SC 430

  • miles


The consumer had problems with 2003 Lexus SC430. ***** when the driver applied the brakes the vehicle pulled to the left. The consumer feels that the problem was with either the brakes or steering. The dealer suggested replacing the tires but offered no information on where to purchase them.

SC 430

  • Automatic transmission
  • 1,000 miles
The car failed to start six times in the first five months. It seems they have found the cause of that problem. However, the car continues to make clunking noise whenever it goes over a bump. Lexus tells me that is normal. I say it sounds like a 1973 Dodge I owned 30 years ago. The car also pulls to the right at low speeds. Again I'm told this is normal and is a result of the run flat tires. If so, they should use other tires. Parking brake light continues to come on intermittently. I have requested that this car be replaced repeatedly. Lexus has refused.

SC 430 8-cyl

  • Automatic transmission
  • 300 miles
The car veers violently to the left or to the right when braking on a road that is not completely smooth. Depending upon the unevenness in the road, the car will jerk the steering wheel violently either way. We have had the car actually change lanes when braking. Lexus says that this is normal action for this car. If so, there are a lot of people in danger who are driving this model car. This has happened since the car was new. It now has about 3300 miles on it.
