  1. Hi John - good idea but done at the wrong time - I am an electrical engineer. Vas will insulate the terminals so you put it on after you have made a good connection. Clean the battery posts and clamps as well as you can - tighten them up and then apply the Vas to keep air and moisture out. This will stop air and moisture related corrosion but not galvanic action - you will still need to make sure they stay in good condition. I could blather on about conductors and connectors (I am an engineer) - however, if your cables are not thick enough they will not conduct well (they will heat up) - same for your connectors. How big they are and what they are made of (cables and connectors) will affect their conductivity - your battery has to deliver a short high current burst when you crank the engine so they need to be fit for purpose. Always take care when working around a battery - especially with a full charge in it - make sure you don't create an inadvertent short. Bren

  2. Can you take the sensors apart and dry/clean them up? I have had zero success in 'bringing them back to life'. Once water gets in them or the crystal cracks they don't last long. Once the paint chips off I try and clean them up but a new sensor is inevitable. On the seat heaters and coolers mine work well - they will never turn your bum in to a snow ball but will make you comfortable in the summer. I get the garage to mess with filters. Bren

  3. Smearing the battery post with Vaseline before fitting the clamp will help keep it from corroding. Weird I know but that is what car electrical places did last century. John

  5. Could be a wheel bearing - especially at those speeds. I would have thought if the gearbox was bad, you'd hear it at certain RPMs rather than speeds - especially on a CVT box like yours... Check what RPMs you are at when you hear it worst, then try and replicate with different gears (using semi auto mode) at different speeds. Sent from my iPhone using Tapatalk

  6. I'd have a good trawl of the forum too - great advice and thought provoking posts! e.g., http://www.lexusownersclub.co.uk/forum/topic/100779-advice-on-buying-buying-my-first-rx-300350/?hl=advice

  7. Sounds like the switch in the lamp housing may have slight corrosion on the metal that is pushed in to make contact when you slide the plastic switch over to 'door' mode. Try taking it apart (as if you were swapping the bulb) and giving it a clean, the finish on the metal might be dull (oxidised) so a buff should shine it up to make a better contact. If it's not this simple fix, then could be a loose wire on the plug. Good call Steve re: door switch, I've had this problem on the drivers door which stopped the auto-lights turning off when leaving the car! It was a devil to take apart and clean but did the trick! No need to buy a new one, just 15mins, a screwdriver, pliers and cotton buds... Sent from my iPhone using Tapatalk

  8. ..... I've never driven a car with so much, well so much of everything that's the very very best and with which I have EMPATHY too ...... 15 years now with Ls400s and having been driving since I was 17 ? ( I think in those days , 1967 ) and having driven all sorts of marques from RR and Bentleys, huge Mercedes, Aston Martin, big old Rovers, several classic cars ( classic then, let alone they would be now ) and everything down to old fashioned minis, tiny Fiats and everything in between ......... there really is nothing like my Ls400 ......... and even with the money available to " upgrade " to anything else I wanted ......... I just know I would be disappointed in any replacement. Malc

  9. Thanks spacewagon, there's just something about the 400 which was lost on the 430 and 460....I was so disappointed with the 460, the drive and feel was not what I'd hoped for. I knew when I first drove one but still bought it anyway, I thought it was "me" but after driving it for about 6 months I moved it on. I think the feel of the 460 leant more towards the euroboxes and lost the wow of the 400 which first got me in to the Lexus brand. The mk4 with DHP for me is the ultimate, I've had many cars over the years, some really expensive ones, yet nothing comes close to a 400.

  10. Hello and welcome to the LOC. I think earlier models like my 1994 LS400 had physical door light switches and from what I can see the RX400h has the same. Look along the door frame at the rear of the opening for the item shown, this is the door switch,check and see if it pushes in with your finger,if it does then carefully peel back the rubber cover to expose the fixing screw (if fitted),remove this and carefully withdraw the switch ( be carefull not to lose the wire down the door frame). Check the condition of the switch. If you remove the wire to the switch ( don't lose it as above) and touch the connector to ground (the screw hole) the light should come on indicating it is the switch at fault.

  11. I too had a noisy whining sound from the front of the car----solved it by getting the mother in law to sit in the back.

  12. Mechanics are like forum posts: some are good and some are rubbish; some forum posts are opinions and some are facts and there is everything in between. You need to look at the information you have available and make a decision based on facts and experience but make sure the experience fits the facts. Also try and understand why the other person said or wrote what they did - I have to do this for a living. I am an engineering consultant not a psychiatrist :) Look at the recent posts on here about engine oil. There are some basic and simple technical facts to follow and for a good result follow the manual - that did not stop an 'interesting' discussion here. Breaks are a great topic - I swear by Green Stuff pads and EBC disks that in my experience work really well and last well on my car (430). The mechanics who maintain my car said I was wasting money - I won the argument because I was paying. I had some break problems that were resolved when I replaced a caliper. The car was not stopping as well as it should but was OK. When the car was serviced no faults found and the pads were OK. At pad replacement time we found out why the brakes were a little soft: a stuck piston. I replaced caliper and the brakes frightened me to death for a day :) Red faced mechanics but no harm done. The lesson here is check your calipers are in good order. Always bear in mind professionals or trades men hate self diagnosis by amateurs - try going to your GP, with a load of internet prints outs and tell him you know what medical condition you have :) and everybody knows the 430 is better than the 400 - that's a fact not an opinion :) Bren

  13. Hello Alfred and welcome to the LOC. As Ambermarine suggests try a new battery 1st, I take it you have the key with the single button on the side. If you have a spare key try that to see if it works correctly.

  14. Alfred Try putting a new battery in the key fob if you have a new battery in the fob already the security ecu could be malfunctioning and that will be a serious problem because if you have to replace the ecu you will need to have the keys and new ecu coded and that can only be done by Lexus .Weather they will attempt to work on your car is another issue as they may not be able to get the parts that are needed.
