The 2017 Lexus RX 350 remains a popular choice in the luxury SUV segment, celebrated for its plush ride, refined interior, and dependable V6 performance. While the model generally enjoys a solid reputation for reliability, a thorough review of 2017 lexus rx 350 problems reveals specific issues owners should be aware of. Understanding these common complaints and factory fixes can help prospective buyers make a more informed decision and ensure their driving experience remains exceptional.
Common Mechanical and Electrical Issues
When examining 2017 lexus rx 350 problems, several recurring mechanical and electrical themes emerge from owner reports and manufacturer communications. The most frequently cited issues involve the infotainment system, power liftgate mechanisms, and various sensor malfunctions. Addressing these concerns early is crucial for maintaining the vehicle's premium feel and preventing more significant, costlier repairs down the line.
Owners often report glitches with the navigation and audio interface, which can become slow or unresponsive. The power liftgate, a convenient feature, sometimes fails to open or close correctly due to wiring or motor issues. Furthermore, the check engine light may illuminate due to faulty oxygen sensors or loose gas caps, requiring diagnostic scanning to pinpoint the exact cause.
Infotainment and Power Liftgate Concerns
The centerpiece of the cabin for the 2017 model year is the touchscreen infotainment system, which, while feature-rich, has been known to present challenges. System freezes, slow response times, and occasional failure to recognize USB devices are problems that can disrupt the driving experience. Lexus has issued over-the-air updates and extended warranty coverage for these specific malfunctions, highlighting the brand's commitment to resolving known defects.
The power liftgate, a signature luxury feature, can occasionally malfunction. Owners have experienced issues where the gate fails to open automatically or shuts prematurely during closure. This problem is often linked to the liftgate's control module or wiring harness, and a visit to the dealership for a software update or component inspection is the recommended solution.
Brake System and Steering Complaints
Beyond electronics, some 2017 RX 350 owners have noted concerns related to the braking and steering systems. A common complaint involves a grinding or vibrating sensation when applying the brakes, which can indicate warped rotors or worn brake pads. Regular brake pad replacement, a standard maintenance item, should be monitored closely to prevent damage to more expensive rotor components.
Another reported issue is a clunking or knocking noise emanating from the front suspension, particularly noticeable when driving over uneven road surfaces. This noise often points to worn control arm bushings or ball joints. While not a sudden failure, these worn components can affect handling and should be inspected during routine service intervals to ensure safe driving dynamics.
Proactive Maintenance and Model Year Variations
It is important to note that not every 2017 Lexus RX 350 will experience these problems. Manufacturing quality control improved over the model year, meaning issues found in early production vehicles might not appear in later ones. Furthermore, the severity and frequency of problems can vary significantly from one vehicle to another, depending on driving habits and maintenance history.
Proactive maintenance is the single best defense against these common issues. Adhering strictly to the factory-recommended service schedule, using high-quality fluids, and addressing warning lights promptly can mitigate the risk of major repairs. For buyers considering a used model, a pre-purchase inspection by a qualified mechanic familiar with Lexus vehicles is the most effective way to identify any hidden problems and verify the car's overall condition.
