2018 Lexus Is problems
The Lexus IS (Japanese: レクサス・IS, Hepburn: Rekusasu IS) is a compact executive car (D-segment in Europe) sold by Lexus, a luxury division of Toyota, since 1998. The IS was originally sold under the Toyota Altezza (Japanese: トヨタ・アルテッツァ, Hepburn: Toyota Arutettsua) nameplate in Japan from 1998 (the word Altezza is Italian for 'height' or 'highness'). The IS was introduced as an entry-level sport model positioned below the ES in the Lexus lineup.
The first-generation Altezza (codename XE10) was launched in Japan in October 1998, while the Lexus IS 200 (GXE10) made its debut in Europe in 1999 and in North America as the IS 300 (JCE10) in 2000. The first-generation models were powered by a straight-six engine and available in sedan and wagon variants. The second-generation IS (codename XE20) was launched globally in 2005 with V6-powered IS 250 (GSE20) and IS 350 (GSE21) sedan models, followed by a high-performance V8 sedan version, the IS F, in 2007, and coupé convertible versions, the IS 250 C and IS 350 C, in 2008. The third-generation Lexus IS premiered in January 2013 and includes the V6-powered IS 350 and IS 250, turbocharged IS 200t/300, hybrid IS 300h and performance-tuned F Sport variants. The IS designation stands for "Intelligent Sport".
First generation (XE10; 1998)
Produced as a direct competitor to the luxury sports sedans of the leading European luxury marques, the XE10 series Toyota Altezza and Lexus IS was designed with a greater performance emphasis than typically seen on prior Japanese luxury vehicles. The engineering work was led by Nobuaki Katayama from 1994 to 1998 under the 038T program code, who was responsible for the AE86 project. Design work which had been done in 1995 by Tomoyasu Nishi was frozen in 1996 and filed under patent number 1030135 on 5 December 1996, at the Japan Patent Office. At its introduction to Japan, it was exclusive to Japanese dealerships called Toyota Netz Store, until Lexus was introduced to Japan in 2006. The Japan-sold AS200 Altezza sedan and AS300 Altezza Gita correspond to the Lexus IS 200 and IS 300 models respectively, as sold in markets outside of Japan. The Lexus IS' primary markets were North America, Australia, and Europe. The Altezza Gita was a hatchback-station wagon version sold in Japan and was known in the US and Europe as the Lexus IS SportCross. The AS300 Altezza Gita was the only Altezza with the 2JZ-GE engine; in export markets this engine was available in the sedan models as well as the Lexus IS300 Sedan.
