What is the common problem with Lexus RX350?

The Lexus RX350 is a popular luxury SUV, but like any vehicle, it can experience common problems. One of the most frequently reported issues with the RX350 is related to its transmission.

Transmission Problems

Many Lexus RX350 owners have reported issues with the vehicle's transmission, particularly the 6-speed automatic transmission. Some of the common transmission-related problems include:

• Rough or jerky shifting between gears


• Delayed or hesitant acceleration when the transmission is shifting


• Transmission fluid leaks


• Premature transmission wear and failure

These transmission issues can be caused by a variety of factors, such as faulty solenoids, worn-out clutch plates, or problems with the transmission control module. In some cases, the transmission may need to be repaired or replaced to resolve the problem.

Other Common Issues

In addition to transmission problems, the Lexus RX350 has also been known to experience other common issues, including:

• Electrical system problems, such as issues with the infotainment system or dashboard displays


• Suspension problems, including worn-out shocks or struts


• Engine issues, such as oil leaks or problems with the timing chain


• Brake problems, including premature wear or issues with the brake calipers

While these issues can be frustrating for Lexus RX350 owners, many of them can be addressed through regular maintenance and prompt repairs. It's important for owners to stay on top of recommended service intervals and address any problems as soon as they arise to prevent further damage and costly repairs.

However, specific model years have a history of more reported problems, and some owners have noted issues with road noise, the infotainment system, and the automatic rear door. 
Key reliability points

• Overall dependability: The RX 350 is widely recognized for its reliability and has a reputation for being a sturdy and dependable vehicle.

What is the average lifespan of a Lexus RX350?

A Lexus RX 350's life expectancy is typically between 250,000 and 300,000 miles with proper maintenance and care, though many owners report exceeding this significantly. This translates to about 16 to 20 years of service, based on averaging 15,000 miles per year. Key factors for achieving this longevity include routine oil changes, fluid exchanges, and other scheduled maintenance, say Reddit users and CarBuzz. 
Factors that contribute to a long life

• Regular maintenance: Following the recommended service schedule is crucial. This includes regular oil changes, as well as exchanging transmission fluid and coolant, according to Facebook users and Reddit users. 
• Smart driving: Driving sensibly helps reduce wear and tear on the vehicle's components. 
• Proactive repairs: Addressing minor issues as they arise can prevent them from becoming major, costly problems down the road. 
• High-quality parts: Using high-quality parts during repairs will contribute to the vehicle's long-term health. 

Potential wear points

• While the RX 350 is very reliable, some common points to watch for include valve cover gaskets leaking oil and rear wheel bearings wearing out, note Facebook users and Reddit users. 
• Owners also recommend checking the transmission fluid level and shifting behavior, especially in high-mileage vehicles, suggests Facebook. 

What to expect from a high-mileage RX 350

• It's common to see RX 350s with 250,000 to over 300,000 miles still running strong. 
• Some owners report that while the car may still drive fine, the transmission might become sluggish around the 190,000-mile mark, but could still last for tens of thousands of miles more without repair. 
• The decision to keep driving or retire the vehicle often comes when a major repair, like an engine drop, is needed. 

What is the major problem of the Lexus RX350?

Early Lexus RX 350 releases experienced steering issues, notably power steering fluid leaks from the rack and pinion system. Not only is this a massive safety hazard – it can also be costly to repair. Unfortunately, the problem is hard to predict and can also affect vehicles with fewer than 100,000 miles on the clock.
