Hi, This is my first post and I am hoping someone on here can help me as I am struggling with this particular issue. I have a 2006 IS250 and have owned the car for 5 months.
I have an issue where the ABS/VSC/TRC lights all come on at the same time once every 2-3 weeks. This never happens upon starting the engine, only when I am in motion.
There is not a common factor for when this happens, it has happened when parking on a kerb, it has happened when moving slowly in traffic, it has happened when approaching a red traffic light.
The lights will stay on until I arrive at my destination and turn the engine off, but don't appear again for another 2-3 weeks.
I have contacted Lexus in Manchester and they have advised that they can only determine what is causing this if I bring it to them when the light is on. This is obviously a problem, as it always disappears once the engine is turned off.
Now, all of this said, it does not concern me. It drives exactly the same and the brakes perform in the same manner. My concern is with regards to its forthcoming MOT in three weeks time. The lights being on would be an MOT fail, but how can I resolve it if Lexus can't diagnose the issue???
The chances are I will take the car for its MOT and it will pass, as it never occurs upon start up, but what if it does not? I am stuck between a rock and a hard place.
Any suggestions would be welcome. Does anyone know why this might be happening? Is it likely to fail an MOT if it never happens on start up?
Thanks
