The 2018 Lexus LS is broadly regarded as a reliable choice in the luxury full-size sedan class, with strong long-term durability and solid owner satisfaction. As a six-year-old used model, it benefits from Lexus’ reputation for reliability, but buyers should expect typical luxury-car maintenance costs and the potential for occasional model-year quirks. This article breaks down reliability ratings, common issues, maintenance considerations, and buying tips for a used LS from this year.
To understand reliability for the 2018 LS, it helps to look at independent ratings, real-world owner feedback, and the specifics of the model year. The LS lineup generally performs well in reliability surveys, though some electronics and drivetrain nuances have surfaced in owner reports. Below is a concise, sourced-style overview of what to know if you’re considering a 2018 LS as a used purchase.
Reliability ratings in context
Independent sources typically place the 2018 LS above average for reliability within the luxury segment. The following notes capture the gist of what those sources convey.
Consumer Reports stance
Consumer Reports commonly rates Lexus models, including the LS, as having above-average predicted reliability for their class. While individual model-year scores can vary, the 2018 LS generally earns praise for durability and consistent performance over time.
J.D. Power stance
J.D. Power’s quality and reliability assessments for Lexus—across its lineup and especially for flagship models like the LS—tend to be favorable. The LS benefits from Lexus’ broader reputation for solid long-term reliability and comparatively lower frequency of severe mechanical failures within its segment.
In short, reliability ratings for the 2018 LS align with the brand’s reputation: solid overall, with room for improvements in areas common to modern luxury cars, such as electronics and software updates.
Overall, reliability is strong for the 2018 LS within its class, though electronics and software updates can require attention as vehicles age. As with any used luxury sedan, a thorough pre-purchase inspection and a complete service history are key to confirming condition.
Common issues reported by owners
Owners generally report strong durability, but there are patterns worth noting for a used 2018 LS. The list below highlights items that have shown up in owner feedback and recall campaigns.
- Transmission behavior: Some LS 500 models have occasional shifting quirks or hesitation, especially as the 10-speed automatic adapts to driving style.
- Infotainment and electronics: Reports of touchscreen lag, navigation glitches, or occasional software freezes are more common than drivetrain problems.
- Electrical and sensor glitches: Electronics-related nuisance lights or sensor warnings can appear, though they don’t typically indicate a mandate for major repairs.
- Recalls and campaigns: Like many modern vehicles, the LS 2018 can be subject to recalls (airbags, software updates, etc.). Ensuring all campaign work is up to date is important.
- Ride hardware and comfort items: In some cases, suspension or ride-quality concerns are reported, often tied to aging nibs like worn bushings or tires rather than a systemic failure.
These issues are not universal and tend to be more about age and maintenance history than a inherent flaw in every vehicle. A well-documented service history and a pre-purchase inspection can help separate typical wear from recurring problems.
Maintenance costs and ownership experience
Maintenance and ownership experience for a used 2018 LS tends to reflect the expectations for a luxury European-like sedan with Japanese reliability: higher than mainstream brands, but typically manageable within the Lexus ecosystem. The list below outlines what buyers should anticipate.
- Higher routine maintenance costs: Premium parts, fluids, and labor for a Lexus LS translate to costs higher than average non-luxury sedans.
- Tire and brake expenses: Premium tires and brake components are standard on the LS, which can raise annual upkeep compared with mass-market sedans.
- Depreciation and resale value: The LS generally holds its value better than many rivals, reflecting Lexus reliability and strong brand perception in the luxury segment.
- Hybrid considerations: If you opt for the LS hybrid variant, battery/electric components introduce additional maintenance considerations, though reliability remains solid when properly serviced.
- Warranty and service history: A clear service history and remaining warranty (if any) can significantly ease ownership costs and confidence in used purchases.
In practice, owners who stay on top of regular maintenance and address recalls promptly tend to report satisfying ownership experiences with fewer surprise repair costs.
Buying tips for a used 2018 LS
To maximize reliability and minimize risk when shopping for a 2018 LS, follow these checks and steps.
- Check service history and recall status: Look for a complete maintenance log and confirmation that all campaign repairs have been completed.
- Pre-purchase inspection by a qualified technician: Have a professional inspect powertrain, electronics, suspension, brakes, and tires for signs of wear or potential issues.
- Test-drive with emphasis on transmission and electronics: Notice smooth gear changes, minimal lag in infotainment responses, and stable idle and cruise behavior.
- Verify tire condition and alignment: Uneven wear or cupping can indicate alignment or suspension concerns that could affect reliability.
- Check for open campaigns and software updates: Ensure navigation, Bluetooth, and vehicle software are current; address any outstanding updates.
These steps help ensure you’re not inheriting a maintenance burden that could undermine the LS’s reliability advantages.
Bottom line
The 2018 Lexus LS remains a strong, reliable choice in the luxury segment, with a track record of durability and high owner satisfaction. While it shares the high maintenance costs typical of luxury sedans and can exhibit electronics or early-tech quirks, overall reliability is solid if the car has been well maintained and any recalls have been addressed.
For prospective buyers, the best path to reliability is a thorough pre-purchase inspection, a complete service and recall history, and a vehicle in good maintenance condition with up-to-date software. A well cared-for 2018 LS can deliver many years of refined performance with fewer surprises than you might expect from a car in this class.
Summary: The 2018 Lexus LS generally offers strong reliability for a luxury sedan, backed by Lexus’ brand reputation and owner satisfaction. As with any used luxury vehicle, its long-term reliability hinges on maintenance history, timely recalls, and attentive care to the vehicle’s electronics and powertrain.
