What owners report

Tl* the contact owns a 2006 lexus gx43, equipped with nexen tires n5000 245/40/r18 xl. When the traffic light changed to green and traveling approximately 15 mph, the passenger side front tire blew up. The contact lost control of the vehicle and went over a sidewalk and damaged the rear passenger side tire.
Tl* the contact owned a 2006 lexus gs430. While driving approximately 5 mph, the contact drove through a small puddle of water. The vehicle accelerated and the contact was unable to control the steering. The brake pedal was stiff and the contact could not steer or brake to control the vehicle.
After the vehicle was driven and parked for approximately 10-15 minutes, the contact noticed flames underneath the hood. The fire was extinguished by a friend. The fire department was not notified. The contact stated that the fire may have originated from the battery compartment. The vehicle was not diagnosed.
Door hinge on vehicle looks to have manufacture problem but I do not see a recall for this issue it is break through the metal and creating a hole and may need to be welded of some sort or a new door.
My check pcs and vbs lights came on and went off. I continue to drive and my breaks worked fine for a week. Driving home on a side street crossing a bridge and a piercing beep came on and would not go off. I think that was an indicator ro pull off the road.
Front right wheel makes loud banging sound. Started when the car had about 70,000 miles on it. Then came a horrible squeaking sound. This occurs constantly when driving and especially when turning the wheel. I replaced the lower control arm bushing in june.
The contact was driving 70 mph when the vehicle started to vibrate violently. The contact then took the vehicle to the dealer who stated that he would give the contact new rims. The dealer stated that the contact would have to pay for the tires.
Last saturday, I brought it to the dealer for the second time to fix the squealing brakes. I was told that lexus is working on the problem but no solution is available for me at this time. On sept 27, I was told that they could not duplicate the problem.
