Do Not Sell My Personal Information Jump to content


Recommended Posts

Hello guys, I have had my IS300h for a little while now, about 4 months. I am so careful with parking it anywhere and am just curious as to if anyone could give me any insight on whether the IS300h cats are being stolen? If they are how much to replace one? Do they have any protection mechanism on them? Are these cars being targetted? Can i park in public places without fearing? Does anyone know where the cat is located in the IS models and if they are safe. Any responses would be much appreciated. 

Thanks.

I've not heard of any IS300h cat thefts yet. I hope I'm not tempting fate.

The catalytic converter on the IS is mounted diagonally between the engine and the bulkhead, therefore it isn't accessible by simply jacking the car up and lying underneath for a minute or two.

Yes the primary cat is on the exhaust header/downpipe in the engine bay, the same as it is for the Prius, CT200h, RX400h, RX450h etc. but it is the secondary cat that gets stolen which is under the vehicle on ALL Lexus hybrid vehicles.

The IS300h just isn't targeted as the cat isn't as valuable as older vehicles.

The secondary cat also sits slightly raised, very much near the centre of the vehicle meaning you’d need to jack it up quite high to get a reciprocating saw all the way through the pipe. In addition it is only 360mm in circumference, which is pretty small (I.e. less precious metals inside) compared to most catalytic convertors. Also, if you want to be a bit “extra”, you can use existing mounting points on the rad bulkhead and bumper reinforcement to add stainless steel mesh in front of the horns to frustrate, deter or at least slow down the cutting of the horn cables (which they do to silence the tilt alarm).

Pity there isn’t a way to connect up to the traction battery when parked up.

Made me laugh out loud this one! 🤣👍
