Overall, the 2020 Lexus RX 350 is a solidly reliable luxury SUV with strong resale value and relatively moderate maintenance costs for its class. It benefits from Toyota’s well-regarded reliability history, but some owners report infotainment glitches and occasional drivetrain quirks that are worth checking before purchase.

Reliability profile

Overview of how critics and data providers rate the RX 350’s dependability, along with typical maintenance expectations and ownership experience.

Engine and powertrain

The RX 350’s 3.5-liter V6 paired with an 8-speed automatic is known for smooth, confident performance and long-term durability. Routine maintenance—oil changes, filter replacements, and timely spark plugs—remains straightforward, and the drivetrain is generally regarded as reliable within the luxury-SUV segment.

Electronics and infotainment

Infotainment systems in the RX 350 have improved over the years, with Apple CarPlay and Android Auto availability in many 2020 models. Some owners have reported slow response, occasional screen lag, or software glitches, but these issues are typically resolved with updates or dealer service. Overall, electronics reliability is favorable for the class, though buyers should test the system during a test drive.

The RX 350 also offers a solid suite of safety features and driver-assistance technologies, which contribute to a confident ownership experience. As with any modern car, software-related issues can occur, so verifying current software versions at the time of purchase is prudent.

In terms of fuel economy, the RX 350’s efficiency is competitive for a mid-size luxury SUV, with performance-level outputs that balance power with reasonable consumption. Expect roughly mid-20s to low-20s mpg in typical mixed driving, depending on drivetrain (FWD vs. AWD) and tire choice.

Overall, the RX 350 tends to deliver dependable, predictable reliability over the long term, with ownership costs that are generally lower than many European luxury rivals—though maintenance expenses can rise as mileage increases, as with most premium vehicles.

What owners report

Consumer feedback and owner surveys commonly highlight the RX 350’s comfortable ride, refined interior, and strong resale value. While most owners are satisfied, a minority notes infotainment quirks and occasional drivetrain nuances that are worth checking on a used example.

Common issues cited

Reported concerns are typically infrequent and often addressable under warranty. The most commonly mentioned areas include infotainment system responsiveness, occasional transmission behavior during low-speed shifts, and minor cabin or road noise on certain road surfaces. Many of these issues are software-related or within the realm of normal wear and can be mitigated with timely updates and routine maintenance.

It’s important to remember that, as with any used vehicle, the frequency of issues depends heavily on maintenance history, previous ownership, and how well the car has been cared for. A well-documented service history and a pre-purchase inspection can significantly reduce the risk of hidden problems.

Buying a used 2020 RX 350: what to check

Before you buy, use these steps to assess condition, value, and potential risk on a used RX 350 from this model year.

1. Review service records and confirm all required maintenance has been performed on schedule. Look for timing belt/chain service notes (the RX 350 uses a timing chain, which typically requires inspection rather than replacement, but service history is still crucial).


2. Check for any open recalls and verify that all recall-related repairs have been completed. Use the VIN to pull a recall history from official databases or ask a Lexus dealer to run a report.


3. Inspect tires, brakes, suspension, and steering. Uneven tire wear or noisy brakes can indicate alignment issues or component wear that may affect long-term reliability.


4. Conduct a thorough test drive focusing on acceleration, transmission smoothness, and response at highway speeds. Note any shuddering, slipping, or hesitation during shifts, and test drive in both city and highway conditions.


5. Test the infotainment system and connectivity features (Apple CarPlay, Android Auto, navigation, Bluetooth) to confirm responsiveness and reliability.


6. Consider a pre-purchase inspection by a qualified mechanic who can assess undercarriage integrity, fluid leaks, and overall drivetrain health.

Following these steps helps you gauge whether a specific 2020 RX 350 is a solid buy and reduces the likelihood of hidden maintenance surprises down the line.

Summary

The 2020 Lexus RX 350 remains a strong choice for buyers seeking a reliable, comfortable luxury SUV with good resale value and a reputation for longevity. While infotainment quirks and occasional drivetrain nuances can appear, they are generally manageable and less common than in many rivals. A careful used-car inspection and thorough recall checks will help you land a dependable vehicle that should serve well for years to come.

In the end, the RX 350 offers a balanced package of reliability, comfort, and practical ownership costs that continues to appeal to buyers who prioritize long-term dependability in a luxury crossover.
