Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #10070188, filed 2004-01, 1,000 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.”
NHTSA complaint #10049111, filed 2003-12, 300 miles“The consumer had problems with 2003 Lexus SC430. ***nar*** 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.”
NHTSA complaint #10162624, filed 2006-07“When driving on uneven pavement steering wheel jerks hard to the left and right when braking, occasionally changing to another lane. The dealer was contacted.”
