Some days shifts from 2 to 3 wear like is slip bout other days is like nothing is wrong to the trans so whats the problem??

3 lights on simultaneously while driving Pulled over pronto & checked manual and Google Lexus forum. Checked for any fluid leaks/none and temp rock solid where always. Said check gas cap and 1-2 drives light go off its that's it. Drove the short distance home and parked it. Next day went to drive around neighborhood to see if lights would go off. Made it about 50 yards/loud engine noise. Parked curbside/turn off/checked under car/really fast pink fluid leak/assumed coolant. Walked back to car later/still leaking running down gutter and coolant reservoir appears empty. Power steer and tran fluid appear ok. Don't get why VSC and trac off would come on in connection with major coolant leak

the tail light is melted and need to know if it could be an electrical issue.

wife car battery was dead, when ask someone to help her with jumping cables to star car, they put cable wrongly but car did start.. when they remove cable and were going to move car... and accelerate pressing gas pedal.. the gas pedal don increase the
rpm's.. engine runs but not accelerate when gas pedal is press down..?

Several times I open the boot or trunk of my car manually I.e, I have to open one of the rear passenger doors to stretch my hand to open the boot of mycar,

Driver side temp control button fails to change temp from max cold to any higher temp

I had my tires balance, aligned, and rotated. My tire dealer said they see no problem with alignment parts. I Feel excessive vibration especially at speeds higher than 65 MPH Can feel it mainly on steering wheel. Hard for passenger to notice it.

What would it cost to make this repair. I have 210000 miles. on this car.

This is the first time in two & a half years! This problem started yesterday 13-11-2015.
