Lexus had a service bulletin to fix this brake squeal. You aren’t the only person dealing with this issue. Lexus revised and updated the brake pads with a different material to reduce the squeal. Not only that, but they need to properly hand torque the lug nuts to also aid in preventing the brake squeal. The dealership you went to should’ve checked the TSBs and replaced the brakes pads before releasing the vehicle back to you.

Sounds like your AC compressor is possibly locking up and causing a restriction on the drive belt (rubber smell?). Try disengaging the AC clutch. And have someone check your alternator charging output. Do you remember if your battery light indicator came on while your were driving?

Start by Cleaning your maf sensor with maf cleaner. Clean your throttle body.

I'd check the differential mount rubber bushings. Possibly worn and cracked. If anything try rotating the wheels to see if it changes the vibration.

Seems like you have a Short from power to ground. I'd start by getting a wiring diagram. Figure out what those relays are for which circuit. Then grab a volt meter and see where your short is coming from, it's possible that it's in the junction block or after the junction block. Are there any after market electronics wired into the car? Or has the car been take apart before?

Possibly the receiver is damaged internally. Is there any drink spillage?

It's not an easy job. Not only that, but make sure the starter mounts flush and bolted correctly. You need two people to remove the intake manifold.

If your a student, you shouldn't be buying a Lexus. The maintenance is going to be expensive. Why not buy a more practical vehicle that doesn't cost much to maintain. and if a vehicle is leaking and making unusual noises, please don't buy it

Warranty should cover it. Most likely the tires are uneven, they need either balancing or replacement

If I were you, I'd try getting quotes from a few other different shops before you jump on that one. $2600 does seem a little outrageous, especially 16 hrs of labor just for lower control arms

They are technically right. It even says it in the repair manual from Lexus. A portion of the lower control arm is bolted under the side engine mounts. However, there are others ways around in replacing the lower control arms without removing the engine.

If only you had a scanner to view the engine data list, to see the oil temperature readings. Could it be you have a faulty oil temp sensor? Next thing you can do is to test the sensor.

Check to see for any signs of coolant leaks. Make sure the engine isn't overheating. Have engine running with ac on and inspect the coolant temp gauge. Also, Make sure the cooling fans are kicking on. If your stumped at this point, I'd have a good shop check out the ac system, make sure it wasn't overcharged with refrigerant. Maybe the ac compressor is failing or locking up.

Which part of Georgia are you located

Brake rotors will usually have a light coat of oxidation, but those definitely have more rust than usual. It's obvious he used some cheaper aftermarket ones from probably advanced auto or Autozone. Those cheap rotors are sometimes made from china. I mean, It will still perform fine. Your OEM lexus rotors would've been fine. I don't understand why didn't he just use and resurface/machine your original rotors.
