Default 2007 rx350 knock noise

I just recently purchased the rx350 from a lexus dealer and I took it it home not only then did i hear a knock noise. It happens when i come to a stop and then press on the gas i hear and feel a knock. Its just one knock and then it goes away. This happens not every time but every 2 or 3 times i come to a complete stop. I was wondering if anybody had any ideas on this. thanks

If you bought a CPO (Certified Pre-Owned) Lexus, take it back to the dealer. If not, take it back anyway to get it looked at.

All the more reason to bring it back for service sooner than later. The longer you wait, the more liable you are for the problems with the vehicle.

It sounds like the symptoms you describe are repeatable and the dealer's technicians should be able to diagnose immediately and put it right for you. They will probably be interested in how a vehicle with an obvious problem got through their reconditioning process without detection.

When I bought my RX350 a few weeks ago there were a few problems on delivery and all the SAs were all over it, asking themselves who checked it out, etc. Perhaps this is the relentless pursuit of perfection you hear about at Lexus...

In all seriousness I'd recommend that you have your car checked out in the event that your problem might be safety-related.
