Engine Oil Leaking problems of the 2012 Toyota Highlander

Car has over 117,000 miles and is excessively consuming oil. There is no sign of leaks anywhere. I do not get any warning anywhere about low oil, all I see is a small message that sometimes blinks indicating �oil pressure�. Oil is not lasting 1000 miles. I thought maybe the oil was not properly filled but after a second oil change, same happened, oil empty with less than 1000 miles after an oil change. Car has been always kept with all recommended maintenance and all oil changes have been done every 5,000 as recommended by Toyota. Have never been in any accident that could cause any engine problem, seems this is a factory defect. In the electrical part, power back door does not close/open, there is a recall for that but no dealers in my area will fix it because one of the parts that is inside that motor is not listed in the recall specs and dealers will not fix unless I pay. I took the car to the dealer about 2 years ago. This refers to the warranty enhancement letter zg4.

Well before my oil changes are due, my vehicle needs more oil. There are no apparent exterior leaks but the oil has to be leaking somewhere or burning away through the exhaust.

With 1000 miles left on an oil change or so our car would randomly stall when you make certain turns. Occaisioanlly the oil light would pop one when it would stall. I checked the dipstick and you could not see anything on it. I added oil and took it into dealer. They are doing a consumption test to see how much we lose in 1000 miles. This vehicle only has 86,000 miles on it. We have no leaks and no visible smoke coming out of exhaust. This has me worried of similiar problems they had with one of there other 4cyl engines.

I was driving on a highway I heard a noise and smoke started coming from under the hood I pulled over and looked under the hood and saw smokr a tow truck driver who happened to be passing by pulled over and sure fire under the hood he put the fire out with a fire extinguisher I called nine-one-one four fire trucks to make sure the fire was completely extinguished my mechanic says a rod popped and punctured the oil tank which caused all the oil to leak out onto the side of the highway the firemen actually spread sand over it my insurance company he's refusing to repair the car because they say there was a maintenance issue because there was no oil in the car when they looked at it there was no oil in the car because it all leaked out on the side of the road I had just put oil in the car the previous day this happened on November 26th 20186.
