2004 Lexus LS430Engine & cooling

Sometimes, the car's RPM goes up to 4 and stays there as the car is unable to shift into the next gear. So, the car is not really accelerating at times when this happens. I have to pull over and turn off the car and start it again and sometimes it works correctly and at other times it doesn't. I've started to get check engine lights from time to time that point to solenoid issues. This makes driving this car very dangerous as this issue happens randomly.

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. Consequence summary: this condition could increase the rotational resistance of the impeller and, in the worst case, may result in failure of the fuel pump. Owner replaced original failed fuel pump with pump supplied by lexus dealer. Service manager at walcher lexus in wichita, ks indicates vehicle was manufactured in february, 2004 outside the range of the recall vehicles.Lexus technical support was contacted and referred me back to my local service manager. No one seems concerned that defective cars continued to exist outside of the range of vehicles identified in the original recall.

I own a 2006 lexus ls430, which I've had since new. It only has about 70k miles on it and has been maintained solely at lexus dealership where vehicle was purchased in raleigh nc.

No malfunction indicators appeared on the dash before or after this. My vehicle had at least 10 gallons of fuel in the tank as it indicates about...

⅝ full. I was able to restart the vehicle after stopping and the car ran fine on my way home. I am scheduling an appointment with dealership for inspection but this was scary and I'm just concerned if the same thing happened at highway speeds if it could be fatal like the gm ignition recall. My vehicle is equipped with keyless ignition so no keys were in the starter that could have switched ignition off.

Also we do not want to make expensive repairs, particularly if we are not sure it will solve the problem. Also we are very much interested in any similar problems that have been reported and their solution. *Tr
