Hi from a newbie. This site is great and I hope there are some technical members that might be able to help.
On my 54 reg RX300 SE, when the tailgate is closed with the remote button it makes a clunking noise and often opens up again.
The noise could be cogs slipping, 3-4 times. It seems like the safety feature is kicking in, making the tailgate go in to reverse to avoid crushing something but I'm no expert.
Starting from fully open, the clicks occur between 5% and 50% of the travel. If it's get's past 50%, it usually means it will complete closing successfully. The final latching action works fine. Opening and closing manually I don't feel any excessive resistance or hear any strange noises.
It was just in for a service with Lexus and they told me they'd fixed it. What a load of BOTTOM WASTE! I'd apprecaite some ammunition in terms understanding the mechanics involved and ideas on what the problem might be.
Cheers
