DOS1

Checked again - refitted the concertina like side panel and poked about in the rear of the window opening - something clicked - now back to normal - job done - I hope.

It's a recent problem - 1 week.  No problems with Battery .  I did notice that the small concertina like fitting had come loose but clicked back into position ok. I will look more closely . The roof opening - closing and immediately opening again could be a safety reflex so it doesnt trap little fingers  ??

RX 350 SE-L    2008

Sunroof not opening.    Also  -   tilting roof opens ok - then - when I push button to close  -  it closes and opens immediately  -  looking for some obstruction - seems clear.  To close I have to 'blip' the button until closed.   ? ? ?

As Brian said above, hydraulic tappets can lose their oil and is fairly normalish for older engines. I'm not sure if anything can be done about it or not.

Any more info? Front? Back? Engine? Can you record it so that we can hear it?

Thnx    -  350 petrol - The rattle is from the top of the engine for 2 seconds on start up - if I restart it is quiet (as it is oiled.  ?  )

Looks like the oil has drained down while stopped - ?  'Dry'  when started until oil has pumped up.  But is this normal  ?  Cheers

Hi Brendan. From experience with other vehicles ( not Lexus) if it is just a rattle coming from the top of the engine and not a heavy knocking it is likley to be one of the hydraulic cam followers priming with oil. On older engines they can loose their oil so when the engine starts they are empty hence the rattling until they fill again.

Thanks Brian - Yes it is a (dry) rattle for 2 seconds then smooth. When I restart it is quiet (oiled) This is what I suspected but is it normal ?  Thanx again

Bought RX 350 SEL not so long back - There is a short rattle on start up - is this normal  ?
