The Lexus RX has long been one of the most popular luxury SUVs in the US, offering a blend of comfort, reliability, and luxury features. The 4th generation RX, sold from 2016 through 2022, built on this reputation with updated styling, refined technology, and a smoother driving experience compared to the previous generation. However, even a vehicle known for its reliability has its share of issues. Below are some of the most common issues on the Lexus RX 4th generation SUV.
Infotainment System
While Lexus improved its tech during this generation, many owners found the infotainment system difficult to use. The touchpad-style interface introduced in some models can be overly sensitive and distracting while driving. Connectivity problems with Apple CarPlay or Bluetooth have also been noted, causing issues despite an otherwise comfortable interior.
Transmission and Shifting
Drivers have reported transmission hesitation, particularly when accelerating from a stop or at lower speeds. The 8-speed automatic transmission can sometimes feel sluggish or display rough gear changes. Although not a widespread failure, it can affect drivability and lead to complaints about performance compared to other SUVs in its class.
Suspension Wear and Ride Quality
Over time, the Lexus RX may develop squeaks, clunks, or uneven ride quality linked to suspension wear. Control arm bushings and struts are components that can wear earlier than expected, especially on vehicles driven in rougher conditions. While these issues don’t typically compromise safety, they can ruin the vehicle’s comfortable ride feel.
Battery and Electrical System
Some owners have reported shorter-than-expected battery life and occasional electrical malfunctions, such as warning lights appearing without an obvious cause. In hybrid models, concerns have also been raised about the 12v auxiliary battery health. Keeping up with inspections and replacing weak batteries before they fail helps prevent unexpected breakdowns.
Air Conditioning and HVAC
The air conditioning system has been another point of concern, with reports of weak cooling performance or unpleasant odors coming from the vents. These issues are often related to clogged cabin air filters or moisture buildup in the HVAC system, both of which require periodic maintenance to address.
Why Regular Maintenance Matters
Although the Lexus RX is known for its reliability, regular upkeep is key to preventing small issues from becoming major problems. The Lexus RX maintenance schedule outlines important intervals for services such as oil changes, transmission inspections, brake service, and filter replacements. By sticking to these recommended service milestones, owners can extend the life of their SUV while ensuring that its luxury driving experience remains intact.
