Buy a cheap scanner for $20 first

The shop def a rip off.  Oem MAF sensor is $14 on ebay.  Labor is 5 min you do yourself.

High mileage synthetic oil like from Mobile 1 helps with the leaks becasue they added chemicals that actually swell up the seals and reduce the leaking, but some say the added sulfur will clog the cats. 

If you have techstream you can use a new or virginized key and add it to the cars memory codes.

I just changed out a pair from my new-to-me GS350. It didn't go that well, so I have a pair of aftermarket CarID lamps that I had installed and then removed, and of course I have the old OEM lights that I eventually replaced with new OEM lights. One works fine, the other wouldn't self-level any more, and was locked in the low position. I'll put everything on eBay one of these days.

I also learned about aiming them. The headlight adjustment gear that I thought would change the height of the low beams actually moves them side to side. The gear that does change the height has been very carefully hidden by Lexus practically up against the fender, and invisible. If I didn't know it was there by looking at the old OEM light sitting on my garage floor I would have never found it. Getting a long screwdriver in there requires some guesswork too.

I agree the screw to adjust the headlights up and down are really in the back corner.  I can reach the passenger side but cant reach the driver side, whgich is aiming high.  All I can do is raise th passenger side higher also.  I dont want to take the front bumper off or the inner wheel well and fender to reach it.

Make sure the struts and strut mounts are in good shape, they usually wear out at 50-60k

Buy a cheap handheld obd2 scanner online.  You can reset the codes and see what comes back because some are related and some are not. 

I have original sensors on my 2007 gs450h so now they are 12 years old already.

I would say you bought some bogus sensors with weak batteries. 

I was thinking about doctorPrius

d4s  if you want factory is $40 each aftermarket is $8 each

Are you guys testing the battery cells under load charging and recharging?

I get the check battery light every 100 miles or so because I am sure some of my cells are weak, but I use a portable hand scanner to erase the code and the car drives fine for awhile.

When the CEl comes on sometimes the gas engine still runs when at a stop or idle when the batteries are full, when t should not

JVasquez even if the batteries are in bad shape if the car starts it doesnt need the hybrid juice the gas engine should be on all the time if there is gas in the tank. 

Its possible the dealer did not put enough oil in the car after the oil change, therefore was on borderline medium or low level, not the full level.   Its entirely possible to burn 1 quart of oil every 2-3k miles. 

The low engine oil sensor will light up when it is about 2.5 quarts low from the full line

The main reason for oil consumption is worn rings on the pistons, and this is more common as the mileage gets higher.

I burn about 1-1.5 quarts of oil every 5k miles on my 07 GS450h

You should check the dipstick oil level and match that with the miles driven before it reads low again.

The light comes on when the oil is low about 2.5 quarts from full level.   It is possible to have an oil change and the level is low but not enough to trigger the light.  Then after driving 2k burn 1 quart of oil and the light goes on.
