Gas Pedal and steering wheel Vibration when RPM around 2200
I Just leased UX250h at the end of last month, and current ODO is around 1200 miles.
I just realized that the gas pedal and steering wheel will vibrate while the engine speed is around 2200RPM. No problem when less than 2000RPM or more than 3000RPM.
No mater if the vehicle is parking or not, the only thing is need to push the gas pedal to force the engine to around 2200RPM.
It doesn't have this issue when I first drove this vehicle.
I just send my vehicle to dealership service center today, and they need more time to compare to another brand new UX250h which is not in service center right now. They promised that they will give me a call tomorrow.
Got a leaner vehicle which is RX350, and carefully checked the engine sound and vibration when I drove home. This RX350 shows similar engine sound while engine is around 2200RPM, but NO gas pedal and steering wheel vibration at all.
The dealer and I compared with another UX250h F sport, same behavior when engine is around 2200RPM.
Because of that, they told me that they can do nothing about it. But he recommended that I can complain to Lexus to see if they are willing to investigate it.
Just park the car in parking lot, then push the gas pedal to make engine speed over 2200RPM. Most noticeable vibration happened at 2400RPM per my today's test.
Change to sport mode, then you can see the engine speed.
I checked RX350 which is V6, it has similar issue when engine speed is around 3500RPM.
The UX is probably using the same engine mount as the CH-R and the Corolla. There are additional braces on the UX that could possibly transmit engine vibration into the cabin. As far as the RX, there are more damping material that will cancel out engine vibration. It is their bread and butter SUV.
A 4 cylinder will not rev as smoothly as a Toyota/Lexus V6 engine.
It could be a number of factors such as fuel and atmospheric conditions. To rule out the fuel, try a completely different brand and perhaps even a higher octane.
From experience with the NX, there's a vibration around 750 rpm noticeable in colder temps and winter gas. Barely an issue in summer.
Here is in California, around 20+ C at daytime.
Very quiet and smooth, barely notice the vibration under 1800 rpm except cold start.
Tried Shell Regular and Midgrade, both shows same behavior. Just changed to Premium, will see what's going on. If no different, will go back to Regular since UX only require Regular gas.
Talked with other UX250h owner in different country, they told me theirs has same behavior. Seems like by design, it has this problem.
I wouldn't say it's a problem. It's a characteristic of a 4 cylinder engine. My co-workers NX vibrates at idle. My IS200t vibrates at idle. My Mazda6 vibrates at idle. My GS300, 6 cylinder, with 160k vibrates at idle but because I had a strut bar that transmits vibration to the steering wheel.

I got zero vibration and have no issues at all like this on the UX250H F Sport. I've also read there is no benefit or advantage whatsoever using mid grade or premium fuel. This vehicle is optimal with Regular Leaded, and gets outstanding MPG, more than what Lexus publishes. I have only around 800 miles so far, maybe the vibration will happen, but so far nothing.
4-banger engines (inline 4s) are inherently prone to vibration as it is. So yes with a small 4 cylinder engine, you will get some vibration. Especially transversely mounted ones. Just the nature of the beast. It's inherent and normal. Engine mounting systems in modern cars are hydraulic and mask a lot of vibration as it is.
Ok, so I got the UX 250h two days ago and I do feel a slight vibration in the gas and brake pedal in the 2000-2500 rpm range. But none in the steering wheel. I will pay closer attention next time I drive it.
Located this UX post while perusing Clublexus forums for accelerator pedal vibration.
Residing on LS400 forum, offer these posts for your perusal which address remnant gas pedal vibrations.
I tell you this, the dealer is not going to perform any of these modifications, but application of mass loading products offer real solutions.

Any comments or input is appreciated.
Hi, was this issue ever resolved?
I purchased a 2019 F Sport and during this drive it was OK and drove like a Lexus but after purchase ( next day ) I drove on the highway and I feel that vibration you are describing.. it literally feels like if you had loud music on the car and you feel that resonance/vibration on your clothes. In my case I feel it on both my legs and floor of the car. Also my passengers also feel it.
it does not feel like a Lexury car at all, it feels like a corolla ( no offense ) with a nice interior.
this is really driving me mad as hell, currently my car is at the dealer, they are replacing the tires to see if that fix the issue but I know it wont. The loaner they gave me has same vibration when driving on the highway. Man wtf I am mad, cant believe a Lexus does this!!!!!!
