When you're in the market for a new ride, especially a luxury sedan, reliability is often a top concern. The 2021 Lexus IS 350 is a strong contender in its class, known for its sleek design, engaging performance, and of course, the legendary Lexus reputation for dependability. But let's dive deeper and see what owners and experts are actually saying about the 2021 IS 350's reliability.

Digging into the Data: Reliability Ratings and Reports

Reliability ratings from reputable sources can provide valuable insights. Sites like J.D. Power and Consumer Reports offer reliability scores based on owner surveys, covering everything from minor annoyances to major mechanical failures. While specific 2021 Lexus IS 350 ratings might vary slightly across different sources, the general consensus leans toward positive. Lexus, as a brand, consistently ranks high in reliability studies, and the IS 350 generally follows suit. These ratings consider factors like the frequency of repairs, the severity of those repairs, and the overall cost of ownership. Keep in mind that these are just averages, and individual experiences can differ. It's always a good idea to read through owner reviews and forums to get a broader picture of potential issues.

Furthermore, iSeeCars.com has awarded the Lexus IS as the "Longest-Lasting Sports Sedans". They analyzed over 11.8 million cars and found that the Lexus IS is 2.2 times more likely to reach 200,000 miles compared to the average sports sedan.

What Owners Are Saying: Real-World Experiences

Beyond the numbers, hearing directly from owners provides a more nuanced understanding of a vehicle's reliability. Online forums and owner reviews are goldmines for this kind of information. Generally, Lexus IS 350 owners report positive experiences, praising the car's build quality, smooth powertrain, and lack of major issues. However, like any car, the 2021 IS 350 isn't immune to problems. Some owners have reported minor issues with the infotainment system, such as glitches or slow response times. Others have mentioned occasional problems with sensors or electronic components. It's important to remember that these are often isolated incidents and not widespread problems.

One thing that consistently comes up in owner reviews is the importance of regular maintenance. Following the recommended service schedule, including oil changes, fluid checks, and inspections, is crucial for keeping any car running smoothly and preventing potential problems down the road. Lexus vehicles, in particular, benefit from timely maintenance due to their sophisticated engineering.

Common Issues and Potential Problem Areas

While the 2021 Lexus IS 350 is generally considered reliable, it's worth being aware of some potential problem areas. As mentioned earlier, some owners have reported issues with the infotainment system. This can range from minor glitches to more significant problems requiring software updates or component replacements. Additionally, some owners have experienced issues with sensors, such as those related to the parking assist system or blind-spot monitoring. These issues are typically covered under warranty, but it's still something to be aware of.

Another potential area of concern is the car's complex electronic systems. Modern vehicles are packed with electronic components, and the IS 350 is no exception. While these systems generally function reliably, they can be susceptible to failures due to factors like voltage fluctuations, moisture, or physical damage. Regular inspections and diagnostic checks can help identify potential problems before they escalate.

It's also worth noting that the IS 350's direct-injection engine can be prone to carbon buildup over time. This is a common issue with direct-injection engines, and it can lead to reduced performance and fuel economy. Regular maintenance, such as using high-quality fuel and performing occasional fuel system cleaning, can help mitigate this problem.

Lexus Reliability: A Brand Reputation

One of the biggest factors contributing to the 2021 Lexus IS 350's reliability is the Lexus brand itself. Lexus has built a stellar reputation for producing high-quality, dependable vehicles. This reputation is based on rigorous engineering, meticulous manufacturing processes, and a commitment to customer satisfaction. Lexus vehicles are known for their longevity and their ability to withstand the rigors of daily driving. This brand reputation provides a significant degree of confidence when considering the 2021 IS 350.

Lexus's commitment to quality extends beyond the manufacturing process. The company also invests heavily in research and development, constantly seeking ways to improve the reliability and durability of its vehicles. This dedication to innovation and continuous improvement helps ensure that Lexus vehicles remain at the forefront of reliability.

Moreover, Lexus dealerships are known for their excellent service and customer support. This can be a significant advantage when it comes to addressing any potential issues or concerns. Lexus technicians are highly trained and equipped to diagnose and repair any problems that may arise, and the company's warranty coverage provides peace of mind.

Maintenance Matters: Keeping Your IS 350 in Top Shape

Even the most reliable car requires regular maintenance to stay in top condition. The 2021 Lexus IS 350 is no exception. Following the recommended service schedule is crucial for preventing potential problems and ensuring the car's longevity. This includes regular oil changes, fluid checks, filter replacements, and inspections. By staying on top of maintenance, you can help prevent minor issues from turning into major repairs.

In addition to routine maintenance, it's also important to address any potential problems promptly. If you notice any unusual noises, vibrations, or warning lights, don't ignore them. Take your car to a qualified mechanic for inspection and repair as soon as possible. Addressing problems early can often prevent them from escalating into more costly and time-consuming repairs.

Furthermore, proper driving habits can also contribute to the IS 350's reliability. Avoid aggressive driving, such as excessive acceleration and hard braking, as this can put unnecessary stress on the car's components. Smooth, controlled driving can help prolong the life of your car and reduce the risk of mechanical failures.

The Verdict: Is the 2021 Lexus IS 350 a Reliable Choice?
