2020 Lexus IS Suspension Problems

Front Suspension (shock Absorber) uneven wear and bouncy, some vibration on the steering wheel at about 30k miles, on highway exit round about circle, the vehicle swerves left or right. very unsafe. long story short, drop it off at the dealership Lexus of Pembroke Pines FL, they said the issue was my tires and it needed to be replace, I rotated the tires rear tires went to the front and front to the back, no vibration, noise went away while driving, how ever about 10k miles later the uneven wear bouncing and noise came back while driving, Disappointed how the Lexus of Pembroke Pines handle my concern, i took my vehicle to Germain Lexus of Naples FL, I explained the problem with the suspension and they charged me to diagnosed the problem, charged me for an alignment, that adjustments were the same, before and after and told me, I needed new tires and it will cost me $1600 and my the issue will go away, Disappointed with that experience, i took the vehicle to the local shop and i was told that the Shock Absorber was the problem and it will only get worst unless i replace the shocks. Disappointed with how 2 dealerships give excuses not to replace or fix the problem while under warranty but expect the customer to spend money not to fix the problem is ridiculous, and in the end, the vehicle still unsafe while driving. front struts need a recall. Someone will loose control and crash due to the front shocks.
