Stands Out

One of the key reasons why Lexus consistently outperforms its competitors in reliability is its conservative engineering approach. Lexus tends to avoid using overly complex or unproven technologies, preferring to stick with tried-and-true designs. This approach reduces the risk of failures and ensures that Lexus vehicles are built to last.
