If it is engine related then have it checked out for sure because it does not sound normal to me. Regards, Quote Link to comment Share on other sites More sharing options...

Gaugster Posted August 20, 2008 Share Posted August 20, 2008 I think that is normal. I know that it won't shift into 6th even at high speeds until the car's engine temperature is above a certain level. But again, that is normal for these cars.

IS250_rookie Posted August 24, 2008 Share Posted August 24, 2008 Completely normal, get used to it, it's a Lexus. It's their way of making the acceleration slower, to save gas. They use electricity to control the response from the pedal to the engine instead of hydraulics so it's really slow and can be frustrating at times when u need acceleration. There are only two ways to solve this problem - Use the S mode and change gears manually or Turn on the PWR button. The power botton is right behind the steering wheel on the right, it's a switch right next to the traction control, once you switch it on a green light will come on. It makes the pedal more responsive but can also decrease your fuel economy if you're not careful. I usually use it around town and then switch it off when I'm on the highway and just want to maintain a certain speed. Hope that helps.

I'm starting to think that the transmission was slipping on 2nd gear, because i can feel the hesitation (hiccups) every time i accelerate into 2nd gear. Sorry, one more question guys. The curve bump that sticks out on the gas pedal side where you can rest your right leg on, it gets kind of hot at times, is that normal? Once again, thanks for the help fellas!

I don't rest my leg on that part so I don't know if it gets hot... but the only reason it would be hot is from transmission which probably isn't normal considering that there is a transmission fluid to keep it cool.

Hrmmm, then i guess I should bring it in to get it check ASAP before anything bad happens to my transmission. Also, the shifter led lights gets really hot as well, where (S, + , - ) is at, do you think it would be the transmission as well? My Appointment is next 2 week... hopefully i won't damage anything during this time. Quote Link to comment Share on other sites More sharing options...
Gaugster Posted August 25, 2008 Share Posted August 25, 2008 The bump is due to the AWD system. There is a front drive shaft that powers the front wheels and the body was shaped to make room for the extra stuff. That alone would not make it hot but it is also very close to the exhaust/catalytic converter. The cat' could be the source of the heat but I myself have not noticed it being hot. But I don't wear shorts much either. Regards, PS welcom to the club. Quote Link to comment Share on other sites More sharing options...
