Lexus Gx problems
The Lexus GX (Japanese: レクサス・GX, Hepburn: Rekusasu GX) is a mid/full-size luxury SUV sold in North American and Eurasian markets by Lexus, a luxury division of Toyota. The GX is based on the Toyota Land Cruiser Prado, from which it derives its off-road capability. Lexus introduced the first generation, known as the GX 470 in 2002, and subsequently became the third SUV to enter the Lexus lineup. A full-time four-wheel drive system is standard with low-range gearing. The 4.7-liter V8 engine in the GX 470 was the same as used on the larger LX 470. The firm next introduced the second-generation model in 2009, badged GX 460 to reflect the switch to a 4.6-liter V8 engine. Lexus later released a lower displacement GX 400 in 2012 for the Chinese market, with a 4.0-liter V6 engine. The third-generation model introduced in 2023 uses the GX 550 moniker with a twin-turbocharged 3.4-liter V6 engine and GX 550h with a turbocharged hybrid electric 2.4-liter four-cylinder engine.
As of 2024, the GX is positioned between the larger LX or TX and the smaller RX. Though it is thought the GX has always been larger than the RX, from 2015 to 2022, the RX is slightly longer and slightly wider than the GX and therefore the GX was considered smaller. All GX production has occurred at the Tahara plant in Japan, alongside the Land Cruiser Prado and the export-minded Toyota 4Runner.
Some countries classify the GX as a full-size vehicle (e.g., Australia), while some classify it as a mid-size vehicle (e.g., US), depending on local regulations.
