RX450h does not start
Hi guys. I need help with my lexus rx 450 h. It didn't start. When you press START button, nothing happens, just coming up ignition, but not coming word On clock READY. The car is after small accident, nothing serious happened just damaged engine boot but they stripped all front car parts eg. bumper wing ect. Maybe this has an effect to the car and why it is not starting or not? A computer says 'check hybrid system' I need your help maybe you have any ideas? Thanks

When a hybrid is involved in an accident, there are "g" sensors that will automatically trigger the disconnection of the hybrid battery from the rest of the vehicle. It's a safety measure to prevent electrocution should the vehicle's structure be compromised in some way. If this is what happened to your vehicle, it will need to go to the dealer where they will reset the system (reconnect the battery).

easy to tackle the problem. Do you get green ready indicator on the dash? Tried to jump start just in case your 12V battery is low in charge. I think dealers have special diagnostic
tool to TS hybrid system. I also drive '15 RX450h. I hope it works OK when weather here gets COLD(like -30C)

"Do you get green ready indicator on the dash?" No we don't, that is the problem that we are getting. but is this the problem because all of the front part of the car is disconnected like bumper, wings, headlights and fog lights? It always says on the dash 'check hybrid system' is that why?? They told us that the car was startable but when we got it, it didn't start.

Often, but not necessarily. Air bags will deploy according to direction of impact, no value in having $10,000 worth of airbags deploy for a small rear end collision, but it may be enough to trigger the battery disconnect.
In any case, this is the formal description:
I'm leaning towards this because I don't think a simple low voltage condition in the 12 volt battery would trigger the "Check Hybrid System" warning. Low voltage in the Hybrid battery would, but that's going to require a Lexus dealer visit as well.
In any case, this is the formal description:

If the emergency shut off system activates, your vehicle will not restart. To restart the hybrid system, contact your Lexus dealer.

Is the vehicle still at the repair center, or have they completed the repairs and returned the vehicle to you, and you are just now getting into the no-start scenario?
A more detailed timeline might help us help you with more detail.

I am honestly confused as to what is going on with your car. From what you said, your car is still at the repair shop. That leads me to a couple more questions as I try to mentally sort out what's going on.
1) Is the current repair shop the same one which did the initial repairs after the accident?
2) Are the repairs which are in progress still part of the initial repair following the accident, or is this a follow-up repair effort where they are trying to fix a No Start condition which took place after receiving the vehicle from the initial repair effort?
I personally think we simply do not have enough details about your situation to be able to offer any insights at this point. Maybe I'm the only one who is confused, though.
