No vibration in my car. on winter tyres! I must go to the service, because it's annoying. It appear only when I'm cruising with the constant speed 70-110kmph and engine is on 1200-1400rmps. I was thinking that it's wrong tire balancing, but if I switch to a lower virtual gear and I'm keeping the speed, it disappears immediately. I meet some guy with his Is300h on the gas station, before I switched to winter tires (and this effect was unknown for me) and when I ask "how is it driving?", he sad: "on summer tires was everything perfect, on winter... this is another car! it's like riding on the grater"... I think, that it's some engine vibration resonance not well dumped.

Hi. The sound is sometimes loud, sometimes very low, and eveen totaly gone sometimes. Usually the sound only appears above 1500 rpm, but sometimes it is present at below 1500. This should not be the case if it was the injectors. Then the sound shuld be constant. No vibration in my car. on winter tyres! Hi Kmart, I live in Poland and I have the same noise and exactly on revs range that you provided. I asked the service and I've got an info that it's sound of direct injectors. Indeed it's quite laud sound, and it takes a time to get used to it. It's probably not optimal sound isolation. Hi. The sound is sometimes loud, sometimes very low, and eveen totaly gone sometimes.

Hello, I was in Lexus service and service man was carefully hearing, hi definitely told that it's "fast clicking" injector's sound and I hear them exactly as you wrote. Best way I think, is if we'll try to record this sound and we'll exchange recordings :-). Do you hear it from the right side as I am?

Hi I live in Poland and I have my IS300h by 4 months. I found strange sound and vibration after I changed tires for a winter tires. It's happening only if engine is on low revs, 1k-1.2k, and it seems to that chassis isn't dumping engine vibration well enough. I don't know, why this effect wasn't appearing on a summer tires. Before changing tires, I met some guy with his IS300h, and he was telling me, that car is great, but when he changed tires to winter ones, the car drives completely different, that he feels like riding on a bad tarmac. I was on summer tires, so it was clear that he has got bad tires, but I have now different tires than he has, and I have the same vibration. Have you ever experienced it?
