GS 300h 2018 & GSF 2019 canbus theft risk

Duggie B · August 14

Hi all.

After waiting for any news from Lexus on the potential added security/vulnerability canbus theft issues on the GS models as per their info as to which models are at risk of theft, I yesterday sent an email to customer relations regarding the risk of the two vehicles in our family (as per topic title).

Those of us who have the said vehicles please see response received back from Lexus CR.

So..........whilst she apologies for any disappointment, is this actually good news? i.e. the GSF is NOT at risk of theft via the CANbus?

Or am I misunderstanding this?

They are incorrect. I know of two, one on this forum that has been stolen via Canbus.

I have replied to her showing the official Lexus bulletin that clearly states GS & GS F model years at risk.

I will update as soon as I get a response.

To my knowledge all GS Fs are vulnerable. The headlight ECU and Certification ECU (door lock control) are on the same CAN bus (bus 2) which allows the attacker to disable the alarm/unlock the door via the headlight wiring.

I would just leave the door open if it’s so easy to steal.

No point closing the car, less potential damage.

I suggest to install some decent tracker to at least find it if theft happens.

All above is not a joke.

Today I received a phone call from customer relations (pleasant lady) who was extremely apologetic for having given me the wrong information regarding GS/ GS F vehicles.

She had, upon reading my reply with a screen shot of the official Lexus list showing vehicles at risk, gone back to the Technical Team who checked again (apparently due to both cars having cherished plates they checked against vin numbers this time) and have agreed that the GS F cars are at risk but the hybrids are not due to being built on the different global architecture.

The good news for me because of this being wrongly informed, as a good will gesture they will fit a tracker and geo fence to the 300h as well as the F.

So to clarify.

GS F is sanctioned for security upgrade.

Hybrids are not sanctioned (except for mine).

Apparently dealers are aware of the models concerned and GS F owners should book in with their preferred dealer to get the ball rolling for fitment of the security enhancements.

Perhaps this thread, or part of it, should be put as part of the sticky on this subject at the top of the GS forum?

Interesting. I’ll call Bristol Lexus tomorrow to see if I can make the booking.

Would appreciate some feed back on how it all goes🤞

I haven't found a window of time to get mine booked in as yet, mad busy with work atm.

Typical I get the positive response from Lexus only to be scuppered on the work front

Did everything go ok with the work on your car?

Still waiting to get mine in.

F.A. · August 28

Yes all went well. No issues to report.

From what I know from the RX and LC forums if your GSF is at risk you should be offered a free cat S7 tracker and 3 year contract, plus an OBD geofence device. I’d also add an immobiliser PLUS stickers to warn the thief away as all these high tech solutions are invisible.
