Bought car in 2021 and a few months later car started turning off while driving. Check engine light came on. . Replaced sensors and all was good. Fast forward to a week ago. . . Scheduled an oil change like I always do. . . Check engine light came on and engine started rattling. Stopped driving immediately. Checked oil and there was none. Added 3 quarts. Took to garage to have them take a look at it. He did the oil change but doesn't handle engine repairs and believes it is my timing belt. The vehicle only has about 65,000 miles on it and is a 2014. Common occurance apparently with this vehicle that needs to be addressed.
My 2014 Terrain stalled out at a stop sign. I restarted the truck and was it made a noise as though something was wrong with a belt. I went around the block and it stalled out 3 more times. I backed it into my driveway and noticed all of the oil on the ground. I had the truck put on a flatbed and towed to the dealer. According to the service department, the rear master seal blew. Somehow, as explained to me, water gets into the engine and freezes. This causes pressure and that is the cause of the damage. My Terrain turned 5 yrs old on 11/21/19 with only 50,249 miles. I am very disappointed. I have always owned a gm vehicle and have never had a problem until now. The warranty does not cover since it is 5 yrs old and I am out $3,000 for repairs. I don't even have the truck paid off yet. There has not been a recall or policy/warranty waiver.
