We were driving about 70mph on the highway when the engine started to make a knocking sound and losing power. We pulled over to see what was wrong and the car wouldn't start. We got a jump and had to buy a new battery due to it being drained. Got a new battery and pulled up the code for the knock sensor. We replaced it and new codes pulled up. The engine thru a rod with no warning of anything being wrong with the Traverse. It was well maintained with only 140,000 miles. The new battery we bought was drained almost immediately and needs to be charged for the Traverse to even start when the mechanic looked at it.
Engine began to make loud noise knocking noise while driving. Checked all fluids and they were all in good condition. Had a mechanic check, they said engine was shot and that they have seen a lot of the Traverse vehicles have engine failure.
