Engine Shutter Rx400h

[phil400h]

Has anyone had this problem? mainly happens at stop lights when starting up. There is a slight shutter (as the dealer calls it, says it is normal in all RX400h Hybrids) when the ICE starts up when you accelerate from a traffic light or sometimes hear it it stop & go traffic when going from battery operation to the ICE start.

I also hear it in the morning when the car is cold & start backing out of the driveway, only it is louder in the morning.

Did stop buy the dealer last Saturday & took their demo for a ride, I noticed it in the demo also. Seems to less of a problem after the car is warmed up, but you can still feel it. Is this just something you have to get used to.

Thank You, Phil

In the 1000 miles over three weeks, I have had the same experience, I think it is just getting used to the car.

Yes. this is normal but is so slight that I'm not concerned at all. The brief electric motor roar is much more noticable, IMO. Luckily, it doesn't last long and happens only during agressive gas pedal pushing.

Thats just how hybrids are, you'll get used to it. Its odd.

It does kind of feel like the car stalls at each red light. After a while, you get used to it.

I have 4000 miles, and it appears to be normal operation of the hybrid system to warm the engine up during starts and shutting down to save gas at stoplights.

Funny you ask that, I thought my garage door was falling apart, but it was my lexus makin' that shutter, heh
