First of all, change the Lexus Dealership who is doing your rigid maintenance because they are ripping you off and not doing the work or careless on the way out of your engine compartment.
At 95k, you should have changed out your timing belt, replace all the sparkplugs, cleaned out the throttle body, cleaned the MAF sensors, replace the O2 sensors, inspected and replace the fuel rails, and the spark distribution units and you should not be getting a simple problem as this.
All this said, open you hood and look for a vacuum hose that is disconnected.  Most of the hoses which will cause this type of problem is located around the air filter box or connected to that side of the engine.

The engine does not start. system says check hybrid system


dealer,
its a hybrid,
or take it to any ASE cert mechanic. ask them if he does hybrids.
good luck with that... scan it, read the FSM
if not DIY or fully trained on Hybrids, and the FSM means zilch to you
then leave it alone. (high voltages are lethal)

Very frequently the eps of my i10 car out of order


EPS is dealer , fix.
if you dont believe it
then buy the FSM and read.
if cant afford that (and EPS) then login to , alldata.com
and read about it, it takes factory tools.
a Hybrid is a very complex car, and a short leash to the dealer.... RTM !.
good luck with that and 10x that on old ones.

Getting ride of toyota hybrid system


Just trade the car for one you like. First of all, I don't know anything about the hybrid system, but I think you would be facing a modifier's nightmare. Just think, all the wiring, all the computers on the car, are designed for this hybrid. If you put in a gas engine (one from a '98 Camry, I would think), you would need that engine harness, that computer, likely several modifications to electrical connectors, you may need a different fuel pump,different relays and switches...to me, the necessary modifications seem endless, and pointless...just trade it off!
