I've searched through several Lexus forums and haven't been able to find a close-enough situation so I'm posting this one here. I've got a pretty significant rubbing sound that occurs only when making soft or sharp left hand turns. Most noticeably, when turning out of the driveway, in parking lots - slow speed turns. Noise doesn't happen at faster speeds. I've recently had the timing belt, water pump and accessory belts replaced and before that, no sound. It's not the tires rubbing on the inner fender. The mechanic seems to think that the power steering belt might be getting pushed into a cover very close to the belt. Any ideas or suggestions from anyone having had a similar problem would be greatly appreciated. 2004 RX330 - 150K miles.

I have a 2004 RX330 that when using the remote to lock the car - beeps five times. Didn't use to do this. Along with this issue is that the drivers side door lock doesn't disengage when either unlocking the door lock or when turning the ignition off to get out of the car. This only seems to be an problem when inside the car. Any ideas n either of these issues? Thanks.
