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.

Car’s brake fluid leaked out of the brake lines into the master cylinder or brake booster resulting in significant loss of brake fluid to the system and a hazardous driving condition.

The contact owns a 2025 Lexus GX 550. The contact stated that while driving at various speeds, the hood of the vehicle was fluttering up and down. The vehicle was taken to the dealer; however, the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 4,865.

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.
