Experienced a 4,000-mile journey in my 2025 Lexus GX 550 on Trail, found the vehicle packed with power, yet the infotainment system exhibited a disconcerting habit of resetting my personal settings arbitrarily.
In the world of luxury SUVs, the Lexus GX550 stands out for its blend of off-road capability and refined comfort. However, like any vehicle, it's not without its quirks. Here's a rundown of some common issues and potential fixes for the GX550, focusing on its tires, infotainment system, and suspension tuning.
Tires
While specific tire-related issues are less common, maintaining the GX550's tires is crucial for preserving their lifespan and handling characteristics. Regular tire rotations, alignments, and inspections are recommended. Some owners have reported no unusual issues beyond normal tire care and occasional maintenance like spark plug replacement and oil changes.
Infotainment System
The infotainment system in the GX550 often receives mixed reviews. A common complaint is the center infotainment screen's tendency to reboot while driving, which can be distracting or inconvenient. Some users suggest settings adjustments, such as turning off surround sound modes, to improve the audio system's behavior. There's no official fix, but monitoring for software updates from Lexus and rebooting the system might help. Persistent issues might require dealer intervention.
Suspension Tuning and Cabin Noise
As a body-on-frame SUV, the GX550 can produce unusual noises, especially around the driver’s side B-pillar and rear cabin area. These noises include clicking or ticking sounds over uneven roads or at highway speeds. Lexus service has attempted fixes by adding sound-deadening material, which helps somewhat but some noise may remain. This is partly attributed to the EKDSS working and the nature of the vehicle’s build. Suspension tuning itself is praised for balancing comfort and off-road capability, but some body flutter on the hood has been observed by owners, which may be a minor quirk.
Additional fixes mentioned in broader GX550 troubleshooting include checking and replacing fuses, the clutch relay, and testing the compressor for related mechanical issues.
These represent the more commonly discussed quirks based on recent owner experiences and community reports as of 2025. It's important to note that every vehicle, including the Lexus GX550, may exhibit unique issues, and this article serves as a general guide rather than an exhaustive list of potential problems.
In other news, the GX550's interior is described as functional but not flashy, with a truck-like ride. The vehicle's twin-turbo V6 engine delivers rich, low-end torque and a seamless midrange surge, even under heavy load. The GX550's sturdy, body-on-frame construction preserves its true off-road heritage without compromising luxury refinement.
Some owners have applied Adam's ceramic/graphene coating to their vehicles, finding it makes cleaning easier. Others have installed XPEL windshield PPF at a cost of $600. The GX550's quiet, well-sealed cabin pairs genuine off-road capability with Lexus-grade comfort, making both mountain climbs and urban commutes feel equally serene.
However, the air conditioning system is described as adequate but not great, and it experiences inconsistencies. One owner reported a break-in oil change at 1,200 miles and subsequent oil changes scheduled at 5K, 10K, etc. The Lexus GX550 features a remote start system that is described as "ridiculously dramatic" but functional.
As always, it's essential to consult your local Lexus dealership or a certified mechanic for any vehicle-specific concerns or questions. Happy driving!
