What Problems Does the 1991 Lexus LS 400 Have?
The 1991 Lexus LS 400, like any vehicle of its age, has common issues that owners should be aware of. One of the most frequently reported problems revolves around the climate control system. The blower motor resistors can fail, leading to inconsistent fan speeds or complete fan failure. Furthermore, the climate control amplifier, a complex electronic module, is prone to failure, resulting in erratic temperature control or the inability to adjust settings. Another area of concern is the TEMS (Toyota Electronic Modulated Suspension) system, particularly the air suspension components. These can leak or fail over time, leading to a saggy ride height or an uncomfortable, stiff ride. Repairs for TEMS can be costly, and many owners opt to convert to conventional springs and shocks. The starter motor, while generally robust, can become sluggish or fail with age. Radiator leaks, particularly at the plastic end tanks, are also not uncommon. Fuel injectors, while durable, can sometimes become clogged or fail, affecting engine performance and fuel economy. Older vehicles of this era can also experience issues with various sensors, such as the oxygen sensors or throttle position sensor, leading to check engine lights and drivability problems. While Lexus did not issue widespread recalls specifically for major mechanical failures on the 1991 model, regular maintenance is paramount. Owners often report that with consistent and proper maintenance, these cars can remain remarkably reliable. Long-term reliability is generally very high, but it heavily depends on the care and attention the vehicle has received throughout its life. There are no significant known model-year specific issues that differentiate the 1991 from very early 1990 models, as the platform was new but well-engineered from the start.
How long will the 1991 Lexus LS 400 last?
Based on owner data and maintenance habits, a well-maintained 1991 Lexus LS 400 can easily surpass 200,000 miles, with many examples exceeding 300,000 miles. The average lifespan for this vehicle, assuming diligent servicing, is often estimated at 15-20 years or more of active service. Its long-term durability is exceptional due to its robust V8 engine, solid construction, and high-quality materials. The primary weaknesses that emerge over time are typically related to aging rubber components, electrical connectors, and the aforementioned electronic control modules and suspension systems. However, the core powertrain and chassis are renowned for their longevity, making them a testament to Lexus's engineering prowess and commitment to quality.
What Technology & Safety Features are Included?
The 1991 Lexus LS 400 was a pioneer in luxury technology for its era, offering a refined and comfortable cabin experience. Built-in tech included a high-fidelity AM/FM stereo system with a cassette player, often complemented by an optional multi-disc CD changer, providing a premium audio experience for the time. Automatic climate control with micro-filter and dual-zone capability ensured consistent cabin comfort. Power-adjustable front seats with a driver's memory function were a significant luxury feature, allowing personalized settings. Power windows, power locks, and power mirrors were standard, adding to the convenience. The tilt and telescoping steering wheel also offered adjustability for driver comfort. Safety features were robust for 1991, including standard anti-lock brakes (ABS) on all four wheels, providing crucial assistance during emergency braking situations. The vehicle was equipped with front and rear crumple zones designed to absorb impact energy in a collision. Side-impact door beams provided structural integrity. While advanced driver-assistance systems as we know them today were non-existent, features like automatic headlight control enhanced visibility and convenience. In terms of crash-test ratings, official ratings from organizations like the NHTSA for this specific model year are not readily available in the modern format. However, the LS 400 was designed with a focus on occupant safety, incorporating advanced structural engineering and passive safety systems for its time. It was built to meet and exceed the safety standards of the early 1990s, and its substantial weight and robust construction contributed to its perceived safety.

1991 Lexus LS 400 Prices and Market Value
When new, the 1991 Lexus LS 400 had a Manufacturer's Suggested Retail Price (MSRP) that typically ranged from $35,000 to $45,000, depending on options and packages. This positioned it as a premium luxury sedan, competitive with established European rivals. The depreciation on the LS 400 was significant in its early years, as is common with most luxury vehicles. However, its reputation for exceptional reliability and build quality has led to a unique situation in the used market. Today, well-maintained examples can be found for anywhere from $3,000 to $10,000 or more, with pristine, low-mileage examples commanding even higher prices. Factors affecting resale value include mileage, overall condition, service history, and the presence of original documentation. Cars with impeccable maintenance records and minimal wear and tear hold their value exceptionally well for their age.
1991 Lexus LS 400 Cost of Ownership
Owning a 1991 Lexus LS 400 can be surprisingly economical for a luxury vehicle, especially considering its original price point. Insurance costs are generally moderate, often comparable to other sedans of its class and age, though this can vary by driver profile and location. Fuel costs are moderate due to its V8 engine, averaging around 15-20 mpg. Maintenance is key; regular oil changes, filter replacements, and timely addressing of minor issues are crucial and relatively affordable at independent shops. However, specialized repairs, particularly those involving the TEMS suspension or complex electronics, can be costly. Despite potential repair expenses, its long-term durability often means fewer major issues over time, making it a more economical choice than many other luxury cars from the same era if maintained properly.

How Does the 1991 Lexus LS 400 Compare to Other Sedan?
The 1991 Lexus LS 400 entered the luxury sedan market as a formidable contender against established European giants. Its primary rivals included the Mercedes-Benz S-Class (W126/W140 generation) and the BMW 7 Series (E32 generation). In terms of performance, the LS 400's 4.0-liter V8 offered smooth, potent acceleration, though perhaps not as overtly sporty as some BMW offerings. Its quietness and refinement were arguably superior to many of its contemporaries. Features-wise, the LS 400 was exceptionally well-equipped for its price, rivaling or exceeding the standard features offered by its German counterparts, especially concerning comfort and convenience items like memory seats and automatic climate control. Reliability was where the LS 400 truly shone. While Mercedes and BMW offered sophisticated engineering, they were often plagued by more complex and costly electrical and mechanical issues, particularly as they aged. The LS 400's reputation for bulletproof reliability became its defining characteristic and a major draw for buyers. Price-wise, the LS 400 offered a compelling value proposition, typically coming in at a lower price point than similarly equipped Mercedes or BMW models, making luxury more accessible. Similar alternatives from the era include the Infiniti Q45, which offered a powerful V8 and sporty handling but less emphasis on outright comfort and reliability. The Acura Legend was another strong competitor, offering a refined V8-like V6 and excellent build quality, but without the LS 400's ultimate quietness and V8 presence. For those seeking a superior luxury experience with exceptional reliability, the 1991 LS 400 remains a top choice. If a sportier driving dynamic is preferred, a well-maintained E32 BMW 7 Series or a first-generation Infiniti Q45 might be considered, but expect higher maintenance costs. The Mercedes S-Class offered unparalleled prestige but also the highest likelihood of expensive repairs.
Final Verdict: Is the 1991 Lexus LS 400 a Good Sedan?
The 1991 Lexus LS 400 is ideal for individuals seeking a supremely comfortable, reliable, and understated luxury sedan that offers excellent value, particularly in the used market. It's perfect for those who prioritize smooth, quiet cruising over aggressive performance and appreciate timeless design. It is absolutely worth buying, provided one finds a well-maintained example. Buying used is the only option, and the single, well-equipped trim level simplifies choices. Focus on examples with documented service history, especially concerning the climate control and suspension systems. For buyers willing to perform diligent maintenance or find a mechanic familiar with these cars, the LS 400 remains a remarkably rewarding and economical luxury vehicle to own, offering a taste of premium motoring without the exorbitant costs associated with newer luxury cars or less reliable contemporaries.
