Really sorry to hear your problem. A pal of mine with a GS300 took his car to Lexus with issues similar to yours, 12 weeks later and £2,500 lighter he got his car back. Lexus stripped it down and then could not get it to start, new Electronic key/security units etc etc had to come from Japan.

if you can find a good Indy on Lexus in your area why not try there first.

 

interesting was his the same as mine then all ok then just died?

lexus stripped mine down and checked all sorts but i was not going to give them a load of money if they were not 100% sure plus not got that amount anyway i spend it on classic cars that start lol

lexus checked all wiring all can lines ok as can talk to all ecus in the car 

tracker not as far as i gather all ecus have been removed and wiring all checked 

i normally replace ecu kits on lesser cars not a lexus

yes an ls with faults is unheard of and dealer were quite upset they couldnt fix it but 1500 to 2k just to try an ecu not knowing it would work is no good to me so ill deal with it and let them know

they had rulled out the key as it can be seen knows when its in the car or not every now and then it will switch on car would fire up then stop

im looking to get ecu kit for it on eBay as  2been broken in another country but bought from copart here which is very annoying to say the least 

nice motor would love to upgrade front end on mine and clocks etc mines 2009 rsr with 253k miles currently broken on drive lol

ive got one 2009 600 rsr in hinckley leicestershire sat on drive broken im afraid

hello all just joined and thought i would post my problem with my ls on here 

yes it seems to be rare a faulty ls i used it just before christmas went to coventry all ok came back home 5 mins later went out again but no ready light  kept trying no luck plugged it in with launch gds fault in hybrid control ecu b2799 immobiliser malfunction kept trying finally came on drove to cov then to leicester and thats where it spent christmas 

picked up by rac to dealer in coventry they had it for a week with no luck they think its the i presume smart key control behind glovebox it would sometimes start then stop 

has anybody heard of this problem car is now back at home as not paying for an ecu that they cannot say if thats the problem

ecu kit on the cards atm just need to know what parts are needed?? key / smartkey ecu / engine ecu / not sure if i need hybrid ecu if thats coded or not ?
