What 2005 Lexus LS430 owners say
Speed control & acceleration
The consumer experienced sudden acceleration in her 2005 Lexus ls 430 while pulling into a parking lot . The consumer doesn't think the air bag inflated all the way because her noise hit the steering wheel. Her right shin smashed into the dashboard which resulted in a very large hematoma on her right shin. Smoke started coming out of the steering column and soon after flames could be seen through the heavy smoke. The fire was extinguished by the fire dept. It took 6 1/2 days for the vehicle to be repaired. The consumer request that the manufacturer reimburse her for her medical bills, rental payments, lease payments and amount paid to lawyer.

On sep 17, 2009 as I left a gas station the Lexus LS430 year 2005 accelerated and I was only able to avoid the cars in front of me was to swerve to the right and jammed of the brake with both feet. Unknowingly I ran into a telephone guy wire and the only damage was superficial ($3300.00) to the right front light and bumper. For the last few months I have been trying to figure out what could have possibly gone wrong. I notice the accelerator pedal appears to momentarily stick. Usaa fixed the auto and though I wondered what had happened I did not report the accident until now.
Air bags
I have owned car since new. All service performed by same dealer on time. All repairs done as suggested by dealer. Air bags recall performed in 2006. New brakes within 6 months. Driving to my wife"s work (airport) on same route for 38 years (37 miles from residence). I observed red light and cars stopped 100 yards ahead 1/4 mile from destination. I applied brakes several times to no avail. I told my passengers that I could not stop and applied brakes several times again. Brakes did not go to floor. It felt as though cruise control was on - it wasn't. I avoided a few cars by steering to curb and sidewalk. I observed a light post on sidewalk and had to turn into traffic hitting two cars. A motor policeman was directly behind me and said no brake lights came on. No air bags deployed and left side rear passenger's seat belts failed. Car was totaled. …
