2007 RX400h

shaking upon startup every time. Toyota dealership advised it needed “tune-up”. Replaced spark plugs, coils, seals, timing belt 1 month ago.
still shaking - worse now and they don’t know why. Engine generic misfire code. All else working well until tonight.

Tonight it overheats after 10 min driving including last 5 min on interstate. Coolant was at 0.

Im about to trade this in. But wanted opinions first..
Thanks in advance!

 

No coolant? Where did it go? Did you ever see signs of leaking?

 

What is the color of oil? Does it look like sour cream?

 

Fill it up with coolant and trade it in as fast as you can. You have a blown head gasket. The Toyota dealership should have performed a compression test while changing the spark plugs which would have confirmed this.
