What Problems Does the 2017 Lexus GS 450h Have?

The 2017 Lexus GS 450h generally enjoys a strong reputation for reliability, consistent with Lexus' brand image. However, like any vehicle, there are a few areas owners have noted over time.

Frequently Reported Issues:
  • Hybrid Battery Life: While hybrid batteries in Lexus vehicles are known for their longevity, they are a complex and expensive component. Although issues are rare in the 2017 model year, a potential future concern for any high-mileage hybrid is the eventual need for battery replacement. Symptoms of a failing battery can include reduced power, lower fuel economy, and illuminated warning lights.
  • Infotainment System Glitches: Some owners have reported occasional minor glitches with the Lexus Enform infotainment system, such as freezing or slow response times. These are typically software-related and may be resolved with updates.
  • Brake Wear: While not a widespread issue, some owners have noted that regenerative braking systems in hybrids can sometimes lead to uneven brake pad wear. Regular inspections are recommended.

Recalls:
It is always advisable to check for any outstanding recalls specific to a vehicle's VIN. For the 2017 Lexus GS 450h, recalls have been issued for various reasons, including potential issues with the airbag system, fuel pump, and power steering. These recalls are typically addressed by dealerships at no cost to the owner.

Long-Term Reliability Concerns:
Beyond the specific points above, the GS 450h is built on a robust platform. The powertrain is well-engineered, and the build quality is excellent. For those who maintain their vehicle according to Lexus' recommended schedule, long-term reliability is generally very high. The primary long-term cost consideration will likely be the potential replacement of the hybrid battery pack, which can be several thousand dollars, though this is often many years down the line and not guaranteed.

How long will the 2017 Lexus GS 450h last?

The 2017 Lexus GS 450h is built for longevity, and with proper maintenance, owners can reasonably expect to get 200,000 to 250,000 miles or more out of the vehicle. Many Lexus vehicles, especially hybrids, are known to exceed these figures. Consistent oil changes, adherence to the hybrid system service schedule, and timely replacement of wear items are crucial. Long-term durability is a strong suit, with the core mechanical components and interior materials holding up exceptionally well. The primary weakness over extended periods would be the eventual, albeit often distant, cost of hybrid battery replacement and potential aging of electronic components. However, overall, its long-term prospects are excellent.

What Technology & Safety Features are Included?

The 2017 Lexus GS 450h offers a sophisticated array of technology, entertainment, driver-assistance, and safety features, reflecting its luxury sedan status.

Built-in Tech and Entertainment:
Standard features typically include a 12.3-inch high-resolution display for the Lexus infotainment system, controlled via the Lexus Remote Touch interface (a mouse-like controller). This system encompasses:
  • AM/FM/HD Radio
  • CD/DVD player
  • SiriusXM Satellite Radio
  • Bluetooth connectivity for audio streaming and hands-free calling
  • USB and auxiliary audio jacks
  • A backup camera
An optional upgrade was the premium 17-speaker Mark Levinson surround sound audio system, offering exceptional acoustic quality for audiophiles. A voice-activated navigation system with integrated apps was also a popular option.

Driver-Assistance and Safety Features:
The 2017 GS 450h came equipped with a comprehensive suite of standard safety features, including:
  • 10 airbags (including front, side, knee, and rear side airbags)
  • Vehicle Stability Control (VSC)
  • Traction Control (TRAC)
  • Anti-lock Braking System (ABS) with Electronic Brake-force Distribution (EBD) and Brake Assist (BA)
  • LED headlights, taillights, and daytime running lights
  • Tire Pressure Monitoring System (TPMS)
Lexus also offered a highly advanced optional Pre-Collision System (PCS) with Pedestrian Detection, which could automatically apply brakes if a frontal collision was imminent and the driver did not react. Other available driver-assistance technologies included:
  • Dynamic Radar Cruise Control (DRCC)
  • Lane Departure Alert (LDA) with Steering Assist
  • Intelligent High-Beam headlights
  • Blind Spot Monitor (BSM) with Rear Cross-Traffic Alert (RCTA)
  • Front and rear parking sensors

Crash-Test Ratings:
The 2017 Lexus GS, including the 450h model, received excellent crash test ratings from the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS). It typically earned a 5-Star Overall Safety Rating from NHTSA and was often a TOP SAFETY PICK+ designation from IIHS, signifying top marks in various crashworthiness and front crash prevention categories.

When new, the 2017 Lexus GS 450h had an MSRP typically starting in the high $60,000s, often reaching into the $70,000s with optional packages. As a luxury hybrid, its initial price reflected its advanced technology and premium features. Currently, used 2017 GS 450h models can be found ranging from approximately $25,000 to $35,000, heavily depending on mileage, condition, and location. The GS 450h experiences a significant depreciation from its original price, which is common for luxury vehicles. However, Lexus vehicles, particularly hybrids, tend to hold their value better than many competitors due to their reputation for reliability and lower running costs. Factors positively affecting resale value include low mileage, a comprehensive maintenance history, and the presence of desirable optional features.

However, potential long-term repair costs can be higher for hybrid-specific components like the battery if they require replacement outside of warranty, though this is infrequent.

How Does the 2017 Lexus GS 450h Compare to Other Sedan?

The 2017 Lexus GS 450h competes in the competitive mid-size luxury sedan segment against rivals like the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6. In terms of performance, the GS 450h offers a unique blend of potent acceleration from its hybrid powertrain and a smooth, refined ride, often prioritizing comfort over outright sportiness compared to its German counterparts. The BMW 5 Series, for example, often provides a more engaging driving experience.

Regarding features, the GS 450h is generously equipped with luxury amenities and advanced safety tech, comparable to its rivals, though its infotainment interface might feel slightly less intuitive or modern than some.

Where the GS 450h truly shines is in reliability. Lexus consistently leads the automotive industry in reliability ratings, and the GS 450h is no exception. Its German rivals, while offering exceptional engineering, can be more prone to costly repairs as they age.

Similar or Better Alternatives:
  • Infiniti Q70 Hybrid: A direct competitor offering a similar hybrid powertrain and luxury appointments, though often with slightly less refined handling and interior.
  • BMW 5 Series Hybrid (e.g., 530e iPerformance if available, or older ActiveHybrid models): For those prioritizing driving dynamics and a more modern tech interface, the BMW 5 Series, especially its hybrid variants, is a strong contender, though potentially less reliable and more expensive to maintain.
  • Lexus GS 350: If hybrid efficiency isn't a top priority, the gasoline-powered GS 350 offers similar luxury and reliability with a more traditional powertrain and potentially slightly sharper handling, often at a lower used price.
The GS 450h remains a standout choice for buyers who value exceptional reliability, strong fuel efficiency in a luxury sedan, and a comfortable, well-appointed interior.

Final Verdict: Is the 2017 Lexus GS 450h a Good Sedan?

The 2017 Lexus GS 450h is an ideal choice for discerning buyers who prioritize refined luxury, exceptional reliability, and impressive fuel efficiency in a sedan format. It's perfect for commuters looking to save on gas without sacrificing performance or comfort, and for those who appreciate Lexus' reputation for long-term durability.

It is absolutely worth buying, especially on the used market. The significant depreciation from its new price makes it a great value proposition. It's best purchased used, as buying new would have incurred substantial initial depreciation. Given that the 2017 model year represents the GS 450h as a well-established hybrid, seeking a well-maintained example with lower mileage will offer the best ownership experience. Opting for a GS 450h ensures a premium driving experience backed by Lexus' legendary dependability, making it a wise and economical luxury car purchase.
