1 Loud Engine Noise problem of the 2000 Lexus RX300

Failure Date: 02/10/2014

After first having to replace my transmission at 75,000 miles. It seems I will have to pay to do it again at 186,000. The problem started out with the vehicle having trouble climbing a hill. I changed the transmission oil and two weeks later the vehicle move about three feet from a parking stall made a loud noise jerked to a stop and would not move. I was able to put it into drive and repark the car. It will not reverse and had to be towed to a mechanic.

2 Loud Engine Noise problem of the 1999 Lexus RX300

Failure Date: 12/11/2008

I have experienced several problems with my 1999 Lexus Rx300. I have notice via the internet that these are wide spread problems but no recalls have been occurring. These are the incidences that I have problems with: * debris can get into the idle air control valve that allows air into the engine causing the engine to have a low idle speed, or stall when it is cold. (this occurred in the past, perhaps 2004. Lexus eventually replaced my engine in 2005. ) * sludge can build up in the engine. I routinely have to have the sludge cleaned out to avoid engine problems. * the check engine light comes on because the mass air flow sensor sends incorrect information to the engines computer. This can cause a loss of power on acceleration. (this started occurring on December 11, 2008. ) * the check engine light comes on because a component of the oxygen sensor stops working, and the car is unable to determine the proper ratio of air to fuel for the engine. (this has occurred in the past, perhaps 2005. We had to pay for new air flow sensors. ) * light bulbs frequently burn out in the taillights. * the front suspension makes very loud noises when going over bumps or rough roads. The support bushing for the suspension needs to be replaced. (this began happening in December 2007. Lexus told us we need new struts. ) * a throbbing wind noise from the moonroof. One cannot have the moonroof open at the same time as the windows or ones ear drums experience severe pain. (this has existed from purchase. ) I believe the 1999 Lexus RX 300 might very well be a good candidate for the lemon laws, yet we're not seeing problems being addressed with recalls.
