Is it exhaust system or suspension

Need help on resolving this issues asap

My Trac On, VSC and check engine on and we tested it and this code P0355, what does this mean

It gets louder if I turn. at about 50 I don't hear it. No vibration. No Clicking. Noise stops when I stop rolling. Looking for cost estimate of what a shop might need for repair.

There were no error codes displayed. Freon was added by a mechanic, but the problem continued. Reasonable or expensive fix?

Today a chunk of my dashboard fell onto the floor.
There are three other elongated cracks passenger side near
air vent. I am mortified and disappointed in lexus. I waited
a really long time to afford this car. Never had this happen
in 45 years of driving cars.

What damage can be done to the engine etc as I have to drive 18 miles to get it to the garage/home. I keep stopping until it cools but I am concerned about the engine and more damage. The temperature gauge at first was going from cold to hot and back down to cold, as if the needle was broken but now the engine has cooled down the temp needle looks to be working fine although it keeps going in the red area and then I stop again.

Thank you

it stinks like sewer. Pulled up carpet floor insulation and carpet were soaked.

I have 91,000 miles What might be the problem

The brake pad and disc were just changed. but the next day, after a while the car vibrated and showed check engine and VSC lights. the lights are yet to go off completely as it has been reset with the scanner. also, the car still vibrates occasionally.

Do I need to take care of it right away? Can I wait for a couple of days to take care of it? It's Saturday night.

Lexus Dealer retail price is $180 for each lift but there other lifts available on the internet for considerably less money. However, I have no way of knowing the difference in quality between the Lexus lift as compared to other aftermarket lifts. The lifts on the Lexus look pretty ordinary and I have replaced lifts on minivans over the years and they didn't look much different that the ones on the Lexus. Any comments?

Two of the five bolts snapped off from the hub and I need to replace them. Will I be able to do it myself?
