Rancho Palos Verdes, CA
Today our GX 550 OT+ brakes felt weird as we left the house. Had to apply much more pressure to get the brake to engage. After about a 10 mile commute it became much worse barely stopping the vehicle. A warning came up stating "Power Brake Low, Safely stop the vehicle and call dealer", paired with a constant chime that wouldn't shut off. A brake light indicator also came up in the cluster. Luckily, I was able to get right into the dealer and they are currently looking at it. This vehicle just has a 15K scheduled maintenance/inspection last week. All fluids topped, and brakes pads had plenty of pad left. Anyone else experience this issue yet? Much appreciated.

Scary. Interested to hear diagnosis. Something caused a brake fluid leak

Sorry to hear. Just a reminder that in a true emergency, if you pull and hold the parking brake button up for a few seconds it will engage.
 
If I were you, I would be highly suspicious of the recent 15K mile service performed at your dealer. Particularly interesting is the way they spun the story, e.g. bolt /rubber line. During the so-called inspection the tech most likely introduced FOD near the brake lines or damaged the line with his light or tools. I would have requested pictures of the damages and would bet that it was induced by incompetent technicians. A visual inspection would have been sufficient and topping off brake fluid, if needed. My dealer takes videos of anything out of the ordinary and sends them to me for review. What you experienced is entirely unacceptable.

You are being too trusting with your dealer. There are many other dealers in the CA area; I would be taking my GX elsewhere the next time.

We get videos of every single service from the technician in real time like most Lexus dealers but thank you for the tip on what may have possibly happened with technician.
