My 2000 Lexus Rx300 had an unexplained sudden unintended acceleration where the vehicle almost killed me and my son. I was driving residental backroads by my house, accelerated slightly to get up a hill and that's when it took off. The brake pedal was unresponsive, the emergency break was unresponsive, I pulled the floor mat out for good measure, nothing worked, it kept accerating at a high rate until I finally slammed it through gears to "park" to get it to a stop. I had it towed to the Lexus dealership, where the tow truck driver even told me when it started the car to get it up on the truck, after being turned off for over 12 hours, it was still red lining the engine, and even lurched forward but because the car was in park, it didn't crash into the back of the tow truck. Lexus investigated the car and did absolutely nothing. They wouldn't tell me why it happened. I demand an explanation and a replacement vehicle - one that doesn't have a history of having sua problems. I fear for my life everytime I have to drive this vehicle.

We purchased a 2000 Lexus Rx300 with a v-6 in April 2003 with 36,000 miles. We have recently found out that the engine had been rebuilt due to sludge problems at 31,000. We changed the oil every 5,000 - 7,500 miles. I have never had an oil related engine problem in 28 years of driving and have never worried about keeping oil change receipts. I only have receipts from 44,000 and 60,000 miles. The place that changed it does not have record of the two other changes at about 39,000 and 51,000. I have copies of the special adjustment letter that you refer to in your TSB's. Lexus however, is telling me since we are not the original owner that this letter and offer do not apply to us. They have offered to pay half of the repair which we have worked down to our portion $4,200. They have not pulled the heads or the oil pan and yet they know that the whole engine needs to be replaced. This tells me that they have had experience with this issue before. Our vehicle has needed an engine every 30,000 miles. I have kept engines up to over 120,000 miles without failure. If we have them fix the engine I am told that they will machine the heads at the Lexus dealer, not replace them, yet the block needs to be replaced. My investigating on the internet leads me to believe that the problem is in the heads. Just machining them and putting them back on will only ensure that I will be dealing with them in another 30,000 miles for the same problem. It seems that they have a problem with this engine that they don't want to stand behind because we are not the original owners or at least that seems to be their easiest route to take. My vehicle has been unuseable for a month now and there is no end in site.
Resolving oil sludge repair problem on used RX 300 with third party Lexus dealer--car broke down on 1200 mile road trip. Lexus paid for rental car for return trip. Repair is under warranty. My problem is the dealer we purchased the car from must have known this problem existed with these vehicles and had ample evidence of lack of oil changes in the repair history, yet did not pull the valve cover off this vehicle to determine if oil sludge problem existed. Isn't that standard practice for all used car inspections? am told by third party Lexus dealer therer is a maintenance procedure that requires this sludge inspection on all v-6 Toyota engines, yet dealer we purchased car from says this is not required.
