GX Height Control Issue

I'm a bit stressed. I've got a 2023 Lexus GX hybrid with about 228998 km on it. Recently, a warning light popped up on the speedometer indicating some kind of height control issue. I've noticed the low beams seem off, either shining too high or too low, and the vehicle definitely feels uneven – the front seems lower than the rear. To top it off, the ride is super bumpy. I scanned for codes, and sure enough, there's an error stored related to the height control system. Has anyone experienced anything similar? I'm worried it's going to be a huge repair bill!

A 2023 Lexus GX hybrid exhibited a height control issue, indicated by a warning light and symptoms such as uneven vehicle stance, misaligned low beams, and a bumpy ride. The problem was traced to a defective control rod in the leveling sensor, which was initially overlooked during a self-inspection. After professional diagnosis and replacement of the faulty control rod, the vehicle's issues were resolved, restoring normal operation.

I had something similar happen with my GX, though it wasn't a hybrid. Same warning light and the uneven stance. I'd check the leveling sensor first, specifically the control rod. Is the bumpy ride constant, or does it seem to get worse at certain speeds or on uneven roads?

Thanks for the tip! Where exactly is this leveling sensor located, and what should I be looking for on the control rod? Any tips on how to inspect it? And yeah, the bumpy ride is pretty much constant, maybe a little worse on rough roads.

Okay, if the bumpiness is constant, it definitely points to a problem with the suspension system itself. The leveling sensors are usually connected to the suspension arms near each wheel. Look for a small arm or rod connecting the sensor to the suspension. If it's broken or disconnected, that would explain the issues you're seeing. Honestly, though, given all the symptoms, I'd recommend taking it to a trusted workshop to get a proper diagnosis. It could be more complicated than just the sensor rod.

So, after checking the control rod myself, it looked fine. But, based on your advice, I took it to a local shop, and turns out, the control rod WAS indeed defective! They replaced it, and now everything is working perfectly. The total repair cost was around 110€. Thanks a lot for your help; I really appreciate it!
