Lexus RX 330 2004
In comparison to other years in this lineup, the 2004 Lexus RX 330 is less reliable. A common problem is a transmission problem. The transmission has been having problems, including delayed shifting, slipping gears, and even completely failing. Repairs for these problems are usually expensive, so buying a 2004 model is a risk.

Unless these issues are addressed promptly, they can cause expensive repairs. Besides this, reports indicate that the navigation system malfunctions and dashboard lights flicker.
Lexus RX 330 2006
Lexus’s 2006 RX 330 has also been found to be unreliable. As with the 2004 model, transmission problems remain a significant concern. The transmission frequently slips gears and fails suddenly for many owners. Another concern is suspension problems. A rough driving experience is caused by prematurely worn shocks and struts.
The 2006 model also suffers from electrical glitches. Navigation systems are commonly reported to be faulty and dashboard electronics to malfunction. People who rely on advanced features may not enjoy their ownership experience as a result of these problems.
Problematic Years’ Common Issues
Transmission Failures
Several transmission failures have been reported in Lexus RX 330 models from 2004 to 2006. Owners report that their transmissions are slipping gears, responding slowly when shifting, or, in severe cases, completely breaking down. There have been some instances of these problems occurring earlier than 80,000 miles. Transaxles are expensive and often require expensive repairs or replacements.
A number of these failures can be attributed to insufficient lubrication, excessive overheating, or excessive wear of internal components. Maintaining the vehicle regularly can reduce the risks associated with it, but some vehicles may be unable to avoid repairs due to inherent defects. The transmission system must be thoroughly inspected before purchase if you are considering a 2004 or 2006 RX 330.
Engine Problems
A number of engine-related issues also plague both the 2004 and 2006 models. An issue that is commonly reported is excessive oil consumption. Often, owners have to top off their oil more often than they expected. A low oil level can damage or ruin an engine if left untreated.
In addition, there have been reports of stalling, sometimes with no warning signs. When it happens while driving, it can be particularly dangerous.
When piston rings and valve seals wear out, excessive oil consumption is often the result. Oil changes and regular monitoring may be helpful in preventing these problems in vehicles susceptible to these problems, however a substantial investment may be required over the long term.
Electrical Glitches
Issues with the electrical system were also prevalent in both problematic years. Drivers may be distracted by flickering or failing dashboard lights. Owners who use navigation systems for convenience are often frustrated by malfunctions. Electrical systems can be very expensive to diagnose and repair, even when they seem minor.
