Default Front end again?

Well, I only put on about 2 k miles since Lexus replaced all of the control arms under warranty. Now again I feel the same symptoms.
Some rattle when going over bad bumps on the right side.
And when driving on the hghway and tapping brakes, I get a thud. A thud I am familiar with when the Strut bar bushings are bad or going. Its not too bad, but I would not expect a brand new front end to feel like that.

Im due for an oil change in a few weeks. Again I'll have to leave the car for days and drive a loaner.

I'm starting to get that too. I'll be looking into it. If you find anything out about this particular symptom, let us know.

Maybe your original source of the problem wasn't necessarily the control arms.
Also another thing to consider is that most control arms need to be under tension when being tightened down and it is possible that one of the bolts has walked and it's a simple fix.
It is not uncommon for lazy mechanics to use an impact gun on these bolts without any regard to using a torque wrench.

I dropped off the car to get the front end looked at today. Let's see what they find this time. And I'm not paying for alignment if they do replace anything since their work should be under warranty .
They also goons do the fuel leak recall.
And change oil.

I got a es300 hybrid as a loaner. Excited to use it over weekend to see what sort of mpg it gets

this could be a brake actuator issue, no?

Could also be that something in the suspension was not torqued down properly and worked itself loose. This seems more plausible then the actuator or needing new bushes.

Well I got a call back saying there is nothing wrong with my front end . They offered to take a technician for a ride.
I'll have the car back Monday

when I had my 2010 tis is the same thing that happened. it was always either the control arms / struts. The tech was in my car so much we actually went for coffee once. I would always go to the same road where the noise was the worst and he would hear it every time.

So after getting the car back. The strut bar bushings are surely bad or the bolts are lose, not only can I feel the wheels moving I can see them . In drive and reverse.
I have a long trip this weekend and I don't have a car that ready for it.
They changed all the control arms only 2 k miles ago.

To say I am angry is puting it lightly.
Doubt I'll be able to get a loaner on such short notice, but I'll try come tomorrow morning .
I hate not having my car in tip top shape.

Why not try a different dealer. You're in a large metro area, so there should be no shortage of dealers around.

One thing I would say to check yourself is to make sure your brakes are not making any noises. Reason I say this is I was just at a dealer a week ago complaining about all kinds of crazy rattling going on when I go over bumps. Turns out my pads are the culprit.

Lexus of queens is on the way to work which makes it convenient .
Next option is Lexus of Larchmont,I heard good things about them.

I looked under the car and couldn't find anything wrong visually . I just don't see how the tech drove the car for 5 miles and couldn't see or feel what I'm talking about.
I'm also wondering if the ebc system is just doing its job too well because I can not feel the front end jerk at low speeds .
Front left caliper does make clicking noise when applying brakes . The actuator was flushed before I got the car so I'm not sure if that plays a role.
Brakes are new, front and back. All work done at Lexus .

Anyone who had the strut bars go bad on their Lexus would know exactly what I'm dealing with.
Dealer changed all control arms 2 month ago and all was well for a little while. I'm not sure if any of them could go bad so fast.
I'm frustrated because I have to waste more time and I hate wasting time.
