Yes, I am quite new, as in a few months new to hybrid as well, and I know that the car makes weird noises from time to time, like when you just open the driver door before your enter the car, then the artificial noise when the car is moving slowly, then the high pitch noise when the regenerative brake is working, these are all the quirks of a hybrid system. You kind of hear it more pronounced because the car is otherwise silent. I have had numerous such questions, and almost all of them got answered by previous posts in this forum, and yes all of them are normal. Yes the car is quite loud when you speed, again this is normal for a regular 4 cylinder, but is again more pronounced because it is silent otherwise. Don't worry about it. As another post mentioned just a while ago that the car noise inside is still significantly lower than BMW 1 measured with noise meter. The engine is otherwise quite sturdy.what happen was that we were on the highway during traffic and the speed was slow so i was doing EV mode for a while and had many device turn on so battery was running low, suddenly the car started to shake like crazy and i started to cut off most of the function that required power and the shaking started to go away(maybe the speed started to pick up too i don't remember cause it was while back).
for me this car always makes weird noise here and there and it confuses me time to time. i am not sold with the hybrid driving experience that Lexus said it will be, what i get is a car that makes weird noise and loud engine noise whenever i need some speed( i am not a crazy driver at age 32); only some times when i don't press gas the car rides smooth and quiet but under super slow speed during slow to zero acceleration.
worse part is that when i called my dealer, my dealer told me not to waste both of our time to send the car in cause if the engine light is not on they wouldn't be able to find any problem. lol Lexus On The Park Canada
