The Lexus GS (Japanese: レクサス・GS, Rekusasu GS) is an executive car (E-segment in Europe) manufactured and marketed by Lexus across four generations — launched in 1991 as the Toyota Aristo in Japan and as the Lexus GS for markets outside the JDM beginning in February 1993. It continued with the Toyota Aristo name for the Japanese market until January 2005.

Lexus marketed the GS as a performance sedan competing in the mid-luxury class, between its compact executive IS and large/flagship LS. The GS shared its chassis with one of Toyota's longest-running nameplates, the Toyota Crown premium sedans until 2011.

The GS featured six-cylinder engines and rear-wheel drive, with a V8 engines offered forall generations, and all-wheel drive and hybrid versions debuted in 2005. Previously, all-wheel drive versions were already made available in the Japanese-market S140 series Aristo. The first two generations had a Japanese domestic market equivalent, the Toyota Aristo (aristo is Greek for "the best"), which was sold from 1991 until the Lexus marque's domestic debut in 2005. Though largely identical in exterior and interior design, the GS and the Aristo differed in their engine and transmission combinations as well as equipment packages. The GS name stands for Grand Sedan. However, some Lexus importers use the backronymic name, Grand Sport.

The first generation Lexus GS began sales in the United States, Europe and selected Asian markets in 1993. It was originally introduced with an inline-six engine and exterior bodywork designed by Italdesign Giugiaro. The second generation model premiered in 1997, using a new platform, in-house styling, and adding a V8 version for the first time outside Japan. The third generation GS, which premiered globally for the 2006 model year, was produced in V6, V8, and hybrid versions, the latter known as the GS 450h. The third generation models were the first GS sedans to be badged as such in the Japanese domestic market.

The fourth generation Lexus GS premiered in August 2011 at the Pebble Beach Concours d'Elegance, where models introduced included the V6-powered GS 350, hybrid GS 450h, and performance-tuned F Sport variants. A lower-displacement V6 model, the GS 250, premiered at the Auto Guangzhou Exhibition in November 2011, targeted at Asian and European markets. In some markets such as North America and Asia, the GS shares the mid-size sedan category in the Lexus lineup with the front-wheel drive ES, serving as its rear-wheel-drive counterpart.

The GS was replaced in Europe by the Lexus ES from December 2018. The seventh generation ES is the first to be sold in Europe, replacing the GS in spite of being a front-wheel drive car. It went on sale from September 2018 in Russia, Turkey and other CIS markets and from December 2018 in Western and Central Europe. Production ended in August 2020.

Common 2002 Lexus Gs430 problems

The Lexus GS430, produced from 2001 to 2007, is known for its luxurious interior and advanced technology features. However, like any vehicle, it has its share of common problems that owners should be aware of. Here are some of the most frequently reported issues:

Engine Misfires: Engine misfires are a common problem in the 2001-2005 models of the Lexus GS430. This issue can be caused by a variety of factors, including faulty spark plugs, ignition coils, and fuel injectors. In some cases, engine misfires can be a sign of more serious problems, such as a damaged catalytic converter or a malfunctioning engine control module.
Oil Consumption: Some owners of the 2006-2007 models of the Lexus GS430 have reported that their vehicles consume excessive amounts of oil. This issue can be caused by worn piston rings or valve guides, which can allow oil to leak into the combustion chamber. In some cases, oil consumption can be reduced by using higher quality motor oil or by replacing worn or damaged engine components.
Transmission Problems: Transmission problems are a common issue in the 2001-2005 models of the Lexus GS430. This issue can be caused by a variety of factors, including low transmission fluid levels, worn clutch plates, and damaged torque converters. In some cases, transmission problems can be resolved by replacing worn or damaged components or by performing a transmission flush.
Suspension Issues: Suspension issues are a common problem in the Lexus GS430, particularly in the 2001-2005 models. This issue can be caused by worn or damaged suspension components, such as bushings, struts, and springs. In some cases, suspension issues can be resolved by replacing worn or damaged components or by performing a suspension alignment.
Electrical Problems: Electrical problems are a common issue in the Lexus GS430, particularly in the 2006-2007 models. This issue can be caused by a variety of factors, including faulty wiring, blown fuses, and malfunctioning sensors. In some cases, electrical problems can be resolved by replacing faulty components or by performing a diagnostic test to identify the root cause of the issue.
Steering Issues: Steering issues are a common problem in the Lexus GS430, particularly in the 2001-2005 models. This issue can be caused by worn or damaged steering components, such as rack and pinion assemblies, tie rods, and power steering pumps. In some cases, steering issues can be resolved by replacing worn or damaged components or by performing a steering alignment.
Brake Problems: Brake problems are a common issue in the Lexus GS430, particularly in the 2001-2005 models. This issue can be caused by worn or damaged brake components, such as brake pads, rotors, and calipers. In some cases, brake problems can be resolved by replacing worn or damaged components or by performing a brake fluid flush.

To diagnose and troubleshoot these issues, it's important to first identify the year, model, and engine type of the car. For example, early models of the GS430 (2001-2005) were more likely to experience engine misfires and transmission issues, while later models (2006-2007) had more problems with oil consumption and power steering. Additionally, the engine type (3UZ-FE) can also affect the type of problems and solutions needed. Common engine issues include carbon buildup, oil consumption, and misfires. Diagnosing these issues may involve a visual inspection for leaks and worn parts, check engine light codes, or compression and leak down tests. Overall, the Lexus GS430 was a reliable and luxurious car that offered advanced technology and features. However, like any car, it had its fair share of problems that owners should be aware of. Regular maintenance and troubleshooting can help identify and fix these issues, ensuring a safe and enjoyable driving experience.

Jo Osinski 2025-01-06

This car has exceeded every expectation I had for it. It's not only fun to drive but also very luxurious and comfortable. I've even surprised other cars on the road with the speed and acceleration of the GS several times!
Delbert Mosciski 2024-11-01

Terrific road car! It's very powerful and really fun to drive. The only issue you might encounter is a minor display glitch with the radio LCD window, but otherwise, the car has performed perfectly.
Emanuel Littel 2024-10-27

What a fantastic car! It's even faster than a Boxster, 540, and E430. I found it to be more comfortable than the BMW, and the control layout is better than the others. In my experience, the build quality is also superior. I had a great experience at JM Lexus, which is THE dealership to go to. The BMW dealer was a bit snotty and insisted on coming along for the test drive, while the Mercedes dealer wanted my credit card before allowing me to test drive the car (ridiculous!). On the other hand, the Lexus representative was very friendly and said, 'Take it out for the day,' which I did!
Dan Klein 2024-10-20

When I decided to purchase a new car, I had a few specific goals in mind. I was looking for a V8 powered FR car with a bold and assertive attitude. And let me tell you, I found exactly what I was looking for! Now, every time I see a red light, I can't help but feel excited. Why, you ask? Because when I step on the gas, my 3700LB car takes off with incredible urgency. While I don't recommend burning expensive Bridgestone tires, I must say that the quality of my Lexus is truly phenomenal. It is the epitome of luxury, with 300 powerful ponies at my service.
Colin Mohr 2024-09-23

The only reason I am parting with my car is because I need to seat more than 5 people. I absolutely love the GS430 and would buy another one in a heartbeat. It has been a fantastic car and I have nothing but positive things to say about it.
