| Front Suspension Control Arm problems |
My car was parked inside of the parking structure of my condo. When my wife started the car and tried to move the car backward to leave the parking structure, about a second later, with huge boom noise, the car just collapsed. The rear tire on driver side was leaning outside and it seems either ball joint or upper or lower control arm is broken and the car is off the balance with rear driver side of the body frame is lowered due to this. My wife panicked and we were all shocked what has happened to this car. Especially when we have 18-month old daughter and it was very very serious safety issue because if she was driving on a freeway going on 65-70 miles per hour and if this happened, we would've not been here. I have taken many photos and videotaped it to have some kind of evidence before moving the vehicle or towing. After the incident, I have notified the local Lexus dealer's service department and explained it to the service dept manager what has happened and also notified my insurance company about this whole issue. I cannot imagine how this kind of incident can happen to me and this is very serious matter and rare incident especially that the car is only 4 1/2 yrs old and with only 35,000 miles on it. The car could have killed my family if we were driving it on the freeday going over 60-70 miles per hour. This should not be taken lightly due to high risk of automobile safety issue and full investigation is mandatory to find out exactly whether there was any mechanical defects from Lexus when it was manufactured.
