Power train: automatic transmissionReported July 1, 2004 · 13,000 vehicles affected
What is wrong
On certain vehicles when the accelerator is operated quickly, a small piece of metal may separate from a retaining collar located in the inner part of the automatic transmission. This small piece of metal may become caught in the parking lock mechanism.
Risk
This may cause the parking lock system to be inoperative when the transmission shift lever is placed in the park position, thereby increasing the risk of vehicle roll-away, which could result in a crash.
Remedy
Dealers will replace the transmission. Owner notification is expected to begin during july 2004. Owners should contact lexus at 1‑800‑255‑3987.

Fuel system, gasoline: delivery: fuel pumpReported June 25, 2004 · 14,259 vehicles affected

On certain passenger vehicles, the impeller inside the fuel pump may have been improperly molded due to a manufacturing error. Alcohol in some fuels may deform the impeller and cause it to come into contact with the pump housing.
Risk
This condition could increase the rotational resistance of the impeller and, in the worst case, may result in failure of the fuel pump.
Remedy
Dealers will replace the fuel pump. Owners will be notified in july, 2004. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact lexus at 1‑800‑255‑3987.

When pulling into parking space at a low speed (2 MPH) car suddenly accelerated even though accelerator pedal was not being depressed. Operator's foot was on brake pedal the entire time but car would not stop until it hit a parked vehicle. At the time the car was being turned to the right coming into the parking space. There was a high curb (~10 inches high) at the front of the parking space and a median but the car jumped over this and struck the parked on the other side of the median.

I hit a large dog while driving one night and busted my front bumper on the passenger side pertly good. Had bumper, fog lights replaced, car looks dam good. Since I am an older person, retired and drive mostly during the day, it was a while before I noticed my bright lights shine directly on the ground about 20 to 30 feet in front of the car . I have had the charleston sc lexus dealer try to eliminate the problem. They told me I would have to replace the headlight. I took it in to lexus of mobile on two occasion to try and correct the problem, all they could do was try to adjust the the bright light, but the bright lights still shines directly 20 to 30 feet on the ground, but was unable to, this has cause a larger illumination problem for my eyes while driving @ night., which I try to avoid doing at night. I love this ls 430, but need a solution to this issue. Please help

The most recent occurrence was yesterday. Has happened at least 5 other times, have owned the car for 2 years. The car will not start if the steering wheel is not exactly level, tires straight. I have to turn the wheel over and over and over to try to move it an inch so it will start. This time took about 10 minutes of doing the same thing over and over, and it miraculously started. Have no idea why it does this and when it will happen again. Most irritating and dangerous if I am alone away from home.
