Owner complaint summary

The engine of this vehicle has been leaking from different areas consistently. The first leak was the timing cover gasket not properly sealing from manufacture. The dealership covered this under warranty without push back. I then identified a weep from the oil pan gasket during a normal oil change interval. This gasket leak was again from manufacture. I had watched this leak and it seemed to be getting worse over changes and evolved beyond a weep. I also found oil leaking onto one of the spark plugs when changed around 56K miles. I brought it to the dealership and received much push back, conducted oil consumption test for a visible leak, and then placed dye in the oil. It was identified as the oil pan gasket leaking. After much hesitation I eventually was able to get this "repaired" by the dealership at 57K miles. We are now nearly crossing 65K miles and a new leak has presented, enough to cause the low oil light to illuminate and pooling of oil on the access cover. I have yet to identify the source but I am again bringing this to the dealer. Safety concern is that my wife and toddler were an hour away from home on the side of the highway when this light illuminated and had to stop on the side of the road in the cold weather and turn the car off. They could be pulled over in unsafe areas or even be stranded in the cold - or risk seizing the engine to stay warm.
