Engine light came on, engine started to make a rattling sound. The sound got worse when accelerating especially if I was attempting to go up a hill. I tried to make it to a mechanic, but the engine died on the way while attempting to make it up a big hill and would not restart. I had it towed to a shop, they said there was no oil in the car despite the fact that we always had our oil changed regularly. There was no sign of a leak. They had to put three quarts in it just for anything to show on the dipstick. The shop that I took it to did not do engine repair and recommended that I had it taken some place to have the engine rebuilt. Their theory was is that something blew and that the oil was being burned up. It happened so fast. One day I had a dependable care that I loved. The next it needed it's engine replaced. However, I knew I could not afford to pay for an engine to be rebuilt or replaced. So, I had to just have my car towed home.
Our vehicle has never had any issues, no check engine light, nothing. We were driving on the highway at approximately 60mph when there began to have a knocking, rattling noise from the engine. We pulled over to check it, no check engine light or anything still. Drove the vehicle to our repair shop, and on the way there, our engine blew. Still no check engine light came on. Our vehicle only had 133,000 miles on it, so of course it's out of warranty. Such a huge burden. We are now stuck having to replace the engine, while owing a crap ton of money on this SUV.
