The contact owns a 2025 Lexus TX350. The contact stated that while driving 50 MPH, the brake pedal was depressed and felt spongy, and the vehicle failed to respond as intended, causing the braking distance to be extended. The vehicle was taken to the dealer, where the contact was informed that the brakes were in good working condition; however, the failure persisted.

I would just like to say that the info instrument panel in my Lexus does not light up satisfactory to see when there’s daybreak. I think this is a safety hazard when you can’t see the numbers because of the sunshine. I think this is a safety issue that should be addressed by Lexus anytime you can move the instrument cluster info and you cannot read the numbers then there is a problem. I haven’t seen where many people have complained about it, but I do know that mine is not the only one that has this problem. Thank you.

While my 2025 Lexus TX was parked in my residential garage, the vehicle suddenly locked itself with my [XXX] and [XXX] children and my phone inside. The doors had been unlocked prior to placing them in the vehicle. Without warning, the vehicle locked all doors and windows. The key fob failed to unlock the vehicle electronically or manually. My husband and I attempted for over 30 minutes to gain access while the children remained trapped inside before calling the dealership for technical help. They instead transferred us to Lexus roadside assistance. Lexus roadside assistance advised calling

Basically, the instrument cluster lighting is very, very poor. Very difficult to read when driving, especially in a day break. You must turn off your daylight running lights to make it a little bit brighter. This is a problem.

03/02/20Component: VEHICLE SPEED CONTROL

While stopped in traffic with my foot firmly on the brake pedal, my vehicle began accelerating forward unexpectedly. The vehicle seemed "possessed". It was as if the gas pedal was fully on the ground while my foot was still on the brake, so the car was lurching and seemed to be fighting itself. The vehicle continued moving forward and would not stop despite sustained and hard brake pressure. I was rapidly closing distance on the vehicle in front of me and narrowly avoided a collision by inches. The vehicle only stopped after I shifted it into park and then I shut the car off. This was a terr
