The Lexus LX (Japanese: レクサス・LX, Hepburn: Rekusasu LX) is a full-size luxury SUV sold by Lexus, a luxury division of Toyota since January 1996, having entered manufacturing in November 1995. It is Lexus' largest and most expensive luxury SUV. Four generations have been produced, all based heavily on the long-running Toyota Land Cruiser SUVs. The first-generation LX 450 started production in 1995 as Lexus' first entry into the SUV market. Its successor, the LX 470, premiered in 1998 and was manufactured until 2007. The third-generation LX debuted at the New York International Auto Show in April 2007. The fourth-generation LX debuted in October 2021.

The first-generation LX 450 had a straight-six engine and seats for seven passengers. The second and third-generations had a V8 engine powertrain, a welded steel body-shell combined with full-size steel ladder frame (body-on-frame construction), and seats for eight passengers. The fourth-generation model has a twin-turbocharged V6 engine powertrain and seats for seven passengers as standard and four passengers as an option. The second-generation LX 470 shared exterior styling with the Japanese domestic market Land Cruiser Cygnus.

According to Lexus, the "LX" name stands for "Luxury Crossover". However, some Lexus importers use the backronymic name, "Luxury Four Wheel Drive".

Common 1999 Lexus Lx problems

Based on the complaints from owners of the Lexus LX 1999, here are some common problems with this car:

Throttle Position Sensor (Recall):
- The throttle position sensor in the 1999 Lexus LX 470 had a recall issue. This component is crucial for the proper functioning of the engine, as it monitors the throttle's position and sends this information to the engine control unit. A faulty throttle position sensor can lead to issues like poor acceleration, stalling, or rough idling.
Front Differential (2 Pinion):
- The 2 pinion front differential in the 1999 Lexus LX 470 was known to be weak and could blow if the vehicle was backing up uphill or when winching someone from the front. The front differential is a critical component of the drivetrain, responsible for transferring power from the engine to the front wheels. A failure in this part can result in loss of power to the wheels and potential safety hazards.
Rattling Catalytic Converter Shield:
- Owners reported issues with the rattling of the catalytic converter shield in the 1999 Lexus LX 470. The catalytic converter is an emissions control device that converts harmful pollutants in exhaust gas into less harmful emissions. A loose or damaged shield can lead to excessive noise, reduced efficiency, and potential damage to the catalytic converter.
Transmission Failures:
- Some 1999 Lexus LX 470 models experienced transmission failures. The transmission is a critical component that allows the vehicle to shift gears and transfer power from the engine to the wheels. Transmission issues can manifest as slipping gears, rough shifting, or complete transmission failure, leading to drivability problems and potential safety concerns.
Exhaust Manifold Cracks:
- Complaints included exhaust manifold cracks in the 1999 Lexus LX 470. The exhaust manifold collects exhaust gases from the engine cylinders and directs them to the exhaust system. Cracks in the manifold can lead to exhaust leaks, increased noise, reduced engine performance, and potential safety risks due to exposure to exhaust fumes.
Starter Contacts Replacement:
- Owners reported the need for replacing starter contacts around 100,000 miles in the 1999 Lexus LX 470. The starter contacts are essential for initiating the engine's starting process. Worn-out contacts can result in starting issues, such as intermittent starting, no-start conditions, or grinding noises when starting the engine.

These common problems highlight areas where owners of the 1999 Lexus LX 470 have faced challenges, emphasizing the importance of regular maintenance and prompt attention to any emerging issues to ensure the longevity and reliability of the vehicle.
