My car, made by toyota, has all the same problems, faulty parts, as the cars that were recalled for sudden acceleration. I have had the sudden acceleration problem happen twice and I am currently unable to drive the car because of a faulty resistor that controls the fuel feed tot the fuel pump keeps causing the car to act like it is running out of gas. Very dangerous. Lexus has refused to fix it even though I am willing to pay. They want nothing to do with cars with the same parts as sudden acceleration.

In approximately 1995, I experienced the "sudden acceleration" problem twice with my lexus ls. At the time, no one had ever heard of it and the dealer said he could not reproduce it and could do nothing. After that I was more careful with the floor mats and thought I had solved the problem. For the last 7 to 8 years, the car suddenly slows and stalls. I have repeatedly complained to new country lexus but they just say that they cannot reproduce the problem and don't know what it is. In june, it happened again and I had to be towed by aaa. At this time I researched "lexus ls stalling problem" and got hundreds of hits. One lexus site perfectly explained the problem, how to reproduce it and how to fix it. The posting on the lexus site was dated 2005, ten years ago. The tow truck driver reproduced the problem within an hour but new country lexus would not sell him the required resistor to fix it. I took the car to new country lexus, just north of albany ny, and they have had it since june. They keep saying that they cannot reproduce the problem. They keep telling me that they cannot reproduce the problem but I keep giving them the print-out from the lexus site and the bill from the towing company explaining exactly how to reproduce and fix the problem. Finally yesterday joe moran said that he could fix it but "as soon as anyone brings up anything to do with sudden acceleration" I am told to stop and do nothing." he said "it is not in the best interest of the company to fix it." they clearly seemed to be telling me that this resistor (or sensor) is part of the rapid acceleration problem with toyota vehicles and, although my vehicle is not on the list of vehicles indicated for a "special protocol," this particular part is traced to the rapid acceleration and they want nothing to do with it.

Accelerator pedal sticks and engine continues to accelerate. I can only stop it by pushing on the brake hard, putting it in neutral or turning off engine. Sometimes if I have room in front of my car, I can stop it by pumping the brake. This has occurred several times. I cannot tell what causes it. Definitely not floor mat.

I have a 1990 lexus ls 400 and I have had to change my alternator and power steering pump 3 times due to the power steering pump having a leak and there are millions having the same problem and it cost a lot of money I think lexus should have recalled their pumps to correct this problem please help me this is becoming ridiculous. Every year I have to change my pump due to this problem they cost 600 dollars just the part someone should take some kind of notice to this major problem.
