No NAV could be the DVD system in the boot... or...?
Heater controls - could be anything?
The SE-L will have air suspension. Great if it works but £££ to fix.
Unless it's for minimum £ i'd walk away - what else might be wrong, yet to be discovered?
Any link for the car?
Sound advice from John and Barry.
I have had excellent value from my Lexus Warranty ( about £7,000 ).
I suspect any other warranty, Gold, Platinum, Aardvark etc., would have paid nothing?
I guess any car can or cannot have issue...
I would go for it.
Others here will have more objective advice.
Find the best genuine, honest example you can with good service history, good MOT history ( you can check online. )
Lexus online might have some, or ask your local Lexus dealer to look out for one. Maybe a part/ex?
As... Herbie, my wife has discovered.
RX 450h goes 'dead' quicker than my old RX300.
She had to call Mr.AA, who arrived and thought it was my car with the issue, as they sit next to each other...
Happened to my wife's RX yesterday - same message.
It was the car battery ( not the fobs ).
[ She called out the AA who I assume started it with a portable starter - then let it 'run' for an hour. ]
