I have 2010 IS350,

Today as i was in power mode i have noticed for the first time a red circle in the tach gauge and the engine went close to 7000rpm(just a bit under) in the second gear. Is this dangerous for the engine and did it happen to anybody, please i am worried since the car has only 2500km. I tried it again and the car changed the gear at 6500rpm, exactly where the redline is. I have no idea how the computer alowed it to cross into red zone, not by much but for sure up to 6900rpm. Can anything happen to the engine please respond if you know

Thank you!!

It is a personal setting. You can change what RPM the car is at when it turns red. It's so you don't really have to take your eyes off the road when you want to know when to shift with the paddles. Same thing for the speed. It's the control with the left and right arrow with a button in the middle. Behind the light switch.

I know about that, but i actualy saw the needle gauge going past 6500rpm where the red zone begins, and the computer changed the gear at about 6700rpm or 6800rpm which is in red zone.

The gear should've shifted automatically to prevent the engine from going beyond the start of the red line. Looks like a computer diagnostic check is in order. & Not to worry, you're under warranty. Take it to the dealer. Noticed you are in Toronto, take it to Lexus On The Park - outstanding service

IME it will only let you hit/pass redline for a second before correcting. I am no expert but it should not cause any damage (or else it should've shifted sooner) and the car is pretty good at not letting you damage it.
