There is a significant squeal when braking at low speed in both forward and reverse. I am unsure whether this is a safety issue or not, but there is evidence online that other owners are experiencing the same issue.

Sunroof tempered glass spontaneous explosion. Loud explosion startled me and my wife, good thing the sliding roof cover was closed otherwise small pieces of sharp glasses will hit us on our head, face and shoulders. Lexus of Oakland denied any product defect and blaming a foreign "magnetic" object hit the sunroof. I was only driving 20 mph in a residential neighborhood and no cars in front of me when the sunroof exploded. No warning lamp or symptoms prior to the incident. My wife and I were scared!

My less than a year old Lexus GX550 was sitting in the driveway and the sunroof exploded. The car was not moving and it exploded outwards into a ton of pieces. The dealership claims that it is not a warrantable part. No foreign object hit the sunroof, even then it shouldn't shatter, only crack. It is my assumption that defective glass from the factory was installed into my vehicle and caused the sunroof to shatter for no apparent reason.

Vehicle experiences a persistent and abrupt harsh downshift (jerk/thud) specifically during 2nd-to-1st gear transitions when rolling to a stop. This issue persists despite the dealership performing the recommended Transmission Control Module (TCM) software update at 5,000 miles. The smooth shifting returned briefly for approximately 500 miles post-update before the abruptness returned. Additionally, there is a noticeable vibration/harmonic change in the engine as the oil reaches approximately 3,000 miles of use. Concerned that this transmission behavior is a secondary symptom of internal engine drag or main bearing stress, as documented in similar V35A-FTS engine failures. This abrupt downshifting creates a safety concern regarding predictable vehicle deceleration in stop-and-go traffic. Vehicle is currently at 6,700 miles.

On 10/7/25, the passenger side front tire malfunctioned - I currently have the tire. On 9/7/25, the drivers side rear tire malfunctioned - I no longer have that tire but I have included the receipt for the new tire I had to purchase. On 9/7/25, I was driving alone on the Florida Turnpike at night and in the rain, when the rear drivers side tire blew and was completely destroyed with multiple holes in the sidewall. Fortunately I was able to maintain control of the car, but I was stuck on the side of the highway until a Florida Road Ranger came to assist. The problem was reproduced on the morning of 10/7 when I found my passenger side front tire flat with a split sidewall. I am scheduled to take the car to the Lexus service department on 10/8/25 for inspection. The front passenger tire does not feel like rubber, it can be described as a mix of cardboard and plastic. On the evening of 9/7/25, when the rear drivers side tire blew, there was little warning, the low tire pressure warning light came on and I felt the flat tire in less than one minute. I purchased this new 2025 Lexus GX 550 in March of 2025 from JM Lexus in South Florida and these were the original tires. The car currently has 9,766 miles on it and used for commuting to work and running errands. [XXX] PT5A, 265 /55 R 20.

The driver side mirror shakes around 45 to 50 miles an hour plus. The passenger side mirror at the same speeds stays true and does not vibrate. While I am driving mostly on the highway the driver side mirror shakes or bounces up and down which distorts the images behind me. It is a safety concern where I am getting dizzy while driving. I brought the car back to the dealership Lexus of Pembroke Pines, and they replaced the entire mirror assembly, but it is having the same problem again. The car is not even two weeks old. The constant vibration is a legitimate safety concern and prevents me from safely operating this vehicle.
