  1. I am not sure about that starter, but the Denso starter in other Lexus models have a rotating contact in the relay mounted on starter.  They get burned.  when it starts sometime, and not other times the contact is moving to a better spot.  This relay (which is mounted on the starter) can be repaired with a Denso starter relay contact kit.  The only issue on your car is that it is buried under the intake on back of engine.  The kit cost less than $20.

  2. I am now at 249k miles on my fantastic RX400h.  One of the issues that shows at that mileage are the cooling fans on the radiator failing mechanically.  The motor shafts were actually wobbling.

    Those motors are quite expensive at $200 apiece, total of over $400 for motors.  On the other Lexus site a gentleman came up with TYC radiator cooling fan assembly that had motors that could be take off a Toyota Highlander Hybrid 2008 that fit our different shroud assembly.  I did this last night and it was a direct fit, including the plugs and harness.  Just remove assembly and take fan blades off and remove motors.  Here is the final good news, the whole Highlander assembly cost $139 at your favorite site ie Amazon or Rockauto.  The shroud from the highlander will not work in our cars as it does not have the expansion tank.  You use only the motors and our old fan blades.  Top of the morning to everyone.

  3. Well, records are important.  I bought my RX400h hybrid in 2010 with 80k miles.  It has been the best automobile I have ever owned.  We now have 248k miles and other than normal maintenance and one hybrid cooling pump failure early on it has been spectacular.  Cant help you on 450H, but I hated the joy stick on early models....

  4. So far no issues, but at this mileage the vehicle is pretty much not work much even though it is in excellent condition.  I figure drive it till it dies, if the battery goes I would consider replacing with aftermarket repairer with warranty.  No car payment is king.  Thank you for your service, I am a 8 year Navy Veteran.

  5. The plugs were due at 120k miles, But if you want to know, I have 237k miles on my original plugs, I have planned to replace them for about a year, but family things have stopped me.

    I have the plugs and the procedure sucks as you have to remove the intake manifold to get the rear plugs.  I would like the newer features of collision avoidance, etc.  As for smart key, I could take it or leave it.  funny I had to make a 300 mile emergency trip yesterday, and man I still love this car, I find it the best car I have ever  owned and I have had British cars, german cars, Hondas, Fords, Chevrolets, Toyotas, and an RX300.  The Rx400h is a beautiful, powerful, and long distance favorite.  Good luck in your quest.  Also in my state, keeping the old one going is cheaper registration, wise and not having a car payment is king.

  6. I am on four different sites, two Lexus, one Toyota, and one Ford.  Your question about causing leaks is asked in every forum, Yup could be,  but after wrenching on Cars for over 50 years I more than suspect that the leaks were there before, and the switch to synthetic just accented it.  But I will give you this one, but friend I am not here to fight, just to provide info just as you did.  But welcome to our forums, and may I suggest the Club Lexus forums also.  You will find a wealth of knowledge between these two sites on the Lexus.  We come on these forums to help people as well as get help from a data of owners that have experienced these problems and have come up with solutions.  Hope you have a great weekend.

  7. Agree totally, except on synthetic, The question of leaks has shown to not be a problem.  You can also stretch changes to 7k with no issues, and purchase at Walmart cheap.  I Fully support use of synthetic for better lubrication and its ability to reduce sludge.  Thank you for the great advice, I hope to see you share more, we all benefit from our knowledge base.

    I know about the sludge engine thing. My question is why did it take 125,000 miles to destroy the engine? If I buy another engine how can I be sure it will not happen again?? This really makes me sick, I'll have $10,500 into this 2001 RX by the time I'm done with it. I could have bought a 2008 instead.

    Time is the enemy on this engine, I first hand saw what happens to my neighbors highlander with same engine.  His wife only drove short under 3 mile trips daily, the engine never warmed up to proper operating temp, He also used non synthetic oil, when we took the engine apart there was gobs of tar like sludge throughout, the oil pan was the worst, it had blocked the oil pump strainer and caused the failure.  I personally had the RX300 (1999) and never experience this problem even after 14 years of ownership until I sold it with 189k miles.  But the key was I used synthetic and kept up the maintenance.  At the time I was using Castrol Oil German formula.  First oil change after switching even the crust came off where you add oil...I apparently has great detergent properties.  On my RX400h I used Mobil 1 and Penzoil synthetic.  I am at 235k miles. Sorry for your failure.  If you take the front valve cover off which is easy, you will know whether you have sludge or not...my neighbors car was terrible under that valve cover.  Lexus made changes later in the valve covers to help the sludge issue.  Good luck friend, sorry for your problem, We all have those terrible experiences, but remember these are mechanical beast, and they need attention.  sometimes more than other engines. 

  9. The engine could have had sludge.  Quite prevalent with that year and not using high quality oil.  Once the sludge build up no amount of good oil is going to clean it out.  Also possible because of sludge in the oil pan the pump starved and no oil was going to cam.  There is also screens on the VVTI cam solenoids that could have plugged up causing oil starvation.
