2011 TOYOTA VENZA Engine Problems

I had a 2011 Toyota Venza. Notice oil leakage. Took for oil and filter change and a check. Nothing was found, however four months later car began rattling and driving rough - I took to dealership and was told the Water Pump needed to be replaced. I have since found out that Toyota has had a many issues with the VVT-i Oil line failures AND Water Pump failures- Both that lead to a Failed Engine!! They fixed the water pump, however 45days later, my vehicles just stopped running as I was driving down the road. I checked oil - it was empty! Car would not start. I had car towed to dealer. I was then told 3days later that I needed a New Engine! That the Compressors were bad. In my research I found that when the compressor is starting to go out- the vehicle begins to run rough! This...

WHEN MY CAR HIT 100,000 MILES IT STARTED HAVING A ISSUE WHEN STARTING UP, I WOULD HEAR LIKE A GRINDING, WHEN I CHECKED THE OIL I HAD FOUND OUT THERE WAS MINIMAL OIL IN MY CAR, I ADDED OIL AND TOOK BY MY SHOP THEY TOLD ME ABOUT THIS ISSUE WITH OTHER TOYOTAS THAT HAVE THIS SAME ISSUE. OIL CONSUMPTION, I TOOK IT TO THE DEALER FOR THE NEXT FEW MONTHS, REPLACED THE OIL HOUSING, THE TUBING, HAD THEM RUNNING OIL CONSUMPTION TESTS, AND THEM TELLING ME THAT MY CAR PASSED AND CHARGING ME FOR ALL TEST. MY CAR NOW, IS EATING ABOUT 15 Q OF OIL EVERY 5000 MILES AND TOYOTA STILL SAYS THERE IS NOTHING WRONG WITH MY CAR. I AM WORRIED MY CAR WILL STALL ON A FREEWAY WHEN THERE IS NO MORE OIL IN MY ENGINE AND THERE IS NO WAY FOR ME TO KNOW, CAUSE...

CAR WAS SLOWLY PULLING INTO A PARKING SPOT, WHEN ALL OF A SUDDEN IT REVVED ITS ENGINE AND ACCELARATED. MY FOOT WAS ON THE BRAKE AND IT WOULD NOT STOP. THE REVVING NOISE WAS LOUD. I HIT A LARGE TREE THAT WAS LUCKILY AT THE END OF THE PARKING SPOT. THE TREE IS WHAT STOPPED THE CAR. WHEN THE CAR STOPPED, I LOOKED AND SAW WAS IN DRIVE. I WAS ABLE TO PUT IN REVERSE AND BACK UP AND PARK SAFELY. I SHUT THE CAR OFF IMMEDIATELY.
