Driving my Tah (67,000 miles) down the highway and everything is perfectly fine, suddenly all of the check engine lights began to flash. I wasnt sure if it was an electrical glitch or not until the engine started knocking loudly. I was on a bridge in traffic and had no where to safely pull over. I had to drive a few miles further just to get to safety at which point the knocking became extremely loud and the entire car began shaking. I had the vehicle towed to the dealership where they informed me the lifters had gone out as well as the cam shaft. Apparently this is a very common occurrence among owners of this vehicle/similar vehicle. I am so grateful this is the one time my two small babies were not with me. It was a very scary situation and I was hours from home. This came completely out of no where without warning. Of course this happened 7,000 miles out of warranty. So now after paying over $70,000 for a vehicle that is barely 3 years old and only driven in town for the majority of that, I was stranded and now going to be out $10,000 to repair.
