The 2017 Lexus LS is a full-size luxury sedan designed for buyers who prioritize quiet comfort, high-end materials, and long-term dependability over sporty handling. It sits at the top of Lexus’s sedan lineup and competes with flagship models like the Mercedes-Benz S-Class and BMW 7 Series, often appealing to owners who want premium features with fewer headaches. For 2017, the LS remains part of the fourth-generation LS (XF40), which ran through the end of this body style before the next-generation redesign arrived for 2018. If you want a traditional, smooth-riding luxury sedan with a reputation for durability, the 2017 LS is a strong fit.

1) Proven V8 power: The LS 460 uses a 4.6L V8 (1UR-FSE) with an 8-speed automatic transmission, delivering smooth acceleration and refined highway manners. 2) AWD availability: The LS 460 is offered in rear-wheel drive or all-wheel drive, with AWD versions typically paired to a 6-speed automatic—popular for drivers in snow-belt states. 3) Long-wheelbase option: The LS 460 L adds rear legroom and a more limousine-like feel, making it ideal for frequent passengers or executive transport. 4) Premium cabin and ride quality: Expect a quiet interior, supportive seats, and a comfort-first suspension tune that excels on long trips. 5) Luxury tech and safety: Many 2017 LS models include features like navigation, a premium audio system, parking sensors, a backup camera, and available driver-assist tech depending on package.

Shoppers looking up 2017 Lexus LS reliability will generally find it considered above-average for a flagship luxury sedan, but no vehicle is perfect. Here are some 2017 Lexus LS problems and common issues owners and technicians most often mention: 1) Suspension wear and ride concerns (often 60,000–120,000 miles): The LS is heavy, and components like control arm bushings, ball joints, and shocks/struts can wear, leading to clunks over bumps, uneven tire wear, or a less-controlled ride. Models equipped with more complex suspension setups can be more expensive to refresh. 2) Brake actuator/ABS system concerns (mileage varies): Some owners report ABS/brake warning lights, unusual brake feel, or actuator-related faults. Diagnosis matters here because symptoms can also be caused by wheel speed sensors or low-voltage battery issues. 3) Sticky or cracking dash/interior trim (age/climate-related): In hot climates, some drivers report interior surfaces becoming sticky, shiny, or cracking over time. It’s not usually a drivability issue, but it affects long-term cabin presentation. 4) Electronic and convenience feature glitches (typically intermittent): Issues like parking sensor faults, infotainment quirks, or power feature hesitation can appear with age. These are often solvable with diagnosis, battery health checks, and addressing water intrusion or connector corrosion if present.
