Hi guys, When i am driving my RX 400h, at motorway speed, there is humming and vibration. It starts after 50 mph. That noise and vibration go when i decrease my speed to 40 mph and it won't come back even if i accelerate. next journeys it happened again. It started with just a tiny humming and now the humming noise increased and the vibration is added. when i brake, there is no pullover or any other problem. i am suspicious about my front tires because they are cheap :)) does tyers do that or does anybody have any idea about the problem, please?

I see. No worries. I am quite new in the UK and still improving my English 😏 i will put a hair in that crack and make it hairy 🤣

Hi guys, Itheo was right, there is a hairy crack and after your comments, i realised that there is a chronic problem. i am still using adding 1 lt coolant every month. i am thinking of replacing it with starline radiator which is cheap. do you have any recommendations or experience? Thank you.

Hello guys! My coolant is leaking from tape. Do you know how i repair it? Ex-owner used that and i renewed the tape but when i push the car leaking again.
