When you're in the market for a new ride, especially a luxury sedan, reliability is often a top concern. Nobody wants to be stuck on the side of the road or constantly shelling out cash for repairs. So, let's get straight to the point: How reliable is the 2021 Lexus IS 350? We'll explore what makes a car reliable, dig into the Lexus reputation, and see what owners and experts are saying about this particular model.

What Makes a Car Reliable?

First off, what do we even mean by "reliable"? It's not just about whether the car starts every morning. A truly reliable car has a few key characteristics:

• Infrequent Repairs: This is the big one. A reliable car shouldn't need constant trips to the mechanic for anything beyond routine maintenance.
• Low Maintenance Costs: Even when maintenance is needed, the cost should be reasonable. Parts should be readily available and not excessively expensive.
• Longevity: A reliable car should last for many years and rack up a lot of miles without major issues. We're talking well over 100,000 miles, and ideally closer to 200,000 or more.
• Consistent Performance: A reliable car performs consistently well in various conditions. No weird quirks or unpredictable behavior.

Why Reliability Matters

Reliability isn't just a nice-to-have; it's crucial. Imagine relying on your car for daily commutes, family road trips, and everything in between. A reliable vehicle offers peace of mind, knowing you can depend on it to get you where you need to go without unexpected breakdowns or costly repairs. This dependability translates to less stress and more freedom, allowing you to focus on your journey rather than worrying about your car's performance. Furthermore, a reliable car retains its value longer, making it a smart investment in the long run. You'll save money not only on repairs but also potentially get a better resale price when you decide to upgrade. In essence, reliability is about more than just the car; it's about the security and confidence it provides in your daily life.
