  1. The unavoidable physics of wide low profile tyres. Unless you want the turning circle of an oil tanker!
  2. I'm assuming (dangerous I know...) your RX hybrid is the same as my RC in that the car, once Ready and driving, everything operates from the traction battery. The 12v only operates the entry/locking system and powers up the computers for the hybrid start. Again, guessing but the alarm back-up battery would be attached to (part of) the alarm module? Just throwing suggestions out there ...
  3. Alarm backup battery discharged? Car's 12v battery low charge?
  4. Any reason you're not contemplating Lexus pads?
  5. You don't say what year your NX is but the 2015 handbook shows the auto-wiper on is the first position down on the wiper stalk It is labelled on the stalk, next to the sensitivity thumb wheel.
  6. "DRS Series: 3-20 mm Thick: DRS Series wheel spacers fit between the wheel and hub, and require exchanging the existing wheel studs for longer ones (studs are included)." https://www.performancealloys.com/spacer-details.aspx?ID=2308
  7. I've never found any detrimental effect on mpg by running the a/c, on any car I've had.
  8. Being a 'battery' car my a/c runs off the traction battery, so the engine shuts off at the lights but I still get a/c
  9. Mine defrosts very well but is less successful at demisting ..
  10. Recommend leaving the a/c on permanently. Not only does it rapidly demist the windows and dehumidify incoming air it will also dry out the cabin generally. Most a/c system benefit from being run continuously as it maintains the system seals as the refrigerant contains lubricants. I never switch mine off, ever. done the same in every car I've owned that's had a/c.
  11. Probably posted up before but worth a browse for us newer owners curious how our tech works.. Nothing too deep just some nice flashy images http://drivers.lexus.com/lexusdrivers/videos/how-it-works
  12. Most of the movement is in the tyre itself. Flexing then snapping back, which what one tends to hear and feel. This video of the same thing on a Merc GLC, You can see the tyre deform. Thankfully my experience with the RC is no way as bad,,,
  13. No, what we are realising from this thread is that with the very low profile tyres and colder weather, we are noticing this 'characteristic' (as Mercedes Benz describe it ) at extreme lock. There is no 'poor' design with regard to Lexus or MB come to that.
  14. The top few lines on mine seem to be on a separate section, I believe they are antennae for the radio. Certainly was the case on my previous cars...
  15. As wheels get bigger and tyres get thinner this will be more common. Does the car on 16" wheels still do it?
  16. Aren't these tyres designed for SUV and 4x4 vehicles? One shouldn't fit tyres of lower speed rating than originally specified for the car. Exception is for winter tyres. Check with the recommended fitments shown in your handbook. Personally I would be looking for a different tyre with the correct rating.
  17. A tracker won't stop your car from being stolen and can easily be disabled unless one has purchased the very top spec unit. It may help in it's recovery. The question I would ask myself is, would i want the car back should it be stolen? What damage may have been inflicted? Some insurers may require a tracker be fitted. Some lease companies may also require it to be fitted. Personally I would not bother unless forced to.
  18. The TPWS uses existing sensors (ABS) to compare wheel rotational speeds, so no extra hardware cost, just a bit of coding. The TPMS does, as you point out, use relatively expensive sensors. These typically last 5yrs and as the vast majority of new cars are lease/fleet buys, this won't be an issue for them. Second hand buyers will have to face the replacement costs though it is feasible to replace the batteries at a fraction of the cost. A member here has done just that.
  19. Very common on Mercedes 4Matic models and is due to IIRC the Akerman(?) angle. MB's response is to offer winter tyres. I've noticed a slight judder/knock on extreme lock but only on cold tyres when turning 'enthusiastically' in my RC. Not really an issue
  20. One of the easiest regular checks to do but probably the one most often ignored. Introduction of run-flats may be a big factor for having TPMS. EU legislation now requires all new cars to have some form of warning system. Increased fuel consumption ( and therefore emissions) probably the greater prompt though
