Lexus Sc400 problems
The Lexus SC (Japanese: レクサス・SC, Rekusasu SC) is a grand tourer that was retailed by Lexus (a luxury vehicle division of Toyota), and built from 1991 until 2010. It features a front-engine, rear-wheel-drive design and seating for up to four passengers. The first-generation SC debuted as the V8-powered SC 400 in 1991, and the I6-powered SC 300 was added in 1992. Both first-generation models were produced until 2000. The second-generation model, the SC 430, went into production in 2001. The SC 430 features a hardtop convertible design and a V8 engine. The first-generation SC was largely styled in California at Calty, and the second-generation SC was mainly conceived at design studios in Europe.
In Japan, the related third-generation Toyota Soarer, with which the first-generation SC originally shared body design and multiple components, featured a separate line-up of vehicle configurations and different powertrains. The third generation Soarer sport coupe, largely identical to the SC 430, was superseded by its Lexus counterpart in Japan when the Lexus marque débuted there in 2005. The SC was the sole coupé in the Lexus lineup until the arrival of the IS C. According to Lexus, the SC designation stands for Sport Coupe. The LC replaced the SC lineup in 2017.
First generation (Z30; 1991)
1991–2000
In the early 1990s, following the début of Lexus, automotive press reports indicated a forthcoming Full-size Lexus coupé to compete with other luxury GT coupés of other marques like the Mercedes-Benz CL, Acura Legend coupe and later the Acura CL, Mazda Eunos Cosmo, Buick Riviera, Cadillac Eldorado, Lincoln Mark VIII, Jaguar XJS, Bentley Continental, Maserati Shamal/Ghibli, Ferrari 456 and BMW 8 Series coupe. At that point, Toyota had no genuine luxury coupés in its model range. A coupe would complement the successful Lexus flagship model, the V8-powered, rear-wheel drive LS 400 sedan. The coupé was going to be targeted towards the American market, and the development effort for its exterior design was handed over to the Calty Design Research center in California in 1987.
The American Calty design team took a different approach to designing the car, using plaster molding shapes to design the body, and working three-dimensionally instead of the traditional 2-D sketch approach. As described by design chiefs Denis Campbell and Erwin Lui, the result was a car that was based on "emotion and feeling" rather than linear aesthetics. The resulting design possessed almost no straight edges, and produced a drag coefficient of Cd=0.31. The production design concept by Lui was approved at the beginning of 1989, resulting in Lui being sent back to Japan for 4 months to assist in completion of the production design. According to automotive journalist Bill Russ, the SC design was considered influential among automotive designs of the time.
Production of the Soarer started in April 1991 at the Motomachi plant in Toyota, Aichi, with the Lexus SC produced alongside the Soarer at a second Higashi Fuji plant at Susono, Shizuoka. Motomachi-sourced cars lasted until April 1997. The Lexus SC platform was used to develop Toyota's next generation Supra, both vehicles were manufactured in the same plant.
The SC 400 débuted on 1 June 1991 in the United States as a 1992 model. The SC 400's 4.0 L V8 1UZ-FE, the same engine as used in the LS 400, was reported to have cost over US$400,000,000 in research and development. The engine sits behind the front axles, which makes it a front mid engine rear wheel drive vehicle. The SC 400 was honored as the Motor Trend Import Car of the Year for 1992. It also made Car and Driver magazine's Ten Best list from 1992 through 1996.
In July 1992, the SC 300, a smaller-engined version of the SC 400, premiered in the United States. The SC 300 was equipped with a 3.0 L inline 6 2JZ-GE. Lexus' traction control system, TRAC, was offered as an option.
The first-generation SC lasted in production until 7 July 2000, over nine years, quite long compared to the other cars of the 1990s. Even with the SC's long production cycle, only minor exterior changes were made. New tail lighting and a modified spoiler design was part of the mid-cycle vehicle refresh. A front grille was added in 1996, along with a redesigned front bumper, side skirts and rocker panels. The SC 400 produced 250 hp (186 kW)/260 lb⋅ft (353 N⋅m) from 1991 to 1995. The original 1991–1997 engines for the 2JZ-GE-powered SC 300 were rated at 225 hp (168 kW)/210 lb⋅ft (285 N⋅m). The output of the SC 300 was 5 horsepower more than the equivalent engine used in the Toyota Supra.
In 1996, the SC 400's 1UZ-FE engine design was upgraded to 260 hp (194 kW) from 250 hp (186 kW). These engines were coupled with a 4-speed automatic transmission on both the SC 300 and SC 400 models. A 5-speed manual transmission was only offered on the SC 300 from its debut until 1997.
By the end of the decade, North American SC sales began dwindling due to the lack of significant design updates since the car's introduction and marketplace changes that led to loss of interest in coupes.
In 1997 (1998 model year), both the SC 300 and 400 were upgraded with VVT-i and thus the ratings were raised to 290 hp (216 kW)/300 lb⋅ft (407 N⋅m) of torque for the SC 400 and 225 hp (168 kW)/220 lb⋅ft (298 N⋅m) of torque for the SC 300. Tests conducted on the new engines showed an acceleration for the SC 400 for years 1992–1995 of 0–60 mph in 6.9 seconds, years 1996–1997 in 6.7 seconds, and years 1998–2000 in 6.1 seconds. For the SC 300 an acceleration 0–60 mph in 6.8 seconds with the 5-speed manual and 7.2 seconds with the 4-speed automatic for all years. This 1997 upgrade included the replacement of the four-speed automatic on the SC 400 to a five-speed unit. With the replacement of the five-speed unit those models also got a new differential with a final drive of 3.27 improving both fuel economy and top speed.
Sales of the automatic transmission SC 300 and SC 400 models formed the vast majority of models purchased. The Lexus SC 400 was never officially sold in the British Isles, but many examples found their way across the Atlantic as personal imports.

Common Lexus Sc400 problems
Based on the complaints from owners of the Lexus SC400, several common problems have been identified:
- Power Steering Issues:
- The power steering pump in the Lexus SC400 is prone to leaks, particularly from the high-pressure line and the body of the pump. These leaks can lead to power steering fluid dripping onto the alternator, causing damage.
- Solution: Rebuilding the power steering pump can address these leaks. It involves replacing the o-ring inside the pump to prevent further leaks onto the alternator.
- Starter Replacement Challenges:
- The starter in the Lexus SC400 is located underneath the intake manifold, making it difficult to access and replace. This can be a time-consuming task due to the numerous bolts involved.
- Solution: While replacing the starter is manageable, it requires patience and careful handling, especially if the intake and EGR components are intact.
- Hydraulic Fan Problems:
- The SC400 comes with a hydraulically actuated fan that can develop leaks over time, leading to cooling system issues.
- Solution: Addressing leaks in the hydraulic fan system is crucial to prevent overheating and maintain proper engine cooling.
- Window Regulator Failures:
- Window regulators in the Lexus SC400 are prone to failure, causing issues with raising and lowering windows. Replacing these regulators can be challenging due to the need to remove various components.
- Solution: When encountering window regulator problems, it is essential to address them promptly to avoid inconvenience and potential safety hazards.
- Door Handle Clips Breakage:
- The door handle clips in the SC400 are known to break, preventing the door from being opened from the outside. This can lead to additional damage to the door lock mechanism.
- Solution: Replacing the broken door handle clips is necessary to restore proper functionality and prevent further damage to the door locking system.
- Fuel Pump ECU Bypass:
- The fuel pump ECU in the Lexus SC400 may stop providing the necessary voltage to the fuel pump, affecting its performance. Owners often resort to bypassing the ECU to ensure the fuel pump operates at full power.
- Solution: Jumping two wires together to bypass the fuel pump ECU can help maintain proper fuel pump function in the SC400.
These common problems with the Lexus SC400 highlight the importance of regular maintenance and prompt repairs to ensure the longevity and reliability of the vehicle.

This car is incredibly reliable, has trouble-free operation, a comfy and spacious interior (even for backseat passengers), a very smooth transmission, a quiet ride, a sporty suspension, and the styling is sexy. One day, it will be a classic car. Additionally, my engine mechanic informed me that this engine is good for 400,000 miles without a rebuild and has never seen an engine failure on these cars. It's good to know!

Vehicle year: 1993
I have had this car for three years now. I got it as a graduation gift and I have loved every minute of driving it. Even though it's over ten years old and I live in Scottsdale surrounded by Rolls, Benz, and other luxury cars, I still get a lot of attention in it. I really can't see myself ever selling it. And have I mentioned the interior? I absolutely love it all!

Vehicle year: 1999
This car is a fantastic combination of luxury and performance. The fast but quiet V8 engine provides exceptional handling, and the ride is great for a sport coupe. While traction can be an issue in snow conditions, it's still an excellent choice for those who want a high-performance vehicle.

Vehicle year: 1994
I bought this car in 1997 when it had 70K miles. Now, with 137K miles, I still love it! It's a powerful and well-handling sport coupe. I always wanted a Lexus since it first debuted as a 1990 model. Finally, I could afford a used one and I'm happy I did. I've only had usual used-car stuff, no major problems. I plan to drive it until the wheels fall off, or until my 13-year-old nephew is old enough to drive (whichever comes first)...and I truly believe my car will last far beyond my nephew's 16th birthday!!!

The parts for this vehicle can be quite expensive (for example, a stripped gear in the passenger seat can cost up to $1000). While it could handle better, this vehicle is still enjoyable to drive. Although the quality of the interior accessories is rather poor, I do appreciate the interior design.

I hope you're doing well! I just wanted to share my experience with my mother's Lexus 400SC. I bought it with only 55,000 miles on it and I was so excited to drive it! Unfortunately, I've had some trouble with the battery. It's been in the shop three times and no one can seem to find the drain on the battery. I've had to replace the battery three times in the past two years. Despite these issues, I still love driving it. However, it hasn't been the most reliable car I've ever owned. Thanks for listening!
