Analysis

What Problems Does the 2020 Lexus GS 350 Have?

The 2020 Lexus GS 350, being the final year of its generation, generally benefits from the accumulated refinements of its production run. As such, major widespread mechanical issues are not commonly reported for this specific model year. However, like many vehicles, some owners have noted specific, albeit less frequent, concerns.

One area that sometimes draws comment is the infotainment system. While functional, its interface might feel a bit dated compared to newer, more touch-responsive systems in competing vehicles. Issues like occasional glitches or slow response times have been mentioned by a small number of users.

Another point that can be subjective is the ride quality and handling. While Lexus is known for comfort, some drivers seeking a more aggressive, sporty feel might find it slightly less dynamic than its German counterparts. However, for those who prioritize a smooth and serene ride, this is often seen as an advantage.

Recalls for the 2020 model year are relatively few and typically address minor issues that were often resolved with software updates or simple component replacements. For example, recalls might have been issued for fuel pump issues or specific sensor malfunctions that could affect emissions or engine performance. It is always recommended to check the NHTSA website for any specific recalls applicable to a particular vehicle identification number (VIN).

In terms of long-term reliability, the Lexus GS line, including the 2020 model, is expected to be exceptionally robust. Lexus consistently ranks at the top for reliability surveys, and the GS 350 benefits from this brand-wide dedication to engineering durability. The powertrain, in particular, has proven to be very dependable over many years and miles when properly maintained.

How long will the 2020 Lexus GS 350 last?

Based on owner data and typical luxury sedan usage, the 2020 Lexus GS 350 can reasonably be expected to serve reliably for 10-15 years or 150,000 to 200,000 miles, with proper and consistent maintenance. Lexus vehicles are renowned for their longevity, and the GS 350 is no exception. The V6 engine and 8-speed automatic transmission are robust. Long-term durability is a strong suit, though potential weaknesses over time might include wear on interior components due to the premium materials and the eventual need for more significant suspension or brake component replacements as mileage increases. Regular fluid changes and adherence to the maintenance schedule are crucial for maximizing its lifespan.

What Technology & Safety Features are Included?

The 2020 Lexus GS 350 comes equipped with a solid suite of technology, entertainment, driver-assistance, and safety features.

Tech and Entertainment: Standard features typically include a 12.3-inch infotainment display screen operated via a mouse-like controller on the center console. This system includes standard navigation, Bluetooth connectivity for audio streaming and hands-free calling, HD Radio, SiriusXM satellite radio, and voice command functionality. A 12-speaker Lexus Premium Sound System is also standard, offering a good audio experience. Optional upgrades could include a Mark Levinson 17-speaker surround sound audio system for audiophiles. Apple CarPlay integration was introduced for the 2020 model year, a significant upgrade for smartphone users. Android Auto is notably absent.

Driver-Assistance and Safety Features: Lexus Safety System+ is standard on the 2020 GS 350. This comprehensive package includes:
  • Pre-Collision System with Pedestrian Detection
  • All-Speed Dynamic Radar Cruise Control
  • Intelligent High Beams
  • Lane Departure Alert with Steering Assist
  • Lane Keeping Assist
Additional standard safety features often include a rearview camera, blind-spot monitoring with rear cross-traffic alert, parking sensors, and 10 airbags. Optional features could include a panoramic view monitor for enhanced parking visibility.

Crash-Test Ratings: The 2020 Lexus GS 350 generally performed well in crash tests. The National Highway Traffic Safety Administration (NHTSA) awarded it an overall 5-star safety rating. The Insurance Institute for Highway Safety (IIHS) gave it top ratings of "Good" in most crashworthiness tests, earning it a designation as a Top Safety Pick. These strong ratings underscore the vehicle's robust construction and effective safety systems.

Insurance for a 2020 Lexus GS 350 is moderately priced, reflecting its status as a Sedan with strong safety ratings and
reasonable repair costs.

How Does the 2020 Lexus GS 350 Compare to Other Sedan?

The 2020 Lexus GS 350 competed in the premium mid-size sedan segment against formidable rivals like the BMW 5 Series, Mercedes-Benz E-Class, Audi A6, and Genesis G80.

Performance: The GS 350's 311-hp V6 offers strong acceleration and a smooth power delivery. However, rivals like the BMW 5 Series and Audi A6 often provide more engaging driving dynamics, sharper handling, and a wider array of potent engine options (e.g., turbocharged inline-sixes or V8s). The GS 350 leans more towards comfortable cruising than outright sportiness, especially outside the F Sport trim.

Features: Lexus consistently equips its vehicles with generous standard features, and the GS 350 is no exception with its large infotainment screen, comprehensive safety suite, and premium materials. However, its infotainment interface can feel less modern than the systems found in German rivals, which often boast more intuitive touchscreens and advanced connectivity. The Genesis G80, at a similar or lower price point, also offers an impressive array of standard technology and luxury appointments.

Reliability: This is where the GS 350 truly shines. Lexus has a legendary reputation for long-term reliability, consistently outperforming its European competitors in most consumer surveys. The GS 350 is expected to be significantly more dependable over the long haul than the BMW 5 Series or Mercedes-Benz E-Class, which can be more prone to expensive repairs as they age. The Genesis G80 also offers strong reliability, but Lexus often holds a slight edge.

Price: The GS 350 was generally priced competitively, often undercutting similarly equipped German rivals when new. On the used market, its strong resale value means it might command a higher price than some competitors with lower reliability ratings, but the long-term ownership cost savings can offset this.

Recommendations:
  • Similar Alternative: The Genesis G80 offers a compelling blend of luxury, performance, and value, with strong reliability to match.
  • Sportier Alternative: If driving dynamics are paramount, consider a BMW 5 Series (e.g., 530i or 540i) or an Audi A6. Be prepared for potentially higher maintenance and repair costs.
  • More Value-Oriented Alternative: While discontinued, a well-maintained previous generation Lexus GS is still a solid choice.
The 2020 GS 350 remains an excellent choice for those prioritizing reliability, comfort, and a refined driving experience over sporty dynamics and the absolute latest in infotainment tech.

Final Verdict: Is the 2020 Lexus GS 350 a Good Sedan?

The 2020 Lexus GS 350 is ideal for buyers seeking a dependable, comfortable, and luxurious sedan that prioritizes smooth cruising and bulletproof reliability over razor-sharp handling. It's an excellent choice for professionals, empty nesters, or anyone who values peace of mind and a serene cabin. It is absolutely worth buying, particularly on the used market, as it offers exceptional value for a premium sedan that should serve reliably for many years.

Buying a used 2020 GS 350 is generally recommended over purchasing new, given its discontinuation. Opting for the F Sport trim offers a sportier aesthetic and slightly more engaging driving dynamics without sacrificing too much comfort. Look for well-maintained examples with lower mileage to maximize its already impressive long-term potential and minimize the risk of unexpected repair costs.
