Vehicle went into limp mode while driving on the highway. Onstar said it was the transmission. Checked the oil and smoke was billowing out of the dip stick and there was no oil. None of the sensors indicated that there was low oil. After sitting and waiting for a tow truck rechecked the oil with the dipstick and there was oil in it. Now requires a new engine.

2025 Yukon Denali - Purchased in July of 2025 Specifically to pull air stream trailer. Vehicle Was equipped with necessary tow package for this purpose! #1 problem: Went into limp mode, stopped in traffic, towed to dealer. One week to repair and replace fuel system. ( under 700 Miles ) #2 Problem: Went into limp mode while pulling trailer, vehicle lost all the transmission fluid on ground. In shop sixteen days waiting for new transmission parts. ( Under 700 Miles ) #3 Problem: Vehicle stopped in traffic, towed to dealer where it was determined it needed new engine. In shop Nov 27, 2025, still in shop as of Jan 14, 2026. No ETA on engine or delivery. ( Under 2000 Miles ) #4 Problem: During last failure attempt to use "on star" failed, still not resolved. This vehicle is a danger to the owner and its passengers as well as others when it simply stops working in the middle of a busy highway with a 23' trailer in tow. Not to mention I have $160,000 invested in a car and camper I have yet to be able to use.
