Common 2003 Lexus Lx problems

The 2003 Lexus LX 470 is a luxury SUV known for its comfort and reliability. However, like any vehicle, it can have certain common problems that owners may encounter. Here are some of the issues reported by owners of the 2003 Lexus LX 470, based on a search of various sources

1. Exhaust system issues: Some owners have reported problems with the exhaust system, including muffler rot and burnout, as well as exhaust manifold burnout. These issues are more common in Arabic versions of the car, which are devoid of catalysts and oxygen sensors for a longer period of time.
2. Fuel pump, ignition coils, and oxygen sensors: These components can fail from time to time, requiring replacement.
3. Camshaft and crankshaft position sensors: These sensors can also fail, leading to issues with the engine's performance.
4. Cooling system: The cooling system may require updates, including the radiator and fan of thermal coupling.
5. Starter: The starter can fail, requiring replacement. Access to the starter is difficult, as it requires removing a lot of components, including the intake manifold.
6. Transmission: Some owners have reported noticeable backlash in the transmission after 200,000 to 300,000 kilometers. This is described as a knock or bump that occurs when gas is added while coasting, and is caused by total backlash in splines, joints, hub flanges, CV joints, pinion gears, and shafts in the front and rear gearboxes.
7. Front gearbox: Frequent off-road trips can quickly finish off the front gearbox. The problem was especially acute for owners of the pre-styling Lexus LX470, but was improved in later models.
8. Transfer case: The transfer case can also fail, especially after frequent off-road trips.
9. Suspension: The front suspension, which is equipped with a hydraulic suspension with ride height control, can begin to act up with age. The most common problem is with the sensors, which can fail after 200,000 to 300,000 kilometers.
10. Shock absorbers: Shock absorbers may leak after 300,000 to 400,000 kilometers.
11. Steering system: The steering system, including the steering rack and power steering pump, can require periodic maintenance.
12. Brake system: Brake calipers can turn sour, requiring replacement. The main brake cylinder can also wear out or fail, especially in restyled Lexus 470s with variable speed steering system.
13. Interior lighting: The electronic unit responsible for interior lighting, threshold lighting, sunroof control, steering wheel side windows, and the rear wiper can fail. Fortunately, it is often possible to restore it.
14. VGRS control unit: There can be failures in the operation of the VGRS control unit, which can be repaired for individual LX 470s.
15. SRS unit: A service campaign was carried out to replace the SRS unit located near the driver's seat.

It is important to note that these problems are not necessarily indicative of a lack of reliability in the 2003 Lexus LX 470. Many of these issues can be addressed with regular maintenance and repairs as needed. However, potential buyers should be aware of these common problems and consider them when evaluating the condition and value of a used 2003 Lexus LX 470.
