Exhaust manifold/down pipe to cat. The exhaust pipe broke just past where it hooks up to the engine block. The breakage caused exhaust fumes to enter the cabin while not moving and at idle. The vehicle has 80k plus miles so was out of warranty. I fixed the issue myself since I have the technical and mechanical know how. There never was any check engine or other warning lights. Nothing caused the issue other than normal everyday driving. I had to disconnect the exhaust from the block and after the cat. I welded the pipe back together and fixed the issue. I could have bought a replacement part for over $400, but that was not possible on our budget at this time.

While driving on rainy day about 20 mph the engine would alternate between a power surge to no power. This continued for several minutes while driving (nowhere to pull over) until the engine completely died. Both the jerking forward and the shutoff while driving could have caused a horrible accident but fortunately we were lucky. The street was a city street, it was a very wet environment, and I was going straight. Traffic was stop and go so the car speed never was higher than about 20mph. All events occurred while SUV was in motion. Engine light was on. Took car in for service. They said nothing is currently a reported issue during the dtc status check but there was a "history" of "lin bus 14 lost communication with device", and a few reports regarding intake camshaft and exhaust camshaft issues. Have not heard the dealer's assessment yet.
