Rattling after engine switched off while driving slow
my 4rx 2016 450h is at service already for 4 weeks. The problem is that when I'm driving slow (cca 30 km/h), I push the car to switch the engine on (by stepping deep down on the accelerator) and then let the car switch the engine on (pulling my foot from the accelerator) I can hear 3 - 4 times rattling sound frequently after each other. This happens when the engine is cold (i. e. when I drive in the morning after I sleep). The dealer is consulting the problem with Lexus, but obviously they can not find a solution. Additionally, they found out that all of the hybrid 4RXs have the same problem, where my car is the loudest in this rattling sound.
Do you guys have any experience with this?
I am already being sad - 4 weeks without a premium car? And they gave mi 10 years old gs firstly as a replacement and now a hybrid Yaris

I already have had this car in repair for a longer time (cca 3 weeks) because of vibration in cabit (turned out that a plate was loose somewhere in the cabin).
Ok I can live with small car for a certain time when I forget people laughing at me - I suggested everyone to buy a Lexus for its reliability, now I drive a tiny Yaris

Do you have any experience how for example BMW or Audi, Mercedes would deal with this problem?
As far as your knocking sound I've never experienced something similar with my Rx450. How about you try one of the new once from their lot and see if you can replicate. From my experience when you deal with a sound or a noise first thing what dealer says is they all do it or it is normal for this car.

Your current rental might not even belong to a dealer, it might be just a regular rental from enterprise or such.
If your vehicle must be kept overnight at a Lexus dealership for a warranty covered condition that requires more than eight hours to repair, Lexus will provide you with a complimentary loaner vehicle for up to five days.
Anything above and beyond what is specified in the warranty guide is up to the individual dealer. For example, mine will provide a loaner for any service lasting longer than 2 hours.
PS I wouldn't take a Yaris because I'm not wiling to fiddle with car seats and everything else in this tiny uncomfortable car.
