Does anyone have the excessive noise and vibration in the hybrid that people complain about in the Lexus RX 350? Was considering purchasing the rx350 but after reading about the vibration and noise problem, I am hesitant to take the risk. Does the hybrid have the same problems?

 

no vibration, and no noise , the rx450 is butter smooth. Zero regrets, and when if get a rx350 loaner, I can't wait to get my 450 back,
the complaint some might have about the 450 if they are being picky, is the engine noise that remains constant when accelerating, because of the cvt it holds an rpm, and does not shift. so it could hold 2500, 3k rpm or more until you reach the desired speed, if that makes sense.
the toyota cvt is bulletproof and not the bad cvt that uses a belt or chain connected to a pair of variable pulleys, so don't get concerned or worried. eCVT uses electric motor/ generators to control the speeds of planetary gearset components. This allows the eCVT to continuously change the gear ratio, keeping the engine’s rpm in the sweet spot.

worth a test drive to compare them, it was an extremely easy decision for me. I did not pay too much attention to mileage, or split hairs on when the return on gas would brake even. The 450 is so smooth, the experience driving was worth the upcharge for us, The adaptive cruise control is super smooth as well with the cvt.
hope this helps, and hope your search goes well.

 

JSracer my feelings also towards the RX450h very happy with the decision.

 

Thank you for your response.....feeling much better about looking at this car. I will test drive it.

 

April 2021 Consumer Reports Auto Edition rates the RX450h very high in their ratings.

 

+1 for the 450h. I had a 2006 RX400h for ~11+ years and absolutely loved it. My new-to-me 2019 RX450h is a whole new level of smooth, quiet driving.

 

I have an vibration issue on my new RX 450h F Sport (2021). I've tried to replace wheels and tires, also visited a several tire services with request for tire balancing - the vibration is still there (80 mhp / 130 kmh). Dealer says: Yes, there is a slight vibration, this is normal :-(
I'm not happy with the driving comfort on the highway with my new RX450h (2021).

p.s.: I had got a previous gen. RX 450h (2011y) - no issues, I really liked the car.

 

I had the vibration issue on the original tires and the new Weather Ready tires. I took it back to Discount Tires and they told me that Lexus products are famous for balancing issues, but they rebalanced them and there are no vibration issuses at any speed up to 100. The car is rock solid. I also have a Rav hybrid and would not have anything but a hybrid from Toyota. Both the 450h and the Rav have the ECVT, which is far superior to a regular automatic.

 

I'm sure you've made your decision by now but I just wanted to chime in and say that I recently purchased a 2022 RX 450h and it is without a doubt the smoothest, quietest, most elegant ride I've ever experienced in a car. Granted I have only had the car for about a month. But I have made two 700 mile round trips to visit my mother in that time. One thing I have to watch out for is how easily my speed can climb. I've decided to always use cruise control. And with adaptive cruise control that's effortless on the interstate.

 

No vibration or noise here either in my 2022 450hL. Very quiet ride, love it!

 

I recently had that issue going on a 100 mile trip. It sputters randomly at 60 mph only when I accelerate. Thinking it could be the inverter or the cvt? Other than that it’s a very smooth ride.

 

Would not be the CVT.

 

Could it be engine mounts or cv axles? It only happens under load.
