Maintenance, costs, and ownership experience

Maintenance expectations

The RX 350 uses a timing chain on its 3.5-liter V6, which generally reduces major maintenance needs compared with belt-driven engines. Routine service—oil changes, filter replacements, brake upkeep, and tire rotation—remains essential, and maintenance costs for a luxury SUV are higher than mainstream brands. Lexus’s dealer network and reliability history often help keep ownership costs predictable.

Fuel economy and performance

The 2017 RX 350 delivers a smooth and comfortable ride with adequate power for daily driving and highway merging. EPA estimates for the RX 350 are typically around 20 mpg city and 27 mpg highway for most configurations, with all-wheel drive slightly reducing highway efficiency. Real-world fuel economy varies with driving style and conditions.

Resale value and ownership experience

Lexus RX models have a reputation for holding value well, aided by reliability, a strong brand image, and widespread service support. For owners, predictable maintenance costs and a satisfying ownership experience contribute to favorable long-term ownership metrics compared with some peers in the luxury SUV segment.

What to check if you're buying used

If you’re shopping for a used 2017 RX 350, use this checklist to gauge reliability and overall condition before you buy.

1. Obtain a full vehicle history report and verify any recalls have been completed.


2. Have the electrical system and infotainment unit tested for glitches or lag.


3. Check for smooth operation of the transmission during a test drive, including gear shifts and acceleration responsiveness.


4. Inspect the suspension, brakes, and tires for even wear and any unusual noises.


5. Review maintenance records to confirm regular oil changes, filter replacements, and service at authorized centers.


6. Request a pre-purchase inspection by a qualified technician familiar with Lexus vehicles.

These steps help ensure you’re evaluating a well-maintained example and reduce the risk of unexpected repairs after purchase.

Summary

The 2017 Lexus RX 350 stands out in the used-luxury market for its reliability, durable V6 powertrain, and strong ownership experience. While no used car is free from potential issues, the RX 350’s track record tends to beat many competitors in its class, especially for buyers who prioritize long-term dependability and a calm, comfortable driving experience. With careful pre-purchase checks and up-to-date recalls addressed, a well-cared-for 2017 RX 350 can still be a solid pick in today’s market.

Is the 2017 Lexus IS 350 worth buying?

Edmunds' Expert Rating. The 2017 IS 350 sits at the top of the automaker's entry-level IS luxury sedan lineup. It cedes sport-sedan ground to others in the segment, but its robust V6 power, high-quality interior trimmings and surprisingly smooth ride still make for a satisfying sedan.

How long will a 2017 Lexus RX 350 last?

A 2017 Lexus RX 350 can last between 250,000 and 300,000 miles or more with proper maintenance, which includes regular oil changes, fluid flushes, and timely part replacements. Factors like climate, driving conditions, and maintenance consistency significantly influence its lifespan, with some owners reporting over 300,000 miles.
 
Factors influencing longevity

• Maintenance: Adhering to a consistent maintenance schedule is crucial. 
  • Regular oil changes are essential. Some recommend changing the transmission fluid and filter every 50,000 miles to extend its life. 
  • Timely replacement of other fluids and filters is also key. 
• Driving habits: How you drive and where you drive affects wear and tear. 
  • City driving or harsh weather can put more stress on the vehicle than highway driving. 
• Repairs: Addressing issues promptly will prevent minor problems from becoming major ones. 
  • For example, some 2017 models had issues like timing chain cover leaks, which can be costly if not covered by a warranty or addressed promptly. 

What you can expect

• Engine and transmission: The Lexus RX 350 is known for its reliable engine. However, some mechanics suggest that the engine can last much longer than the transmission. Changing the transmission fluid is a key step in extending the life of both components. 
• Major components: As the vehicle ages, certain parts will naturally wear out and need replacement, such as suspension components, brakes, and battery. 
• Long-term reliability: While the average car lasts around 175,000 miles, the Lexus RX 350 often surpasses this significantly, and a well-maintained one can last much longer.
